  1. Streaming electrical potential anomaly along faults in geothermal areas

    Revil, A.; Pezard, P. A.

    Electrical potential anomalies are often measured associated with geothermal areas and volcanoes. In these systems, fluid flow is usually mostly restricted to faults and fracture networks. An equation describing electrical potential anomalies of electrokinetic nature associated with fluid upflow induced by a thermal source along faults is derived. The electrical potential anomaly is related to the depth of the thermal reservoir, the temperature difference between the surface and the reservoir of the geothermal area, the thermal expansion of water, and the streaming electrical potential coupling coefficient in the fault zone. A quantitative calculation of the electrokinetic anomaly is provided by comparing this model to a self-potential survey of the Cerro-Prieto geothermal field [Fitterman and Corwin, 1982]. The predictions of the model agree well with the field measurements.

    Using molecular dynamic simulations we study a family of continuous core-softened potentials consisting of a hard core, a shoulder at closest distances, and an attractive well at further distance. The repulsive shoulder and the well distances represent two length scales. We show that if the first scale, the shoulder, is repulsive or has a small well, the potential has a region in the pressure-temperature phase diagram with density, diffusion, and structural anomalies. However, if the closest scale becomes a deep well, the regions in the pressure-temperature phase diagram where the three anomalies are present shrink and disappear. This result helps in defining two length scales potentials that exhibit anomalies. PMID:19739858

    Geoanomalies generally are nonlinear, non-stationary and weak, especially in the land cover areas, however, the traditional methods of geoanomaly identification are usually based on linear theory. In past two decades, many power-law function models have been developed based on fractal concept in mineral exploration and mineral resource assessment, such that the density-area (C-A) model and spectrum-area model (S-A) suggested by Qiuming Cheng have played important roles in extracting geophysical and geochemical anomalies. Several power-law relationships are evident in geophysical potential fields, such as field value-distance, power spectrum-wave number as well as density-area models. The singularity index based on density-area model involves the first derivative transformation of the measure. Hence, we introduce the singularity analysis to develop a novel high-pass filter for extracting gravity and magnetic anomalies with the advantage of scale invariance. Furthermore, we suggest that the statistics of singularity indices can provide a new edge detection scheme for the gravity or magnetic source bodies. Meanwhile, theoretical magnetic anomalies are established to verify these assertions. In the case study from Nanling mineral district in south China and Qikou Depression in east China, compared with traditional geophysical filtering methods including multiscale wavelet analysis and total horizontal gradient methods, the singularity method enhances and extracts the weak anomalies caused by buried magmatic rocks more effectively, and provides more distinct boundary information of rocks. Moreover, the singularity mapping results have good correspondence relationship with both the outcropping rocks and known mineral deposits to support future mineral resource exploration. The singularity method based on fractal analysis has potential to be a new useful theory and technique for processing gravity and magnetic anomaly data.

    Abstract<p label="1">The formation of electric <span class="hlt">potential</span> over lunar magnetized regions is essential for understanding fundamental lunar science, for understanding the lunar environment, and for planning human exploration on the Moon. A large positive electric <span class="hlt">potential</span> was predicted and detected from single point measurements. Here, we demonstrate a remote imaging technique of electric <span class="hlt">potential</span> mapping at the lunar surface, making use of a new concept involving hydrogen neutral atoms derived from solar wind. We apply the technique to a lunar magnetized region using an existing dataset of the neutral atom <span class="hlt">energy</span> spectrometer SARA/CENA on Chandrayaan-1. Electrostatic <span class="hlt">potential</span> larger than +135 V inside the Gerasimovic <span class="hlt">anomaly</span> is confirmed.

The <span class="hlt">anomaly</span> is present for both hole- and electron-doped cuprates as well as the half-filled parent insulators with different <span class="hlt">energy</span> scales arising on either side of the phase diagram. While photoemission matrix elements clearly play a role in changing the aesthetic appearance of the band dispersion, i.e. creating a 'waterfall'-like appearance, they provide an inadequate description for the physics that underlies the strong band renormalization giving rise to the HEA. Model calculations of the single-band Hubbard Hamiltonian showcase the role played by correlations in the formation of the HEA and uncover significant differences in the HEA <span class="hlt">energy</span> scale for hole- and electron-doped cuprates. In addition, this approach properly captures the transfer of spectral weight accompanying doping in a correlated material and provides a unifying description of the HEA across both sides of the cuprate phase diagram.

The tetrahedral order in these liquids is induced by anisotropic hydrogen bonding or covalent interactions, or, in ionic melts, by an appropriate size ratio of the ions. Simple isotropic two-length scale models have been extensively used to understand the origin of <span class="hlt">anomalies</span> in complex liquids. However, single-component isotropic liquids characterized to date generally do not stabilize tetrahedral crystals, and in the few cases that they do, it was found that the liquids do not display <span class="hlt">anomalies</span> in the region of the tetrahedral crystal. This poses the question of whether it is possible for isotropic pair <span class="hlt">potentials</span> to display water-like phase behavior and <span class="hlt">anomalies</span>.

During the last years an increasing interest in the <span class="hlt">potential</span> field methods, i.e. gravimetry and magnetic, can be observed, even though data acquisition can cause considerable costs and logistic effort. Therefore, the specific advantages and disadvantages of the different methods were analyzed. In a case study, which was conducted in cooperation with RWE Dea and which is located in northern Germany, it was studied to which level of detail gravity and magnetic <span class="hlt">anomalies</span> can be interpreted jointly by 3D forward modelling. Special attention was paid to the individual residuals, i.e. those parts of the gravity and magnetic <span class="hlt">anomalies</span> which could not be interpreted satisfactorily by the joint structural / physical model. In a subsequent stage of the workflow this information was analyzed individually for each dataset to improve the geological interpretation and to identify and localize the sources of the <span class="hlt">anomalies</span> in more detail. For the discussed study several <span class="hlt">potential</span> field datasets of different resolution were available, which were first analyzed by means of field transformation. While the gravity <span class="hlt">anomalies</span> are mainly related to the occurrence of salt structures, the magnetic <span class="hlt">anomalies</span> seem to be controlled by deep structures, most probably by the magnetic basement. Some local magnetic <span class="hlt">anomalies</span> with amplitudes of less than 10 nT can be related to the rim synclines of the salt structures as well as to buried Pleistocene subglacial valleys. 3D forward models, constrained by existing structural information and rock physical data, have shown that, e.g., a common fitting of both <span class="hlt">anomaly</span> fields is not possible if homogenous densities and magnetizations are assigned to the different lithological units and while considering the geometry of the source bodies to be the same for both <span class="hlt">potential</span> field <span class="hlt">anomalies</span>. To explain the magnetic <span class="hlt">anomalies</span> a more detailed differentiation of the source bodies in terms of thin layers is required, while for the interpretation of the gravity <span class="hlt">anomalies</span> vertical density gradients must be considered for specific lithologies.

We regulate the expressions by incorporating a temporal-spatial cutoff in the (imaginary) time and transverse-spatial directions.

The full finite stress tensor is computed numerically for the two cases where explicit solutions to the differential equation are available, α =1 and 2. The <span class="hlt">energy</span> density exhibits an inverse linear divergence as the boundary is approached from the inside for a linear <span class="hlt">potential</span>, and a logarithmic divergence for a quadratic <span class="hlt">potential</span>. Finally, the interaction between two such walls is computed, and it is shown that the attractive Casimir pressure between the two walls also satisfies the principle of virtual work (i.e., the pressure equals the negative derivative of the <span class="hlt">energy</span> with respect to the distance between the walls).</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://adsabs.harvard.edu/abs/2015ExG....46..320R','NASAADS'); return false;" href="http://adsabs.harvard.edu/abs/2015ExG....46..320R"><span id="translatedtitle">Laboratory modelling of self-<span class="hlt">potential</span> <span class="hlt">anomalies</span> due to spherical bodies</span></a></p> <p><a target="_blank" href="http://adsabs.harvard.edu/abstract_service.html">NASA Astrophysics Data System (ADS)</a></p> <p>Roudsari, Mohamad Sadegh; Beitollahi, Ali</p> <p>2015-12-01</p> <p>The relationship between the self-<span class="hlt">potential</span> (SP) produced by a polarised sphere and its depth was studied in a laboratory experiment.

However, BEMSs can only achieve these <span class="hlt">energy</span> savings when properly tuned and controlled. Since indoor environment is dependent on uncertain criteria such as weather, occupancy, and thermal state, performance of BEMS can be sub-optimal at times. Unfortunately, the complexity of BEMS control mechanism, the large amount of data available and inter-relations between the data can make identifying these sub-optimal behaviors difficult. This paper proposes a novel Fuzzy <span class="hlt">Anomaly</span> Detection and Linguistic Description (Fuzzy-ADLD) based method for improving the understandability of BEMS behavior for improved state-awareness. The presented method is composed of two main parts: 1) detection of anomalous BEMS behavior and 2) linguistic representation of BEMS behavior. The first part utilizes modified nearest neighbor clustering algorithm and fuzzy logic rule extraction technique to build a model of normal BEMS behavior. The second part of the presented method computes the most relevant linguistic description of the identified <span class="hlt">anomalies</span>. The presented Fuzzy-ADLD method was applied to real-world BEMS system and compared against a traditional alarm based BEMS. In six different scenarios, the Fuzzy-ADLD method identified anomalous behavior either as fast as or faster (an hour or more), that the alarm based BEMS. In addition, the Fuzzy-ADLD method identified cases that were missed by the alarm based system, demonstrating <span class="hlt">potential</span> for increased state-awareness of abnormal building behavior.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://www.pubmedcentral.nih.gov/articlerender.fcgi?tool=pmcentrez&artid=1779293','PMC'); return false;" href="http://www.pubmedcentral.nih.gov/articlerender.fcgi?tool=pmcentrez&artid=1779293"><span id="translatedtitle">Developing global climate <span class="hlt">anomalies</span> suggest <span class="hlt">potential</span> disease risks for 2006 2007</span></a></p> <p><a target="_blank" href="http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?DB=pmc">PubMed Central</a></p> <p>Anyamba, Assaf; Chretien, Jean-Paul; Small, Jennifer; Tucker, Compton J; Linthicum, Kenneth J</p> <p>2006-01-01</p> <p>Background El Nio/Southern Oscillation (ENSO) related climate <span class="hlt">anomalies</span> have been shown to have an impact on infectious disease outbreaks. The Climate Prediction Center of the National Oceanic and Atmospheric Administration (NOAA/CPC) has recently issued an unscheduled El Nio advisory, indicating that warmer than normal sea surface temperatures across the equatorial eastern Pacific may have pronounced impacts on global tropical precipitation patterns extending into the northern hemisphere particularly over North America. Building evidence of the links between ENSO driven climate <span class="hlt">anomalies</span> and infectious diseases, particularly those transmitted by insects, can allow us to provide improved long range forecasts of an epidemic or epizootic. We describe developing climate <span class="hlt">anomalies</span> that suggest <span class="hlt">potential</span> disease risks using satellite generated data. Results Sea surface temperatures (SSTs) in the equatorial east Pacific ocean have anomalously increased significantly during July October 2006 indicating the typical development of El Nio conditions. The persistence of these conditions will lead to extremes in global-scale climate <span class="hlt">anomalies</span> as has been observed during similar conditions in the past. Positive Outgoing Longwave Radiation (OLR) <span class="hlt">anomalies</span>, indicative of severe drought conditions, have been observed across all of Indonesia, Malaysia and most of the Philippines, which are usually the first areas to experience ENSO-related impacts. This dryness can be expected to continue, on average, for the remainder of 2006 continuing into the early part of 2007. During the period November 2006 January 2007 climate forecasts indicate that there is a high probability for above normal rainfall in the central and eastern equatorial Pacific Islands, the Korean Peninsula, the U.S. Gulf Coast and Florida, northern South America and equatorial east Africa. Taking into consideration current observations and climate forecast information, indications are that the following regions are at increased risk for disease outbreaks: Indonesia, Malaysia, Thailand and most of the southeast Asia Islands for increased dengue fever transmission and increased respiratory illness; Coastal Peru, Ecuador, Venezuela, and Colombia for increased risk of malaria; Bangladesh and coastal India for elevated risk of cholera; East Africa for increased risk of a Rift Valley fever outbreak and elevated malaria; southwest USA for increased risk for hantavirus pulmonary syndrome and plague; southern California for increased West Nile virus transmission; and northeast Brazil for increased dengue fever and respiratory illness. Conclusion The current development of El Nio conditions has significant implications for global public health. Extremes in climate events with above normal rainfall and flooding in some regions and extended drought periods in other regions will occur. Forecasting disease is critical for timely and efficient planning of operational control programs. In this paper we describe developing global climate <span class="hlt">anomalies</span> that suggest <span class="hlt">potential</span> disease risks that will give decision makers additional tools to make rational judgments concerning implementation of disease prevention and mitigation strategies.

Throughout summer and fall 2014 and winter 2015, El Niño Watch, issued by the US National Oceanic and Atmospheric Administration, assessed likely El Niño development during the Northern Hemisphere fall and winter, persisting into spring 2015. Methods: We identified geographic regions where environmental conditions may increase infectious disease transmission if the predicted El Niño occurs using El Niño indicators (Sea Surface Temperature [SST], Outgoing Longwave Radiation [OLR], and rainfall <span class="hlt">anomalies</span>) and literature review of El Niño-infectious disease associations. Results: SSTs in the equatorial Pacific and western Indian Oceans were anomalously elevated during August-October 2014, consistent with a developing weak El Niño event. Teleconnections with local climate is evident in global precipitation patterns, with positive OLR <span class="hlt">anomalies</span> (drier than average conditions) across Indonesia and coastal southeast Asia, and negative <span class="hlt">anomalies</span> across northern China, the western Indian Ocean, central Asia, north-central and northeast Africa, Mexico/Central America, the southwestern United States, and the northeastern and southwestern tropical Pacific. Persistence of these conditions could produce environmental settings conducive to increased transmission of cholera, dengue, malaria, Rift Valley fever, and other infectious diseases in regional hotspots as during previous El Niño events. Discussion and Conclusions: The current development of weak El Niño conditions may have significant <span class="hlt">potential</span> implications for global public health in winter 2014-spring 2015. Enhanced surveillance and other preparedness measures in predicted infectious disease hotspots could mitigate health impacts.

Relevant to this issue, it has been shown that 230Th has been accumulating on the equatorial seabed faster than its production from radioactive decay in the overlying water column during the Holocene (Marcantonio et al. in Paleoceanography 16:260-267, 2001). Some researchers have argued that this reflects the deposition of particles with adsorbed 230Th carried by bottom currents towards the equator ("focusing"). If correct, this effect may combine with high pelagic productivity, which is also centered on the equator, to yield a characteristic signature of high accumulation rates marking the paleoequator in older deposits. Here we evaluate <span class="hlt">potential</span> evidence that such an equatorial feature existed in the geological past. Seismic reflection data from seven meridional transects suggest that a band of equatorially enhanced accumulation of restricted latitude was variably developed, both spatially and temporally. It is absent in the interval 14.25-20.1 Ma but is well developed for the interval 8.55-14.25 Ma. We also examined eolian dust accumulation rate histories generated from scientific drilling data. A dust accumulation rate <span class="hlt">anomaly</span> near the modern equator, which is not obviously related to the inter-tropical convergence zone, is interpreted as caused by focusing. Accumulation rates of Ba and P2O5 (proxies of export production) reveal a static equatorial signature, which suggests that the movement of the Pacific plate over the period 10-25 Ma was modest. The general transition from missing to well-developed focusing signatures around 14.25 Ma in the seismic data coincides with the mid-Miocene development of the western boundary current off New Zealand. This current supplies the Pacific with deep water from Antarctica, and could therefore imply a <span class="hlt">potential</span> paleoceanographic or paleoclimatic origin. At 10.05-14.25 Ma, the latitudes of the seismic <span class="hlt">anomalies</span> are up to ~2 different from the paleoequator predicted by Pacific plate-hotspot models, suggesting <span class="hlt">potentially</span> a small change in the hotspot latitudes relative to the present day (although this inference depends on the precise form of the deposition around the equator). The Ba and P2O5 <span class="hlt">anomalies</span>, on the other hand, are broadly compatible with plate models predicting slow northward plate movement over 10-25 Ma.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://www.osti.gov/scitech/servlets/purl/983661','SCIGOV-STC'); return false;" href="http://www.osti.gov/scitech/servlets/purl/983661"><span id="translatedtitle">Alaska's renewable <span class="hlt">energy</span> <span class="hlt">potential</span>.</span></a></p> <p><a target="_blank" href="http://www.osti.gov/scitech">SciTech Connect</a></p> <p>Not Available</p> <p>2009-02-01</p> <p>This paper delivers a brief survey of renewable <span class="hlt">energy</span> technologies applicable to Alaska's climate, latitude, geography, and geology.

The Hilbert-Huang Transform is applied on surface displacement data to remove the effects of noise, semi-annual and annual cycles, and the long-term plate movements. The residual displacements have similar orientations when earthquake-related stress accumulates in the crust.

That algorithm is an upgraded version of the 'Staylor' algorithm. Calculations are performed for a 280X280 km equal-area grid system over the globe based on 3-hourly input data. A bi-linear interpolation process is used to estimate data output values on a 1 X 1 degree grid system over the globe. Maximum <span class="hlt">anomalies</span> are examined relative to El Nino and La Nina events in the tropical Pacific Ocean. Maximum year-to-year <span class="hlt">anomalies</span> over the globe are provided for a 10-year period. The data may assist in the design of systems with increased reliability. It may also allow for better planning for emergency assistance during some atypical events.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://adsabs.harvard.edu/abs/2014JPhB...47l4034K','NASAADS'); return false;" href="http://adsabs.harvard.edu/abs/2014JPhB...47l4034K"><span id="translatedtitle">Temperature-resolution <span class="hlt">anomalies</span> in the reconstruction of time dynamics from <span class="hlt">energy</span>-loss experiments</span></a></p> <p><a target="_blank" href="http://adsabs.harvard.edu/abstract_service.html">NASA Astrophysics Data System (ADS)</a></p> <p>Kogar, Anshul; Vig, Sean; Gan, Yu; Abbamonte, Peter</p> <p>2014-06-01</p> <p>Inelastic scattering techniques provide a powerful approach to studying electron and nuclear dynamics, via reconstruction of a propagator that quantifies the time evolution of a system.

Various amplitudes of gravity and aeromagnetic <span class="hlt">anomalies</span> are observed around the lake and surrounding region. In the gravity <span class="hlt">anomaly</span> map, contour intensity is observed from the north of Mus city center toward Lake Van. There is a possibility that the NAF extends from here to the lake. Because there is no gravity data within the lake, the extension of the NAF is unknown and uncertain in the lake and to the east. Meanwhile, it is observed from the aeromagnetic <span class="hlt">anomalies</span> that there are several positive and negative amplitude <span class="hlt">anomalies</span> aligned around a slightly curved line in the east-west direction. The same curvature becomes much clearer in the analytic signal transformation map. The volcanic mountains of Nemrut and Suphan, and magnetic <span class="hlt">anomalies</span> to the east of the Lake Van are all lined up and extended with this slightly curved line, provoking thoughts that a fault zone that was not previously mapped may exist. The epicenter of the major earthquake event that occurred on October 23, 2011 is located on this fault zone. The fault plane solution of this earthquake indicates a thrust fault in the east-west direction, consistent with the results of this study. Volcanic mountains in this zone are accepted as still being active because of gas seepages from their calderas, and magnetic <span class="hlt">anomalies</span> are caused by buried causative bodies, probably magmatic intrusions. Because of its magmatic nature, this zone could be a good prospect for geothermal <span class="hlt">energy</span> exploration. In this study, the basement of the Van Basin was also modelled three-dimensionally (3D) in order to investigate its hydrocarbon <span class="hlt">potential</span>, because the first oil production in Anatolia was recorded around the Kurzot village in this basin. According to the 3D modelling results, the basin is composed of three different depressions aligned in the N-S direction and many prospective structures were observed between and around these depressions where the depocenter depths may reach down to 10 km.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://www.ncbi.nlm.nih.gov/pubmed/17886018','PUBMED'); return false;" href="http://www.ncbi.nlm.nih.gov/pubmed/17886018"><span id="translatedtitle">Effects of advancing age on the processing of semantic <span class="hlt">anomalies</span> in adults: evidence from event-related brain <span class="hlt">potentials</span>.</span></a></p> <p><a target="_blank" href="http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?DB=pubmed">PubMed</a></p> <p>Faustmann, Anja; Murdoch, Bruce E; Finnigan, Simon P; Copland, David A</p> <p>2007-01-01</p> <p>Age-related changes in the processing of sentence-embedded semantic <span class="hlt">anomalies</span> were examined using auditory event-related <span class="hlt">potentials</span> (ERPs).

Based on NCEP-NOAA reanalysis data this analysis explores a number of key parameters that cause a range of EN types over the period 1980-2013. EN events are divided into three types depending on the spatial and temporal evolution of the sea surface temperature <span class="hlt">anomalies</span> (SSTA): Central Pacific (CPEN), Eastern Pacific (EPEN), and Hybrid (HBEN). We find that EN is a continuous spectrum of events with CPEN and EPEN as the end members. This spectrum mainly depends on two key parameters: the 130°E-160°E Western Pacific 5-250 m subsurface oceanic <span class="hlt">potential</span> temperature <span class="hlt">anomaly</span> about 1 year before the EN peak (typically January and February), and the 140°E-160°W cumulative zonal wind <span class="hlt">anomaly</span> (ZWA) between onset and peak of the EN event. Using these two parameters, about 70 % of the total variance of the maximum SSTA realised in different Niño regions can already be explained up to 6 months before the maximum SSTA occurs. This offers a rather simple <span class="hlt">potential</span> for ENSO prediction. A necessary condition for the evolution of an EPEN, the Western Pacific is in the recharged state. Strong and sustained westerly wind <span class="hlt">anomalies</span> in Western Pacific can then trigger a Kelvin wave propagating to the eastern Pacific. Both parameters, <span class="hlt">potential</span> temperature and zonal wind <span class="hlt">anomaly</span>, constructively interfere. For a CPEN, these parameters are much less important. Kelvin wave propagation is not involved in the evolution of the event. Instead, the Central Pacific warming is caused locally by a zonal advection feedback and local air-sea interaction as already demonstrated in previous studies. The HBEN occurs when both parameters interfere in different ways: (1) Western Pacific is weakly charged, but strong westerly ZWA are observed that reduce the equatorial upwelling in the Central Pacific while the triggered Kelvin wave is too weak to have a significant effect; (2) Western Pacific is strongly charged but only weak westerly ZWA develop, so that the resulting Kelvin wave cannot fully extend into the eastern-most Pacific.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://adsabs.harvard.edu/abs/1995FBS....19..203F','NASAADS'); return false;" href="http://adsabs.harvard.edu/abs/1995FBS....19..203F"><span id="translatedtitle">Assessment of Triton <span class="hlt">Potential</span> <span class="hlt">Energy</span></span></a></p> <p><a target="_blank" href="http://adsabs.harvard.edu/abstract_service.html">NASA Astrophysics Data System (ADS)</a></p> <p>Friar, J.

Our design is driven by the needs of users such as law enforcement personnel who must make decisions by evaluating threat signatures in urban settings. The most efficient tool available to identify the nature of the threat object is real-time gamma spectroscopic analysis, as it is fast and has a very low probability of producing false positive alarm conditions. Urban radiological searches are inherently challenged by the rapid and large spatial variation of background gamma radiation, the presence of benign radioactive materials in terms of the normally occurring radioactive materials (NORM), and shielded and/or masked threat sources. Multiple spectral <span class="hlt">anomaly</span> detection algorithms have been developed by national laboratories and commercial vendors. For example, the Gamma Detector Response and Analysis Software (GADRAS) a one-dimensional deterministic radiation transport software capable of calculating gamma ray spectra using physics-based detector response functions was developed at Sandia National Laboratories. The nuisance-rejection spectral comparison ratio <span class="hlt">anomaly</span> detection algorithm (or NSCRAD), developed at Pacific Northwest National Laboratory, uses spectral comparison ratios to detect deviation from benign medical and NORM radiation source and can work in spite of strong presence of NORM and or medical sources.

The resulting orthogonal perturbation patterns are designed such that they pick up typical balanced <span class="hlt">anomaly</span> structures in space and time and between variables. The metric used to set up the eigen problem is taken either as the weighted total <span class="hlt">energy</span> with its zonal, meridional kinetic and available <span class="hlt">potential</span> <span class="hlt">energy</span> terms having equal contributions, or the weighted ocean heat content in which a disturbance is applied only to the initial temperature fields. The choices of a reference state for defining the initial <span class="hlt">anomalies</span> are such that either perturbations on seasonal timescales and or on interannual timescales are constructed. These project a-priori only the slow modes of the ocean physical processes, such that the disturbances grow mainly in the Western Boundary Currents, in the Antarctic Circumpolar Current and the El Nino Southern Oscillation regions.

It is rare that specific rock units can be identified to which groundwater <span class="hlt">anomalies</span> can be attributed. In this study, primary arsenic minerals, such as a Y-As bearing phase and a Sr-Al-As phase, have been identified in the Cenozoic volcanic tuff from El Mimbre area, at the northeast part of Tabalaopa Basin, the City of Chihuahua. Tabalaopa Basin is one of the sources for groundwater of the City of Chihuahua. The volcanic strata and the unconsolidated Quaternary deposit serve as the groundwater reservoir. The El Mimbre area demonstrates elevated groundwater arsenic concentrations, with 5 wells having values greater than 20 ppb. Small hills of Cenozoic volcanic tuff lie immediately up gradient to the northeast adjacent to the groundwater <span class="hlt">anomaly</span>. Electron microprobe elemental x-ray maps have been applied to detect arsenic distribution in the samples. The volcanic rocks are reddish welded ash flow tuff and rhyolite with mainly sanidine, quartz, and biotite. The Y-As phase (a possible hydrated chernovite YAsO4) exists as inclusions in the biotite. The Y-As phase could be the primary arsenic mineral formed in the crystallization stage of the magma. After the eruption, the vapor phase from the diagenetic welding of volcanic tuff formed the euhedral Sr-Al- As phase in the lithophysal cavities. The wavelength peak scan and quantitative analysis present that the euhedral arsenic minerals are mainly arsenogoyazite (SrAl3[(OH)5(AsO4)2])H2O. There are euhedral alkali feldspars and ilmenite co-existing with arsenogoyazite, so the arsenogoyazite could be the vapor phase derived. The arsenic mineral petrogenesis sequences can be 1) the formation of chernoviet, 2) vapor stage alteration and the precipitation of arsenogoyazite in the cavities. It is hypothesized that the relative soluble arsenogoyazite is leached by meteoric water and provides the arsenic in the nearby groundwater. Based on current study, the arsenic <span class="hlt">anomaly</span> in the Tabalaopa Basin aquifer can be mainly from the arsenic minerals in the adjacent volcanic rocks.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://www.osti.gov/scitech/servlets/purl/7037830','SCIGOV-STC'); return false;" href="http://www.osti.gov/scitech/servlets/purl/7037830"><span id="translatedtitle">The <span class="hlt">potential</span> of renewable <span class="hlt">energy</span></span></a></p> <p><a target="_blank" href="http://www.osti.gov/scitech">SciTech Connect</a></p> <p>Not Available</p> <p>1990-03-01</p> <p>On June 27 and 28, 1989, the US Department of <span class="hlt">Energy</span> (DOE) national laboratories were convened to discuss plans for the development of a National <span class="hlt">Energy</span> Strategy (NES) and, in particular, the analytic needs in support of NES that could be addressed by the laboratories.

In consideration of one major noise source is the fractal noise (or called 1/f noise) with a power spectral density of 1/fa (0<a<2), which is non-stationary, self-similarity and long-range correlation. Meanwhile the orthonormal wavelet decomposition can play the role of a Karhunen-Loève-type expansion to the 1/f-type signal by its decorrelation abilities, an effective <span class="hlt">energy</span> detection method based on undecimated discrete wavelet transform (UDWT) is proposed in this paper. Firstly, the foundations of magnetic <span class="hlt">anomaly</span> detection and UDWT are introduced in brief, while a possible detection system based on giant magneto-impedance (GMI) magnetic sensor is also given out. Then our proposed <span class="hlt">energy</span> detection based on UDWT is described in detail, and the probabilities of false alarm and detection for given the detection threshold in theory are presented. It is noticeable that no a priori assumptions regarding the ferromagnetic target or the magnetic noise probability are necessary for our method, and different from the discrete wavelet transform (DWT), the UDWT is shift invariant. Finally, some simulations are performed and the results show that the detection performance of our proposed detector is better than that of the conventional <span class="hlt">energy</span> detector even utilized in the Gaussian white noise, especially when the spectral parameter α is less than 1.0. In addition, a real-world experiment was done to demonstrate the advantages of the proposed method.

Certain radiologic findings reported in this condition overlap with those caused by child abuse. However, cervical spine defects simulating cervical spine fracture, a known result of nonaccidental pediatric trauma, have not been reported previously in this illness. Objective To assess the frequency of cervical spine <span class="hlt">anomalies</span> in Menkes disease after discovery of an apparent C2 posterior arch defect in a child participating in a clinical trial. Materials and methods We examined cervical spine radiographs obtained in 35 children with Menkes disease enrolled in a clinical trial at the National Institutes of Health Clinical Center. Results Four of the 35 children with Menkes disease had apparent C2 posterior arch defects consistent with spondylolysis or incomplete/delayed ossification. Conclusion Defects in C2 were found in 11% of infants and young children with Menkes disease. Discovery of cervical spine defects expands the spectrum of radiologic findings associated with this condition. As with other skeletal abnormalities, this feature simulates nonaccidental trauma. In the context of Menkes disease, suspicions of child abuse should be considered cautiously and tempered by these findings to avoid unwarranted accusations.

So far, assessments of the skill of atmospheric and terrestrial variability in decadal predictions, however, have not been encouraging. Similarly, in the context of seasonal climate variability, teleconnections between SSTs associated with PDO and AMO and terrestrial climate have also been noted, but the same SST information used in predictive mode has failed to demonstrate convincing gains in skill. Are these results an artifact of model biases, or more a consequence of some fundamental property of coupled evolution of ocean-atmosphere system in extratropical latitudes, and the manner in which extratropical SST <span class="hlt">anomalies</span> modulate (or constrain) atmospheric variability? Based on revisiting an analysis of a simple model that replicates the essential characteristics of coupled ocean-atmosphere interaction in extratropical latitudes, it is demonstrated that lack of additional skill in predicting atmospheric and terrestrial variability is more a consequence of fundamental characteristics of coupled evolution of ocean-atmosphere system. The results based on simple models are also substantiated following an analysis of a set of seasonal hindcasts with a fully coupled model.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://adsabs.harvard.edu/abs/1998JChPh.108..203A','NASAADS'); return false;" href="http://adsabs.harvard.edu/abs/1998JChPh.108..203A"><span id="translatedtitle"><span class="hlt">Potential</span> <span class="hlt">energy</span> surface of cyclooctatetraene</span></a></p> <p><a target="_blank" href="http://adsabs.harvard.edu/abstract_service.html">NASA Astrophysics Data System (ADS)</a></p> <p>Andrés, José L.; Castaño, Obis; Morreale, Antonio; Palmeiro, Raul; Gomperts, Roberto</p> <p>1998-01-01</p> <p>We present a theoretical study of the cyclooctatetraene (COT) molecule.

Inverse Compton scattering of the microwave background by the emergent positrons produces a bump in the diffuse 100-200 MeV {gamma}-ray background that would protrude from the observed background at these <span class="hlt">energies</span>. The positrons are thus constrained to emerge from the decay process at a typical <span class="hlt">energy</span> between {approx}100 GeV and {approx}250 GeV.

Any {gamma}-rays produced directly by the dark-matter decay leads to an additional signal that makes the observational limits more severe. A similar constraint on the <span class="hlt">energy</span> of emergent positrons from annihilation in dark-matter substructures is argued to exist, according to recent estimates of enhancement in low-mass dark-matter substructures, and improved simulations of such substructure will further sharpen this constraint.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://adsabs.harvard.edu/abs/2005JPCM...17.7817S','NASAADS'); return false;" href="http://adsabs.harvard.edu/abs/2005JPCM...17.7817S"><span id="translatedtitle">Dielectric anisotropy, volume <span class="hlt">potential</span> <span class="hlt">anomalies</span> and the persistent Maxwellian equivalent body</span></a></p> <p><a target="_blank" href="http://adsabs.harvard.edu/abstract_service.html">NASA Astrophysics Data System (ADS)</a></p> <p>Simeonova, Margarita; Gimsa, Jan</p> <p>2005-12-01</p> <p><span class="hlt">Potentially</span>, lipid membranes possess a high tangential conductivity and permittivity due to their surface charges and the in-plane orientation of the headgroup dipoles.

Accordingly, we described spherical vesicles by an aqueous core covered by three shells. For a theoretical comparison, models with an anisotropic single shell and anisotropic homogeneous spheres were also considered. Two effects can be clearly demonstrated.

We used a GPR operating at 16 and 100 MHz to perform structural mapping at several different locations. Radar studies were combined with transient electromagnetic soundings and infrared spectroscopy to assess the effect of soil conductivity and geochemistry on identification of subsurface structures. Our results show that, even with a relatively high amount of irons oxides (~14 %), GPR penetration depths of 50 m were achieved with the 100 MHz antenna and penetration depths of 150 m were achieved with the 16 MHz antenna. These depths of investigation may be attributable to the high porosity of the soil at the studied areas, which lowered the electrical losses, thus favoring a relatively deep penetration of the radar wave.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://hdl.handle.net/2060/20040081281','NASA-TRS'); return false;" href="http://hdl.handle.net/2060/20040081281"><span id="translatedtitle">Bangui <span class="hlt">Anomaly</span></span></a></p> <p><a target="_blank" href="http://ntrs.nasa.gov/search.jsp">NASA Technical Reports Server (NTRS)</a></p> <p>Taylor, Patrick T.</p> <p>2004-01-01</p> <p>Bangui <span class="hlt">anomaly</span> is the name given to one of the Earth s largest crustal magnetic <span class="hlt">anomalies</span> and the largest over the African continent. It covers two-thirds of the Central African Republic and therefore the name derives from the capitol city-Bangui that is also near the center of this feature. From surface magnetic survey data Godivier and Le Donche (1962) were the first to describe this <span class="hlt">anomaly</span>. Subsequently high-altitude world magnetic surveying by the U.S. Naval Oceanographic Office (Project Magnet) recorded a greater than 1000 nT dipolar, peak-to-trough <span class="hlt">anomaly</span> with the major portion being negative (figure 1). Satellite observations (Cosmos 49) were first reported in 1964, these revealed a 40nT <span class="hlt">anomaly</span> at 350 km altitude. Subsequently the higher altitude (417-499km) POGO (Polar Orbiting Geomagnetic Observatory) satellite data recorded peak-to-trough <span class="hlt">anomalies</span> of 20 nT these data were added to Cosmos 49 measurements by Regan et al. (1975) for a regional satellite altitude map. In October 1979, with the launch of Magsat, a satellite designed to measure crustal magnetic <span class="hlt">anomalies</span>, a more uniform satellite altitude magnetic map was obtained. These data, computed at 375 km altitude recorded a -22 nT <span class="hlt">anomaly</span> (figure 2). This elliptically shaped <span class="hlt">anomaly</span> is approximately 760 by 1000 km and is centered at 6%, 18%. The Bangui <span class="hlt">anomaly</span> is composed of three segments; there are two positive <span class="hlt">anomalies</span> lobes north and south of a large central negative field. This displays the classic pattern of a magnetic anomalous body being magnetized by induction in a zero inclination field. This is not surprising since the magnetic equator passes near the center of this body.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://eric.ed.gov/?q=Geothermal&pg=4&id=EJ166697','ERIC'); return false;" href="http://eric.ed.gov/?q=Geothermal&pg=4&id=EJ166697"><span id="translatedtitle">Geothermal <span class="hlt">Energy</span> <span class="hlt">Potential</span> in Western United States</span></a></p> <p><a target="_blank" href="http://www.eric.ed.gov/ERICWebPortal/search/extended.jsp?_pageLabel=advanced">ERIC Educational Resources Information Center</a></p> <p>Pryde, Philip R.</p> <p>1977-01-01</p> <p>Reviews types of geothermal <span class="hlt">energy</span> sources in the western states, including hot brine systems and dry steam systems.

The duration of the data set, which is comprised of Aqua-MODIS land surface temperature (LST) night-time snapshot images, is 62 days. In order to quantify variations of LST data obtained from satellite images, the air temperature (AT) data derived from the meteorological station close to the earthquake epicenter has been taken into account. For the models examined here, results indicate the following: (i) ARIMA models, which are the most widely used in the time series community for short-term forecasting, are quickly and easily implemented, and can efficiently act through linear solutions. (ii) A multilayer perceptron (MLP) feed-forward neural network can be a suitable non-parametric method to detect the anomalous changes of a non-linear time series such as variations of LST. (iii) Since SVMs are often used due to their many advantages for classification and regression tasks, it can be shown that, if the difference between the predicted value using the SVM method and the observed value exceeds the pre-defined threshold value, then the observed value could be regarded as an <span class="hlt">anomaly</span>. (iv) ANN and SVM methods could be powerful tools in modeling complex phenomena such as earthquake precursor time series where we may not know what the underlying data generating process is. There is good agreement in the results obtained from the different methods for quantifying <span class="hlt">potential</span> <span class="hlt">anomalies</span> in a given LST time series.

In the presence of imperfect sources, large-scale gradients or anisotropies in the dark <span class="hlt">energy</span> mean that the CMB sky will be distorted anisotropically on its way to us by the ISW effect. The signal covariance matrix then becomes non-diagonal for small multipoles, but at ℓ ≳ 20 the anisotropy is negligible for any reasonably probable values of the already constrained dark <span class="hlt">energy</span> fluid parameters. As a consequence, only possible large-scale anisotropies are studied in this paper. We parametrize possible violations of rotational invariance in the late universe by the magnitude of a post-Friedmannian deviation from isotropy and its scale dependence, where the deviation from isotropy is modeled through a mismatch between the φ and ψ <span class="hlt">potentials</span> that arise due to anisotropic stresses caused by some (unknown) mechanism. In this sense, our model is general. In this paper we explore the possibility that the stresses are caused by an imperfect dark <span class="hlt">energy</span> component in the form of a vector field aligned with some axis. This way we may obtain hints of the possible imperfect nature of dark <span class="hlt">energy</span> and the large-angle anomalous features in the CMB. A robust statistical analysis, subjected to various tests and consistency checks, is performed to compare the predicted correlations with those obtained from the satellite-measured CMB full sky maps. The preferred axis points toward (l,b) = (168°, -31°) and the amplitude of the anisotropy is ϖ0 = (0.51 ± 0.94) (1σ deviation quoted). The best fit model has a steep blue anisotropic spectrum (nde = 3.1 ± 1.5). In light of recent studies, the model provides an interesting extension of the standard model of cosmology, since it is able to account for the apparent deficit in large-scale power in the spectrum through a physically motivated late time ISW effect. Further studies of this class of models are justified by the results of the analysis, which suggest that it cannot be ruled out at present.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://adsabs.harvard.edu/abs/1981aes.....4.1727W','NASAADS'); return false;" href="http://adsabs.harvard.edu/abs/1981aes.....4.1727W"><span id="translatedtitle">Sources and <span class="hlt">potential</span> uses of wave <span class="hlt">energy</span></span></a></p> <p><a target="_blank" href="http://adsabs.harvard.edu/abstract_service.html">NASA Astrophysics Data System (ADS)</a></p> <p>Woodbridge, D.

Modelling current and anticipated changes of the surface <span class="hlt">energy</span> balance requires an understanding of the spatio-temporal interactions between LST and land cover. This paper investigated the accuracy of MODIS LST V5 1 km level 3 product and its spatio-temporal sensitivity to land cover properties in a Canadian High Arctic permafrost landscape. Land cover ranged from fully vegetated moss/segde grass tundra to sparsely vegetated bare soil and barren areas. Daily mean MODIS LST were compared to in-situ radiometer measurements over wet tundra for three summers and two winters in 2008, 2009, and 2010. MODIS LST showed an accuracy of 1.8°C and a RMSE of 3.8°C in the total observation period including both summer and winter. Agreement was lowest during summer 2009 and freeze-back periods which were associated with prevailing overcast conditions. A multi-year <span class="hlt">anomaly</span> analysis revealed robust spatio-temporal patterns taking into account the found uncertainty and different atmospheric conditions. Summer periods with regional mean LST larger than 5°C showed highest spatial diversity with four distinct <span class="hlt">anomaly</span> classes. Dry ridge areas heated up most whereas wetland areas and dry barren surfaces with high albedo were coolest. Mean inter-annual differences of LST <span class="hlt">anomalies</span> for different land cover classes were less than 1°C. However, spatial pattern showed fewer positive <span class="hlt">anomalies</span> in 2010 suggesting differences in surface moisture due to inter­annual differences in the amount of end-of-winter snow. Presented summer LST <span class="hlt">anomalies</span> might serve as a baseline against which to evaluate past and future changes in land surface properties with regard to the surface <span class="hlt">energy</span> balance. Sub-temporal heterogeneity due to snow or ice on/off as well as the effect of subpixel water bodies has to be taken into account. A multi-sensor approach combining thermal satellite measurements with high-resolution optical and radar imagery therefore promises to be an effective tool for a dynamic, process-based ecosystem monitoring scheme.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://www.ncbi.nlm.nih.gov/pubmed/17001017','PUBMED'); return false;" href="http://www.ncbi.nlm.nih.gov/pubmed/17001017"><span id="translatedtitle">A theory for the atmospheric <span class="hlt">energy</span> spectrum: depth-limited temperature <span class="hlt">anomalies</span> at the tropopause.</span></a></p> <p><a target="_blank" href="http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?DB=pubmed">PubMed</a></p> <p>Tulloch, R; Smith, K S</p> <p>2006-10-01</p> <p>The horizontal spectra of atmospheric wind and temperature at the tropopause have a steep -3 slope at synoptic scales, but transition to -5/3 at wavelengths of the order of 500-1,000 km [Nastrom, G.

Despite its simplicity, the model is consistent with a number of perplexing features in the observations and demonstrates that a complete theory for mesoscale dynamics must take temperature advection at boundaries into account.

This paper demonstrates, using a combination of new ARPES measurements and quantum Monte Carlo simulations, that the HEA is not simply the byproduct of matrix element effects, but rather represents a cross-over from a quasi-particle band at low binding <span class="hlt">energies</span> near the Fermi level to valence bands at higher binding <span class="hlt">energy</span>, assumed to be of strong oxygen character, in both hole- and electron-doped cuprates. While photoemission matrix elements clearly play a role in changing the aesthetic appearance of the band dispersion, i.e. the 'waterfall'-like behavior, they provide an inadequate description for the physics that underlies the strong band renormalization giving rise to the HEA. Model calculations of the single-band Hubbard Hamiltonian showcase the role played by correlations in the formation of the HEA and uncover significant differences in the HEA <span class="hlt">energy</span> scale for hole- and electron-doped cuprates. In addition, this approach properly captures the transfer of spectral weight accompanying both hole and electron doping in a correlated material and provides a unifying description of the HEA across both sides of the cuprate phase diagram.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://www.osti.gov/scitech/servlets/purl/902146','SCIGOV-STC'); return false;" href="http://www.osti.gov/scitech/servlets/purl/902146"><span id="translatedtitle">A universal high <span class="hlt">energy</span> <span class="hlt">anomaly</span> in angle resolved photoemissionspectra of high temperature superconductors -- possible evidence ofspinon and holon branches</span></a></p> <p><a target="_blank" href="http://www.osti.gov/scitech">SciTech Connect</a></p> <p>Graf, J.; Gweon, G.-H.; McElroy, K.; Zhou, S.Y.; Jozwiak, C.; Rotenberg, E.; Bill, A.; Sasagawa, T.; Eisaki, H.; Uchida, S.; Takagi,H.; Lee, D.-H.; Lanzara A.</p> <p>2006-12-19</p> <p>A universal high <span class="hlt">energy</span> <span class="hlt">anomaly</span> in the single particlespectral function is reported in three different families of hightemperature superconductors by using angle-resolved photoemissionspectroscopy.

P.; Thompson, A. F.</p> <p>2012-12-01</p> <p>Here, for the first time, we propose the concept of Ocean Convective Available <span class="hlt">Potential</span> <span class="hlt">Energy</span> (OCAPE), which is the maximum kinetic <span class="hlt">energy</span> (KE) per unit seawater mass achievable by ocean convection. OCAPE occurs through a different mechanism from atmospheric CAPE, and involves the interplay of temperature and salinity on the equation of state of seawater. The thermobaric effect, which arises because the thermal coefficient of expansion increases with depth, is an important ingredient of OCAPE. We develop an accurate algorithm to calculate the OCAPE for a given temperature and salinity profile. We then validate our calculation of OCAPE by comparing it with the conversion of OCAPE to KE in a 2-D numerical model. We propose that OCAPE is an important <span class="hlt">energy</span> source of ocean deep convection and contributes to deep water formation. OCAPE, like Atmospheric CAPE, can help predict deep convection and may also provide a useful constraint for modelling deep convection in ocean GCMs. We plot the global distribution of OCAPE using data from the World Ocean Atlas 2009 (WOA09) and see many important features. These include large values of OCAPE in the Labrador, Greenland, Weddell and Mediterranean Seas, which are consistent with our present observations and understanding, but also identify some new features like the OCAPE pattern in the Antarctic Circumpolar Current (ACC). We propose that the diagnosis of OCAPE can improve our understanding of global patterns of ocean convection and deep water formation as well as ocean stratification, the meridional overturning circulation and mixed layer processes. The background of this work is briefly introduced as below. Open-ocean deep convection can significantly modify water properties both at the ocean surface and throughout the water column (Gordon 1982). Open-ocean convection is also an important mechanism for Ocean Deep Water formation and the transport of heat, freshwater and nutrient (Marshall and Schott 1999). Open-ocean convection may arise through strong surface buoyancy fluxes (Schott et al. 1996), or by thermobaric instability (Akitomo 1999a, b). Ingersoll (2005) demonstrated that thermobaric-induced deep convection is due to the abrupt release of ocean <span class="hlt">potential</span> <span class="hlt">energy</span> into kinetic <span class="hlt">energy</span>. In atmospheric dynamics, Convective Available <span class="hlt">Potential</span> <span class="hlt">Energy</span> (CAPE) has long been an important thermodynamic variable (Arakawa and Schubert 1974) that has been used to forecast moist convection (Doswell and Rasmussen 1994) and to test the performance of GCMs (Ye et al. 1998). However, the development of a similar diagnostic in the ocean has received little attention.; World Ocean Convective Available <span class="hlt">Potential</span> <span class="hlt">Energy</span> distribution in North-Hemisphere Autumn (J/kg)</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://www.pubmedcentral.nih.gov/articlerender.fcgi?tool=pmcentrez&artid=4593964','PMC'); return false;" href="http://www.pubmedcentral.nih.gov/articlerender.fcgi?tool=pmcentrez&artid=4593964"><span id="translatedtitle">Resolving <span class="hlt">Anomalies</span> in Predicting Electrokinetic <span class="hlt">Energy</span> Conversion Efficiencies of Nanofluidic Devices</span></a></p> <p><a target="_blank" href="http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?DB=pmc">PubMed Central</a></p> <p>Majumder, Sagardip; Dhar, Jayabrata; Chakraborty, Suman</p> <p>2015-01-01</p> <p>We devise a new approach for capturing complex interfacial interactions over reduced length scales, towards predicting electrokinetic <span class="hlt">energy</span> conversion efficiencies of nanofluidic devices.

The predictions from our model are supported by reported experimental data, and are in excellent quantitative agreement with molecular dynamics simulations.

Electricity in Iceland is generated primarily from hydro- and geothermal sources, and adding wind <span class="hlt">energy</span> has so far not been considered practical or even necessary. However, wind <span class="hlt">energy</span> is becoming a more viable option, as opportunities for new hydro- or geothermal power installations become limited. In order to obtain an estimate of the wind <span class="hlt">energy</span> <span class="hlt">potential</span> of Iceland, a wind atlas has been developed as part of the joint Nordic project 'Improved Forecast of Wind, Waves and Icing' (IceWind). Downscaling simulations performed with the Weather Research and Forecasting (WRF) model were used to determine the large-scale wind <span class="hlt">energy</span> <span class="hlt">potential</span> of Iceland. Local wind speed distributions are represented by Weibull statistics. The shape parameter across Iceland varies between 1.2 and 3.6, with the lowest values indicative of near-exponential distributions at sheltered locations, and the highest values indicative of normal distributions at exposed locations in winter. Compared with summer, average power density in winter is increased throughout Iceland by a factor of 2.0 - 5.5. In any season, there are also considerable spatial differences in average wind power density. Relative to the average value within 10 km of the coast, power density across Iceland varies between 50 - 250%, excluding glaciers, or between 300 - 1500 W m-2 at 50 m above ground level in winter. At intermediate elevations of 500 - 1000 m above mean sea level, power density is independent of the distance to the coast. In addition to seasonal and spatial variability, differences in average wind speed and power density also exist for different wind directions. Along the coast in winter, power density of onshore winds is higher by 100 - 700 W m-2 than that of offshore winds. The regions with the highest average wind speeds are impractical for wind farms, due to the distances from road infrastructure and the power grid, as well as due to the harsh winter climate. However, even in easily accessible regions, wind <span class="hlt">energy</span> <span class="hlt">potential</span> in Iceland, as measured by annual average power density, is among the highest in Western Europe. Based on these results, 14 test sites were selected for more detailed analyses using the Wind Atlas Analysis and Application Program (WAsP).

The latter lies in a transitional region of the nuclear chart, and will be essential to consistently understand the evolution of fission properties from neutron-deficient mercury to heavy actinides.

It is increasing by about 15 cm yr{sup -1}. The other two <span class="hlt">anomalies</span> are perhaps less disturbing because of known sources of nongravitational acceleration. The first is an apparent slowing of the two Pioneer spacecraft as they exit the solar system in opposite directions. Some astronomers and physicists are convinced this effect is of concern, but many others are convinced it is produced by a nearly identical thermal emission from both spacecraft, in a direction away from the Sun, thereby producing acceleration toward the Sun. The fourth <span class="hlt">anomaly</span> is a measured increase in the eccentricity of the Moon's orbit. Here again, an increase is expected from tidal friction in both the Earth and Moon. However, there is a reported unexplained increase that is significant at the three-sigma level. It is produent to suspect that all four <span class="hlt">anomalies</span> have mundane explanations, or that one or more <span class="hlt">anomalies</span> are a result of systematic error. Yet they might eventually be explained by new physics. For example, a slightly modified theory of gravitation is not ruled out, perhaps analogous to Einstein's 1916 explanation for the excess precession of Mercury's perihelion.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://adsabs.harvard.edu/abs/2011PApGe.168.1851A','NASAADS'); return false;" href="http://adsabs.harvard.edu/abs/2011PApGe.168.1851A"><span id="translatedtitle">Detection of High-<span class="hlt">Potential</span> Oil and Gas Fields Using Normalized Full Gradient of Gravity <span class="hlt">Anomalies</span>: A Case Study in the Tabas Basin, Eastern Iran</span></a></p> <p><a target="_blank" href="http://adsabs.harvard.edu/abstract_service.html">NASA Astrophysics Data System (ADS)</a></p> <p>Aghajani, Hamid; Moradzadeh, Ali; Zeng, Hualin</p> <p>2011-10-01</p> <p>The normalized full gradient (NFG) represents the full gradient of the gravity <span class="hlt">anomaly</span> at a point divided by the average of the full gradient at the same point. The NFG minimum between two maxima in an NFG section or a closed minimum surrounded by closed maxima on an NFG map may indicate density-deficient <span class="hlt">anomalies</span> closely related to possible oil-gas reservoirs. On a cross-section, closed minima can be used to estimate the depth to centers of possible hydrocarbon reservoirs. The NFG map can also be used to locate oil-gas exploratory wells for estimation of the depth of possible reservoirs. The objective of this paper is to use two and three-dimensional (2D and 3D) NFG on gravity data of the Tabas basin in Yazd province, eastern Iran. A hypothetical model is first considered to explore the NFG characteristics and their relationship with the geometry of the model. The physical properties of the model are then studied to simplify the interpretation of real data. Finally 2D and 3D NFG models are developed for real gravity data to predict the location of any possible high <span class="hlt">potential</span> oil-gas reservoirs. The results obtained indicate two zones in the northern and central parts of the Tabas basin suitable for hydrocarbon prospecting. However, the favorable zone located in the middle of the basin in which anticline E is detected at a depth of 5-7 km is more important for the purpose of hydrocarbon exploration.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://hdl.handle.net/2060/19940015696','NASA-TRS'); return false;" href="http://hdl.handle.net/2060/19940015696"><span id="translatedtitle">Computed <span class="hlt">potential</span> <span class="hlt">energy</span> surfaces for chemical reactions</span></a></p> <p><a target="_blank" href="http://ntrs.nasa.gov/search.jsp">NASA Technical Reports Server (NTRS)</a></p> <p>Walch, Stephen P.; Levin, Eugene</p> <p>1993-01-01</p> <p>A new global <span class="hlt">potential</span> <span class="hlt">energy</span> surface (PES) is being generated for O(P-3) + H2 yields OH + H.

Estimates of the costs of transforming biomass into different fuels as well as a survey of government's role in a biomass <span class="hlt">energy</span> program are presented. The major findings are summarized below. (1) California's existing biomass resources are sufficient to provide only 20 percent of its future liquid fuel requirements. (2) Meeting the full transportation demand with biomass derived fuels will require the development of exotic biomass sources such as kelp farms and significant reductions in automobile travel in the State. (3) Under assumptions of moderate increases in gasoline prices and without major new government incentives, the cost of transforming biomass into transport fuels will be competitive with the price of gasoline on a Btu basis by the year 1990. (4) The environmental impacts of collecting most forms of biomass are beneficial and should reduce air pollution from agricultural burning and water pollution from feedlot and dairy farm runoff. Moreover, the collection of logging residues should improve timber stand productivity and the harvest of chaparral should reduce the risk of wildfire in the State.

One aspect of IRETHERM's research focuses on Ireland's radiothermal granites, where increased concentrations of radioelements provide elevated heat-production (HP), surface heat-flow (SHF) and subsurface temperatures. An understanding of the contribution of granites to the thermal field of Ireland is important to assessing the geothermal <span class="hlt">energy</span> <span class="hlt">potential</span> of this low-enthalpy setting. This study focuses on the Galway granite in western Ireland, and the Leinster and the buried Kentstown granites in eastern Ireland. Shallow (<250 m) boreholes were drilled into the exposed Caledonian Leinster and Galway granites as part of a 1980's geothermal project. These studies yielded HP = 2-3 μWm-3 and HF = 80 mWm-2 at the Sally Gap borehole in the Northern Units of the Leinster granite, to the SW of Dublin. In the Galway granite batholith, on the west coast of Ireland, the Costelloe-Murvey granite returned HP = 7 μWm-3 and HF = 77 mWm-2, measured at the Rossaveal borehole. The buried Kentstown granite, 35 km NW of Dublin, has an associated negative Bouguer <span class="hlt">anomaly</span> and was intersected by two mineral exploration boreholes at depths of 660 m and 490 m. Heat production is measured at 2.4 μWm-3 in core samples taken from the weathered top 30 m of the granite. The core of this study consists of a program of magnetotelluric (MT) and audio-magnetotelluric (AMT) data acquisition across the three granite bodies, over three fieldwork seasons. MT and AMT data were collected at 59 locations along two profiles over the Leinster granite. Preliminary results show that the northern units of the Leinster granite (40 km SW of Dublin) extend to depths of 2-5 km. Preliminary results from the southern profile suggest a greater thickness of granite to a depth of 6-9 km beneath the Tullow pluton, 75 km SW of Dublin. Over the Galway granite, MT and AMT data have been collected at a total of 75 sites (33 consist of only AMT data acquisition, with both MT and AMT recorded at the remaining 42). Preliminary results show a deep resistor extending to depths of 15-20 km beneath the central block, with the resistive upper layer extending to depths of 3.5-7 km west of the Shannawona fault, a major structure that cuts the batholith. MT and AMT data acquired along a profile at 22 locations over the Kentstown granite suggests that this buried granite is at a depth of 400 m beneath the centre of the gravity <span class="hlt">anomaly</span>. The MT and AMT data will be integrated with gravity and seismic refraction data (in the case of the Leinster granite) to identify deeply penetrating faults, which may provide conduits for hydrothermal fluids, and to produce a robust estimation of the volumetric extent of the granites, which is crucial in defining their geothermal <span class="hlt">energy</span> <span class="hlt">potential</span>. Thermal conductivity and geochemical data will be incorporated to constrain the heat contribution of granites to the Irish crust.</p> </li> </ol> <div class="pull-right"> <ul class="pagination"> <li><a href="#" onclick='return showDiv("page_1");'>«</a></li> <li><a href="#" onclick='return showDiv("page_3");'>3</a></li> <li><a href="#" onclick='return showDiv("page_4");'>4</a></li> <li class="active"><span>5</span></li> <li><a href="#" onclick='return showDiv("page_6");'>6</a></li> <li><a href="#" onclick='return showDiv("page_7");'>7</a></li> <li><a href="#" onclick='return showDiv("page_25");'>»</a></li> </ul> </div> </div><!-- col-sm-12 --> </div><!-- row --> </div><!-- page_5 --> <div id="page_6" class="hiddenDiv"> <div class="row"> <div class="col-sm-12"> <div class="pull-right"> <ul class="pagination"> <li><a href="#" onclick='return showDiv("page_1");'>«</a></li> <li><a href="#" onclick='return showDiv("page_4");'>4</a></li> <li><a href="#" onclick='return showDiv("page_5");'>5</a></li> <li class="active"><span>6</span></li> <li><a href="#" onclick='return showDiv("page_7");'>7</a></li> <li><a href="#" onclick='return showDiv("page_8");'>8</a></li> <li><a href="#" onclick='return showDiv("page_25");'>»</a></li> </ul> </div> </div> </div> <div class="row"> <div class="col-sm-12"> <ol class="result-class" start="101"> <li> <p><a target="_blank" onclick="trackOutboundLink('http://www.osti.gov/scitech/servlets/purl/139885','SCIGOV-STC'); return false;" href="http://www.osti.gov/scitech/servlets/purl/139885"><span id="translatedtitle">Theoretical studies of <span class="hlt">potential</span> <span class="hlt">energy</span> surfaces</span></a></p> <p><a target="_blank" href="http://www.osti.gov/scitech">SciTech Connect</a></p> <p>Harding, L.B.</p> <p>1993-12-01</p> <p>The goal of this program is to calculate accurate <span class="hlt">potential</span> <span class="hlt">energy</span> surfaces (PES) for both reactive and nonreactive systems.

Recently, models that utilize a multipole expansion located on a single site in the water molecule, or "molecular multipole models", have been shown to rival and even surpass site models with up to five sites in reproducing both the electrostatic <span class="hlt">potential</span> around a molecule and a variety of liquid state properties in simulations. However, despite decades of work using multipoles, confusion still remains about how to truncate the multipole expansions efficiently and accurately. This is particularly important when using molecular multipole expansions to describe water molecules in the liquid state, where the short-range interactions must be accurate, because the higher order multipoles of a water molecule are large. Here, truncation schemes designed for a recent efficient algorithm for multipoles in molecular dynamics simulations are assessed for how well they reproduce results for a simple three-site model of water when the multipole moments and Lennard-Jones parameters of that model are used. In addition, the multipole analysis indicates that site models that do not account for out-of-plane electron density overestimate the stability of a non-hydrogen-bonded conformation, leading to serious consequences for the simulated liquid.

However, significant to <span class="hlt">potentially</span> insurmountable technical issues must be resolved before gas hydrates can be considered a viable option for affordable supplies of natural gas. The combined information from Arctic gas hydrate studies shows that, in permafrost regions, gas hydrates may exist at subsurface depths ranging from about 130 to 2000 m. The presence of gas hydrates in offshore continental margins has been inferred mainly from anomalous seismic reflectors, known as bottom-simulating reflectors, that have been mapped at depths below the sea floor ranging from about 100 to 1100 m. Current estimates of the amount of gas in the world's marine and permafrost gas hydrate accumulations are in rough accord at about 20,000 trillion m3. Disagreements over fundamental issues such as the volume of gas stored within delineated gas hydrate accumulations and the concentration of gas hydrates within hydrate-bearing strata have demonstrated that we know little about gas hydrates. Recently, however, several countries, including Japan, India, and the United States, have launched ambitious national projects to further examine the resource <span class="hlt">potential</span> of gas hydrates. These projects may help answer key questions dealing with the properties of gas hydrate reservoirs, the design of production systems, and, most important, the costs and economics of gas hydrate production.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://hdl.handle.net/2060/19880020509','NASA-TRS'); return false;" href="http://hdl.handle.net/2060/19880020509"><span id="translatedtitle">Computed <span class="hlt">potential</span> <span class="hlt">energy</span> surfaces for chemical reactions</span></a></p> <p><a target="_blank" href="http://ntrs.nasa.gov/search.jsp">NASA Technical Reports Server (NTRS)</a></p> <p>Walch, Stephen P.</p> <p>1988-01-01</p> <p>The minimum <span class="hlt">energy</span> path for the addition of a hydrogen atom to N2 is characterized in CASSCF/CCI calculations using the (4s3p2d1f/3s2p1d) basis set, with additional single point calculations at the stationary points of the <span class="hlt">potential</span> <span class="hlt">energy</span> surface using the (5s4p3d2f/4s3p2d) basis set.

We show that the differential operators may efficiently be decomposed into an azimuthal and an isotropic part. The differential operators are even more simplified for a certain class of isotropic kernels. Secondly, the differential operators are applied to the well-known integrals of Newton, Abel-Poisson, Pizzetti and Hotine. In this way, 40 new integral formulas are derived.

Higher- resolution surveys than are possible with ship-based techniques and broader surveys than are practical with ROVs and manned submersibles are necessary for more thoroughly understanding hydrothermal systems and their impact on ocean ecosystems. Autonomous vehicles (AUVs), such as the WHOI Autonomous Benthic Explorer (ABE) can be programmed to conduct high-resolution surveys that systematically cover a broad area of seafloor. Brothers volcano, a hydrothermally active submarine caldera volcano located on the Kermadec arc northwest of New Zealand, was surveyed in July-August 2007 using ABE. Brothers caldera is ~3 km in diameter with a floor depth of 1850 m and walls that rise 290-530 m above the caldera floor. A dacite cone with a summit depth of ~1200 m sits within the caldera, partially merging with the southern caldera wall. Prior to the survey, active hydrothermal vents were known to be perched along the NW caldera wall and located at three sites on the cone. The enclosed caldera, presence of known vent fields with differing geochemical characteristics, and existence of at least one currently inactive site made Brothers volcano an ideal site for a high-resolution survey to explore in greater detail the mass, thermal and geochemical exchanges of hydrothermal systems. During our expedition, the caldera walls and dacite cone (~7 km2) were completely surveyed by ABE with 50-60 m trackline spacing at an altitude of 50 m above the seafloor. Hydrothermal plumes were mapped with ABE's integrated CTD (conductivity- temperature-depth) and sensors measuring optical backscatter (particle concentrations) and oxidation- reduction <span class="hlt">potential</span> (ORP; indicating the presence of reduced chemical species). This survey resulted in the first high-resolution map of temperature, particle and ORP <span class="hlt">anomalies</span> within a hydrothermally active submarine caldera. New details about the extent and structure of the known active vent fields were revealed, and a new area of active venting was discovered along the west caldera wall. Additionally, relationships between source vents, buoyant plumes, and neutrally buoyant regional plumes mapped using standard surface ship methods can be compared. Simultaneously acquired bathymetry and magnetic <span class="hlt">anomaly</span> data show correlations between the geomorphology of the caldera, magnetic alterations and patterns of past and present hydrothermal venting.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://adsabs.harvard.edu/abs/2013mss..confEWG10W','NASAADS'); return false;" href="http://adsabs.harvard.edu/abs/2013mss..confEWG10W"><span id="translatedtitle">An Accurate <span class="hlt">Potential</span> <span class="hlt">Energy</span> Surface for Methane</span></a></p> <p><a target="_blank" href="http://adsabs.harvard.edu/abstract_service.html">NASA Astrophysics Data System (ADS)</a></p> <p>Wang, Xiao-Gang; Carrington, Tucker, Jr.</p> <p>2013-06-01</p> <p>An accurate full dimensional methane <span class="hlt">potential</span> <span class="hlt">energy</span> surface (PES) will aid in assigning and understanding its complicated spectrum. Heretofore, there is no pure ab initio PES of methane on which rovibrational levels have errors less than one cm^{-1}. % In this work, we obtain an accurate methane PES by starting with the ab initio PES of Schwenke and Partridge [Spectrochim. Acta A {57}, 887 (2001)] and adjusting 5 of their parameters to reproduce 39 reliable vibrational levels of CH_4. This reduces the rmsd from 4.3 cm^{-1} to 0.4 cm^{-1}. %which include all vibrational levels up to the Octad polyad %and only 4 levels of the Tetradecad polyad Since not all of the Tetradecad levels are certain, only 4, those confirmed by direct experimental transitions, are included in the fit. The new PES ought therefore to aid in the ongoing analysis of the Tetradecad polyad. To further test the accuracy of the new PES, vibrational and rovibrational levels are computed for CH_4, CH_3D, CHD_3 and CH_2D_2 and are compared with the extensive experimental data. The errors are all within about one cm^{-1}. The fitting is made possible by a contracted-iterative method for computing vibrational levels in a product of contracted stretch and bend functions. The fitting process is efficient because these contracted basis functions are not changed during the fitting cycles, which greatly reduces the time (to about 3 hours) to compute a new set of vibrational levels when the PES is slightly changed.

H.; Schulte-Pelkum, V.</p> <p>2012-12-01</p> <p>The varied geologic history experienced by different regions of the Western United States invites a range of explanations for modern topography. We present a multi-disciplinary investigation of the geometry, sources and consequences of density variations responsible for current elevations. We make use of ~3000 acceptable velocity models (from Shen et al., 2012, submitted to JGR) based on joint inversion of surface wave dispersion curves and receiver functions at each of ~1000 stations. We attempt to calculate densities concordant with both modern topography and seismic wavespeeds. These models include both a thermal and a compositional component in the crust and purely thermal variation in the mantle. Topographic heterogeneity is due in nearly equal part to crustal and mantle buoyancy variations. The high elevation, relatively thick crust of the Rockies is both chemically and thermally buoyant, while the Basin and Range and Snake River Plain crust has high temperatures but chemically dense crust. This discrepancy accounts for ~2 km of relief between the two provinces. Mantle buoyancies are dichotomous, with the Wyoming Craton, Great Plains, and central Colorado Plateau underlain by material that is significantly denser than regions to the west. Therefore elevations of these regions are 1-2 km lower in elevation. We note that crustal or concentrated mantle melt is likely beneath the Cascades, Southern Rockies and Snake River Plain. Melt depletion of the Wyoming Craton lithosphere may also be reflected in velocity-topography relations. In turn, we calculate the gravitational <span class="hlt">potential</span> <span class="hlt">energy</span> (GPE) resulting from the density structures and find highly positive GPE (~3-5x1012 N/m <span class="hlt">anomaly</span>) in the actively extending northern and western Basin and Range. On the contrary, compressive deformation in the California Coast Ranges and the Yakima Fold Belt coincides with negative GPE <span class="hlt">anomalies</span> (~-3x1012 N/m).

Inelastic neutron groups were observed corresponding to measured excitation <span class="hlt">energies</span> of: 1115 ± 29, 1212 ± 24, 1307 ± 24, 1503 ± 33, 1778 ± 40, 2112 ± 40, 2224 ± 35, 2423 ± 39, 2593 ± 41 and 2810 ± 67 keV. The experimental results were interpreted in terms of spherical-optical-statistical and coupled-channels models. A successful description of the differential elastic scattering below 10 MeV and the total cross section in the range 0-20 MeV was achieved using the spherical optical model with <span class="hlt">energy</span>-dependent strengths and geometries. These <span class="hlt">energy</span> dependencies are large below approximately 7.0 MeV, but become smaller and similar to those reported for "global" <span class="hlt">potentials</span> at higher <span class="hlt">energies</span>. This change in the <span class="hlt">energy</span> dependence of the parameters, which occurs about 19 MeV above the Fermi <span class="hlt">energy</span>, was also seen in the analysis of the 209Bi data and probably marks the onset of the Fermi surface <span class="hlt">anomaly</span>.

B.</p> <p>2008-05-01</p> <p>In frontier areas of Alaska, <span class="hlt">potential</span>-field studies play an important role in characterizing the geologic structure of sedimentary basins having <span class="hlt">potential</span> for undiscovered oil and gas resources. Two such areas are the Yukon Flats basin in the east-central interior of Alaska, and the coastal plain of the Arctic National Wildlife Refuge (ANWR) in northeastern Alaska. The Yukon Flats basin is a <span class="hlt">potential</span> source of hydrocarbon resources for local consumption and possible export. Knowledge of the subsurface configuration of the basin is restricted to a few seismic reflection profiles covering a limited area and one well. The seismic profiles were reprocessed and reinterpreted in preparation for an assessment of the oil and gas resources of the basin. The assessment effort required knowledge of the basin configuration away from the seismic profiles, as well as an understanding of the nature of the underlying basement. To extend the interpretation of the basin thickness across the entire area of the basin, an iterative Jachens-Moring gravity inversion was performed on gridded quasi-isostatic residual gravity <span class="hlt">anomaly</span> data. The inversion was constrained to agree with the interpreted basement surface along the seismic profiles. In addition to the main sedimentary depocenter interpreted from the seismic data as having over 8 km of fill, the gravity inversion indicated a depocenter with over 7 km of fill in the Crooked Creek sub-basin. Results for the Crooked Creek sub-basin are consistent with magnetic and magnetotelluric modeling, but they await confirmation by drilling or seismic profiling. Whether hydrocarbon source rocks are present in the pre-Cenozoic basement beneath Yukon Flats is difficult to determine because extensive surficial deposits obscure the bedrock geology, and no deep boreholes penetrate basement. The color and texture patterns in a red-green-blue composite image consisting of reduced-to-the-pole aeromagnetic data (red), magnetic <span class="hlt">potential</span> (blue), and basement gravity (green) highlight domains with common geophysical characteristics and, by inference, lithology. The observed patterns suggest that much of the basin is underlain by Devonian to Jurassic oceanic rocks that probably have little or no <span class="hlt">potential</span> for hydrocarbon generation. The coastal plain surficial deposits in the northern part of ANWR conceal another frontier basin with hydrocarbon <span class="hlt">potential</span>. Proprietary aeromagnetic and gravity data were used, along with seismic reflection profiles, to construct a structural and stratigraphic model of this highly deformed sedimentary basin for use in an <span class="hlt">energy</span> resource assessment. Matched-filtering techniques were used to separate short-wavelength magnetic and gravity <span class="hlt">anomalies</span> attributed to sources near the top of the sedimentary section from longer-wavelength <span class="hlt">anomalies</span> attributed to deeper basin and basement sources. Models along the seismic reflection lines indicate that the primary sources of the short-wavelength <span class="hlt">anomalies</span> are folded and faulted sedimentary beds truncated at the Pleistocene erosion surface. In map view, the aeromagnetic and gravity <span class="hlt">anomalies</span> produced by the sedimentary units were used to identify possible structural trapping features and geometries, but they also indicated that these features may be significantly disrupted by faulting.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://www.osti.gov/scitech/biblio/5793302','SCIGOV-STC'); return false;" href="http://www.osti.gov/scitech/biblio/5793302"><span id="translatedtitle"><span class="hlt">Potential</span> production of <span class="hlt">energy</span> cane for fuel in the Caribbean</span></a></p> <p><a target="_blank" href="http://www.osti.gov/scitech">SciTech Connect</a></p> <p>Samuels, G.</p> <p>1984-12-01</p> <p>Sugarcane presents a tremendous <span class="hlt">potential</span> as a renewable <span class="hlt">energy</span> source for the non-oil producing countries of the Caribbean.

The coronary blood flow was measured by thermodilution techniques with sampling in the aorta and coronary sinus to measure O2 concentration, glucose, and plasma lactate and catecholamine levels. Parameters of LV function were calculated from data obtained from biplane left cineventriculography. During PEP, the ejection fraction increased from 0.48 +/- 0.8 to 0.62 +/- 0.22, the mean velocity of circumferential fibre shortening from 0.79 +/- 0.37 to 1.12 +/- 0.45 circ/s (p less than 0.001) and systolic work from 97 +/- 46 to 139 +/- 67 g/m2 (p less than 0.05).

PEP was associated with increased myocardial noradrenaline secretion (-3.1 +/- 31.5 ng/min under basal conditions to 30.2 +/- 42.8 ng/min, p less than 0.05). Therefore, the inotropic effect of PEP imposes a high metabolic demand and is associated with increased myocardial noradrenaline secretion.

The Moon has long been known to be slowly drifting farther from Earth due to tidal forces. The Lunar Laser Ranging Experiment (LLRE) indicates the Moon's semimajor axis increasing at 3.82 ± .07 cm/yr, anomalously high. If the Moon were today gaining angular momentum at this rate, it would have coincided with Earth less than 2 Gyr ago. Study of tidal rhythmites indicates a rate of 2.9 ± 0.6 cm/yr. Historical eclipse observations independently measure a recession rate of 2.82 ± .08 cm/yr. Detailed numerical simulation of lunar orbital evolution predicts 2.91 cm/yr. LLRE differs from three independent experiments by over12 sigma. A cosmology where speed of light c is related to time t by GM=tc^3 has been suggested to predict the redshifts of Type Ia supernovae, and a 4.507034% proportion of baryonic matter. If c were changing in the amount predicted, lunar orbital distance would appear to increase by an additional 0.935 cm/yr.

An ISHM system must detect <span class="hlt">anomalies</span>, identify causes of such <span class="hlt">anomalies</span>, predict future <span class="hlt">anomalies</span>, help identify consequences of <span class="hlt">anomalies</span> for example, suggested mitigation steps. The system should also provide users with appropriate navigation tools to facilitate the flow of information into and out of the ISHM system. Central to the ability of the ISHM to detect <span class="hlt">anomalies</span> is a clearly defined catalog of <span class="hlt">anomalies</span>. Further, this lexicon of <span class="hlt">anomalies</span> must be organized in ways that make it accessible to a suite of tools used to manage the data, information and knowledge (DIaK) associated with a system. In particular, it is critical to ensure that there is optimal mapping between target <span class="hlt">anomalies</span> and the algorithms associated with their detection. During the early development of our ISHM architecture and approach, it became clear that a lexicon of <span class="hlt">anomalies</span> would be important to the development of critical <span class="hlt">anomaly</span> detection algorithms. In our work in the rocket engine test environment at John C. Stennis Space Center, we have access to a repository of discrepancy reports (DRs) that are generated in response to squawks identified during post-test data analysis. The DR is the tool used to document <span class="hlt">anomalies</span> and the methods used to resolve the issue. These DRs have been generated for many different tests and for all test stands. The result is that they represent a comprehensive summary of the <span class="hlt">anomalies</span> associated with rocket engine testing. Fig. 1 illustrates some of the data that can be extracted from a DR. Such information includes affected transducer channels, narrative description of the observed <span class="hlt">anomaly</span>, and the steps used to correct the problem. The primary goal of the <span class="hlt">anomaly</span> lexicon development efforts we have undertaken is to create a lexicon that could be used in support of an associated health assessment database system (HADS) co-development effort. There are a number of significant byproducts of the <span class="hlt">anomaly</span> lexicon compilation effort. For example, (1) Allows determination of the frequency distribution of <span class="hlt">anomalies</span> to help identify those with the <span class="hlt">potential</span> for high return on investment if included in automated detection as part of an ISHM system, (2) Availability of a regular lexicon could provide the base <span class="hlt">anomaly</span> name choices to help maintain consistency in the DR collection process, and (3) Although developed for the rocket engine test environment, most of the <span class="hlt">anomalies</span> are not specific to rocket testing, and thus can be reused in other applications.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://www.eia.gov/renewable/archive/neaf0001.pdf','EIAPUBS'); return false;" href="http://www.eia.gov/renewable/archive/neaf0001.pdf"><span id="translatedtitle"><span class="hlt">Energy</span> Consumption and Renewable <span class="hlt">Energy</span> Development <span class="hlt">Potential</span> on Indian Lands</span></a></p> <p><a target="_blank" href="http://www.eia.doe.gov/reports/">EIA Publications</a></p> <p></p> <p>2000-01-01</p> <p>Includes information on the electricity use and needs of Indian households and tribes, the comparative electricity rates that Indian households are paying, and the <span class="hlt">potential</span> for renewable resources development of Indian lands.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://www.osti.gov/scitech/servlets/purl/1248749','SCIGOV-STC'); return false;" href="http://www.osti.gov/scitech/servlets/purl/1248749"><span id="translatedtitle">Bandwidth Study on <span class="hlt">Energy</span> Use and <span class="hlt">Potential</span> <span class="hlt">Energy</span> Saving Opportunities in U.S. Chemical Manufacturing</span></a></p> <p><a target="_blank" href="http://www.osti.gov/scitech">SciTech Connect</a></p> <p>Sabine Brueske, Caroline Kramer, Aaron Fisher</p> <p>2015-06-01</p> <p><span class="hlt">Energy</span> bandwidth studies of U.S. manufacturing sectors can serve as foundational references in framing the range (or bandwidth) of <span class="hlt">potential</span> <span class="hlt">energy</span> savings opportunities.

Perhaps the most disturbing is the fact that when a spacecraft on a flyby trajectory approaches the Earth within 2000 km or less, it often experiences a change in total orbital <span class="hlt">energy</span> per unit mass. Next, a secular change in the astronomical unit AU is definitely a concern. It is reportedly increasing by about 15 cm yr-1. The other two <span class="hlt">anomalies</span> are perhaps less disturbing because of known sources of nongravitational acceleration. The first is an apparent slowing of the two Pioneer spacecraft as they exit the solar system in opposite directions. Some astronomers and physicists, including us, are convinced this effect is of concern, but many others are convinced it is produced by a nearly identical thermal emission from both spacecraft, in a direction away from the Sun, thereby producing acceleration toward the Sun. The fourth <span class="hlt">anomaly</span> is a measured increase in the eccentricity of the Moon's orbit. Here again, an increase is expected from tidal friction in both the Earth and Moon. However, there is a reported unexplained increase that is significant at the three-sigma level. It is prudent to suspect that all four <span class="hlt">anomalies</span> have mundane explanations, or that one or more <span class="hlt">anomalies</span> are a result of systematic error. Yet they might eventually be explained by new physics. For example, a slightly modified theory of gravitation is not ruled out, perhaps analogous to Einstein's 1916 explanation for the excess precession of Mercury's perihelion.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://pubs.er.usgs.gov/publication/70140581','USGSPUBS'); return false;" href="http://pubs.er.usgs.gov/publication/70140581"><span id="translatedtitle">Exploratory and spatial data analysis (EDA-SDA) for determining regional background levels and <span class="hlt">anomalies</span> of <span class="hlt">potentially</span> toxic elements in soils from Catorce-Matehuala, Mexico</span></a></p> <p><a target="_blank" href="http://pubs.er.usgs.gov/pubs/index.jsp?view=adv">USGS Publications Warehouse</a></p> <p>Chiprés, J.A.; Castro-Larragoitia, J.; Monroy, M.G.</p> <p>2009-01-01</p> <p>The threshold between geochemical background and <span class="hlt">anomalies</span> can be influenced by the methodology selected for its estimation. Environmental evaluations, particularly those conducted in mineralized areas, must consider this when trying to determinate the natural geochemical status of a study area, quantifying human impacts, or establishing soil restoration values for contaminated sites. Some methods in environmental geochemistry incorporate the premise that <span class="hlt">anomalies</span> (natural or anthropogenic) and background data are characterized by their own probabilistic distributions. One of these methods uses exploratory data analysis (EDA) on regional geochemical data sets coupled with a geographic information system (GIS) to spatially understand the processes that influence the geochemical landscape in a technique that can be called a spatial data analysis (SDA). This EDA-SDA methodology was used to establish the regional background range from the area of Catorce-Matehuala in north-central Mexico. Probability plots of the data, particularly for those areas affected by human activities, show that the regional geochemical background population is composed of smaller subpopulations associated with factors such as soil type and parent material. This paper demonstrates that the EDA-SDA method offers more certainty in defining thresholds between geochemical background and <span class="hlt">anomaly</span> than a numeric technique, making it a useful tool for regional geochemical landscape analysis and environmental geochemistry studies.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://adsabs.harvard.edu/abs/2015JHEP...02..078A','NASAADS'); return false;" href="http://adsabs.harvard.edu/abs/2015JHEP...02..078A"><span id="translatedtitle">Lifshitz scale <span class="hlt">anomalies</span></span></a></p> <p><a target="_blank" href="http://adsabs.harvard.edu/abstract_service.html">NASA Astrophysics Data System (ADS)</a></p> <p>Arav, Igal; Chapman, Shira; Oz, Yaron</p> <p>2015-02-01</p> <p>We analyse scale <span class="hlt">anomalies</span> in Lifshitz field theories, formulated as the relative cohomology of the scaling operator with respect to foliation preserving diffeomorphisms.

The work performed by this "gravitational tectonics stress" must have formerly existed as gravitational <span class="hlt">potential</span> <span class="hlt">energy</span> contained in the stress-causing density structure. According to the elastic rebound theory (Reid, 1910), the <span class="hlt">energy</span> of earthquakes comes from an elastic strain field built up by fairly continuous elastic deformation in the period between events. For earthquakes resulting from gravitational tectonic stress, the elastic rebound theory requires the transfer of <span class="hlt">energy</span> from the gravitational <span class="hlt">potential</span> of the density structures into an elastic strain field prior to the event. An alternate theory involves partial gravitational collapse of the stress-causing density structures. The earthquake <span class="hlt">energy</span> comes directly from a net decrease in gravitational <span class="hlt">potential</span> <span class="hlt">energy</span>. The gravitational <span class="hlt">potential</span> <span class="hlt">energy</span> released at the time of the earthquake is split between the <span class="hlt">energy</span> released by the earthquake, including work done in the fault zone and an increase in stored elastic strain <span class="hlt">energy</span>.

Since direct measurements are often not feasible, indirect methods, e.g., (d ,p ) reactions, should be used. Those (d ,p ) reactions may be viewed as three-body reactions and described with Faddeev techniques. Purpose: Faddeev equations in momentum space have a long tradition of utilizing separable interactions in order to arrive at sets of coupled integral equations in one variable. Optical <span class="hlt">potentials</span> representing the effective interactions in the neutron (proton) nucleus subsystem are usually non-Hermitian as well as <span class="hlt">energy</span> dependent. <span class="hlt">Potential</span> matrix elements as well as transition matrix elements calculated with them must fulfill the reciprocity theorem. The purpose of this paper is to introduce a separable, <span class="hlt">energy</span>-dependent representation of complex, <span class="hlt">energy</span>-dependent optical <span class="hlt">potentials</span> that fulfill reciprocity exactly. Methods: Momentum space Lippmann-Schwinger integral equations are solved with standard techniques to obtain the form factors for the separable representation. Results: Starting from a separable, <span class="hlt">energy</span>-independent representation of global optical <span class="hlt">potentials</span> based on a generalization of the Ernst-Shakin-Thaler (EST) scheme, a further generalization is needed to take into account the <span class="hlt">energy</span> dependence. Applications to n +48Ca ,n +208Pb , and p +208Pb are investigated for <span class="hlt">energies</span> from 0 to 50 MeV with special emphasis on fulfilling reciprocity. Conclusions: We find that the <span class="hlt">energy</span>-dependent separable representation of complex, <span class="hlt">energy</span>-dependent phenomenological optical <span class="hlt">potentials</span> fulfills reciprocity exactly. In addition, taking into account the explicit <span class="hlt">energy</span> dependence slightly improves the description of the S matrix elements.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://ntrs.nasa.gov/search.jsp?R=19770035247&hterms=Potential+energy&qs=Ntx%3Dmode%2Bmatchall%26Ntk%3DAll%26N%3D0%26No%3D90%26Ntt%3DPotential%2Benergy','NASA-TRS'); return false;" href="http://ntrs.nasa.gov/search.jsp?R=19770035247&hterms=Potential+energy&qs=Ntx%3Dmode%2Bmatchall%26Ntk%3DAll%26N%3D0%26No%3D90%26Ntt%3DPotential%2Benergy"><span id="translatedtitle">A triangular element based on generalized <span class="hlt">potential</span> <span class="hlt">energy</span> concepts</span></a></p> <p><a target="_blank" href="http://ntrs.nasa.gov/search.jsp">NASA Technical Reports Server (NTRS)</a></p> <p>Thomas, G.

Eruptions occur where dykes propagate to the surface, with lava flows causing a major threat. When such eruption occur under ice, as is common in Iceland, they become explosive and often cause hazardous and destructive floods. Dykes have also been known to trigger explosive eruption when hot basaltic magma comes in contact with more developed volatile saturated magma. Such explosive eruptions pose a danger to both lives and property. At divergent plate boundaries new crust is formed primarily by dyke injections. These injections usually grow laterally away from a central volcano. Lateral growth of a dyke is expected to follow the minimum <span class="hlt">potential</span> <span class="hlt">energy</span> principle. Assuming a closed system, a dyke will tend to be emplaced such that it minimizes the total <span class="hlt">potential</span> <span class="hlt">energy</span>, ?T, given by: ?T = ?s + ?g (1) where ?s is the strain <span class="hlt">potential</span> and ?g the gravitational <span class="hlt">energy</span> <span class="hlt">potential</span>. Assuming that the elastic medium behaves linearly the strain <span class="hlt">potential</span> can be calculated by numerically integrating the strain <span class="hlt">energy</span> density over a large volume. If the dyke is assumed to be propagating at a constant depth with respect to sea level the gravitational <span class="hlt">potential</span> <span class="hlt">energy</span> can be turned into a two dimensional integral. We do this by integrating the predicted vertical displacements multiplied by the local topographic load above a reference surface and the acceleration of gravity. We approximate strain and stress due to plate movements and then consider strain changes induced by the dyke formation. Opening of a dyke is energetically favourable when it releases strain <span class="hlt">energy</span> built up at a divergent plate boundary, but once deviatoric stress in the crust adjacent to a segment is released it becomes favourable to propagate laterally. Dyke formation is associated with uplift on their flanks; the lower the topographic load over the flanks, the less <span class="hlt">energy</span> it costs. For any given location on a volcano, the strike of a new dyke segment will influence the strain and gravitational <span class="hlt">potential</span> <span class="hlt">energy</span> change in a different way. This type of model was applied to the more than 45 km long dyke formed in the Brarbunga volcanic system in Iceland in a rifting event in August 2014. Large observed changes in strike can be explained mostly by interplay of gravitational effects of topography and plate boundary strain. The model minimizing the total <span class="hlt">potential</span> <span class="hlt">energy</span> explains this propagation path. Our results suggest that by applying the total minimum <span class="hlt">potential</span> <span class="hlt">energy</span> principle we can forecast dyke propagation.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://adsabs.harvard.edu/abs/2014APS..MARJ33013H','NASAADS'); return false;" href="http://adsabs.harvard.edu/abs/2014APS..MARJ33013H"><span id="translatedtitle">Testing excited-state <span class="hlt">energy</span>-density functionals and <span class="hlt">potentials</span> with the ionization <span class="hlt">potential</span> theorem</span></a></p> <p><a target="_blank" href="http://adsabs.harvard.edu/abstract_service.html">NASA Astrophysics Data System (ADS)</a></p> <p>Harbola, Manoj; Myneni, Hemanadhan; Shamim, Md.</p> <p>2014-03-01</p> <p>The modified local spin density functional and the related local <span class="hlt">potential</span> for excited-states are tested by employing the ionization <span class="hlt">potential</span> theorem.

The calculations have been carried out by means of the very accurate and highly efficient method proposed and applied to H216O in a previous paper [Polyansky, Jensen, and Tennyson, J. Chem. Phys. 101, 7651 (1994)]. This previous work has been significantly improved by inclusion of additional terms in the analytical expression used to represent the <span class="hlt">potential</span> <span class="hlt">energy</span> surface. Previously, 1600 rotation-vibration term values for H216O were fitted with a standard deviation of 0.36 cm-1. With the extended model of the present work, this standard deviation could be improved to 0.25 cm-1. With the extended model and the new fitted <span class="hlt">potential</span> function we have calculated a data set comprising 3200 term values, all of which can be compared with experimentally derived values. The standard deviation for this data set is 0.6 cm-1.

The <span class="hlt">potential</span> <span class="hlt">energy</span> function obtained in the present work improves drastically the agreement with experiment for the highly excited local mode stretching states above 20 000 cm-1. For the vibrational band origins of these states, the highest of which is measured at 25 118 cm-1, our previous fitted <span class="hlt">potential</span> produced discrepancies of more than 100 cm-1. These deviations are reduced to less than 1 cm-1 by the <span class="hlt">potential</span> <span class="hlt">energy</span> function of the present work. We show that no significant improvement of the fit can be obtained by extending the analytical expression for the <span class="hlt">potential</span> <span class="hlt">energy</span> by further high-order terms. An analysis of the residuals shows that at the level of accuracy achieved, the major contribution to the error originates in the neglect of nonadiabatic correction terms in the Born-Oppenheimer kinetic <span class="hlt">energy</span> operator.

Yet there are substantial and important uncertainties about the <span class="hlt">potential</span> costs and supplies of wind that influence our ability to understand today the strategic role of wind power in the future. A detailed global assessment of onshore wind <span class="hlt">energy</span> <span class="hlt">potential</span> and its uncertainties will help decision-makers develop policies and strategies to meet <span class="hlt">energy</span> and environmental goals. In this study, we assess the technical and economic <span class="hlt">potential</span> of onshore wind <span class="hlt">energy</span> and its spatial distribution using reanalysis wind speed data from the National Centers for Environmental Modeling (Figure 1). The study focuses in particular in exploring a range of uncertainties that impact the economic <span class="hlt">potential</span> of wind power by constructing quantitative scenarios for eight key physical and economic parameters. We present quantification of the impact of uncertainties in these parameters, focusing on areas relevant to geoscience research (Figure 2). The amount of economic <span class="hlt">potential</span> of wind <span class="hlt">energy</span> depends strongly on several uncertain parameters such as wind speed, turbine cost, and land-suitability. The distribution of wind speed at fine temporal and spatial scales is a key parameter, but is not well quantified in many regions of the world. Reanalysis datasets with more accurate wind fields are a first step, along with computationally tractable downscaling methodologies. Another key assumption is land-suitability, which is the fraction of a particular land-cover type assumed to be available for wind farm development. There is currently little scientific basis for land-suitability assumptions. While some of the data needed for progress in these areas is readily available, such as high-resolution land-cover and terrain data, further advances are likely to require new methodologies and inter-disciplinary collaboration. We outline a number of areas where further research is needed to construct improved estimates of global wind <span class="hlt">energy</span> <span class="hlt">potential</span>.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://www.osti.gov/scitech/biblio/21028097','SCIGOV-STC'); return false;" href="http://www.osti.gov/scitech/biblio/21028097"><span id="translatedtitle">Optimizing <span class="hlt">potential</span> <span class="hlt">energy</span> functions for maximal intrinsic hyperpolarizability</span></a></p> <p><a target="_blank" href="http://www.osti.gov/scitech">SciTech Connect</a></p> <p>Zhou Juefei; Szafruga, Urszula B.; Kuzyk, Mark G.; Watkins, David S.</p> <p>2007-11-15</p> <p>We use numerical optimization to study the properties of (1) the class of one-dimensional <span class="hlt">potential</span> <span class="hlt">energy</span> functions and (2) systems of point nuclei in two dimensions that yield the largest intrinsic hyperpolarizabilities, which we find to be within 30% of the fundamental limit.

Furthermore, all optimized <span class="hlt">potential</span> <span class="hlt">energy</span> functions share common features such as (1) the value of the normalized transition dipole moment to the dominant state, which forces the hyperpolarizability to be dominated by only two excited states and (2) the <span class="hlt">energy</span> ratio between the two dominant states.

Each split gate defines a one-dimensional channel on a modulation-doped GaAs /AlGaAs heterostructure, through which the conductance is quantized. The yield of devices showing good quantization decreases rapidly as the length of the split gates increases. However, for the subset of devices showing good quantization, there is no correlation between the electrostatic length of the one-dimensional channel (estimated using a saddle-point model) and the gate length. The variation in electrostatic length and the one-dimensional subband spacing for devices of the same gate length exceeds the variation in the average values between devices of different lengths. There is a clear correlation between the curvature of the <span class="hlt">potential</span> barrier in the transport direction and the strength of the "0.7 <span class="hlt">anomaly</span>": the conductance value of the 0.7 <span class="hlt">anomaly</span> reduces as the barrier curvature becomes shallower.

An awareness of probable shortages of strategic materials has been maintained in these suggested programs.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://www.osti.gov/scitech/biblio/1001516','SCIGOV-STC'); return false;" href="http://www.osti.gov/scitech/biblio/1001516"><span id="translatedtitle">Reaction Path Optimization with Holonomic Constraints and Kinetic <span class="hlt">Energy</span> <span class="hlt">Potentials</span></span></a></p> <p><a target="_blank" href="http://www.osti.gov/scitech">SciTech Connect</a></p> <p>Brokaw, Jason B.; Haas, Kevin R.; Chu, Jhih-wei</p> <p>2009-08-11</p> <p>Two methods are developed to enhance the stability, efficiency, and robustness of reaction path optimization using a chain of replicas. First, distances between replicas are kept equal during path optimization via holonomic constraints. Finding a reaction path is, thus, transformed into a constrained optimization problem. This approach avoids force projections for finding minimum <span class="hlt">energy</span> paths (MEPs), and fast-converging schemes such as quasi-Newton methods can be readily applied. Second, we define a new objective function - the total Hamiltonian - for reaction path optimization, by combining the kinetic <span class="hlt">energy</span> <span class="hlt">potential</span> of each replica with its <span class="hlt">potential</span> <span class="hlt">energy</span> function. Minimizing the total Hamiltonian of a chain determines a minimum Hamiltonian path (MHP). If the distances between replicas are kept equal and a consistent force constant is used, then the kinetic <span class="hlt">energy</span> <span class="hlt">potentials</span> of all replicas have the same value. The MHP in this case is the most probable isokinetic path. Our results indicate that low-temperature kinetic <span class="hlt">energy</span> <span class="hlt">potentials</span> (<5 K) can be used to prevent the development of kinks during path optimization and can significantly reduce the required steps of minimization by 2-3 times without causing noticeable differences between a MHP and MEP. These methods are applied to three test cases, the C₇eq-to-Cax isomerization of an alanine dipeptide, the ⁴C₁- to-¹C₄ transition of an α-D-glucopyranose, and the helix-to-sheet transition of a GNNQQNY heptapeptide. By applying the methods developed in this work, convergence of reaction path optimization can be achieved for these complex transitions, involving full atomic details and a large number of replicas (>100). For the case of helix-to-sheet transition, we identify pathways whose <span class="hlt">energy</span> barriers are consistent with experimental measurements. Further, we develop a method based on the work <span class="hlt">energy</span> theorem to quantify the accuracy of reaction paths and to determine whether the atoms used to define a path are enough to provide quantitative estimation of <span class="hlt">energy</span> barriers.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://ntrs.nasa.gov/search.jsp?R=19850045155&hterms=Potential+energy&qs=Ntx%3Dmode%2Bmatchall%26Ntk%3DAll%26N%3D0%26No%3D70%26Ntt%3DPotential%2Benergy','NASA-TRS'); return false;" href="http://ntrs.nasa.gov/search.jsp?R=19850045155&hterms=Potential+energy&qs=Ntx%3Dmode%2Bmatchall%26Ntk%3DAll%26N%3D0%26No%3D70%26Ntt%3DPotential%2Benergy"><span id="translatedtitle">Reference pressure changes and available <span class="hlt">potential</span> <span class="hlt">energy</span> in isobaric coordinates</span></a></p> <p><a target="_blank" href="http://ntrs.nasa.gov/search.jsp">NASA Technical Reports Server (NTRS)</a></p> <p>Robertson, F.

In this paper, we introduce a pseudospectral Gaussian-based method that achieves accurate quantum dynamics using efficient, real-space sampling of the time-dependent basis set. As in other Gaussian basis methods, we begin with a basis set expansion using time-dependent Gaussian basis functions guided by classical mechanics. Unlike other Gaussian methods but characteristic of the pseudospectral and collocation methods, the basis set is tested with N Dirac delta functions, where N is the number of basis functions, rather than using the basis function as test functions. As a result, the integration for matrix elements is reduced to function evaluation. Pseudospectral Gaussian dynamics only requires O(N) <span class="hlt">potential</span> <span class="hlt">energy</span> calculations, in contrast to O(N(2)) evaluations in a variational calculation. The classical trajectories allow small basis sets to sample high-dimensional <span class="hlt">potentials</span>. Applications are made to diatomic oscillations in a Morse <span class="hlt">potential</span> and a generalized version of the Henon-Heiles <span class="hlt">potential</span> in two, four, and six dimensions. Comparisons are drawn to full analytical evaluation of <span class="hlt">potential</span> <span class="hlt">energy</span> integrals (variational) and the bra-ket averaged Taylor (BAT) expansion, an O(N) approximation used in Gaussian-based dynamics. In all cases, the pseudospectral Gaussian method is competitive with full variational calculations that require a global, analytical, and integrable <span class="hlt">potential</span> <span class="hlt">energy</span> surface. Additionally, the BAT breaks down when quantum mechanical coherence is particularly strong (i.e., barrier reflection in the Morse oscillator). The ability to obtain variational accuracy using only the <span class="hlt">potential</span> <span class="hlt">energy</span> at discrete points makes the pseudospectral Gaussian method a promising avenue for on-the-fly dynamics, where electronic structure calculations become computationally significant.

Erik E-mail: keeton@physics.rutgers.ed</p> <p>2010-02-01</p> <p>We examine the ability of gravitational lens time delays to reveal complex structure in lens <span class="hlt">potentials</span>. In a previous paper, we predicted how the time delay between the bright pair of images in a 'fold' lens scales with the image separation, for smooth lens <span class="hlt">potentials</span>. Here we show that the proportionality constant increases with the quadrupole moment of the lens <span class="hlt">potential</span>, and depends only weakly on the position of the source along the caustic. We use Monte Carlo simulations to determine the range of time delays that can be produced by realistic smooth lens models consisting of isothermal ellipsoid galaxies with tidal shear. We can then identify outliers as 'time delay <span class="hlt">anomalies</span>'. We find evidence for <span class="hlt">anomalies</span> in close image pairs in the cusp lenses RX J1131 - 1231 and B1422+231. The <span class="hlt">anomalies</span> in RX J1131 - 1231 provide strong evidence for substructure in the lens <span class="hlt">potential</span>, while at this point the apparent <span class="hlt">anomalies</span> in B1422+231 mainly indicate that the time delay measurements need to be improved. We also find evidence for time delay <span class="hlt">anomalies</span> in larger-separation image pairs in the fold lenses, B1608+656 and WFI 2033 - 4723, and the cusp lens RX J0911+0551. We suggest that these <span class="hlt">anomalies</span> are caused by some combination of substructure and a complex lens environment. Finally, to assist future monitoring campaigns we use our smooth models with shear to predict the time delays for all known four-image lenses.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://eric.ed.gov/?q=Unit+AND+System+AND+Physics+AND+learning&pg=3&id=ED190755','ERIC'); return false;" href="http://eric.ed.gov/?q=Unit+AND+System+AND+Physics+AND+learning&pg=3&id=ED190755"><span id="translatedtitle">Unified Technical Concepts.

This has pointed to the need for <span class="hlt">energy</span> and material efficiency, which would reduce air, water and thermal pollution, as well as waste production. Increasing <span class="hlt">energy</span> and material efficiency also have the benefits of increased employment, improved balance of imports and exports, increased security of <span class="hlt">energy</span> supply, and adopting environmentally advantageous <span class="hlt">energy</span> supply. A large <span class="hlt">potential</span> exists for <span class="hlt">energy</span> savings through <span class="hlt">energy</span> and material efficiency improvements. Technologies are not now, nor will they be, in the foreseeable future, the limiting factors with regard to continuing <span class="hlt">energy</span> efficiency improvements. There are serious barriers to <span class="hlt">energy</span> efficiency improvement, including unwillingness to invest, lack of available and accessible information, economic disincentives and organizational barriers. A wide range of policy instruments, as well as innovative approaches have been tried in some countries in order to achieve the desired <span class="hlt">energy</span> efficiency approaches. These include: regulation and guidelines; economic instruments and incentives; voluntary agreements and actions, information, education and training; and research, development and demonstration. An area that requires particular attention is that of improved international co-operation to develop policy instruments and technologies to meet the needs of developing countries. Material efficiency has not received the attention that it deserves. Consequently, there is a dearth of data on the qualities and quantities for final consumption, thus, making it difficult to formulate policies. Available data, however, suggest that there is a large <span class="hlt">potential</span> for improved use of many materials in industrialized countries.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://www.osti.gov/scitech/servlets/purl/935754','SCIGOV-STC'); return false;" href="http://www.osti.gov/scitech/servlets/purl/935754"><span id="translatedtitle">Global <span class="hlt">Potential</span> of <span class="hlt">Energy</span> Efficiency Standards and Labeling Programs</span></a></p> <p><a target="_blank" href="http://www.osti.gov/scitech">SciTech Connect</a></p> <p>McNeil, Michael A; McNeil, Michael A.; Letschert, Virginie; de la Rue du Can, Stephane</p> <p>2008-06-15</p> <p>This report estimates the global <span class="hlt">potential</span> reductions in greenhouse gas emissions by 2030 for <span class="hlt">energy</span> efficiency improvements associated with equipment (appliances, lighting, and HVAC) in buildings by means of <span class="hlt">energy</span> efficiency standards and labels (EES&L). A consensus has emerged among the world's scientists and many corporate and political leaders regarding the need to address the threat of climate change through emissions mitigation and adaptation. A further consensus has emerged that a central component of these strategies must be focused around <span class="hlt">energy</span>, which is the primary generator of greenhouse gas emissions. Two important questions result from this consensus: 'what kinds of policies encourage the appropriate transformation to <span class="hlt">energy</span> efficiency' and 'how much impact can these policies have'? This report aims to contribute to the dialogue surrounding these issues by considering the <span class="hlt">potential</span> impacts of a single policy type, applied on a global scale. The policy addressed in this report is <span class="hlt">Energy</span> Efficient Standards and Labeling (EES&L) for <span class="hlt">energy</span>-consuming equipment, which has now been implemented in over 60 countries. Mandatory <span class="hlt">energy</span> performance standards are important because they contribute positively to a nation's economy and provide relative certainty about the outcome (both timing and magnitudes). Labels also contribute positively to a nation's economy and importantly increase the awareness of the <span class="hlt">energy</span>-consuming public. Other policies not analyzed here (utility incentives, tax credits) are complimentary to standards and labels and also contribute in significant ways to reducing greenhouse gas emissions. We believe the analysis reported here to be the first systematic attempt to evaluate the <span class="hlt">potential</span> of savings from EES&L for all countries and for such a large set of products. The goal of the analysis is to provide an assessment that is sufficiently well-quantified and accurate to allow comparison and integration with other strategies under consideration.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://adsabs.harvard.edu/abs/2014AGUFMNH32A..07S','NASAADS'); return false;" href="http://adsabs.harvard.edu/abs/2014AGUFMNH32A..07S"><span id="translatedtitle">Understanding <span class="hlt">Potential</span> Climate Variability Impacts on the Offshore <span class="hlt">Energy</span> Industry</span></a></p> <p><a target="_blank" href="http://adsabs.harvard.edu/abstract_service.html">NASA Astrophysics Data System (ADS)</a></p> <p>Stear, J.</p> <p>2014-12-01</p> <p>Climate variability may have important implications for the offshore <span class="hlt">energy</span> industry.

To achieve these savings, the cumulative capital investment needed between 2010 and 2030 is about $440 billion, which translates to a 2-1/2 year simple payback period, or savings over the life of the measures that are nearly 3.5 times larger than the investment required (i.e., a benefit-cost ratio of 3.5).</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://www.osti.gov/scitech/biblio/21386616','SCIGOV-STC'); return false;" href="http://www.osti.gov/scitech/biblio/21386616"><span id="translatedtitle"><span class="hlt">Energy</span> dependence of the optical <span class="hlt">potential</span> of weakly and tightly bound nuclei as projectiles on a medium-mass target</span></a></p> <p><a target="_blank" href="http://www.osti.gov/scitech">SciTech Connect</a></p> <p>Figueira, J.

This dynamics is entitled NVU dynamics in analogy to standard <span class="hlt">energy</span>-conserving Newtonian NVE dynamics. In the first two papers [T. S. Ingebrigtsen, S. Toxvaerd, O. J. Heilmann, T. B. Schrøder, and J. C. Dyre, J. Chem. Phys. 135, 104101 (2011), 10.1063/1.3623585; T. S. Ingebrigtsen, S. Toxvaerd, T. B. Schrøder, and J. C. Dyre, J. Chem. Phys. 135, 104102 (2011), 10.1063/1.3623586], a numerical algorithm for simulating geodesic motion of atomic systems was developed and tested against standard algorithms. The conclusion was that the NVU algorithm has the same desirable properties as the Verlet algorithm for Newtonian NVE dynamics, i.e., it is time-reversible and symplectic. Additionally, it was concluded that NVU dynamics becomes equivalent to NVE dynamics in the thermodynamic limit. In this paper, the NVU algorithm for atomic systems is extended to be able to simulate the geodesic motion of molecules at constant <span class="hlt">potential</span> <span class="hlt">energy</span>. We derive an algorithm for simulating rigid bonds and test this algorithm on three different systems: an asymmetric dumbbell model, Lewis-Wahnström o-terphenyl (OTP) and rigid SPC/E water. The rigid bonds introduce additional constraints beyond that of constant <span class="hlt">potential</span> <span class="hlt">energy</span> for atomic systems. The rigid-bond NVU algorithm conserves <span class="hlt">potential</span> <span class="hlt">energy</span>, bond lengths, and step length for indefinitely long runs. The quantities probed in simulations give results identical to those of Nosé-Hoover NVT dynamics. Since Nosé-Hoover NVT dynamics is known to give results equivalent to those of NVE dynamics, the latter results show that NVU dynamics becomes equivalent to NVE dynamics in the thermodynamic limit also for molecular systems.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://adsabs.harvard.edu/abs/2016JHEP...03..077N','NASAADS'); return false;" href="http://adsabs.harvard.edu/abs/2016JHEP...03..077N"><span id="translatedtitle"><span class="hlt">Anomalies</span> and entanglement entropy</span></a></p> <p><a target="_blank" href="http://adsabs.harvard.edu/abstract_service.html">NASA Astrophysics Data System (ADS)</a></p> <p>Nishioka, Tatsuma; Yarom, Amos</p> <p>2016-03-01</p> <p>We initiate a systematic study of entanglement and Rényi entropies in the presence of gauge and gravitational <span class="hlt">anomalies</span> in even-dimensional quantum field theories.

A sensitivity analysis of eight key parameters is presented. Wind <span class="hlt">potential</span> is sensitive to a number of input parameters, particularly wind speed (varying by -70% to +450% at less than 9 cents/kWh), land suitability (by -55% to +25%), turbine density (by -60% to +80%), and cost and financing options (by -20% to +200%), many of which have important policy implications. As a result of sensitivities studied here we suggest that further research intended to inform wind supply curve development focus not purely on physical science, such as better resolved wind maps, but also on these less well-defined factors, such as land-suitability, that will also have an impact on the long-term role of wind power.

Lymphatic malformations likely arise through anomalous embryogenesis of the lymphatic system. Analysis of clinical, imaging, histologic, and hematologic features is often needed to reach a diagnosis. Aspiration of fluid collections can readily define fluid as chylous or not. The presence of chyle indicates dysfunction at the mesenteric or retroperitoneal level or above the cisterna chyli due to reflux. The imaging patterns of generalized lymphatic <span class="hlt">anomaly</span> (GLA) and Gorham-Stout disease have been segregated with distinctive bone lesions and peri-osseous features. More aggressive histology (spindled lymphatic endothelial cells), clinical progression, hemorrhage, or moderate hematologic changes should raise suspicion for kaposiform lymphangiomatosis. Biopsy may be needed for diagnosis, though avoidance of rib biopsy is advised to prevent iatrogenic chronic pleural effusion. Lymphangiography can visualize the anatomy and function of the lymphatic system and may identify dysfunction of the thoracic duct in central conducting lymphatic <span class="hlt">anomalies</span>.

V.</p> <p>2012-05-20</p> <p>At the Brookhaven National Laboratory, a physics program, motivated by the search of the QCD phase transition critical point, requires operation of the Relativistic Heavy Ion Collider (RHIC) with heavy ions at very low beam <span class="hlt">energies</span> corresponding to 2.5-20 GeV/n. Several physics runs were already successfully performed at these low <span class="hlt">energies</span>. However, the luminosity is very low at lowest <span class="hlt">energies</span> of interest (< 10 GeV/n) limited by the intra-beam scattering and space-charge, as well as by machine nonlinearities. At these low <span class="hlt">energies</span>, electron cooling could be very effective in counteracting luminosity degradation due to the IBS, while it is less effective against other limitations. Overall <span class="hlt">potential</span> luminosity improvement for low-<span class="hlt">energy</span> RHIC operation from cooling is summarized for various <span class="hlt">energies</span>, taking into account all these limitations as well as beam lifetime measured during the low-<span class="hlt">energy</span> RHIC runs.

Several methods for determining savings were examined, including existing programs, surveys, savings calculators, and economic simulation. Each method has advantages and disadvantages, trading off between detail of information, accuracy of results, and scope. This paper concentrated on using economic simulation (the NEMS model (EIA 2000a)) to determine market <span class="hlt">potential</span> for <span class="hlt">energy</span> savings for the residential and commercial sectors. The results of surveys were used to calculate the economic <span class="hlt">potential</span> for savings in the industrial sector. The NEMS model is used by the <span class="hlt">Energy</span> Information Administration to calculate twenty-year projections of <span class="hlt">energy</span> use for every region of the country. The results of the Annual <span class="hlt">Energy</span> Outlook 2000 were used as the Base case (EIA 1999a). Two alternative cases were created to simulate <span class="hlt">energy</span> savings policies. Voluntary, market-related programs were simulated by lowering the effective discount rates that end-users use when making decisions on equipment purchases. Standards programs in the residential sector were simulated by eliminating the availability of low efficiency equipment in future years. The parameters for these programs were based on the Moderate scenario from the DOE Clean <span class="hlt">Energy</span> Futures study (Interlaboratory Working Group 2000), which assumed increased concern by society on <span class="hlt">energy</span> efficiency but not to the point of fiscal policies such as taxes or direct subsidies. The study only considered a subset of the various programs, policies, and technologies that could reduce <span class="hlt">energy</span> use. The major end-uses in the residential sector affected by the policies were space cooling (20% savings by 2020) and water heating (14% savings by 2020.) Figure S-1 shows the space cooling savings when voluntary programs and minimum efficiency standards were implemented. Refrigerators, freezers, and clothes dryers saw slight improvements. The study did not involve changes to the building shell (e.g., increased insulation) or residential lighting improvements. Nevertheless, the residential sector's market <span class="hlt">potential</span> for electrical <span class="hlt">energy</span> savings was calculated to be 5.3% of expected electrical use, representing 850 GWh by 2020. Natural gas savings could be 2.4% of expected gas use, representing 2.1 trillion Btus. Using expected prices for <span class="hlt">energy</span> in that year, these represent savings of $47 million and $12 million per year. In the commercial sector, the study only considered voluntary market-based policies for some of the technologies. The most notable savings were in ventilation (12% savings by 2020), lighting (12% savings), refrigeration (7% savings), water heating (6% savings), and space heating (5% savings by 2020). The commercial sector's market <span class="hlt">potential</span> for electrical <span class="hlt">energy</span> savings based on the programs modeled was calculated to be 5.1% of its total expected electrical use, representing 605 GWh of power by 2020. Natural gas savings were 2.3 trillion Btu, 3.7% of use. Using the same prices as the residential sector (5.5{cents}/kWh and $5.74/MBtu), the savings represent $33 million and $13 million per year, respectively.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://adsabs.harvard.edu/abs/2009EGUGA..11.7261V','NASAADS'); return false;" href="http://adsabs.harvard.edu/abs/2009EGUGA..11.7261V"><span id="translatedtitle">The <span class="hlt">potential</span> impact of hydrogen <span class="hlt">energy</span> use on the atmosphere</span></a></p> <p><a target="_blank" href="http://adsabs.harvard.edu/abstract_service.html">NASA Astrophysics Data System (ADS)</a></p> <p>van Ruijven, B.

One possible option is a transition towards a hydrogen-based <span class="hlt">energy</span> system. The <span class="hlt">potential</span> impact of such hydrogen economy on atmospheric emissions is highly uncertain. On the one hand, application of hydrogen in clean fuel cells reduces emissions of local air pollutants, like SOx and NOx. On the other hand, emissions of hydrogen from system leakages are expected to change the atmospheric concentrations and behaviour (see also Price et al., 2007; Sanderson et al., 2003; Schultz et al., 2003; Tromp et al., 2003). The uncertainty arises from several sources: the expected use of hydrogen, the intensity of leakages and emissions, and the atmospheric chemical behaviour of hydrogen. Existing studies to the <span class="hlt">potential</span> impacts of a hydrogen economy on the atmosphere mostly use hydrogen emission scenarios that are based on simple assumptions. This research combines two different modelling efforts to explore the range of impacts of hydrogen on atmospheric chemistry. First, the <span class="hlt">potential</span> role of hydrogen in the global <span class="hlt">energy</span> system and the related emissions of hydrogen and other air pollutants are derived from the global <span class="hlt">energy</span> system simulation model TIMER (van Vuuren, 2007). A set of dedicated scenarios on hydrogen technology development explores the most pessimistic and optimistic cases for hydrogen deployment (van Ruijven et al., 2008; van Ruijven et al., 2007). These scenarios are combined with different assumptions on hydrogen emission factors. Second, the emissions from the TIMER model are linked to the NCAR atmospheric model (Lamarque et al., 2005; Lamarque et al., 2008), in order to determine the impacts on atmospheric chemistry. By combining an <span class="hlt">energy</span> system model and an atmospheric model, we are able to consistently explore the boundaries of both hydrogen use, emissions and impacts on atmospheric chemistry.

M.</p> <p>2010-12-01</p> <p>Tidal streams are high velocity sea currents created by periodic horizontal movement of the tides, often magnified by local topographical features such as headlands, inlets to inland lagoons, and straits. Tidal stream <span class="hlt">energy</span> extraction is derived from the kinetic <span class="hlt">energy</span> of the moving flow; analogous to the way a wind turbine operates in air, and as such differs from tidal barrages, which relies on providing a head of water for <span class="hlt">energy</span> extraction. With the constantly increasing effort in promoting alternative <span class="hlt">energy</span>, tidal streams have become promising <span class="hlt">energy</span> sources due to their continuous, predictable and concentrated characteristics. However, the present lack of a full spatial-temporal assessment of tidal currents for the U.S. coastline down to the scale of individual devices is a barrier to the comprehensive development of tidal current <span class="hlt">energy</span> technology. A methodology for creating a national database of tidal stream <span class="hlt">energy</span> <span class="hlt">potential</span>, as well as a GIS tool usable by industry in order to accelerate the market for tidal <span class="hlt">energy</span> conversion technology has been developed. The tidal flows are simulated using the Regional Ocean Modeling System (ROMS). The model is calibrated and validated using observations and tidal predictions. The calibration includes adjustments to model parameters such as bottom friction coefficient, changed land/water masks, or increased grid resolutions. A systematic validation process has been developed after defining various parameters to quantify the validation results. In order to determine the total tidal stream power resource, a common method frequently proposed is to estimate it as a fraction of the total kinetic <span class="hlt">energy</span> flux passing through a vertical section; however, this now has been shown to generally underestimate the total available resource. The total tidal <span class="hlt">energy</span> flux includes not just the kinetic <span class="hlt">energy</span> but also the <span class="hlt">energy</span> flux due to the work done by the pressure force associated with the tidal motion on the water column as well, which is frequently an order of magnitude larger. The numerical model provides the time series on a sufficiently high enough spatial resolution to utilize both the currents and mean water level (MWL) to compute the total <span class="hlt">energy</span> flux entering estuary. The time variation of the available power for a few different estuaries will be evaluated and compared to estimates based on constant flow properties.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://www.osti.gov/scitech/biblio/6616562','SCIGOV-STC'); return false;" href="http://www.osti.gov/scitech/biblio/6616562"><span id="translatedtitle">Mashreq Arab interconnected power system <span class="hlt">potential</span> for economic <span class="hlt">energy</span> trading</span></a></p> <p><a target="_blank" href="http://www.osti.gov/scitech">SciTech Connect</a></p> <p>Al-Shehri, A.M.; El-Amin, I.M.; Opoku, G.; Al-Baiyat, S.A.; Zedan, F.M.</p> <p>1994-12-01</p> <p>The Mashreq Arab countries covered in this study are Bahrain, Egypt, Jordan, Lebanon, Oman, Qatar, Saudi Arabia, Syria, the United Arab Emirates, and Yemen. A feasibility study for the interconnection of the electrical networks of the Mashreq Arab countries, sponsored by the Arab Fund, was completed in June 1992. Each country is served by one utility except Saudi Arabia, which is served by four major utilities and some smaller utilities serving remote towns and small load centers. The major utilities are the Saudi consolidated electric Company in the Eastern Province (SCECO East), SCECO Center, SCECO West, and SCECO South. These are the ones considered in this study. The Mashreq Arab region has a considerable mix of <span class="hlt">energy</span> resources. Egypt and Syria have some limited amounts of hydropower resources, and the Arabian Gulf region is abundant in fossil fuel reserves. Owing to the differences in <span class="hlt">energy</span> production costs, a <span class="hlt">potential</span> exists for substantial <span class="hlt">energy</span> trading between electric utilities in the region.

The basis, assumptions, and methodologies on which this <span class="hlt">energy</span> trading study is based relate to the results and conclusions arising out of the previous study, power plant characteristics and costs, assumptions on economic parameters, rules for economy <span class="hlt">energy</span> exchange, etc. This paper presents the basis, methodology, and major findings of the study.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://www.osti.gov/scitech/servlets/purl/986540','SCIGOV-STC'); return false;" href="http://www.osti.gov/scitech/servlets/purl/986540"><span id="translatedtitle">Data Network Equipment <span class="hlt">Energy</span> Use and Savings <span class="hlt">Potential</span> in Buildings</span></a></p> <p><a target="_blank" href="http://www.osti.gov/scitech">SciTech Connect</a></p> <p>Lanzisera, Steven; Nordman, Bruce; Brown, Richard E.</p> <p>2010-06-09</p> <p>Network connectivity has become nearly ubiquitous, and the <span class="hlt">energy</span> use of the equipment required for this connectivity is growing. Network equipment consists of devices that primarily switch and route Internet Protocol (IP) packets from a source to a destination, and this category specifically excludes edge devices like PCs, servers and other sources and sinks of IP traffic. This paper presents the results of a study of network equipment <span class="hlt">energy</span> use and includes case studies of networks in a campus, a medium commercial building, and a typical home. The total <span class="hlt">energy</span> use of network equipment is the product of the stock of equipment in use, the power of each device, and their usage patterns. This information was gathered from market research reports, broadband market penetration studies, field metering, and interviews with network administrators and service providers. We estimate that network equipment in the USA used 18 TWh, or about 1percent of building electricity, in 2008 and that consumption is expected to grow at roughly 6percent per year to 23 TWh in 2012; world usage in 2008 was 51 TWh. This study shows that office building network switches and residential equipment are the two largest categories of <span class="hlt">energy</span> use consuming 40percent and 30percent of the total respectively. We estimate <span class="hlt">potential</span> <span class="hlt">energy</span> savings for different scenarios using forecasts of equipment stock and <span class="hlt">energy</span> use, and savings estimates range from 20percent to 50percent based on full market penetration of efficient technologies.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://adsabs.harvard.edu/abs/2007SPIE.6414E..0DB','NASAADS'); return false;" href="http://adsabs.harvard.edu/abs/2007SPIE.6414E..0DB"><span id="translatedtitle"><span class="hlt">Potential</span> system efficiencies for MEMS vibration <span class="hlt">energy</span> harvesting</span></a></p> <p><a target="_blank" href="http://adsabs.harvard.edu/abstract_service.html">NASA Astrophysics Data System (ADS)</a></p> <p>Behrens, S.</p> <p>2007-01-01</p> <p>Reliable power sources are needed for portable micro-electromechanical systems (MEMS) devices such as wireless automobile tire pressure sensors.

Existing vibration <span class="hlt">energy</span> harvesting systems use either a piezoelectric or an electromagnetic transducer to convert vibrations into electrical <span class="hlt">energy</span>. This electrical <span class="hlt">energy</span> is then conditioned using a passive rectifier dc-dc converter circuit. Such vibration harvesting techniques have focused on optimising circuit efficiency and, hence, have ignored the system efficiency i.e. mechanical-to-electrical efficiency. Results obtained in the laboratory can be extrapolated to predict <span class="hlt">potential</span> system efficiencies for MEMS vibration <span class="hlt">energy</span> harvesting systems. Results to date, using a standard speaker as the electromagnetic transducer, have demonstrated system efficiencies of greater than 14%. Initial estimates suggest a MEMS system efficiency of more than 80% could be achieved with a high performance transducer.

Perhaps the most disturbing is the fact that when a spacecraft on a flyby trajectory approaches the Earth within 2000 km or less, it experiences a gain in total orbital <span class="hlt">energy</span> per unit mass (Anderson et al., Phys. Rev. Lett. 100, 091102). This amounts to a net velocity increase of 13.5 mm/s for the NEAR spacecraft at a closest approach of 539 km, 3.9 mm/s for the Galileo spacecraft at 960 km, and 1.8 mm/s for the Rosetta spacecraft at 1956 km. Next, I suggest the change in the astronomical unit AU is definitely a concern. It is increasing by about 15 cm/yr (Krasinsky and Brumberg, Celes. Mech. & Dynam. Astron. 90, 267). The other two <span class="hlt">anomalies</span> are perhaps less disturbing because of known sources of nongravitational acceleration. The first is an apparent slowing of the two Pioneer spacecraft as they exit the solar system in opposite directions (Anderson et al., Phys. Rev. D 65, 082004). Some, including me, are convinced this effect is of concern, but many are convinced it is produced by a nearly identical thermal emission from both spacecraft, in a direction away from the Sun, thereby producing acceleration toward the Sun. The fourth <span class="hlt">anomaly</span> is a measured increase in the eccentricity of the Moon's orbit. Here again, an increase is expected from tidal friction in both the Earth and Moon. However, there is a reported increase that is about three times larger than expected (J. G. Williams, DDA/AAS Brouwer Award Lecture, Halifax, Nova Scotia 2006). We suspect that all four <span class="hlt">anomalies</span> have mundane explanations. However, the possibility that they will be explained by a new theory of gravitation is not ruled out, perhaps analogous to Einstein's 1916 explanation of the excess precession of Mercury's perihelion.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://www.osti.gov/scitech/biblio/1051195','SCIGOV-STC'); return false;" href="http://www.osti.gov/scitech/biblio/1051195"><span id="translatedtitle">Evaluation of Global Onshore Wind <span class="hlt">Energy</span> <span class="hlt">Potential</span> and Generation Costs</span></a></p> <p><a target="_blank" href="http://www.osti.gov/scitech">SciTech Connect</a></p> <p>Zhou, Yuyu; Luckow, Patrick; Smith, Steven J.; Clarke, Leon E.</p> <p>2012-06-20</p> <p>In this study, we develop an updated global estimate of onshore wind <span class="hlt">energy</span> <span class="hlt">potential</span> using reanalysis wind speed data, along with updated wind turbine technology performance and cost assumptions as well as explicit consideration of transmission distance in the calculation of transmission costs. We find that wind has the <span class="hlt">potential</span> to supply a significant portion of world <span class="hlt">energy</span> needs, although this <span class="hlt">potential</span> varies substantially by region as well as with assumptions such as on what types of land can be used to site wind farms. Total global wind <span class="hlt">potential</span> under central assumptions is estimated to be approximately 89 petawatt hours per year at less than 9 cents/kWh with substantial regional variations. One limitation of global wind analyses is that the resolution of current global wind speed reanalysis data can result in an underestimate of high wind areas. A sensitivity analysis of eight key parameters is presented. Wind <span class="hlt">potential</span> is sensitive to a number of input parameters, particularly those related to land suitability and turbine density as well as cost and financing assumptions which have important policy implications. Transmission cost has a relatively small impact on total wind costs, changing the <span class="hlt">potential</span> at a given cost by 20-30%. As a result of sensitivities studied here we suggest that further research intended to inform wind supply curve development focus not purely on physical science, such as better resolved wind maps, but also on these less well-defined factors, such as land-suitability, that will also have an impact on the long-term role of wind power.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://www.ncbi.nlm.nih.gov/pubmed/17677447','PUBMED'); return false;" href="http://www.ncbi.nlm.nih.gov/pubmed/17677447"><span id="translatedtitle">Characterization of the <span class="hlt">potential</span> <span class="hlt">energy</span> landscape of an antiplasticized polymer.</span></a></p> <p><a target="_blank" href="http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?DB=pubmed">PubMed</a></p> <p>Riggleman, Robert A; Douglas, Jack F; de Pablo, Juan J</p> <p>2007-07-01</p> <p>The nature of the individual transitions on the <span class="hlt">potential</span> <span class="hlt">energy</span> landscape (PEL) associated with particle motion are directly examined for model fragile glass-forming polymer melts, and the results are compared to those of an antiplasticized polymer system. In previous work, we established that the addition of antiplasticizer reduces the fragility of glass formation so that the antiplasticized material is a stronger glass former. In the present work, we find that the antiplasticizing molecules reduce the <span class="hlt">energy</span> barriers for relaxation compared to the pure polymer, implying that the antiplasticized system has smaller barriers to overcome in order to explore its configuration space. We examine the cooperativity of segmental motion in these bulk fluids and find that more extensive stringlike collective motion enables the system to overcome larger <span class="hlt">potential</span> <span class="hlt">energy</span> barriers, in qualitative agreement with both the Stillinger-Weber and Adam-Gibbs views of glass formation. Notably, the stringlike collective motion identified by our PEL analysis corresponds to incremental displacements that occur within larger-scale stringlike particle displacement processes associated with PEL metabasin transitions that mediate structural relaxation. These "substrings" nonetheless seem to exhibit changes in relative size with antiplasticization similar to those observed in "superstrings" that arise at elevated temperatures. We also study the effects of confinement on the <span class="hlt">energy</span> barriers in each system. Film confinement makes the <span class="hlt">energy</span> barriers substantially smaller in the pure polymer, while it has little effect on the <span class="hlt">energy</span> barriers in the antiplasticized system. This observation is qualitatively consistent with our previous studies of stringlike motion in these fluids at higher temperatures and with recent experimental measurements by Torkelson and co-workers.

Among the leaders in the alternative <span class="hlt">energy</span> sector is wind power, which is now one of the largest sources of new power generation in the U.S. creating jobs and revenue for rural communities while powering our economy with an emissions-free source of <span class="hlt">energy</span>. In 2006, wind turbines capable of generating more than 2,400 megawatts of electricity were installed in the U.S. and by 2007 this number had risen to 3,000 megawatts. The U.S. generated 31 billion kilowatt-hours of wind power in 2007, which is enough electricity to power the equivalent of nearly 3 million average homes. It is estimated that generating the same amount of electricity would require burning 16 million tons of coal or 50 million barrels of oil. This study examines the wind power <span class="hlt">potential</span> of sites near populated areas in Florida and California to determine the practicability of installing wind turbines at these locations. A GIS was developed in order to conduct a spatial analysis of these sites based on mean annual wind speed measured in meters per second and wind power density ratings measured in watts per square meter. The analysis indicates that coastal areas of Cocoa Beach, Key West, Hollywood, and West Palm Beach, respectively, possess the greatest <span class="hlt">potential</span> for wind <span class="hlt">energy</span> in Florida with mean annual wind speeds of 4.9 m/s and average wind power density ratings of 171 w/m2 peaking at Cocoa Beach followed by wind speeds of 4.64 m/s and wind power ratings of 115 w/m2 at Key West. California wind <span class="hlt">energy</span> <span class="hlt">potential</span> is even greater than that of Florida with Fairfield exhibiting mean annual wind speeds of 5.9 m/s and average wind power density ratings of 327 w/m2 followed by the Mojave and Palmdale areas with mean annual wind speeds of 5.0 m/s and 4.6 m/s, respectively. Wind power density ratings for Mojave are 240 w/m2 and 153 w/m2 at Palmdale. These results help confirm that wind <span class="hlt">energy</span> continues to offer a clean, cost-effective, inexhaustible, and readily available means of helping to curb global warming while answering the increasing demand for electricity.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://adsabs.harvard.edu/abs/2014EGUGA..16.8957R','NASAADS'); return false;" href="http://adsabs.harvard.edu/abs/2014EGUGA..16.8957R"><span id="translatedtitle">Onshore wind <span class="hlt">energy</span> <span class="hlt">potential</span> over Iberia: present and future projections</span></a></p> <p><a target="_blank" href="http://adsabs.harvard.edu/abstract_service.html">NASA Astrophysics Data System (ADS)</a></p> <p>Rochinha, Carlos A.; Santos, João A.; Liberato, Margarida L.

Further, increasing attention has been devoted to renewable <span class="hlt">energy</span> sources in a climate change context. While advantages of wind <span class="hlt">energy</span> are widely recognized, its distribution is not spatially homogeneous and not uniform throughout the year. Hence, understanding these spatial-temporal distributions is critical in power system planning. The present study aims at assessing the <span class="hlt">potential</span> power output estimated from 10 m wind components simulated by a regional climate model (CCLM), driven by ERA40 reanalysis. Datasets are available on a grid with a high spatial resolution (approximately 20 km) and over a 40-yr period (1961-2000). Furthermore, several target sites, located in areas with high installed wind generation capacity, are selected for local-to-regional scale assessments. The results show that <span class="hlt">potential</span> wind power is higher over northern Iberia, mostly in Cantabria and Galicia, while Andalucía and Cataluña record the lowest values. With respect to the intra-annual variability, summer is by far the season with the lowest <span class="hlt">potential</span> <span class="hlt">energy</span> outputs. Furthermore, the inter-annual variability reveals an overall downward long-term trend over the 40-yr period, particularly in the winter time series. A CCLM transient experiment, forced by the SRES A1B emission scenario, is also discussed for a future period (2041-2070), after a model validation/calibration process (bias corrections). Significant changes in the wind power <span class="hlt">potential</span> are projected for the future throughout Iberia, but their magnitude largely depends on the locations.

The zeroth degree term in the spherical harmonic expansion agrees with the usual expression for the <span class="hlt">energy</span> of a radial density distribution. The second degree terms give a maximum nonhydrostatic <span class="hlt">energy</span> in the crust and mantle of -2.77 x 10 to the 29th ergs, an order of magnitude below McKenzie's (1966) estimate. McKenzie's result stems from mathematical error. Our figure is almost identical with Kaula's (1963) estimate of the minimum shear strain <span class="hlt">energy</span> in the mantle, a not unexpected result on the basis of the virial theorem. If the earth is assumed to be a homogeneous viscous oblate spheroid relaxing to an equilibrium shape, then a lower limit to the mantle viscosity of 1.3 x 10 to the 20th P is found by assuming that the total geothermal flux is due to viscous dissipation of <span class="hlt">energy</span>. This number is almost six orders of magnitude below MacDonald's (1966) estimate of the viscosity and removes his objection to convection. If the nonequilibrium figure is dynamically maintained by the earth acting as a heat engine at 1% efficiency, then the viscosity is 10 to the 22nd P, a number preferred by Cathles (1975) and Peltier and Andrew (1976) as the viscosity of the mantle.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://ntrs.nasa.gov/search.jsp?R=20020050253&hterms=new+energy&qs=Ntx%3Dmode%2Bmatchall%26Ntk%3DAll%26N%3D0%26No%3D40%26Ntt%3Dnew%2Benergy','NASA-TRS'); return false;" href="http://ntrs.nasa.gov/search.jsp?R=20020050253&hterms=new+energy&qs=Ntx%3Dmode%2Bmatchall%26Ntk%3DAll%26N%3D0%26No%3D40%26Ntt%3Dnew%2Benergy"><span id="translatedtitle">Rotational <span class="hlt">Energy</span> Transfer of N2 Gas Determined Using a New Ab Initio <span class="hlt">Potential</span> <span class="hlt">Energy</span> Surface</span></a></p> <p><a target="_blank" href="http://ntrs.nasa.gov/search.jsp">NASA Technical Reports Server (NTRS)</a></p> <p>Huo, Winifred M.; Stallcop, James R.; Partridge, Harry; Langhoff, Stephen R.

These <span class="hlt">potential</span> <span class="hlt">energy</span> surfaces require an accurate and balanced treatment of reactants, intermediates, and products. This difficult challenge is met with general multiconfiguration self-consistent-field (MCSCF) and multireference single- and double-excitation configuration interaction (MRSDCI) methods. In contrast to the more common single-reference electronic structure methods, this approach is capable of describing accurately molecular systems that are highly distorted away from their equilibrium geometries, including reactant, fragment, and transition-state geometries, and of describing regions of the <span class="hlt">potential</span> surface that are associated with electronic wave functions of widely varying nature. The MCSCF reference wave functions are designed to be sufficiently flexible to describe qualitatively the changes in the electronic structure over the broad range of geometries of interest. The necessary mixing of ionic, covalent, and Rydberg contributions, along with the appropriate treatment of the different electron-spin components (e.g. closed shell, high-spin open-shell, low-spin open shell, radical, diradical, etc.) of the wave functions, are treated correctly at this level. Further treatment of electron correlation effects is included using large scale multireference CI wave functions, particularly including the single and double excitations relative to the MCSCF reference space.

Examples include weatherization of low-income housing, efficiency programs, and renewable <span class="hlt">energy</span> development. Varying amounts have been collected and allocated depending on state needs and abilities. One question that arises is what are the <span class="hlt">potential</span> results of funding the different types of programs. What is the <span class="hlt">potential</span> for <span class="hlt">energy</span> efficiency or for renewable power, and what would be accomplished given the amount of funding that the system benefit charge may provide? The purpose of this project is to provide an initial estimate of the <span class="hlt">potential</span> for <span class="hlt">energy</span> efficiency and renewable <span class="hlt">energy</span> in North Carolina. This <span class="hlt">potential</span> could be funded by a public benefits fund resulting from a green power program being considered in the state. It concentrates on electric <span class="hlt">energy</span> savings and production. Savings in buildings can include improvements to space conditioning as well as improvements to lighting or other appliances. Distributed power <span class="hlt">potential</span>, through use of combined heat and power and renewables such as photovoltaic, wind, and biomass were examined. The goal is to provide information to decision makers who are developing a green power program in North Carolina. It will not be a complete and detailed study of all efficiency <span class="hlt">potentials</span> but is more of a scoping exercise to determine the relative impacts and begin the process for a more definitive study at a later date. Statewide <span class="hlt">energy</span> savings <span class="hlt">potential</span> cannot be directly measured but must be calculated. First, the word ''<span class="hlt">potential</span>'' means that the savings have not occurred yet. Second, the savings are often only indirectly measured by estimating what <span class="hlt">energy</span> use there would have been without the changes in technology or behavior. Calculations through sampling and statistical analysis or by simulation are a necessary part of any mechanism to determine <span class="hlt">energy</span> savings <span class="hlt">potential</span>. There are currently several methods for calculating savings. Extrapolation of savings achieved from specific programs, surveys of existing building stock or <span class="hlt">energy</span>-using activities, computer calculations of representative building types, and economic simulations all provide insight into the amount of <span class="hlt">energy</span> that could be saved.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://adsabs.harvard.edu/abs/2013AGUFMGP23A0998F','NASAADS'); return false;" href="http://adsabs.harvard.edu/abs/2013AGUFMGP23A0998F"><span id="translatedtitle">IRETHERM: Magnetotelluric studies of Irish radiothermal granites and their geothermal <span class="hlt">energy</span> <span class="hlt">potential</span></span></a></p> <p><a target="_blank" href="http://adsabs.harvard.edu/abstract_service.html">NASA Astrophysics Data System (ADS)</a></p> <p>Farrell, T. F.; Jones, A. G.; Muller, M.

One aspect of IRETHERM's research focuses on Ireland's radiothermal granites, where increased concentrations of radioelements provide elevated heat-production (HP), heat-flow (HF) and subsurface temperatures. An understanding of the contribution of granites to the thermal field of Ireland is of key importance in assessing the geothermal <span class="hlt">energy</span> <span class="hlt">potential</span> of this low-enthalpy setting. This study focuses on the Leinster granite, the Galway granite and the buried Kentstown granite. Shallow (<250 m) boreholes were drilled into the exposed Caledonian Leinster and Galway granites as part of an early 1980's EU-funded geothermal project. These studies yielded HP = 2-3 ?Wm-3 and HF = 80 mWm-2 at the Sally Gap borehole in the Northern Units of the Leinster granite. In the Galway granite batholith, the Costelloe-Murvey granite returned HP = 7 ?Wm-3 and HF = 77 mWm-2, measured at the Ros a Mhil borehole. The lower heat-flow encountered at the Ros a Mhil borehole suggests that the associated high heat production does not extend to great depth. The buried Kentstown granite has associated with it a significant negative Bouguer <span class="hlt">anomaly</span> and was intersected by two mineral exploration boreholes at depths of 660 m and 485 m. Heat production has been measured at 2.4 ?Wm-3 in core samples taken from the weathered top 30m of the granite. The core of this study consists of an ambitious program of magnetotelluric (MT) and audio-magnetotelluric (AMT) data acquisition across the three granite bodies, extending over three fieldwork seasons. MT and AMT data were collected at 59 locations along two profiles over the Leinster granite. Preliminary results show that the northern units of the Leinster granite extend to depths of 2-5 km. Over the Galway granite, MT and AMT data have been collected at a total of 29 sites, with a further 46 sites to be collected in August 2013 (of these 75 sites, 33 will consist of AMT-only data acquisition, with both MT and AMT recorded at the remaining 42). Preliminary results derived from the 29 sites recorded in 2012 show a deep resistor extending to depths of 15-20 km beneath the central block of the batholith, with the resistive body extending to depths of 3.5-7.0 km west of the Shannawona fault. MT and AMT data acquired along a profile at 22 locations over the Kentstown granite suggests that the top of this buried granite is at a depth of 380m beneath the center of the gravity <span class="hlt">anomaly</span>. The MT and AMT data will be integrated with gravity data and seismic refraction data (in the case of the Leinster granite) to identify deeply penetrating faults, which may provide pathways for hydrothermal fluids, and to produce a robust estimation of the volumetric extent of the granites. Geochemical data will also be incorporated to ultimately constrain the local and regional thermal contribution and geothermal <span class="hlt">energy</span> <span class="hlt">potential</span> of the granites.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://www.ncbi.nlm.nih.gov/pubmed/26476072','PUBMED'); return false;" href="http://www.ncbi.nlm.nih.gov/pubmed/26476072"><span id="translatedtitle">Terahertz absorption spectra and <span class="hlt">potential</span> <span class="hlt">energy</span> distribution of liquid crystals.</span></a></p> <p><a target="_blank" href="http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?DB=pubmed">PubMed</a></p> <p>Chen, Zezhang; Jiang, Yurong; Jiang, Lulu; Ma, Heng</p> <p>2016-01-15</p> <p>In this work, the terahertz (THz) absorption spectra of a set of nematic liquid crystals were studied using the density functional theories (DFT).

The approaches used can be classified into three categories: frequency tuning, multi-modal <span class="hlt">energy</span> harvesting, and nonlinear <span class="hlt">energy</span> harvesting1. Of the nonlinear harvesting approaches studied, bistable <span class="hlt">energy</span> harvesters have been shown to have the most robust performance when subjected to broadband harmonic & stochastic excitation2-4. A conventional method for developing a nonlinear bistable restoring force is through use of magnetic repulsion.

However, clear evidence is recorded in coastal sediments worldwide that past changes in environmental conditions have caused hydrates to become unstable and trigger both massive submarine landslides and the development of crater-like pockmarks, thereby releasing methane into the overlying seawater and atmosphere, where it acts as a powerful greenhouse gas. Arctic permafrost is thawing, and environmental changes can alter ocean circulation to warm the seafloor, causing hydrates to dissociate or dissolve in the sediments beneath. Decades of focused research provide a firm understanding of laboratory conditions under which hydrates become unstable and dissociate, and how hydrate reserves form when microbes convert organic material into methane, which can also dissolve and be carried by pore waters into the hydrate stability zone. Despite these advances, many key questions that concern both the resource <span class="hlt">potential</span> of hydrates and their role in causing environmental geohazards, are intimately tied to the more poorly understood behavior of hydrate <span class="hlt">anomalies</span>, which tend to be concentrated in the large pores of sand layers and form segregated lenses and nodules in muds. We present simple models designed to unravel the importance of the diverse physical interactions (i.e. flow focusing, free-gas infiltration, and pore-scale solubility effects) that help control how hydrate <span class="hlt">anomalies</span> form. Predicted hydrate distributions are qualitatively different when accumulation in <span class="hlt">anomalies</span> is supplied primarily by: 1. aqueous flow through sediments with enhanced permeability, 2. free-gas transport high above the three-phase stability boundary, or 3. diffusive transport along solubility gradients associated with pore-scale effects.

We show that the observed velocities match this expression with an RMS misfit of 0.5 mm/yr. This agreement suggests that deformation of the Apennines reflects a balance, within the mountain chain itself, between lateral variations in GPE and the stresses required to deform the lithosphere. Forces arising from processes external to the belt are not required to explain the observations.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://adsabs.harvard.edu/abs/2015JPCM...27C3201R','NASAADS'); return false;" href="http://adsabs.harvard.edu/abs/2015JPCM...27C3201R"><span id="translatedtitle">Computer simulations of glasses: the <span class="hlt">potential</span> <span class="hlt">energy</span> landscape</span></a></p> <p><a target="_blank" href="http://adsabs.harvard.edu/abstract_service.html">NASA Astrophysics Data System (ADS)</a></p> <p>Raza, Zamaan; Alling, Björn; Abrikosov, Igor A.</p> <p>2015-07-01</p> <p>We review the current state of research on glasses, discussing the theoretical background and computational models employed to describe them.

This article provides a broad overview of the rich phenomenology of glasses, followed by a summary of the theoretical frameworks developed to describe this phenomonology. We discuss the background of the PEL in detail, the onerous task of how to generate computer models of glasses, various methods of analysing numerical simulations, and the literature on the most commonly used model systems. Finally, we tackle the problem of how to distinguish a good glass former from a good crystal former from an analysis of the PEL.

First, the average particle velocity is found as a function of the driving velocity and the wavelength of the optical <span class="hlt">potential</span> <span class="hlt">energy</span> landscape. The relationship between average particle velocity and driving velocity is found to be well described by a theoretical model treating the landscape as sinusoidal, but only at small trap spacings. At larger trap spacings, a nonsinusoidal model for the landscape must be used. Subsequently, the critical velocity required for a particle to move across the landscape is determined as a function of the wavelength of the landscape. Finally, the velocity of a particle driven at a velocity far exceeding the critical driving velocity is examined. Both of these results are again well described by the two theoretical routes for small and large trap spacings, respectively. Brownian motion is found to have a significant effect on the critical driving velocity but a negligible effect when the driving velocity is high.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://ntrs.nasa.gov/search.jsp?R=20020035539&hterms=Potential+energy&qs=Ntx%3Dmode%2Bmatchall%26Ntk%3DAll%26N%3D0%26No%3D10%26Ntt%3DPotential%2Benergy','NASA-TRS'); return false;" href="http://ntrs.nasa.gov/search.jsp?R=20020035539&hterms=Potential+energy&qs=Ntx%3Dmode%2Bmatchall%26Ntk%3DAll%26N%3D0%26No%3D10%26Ntt%3DPotential%2Benergy"><span id="translatedtitle">An Ab Initio Based <span class="hlt">Potential</span> <span class="hlt">Energy</span> Surface for Water</span></a></p> <p><a target="_blank" href="http://ntrs.nasa.gov/search.jsp">NASA Technical Reports Server (NTRS)</a></p> <p>Partridge, Harry; Schwenke, David W.; Langhoff, Stephen R.

The identification of reaction pathways using modern quantum mechanics calculations, however, often requires a high demand in computational power and good chemical intuition on the reaction. Here, a new reaction path searching method is developed by combining our recently developed transition state (TS) location method, namely, the constrained Broyden dimer method, with a basin-filling method via bias <span class="hlt">potentials</span>, which allows the system to walk out from the <span class="hlt">energy</span> traps at a given reaction direction. In the new method, the reaction path searching starts from an initial state without the need for preguessing the TS-like or final state structure and can proceed iteratively to the final state by locating all related TSs and intermediates. In each elementary reaction step, a reaction direction, such as a bond breaking, needs to be specified, the information of which is refined and preserved as a normal mode through biased dimer rotation. The method is tested successfully on the Baker reaction system (50 elementary reactions) with good efficiency and stability and is also applied to the <span class="hlt">potential</span> <span class="hlt">energy</span> surface exploration of multistep reaction processes in the gas phase and on the surface. The new method can be applied for the computational screening of new catalytic materials with a minimum requirement of chemical intuition.

The policy describes five types of effluent trades: point source/point source, point source/nonpoint source, pretreatment, intraplant and nonpoint source/nonpoint source. This paper evaluates the feasibility of implementing these types of effluent trading for facilities in the oil and gas, electric power and coal industries. This paper finds that the <span class="hlt">potential</span> for effluent trading in these industries is limited because trades would generally need to involve toxic pollutants, which can only be traded under a narrow range of circumstances.

The sustained ventri-cular tachycardia exhibited electrophysiologic criteria of a "re-entrant" mechanism.

We give a simple criterion for when DC-DFT should be more accurate than self-consistent DFT that can be applied for most cases.

For a satellite in hydrostatic equilibrium, its gravitational field can be modeled adequately by a truncated spherical harmonic series of degree two. However, a fourth degree field is required in order to fit the second Galileo flyby (G2).

In fact, a plot of the Doppler residuals , after removal of the best-fit model for the zero degree term (GM) and the second degree moments (J2 and C22), suggests that if an <span class="hlt">anomaly</span> exists, it is located downtrack of the closest approach point, closer to the equator.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://www.osti.gov/scitech/servlets/purl/1123477','SCIGOV-STC'); return false;" href="http://www.osti.gov/scitech/servlets/purl/1123477"><span id="translatedtitle"><span class="hlt">Energy</span> Saving Melting and Revert Reduction Technology (<span class="hlt">Energy</span>-SMARRT): Surface/Near Surface Indication - Characterization of Surface <span class="hlt">Anomalies</span> from Magnetic Particle and Liquid Penetrant Indications</span></a></p> <p><a target="_blank" href="http://www.osti.gov/scitech">SciTech Connect</a></p> <p>Griffin, John</p> <p>2014-02-20</p> <p>The systematic study and characterization of surface indications has never been conducted. Producers and users of castings do not have any data on which they can reliably communicate the nature of these indications or their effect on the performance of parts. Clearly, the ultimate intent of any work in this area is to eliminate indications that do in fact degrade properties. However, it may be impractical physically and/or financially to eliminate all surface imperfections. This project focused on the ones that actually degrade properties. The initial work was to identify those that degrade properties. Accurate numerical simulations of casting service performance allow designers to use the geometric flexibility of castings and the superior properties of steel to produce lighter weight and more <span class="hlt">energy</span> efficient components for transportation systems (cars and trucks), construction, and mining. Accurate simulations increase the net melting <span class="hlt">energy</span> efficiency by improving casting yield and reducing rework and scrap.

A small adjustment is made to the PES to improve the agreement of line positions from theory and experiment. The theoretical line positions are obtained from variational ro-vibrational calculations using the exact kinetic <span class="hlt">energy</span> operator. For the lines being fitted, the root-mean-square error was reduced from 6.9 to 0.08 /cm. We were then able to match 30,092 of the 30,117 lines from the HITRAN 96 data base to theoretical lines, and 80% of the line positions differed less than 0.1 /cm. About 3% of the line positions in the experimental data base appear to be incorrect. Theory predicts the existence of many additional weak lines with intensities above the cutoff used in the data base. To obtain results of similar accuracy for HDO, a mass dependent correction to the PH is introduced and is parameterized by simultaneously fitting line positions for HDO and D2O. The mass dependent PH has good predictive value for T2O and HTO. Nonadiabatic effects are not explicitly included. Line strengths for vibrational bands summed over rotational levels usually agree well between theory and experiment, but individual line strengths can differ greatly.

Most of them occur sporadically, i.e. there is no familial history of lesions, yet in a few cases clear inheritance is observed. These inherited forms are often characterized by multifocal lesions that are mainly small in size and increase in number with patient’s age. On the basis of these inherited forms, molecular genetic studies have unraveled a number of inherited mutations giving direct insight into the pathophysiological cause and the molecular pathways that are implicated. Genetic defects have been identified for hereditary haemorrhagic telangiectasia (HHT), inherited cutaneomucosal venous malformation (VMCM), glomuvenous malformation (GVM), capillary malformation - arteriovenous malformation (CM-AVM), cerebral cavernous malformation (CCM) and some isolated and syndromic forms of primary lymphedema. We focus on these disorders, the implicated mutated genes and the underlying pathogenic mechanisms. We also call attention to the concept of Knudson’s double-hit mechanism to explain incomplete penetrance and the large clinical variation in expressivity of inherited vascular <span class="hlt">anomalies</span>. This variability renders the making of correct diagnosis of the rare inherited forms difficult. Yet, the identification of the pathophysiological causes and pathways involved in them has had an unprecedented impact on our thinking of their etiopathogenesis, and has opened the doors towards a more refined classification of vascular <span class="hlt">anomalies</span>. It has also made it possible to develop animal models that can be tested for specific molecular therapies, aimed at alleviating the dysfunctions caused by the aberrant genes and proteins.

They occur naturally in offshore and terrestrial environments, in the areas where temperature is at least seasonally low (i.e. close to or below freezing), bathymetric, geostatic, ice, or permafrost pressure is sufficiently high, and the source of hydrocarbons is available. These factors (regional and local geological conditions of 21 locations grouped into 13 study regions worldwide offshore and one in permafrost environments with proven, reported, and inferred presence of gas hydrates) have been recently researched by Geoexplorers International, Inc. Conservative estimations from Geoexplorers International suggest that the world's total gas hydrates may contain 7,000 to 50,000 tcf of natural gas. Although at this time exploitation of gas trapped in the hydrate zone and below is not economically viable, because estimated reserves are enormous, they should be seriously considered as <span class="hlt">potential</span> <span class="hlt">energy</span> resource. Smaller, but less dispersed massive gas hydrate deposits associated with fault zones may be the first offshore gas resource to become economic. This research, particularly of the Messoyakh gas field, has proved that the presence of gas hydrates provides very useful information in exploration for conventional oil and gas deposits. Gas hydrates indicate ongoing hydrocarbon generation in the sediments. Hydrates are valuable to assess the present heat flow and thermal history of a region. Since gas hydrates exist only under a very limited range of pressure and temperature, deviation in patterns of their occurrence can be related to changes in pore water chemistry, hydrocarbon composition, or pressure and temperature gradient <span class="hlt">anomalies</span>.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://www.ncbi.nlm.nih.gov/pubmed/21689919','PUBMED'); return false;" href="http://www.ncbi.nlm.nih.gov/pubmed/21689919"><span id="translatedtitle">Material and <span class="hlt">energy</span> recovery in integrated waste management systems: the <span class="hlt">potential</span> for <span class="hlt">energy</span> recovery.</span></a></p> <p><a target="_blank" href="http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?DB=pubmed">PubMed</a></p> <p>Consonni, Stefano; Viganò, Federico</p> <p>2011-01-01</p> <p>This article is part of a set of six coordinated papers reporting the main findings of a research project carried out by five Italian universities on "Material and <span class="hlt">energy</span> recovery in Integrated Waste Management Systems (IWMS)".

By micro-<span class="hlt">anomalies</span>, we primarily refer to micro-cracks of size 10-100 μm (depending on the material), while macro-level response variables imply, e.g., strains, strain <span class="hlt">energy</span> density of macro-level structures (typical size often varying in the order of 10-100 m). The micro-<span class="hlt">anomalies</span> referred above are not discernible to the naked eyes. Nevertheless, they can cause catastrophic failures of structural systems due to fatigue cyclic loading that results in initiation of fatigue cracks. Analysis of such precursory state of internal damage evolution, before amacro-crack visibly appears (say, size of a few cms), is beyond the scope of the conventional crack propagation analysis, e.g., classical fracture mechanics. The present work addresses this issue in a certain sense by incorporating the effects of micro-cracks into the macro-scale constitutive material properties (e.g., constitutive elasticity tensors) within a probabilistic formalism based on random matrix theory, maximum entropy principle, and principles of minimum complementary <span class="hlt">energy</span> and minimum <span class="hlt">potential</span> <span class="hlt">energy</span>. Distinct differences are observed in the macro-level response characteristics depending on the presence or absence of micro-cracks. This particular feature can now be used to reliably detect micro-cracks from experimental measurements of macro-observables. The present work, therefore, further proposes an efficient and robust optimization scheme: (1) to identify locations of micro-cracks in macroscopic structural systems, say, in an aircraft wing which is of the size of 10- 100 m, and (2) to determine the weakened (due to the presence of micro-cracks) macroscopic material properties which will be useful in predicting the remaining useful life of structural systems. The proposed optimization scheme achieves better convergence rate and accuracy by exploiting positive-definite structure of the macroscopic constitutive matrices.</p> </li> </ol> <div class="pull-right"> <ul class="pagination"> <li><a href="#" onclick='return showDiv("page_1");'>«</a></li> <li><a href="#" onclick='return showDiv("page_15");'>15</a></li> <li><a href="#" onclick='return showDiv("page_16");'>16</a></li> <li class="active"><span>17</span></li> <li><a href="#" onclick='return showDiv("page_18");'>18</a></li> <li><a href="#" onclick='return showDiv("page_19");'>19</a></li> <li><a href="#" onclick='return showDiv("page_25");'>»</a></li> </ul> </div> </div><!-- col-sm-12 --> </div><!-- row --> </div><!-- page_17 --> <div id="page_18" class="hiddenDiv"> <div class="row"> <div class="col-sm-12"> <div class="pull-right"> <ul class="pagination"> <li><a href="#" onclick='return showDiv("page_1");'>«</a></li> <li><a href="#" onclick='return showDiv("page_16");'>16</a></li> <li><a href="#" onclick='return showDiv("page_17");'>17</a></li> <li class="active"><span>18</span></li> <li><a href="#" onclick='return showDiv("page_19");'>19</a></li> <li><a href="#" onclick='return showDiv("page_20");'>20</a></li> <li><a href="#" onclick='return showDiv("page_25");'>»</a></li> </ul> </div> </div> </div> <div class="row"> <div class="col-sm-12"> <ol class="result-class" start="341"> <li> <p><a target="_blank" onclick="trackOutboundLink('http://www.ncbi.nlm.nih.gov/pubmed/25719956','PUBMED'); return false;" href="http://www.ncbi.nlm.nih.gov/pubmed/25719956"><span id="translatedtitle">Networks of triboelectric nanogenerators for harvesting water wave <span class="hlt">energy</span>: a <span class="hlt">potential</span> approach toward blue <span class="hlt">energy</span>.</span></a></p> <p><a target="_blank" href="http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?DB=pubmed">PubMed</a></p> <p>Chen, Jun; Yang, Jin; Li, Zhaoling; Fan, Xing; Zi, Yunlong; Jing, Qingshen; Guo, Hengyu; Wen, Zhen; Pradel, Ken C; Niu, Simiao; Wang, Zhong Lin</p> <p>2015-03-24</p> <p>With 70% of the earth's surface covered with water, wave <span class="hlt">energy</span> is abundant and has the <span class="hlt">potential</span> to be one of the most environmentally benign forms of electric <span class="hlt">energy</span>.

On the basis of the measured output of a single TENG, the TENG-NW is expected to give an average power output of 1.15 MW from 1 km(2) surface area.

The underlying hypothesis is that DNA replicates with reduced fidelity when its normal right-handed B-structure is altered, and one result is a higher mutation rate. This change in structure may occur normally at a low incidence, for example by the formation of hairpin loops in appropriate sequences, but it may be enhanced greatly after covalent modification by a mutagenic substance.

The PES is dominated by a single conformation, as other stable minima are shown to kinetically relax in the expansion to the global minimum. Consistently, the rotational spectrum reveals a single conformation. Fluoroxene adopts a CS heavy-atom planar skeleton structure in the gas phase, with a cis-trans conformation (cis for the CH2[double bond, length as m-dash]CH-O-CH2- and trans for the [double bond, length as m-dash]CH-O-CH2-CF3 part). The sensitivity of a recently-built CP-FTMW spectrometer at the UPV/EHU is demonstrated by the detection of five isotopologues of fluoroxene in natural abundance, corresponding to the (13)C and (18)O monosubstituted species. The rS and r0 structures were determined and are in good agreement with theoretical predictions using the MP2, B3LYP and M06-2X methods.

The present results are in qualitative accord with the BAC-MP4 calculations, but there are differences as large as 8 kcal/mol in the detailed energetics. Addition of NH to NO on a (2)A' surface, which correlated with N2 + OH or H + N2O products, involves barriers of 3.2 kcal/mol (trans) and 6.3 kcal/mol (cis). Experimental evidence for these barriers is found in earlier works. The (2)A' surface has no barrier to addition, but does not correlate with products. Surface crossings between the barrierless (2)A' surface and the (2)A' surface may be important. Production of N2 + OH products is predicted to occur via a planar saddle point of (2)A' symmetry. This is in accord with the preferential formation of II(A') lambda doublet levels of OH in earlier experiments. Addition of NH (1)delta to NO is found to occur on an excited state surface and is predicted to lead to N2O product as observed in earlier works.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://files.eric.ed.gov/fulltext/EJ888131.pdf','ERIC'); return false;" href="http://files.eric.ed.gov/fulltext/EJ888131.pdf"><span id="translatedtitle"><span class="hlt">Potential</span> Ambient <span class="hlt">Energy</span>-Harvesting Sources and Techniques</span></a></p> <p><a target="_blank" href="http://www.eric.ed.gov/ERICWebPortal/search/extended.jsp?_pageLabel=advanced">ERIC Educational Resources Information Center</a></p> <p>Yildiz, Faruk</p> <p>2009-01-01</p> <p>Ambient <span class="hlt">energy</span> harvesting is also known as <span class="hlt">energy</span> scavenging or power harvesting, and it is the process where <span class="hlt">energy</span> is obtained from the environment.

The properties of lignite fly ash, such as fine particle size, porosity, hydrophobic character, combined with the properties, such as high porosity and low specific gravity, of an agricultural by-product, namely sawdust, resulted in an effective oil-sorbent material. The materials were mixed either in the dry state or in aqueous solution. The oil sorption behaviour of the fly ash-sawdust mixtures was investigated in both marine and dry environments. Mixtures containing fly ash and 15-25% w/w sawdust performed better than each material alone when added to oil spills in a marine environment, as they formed a cohesive semi-solid phase, adsorbing almost no water, floating on the water surface and allowing total oil removal. For the clean-up of an oil spill 0.5 mm thick with surface area 1000 m(2), 225-255 kg of lignite fly ash can be utilized with the addition of 15-25% w/w sawdust. Fly ash-sawdust mixtures have also proved efficient for oil spill clean-up on land, since their oil sorption capacity in dry conditions was at least 0.6-1.4 g oil g(-1) mixture. The higher calorific value of the resultant oil-fly ash-sawdust mixtures increased up to that of bituminous coal and oil and exceeded that of lignite, thereby encouraging their utilization as alternative fuels especially in the cement industry, suggesting that the remaining ash can contribute in clinker production.

If heat flow is considered as a surface expression of geothermal processes at depth, the analysis of the data set should reveal properties of those thermal processes. They do, but on a variety of scales. For this review heat flow maps are classified by 4 different horizontal scales of 10 n km (n = 1, 2, 3 and 4) and attention is focussed on the interpretation of <span class="hlt">anomalies</span> which appear with characteristic dimensions of 10 (n - 1) km in the respective representations. The largest scale of 10 4 km encompasses heat flow on a global scale. Global heat loss is 4 10 13 W and the process of sea floor spreading is the principal agent in delivering much of this heat to the surface. Correspondingly, active ocean ridge systems produce the most prominent heat flow <span class="hlt">anomalies</span> at this scale with characteristic widths of 10 3 km. Shields, with similar dimensions, exhibit negative <span class="hlt">anomalies</span>. The scale of 10 3 km includes continent wide displays. Heat flow patterns at this scale mimic tectonic units which have dimensions of a few times 10 2 km, although the thermal boundaries between these units are sometimes sharp. Heat flow <span class="hlt">anomalies</span> at this scale also result from plate tectonic processes, and are associated with arc volcanism, back arc basins, hot spot traces, and continental rifting. There are major controversies about the extent to which these surface thermal provinces reflect upper mantle thermal conditions, and also about the origin and evolution of the thermal state of continental lithosphere. Beginning with map dimensions of 10 2 km thermal <span class="hlt">anomalies</span> of scale 10 1 km, which have a definite crustal origin, become apparent. The origin may be tectonic, geologic, or hydrologic. Ten kilometers is a common wavelength of topographic relief which drives many groundwater flow systems producing thermal <span class="hlt">anomalies</span>. The largest recognized continental geothermal systems have thermal <span class="hlt">anomalies</span> 10 1 km wide and are capable of producing hundreds of megawatts of thermal <span class="hlt">energy</span>. The smallest scale addressed in this paper is 10 1 km. Worldwide interest in exploiting geothermal systems has been responsible for a recent accumulation of heat flow data on the smallest of scales considered here. The exploration nature of the surveys involve 10's of drillholes and reveal thermal <span class="hlt">anomalies</span> having widths of 10 0 km. These are almost certainly connected to surface and subsurface fluid discharge systems which, in spite of their restricted size, are typically delivering 10 MW of heat to the near surface environment.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://www.osti.gov/scitech/biblio/20990988','SCIGOV-STC'); return false;" href="http://www.osti.gov/scitech/biblio/20990988"><span id="translatedtitle">Breakup threshold <span class="hlt">anomaly</span> in the elastic scattering of {sup 6}Li on {sup 27}Al</span></a></p> <p><a target="_blank" href="http://www.osti.gov/scitech">SciTech Connect</a></p> <p>Figueira, J.

A severalfold increase in global electricity demand by the middle of the 21st century seems inevitable, with the largest increment from large-population developing countries such as China and India.

This procedure requires constraints on the chiral matter representations of the gauge group that are consistent with known results from orbifold compactifications. Pauli-Villars (PV) regulator fields allow for the cancellation of all quadratic and logarithmic divergences, as well as most linear divergences. If all linear divergences were canceled, the theory would be <span class="hlt">anomaly</span> free, with noninvariance of the action arising only from Pauli-Villars masses.

These include uses such as identifying possible heart conditions from an Electrocardiography (ECG) signals or predicting earthquakes via seismographic data. Over the many choices of <span class="hlt">anomaly</span> detection algorithms, it is important to compare possible methods. In this paper, we examine and compare two approaches to <span class="hlt">anomaly</span> detection and see how data fusion methods may improve performance. The first approach involves using an artificial neural network (ANN) to detect <span class="hlt">anomalies</span> in a wavelet de-noised signal. The other method uses a perspective neural network (PNN) to analyze an arbitrary number of "perspectives" or transformations of the observed signal for <span class="hlt">anomalies</span>. Possible perspectives may include wavelet de-noising, Fourier transform, peak-filtering, etc.. In order to evaluate these techniques via signal fusion metrics, we must apply signal preprocessing techniques such as de-noising methods to the original signal and then use a neural network to find <span class="hlt">anomalies</span> in the generated signal. From this secondary result it is possible to use data fusion techniques that can be evaluated via existing data fusion metrics for single and multiple perspectives. The result will show which <span class="hlt">anomaly</span> detection method, according to the metrics, is better suited overall for <span class="hlt">anomaly</span> detection applications.

Recently, we showed that one-loop <span class="hlt">anomaly</span>-mediated gaugino masses should be associated with unbroken supersymmetry (SUSY). This counterintuitive result arises because the underlying symmetry structure of (broken) SUGRA in flat space is in fact (unbroken) SUSY in anti-de Sitter (AdS) space. When quantum corrections are regulated in a way that preserves SUGRA, the underlying AdS curvature (proportional to the gravitino mass) necessarily appears in the regulated action, yielding soft masses without corresponding goldstino couplings. In this paper, we extend our analysis of <span class="hlt">anomaly</span> mediation to sfermion soft masses. Already at tree-level we encounter a number of surprises, including the fact that zero soft masses correspond to broken (AdS) SUSY. At one-loop, we explain how <span class="hlt">anomaly</span> mediation appears when regulating SUGRA in a way that preserves super-Weyl invariance. We find that recent claims in the literature about the non-existence of <span class="hlt">anomaly</span> mediation were based on a Wilsonian effective action with residual gauge dependence, and the gauge-invariant 1PI effective action contains the expected <span class="hlt">anomaly</span>-mediated spectrum. Finally, we calculate the sfermion spectrum to all orders, and use supertrace relations to derive the familiar two-loop soft masses from minimal <span class="hlt">anomaly</span> mediation, as well as unfamiliar tree-level and one-loop goldstino couplings consistent with renormalization group invariance.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://hdl.handle.net/2060/20040034236','NASA-TRS'); return false;" href="http://hdl.handle.net/2060/20040034236"><span id="translatedtitle">Reliability of CHAMP <span class="hlt">Anomaly</span> Continuations</span></a></p> <p><a target="_blank" href="http://ntrs.nasa.gov/search.jsp">NASA Technical Reports Server (NTRS)</a></p> <p>vonFrese, Ralph R.

However, <span class="hlt">anomaly</span> continuation is severely limited by the non-uniqueness of the process and satellite <span class="hlt">anomaly</span> errors. Indeed, our numerical <span class="hlt">anomaly</span> simulations from satellite to airborne altitudes show that effective downward continuations of the CHAMP data are restricted to within approximately 50 km of the observation altitudes while upward continuations can be effective over a somewhat larger altitude range. The great unreliability of downward continuation requires that the satellite geopotential observations must be analyzed at satellite altitudes if the <span class="hlt">anomaly</span> details are to be exploited most fully. Given current <span class="hlt">anomaly</span> error levels, joint inversion of satellite and near- surface <span class="hlt">anomalies</span> is the best approach for implementing satellite geopotential observations for subsurface studies.

The system of equations describing the model is nonlinear and quasi -geostrophic (linear balance). Static stability is variable in the model. A moisture budget is calculated in the lower layer only. Convective adjustment is used to avoid supercritical temperature lapse rates. The mechanical forcing of topography is introduced as a vertical velocity at the lower boundary. Solar forcing is specified assuming a daily mean zenith angle. The differential diabatic heating between land and sea is parameterized. On land- and sea-ice surfaces, a steady state thermal <span class="hlt">energy</span> equation is solved to calculate the surface temperature. On the oceans, the sea surface temperature is specified as the climatological average for January, February and March circulations. Experiments are designed to study the response of the atmosphere to thermal <span class="hlt">anomalies</span> at the lower boundary or in the midtroposphere. The "memory" in the atmosphere of such <span class="hlt">anomalies</span>, after they have decayed, is also studied.

This report delineates the economic, social, and political costs of such a foreign oil dependency. These costs are often intangible, but combined they clearly constitute a greater price for imported petroleum than the strictly economic cost.

The second half of this report estimates that by the year 2000, solar <span class="hlt">energy</span> technologies can displace 3.6 quads of petroleum. This figure includes solar <span class="hlt">energy</span> applications in utilities, industrial and agricultural process heat, and transportation. The estimate can be treated as a lower bound; if the United States were to achieve the proposed goal of 20 quads by 2000, the amount of displaced oil probably would be greater.

Failure to address these challenges will inhibit the growth of the developing world and will negatively impact the standard of living and security of future generations in all nations. The solutions to these challenges will require multidisciplinary research across the social and physical sciences and engineering. Although perhaps not always recognized, geotechnical engineering expertise is critical to the solution of many <span class="hlt">energy</span> and sustainability-related problems. Hence, geotechnical engineers and academicians have opportunity and responsibility to contribute to the solution of these worldwide problems. Research will need to be extended to non-standard issues such as thermal properties of soils; sediment and rock response to extreme conditions and at very long time scales; coupled hydro-chemo-thermo-bio-mechanical processes; positive feedback systems; the development of discontinuities; biological modification of soil properties; spatial variability; and emergent phenomena. Clearly, the challenges facing geotechnical engineering in the future will require a much broader knowledge base than our traditional educational programs provide. The geotechnical engineering curricula, from undergraduate education through continuing professional education, must address the changing needs of a profession that will increasingly be engaged in alternative/renewable <span class="hlt">energy</span> production; <span class="hlt">energy</span> efficiency; sustainable design, enhanced and more efficient use of natural resources, waste management, and underground utilization.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://adsabs.harvard.edu/abs/2015ApPhL.107n3904C','NASAADS'); return false;" href="http://adsabs.harvard.edu/abs/2015ApPhL.107n3904C"><span id="translatedtitle">Nonlinear time-varying <span class="hlt">potential</span> bistable <span class="hlt">energy</span> harvesting from human motion</span></a></p> <p><a target="_blank" href="http://adsabs.harvard.edu/abstract_service.html">NASA Astrophysics Data System (ADS)</a></p> <p>Cao, Junyi; Wang, Wei; Zhou, Shengxi; Inman, Daniel J.; Lin, Jing</p> <p>2015-10-01</p> <p>A theoretical and experimental investigation into nonlinear bistable <span class="hlt">energy</span> harvesting with time-varying <span class="hlt">potential</span> <span class="hlt">energy</span> is presented.

These networks can be extremely large and so detecting any changes in their structure can be computationally challenging; hence, computationally fast, parallelisable methods for monitoring the network are paramount. For this reason the methods presented here use independent node and edge based models to detect locally anomalous substructures within communication networks. As a first stage, the aim is to detect changes in the data streams arising from node or edge communications. Throughout the thesis simple, conjugate Bayesian models for counting processes are used to model these data streams. A second stage of analysis can then be performed on a much reduced subset of the network comprising nodes and edges which have been identified as <span class="hlt">potentially</span> anomalous in the first stage. The first method assumes communications in a network arise from an inhomogeneous Poisson process with piecewise constant intensity. <span class="hlt">Anomaly</span> detection is then treated as a changepoint problem on the intensities. The changepoint model is extended to incorporate seasonal behavior inherent in communication networks. This seasonal behavior is also viewed as a changepoint problem acting on a piecewise constant Poisson process. In a static time frame, inference is made on this extended model via a Gibbs sampling strategy. In a sequential time frame, where the data arrive as a stream, a novel, fast Sequential Monte Carlo (SMC) algorithm is introduced to sample from the sequence of posterior distributions of the change points over time. A second method is considered for monitoring communications in a large scale computer network. The usage patterns in these types of networks are very bursty in nature and don’t fit a Poisson process model. For tractable inference, discrete time models are considered, where the data are aggregated into discrete time periods and probability models are fitted to the communication counts. In a sequential analysis, anomalous behavior is then identified from outlying behavior with respect to the fitted predictive probability models. Seasonality is again incorporated into the model and is treated as a changepoint model on the transition probabilities of a discrete time Markov process. Second stage analytics are then developed which combine anomalous edges to identify anomalous substructures in the network.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://adsabs.harvard.edu/abs/1990MPLA....5.1223B','NASAADS'); return false;" href="http://adsabs.harvard.edu/abs/1990MPLA....5.1223B"><span id="translatedtitle">S Matrix Proof of Consistency Condition Derived from Mixed <span class="hlt">Anomaly</span></span></a></p> <p><a target="_blank" href="http://adsabs.harvard.edu/abstract_service.html">NASA Astrophysics Data System (ADS)</a></p> <p>Bhansali, Vineer</p> <p></p> <p>For a confining quantum field theory with conserved current J and stress tensor T, the <JJJ> and <JTT> <span class="hlt">anomalies</span> computed in terms of elementary quanta must be precisely equal to the same <span class="hlt">anomalies</span> computed in terms of the exact physical spectrum if the conservation law corresponding to J is unbroken.

Until now, the quantity and quality of harvestable biomass from conservation grasslands in Minnesota, USA, was not known, and the factors that affect bioenergy <span class="hlt">potential</span> from these systems have not been identified. We measured biomass yield, theoretical ethanol conversion efficiency, and plant tissue nitrogen (N) as metrics of bioenergy <span class="hlt">potential</span> from mixed-species conservation grasslands harvested with commercial-scale equipment. With three years of data, we used mixed-effects models to determine factors that influence bioenergy <span class="hlt">potential</span>. Sixty conservation grassland plots, each about 8 ha in size, were distributed among three locations in Minnesota. Harvest treatments were applied annually in autumn as a completely randomized block design. Biomass yield ranged from 0.5 to 5.7 Mg ha−1. May precipitation increased biomass yield while precipitation in all other growing season months showed no affect. Averaged across all locations and years, theoretical ethanol conversion efficiency was 450 l Mg−1 and the concentration of plant N was 7.1 g kg−1, both similar to dedicated herbaceous bioenergy crops such as switchgrass. Biomass yield did not decline in the second or third year of harvest. Across years, biomass yields fluctuated 23% around the average. Surprisingly, forb cover was a better predictor of biomass yield than warm-season grass with a positive correlation with biomass yield in the south and a negative correlation at other locations. Variation in land ethanol yield was almost exclusively due to variation in biomass yield rather than biomass quality; therefore, efforts to increase biomass yield might be more economical than altering biomass composition when managing conservation grasslands for ethanol production. Our measurements of bioenergy <span class="hlt">potential</span>, and the factors that control it, can serve as parameters for assessing the economic viability of harvesting conservation grasslands for bioenergy.

They are seen in daily applications, such as telephone calls, retail sales, data center performance, and oil production operations. Many analysts want insight into the behavior of this data. They want to catch the exceptions in flight to reveal the causes of the <span class="hlt">anomalies</span> and to take immediate action. To guide the user in finding the <span class="hlt">anomalies</span> in the large data stream quickly, we derive a new automated neighborhood threshold marking technique, called <span class="hlt">Anomaly</span>Marker. This technique is built on cell-based data streams and user-defined thresholds. We extend the scope of the data points around the threshold to include the surrounding areas. The idea is to define a focus area (marked area) which enables users to (1) visually group the interesting data points related to the <span class="hlt">anomalies</span> (i.e., problems that occur persistently or occasionally) for observing their behavior; (2) discover the factors related to the <span class="hlt">anomaly</span> by visualizing the correlations between the problem attribute with the attributes of the nearby data items from the entire multi-dimensional data stream. Mining results are quickly presented in graphical representations (i.e., tooltip) for the user to zoom into the problem regions.

Solving this problem usually requires efficient local minimization techniques, i.e., iterative two-step methods that search first for a descent direction and then try to estimate the step width. The second step, the so called line search, typically uses polynomial interpolation schemes to estimate the next trial step. However, dependent on local properties of the objective function alternative schemes may be more appropriate especially if the objective function shows singularities or exponential behavior. As the choice of the best interpolation scheme cannot be made a priori, we propose a new consensus line search approach that performs several different interpolation schemes at each step and then decides which one is the most reliable at the current position. Although a naive consensus approach would lead to severe performance impacts, our method does not require additional evaluations of the <span class="hlt">energy</span> function, imposing only negligible computational overhead. Additionally, our method can be easily adapted to the local behavior of other objective functions by incorporating suitable interpolation schemes or omitting non-fitting schemes. The performance of our consensus line search approach has been evaluated and compared to established standard line search algorithms by minimizing the structures of a large set of molecules using different force fields. The proposed algorithm shows better performance in almost all test cases, i.e., it reduces the number of iterations and function and gradient evaluations, leading to significantly reduced run times.

This dissertation assesses heating, ventilating and air conditioning saving strategies based on <span class="hlt">energy</span> simulations with input parameters from actual retail buildings. The dissertation hypothesis is that "Retail store buildings will save a significant amount of <span class="hlt">energy</span> by (1) modifying ventilation rates, and/or (2) resetting set point temperatures. These strategies have shown to be beneficial in previous studies. As presented in the literature review, <span class="hlt">potential</span> <span class="hlt">energy</span> savings ranged from 0.5% to 30% without compromising indoor thermal comfort and indoor air quality. The retail store buildings can be ventilated at rates significantly lower than rates called for in the ASHRAE Standard 62.1-2010 while maintaining acceptable indoor air quality. Therefore, two dissertation objectives are addressed: (1) Investigate opportunities to reduce ventilation rates that do not compromise indoor air quality in retail stores located in Central Pennsylvania, (2) Investigate opportunities to increase (in summer) and decrease (in winter) set point temperatures that do not compromise thermal comfort. This study conducted experimental measurements of ventilation rates required to maintain acceptable air quality and indoor environmental conditions requirements for two retail stores using ASHRAE Standard 62.1_2012. More specifically, among other parameters, occupancy density, indoor and outdoor pollutant concentrations, and indoor temperatures were measured continuously for one week interval. One of these retail stores were tested four times for a yearlong time period. Pollutants monitored were formaldehyde, carbon dioxide, particle size distributions and concentrations, as well as total volatile organic compounds. As a part of the base protocol, the number of occupants in each store was hourly counted during the test, and the results reveal that the occupant densities were approximately 20% to 30% of that called by ASHRAE 62.1. Formaldehyde was the most important contaminant of concern in retail stores investigated. Both stores exceeded the most conservative health guideline for formaldehyde (OEHHA TWA REL = 7.3 ppb). This study found that source removal and reducing the emission rate, as demonstrated in retail stores sampled in this study, is a viable strategy to meet the health guideline. Total volatile compound were present in retail stores at low concentrations well below health guidelines suggested by Molhave (1700microg /m 2) and Bridges (1000 microg /m2). Based on these results and through mass--balance modeling, different ventilation rate reduction scenarios were proposed, and for these scenarios the differences in <span class="hlt">energy</span> consumption were estimated. Findings of all phases of this desertion have contributed to understanding (a) the trade-off between <span class="hlt">energy</span> savings and ventilation rates that do not compromise indoor air quality, and (b) the trade-off between <span class="hlt">energy</span> savings and resets of indoor air temperature that do not compromise thermal comfort. Two models for retail stores were built and calibrated and validated against actual utility bills. <span class="hlt">Energy</span> simulation results indicated that by lowering the ventilation rates from measured and minimum references would reduce natural gas <span class="hlt">energy</span> use by estimated values of 6% to 19%. Also, this study found that the electrical cooling <span class="hlt">energy</span> consumption was not significantly sensitive to different ventilation rates. However, increasing indoor air temperature by 3°C in summer had a significant effect on the <span class="hlt">energy</span> savings. In winter, both <span class="hlt">energy</span> savings strategies, ventilation reduction and decrease in set points, had a significant effect on natural gas consumption. Specially, when the indoor air temperature 21°C was decreased to 19.4°C with the same amount of ventilation rate of Molhaves guideline for both cases. Interestingly, the temperature of 23.8°C (75°F), which is the lowest value of ASHRAE 55 thermal comfort for sedentary people (cashiers) and the highest value for thermal comfort adjustments due to activity level (customers and workers) that are calculated by using empirical equation, was the optimum temperature for sedentary and active people in Retail store buildings.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://www.osti.gov/scitech/biblio/211798','SCIGOV-STC'); return false;" href="http://www.osti.gov/scitech/biblio/211798"><span id="translatedtitle">Expert system to determine <span class="hlt">energy</span>-saving retrofit <span class="hlt">potential</span> of public buildings</span></a></p> <p><a target="_blank" href="http://www.osti.gov/scitech">SciTech Connect</a></p> <p>Gatton, T.M.; Lee, Y.; Beaudry, M.A.; Jaeger, S.</p> <p>1995-12-31</p> <p>Due to economic and environmental constraints, it is important to maintain good and efficient working standards for building <span class="hlt">energy</span> systems.

We argue that there are two basic phenomena, which are related to chiral <span class="hlt">anomaly</span> in Weyl metals: anomalous Hall effect (AHE) and chiral magnetic effect (CME). While AHE is in principle present in any ferromagnetic metal, we demonstrate that a magnetic Weyl metal is distinguished from an ordinary ferromagnetic metal by the absence of the extrinsic and the Fermi surface part of the intrinsic contributions to the AHE, as long as the Fermi <span class="hlt">energy</span> is sufficiently close to the Weyl nodes. The AHE in a Weyl metal is thus shown to be a purely intrinsic, universal property, fully determined by the location of the Weyl nodes in the first Brillouin zone. In other words, a ferromagnetic Weyl metal may be thought of as the only example of a ferromagnetic metal with a purely intrinsic AHE. We further develop a fully microscopic theory of diffusive magnetotransport in Weyl metals. We derive coupled diffusion equations for the total and axial (i.e. node-antisymmetric) charge densities and show that chiral <span class="hlt">anomaly</span> manifests as a magnetic-field-induced coupling between them. We demonstrate that an experimentally-observable consequence of CME in magnetotransport in Weyl metals is a quadratic negative magnetoresistance, which will dominate all other contributions to magnetoresistance under certain conditions and may be regarded as a smoking-gun transport characteristic, unique to Weyl metals.

While AHE is in principle present in any ferromagnetic metal, we demonstrate that a magnetic Weyl metal is distinguished from an ordinary ferromagnetic metal by the absence of the extrinsic and the Fermi surface part of the intrinsic contributions to the AHE, as long as the Fermi <span class="hlt">energy</span> is sufficiently close to the Weyl nodes. The AHE in a Weyl metal is thus shown to be a purely intrinsic, universal property, fully determined by the location of the Weyl nodes in the first Brillouin zone. In other words, a ferromagnetic Weyl metal may be thought of as the only example of a ferromagnetic metal with a purely intrinsic AHE. We further develop a fully microscopic theory of diffusive magnetotransport in Weyl metals. We derive coupled diffusion equations for the total and axial (i.e. node-antisymmetric) charge densities and show that chiral <span class="hlt">anomaly</span> manifests as a magnetic-field-induced coupling between them. We demonstrate that an experimentally-observable consequence of CME in magnetotransport in Weyl metals is a quadratic negative magnetoresistance, which will dominate all other contributions to magnetoresistance under certain conditions and may be regarded as a smoking-gun transport characteristic, unique to Weyl metals.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://ntrs.nasa.gov/search.jsp?R=19820034092&hterms=Pollution+turbines&qs=N%3D0%26Ntk%3DAll%26Ntx%3Dmode%2Bmatchall%26Ntt%3DPollution%2Bturbines','NASA-TRS'); return false;" href="http://ntrs.nasa.gov/search.jsp?R=19820034092&hterms=Pollution+turbines&qs=N%3D0%26Ntk%3DAll%26Ntx%3Dmode%2Bmatchall%26Ntt%3DPollution%2Bturbines"><span id="translatedtitle"><span class="hlt">Energy</span> <span class="hlt">potential</span> and early operational experience for large wind turbines</span></a></p> <p><a target="_blank" href="http://ntrs.nasa.gov/search.jsp">NASA Technical Reports Server (NTRS)</a></p> <p>Robbins, W.

NASA has developed nine large windpowered generators, of 100 kW, 200 kW, 2 MW, and 2.5 MW capacities, with rotors 100-300 ft in diameter, and all with horizontal axes. Approximately 214,000 sq miles of the U.S. have been determined as having substantial wind regimes and terrain suitable for large wind turbine siting. This translates into 340,000 Mod 2 (2.5 MW) wind turbines producing 4.9 quads of electricity annually, equivalent to saving 2.5 billion barrels of oil/yr. The cost of electricity is seen as the critical factor in utility acceptance of large wind turbines, and the Mod 2 machines are noted to achieve the 2-4 cents/kWh (1977 dollars) COE which is necessary. Problems such as pollution, including visual, auditory, EM, and land use difficulties are considered, and solutions are indicated.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://www.ncbi.nlm.nih.gov/pubmed/20131763','PUBMED'); return false;" href="http://www.ncbi.nlm.nih.gov/pubmed/20131763"><span id="translatedtitle"><span class="hlt">Potential</span> <span class="hlt">energy</span> surfaces fitted by artificial neural networks.</span></a></p> <p><a target="_blank" href="http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?DB=pubmed">PubMed</a></p> <p>Handley, Chris M; Popelier, Paul L A</p> <p>2010-03-18</p> <p>Molecular mechanics is the tool of choice for the modeling of systems that are so large or complex that it is impractical or impossible to model them by ab initio methods.

The interactions within force fields are represented by a number of functions. Some interactions are well understood and can be represented by simple mathematical functions while others are not so well understood and their functional form is represented in a simplistic manner or not even known. In the last 20 years there have been the first examples of a new design ethic, where novel and contemporary methods using machine learning, in particular, artificial neural networks, have been used to find the nature of the underlying functions of a force field.

To determine how the latter can affect the crack equilibrium and growth, a model of a structured linearly elastic body is introduced, consisting of two equal symmetrically arranged layers (or half-planes) connected by an interface as a prospective crack path. The interface comprises a discrete set of elastic bonds. In the initial state, the bonds are assumed to be stressed in such a way that tensile and compressive forces of the same value alternate. In the general considerations, the layers are assumed to be of an unspecified periodic structure, where such self-equilibrated stresses may also exist. A two-line chain and a lattice are examined as the specified structure. We consider the states of the body-with-a-crack under such microlevel stresses (MS) and under a combined action of the remote forces and MS. Analytical solutions to the considered problems are presented based on the introduction of a selective discrete transform. We demonstrate that MS can increase as well as decrease the crack resistance depending on the internal <span class="hlt">energy</span> level. We also discuss different scenarios of the crack growth.

Hood region in the last 15 m.y. shows a slow migration of six to eight volcanic centers from a position about 20 km west of Mt. Hood to the most recent volcanic center in the series. Cutting across the entire Mt. Hood region and most of the Pacific Northwest is a set of northwest-southeast right-lateral strike-slip faults. These are numerous around Mt. Hood, but the offset of any single fault is small (a few meters) and in some cases vertical. These faults are also young and indicate east-west extension and north-south compression. An older and probably inactive set of northeast-southwest folds and thrust faults is evident in the region, particularly in the Miocene Columbia River Basalt Group. These may be related to a long history of north-south compression. The volcanic history and structure are presumably a result of subduction of the Juan de Fuca plate beneath the North American plate. This subduction is oblique, leading to a substantial component of right-lateral motion which, in turn, leads to north-south compression in the Pacific Northwest. Crustal thinning associated with volcanism has resulted in an elevated geothermal gradient around Mt. Hood. This high gradient makes it possible to tap water in excess of 80 /sup 0/C within 1500 m of the surface. If these thermal waters can be produced in large volumes, they might provide a substantial amount of economically competitive <span class="hlt">energy</span> for space heating and industrial processes, in the region adjacent to the Cascades. A simple geothermal resource calculation shows that a 1000 km/sup 2/ area around Mt. Hood could produce beneficial heat which, if supplied by electricity, would require over 1000 MW for 30 years.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://www.ncbi.nlm.nih.gov/pubmed/26584123','PUBMED'); return false;" href="http://www.ncbi.nlm.nih.gov/pubmed/26584123"><span id="translatedtitle">Intermolecular Contact <span class="hlt">Potentials</span> for Protein-Protein Interactions Extracted from Binding Free <span class="hlt">Energy</span> Changes upon Mutation.</span></a></p> <p><a target="_blank" href="http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?DB=pubmed">PubMed</a></p> <p>Moal, Iain H; Fernandez-Recio, Juan</p> <p>2013-08-13</p> <p>Understanding and predicting the energetics of protein-protein interactions is fundamental to the structural modeling of protein complexes.

At present, global bio-<span class="hlt">energy</span> use amounts to approximately 50 EJ/yr, about 10% of humanity's primary <span class="hlt">energy</span> supply. We here review recent literature on the amount of bio-<span class="hlt">energy</span> that could be supplied globally in 2050, given current expectations on technology, food demand and environmental targets (‘technical potential’). Recent studies span a large range of global bio-<span class="hlt">energy</span> <span class="hlt">potentials</span> from ≈30 to over 1000 EJ/yr. In our opinion, the high end of the range is implausible because of (1) overestimation of the area available for bio-<span class="hlt">energy</span> crops due to insufficient consideration of constraints (e.g., area for food, feed or nature conservation) and (2) too high yield expectations resulting from extrapolation of plot-based studies to large, less productive areas.

Results from the LSND and MiniBooNE short-baseline νe /νe appearance experiments show <span class="hlt">anomalies</span> which cannot be described by oscillations between the three standard model neutrinos (the ``LSND <span class="hlt">anomaly</span>''). In addition, a re-analysis of the anti-neutrino flux produced by nuclear power reactors has led to an apparent deficit in νe event rates in a number of reactor experiments (the ``reactor <span class="hlt">anomaly</span>''). Similarly, calibration runs using 51Cr and 37Ar radioactive sources in the Gallium solar neutrino experiments GALLEX and SAGE have shown an unexplained deficit in the electron neutrino event rate over very short distances (the ``Gallium <span class="hlt">anomaly</span>''). The puzzling results from these experiments, which together may suggest the existence of physics beyond the Standard Model and hint at exciting new physics, including the possibility of additional low-mass sterile neutrino states, have raised the interest in the community for new experimental efforts that could eventually solve this puzzle. Definitive evidence for sterile neutrinos would be a revolutionary discovery, with implications for particle physics as well as cosmology. Proposals to address these signals by employing accelerator, reactor and radioactive source experiments are in the planning stages or underway worldwide.

Utility-scale solar <span class="hlt">energy</span> (USSE; i.e., > 1 MW) necessitates large quantities of space making the efficient use of land for USSE development critical to realizing its full <span class="hlt">potential</span>. However, studies elucidating the interaction between land-use and utility-scale solar <span class="hlt">energy</span> (USSE) are limited. In this study, we assessed 1) the theoretical and technical <span class="hlt">potential</span> of terrestrial-based USSE systems, and 2) land-use and land-cover change impacts from actual USSE installations (> 20 MW; planned, under construction, operating), using California as a case study due to its early adoption of renewable <span class="hlt">energy</span> systems, unique constraints on land availability, immense <span class="hlt">energy</span> demand, and vast natural resources. We used topo-climatic (e.g., slope, irradiance), infrastructural (e.g., proximity to transmission lines), and ecological constraints (e.g., threatened and endangered species) to determine highly favorable, favorable, and unfavorable locations for USSE and to assess its technical <span class="hlt">potential</span>. We found that the theoretical <span class="hlt">potential</span> of photovoltaic (PV) and concentrating solar power (CSP) in California is 26,097 and 29,422 kWh/m2/day, respectively. We identified over 150 planned, under construction, and operating USSE installations in California, ranging in size from 20 to 1,000 MW. Currently, 29% are located on shrub- and scrublands, 23% on cultivated crop land, 13% on pasture/hay areas, 11% on grassland/herbaceous and developed open space, and 7% in the built environment. Understanding current land-use decisions of USSE systems and assessing its future <span class="hlt">potential</span> can be instructive for achieving land, <span class="hlt">energy</span>, and environmental compatibility, especially for other global regions that share similar resource demands and limitations.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://www.osti.gov/scitech/biblio/20695567','SCIGOV-STC'); return false;" href="http://www.osti.gov/scitech/biblio/20695567"><span id="translatedtitle">Dynamic polarization <span class="hlt">potentials</span> for the halo nucleus {sup 6}He in medium-<span class="hlt">energy</span> elastic scattering</span></a></p> <p><a target="_blank" href="http://www.osti.gov/scitech">SciTech Connect</a></p> <p>Abu-Ibrahim, B.; Suzuki, Y.</p> <p>2004-07-01</p> <p>We study dynamic polarization <span class="hlt">potentials</span> for a halo nucleus {sup 6}He scattered by a {sup 12}C target in the eikonal approximation.

The relationship between the ENSO and the climate of China was revealed. The main results indicated the following: 1) there are two ENSO modes acting on the subsurface tropical Pacific. The first mode is related to the mature phase of ENSO, which mainly appears during winter. The second mode is associated with a transition stage of the ENSO developing or decaying, which mainly occurs during summer; 2) during the mature phase of El Nio, the meridionality of the atmosphere in the mid-high latitude increases, the Aleutian low and high pressure ridge over Lake Baikal strengthens, northerly winds prevail in northern China, and precipitation in northern China decreases significantly. The ridge of the Ural High strengthens during the decaying phase of El Nio, as atmospheric circulation is sustained during winter, and the northerly wind <span class="hlt">anomaly</span> appears in northern China during summer. Due to the ascending branch of the Walker circulation over the western Pacific, the western Pacific Subtropical High becomes weaker, and south-southeasterly winds prevail over southern China. As a result, less rainfall occurs over northern China and more rainfall over the Changjiang River basin and the southwestern and eastern region of Inner Mongolia. The flood disaster that occurred south of Changjiang River can be attributed to this. The La Nia event causes an opposite, but weaker effect; 3) the ENSO cycle can influence climate <span class="hlt">anomalies</span> within China via zonal and meridional heat transport. This is known as the "atmospheric-bridge", where the <span class="hlt">energy</span> <span class="hlt">anomaly</span> within the tropical Pacific transfers to the mid-high latitude in the northern Pacific through Hadley cells and Rossby waves, and to the western Pacific-eastern Indian Ocean through Walker circulation. This research also discusses the special air-sea boundary processes during the ENSO events in the tropical Pacific, and indicates that the influence of the subsurface water of the tropical Pacific on the atmospheric circulation may be realized through the sea surface temperature <span class="hlt">anomalies</span> of the mixed water, which contact the atmosphere and transfer the anomalous heat and moisture to the atmosphere directly. Moreover, the reason for the heavy flood within the Changjiang River during the summer of 1998 is reviewed in this paper.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://www.osti.gov/scitech/servlets/purl/861207','SCIGOV-STC'); return false;" href="http://www.osti.gov/scitech/servlets/purl/861207"><span id="translatedtitle">A New Methodology for Early <span class="hlt">Anomaly</span> Detection of BWR Instabilities</span></a></p> <p><a target="_blank" href="http://www.osti.gov/scitech">SciTech Connect</a></p> <p>Ivanov, K.

The technical approach relies on suppression of <span class="hlt">potential</span> power oscillations in BWRs by detecting small <span class="hlt">anomalies</span> at an early stage and taking appropriate prognostic actions based on an anticipated operation schedule. The research utilizes a model of coupled (two-phase) thermal-hydraulic and neutron flux dynamics, which is used as a generator of time series data for <span class="hlt">anomaly</span> detection at an early stage. The model captures critical nonlinear features of coupled thermal-hydraulic and nuclear reactor dynamics and (slow time-scale) evolution of the <span class="hlt">anomalies</span> as non-stationary parameters. The time series data derived from this nonlinear non-stationary model serves as the source of information for generating the symbolic dynamics for characterization of model parameter changes that quantitatively represent small <span class="hlt">anomalies</span>. The major focus of the presented research activity was on developing and qualifying algorithms of pattern recognition for power instability based on <span class="hlt">anomaly</span> detection from time series data, which later can be used to formulate real-time decision and control algorithms for suppression of power oscillations for a variety of anticipated operating conditions. The research being performed in the framework of this project is essential to make significant improvement in the capability of thermal instability analyses for enhancing safety, availability, and operational flexibility of currently operating and next generation BWRs.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://www.ncbi.nlm.nih.gov/pubmed/26980401','PUBMED'); return false;" href="http://www.ncbi.nlm.nih.gov/pubmed/26980401"><span id="translatedtitle">Density and structural <span class="hlt">anomalies</span> in soft-repulsive dimeric fluids.</span></a></p> <p><a target="_blank" href="http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?DB=pubmed">PubMed</a></p> <p>Munaó, Gianmarco; Saija, Franz</p> <p>2016-04-14</p> <p>We report Monte Carlo results for the fluid structure of a system of dimeric particles interacting via a core-softened <span class="hlt">potential</span>.

The study utilizes World-wide GPS Receiver Network Total Electron Content (TEC) data spanning 13 years (2001-2014) and focuses on the changes in the equatorial ionization <span class="hlt">anomaly</span> the Western hemisphere. TEC is highly variable due to the influences of solar flux, geomagnetic activity, and seasonal variation and these influences are removed by the use of model. This empirical TEC model is a combination of linear dependencies of solar flux (F10.7) and geomagnetic activity (Ap3) with a third degree polynomial dependency for day-of-year (DOY). With such dependencies removed, the remaining TEC variation could be resolved and attributed to an appropriate mechanism. Lunar phase and apside was investigated in particular, especially the new and full moon phases during perigees when tidal forcing would be most powerful. Lunar tidal forcing on planetary waves is also examined as being physically responsible for setting up conditions that may give rise to SSWs and ionospheric <span class="hlt">anomalies</span>. Preliminary results suggest that such <span class="hlt">anomalies</span> may be enhanced in intensity during the full or new moon and even more so during perigee by different amounts depending on whether the SSW is a major (40-60%) or minor (20-45%) event.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://adsabs.harvard.edu/abs/1995sccm.conf...13M','NASAADS'); return false;" href="http://adsabs.harvard.edu/abs/1995sccm.conf...13M"><span id="translatedtitle">Numerical <span class="hlt">anomalies</span> mimicking physical effects</span></a></p> <p><a target="_blank" href="http://adsabs.harvard.edu/abstract_service.html">NASA Astrophysics Data System (ADS)</a></p> <p>Menikoff, R.</p> <p></p> <p>Numerical simulations of flows with shock waves typically use finite-difference shock-capturing algorithms. These algorithms give a shock a numerical width in order to generate the entropy increase that must occur across a shock wave. For algorithms in conservation form, steady-state shock waves are insensitive to the numerical dissipation because of the Hugoniot jump conditions. However, localized numerical errors occur when shock waves interact. Examples are the 'excess wall heating' in the Noh problem (shock reflected from rigid wall), errors when a shock impacts a material interface or an abrupt change in mesh spacing, and the start-up error from initializing a shock as a discontinuity. This class of <span class="hlt">anomalies</span> can be explained by the entropy generation that occurs in the transient flow when a shock profile is formed or changed. The entropy error is localized spatially but under mesh refinement does not decrease in magnitude. Similar effects have been observed in shock tube experiments with partly dispersed shock waves. In this case, the shock has a physical width due to a relaxation process. An entropy <span class="hlt">anomaly</span> from a transient shock interaction is inherent in the structure of the conservation equations for fluid flow. The <span class="hlt">anomaly</span> can be expected to occur whenever heat conduction can be neglected and a shock wave has a non-zero width, whether the width is physical or numerical. Thus, the numerical <span class="hlt">anomaly</span> from an artificial shock width mimics a real physical effect.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://cfpub.epa.gov/si/si_public_record_report.cfm?dirEntryId=233766&keyword=calcium+AND+carbonate&actType=&TIMSType=+&TIMSSubTypeID=&DEID=&epaNumber=&ntisID=&archiveStatus=Both&ombCat=Any&dateBeginCreated=&dateEndCreated=&dateBeginPublishedPresented=&dateEndPublishedPresented=&dateBeginUpdated=&dateEndUpdated=&dateBeginCompleted=&dateEndCompleted=&personID=&role=Any&journalID=&publisherID=&sortBy=revisionDate&count=50&CFID=59515736&CFTOKEN=82707312','EPA-EIMS'); return false;" href="http://cfpub.epa.gov/si/si_public_record_report.cfm?dirEntryId=233766&keyword=calcium+AND+carbonate&actType=&TIMSType=+&TIMSSubTypeID=&DEID=&epaNumber=&ntisID=&archiveStatus=Both&ombCat=Any&dateBeginCreated=&dateEndCreated=&dateBeginPublishedPresented=&dateEndPublishedPresented=&dateBeginUpdated=&dateEndUpdated=&dateBeginCompleted=&dateEndCompleted=&personID=&role=Any&journalID=&publisherID=&sortBy=revisionDate&count=50&CFID=59515736&CFTOKEN=82707312"><span id="translatedtitle">Coral can have growth <span class="hlt">anomalies</span></span></a></p> <p><a target="_blank" href="http://oaspub.epa.gov/eims/query.page">EPA Science Inventory</a></p> <p></p> <p></p> <p>Coral growth <span class="hlt">anomalies</span> (GAs) are changes in the coral cells that deposit the calcium carbonate skeleton.

T.; Anderson, M. C.; Yilmaz, M. T.</p> <p>2014-12-01</p> <p>Atmospheric processes, especially those that occur in the surface and boundary layer, are significantly impacted by soil moisture (SM). Due to the observational gaps in the ground-based monitoring of SM, methodologies have been developed to monitor SM from satellite platforms. While many have focused on microwave methods, observations of thermal infrared land surface temperature (LST) also provides a means of providing SM information. One particular TIR SM method exploits surface flux predictions retrieved from the Atmosphere Land Exchange Inverse (ALEXI) model. ALEXI uses a time-differential measurement of morning LST rise to diagnose the partitioning of net radiation into surface <span class="hlt">energy</span> fluxes. Here an analysis will be presented to study relationships between three SM products during a multi-year period (2000-2013) from an active/passive microwave dataset (ECV), a TIR-based model (ALEXI), and a land surface model (Noah) over the CONUS. Additionally, all three will be compared against in-situ SM observations from the North American Soil Moisture Database. The second analysis will focus on the use of ALEXI towards diagnosing SM source/sink processes. Traditional soil water balance modeling is based on one-dimensional (vertical-only) water flow, free drainage at the bottom of the soil column, and neglecting ancillary inputs due to processes such as irrigation. However, recent work has highlighted the importance of secondary water source (e.g., irrigation, groundwater extraction, inland wetlands, lateral flows) and sink (e.g., tile drainage in agricultural areas) processes on the partitioning of evaporative and sensible heat fluxes. ALEXI offers a top-down approach for mapping areas where SM source/sink processes have a significant impact on the surface <span class="hlt">energy</span> balance. Here we present an index, ASSET, that is based on comparisons between ALEXI latent heat flux (LE) estimates and LE predicted by a free-drainage prognostic LSM lacking irrigation, groundwater and tile drainage modules. ASSET is compared to existing maps of estimated groundwater depth, open water fraction, and irrigated area to provide a preliminary evaluation of the index as a diagnostic tool for evaluating the impact of SM source/sink processes not captured by traditional one-dimensional water balance models.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://www.osti.gov/scitech/servlets/purl/10165731','SCIGOV-STC'); return false;" href="http://www.osti.gov/scitech/servlets/purl/10165731"><span id="translatedtitle"><span class="hlt">Energy</span> flux and hydrogeology of thermal <span class="hlt">anomalies</span> in the Gulf of Mexico Basin -- South Texas example.
