  1. Automated grading of homework assignments and tests in introductory and intermediate statistics courses using active server pages.

    PubMed

    Stockburger, D W

    1999-05-01

    Active server pages permit a software developer to customize the Web experience for users by inserting server-side script and database access into Web pages. This paper describes applications of these techniques and provides a primer on the use of these methods. Applications include a system that generates and grades individualized homework assignments and tests for statistics students. The student accesses the system as a Web page, prints out the assignment, does the assignment, and enters the answers on the Web page. The server, running on NT Server 4.0, grades the assignment, updates the grade book (on a database), and returns the answer key to the student. PMID:10495807

    2000-07-01

    These twelve lessons, and an introductory lesson, are tutorials in basic topics of introductory chemistry. They are suitable for school use, individual study, or distance learning. They are particularly valuable as review material for students in more advanced courses who may have been away from the subject for some time. They contain a great variety of problems and exercises driven by random-number generators, so that the same problem never repeats exactly. The lessons are, for the most part, Socratic dialogues in which the student is required to answer questions and perform simulated experiments in order to discover chemical principles. They are organized in an intuitive chapter and page structure. One may move readily around each lesson. There are many on-screen facilities such as help, data tables, and a calculator.

    2012-04-01

    A catalog for northeast India and the adjoining region for the period 1897-2009 with 4,497 earthquakes events is compiled for homogenization to moment magnitude M w,GCMT in the magnitude range 3-8.7. Relations for conversion of m b and M s magnitudes to M w,GCMT are derived using three different methods, namely, linear standard regression, inverted standard regression (ISR) and orthogonal standard regression (OSR), for different magnitude ranges based on events data for the catalog period 1976-2006. The OSR relations for M s to M w,GCMT conversion derived in this paper have significantly lower errors in regression parameters compared to the relations reported in other studies. Since the number of events with magnitude ≥7 for this region is scanty, we, therefore, considered whole India region to obtain the regression relationships between M w,GCMT and M s,ISC. A relationship between M w,GCMT and M w,NEIC is also obtained based on 17 events for the range 5.2 ≤ magnitude ≤ 6.6. A unified homogeneous catalog prepared using the conversion relations derived in this paper can serve as a reference catalog for seismic hazard assessment studies in northeast India and the adjoining region.

    Kerley, James J. (Inventor); Eklund, Wayne D. (Inventor)

    1992-01-01

    A device for holding reading materials for use by readers without arm mobility is presented. The device is adapted to hold the reading materials in position for reading with the pages displayed to enable turning by use of a rubber tipped stick that is held in the mouth and has a pair of rectangular frames. The frames are for holding and positioning the reading materials opened in reading posture with the pages displayed at a substantially unobstructed sighting position for reading. The pair of rectangular frames are connected to one another by a hinge so the angle between the frames may be varied thereby varying the inclination of the reading material. A pair of bent spring mounted wires for holding opposing pages of the reading material open for reading without substantial visual interference of the pages is mounted to the base. The wires are also adjustable to the thickness of the reading material and have a variable friction adjustment. This enables the force of the wires against the pages to be varied and permits the reader to manipulate the pages with the stick.

  6. Mathematization in introductory physics

    NASA Astrophysics Data System (ADS)

    Brahmia, Suzanne M.

    Mathematization is central to STEM disciplines as a cornerstone of the quantitative reasoning that characterizes these fields. Introductory physics is required for most STEM majors in part so that students develop expert-like mathematization. This dissertation describes coordinated research and curriculum development for strengthening mathematization in introductory physics; it blends scholarship in physics and mathematics education in the form of three papers. The first paper explores mathematization in the context of physics, and makes an original contribution to the measurement of physics students' struggle to mathematize. Instructors naturally assume students have a conceptual mastery of algebra before embarking on a college physics course because these students are enrolled in math courses beyond algebra. This paper provides evidence that refutes the validity of this assumption and categorizes some of the barriers students commonly encounter with quantification and representing ideas symbolically. The second paper develops a model of instruction that can help students progress from their starting points to their instructor's desired endpoints. Instructors recognize that the introductory physics course introduces new ideas at an astonishing rate. More than most physicists realize, however, the way that mathematics is used in the course is foreign to a large portion of class. This paper puts forth an instructional model that can move all students toward better quantitative and physical reasoning, despite the substantial variability of those students' initial states. The third paper describes the design and testing of curricular materials that foster mathematical creativity to prepare students to better understand physics reasoning. Few students enter introductory physics with experience generating equations in response to specific challenges involving unfamiliar quantities and units, yet this generative use of mathematics is typical of the thinking involved in

  7. CTAB-PAGE.

    PubMed

    Simpson, Richard J

    2010-04-01

    Although SDS-PAGE is the method of choice for most denaturing gel electrophoresis procedures, the anionic detergent SDS still presents some drawbacks. For example, SDS forms crystals at low temperatures and, in some cases, causes proteins to aggregate or precipitate. In addition, some proteins are not well-resolved in SDS gels or may migrate anomalously. In these situations, the use of a cationic detergent for PAGE offers an alternative approach. The system described in this protocol uses the cationic detergent cetyltrimethyl ammonium bromide (CTAB) and includes a stacking gel based on the zwitterion arginine (used as a stacking agent) and tricine (N-tris[hydroxymethyl]-methylglycine) used as a counterion and buffer. Some proteins separated on the CTAB electrophoresis system retain their native enzymatic activity, provided the samples are prepared without boiling and without the addition of a reducing agent.

  8. Bootstrapping structured page segmentation

    NASA Astrophysics Data System (ADS)

    Ma, Huanfeng; Doermann, David S.

    2003-01-01

    In this paper, we present an approach to the bootstrap learning of a page segmentation model. The idea evolves from attempts to segment dictionaries that often have a consistent page structure, and is extended to the segmentation of more general structured documents. In cases of highly regular structure, the layout can be learned from examples of only a few pages. The system is first trained using a small number of samples, and a larger test set is processed based on the training result. After making corrections to a selected subset of the test set, these corrected samples are combined with the original training samples to generate bootstrap samples. The newly created samples are used to retrain the system, refine the learned features and resegment the test samples. This procedure is applied iteratively until the learned parameters are stable. Using this approach, we do not need to initially provide a large set of training samples. We have applied this segmentation to many structured documents such as dictionaries, phone books, spoken language transcripts, and obtained satisfying segmentation performance.

  10. Multiplex PageRank.

    PubMed

    Halu, Arda; Mondragón, Raúl J; Panzarasa, Pietro; Bianconi, Ginestra

    2013-01-01

    Many complex systems can be described as multiplex networks in which the same nodes can interact with one another in different layers, thus forming a set of interacting and co-evolving networks. Examples of such multiplex systems are social networks where people are involved in different types of relationships and interact through various forms of communication media. The ranking of nodes in multiplex networks is one of the most pressing and challenging tasks that research on complex networks is currently facing. When pairs of nodes can be connected through multiple links and in multiple layers, the ranking of nodes should necessarily reflect the importance of nodes in one layer as well as their importance in other interdependent layers. In this paper, we draw on the idea of biased random walks to define the Multiplex PageRank centrality measure in which the effects of the interplay between networks on the centrality of nodes are directly taken into account. In particular, depending on the intensity of the interaction between layers, we define the Additive, Multiplicative, Combined, and Neutral versions of Multiplex PageRank, and show how each version reflects the extent to which the importance of a node in one layer affects the importance the node can gain in another layer. We discuss these measures and apply them to an online multiplex social network. Findings indicate that taking the multiplex nature of the network into account helps uncover the emergence of rankings of nodes that differ from the rankings obtained from one single layer. Results provide support in favor of the salience of multiplex centrality measures, like Multiplex PageRank, for assessing the prominence of nodes embedded in multiple interacting networks, and for shedding a new light on structural properties that would otherwise remain undetected if each of the interacting networks were analyzed in isolation.

    Langbeheim, Elon; Livne, Shelly; Safran, Samuel A.; Yerushalmi, Edit

    2012-01-01

    We describe an elective course on soft matter at the level of introductory physics. Soft matter physics serves as a context that motivates the presentation of basic ideas in statistical thermodynamics and their applications. It also is an example of a contemporary field that is interdisciplinary and touches on chemistry, biology, and physics. We outline a curriculum that uses the lattice gas model as a quantitative and visual tool, initially to introduce entropy, and later to facilitate the calculation of interactions. We demonstrate how free energy minimization can be used to teach students to understand the properties of soft matter systems such as the phases of fluid mixtures, wetting of interfaces, self-assembly of surfactants, and polymers. We discuss several suggested activities in the form of inquiry projects which allow students to apply the concepts they have learned to experimental systems.

    2005-12-01

    Geophysical concepts are challenging to teach at introductory levels, because students need to understand both the underlying physics and its geological application. To address this, our introductory courses include class demonstrations and experiments to demonstrate underlying physical principles and their geological applications. Demonstrations and experiments have several advantages over computer simulations. First, computer simulations "work" even if the basic principle is wrong. In contrast, simple demonstrations show that a principle is physically correct, rather than a product of computer graphics. Second, many students are unfamiliar with once-standard experiments demonstrating ideas of classical physics used in geophysics. Demonstrations are chosen that we consider stimulating, relevant, inexpensive, and easy to conduct in a non-lab classroom. These come in several groups. Many deal with aspects of seismic waves, using springs, light beams, and other methods such as talking from outside the room to illustrate the frequency dependence of diffraction (hearing but not seeing around a corner). Others deal with heat and mass transfer, such as illustrating fractional crystallization with apple juice and the surface/volume effect in planetary evolution with ice. Plate motions are illustrated with paper cutouts showing effects like motion on transform faults and how the Euler vector geometry changes a plate boundary from spreading, to strike-slip, to convergence along the Pacific-North America boundary from the Gulf of California to Alaska. Radioactive decay is simulated by having the class rise and sit down as a result of coin flips (one tail versus two gives different decay rates and hence half lives). This sessions' goal of exchanging information about demonstrations is an excellent idea: some of ours are described on http://www.earth.nwu.edu/people/seth/202.

    The investigations were carried out in Agroecological Landscape Park in Turew (40 km South-West of Poznań). Intensively agricultural is observed in this region. Characteristic features of this landscape are shelterbelts created in the XIX century by general Dezydery Chlapowski. All shelterbelts and adjoining cultivated fields were introduced on Hapludalfs soils. Three shelterbelts and adjoining cultivated fields were selected for this experiment. Two of them were created approximately 200 years ago. The first shelterbelt consists mainly of Robinia pseudoacacia and small admixture Quercus robur and Quercus petraea. The second one consists of Crataegus monogyna. The third one - a young shelterbelt was created in 1993 and consists of several species of plants such as: Quercus petraea and Quercus robur, Larix deciduas, Pinus sylvestris, Sorbus aucuparia, Sorbus intermedia, Tilia cordata and some other tree species. On soils were determinated: activity of nitrate reductase, activity of peroxidase, activity of urease and activity of xantine oxidase, total iron, Fe+3, Fe+2, total nitrogen, N-NH4+, N-NO3-, total organic carbon (TOC), dissolved organic carbon (DOC), current N2O, N2 and CH4 flux rates, and pH (in 1M KCl). The contents of total organic carbon, dissolved organic carbon, total nitrogen, N-NO3- and N-NH4+ were higher in the soil under old shelterbelts (Robinia pseudoacacia and Crataegus monogyna) than under young one. It points out the highest accumulation of organic matter in soils under two old shelterbelts. The same also applied to the current N2O and N2 fluxes. Unlike this CH4exchange was just low everywhere. Nitrate reductase, urease, xantine oxidase and peroxidase activities participates in the cycle of nitrogen and are sensitive on redox potential in soil. The highest activity of nitrate reductase and xantine oxidase activity were observed in young shelterbelt. Activity of urease and activity of peroxidase were higher under two old shelterbelts Robinia

    2009-04-01

    The shelterbelts perform more than twenty different functions favorable to the environment, human economy, health and culture. The most important for agricultural landscape is increase of water retention, purification of ground waters and prevent of pollution spread in the landscape, restriction of wind and water erosion effects, isolation of polluting elements in the landscape, preservation of biological diversity in agricultural areas and mitigation of effects of unfavorable climatic phenomena. Denitrification is defined as the reduction of nitrate or nitrite coupled to electron transport phosphorylation resulting in gaseous N either as molecular N2 or as an oxide of N. High content of moisture, low oxygen, neutral and basic pH favour the denitrification. Nitrate reductase is an important enzyme involved in the process of denitrification. The reduction of nitrate to nitrite is catalyzed by nitrate reductase. Nitrite reductase is catalyzed reduction nitrite to nitrous oxide. The conversion of N2O to N2 is catalyzed by nitrous oxide reductase. This process leads to the lost of nitrogen in soil mainly in the form of N2 and N2O. Nitrous oxide is a greenhouse gas which cause significant depletion of the Earth's stratospheric ozone layer. The investigations were carried out in Dezydery Chlapowski Agroecological Landscape Park in Turew (40 km South-West of Poznań, West Polish Lowland). Our investigations were focused on the soils under Robinia pseudacacia shelterbelt and in adjoining cultivated field. The afforestation was created 200 years ago and it is consist of mainly Robinia pseudacacia with admixture of Quercus petraea and Quercus robur. This shelterbelt and adjoining cultivated field are located on grey-brown podzolic soil. The aim of this study is to present information on the changes of nitrate reductase activity in soil with admixture urea (organic form of nitrogen) in two different concentrations 0,25% N and 0,5% N. Our results have shown that this process

    NASA Astrophysics Data System (ADS)

    Parkash, B.; Rathor, S.; Pati, P.

    2012-04-01

    Our studies in the Gangetic plains and review of the work on the Himalaya suggest that both theses features are marked by abrupt changes across the Rapti River, flowing N-S in the plains and region N to it, instead of a gradual change from E to W as postulated earlier. The Eastern Nepal Himalaya N to the Middle Gangetic Plains (east of the Rapti River) is characterized by a high rate of convergence, which sustains the highest peaks in the world, including the Mount Everest. These lofty peaks cause significant crustal loading leading to high rate of subsidence in the foreland basin and also shed large sediment load, carried by the rivers to the plains to form megafans (e.g. Kosi and Gandak megafans). In the NW and the W Nepal Himalaya, rates of crustal shortening due to movements along the Himalayan Frontal Trust (HFT) are low, which are able to support lower heights of the Himalayan ranges (< 7000 m). These ranges shed small amounts of sediments, which are carried by streams to the plains. The adjoining foreland basin, the Upper Gangetic plain lying W to the Rapti River, is subsiding at a low rate, all major rivers are incised, and form large uplands. Moderately to strongly developed soils occur on the upland plains. These situations indicate the prevalence of separate steady states between the Upper- and Middle Gangetic plains and adjoining Himalaya.

  1. Introductory lecture: nanoplasmonics.

    PubMed

    Brongersma, Mark L

    2015-01-01

    Nanoplasmonics or nanoscale metal-based optics is a field of science and technology with a tremendously rich and colourful history. Starting with the early works of Michael Faraday on gold nanocolloids and optically-thin gold leaf, researchers have been fascinated by the unusual optical properties displayed by metallic nanostructures. We now can enjoy selecting from over 10 000 publications every year on the topic of plasmonics and the number of publications has been doubling about every three years since 1990. This impressive productivity can be attributed to the significant growth of the scientific community as plasmonics has spread into a myriad of new directions. With 2015 being the International Year of Light, it seems like a perfect moment to review some of the most notable accomplishments in plasmonics to date and to project where the field may be moving next. After discussing some of the major historical developments in the field, this article will analyse how the most successful plasmonics applications are capitalizing on five key strengths of metallic nanostructures. This Introductory Lecture will conclude with a brief look into the future. PMID:25968246

    Osteomyelitis of clavicle is rare in neonates. Acute osteomyelitis of clavicle accounts for less than 3% of all osteomyelitis cases. It may occur due to contiguous spread, due to hematogenous spread, or secondary to subclavian catheterization. Chronic osteomyelitis may occur as a complication of residual adjoining abscess due to methicillin resistant staphylococcus aureus (MRSA) sepsis. We report a newborn female with right shoulder abscess that developed chronic clavicular osteomyelitis in follow-up period after drainage. She required multiple drainage procedures and was later successfully managed with bone curettage and debridement. We report this case to highlight that a MRSA abscess may recur due to residual infection from a chronic osteomyelitis sinus. It may be misdiagnosed as hypergranulation tissue of nonhealing wound leading to inappropriate delay in treatment. High index of suspicion, aggressive initial management, and regular follow-up are imperative to prevent this morbid complication. PMID:27051549

  3. The Role of Introductory Geosciences in Students' Quantitative Literacy

    Quantitative literacy is more than mathematics; it is about reasoning with data. Colleges and universities have begun to recognize the distinction between mathematics and quantitative literacy, modifying curricula to reflect the need for numerate citizens. Although students may view geology as 'rocks for jocks', the geosciences are truthfully rife with data, making introductory geoscience topics excellent context for developing the quantitative literacy of students with diverse backgrounds. In addition, many news items that deal with quantitative skills, such as the global warming phenomenon, have their basis in the Earth sciences and can serve as timely examples of the importance of quantitative literacy for all students in introductory geology classrooms. Participants at a workshop held in 2006, 'Infusing Quantitative Literacy into Introductory Geoscience Courses,' discussed and explored the challenges and opportunities associated with the inclusion of quantitative material and brainstormed about effective practices for imparting quantitative literacy to students with diverse backgrounds. The tangible results of this workshop add to the growing collection of quantitative materials available through the DLESE- and NSF-supported Teaching Quantitative Skills in the Geosciences website, housed at SERC. There, faculty can find a collection of pages devoted to the successful incorporation of quantitative literacy in introductory geoscience. The resources on the website are designed to help faculty to increase their comfort with presenting quantitative ideas to students with diverse mathematical abilities. A methods section on "Teaching Quantitative Literacy" (http://serc.carleton.edu/quantskills/methods/quantlit/index.html) focuses on connecting quantitative concepts with geoscience context and provides tips, trouble-shooting advice and examples of quantitative activities. The goal in this section is to provide faculty with material that can be readily incorporated

  18. Spatial and vertical variability of different types of tropical precipitating systems over India and adjoining oceans

    NASA Astrophysics Data System (ADS)

    Narayana Rao, T.; Saikranthi, K.

    2012-07-01

    The classification of precipitation into different rain regimes is useful for a variety of meteorological applications, from fundamental understanding of cloud physics, areal quantification of rainfall using scanning radars (both space-borne and ground-based) and microwave retrieval of rainfall. Also the latent heat profiles of different precipitating systems are distinct, which impact the atmospheric circulation differently. Earlier studies focused their attention on quantification of the surface rainfall and its variability on different temporal scales (intraseasonal, interannual, decadal, etc.). Further, earlier studies on rainfall were not able to study the vertical structure of precipitation, because they are mostly based on rain gauge measurements. The present study, therefore, aims to devise a classification scheme by grouping TRMM PR derived rain types into shallow (stratus and convection) and deep (stratiform, convection and transition) precipitating systems and provide a quantitative description of these systems by effectively utilizing 13 years of TRMM measurements, European Centre for Medium-Range Weather Forecasts (ECMWF)-Interim reanalysis products and radiosonde measurements at 33 stations in India. In particular, this study addresses the following important questions. Which type of rainfall (stratiform, convective, and warm rain) prevails most over different parts of India? How much each type of precipitation contributes to the total rainfall? The present study focuses not on the absolute amounts of precipitation by each type of system, rather on studying the relative contributions of different types of systems to the total precipitation and their occurrence over India and adjoining oceans. We also discuss the problems associated with the utilization of climatological surface data for estimating the freezing level height, which is required for identifying warm rain and also for stratiform rain (for bright band detection). TRMM PR underestimates (in

    We examine the tsunami potential from sources located in the South China Sea and its adjoining basins, the Sulu and Sulawezi Seas, by running simulations using the MOST code for a number of scenarios of possible earthquakes at the various local subduction zones. In the Sulawezi Sea, we consider the events of 1918 at the Mindanao subduction zone, and 1996 at the Northern end of the Makassar Strait. In the Sulu Sea, we consider a scenario inspired by the 1948 Panay earthquake (because of the fractured nature of the plate system in those areas, it is not feasible to consider much larger earthquakes). In all three cases, we find that the tsunami is contained within the relevant marginal sea and does not penetrate significantly the greater South China Basin, but could cause significant damage to the Eastern coast of Borneo. Farther North, we consider as worst case scenarios events reaching 10**29 dyn*cm with rupture lengths of 400 km, both off Luzon Island and, under a slightly different geometry, off the Luzon Straits separating the Philippines and Taiwan. Such scenarios carry very significant hazard to all coastlines bordering the South China Sea, including Indochina and Borneo. We will also present models of landslide-generated tsunamis, inspired from the event of 14 February 1934 off the Luzon Strait, and the presumably Holocene Brunei mega-slide.

    The tsunami potential from sources located in the South China Sea and its adjoining basins, Sulu and Sulawesi Seas, is examined. Tsunami numerical modeling was performed using the MOST code [Titov and Synolakis, 1998] for a number of possible earthquake scenarios at the various local subduction zones. For the Sulawesi Sea, we consider the events of 1918 at the Mindanao subduction zone, and the 1996 at the Northern end of the Makassar Strait. For the Sulu Sea, we consider a scenario inspired by the 1948 Panay earthquake (because of the fractured nature of the plate system in those areas, it is not feasible to consider much larger earthquakes). Tsunami simulations of these events show that the tsunami is contained within the relevant marginal seas and does not penetrate significantly the greater South China Basin. However, tsunami hazard that could cause significant damage was found for the Eastern coast of Borneo. Farther North, we consider as worst case scenarios events reaching 10**29 dyn*cm with rupture lengths of 400 km, both off Luzon Island and, under a slightly different geometry, off the Luzon Straits separating the Philippines and Taiwan. These scenarios show very significant hazard to all coastlines bordering the South China Sea, including Indochina and Borneo. Finally, two landslide-generated tsunami scenarios are presented, inspired from the event of 14 February 1934 off the Luzon Strait, and the presumably Holocene Brunei mega-slide.

  1. Tectonic and deposition model of late Precambrian-Cambrian Arabian and adjoining plates

    1989-09-01

    During the late Precambrian, the terranes of the Arabian and adjoining plates were fused along the northeastern flank of the African plate in Gondwanaland. This phase, which ended approximately 640 to 620 Ma, was followed by continental failure (620 to 580 Ma) and intracontinental extension (600 to approximately 550 Ma). During the Infracambrian extensional phase, a triple junction may have evolved near the Sinai Peninsula and may have consisted of the (1) Jordan Valley and Dead Sea rift branch, (2) Sinai and North Egypt rift branch, and (3) the Najd wrench-rift branch. The Najd, Hawasina, and Zagros fault systems may have been transverse faults that accompanied rifting in the Arabian Gulf and Zagros Mountains, southern Oman, Pakistan, and Kerman in central Iran. While the area was extending and subsiding, the Tethys Ocean flooded the eastern side of the Arabian plate and Iran and deposited calcareous clastics, carbonates, and evaporites (including the Hormuz and Ara halites). This transgression extended into the western part of the Arabian plate via the Najd rift system. The termination of the extensional phase during the late Early Cambrian was accompanied by a major regression and terrestrial conditions on the Arabian Peninsula. However, by the Early Ordovician, as sea level peaked to a highstand, the Arabian plate was blanketed with marginal marine sediments. 11 figs., 2 tabs.

  2. Lowstand carbonate reservoirs: Upper Pennsylvanian sea level changes and reservoir development adjoining Horseshoe Atoll

    The majority of carbonate reservoirs comprising the Horseshoe Atoll were deposited as reefs and skeletal sand banks during sea level highstands of glacio-eustatic origin, during Canyon (Missourian) and Cisco (Virgilian) deposition. During lowstands, previously deposited carbonate rocks were exposed subaerially to intense meteoric dissolution and karstification creating the pore systems typical of most Horseshoe Atoll fields. Detailed biostratigraphic and sedimentologic studies and recent discoveries adjoining the Horseshoe Atoll have documented the deposition of in-situ and associated intraclastic limestone reservoirs deposited in former slope and basin locations concomittant with periods of sea level lowstand. The authors data suggest that the deposition of such reservoirs occurred throughout the Late Pennsylvanian and accompanied sea level drops of as great as 200 m. To date, productive lowstand reservoirs have been identified in rocks of the middle lower, upper lower, and upper middle Missourian, and the lower lower Virgilian. These deposits are represented by porous reefs, skeletal sandstones, and porous-to-tight intraclastic limestones previously referred to as satellite or pinnacle reefs. These deposits, subsequently onlapped and buried by deepwater shales, comprise potentially prolific stratigraphic-trap reservoirs in basinal areas seaward of the Horseshoe Atoll.

  3. Tectonic and depositional model of the Arabian and adjoining plates during the Silurian-Devonian

    1991-01-01

    During the Late Ordovician and Early Silurian, the western part of the Arabian Peninsula was covered by polar glaciers that advanced from the south pole in African Gondwana. During this period, nondeposition, erosion, or marginal marine conditions prevailed in eastern and northern Arabia. When the glaciers melted in the Early Silurian, sea level rose sharply and the paleo-Tethys Ocean transgressed the Arabian and adjoining plates depositing a thick, organic-rich shale directly over the glaciogenic and periglacial rocks and related unconformities. The post-glacial sequence coarsens upward reflecting the passage of a coastline prograding northward from African and Arabian Gondwana to northern Arabia. A sea level drop in the Late Silurian placed the study area in a terrestrial environment; however, as sea level recovered in the Early Devonian, a carbonate sequence blanketed most of the area. The transgression, however, was interrupted by regional uplift and local orogenic movements in the Middle and Late Devonian. These movements constitute the onset of Hercynian tectonism, which resulted in erosion of the older sequences, depositional hiatuses, and regional facies changes.

  4. Geology and geophysics of south-central Zavala and adjoining parts of Dimmit Counties, Texas

    Gravity, magnetic, and seismic surveys combined with subsurface geologic investigations resulted in very intriguing interpretations of an area east of Crystal City, Texas. The study area includes the south-central part of Zavala County east of the Nueces River and the adjoining parts of Dimmit County to the south. The Elaine field is included in the study area. Gravity and magnetic residuals were calculated using the least-squares method, and the magnetic surveys revealed several serpentine plugs, which are confirmed by seismic interpretations. Although no geophysics work was done, subsurface study shows that Elaine field is the largest of these plugs. Seismic studies also show that the Austin Chalk, on whose surface the lava was extruded, is highly fractured and faulted. The Austin under the Elaine field is the lowest structural feature in the area. The Anacacho was deposited on the lava surface, and in the Elaine area it has a reeflike appearance. Isopachs of younger sediments show that they are draped and differentially compacted over the plugs, and that the Elaine plug affects sediments as young as Escondido. Production in the area is mainly from the San Miguel, but significant amounts of hydrocarbons have also been produced from Eagle Ford, Austin, Anacacho, and Olmos reservoirs.

  5. Improved segmentation of occluded and adjoining vehicles in traffic surveillance videos

    Occlusion in image processing refers to concealment of any part of the object or the whole object from view of an observer. Real time videos captured by static cameras on roads often encounter overlapping and hence, occlusion of vehicles. Occlusion in traffic surveillance videos usually occurs when an object which is being tracked is hidden by another object. This makes it difficult for the object detection algorithms to distinguish all the vehicles efficiently. Also morphological operations tend to join the close proximity vehicles resulting in formation of a single bounding box around more than one vehicle. Such problems lead to errors in further video processing, like counting of vehicles in a video. The proposed system brings forward efficient moving object detection and tracking approach to reduce such errors. The paper uses successive frame subtraction technique for detection of moving objects. Further, this paper implements the watershed algorithm to segment the overlapped and adjoining vehicles. The segmentation results have been improved by the use of noise and morphological operations.

    The investigations were carried out in Dezydery Chlapowski Agroecological Landscape Park in Turew (40 km South-West of Poznań, West Polish Lowlands, 16° 45 E and 52° 01 N). Intensively agriculture is observed in this region. Characteristic features of this landscape are shelterbelts created in the XIX century by the general Dezydery Chlapowski. Soil samples were taken from Robinia pseudoacacia shelterbelt and from adjoining cultivated field. This is 200 - years old shelterbelt consists mainly of Robinia pseudacacia and small admixture of Quercus robur and Quercus petraea. It is 2 kilometers length and 36 meters width. Shelterbelts and adjoining cultivated fields were introduced on Hapludalfs soils (according to FAO classification). The aim of this study was to evaluate the effect of moisture and nitrogen concentrations on the changes of nitrate reductase activity in soil under shelterbelt and in adjoining cultivated field. The experiments were carried out in two different moisture content. The first was field-moist and the second was 15% moisture content. In this study three different contents of nitrogen in the form of urea (organic form of nitrogen) were investigated: field concentration, after addition of 0.25% and 0.5% of nitrogen. Activity of nitrate reductase changes in different interval of time were measured. Rate constant of reactions was calculated for the changes of nitrate reductase activity. Our results have shown that this process runs according to the equation rate of first-order kinetic reaction model. The first-order reaction rate constants increases with the changes of moisture content from field-moist to 15% in soil under shelterbelt. In soil under adjoining cultivated field raise of the moisture content from field-moist to 15% causes an increase of the first-order reaction rate constants higher than in soil under shelterbelt. The processes of the changes of nitrate reductase activity 15% moisture content of the soil under shelterbelt and in

  8. Tsunami Simulations for Regional Sources in the South China and Adjoining Seas

    2011-06-01

    We present 14 scenarios of potential tsunamis in the South China Sea and its adjoining basins, the Sulu and Sulawezi Seas. The sources consist of earthquake dislocations inspired by the the study of historical events, either recorded (since 1900) or described in historical documents going back to 1604. We consider worst-case scenarios, where the size of the earthquake is not limited by the largest known event, but merely by the dimension of the basin over which a coherent fault may propagate. While such scenarios are arguably improbable, they may not be impossible, and as such must be examined. For each scenario, we present a simulation of the tsunami's propagation in the marine basin, exclusive of its interaction with the coastline. Our results show that the South China, Sulu and Sulawezi Seas make up three largely independent basins where tsunamis generated in one basin do not leak into another. Similarly, the Sunda arc provides an efficient barrier to tsunamis originating in the Indian Ocean. Furthermore, the shallow continental shelves in the Java Sea, the Gulf of Thailand and the western part of the South China Sea significantly dampen the amplitude of the waves. The eastern shores of the Malay Peninsula are threatened only by the greatest—and most improbable—of our sources, a mega-earthquake rupturing all of the Luzon Trench. We also consider two models of underwater landslides (which can be triggered by smaller events, even in an intraplate setting). These sources, for which there is both historical and geological evidence, could pose a significant threat to all shorelines in the region, including the Malay Peninsula.

Modern physics, which in introductory textbooks "appears in one or more extra chapters at the end of the book, … is a divertimento that we might get to if time permits."

    Northeast India and adjoining regions (20°-32° N and 87°-100° E) are highly vulnerable to earthquake hazard in the Indian sub-continent, which fall under seismic zones V, IV and III in the seismic zoning map of India with magnitudes M exceeding 8, 7 and 6, respectively. It has experienced two devastating earthquakes, namely, the Shillong Plateau earthquake of June 12, 1897 ( M w 8.1) and the Assam earthquake of August 15, 1950 ( M w 8.5) that caused huge loss of lives and property in the Indian sub-continent. In the present study, the probabilities of the occurrences of earthquakes with magnitude M ≥ 7.0 during a specified interval of time has been estimated on the basis of three probabilistic models, namely, Weibull, Gamma and Lognormal, with the help of the earthquake catalogue spanning the period 1846 to 1995. The method of maximum likelihood has been used to estimate the earthquake hazard parameters. The logarithmic probability of likelihood function (ln L) is estimated and used to compare the suitability of models and it was found that the Gamma model fits best with the actual data. The sample mean interval of occurrence of such earthquakes is estimated as 7.82 years in the northeast India region and the expected mean values for Weibull, Gamma and Lognormal distributions are estimated as 7.837, 7.820 and 8.269 years, respectively. The estimated cumulative probability for an earthquake M ≥ 7.0 reaches 0.8 after about 15-16 (2010-2011) years and 0.9 after about 18-20 (2013-2015) years from the occurrence of the last earthquake (1995) in the region. The estimated conditional probability also reaches 0.8 to 0.9 after about 13-17 (2008-2012) years in the considered region for an earthquake M ≥ 7.0 when the elapsed time is zero years. However, the conditional probability reaches 0.8 to 0.9 after about 9-13 (2018-2022) years for earthquake M ≥ 7.0 when the elapsed time is 14 years (i.e. 2009).

    NASA Technical Reports Server (NTRS)

    1977-01-01

    A market survey was conducted regarding the commercialization potential and key market factors relevant to a tactile paging system for deaf-blind people. The purpose of the tactile paging system is to communicate to the deaf-blind people in an institutional environment. The system consists of a main console and individual satellite wrist units. The console emits three signals by telemetry to the wrist com (receiving unit) which will measure approximately 2 x 4 x 3/4 inches and will be fastened to the wrist by a strap. The three vibration signals are fire alarm, time period indication, and a third signal which will alert the wearer of the wrist com to the fact that the pin on the top of the wrist is emitting a morse coded message. The Morse code message can be felt and recognized with the finger.

    We introduce Problem Roulette (PR), a web-based study service at the University of Michigan that offers random-within-topic access to a large library of past exam problems in introductory physics courses. Built on public-private cloud infrastructure, PR served nearly 1000 students during Fall 2012 term, delivering more than 60,000 problem pages. The service complements that of commercial publishing houses by offering problems authored by local professors and by explicitly aligning topics with exam content. We describe the service architecture, including reporting and analytical capabilities, and present an initial evaluation of the impact of its use. Among roughly 500 students studying electromagnetism, we find that the 229 students who worked fifty or more problems over the term outperformed their complement by 0.40 grade points (on a 4.0 scale). This improvement partly reflects a selection bias that academically stronger students used the service more frequently. Adjusting for this selection bias, we find a grade point improvement of 0.22, significantly above the random noise level of 0.04. The simple message to students is that working five or more additional problems per week can lead to a quarter-letter grade improvement in introductory physics. Student comments emphasize the importance of randomness in helping them to synthesize concepts. The PR source code is publicly available.

The Supreme Court of Wyoming held that the state Department of Health was not authorized to inquire about the sincerity of a mother's religious beliefs when determining whether her daughter was exempt from a public school immunization requirement. Susan LePage submitted a request to the Department of Health seeking to exempt her daughter from receiving the hepatitis B vaccination. The Department of Health inquired into the sincerity of LePage's religious beliefs against vaccination and determined that her objections were of a personal or philosophical nature and not on religious grounds. The Department of Health denied LePage's request. The Supreme Court of Wyoming held that state law requires the Department of Health to grant an exemption upon the submission of a written objection and does not allow the Department of Health to make an inquiry into the sincerity of the requestor's religious beliefs. The court balanced a valid state interest in protecting schoolchildren from disease with the relatively low number of requests for exemption and its confidence in parents to make decisions in the best interest of their children's physical and spiritual health. Since there was no justification within the statute to allow a religious inquiry, the court held that the Department of Health had exceeded its authority with LePage. Furthermore, state law did not require a religious waiver to exempt a child from this particular vaccine. The lower court's holding was reversed. PMID:16479706

  19. Observing Projects in Introductory Astronomy

    NASA Astrophysics Data System (ADS)

    Taylor, M. Suzanne

    2016-01-01

    Introductory astronomy classes without laboratory components face a unique challenge of how to expose students to the process of science in the framework of a lecture course. As a solution to this problem small group observing projects are incorporated into a 40 student introductory astronomy class composed primarily of non-science majors. Students may choose from 8 observing projects such as graphing the motion of the moon or a planet, measuring daily and seasonal motions of stars, and determining the rotation rate of the Sun from sunspots. Each group completes two projects, requiring the students to spend several hours outside of class making astronomical observations. Clear instructions and a check-list style observing log help students with minimal observing experience to take accurate data without direct instructor assistance. Students report their findings in a lab report-style paper, as well as in a formal oral or poster presentation. The projects serve a double purpose of allowing students to directly experience concepts covered in class as well as providing students with experience collecting, analyzing, and presenting astronomical data.

  20. Worldviews of Introductory Astronomy Students

    Green, Chrystin; Wallace, C. S.; Brissenden, G.; Prather, E. E.; Collaboration of Astronomy Teaching Scholars (CATS)

    2014-01-01

    As a part of a larger project to study introductory astronomy students’ worldviews and beliefs about the role of science in society, we examined students’ responses to a subset of questions designed to probe students’ worldviews and how they change after taking a general education, introductory astronomy course (Astro 101). Specifically, we looked at about 400 students’ choices for the top ten scientific discoveries in the past 150 years. We collected students’ rankings twice: Once at the start of their Astro 101 class and once at the end. We created a rubric that we used to categorize the responses and we established the inter-rater reliability of the rubric. Our results show that students preferentially answered with topics related to technology and health and medicine. The data also show that there was an increase, pre- to post-instruction, in the number of responses in the technology and health and medicine categories. We also saw a decrease in the number of responses in the science category. These results imply that an aspect of the course specifically implemented to broaden student’s views on science in relation to society was successful.

    Dash, Sushil K.; Mishra, Saroj K.; Pattnayak, Kanhu C.; Mamgain, Ashu; Mariotti, Laura; Coppola, Erika; Giorgi, Filippo; Giuliani, Graziano

    2015-11-01

    In this study, we present the projected seasonal mean summer monsoon over India and adjoining regions for the twenty-first century under the representative concentration pathway (RCP) 4.5 and RCP 8.5 scenarios using the regional model RegCM4 driven by the global model GFDL-ESM2M. RegCM4 is integrated from 1970 to 2099 at 50 km horizontal resolution over the South Asia CORDEX domain. The simulated mean summer monsoon circulation and associated rainfall by RegCM4 are validated against observations in the reference period 1975 to 2004 based on the Global Precipitation Climatology Project (GPCP) and India Meteorological Department (IMD) data sets. Regional model results are also compared with those of the global model GFDL which forces the RegCM4, showing that the regional model in particular improves the simulation of precipitation trends during the reference period. Future projections are categorized as near future (2010-2039), mid future (2040-2069), and far future (2070-2099). Comparison of projected seasonal (June-September) mean rainfall from the different time slices indicate a gradual increase in the intensity of changes over some of the regions under both the RCP4.5 and RCP8.5 scenarios. RegCM4 projected rainfall decreases over most of the Indian land mass and the equatorial and northern Indian Ocean, while it increases over the Arabian Sea, northern Bay of Bengal, and the Himalayas. Results show that the monsoon circulation may become weaker in the future associated with a decrease in rainfall over Indian land points. The RegCM4 projected decrease in June, July, August, September (JJAS) rainfall under the RCP8.5 scenario over the central, eastern, and peninsular India by the end of the century is in the range of 25-40 % of their mean reference period values; it is significant at the 95 % confidence level and it is broadly in line with patterns of observed change in recent decades. Surface evaporation is projected to increase over the Indian Ocean, thereby

  4. Using Science Fiction Movies in Introductory Physics

    NASA Astrophysics Data System (ADS)

    Dark, Marta L.

    2005-10-01

    This paper discusses the use of science fiction movies in introductory physics courses at Spelman College. There are several reasons to use these movies in the classroom environment. Movies are a visual learning aid. Introductory physics students show a strong interest in participating in movie-related activities compared to standard group problem-solving sessions. Finally, these activities encourage creative thinking and can be used to develop writing skills. The students involved with these movie-based activities have included biology and pre-medical majors taking general physics. In the introductory level courses, physics, chemistry, and engineering majors worked on movie-based activities.

  5. Learning from the Starry Message: Using Galileo's Sidereus Nuncius in Introductory Astronomy Classes

    NASA Astrophysics Data System (ADS)

    Wiesner, Matthew P.

    2015-03-01

    Every introductory astronomy class encounters Galileo during the course as the first man to systematically study the sky with a telescope. Every Astronomy 101 student meets Galileo as one of the major catalysts behind the shift from the Ptolemaic to the Copernican system and as one of the great minds behind the scientific method. But most of the time Galileo is just an inset on page 17 with one of the canonical portraits, appearing in students' lists of six early astronomers that need to be memorized for the first exam. I have tried to find ways to overcome such shallow educational experiences in introductory astronomy. In order to bring students to a real encounter with Galileo, I have assigned reading of an excerpt from Galileo's Sidereus Nuncius, "The Starry Message," followed by an inclass discussion of the text.

  9. Lithospheric structure of southern Indian shield and adjoining oceans: integrated modelling of topography, gravity, geoid and heat flow data

    NASA Astrophysics Data System (ADS)

    Kumar, Niraj; Zeyen, H.; Singh, A. P.; Singh, B.

    2013-07-01

    For the present 2-D lithospheric density modelling, we selected three geotransects of more than 1000 km in length each crossing the southern Indian shield, south of 16°N, in N-S and E-W directions. The model is based on the assumption of local isostatic equilibrium and is constrained by the topography, gravity and geoid anomalies, by geothermal data, and where available by seismic data. Our integrated modelling approach reveals a crustal configuration with the Moho depth varying from ˜40 km beneath the Dharwar Craton, and ˜39 km beneath the Southern Granulite Terrane to about 15-20 km beneath the adjoining oceans. The lithospheric thickness varies significantly along the three profiles from ˜70-100 km under the adjoining oceans to ˜130-135 km under the southern block of Southern Granulite Terrane including Sri Lanka and increasing gradually to ˜165-180 km beneath the northern block of Southern Granulite Terrane and the Dharwar Craton. This step-like lithosphere-asthenosphere boundary (LAB) structure indicates a normal lithospheric thickness beneath the adjoining oceans, the northern block of Southern Granulite Terrane and the Dharwar Craton. The thin lithosphere below the southern block of Southern Granulite Terrane including Sri Lanka is, however, atypical considering its age. Our results suggest that the southern Indian shield as a whole cannot be supported isostatically only by thickened crust; a thin and hot lithosphere beneath the southern block of Southern Granulite Terrane including Sri Lanka is required to explain the high topography, gravity, geoid and crustal temperatures. The widespread thermal perturbation during Pan-African (550 Ma) metamorphism and the breakup of Gondwana during late Cretaceous are proposed as twin cause mechanism for the stretching and/or convective removal of the lower part of lithospheric mantle and its replacement by hotter and lighter asthenosphere in the southern block of Southern Granulite Terrane including Sri Lanka

  10. Plasma medicine: an introductory review

    NASA Astrophysics Data System (ADS)

    Kong, M. G.; Kroesen, G.; Morfill, G.; Nosenko, T.; Shimizu, T.; van Dijk, J.; Zimmermann, J. L.

    2009-11-01

    This introductory review on plasma health care is intended to provide the interested reader with a summary of the current status of this emerging field, its scope, and its broad interdisciplinary approach, ranging from plasma physics, chemistry and technology, to microbiology, biochemistry, biophysics, medicine and hygiene. Apart from the basic plasma processes and the restrictions and requirements set by international health standards, the review focuses on plasma interaction with prokaryotic cells (bacteria), eukaryotic cells (mammalian cells), cell membranes, DNA etc. In so doing, some of the unfamiliar terminology—an unavoidable by-product of interdisciplinary research—is covered and explained. Plasma health care may provide a fast and efficient new path for effective hospital (and other public buildings) hygiene—helping to prevent and contain diseases that are continuously gaining ground as resistance of pathogens to antibiotics grows. The delivery of medically active 'substances' at the molecular or ionic level is another exciting topic of research through effects on cell walls (permeabilization), cell excitation (paracrine action) and the introduction of reactive species into cell cytoplasm. Electric fields, charging of surfaces, current flows etc can also affect tissue in a controlled way. The field is young and hopes are high. It is fitting to cover the beginnings in New Journal of Physics, since it is the physics (and non-equilibrium chemistry) of room temperature atmospheric pressure plasmas that have made this development of plasma health care possible.

  11. Cervical cytology screening in Calcutta and adjoining areas with special reference to carcinoma of the uterine cervix.

    1990-01-01

    A total of 1232 female subjects including 100 prostitutes from Calcutta and adjoining areas in the age group of 21-70 years were screened for cervical pathology according to the method of Papanicolaou. Of 1232 examined, 815 were found to have smears with normal cellular cytology (66.15%). The others were grouped into dysplasia (18.4%) and inflammatory (15.4%) according to the cytomorphological characteristics of the exfoliated cells. The findings though revealed more cases of cervical dysplasia in women with early marriage, early childbirth, high parity and multiple sexual partners, it failed to support the smegma theory of cervical carcinoma. This study also showed a number of inflammatory cervical smears in women coming from low socio-economic group. PMID:2102897

  12. Mitigating DoS Attacks on the Paging Channel by Efficient Encoding in Page Messages

    NASA Astrophysics Data System (ADS)

    Cai, Liang; Maganis, Gabriel; Zang, Hui; Chen, Hao

    Paging is an important mechanism for network bandwidth efficiency and mobile terminal battery life. It has been widely adopted by mobile networks, such as cellular networks, WiMax, and Mobile IP. Due to certain mechanisms for achieving paging efficiency and the convergence of wireless voice and data networks, the paging channel is vulnerable to inexpensive DoS attacks. To mitigate these attacks, we propose to leverage the knowledge of the user population size, the slotted nature of the paging operation, and the quick paging mechanism to reduce the length of terminal identifiers. In the case of a CDMA2000 system, we can reduce each identifier from 34 bits down to 7 bits, effectively doubling the paging channel capacity. Moreover, our scheme incurs no paging latency, missed pages, or false pages. Using a simulator and data collected from a commercial cellular network, we demonstrate that our scheme doubles the cost for DoS attackers.

  13. Social Bookmarking Induced Active Page Ranking

    NASA Astrophysics Data System (ADS)

    Takahashi, Tsubasa; Kitagawa, Hiroyuki; Watanabe, Keita

    Social bookmarking services have recently made it possible for us to register and share our own bookmarks on the web and are attracting attention. The services let us get structured data: (URL, Username, Timestamp, Tag Set). And these data represent user interest in web pages. The number of bookmarks is a barometer of web page value. Some web pages have many bookmarks, but most of those bookmarks may have been posted far in the past. Therefore, even if a web page has many bookmarks, their value is not guaranteed. If most of the bookmarks are very old, the page may be obsolete. In this paper, by focusing on the timestamp sequence of social bookmarkings on web pages, we model their activation levels representing current values. Further, we improve our previously proposed ranking method for web search by introducing the activation level concept. Finally, through experiments, we show effectiveness of the proposed ranking method.

  14. Realistic page-turning of electronic books

    NASA Astrophysics Data System (ADS)

    Fan, Chaoran; Li, Haisheng; Bai, Yannan

    2014-01-01

    The booming electronic books (e-books), as an extension to the paper book, are popular with readers. Recently, many efforts are put into the realistic page-turning simulation o f e-book to improve its reading experience. This paper presents a new 3D page-turning simulation approach, which employs piecewise time-dependent cylindrical surfaces to describe the turning page and constructs smooth transition method between time-dependent cylinders. The page-turning animation is produced by sequentially mapping the turning page into the cylinders with different radii and positions. Compared to the previous approaches, our method is able to imitate various effects efficiently and obtains more natural animation of turning page.

  4. Teaching Electrostatics and Entropy in Introductory Physics

    NASA Astrophysics Data System (ADS)

    Reeves, Mark

    Entropy changes underlie the physics that dominates biological interactions. Indeed, introductory biology courses often begin with an exploration of the qualities of water that are important to living systems. However, one idea that is not explicitly addressed in most introductory physics or biology courses is important contribution of the entropy in driving fundamental biological processes towards equilibrium. I will present material developed to teach electrostatic screening in solutions and the function of nerve cells where entropic effects act to counterbalance electrostatic attraction. These ideas are taught in an introductory, calculus-based physics course to biomedical engineers using SCALEUP pedagogy. Results of student mastering of complex problems that cross disciplinary boundaries between biology and physics, as well as the challenges that they face in learning this material will be presented.

  5. Innovative Technology for Teaching Introductory Astronomy

    NASA Astrophysics Data System (ADS)

    Guidry, Mike

    The application of state-of-the-art technology (primarily Java and Flash MX Actionscript on the client side and Java PHP PERL XML and SQL databasing on the server side) to the teaching of introductory astronomy will be discussed. A completely online syllabus in introductory astronomy built around more than 350 interactive animations called ""Online Journey through Astronomy"" and a new set of 20 online virtual laboratories in astronomy that we are currently developing will be used as illustration. In addition to demonstration of the technology our experience using these technologies to teach introductory astronomy to thousands of students in settings ranging from traditional classrooms to full distance learning will be summarized. Recent experiments using Java and vector graphics programming of handheld devices (Personal Digital Assistants and cell phones) with wireless wide-area connectivity for applications in astronomy education will also be described.

  8. Effects of Interactive Applets on Student Understanding and Explanation of Introductory Weather Concepts

    NASA Astrophysics Data System (ADS)

    Ackerman, S. A.; Yaros, R. A.; Whittaker, T.

    2004-12-01

    Use of the Internet's virtually unlimited resources continues to increase in introductory college courses. The "Web" can offer students with: lecture notes, graphics, study guides (such as flash cards), self-administered quizzes, and interactive applets that animate complex concepts and processes. In the lecture-based course "Weather and Climate," consisting of approximately 400 non-science majors, interactive applets were developed to demonstrate introductory meteorological concepts. Results from the course's formative evaluation suggest utility of the supplemental online resources in student learning. In this study, we pursue three goals to empirically measure the effects of the animated meteorological applets on the learning. First, we measure if an interactive applet increases comprehension of scientific explanations by students with no previous expert knowledge. Second, we measure whether the applet enhance their understanding of "cause-and-effect" processes. Third, we investigate whether an applet facilitates a student's application of concepts and processes to problem-solving. Methodologically, approximately 400 students are randomly assigned to one of two conditions. One group is exposed to only text and graphics on a Web page that explains the concept of relative humidity. The second group of students is exposed to the same Web page of text and graphics, but also to an animated applet with which students can interact. To assess learning gains, students' responses to questions about these presented concepts are compared. Recall and free recall of content is measured using questions that range from text-based definitions (multiple choice) to problem-solving (short answer).

  9. Computer Based Collaborative Problem Solving for Introductory Courses in Physics

    NASA Astrophysics Data System (ADS)

    Ilie, Carolina; Lee, Kevin

    2010-03-01

    We discuss collaborative problem solving computer-based recitation style. The course is designed by Lee [1], and the idea was proposed before by Christian, Belloni and Titus [2,3]. The students find the problems on a web-page containing simulations (physlets) and they write the solutions on an accompanying worksheet after discussing it with a classmate. Physlets have the advantage of being much more like real-world problems than textbook problems. We also compare two protocols for web-based instruction using simulations in an introductory physics class [1]. The inquiry protocol allowed students to control input parameters while the worked example protocol did not. We will discuss which of the two methods is more efficient in relation to Scientific Discovery Learning and Cognitive Load Theory. 1. Lee, Kevin M., Nicoll, Gayle and Brooks, Dave W.

  7. Lithium/pilocarpine status epilepticus-induced neuropathology of piriform cortex and adjoining structures in rats is age-dependent.

    PubMed

    Druga, R; Kubová, H; Suchomelová, L; Haugvicová, R

    2003-01-01

    Distribution of LiCl/pilocarpine status epilepticus-induced neuronal damage was studied in the piriform cortex and in adjoining structures in 12-day-old, 25-day-old and adult rats. No distinct structural and neuronal alterations were detected in the basal telencephalon in 12-day-old rats surviving status epilepticus (SE) for one week or two months. In 25-day-old rats a decrease in Nissl staining was evident. There was also cell loss and gliosis in the caudal 2/3 of the piriform cortex, in the superficial amygdaloid nuclei, in the dorsal and ventral endopiriform nucleus and in the rostrolateral part of the entorhinal cortical area. In adult animals, the topography of neuropathological changes in the basal telencephalon was comparable to those in 25-day-old rats. The damage in the caudal 2/3 or caudal half of the piriform cortex in adult rats with survival times one week or two months was characterized by a marked loss of neurons and striking glial infiltration. The thickness of the piriform cortex and superficial amygdaloid nuclei was significantly reduced. In 25-day-old and in adult animals the sublayer IIb and layer III of the piriform cortex was more affected, while sublayer IIa was less damaged. Parvalbumin (PV) immunocytochemistry revealed a significant decrease in the number of PV-immunoreactive neurons in the rostral piriform cortex and in the dorsal claustrum in animals surviving for two months.

  8. Universal emergence of PageRank

    NASA Astrophysics Data System (ADS)

    Frahm, K. M.; Georgeot, B.; Shepelyansky, D. L.

    2011-11-01

    The PageRank algorithm enables us to rank the nodes of a network through a specific eigenvector of the Google matrix, using a damping parameter α ∈ ]0, 1[. Using extensive numerical simulations of large web networks, with a special accent on British University networks, we determine numerically and analytically the universal features of the PageRank vector at its emergence when α → 1. The whole network can be divided into a core part and a group of invariant subspaces. For α → 1, PageRank converges to a universal power-law distribution on the invariant subspaces whose size distribution also follows a universal power law. The convergence of PageRank at α → 1 is controlled by eigenvalues of the core part of the Google matrix, which are extremely close to unity, leading to large relaxation times as, for example, in spin glasses.

  11. A Web Page Summarization for Mobile Phones

    NASA Astrophysics Data System (ADS)

    Hasegawa, Takaaki; Nishikawa, Hitoshi; Imamura, Kenji; Kikui, Gen'ichiro; Okumur, Manabu

    Recently, web pages for mobile devices are widely spread on the Internet and a lot of people can access web pages through search engines by mobile devices as well as personal computers. A summary of a retrieved web page is important because the people judge whether or not the page would be relevant to their information need according to the summary. In particular, the summary must be not only compact but also grammatical and meaningful when the users retrieve information using a mobile phone with a small screen. Most search engines seem to produce a snippet based on the keyword-in-context (KWIC) method. However, this simple method could not generate a refined summary suitable for mobile phones because of low grammaticality and content overlap with the page title. We propose a more suitable method to generate a snippet for mobile devices using sentence extraction and sentence compression methods. First, sentences are biased based on whether they include the query terms from the users or words that are relevant to the queries, as well as whether they do not overlap with the page title based on maximal marginal relevance (MMR). Second, the selected sentences are compressed based on their phrase coverage, which is measured by the scores of words, and their phrase connection probability measured based on the language model, according to the dependency structure converted from the sentence. The experimental results reveal the proposed method outperformed the KWIC method in terms of relevance judgment, grammaticality, non-redundancy and content coverage.

  12. Contrasting food-web support bases for adjoining river-influenced and non-river influenced continental shelf ecosystems

    NASA Astrophysics Data System (ADS)

    Mallin, Michael A.; Cahoon, Lawrence B.; Durako, Michael J.

    2005-01-01

    Nutrient and chlorophyll a concentrations and distributions in two adjoining regions of the South Atlantic Bight (SAB), Onslow Bay and nearshore Long Bay, were investigated over a 3-year period. Onslow Bay represents the northernmost region of the SAB, and receives very limited riverine influx. In contrast, Long Bay, just to the south, receives discharge from the Cape Fear River, draining the largest watershed within the State of North Carolina, USA. Northern Long Bay is a continental shelf ecosystem that has a nearshore area dominated by nutrient, turbidity and water-color loading from inputs from the river's plume. Average planktonic chlorophyll a concentrations ranged from 4.2 μg l -1 near the estuary mouth, to 3.1 μg l -1 7 km offshore in the plume's influence, to 1.9 μg l -1 at a non-plume station 7 km offshore to the northeast. Average areal planktonic chlorophyll a was approximately 3X that of benthic chlorophyll a at plume-influenced stations in Long Bay. In contrast, planktonic chlorophyll a concentrations in Onslow Bay were normally <0.50 μg l -1 at a nearshore (8 km) site, and <0.15 μg l -1 at sites located 45 and 100 km offshore. However, high water clarity ( KPAR 0.10-0.25 m -1) provides a favorable environment for benthic microalgae, which were abundant both nearshore (average 58.3 mg m -2) and to at least 45 km offshore in Onslow Bay (average 70.0 mg m -2) versus average concentrations of 10-12 mg m -2 for river-influenced areas of Long Bay. This provides evidence that much of the inner shelf food web in Onslow Bay is based on benthic microalgal production, in contrast to a plankton-based food web in northern Long Bay and more southerly areas of the SAB.

    An analytical methodology was developed for target analyses and broad spectrum characterization of polar contaminants such as nitrogenous and organosulfur compounds in wetlands using the complementary techniques of HPLC with electrochemical (EC) detection and tandem MS with probe and electrospray ionization. Tandem MS was well suited for the identification and quantification of mixtures of polar compounds in water samples and soil extracts, while HPLC-EC provided sensitive detection of compounds transparent to MS detection and conventional methods. The usefulness of the methodology is demonstrated by studying the removal of polar contaminants from a wetland in western Canada affected by releases of hydrocarbon-rich condensate and free product from an adjoining sour-gas plant. The concern is that the mobile water-soluble polar contaminants may not be as efficiently attenuated by volatilization or adsorption processes as the more hydrophobic hydrocarbons and that some of the polar toxic compounds may break through to contaminate groundwater and surface waters. Samples of groundwater, surface water, and aqueous soil extracts were analyzed to quantify levels of polar contaminants in the presence of high concentrations of hydrocarbons. The use of water extracts reduced the background interference from hydrocarbons and other non-polar compounds that were present in the soil samples. HPLC-EC was used to quantify the target compounds that included monoethanolamine, diethanolamine and methyldiethanolamine and sulfolane-derived compounds while tandem MS was used to identify related compounds and degradation products. Influent concentrations were in the ppm range and discharge concentrations were in the ppb range.

  14. Mutations in the Spacer Peptide and Adjoining Sequences in Rous Sarcoma Virus Gag Lead to Tubular Budding ▿

    All orthoretroviruses encode a single structural protein, Gag, which is necessary and sufficient for the assembly and budding of enveloped virus-like particles from the cell. The Gag proteins of Rous sarcoma virus (RSV) and human immunodeficiency virus type 1 (HIV-1) contain a short spacer peptide (SP or SP1, respectively) separating the capsid (CA) and nucleocapsid (NC) domains. SP or SP1 and the residues immediately upstream are known to be critical for proper assembly. Using mutagenesis and electron microscopy analysis of insect cells or chicken cells overexpressing RSV Gag, we defined the SP assembly domain to include the last 8 residues of CA, all 12 residues of SP, and the first 4 residues of NC. Five- or two-amino acid glycine-rich insertions or substitutions in this critical region uniformly resulted in the budding of abnormal, long tubular particles. The equivalent SP1-containing HIV-1 Gag sequence was unable to functionally replace the RSV sequence in supporting normal RSV spherical assembly. According to secondary structure predictions, RSV and HIV-1 SP/SP1 and adjoining residues may form an alpha helix, and what is likely the functionally equivalent sequence in murine leukemia virus Gag has been inferred by mutational analysis to form an amphipathic alpha helix. However, our alanine insertion mutagenesis did not provide evidence for an amphipathic helix in RSV Gag. Taken together, these results define a short assembly domain between the folded portions of CA and NC, which is essential for formation of the immature Gag shell. PMID:18448521

  15. Hands-on Astronomy in the Classroom: Good Teaching Ideas for Middle School, High School and Introductory College Teachers

    NASA Astrophysics Data System (ADS)

    Duncan, D.; Fraknoi, A.; Bennett, M.

    1998-05-01

    This workshop is designed to assist middle and high school teachers and astronomers who work with them or who teach introductory college courses in doing hands-on activities on astronomical topics. We will show the pioneering video, "A Private Universe ," on how students learn (and don't learn) science, and then discuss ways of aligning work in the classroomwith the way students learn best. Applying these ideas, we will work through several hands-on or inquiry-based activities that can be used directly in the classroom at the 7th - 13th (introductory college) grade level. Sample activities will make use of filters and Hubble Space Telescope slides, Doppler balls, Refraction/Reflection, spectra, etc. Participants will receive a thick package of materials, including instructions for several excellent classroom activities and resources to enhance their teaching of astronomy. Registration is required; see the AAS Education WWW page or email aased@aas.org.

  16. Computing in the Introductory Physics Course

    Chabay, Ruth; Sherwood, Bruce

    2004-03-01

    In the Matter & Interactions version of the calculus-based introductory physics course (http://www4.ncsu.edu/ ˜rwchabay/mi) , students write programs in VPython (http://vpython.org) to model physical systems and to calculate and visualize electric and magnetic fields. VPython is unusually easy to learn, produces navigable 3D animations as a side effect of physics computations, and supports full vector calculations. The high speed of current computers makes sophisticated numerical analysis techniques unnecessary. Students can use simple first-order Euler integration, cutting the step size until the behavior of the system no longer changes. In mechanics, iterative application of the momentum principle gives students a sense of the time-evolution character of Newton's second law which is usually missing from the standard course. In E, students calculate electric and magnetic fields numerically and display them in 3D. We are currently studying the impact of introducing computational physics into the introductory course.

    One of the intermediate goals of STEM education has been turning our students into problem solvers and critical thinkers who are equipped with better scientific analysis skills. In light of this initiative, it is imperative that we, the educators, modify the way we teach classic introductory physics topics, and in the long run all sciences, and offer students more opportunities to hone their forementioned STEM skills.

  19. Teaching Introductory Astronomy Using Lecture-Tutorials

    NASA Astrophysics Data System (ADS)

    Adams, Jeffrey P.; Bailey, Janelle M.; Prather, Edward E.; Slater, Timothy F.

    Contemporary science education reforms suggest that teacher-centered lectures are ineffective when compared to student-centered active learning approaches. Funded by the U.S. National Science Foundation this project has developed a series of innovative classroom instructional materials for the introductory science survey course for non-science and pre-service education majors as well as secondary school astronomy courses. The materials package called Lecture-Tutorials for Introductory Astronomy is a self-contained classroom-ready product for use with collaborative student learning groups. The materials are designed specifically to be easily integrated into the conventional lecture course. As such this product directly addresses the needs of busy faculty and heavily-loaded teaching faculty for effective student-centered classroom-ready materials that do not require a drastic course revision for implementation. Each activity requires no equipment and takes 10 to 15 minutes of class time. Students are asked to reason about difficult concepts in astronomy while working in pairs and to discuss their ideas openly. The 30 Lecture-Tutorials for Introductory Astronomy are based upon educational research on student misconceptions demonstrated effective instructional strategies and extensive pilot and field-testing. Funding for the project was made available by NSF CCLI #9952232 and NSF Geosciences Education #9907755.

    Our previous research[1] showed that despite the use of interactive engagement techniques in the introductory physics course, the gap in performance between males and females on a mechanics conceptual learning survey persisted from pre- to post-test, at our institution. Such findings were counter to previously published work[2]. Follow-up studies[3] identified correlations between student performance on the conceptual learning survey and students' prior physics and math knowledge and their incoming attitudes and beliefs about physics and learning physics. The results indicate that the gender gap at our institution is predominantly associated with differences in males' and females' previous physics and math knowledge, and attitudes and beliefs. Our current work extends these results in two ways: 1) we look at the gender gap in the second semester of the introductory sequence and find results similar to those in the first semester course and 2) we identify ways in which males and females differentially experience several aspects of the introductory course.

    Using the dual mediation hypothesis, this study investigates the role of interestingness (the power of attracting or holding one's attention) attitude towards the news, in the formation of Facebook Fan Page users' electronic word-of-mouth intentions. A total of 599 Facebook fan page users in Taiwan were recruited and structural equation modeling (SEM) was used to test the research hypotheses. The results show that both perceived news entertainment and informativeness positively influence interestingness attitude towards the news. Interestingness attitude towards the news subsequently influences hedonism and utilitarianism attitudes towards the Fan Page, which then influence eWOM intentions. Interestingness attitude towards the news plays a more important role than hedonism and utilitarianism attitudes in generating electronic word-of-mouth intentions. Based on the findings, the implications and future research suggestions are provided. PMID:24875695

    1990-01-01

    British Telecom conceived the idea of adapting their existing paging service, together with the use of existing terrestrial pagers, to yield a one way data (i.e., paging) satellite service to mobiles. The user trial of paging by satellites was successful. It demonstrated that services could be provided over a wide geographical area to low priced terminals. Many lessons were learned in unexpected areas. These include the need for extensive liaison with all users involved, especially the drivers, to ensure they understood the potential benefits. There was a significant desire for a return acknowledgement channel or even a return data channel. Above all there is a need to ensure that the equipment can be taken across European borders and legitimately used in all European countries. The next step in a marketing assessment would be to consider the impact of two way data messaging such as INMARSAT-C.

    2014-03-01

    Web technology provides a relatively easy way to generate contents for us to recognize the world, and with the development of stereoscopic display technology, the stereoscopic devices will become much more popular. The combination of web technology and stereoscopic display technology will bring revolutionary visual effect. The Stereoscopic 3D (S3D) web pages, in which text, image and video may have different depth, can be displayed on stereoscopic display devices. This paper presents the approach about how to render two viewing S3D web pages including text, images, widgets: first, an algorithm should be developed in order to display stereoscopic elements like text, widgets by using 2D graphic library; second, a method should be presented to render stereoscopic web page based on current framework of the browser; third, a rough solution is invented to fix the problem that comes out in the method.

    Bößwetter, Daniel

    Much has been written about the pros and cons of column-orientation as a means to speed up read-mostly analytic workloads in relational databases. In this paper we try to dissect the primitive mechanisms of a database that help express the coherence of tuples and present a novel way of organizing relational data in order to exploit the advantages of both, the row-oriented and the column-oriented world. As we go, we break with yet another bad habit of databases, namely the equal granularity of reads and writes which leads us to the introduction of consecutive clusters of disk pages called super-pages.

  5. Physico-chemical characterization of total suspended particulate matter over two coastal stations of Antarctica and adjoining ocean

    2015-12-01

    Physical and chemical characteristics of the total suspended particulate matter (TSPM) measured during 11 January-21 March, 2009 and 09 December 2009-09 January, 2010 over two stations of Antarctica (Larsemann Hills and Maitri) and adjoining ocean are investigated. It is found that the concentration of TSPM is low over all the observational locations. Day-to-day variation in the concentration of TSPM is mainly controlled by variation in the weather systems and associated meteorological parameters. Average concentration of TSPM over Larsemann Hills is 7.6 μg/m3 during Jan-Mar 2009 and 2.4 μg/m3 during Dec. 2009-Jan 2010. It is 9.0 μg/m3 over Maitri during Jan-Mar 2009. On excluding the TSPM data of the disturbed weather days during Jan-Mar 2009, the concentration of TSPM is found to be 4.2 μg/m3 over Larsemann Hills and 4.3 μg/m3 over Maitri. The TSPM at all the observational locations is acidic in nature with a maximum pH value of 5.56 at Larsemann Hills. The pH value of TSPM over Maitri is found to be 5.28. The acidic nature of TSPM indicates the absence of sufficient neutralizing alkaline minerals. Among the measured chemical anions Cl- dominates at all the locations except at Maitri where SO42- ion shows maximum concentration. The dominant cation is Na+ at all the observational stations. Sizeable fraction of SO42-/SUP is found at all the observational locations. Abundance of SO42 in the atmosphere of Antarctica and its surrounding region is mainly due to emission of dimethylsulfide (DMS) phytoplankton and its oxidation finally to SO42- particles by gas-to-particle conversion. The highest concentration of SO42- over Maitri is attributed to the contribution from anthropogenic activity at Maitri, in addition to the biogenic SO42-. NH4+ plays dominant role in neutralizing the acidic components of the aerosols.

    Buttler, D J; Rocco, D; Liu, L

    2004-02-20

    The Internet and the World Wide Web have enabled a publishing explosion of useful online information, which has produced the unfortunate side effect of information overload: it is increasingly difficult for individuals to keep abreast of fresh information. In this paper we describe an approach for building a system for efficiently monitoring changes to Web documents. This paper has three main contributions. First, we present a coherent framework that captures different characteristics of Web documents. The system uses the Page Digest encoding to provide a comprehensive monitoring system for content, structure, and other interesting properties of Web documents. Second, the Page Digest encoding enables improved performance for individual page monitors through mechanisms such as short-circuit evaluation, linear time algorithms for document and structure similarity, and data size reduction. Finally, we develop a collection of sentinel grouping techniques based on the Page Digest encoding to reduce redundant processing in large-scale monitoring systems by grouping similar monitoring requests together. We examine how effective these techniques are over a wide range of parameters and have seen an order of magnitude speed up over existing Web-based information monitoring systems.

    This article sets out some of the rationale and arguments for making major changes to the teaching and learning of statistical inference in introductory courses at our universities by changing from a norm-based, mathematical approach to more conceptually accessible computer-based approaches. The core problem of the inferential argument with its hypothetical probabilistic reasoning process is examined in some depth. We argue that the revolution in the teaching of inference must begin. We also discuss some perplexing issues, problematic areas and some new insights into language conundrums associated with introducing the logic of inference through randomization methods.

  20. The Pythagorean Roots of Introductory Physics

    NASA Astrophysics Data System (ADS)

    Clarage, James B.

    2013-03-01

    Much of the mathematical reasoning employed in the typical introductory physics course can be traced to Pythagorean roots planted over two thousand years ago. Besides obvious examples involving the Pythagorean theorem, I draw attention to standard physics problems and derivations which often unknowingly rely upon the Pythagoreans' work on proportion, music, geometry, harmony, the golden ratio, and cosmology. Examples are drawn from mechanics, electricity, sound, optics, energy conservation and relativity. An awareness of the primary sources of the mathematical techniques employed in the physics classroom could especially benefit students and educators at schools which encourage integration of their various courses in history, science, philosophy, and the arts.

    2016-02-01

    Facebook has been used in health research, but there is a lack of literature regarding how Facebook may be used to recruit younger adolescents. A Facebook Page was created for an adolescent cohort study on the effects of puberty hormones on well-being and behaviour in early adolescence. Used as a communication tool with existing participants, it also aimed to alert potential participants to the study. The purpose of this paper is to provide a detailed description of the development of the study Facebook Page and present the fan response to the types of posts made on the Page using the Facebook-generated Insights data. Two types of posts were made on the study Facebook Page. The first type was study-related update posts and events. The second was relevant adolescent and family research and current news posts. Observations on the use of and response to the Page were made over 1 year across three phases (phase 1, very low Facebook use; phase 2, high Facebook use; phase 3, low Facebook use). Most Page fans were female (88.6%), with the largest group of fans aged between 35 and 44 years. Study-related update posts with photographs were the most popular. This paper provides a model on which other researchers could base Facebook communication and potential recruitment in the absence of established guidelines. PMID:25781667

    PubMed

    Dall'Acqua, F; Paladini, C; Meiswinkel, R; Savini, L; Calistri, P

    2006-01-01

    During the recent severe outbreaks of bluetongue (BT) in the Mediterranean Basin, the BT virus (BTV) spread beyond its historical limits into the Balkan region. One of the primary impacts of BT is the cessation in livestock trade which can have severe economic and social consequences. The authors briefly describe the development of the collaborative East-BTnet programme which aims to assist all affected and at-risk Balkan states and adjoining countries in the management of BT, and in the development of individual national surveillance systems. The beneficiary countries involved, and led by the World organisation for animal health (Office International des Epizooties) Collaborating Centre for veterinary training, epidemiology, food safety and animal welfare of the Istituto Zooprofilattico dell'Abruzzo e del Molise 'G. Caporale' in collaboration with the Institute for the Protection and the Security of the Citizen, the European Commission Joint Research Centre (IPSC-JRC), were Albania, Bosnia-Herzegovina, Bulgaria, Croatia, Cyprus, the Former Yugoslavia Republic of Macedonia, Kosovo, Malta, Romania, Serbia and Montenegro, Slovenia and Turkey. A regional web-based surveillance network is a valuable tool for controlling and managing transboundary animal diseases such as BT. Its implementation in the Balkan region and in adjoining areas of south-eastern Europe is described and discussed. PMID:20429055

  16. Introductory Physics Experiments Using the Wiimote

    NASA Astrophysics Data System (ADS)

    Somers, William; Rooney, Frank; Ochoa, Romulo

    2009-03-01

    The Wii, a video game console, is a very popular device with millions of units sold worldwide over the past two years. Although computationally it is not a powerful machine, to a physics educator its most important components can be its controllers. The Wiimote (or remote) controller contains three accelerometers, an infrared detector, and Bluetooth connectivity at a relatively low price. Thanks to available open source code, any PC with Bluetooth capability can detect the information sent out by the Wiimote. We have designed several experiments for introductory physics courses that make use of the accelerometers and Bluetooth connectivity. We have adapted the Wiimote to measure the: variable acceleration in simple harmonic motion, centripetal and tangential accelerations in circular motion, and the accelerations generated when students lift weights. We present the results of our experiments and compare them with those obtained when using motion and/or force sensors.

  17. The laboratory experience in introductory physics courses

    NASA Astrophysics Data System (ADS)

    Di Stefano, Maria C.

    1997-03-01

    The last two decades or so have witnessed intense efforts to improve the teaching and learning of physics. Scholarly studies have provided the grounding for many projects which reform the structure of introductory courses. A number of these innovations, however, are resource intensive, or depend on the ability to introduce changes in areas which are beyond the control of the faculty (e.g., scheduling), thus inhibiting their implementation. An alternative strategy that overcomes these obstacles is to modify the nature of the laboratory experience (a component that practically nobody disputes is an essential part of the introductory course), to provide hands-on learning opportunities that differ from the traditional "follow-this-recipe-to-verify-this-law" approach. I have chosen to implement a variety of activities that support the overall objectives of the course: developing conceptual understanding and transferable skills, and providing practice in the ways scientists actually do science. Given the audience in this two-semester, algebra-based course, mostly biology majors and pre-professionals (health-related careers, such as medicine, physical therapy, and veterinary), these goals were identified as the most important and lasting contribution that a physics course can make to the students intellectual development. I offer here examples of the types of hands on activities that I have implemented, organized for the sake of this presentation in four rather loose categories, depending on which subset of the course objectives the activities mostly address: self-designed lab activities, discussion of demo-type activities, building concepts from simple to complex, and out-of-lab physical phenomena.

  18. Analyzing the impact of course structure on electronic textbook use in blended introductory physics courses

    NASA Astrophysics Data System (ADS)

    Seaton, Daniel T.; Kortemeyer, Gerd; Bergner, Yoav; Rayyan, Saif; Pritchard, David E.

    2014-12-01

    We investigate how elements of course structure (i.e., the frequency of assessments as well as the sequencing and weight of course resources) influence the usage patterns of electronic textbooks (e-texts) in introductory physics courses. Specifically, we analyze the access logs of courses at Michigan State University and the Massachusetts Institute of Technology, each of which deploy e-texts as primary or secondary texts in combination with different formative assessments (e.g., embedded reading questions) and different summative assessment (exam) schedules. As such studies are frequently marred by arguments over what constitutes a "meaningful" interaction with a particular page (usually judged by how long the page remains on the screen), we consider a set of different definitions of "meaningful" interactions. We find that course structure has a strong influence on how much of the e-texts students actually read, and when they do so. In particular, courses that deviate strongly from traditional structures, most notably by more frequent exams, show consistently high usage of the materials with far less "cramming" before exams.

  19. Use of camera drive in stereoscopic display of learning contents of introductory physics

    NASA Astrophysics Data System (ADS)

    Matsuura, Shu

    2011-03-01

    Simple 3D physics simulations with stereoscopic display were created for a part of introductory physics e-Learning. First, cameras to see the 3D world can be made controllable by the user. This enabled to observe the system and motions of objects from any position in the 3D world. Second, cameras were made attachable to one of the moving object in the simulation so as to observe the relative motion of other objects. By this option, it was found that users perceive the velocity and acceleration more sensibly on stereoscopic display than on non-stereoscopic 3D display. Simulations were made using Adobe Flash ActionScript, and Papervison 3D library was used to render the 3D models in the flash web pages. To display the stereogram, two viewports from virtual cameras were displayed in parallel in the same web page. For observation of stereogram, the images of two viewports were superimposed by using 3D stereogram projection box (T&TS CO., LTD.), and projected on an 80-inch screen. The virtual cameras were controlled by keyboard and also by Nintendo Wii remote controller buttons. In conclusion, stereoscopic display offers learners more opportunities to play with the simulated models, and to perceive the characteristics of motion better.

    2015-02-01

    In this paper we will try to define the utility of Facebook's Personal Page marketing method. This tool that Facebook provides, is modelled and simulated using iThink in the context of a Facebook marketing agency. The paper has leveraged the system's dynamic paradigm to conduct Facebook marketing tools and methods modelling, using iThink™ system to implement them. It uses the design science research methodology for the proof of concept of the models and modelling processes. The following model has been developed for a social media marketing agent/company, Facebook platform oriented and tested in real circumstances. This model is finalized through a number of revisions and iterators of the design, development, simulation, testing and evaluation processes. The validity and usefulness of this Facebook marketing model for the day-to-day decision making are authenticated by the management of the company organization. Facebook's Personal Page method can be adjusted, depending on the situation, in order to maximize the total profit of the company which is to bring new customers, keep the interest of the old customers and deliver traffic to its website.

  6. NRC PAGE. Sequential Analysis Materials Balance

    SciTech Connect

    Picard, R.

    1992-01-13

    NRCPAGE is used in safeguards applications to detect a recurring loss of special nuclear material by frequent evaluation (sequential analysis) of accountability data. Standard sequential testing procedures are traditionally based on sequences of independent and normally distributed measurements. This same approach can be applied to materials balance (MB) data. Here, the term materials balance has a meaning similar to inventory difference and represents a materials loss indicator localized in time and space. However, distinct MBs cannot be reasonably treated as statistically independent and may not always be reasonably treated as normally distributed. Furthermore, the covariance structure associated with a given MB sequence is not known and must be estimated. Nonindependence is treated by converting the MB sequence to the innovation sequence, sometimes called the ITMUF sequence or the sequence of MUF residuals, which are statistically independent and amenable to sequential test procedures. A one-sided page`s test, effective for a wide range of recurring loss scenarios, is applied to the standardized innovation sequence. The program can be easily modified to suit particular needs; the models for the assumption of multivariate normality for MBs when computing the innovation sequence or the test procedure can be changed as can the input/output format, dimensioning, local error checking, and simulation work. Input files can be sequentially constructed using local text editors to update existing files. Output files can be read by graphics, report writer, or other stand-alone utility routines.

    Bora, Dipok K.; Baruah, Saurabh

    2012-04-01

    In this study we have tried to detect and collect later phases associated with Moho discontinuity and used them to study the lateral variations of the crustal thickness in Shillong-Mikir Hills Plateau and its adjoining region of northeastern India. We use the inversion algorithm by Nakajima et al. (Nakajima, J., Matsuzawa, T., Hasegawa, A. 2002. Moho depth variation in the central part of northeastern Japan estimated from reflected and converted waves. Physics of the Earth and Planetary Interiors, 130, 31-47), having epicentral distance ranging from 60 km to 150 km. Taking the advantage of high quality broadband data now available in northeast India, we have detected 1607 Moho reflected phases (PmP and SmS) from 300 numbers of shallow earthquake events (depth ⩽ 25 km) in Shillong-Mikir Hills Plateau and its adjoining region. Notably for PmP phase, this could be identified within 0.5-2.3 s after the first P-arrival. In case of SmS phase, the arrival times are observed within 1.0-4.2 s after the first S-arrival. We estimated the crustal thickness in the study area using travel time difference between the later phases (PmP and SmS) and the first P and S arrivals. The results shows that the Moho is thinner beneath the Shillong Plateau about 35-38 km and is the deepest beneath the Brahmaputra valley to the north about 39-41 km, deeper by 4-5 km compared to the Shillong Plateau with simultaneous observation of thinnest crust (˜33 km) in the western part of the Shillong Plateau in the Garo Hills region.

  6. Using Computers in Introductory Astronomy Courses

    NASA Astrophysics Data System (ADS)

    Deming, Grace L.

    1995-12-01

    Computer literacy is fast becoming a focal point in undergraduate education. Scientific literacy has been a continuing goal of undergraduate programs across the nation and a course in introductory astronomy is often used to satisfy such science requirements. At U. MD an introduction to computer skills is being integrated into our astronomy curriculum for non-science majors. The campus is adequately equipped with computer labs, yet many students enter college without basic computer skills. In Astronomy 101 (General Astronomy) students are introduced to electronic mail, a Listserver, and the world wide web. Students in this course are required to register for a free campus computer account. Their first assignment is to use e-mail to subscribe to the class Listserver, Milkyway. Through Milkyway, students have access to weekly lecture summaries, questions to review for exams, and copies of previous exams. Using e-mail students may pose questions, provide comments, or exchange opinions using Milkyway, or they may e-mail the instructor directly. Studies indicate that using e-mail is less intimidating to a student than asking a question in a class of 200 students. Monitoring e-mail for student questions has not been a problem. Student reaction has been favorable to using e-mail, since instructor office hours are not always convenient, especially to commuting or working students. Through required assignments, students receive an introduction to accessing information on the world wide web using Netscape. Astronomy has great resources available on the Internet which can be used to supplement and reinforce introductory material. Assignments are structured so that students will gain the techniques necessary to access available information. It is hoped that students will successfully apply the computer skills they learn in astronomy class to their own fields and as life-long learners. We have found that students comfortable with computers are willing to share their knowledge

  7. Tutorials in Introductory Physics: The Pain and the Gain

    In an introductory physics sequence with a large enrollment of premedical students, traditional recitation sessions were replaced by Tutorials in Introductory Physics, developed by the Physics Education Group at the University of Washington. Initially, summative test scores (as well as FCI scores) dramatically increased, but so did student complaints and workload. Both effects decreased over time. The paper discusses issues that instructors should consider when contemplating implementation of the tutorials.

    The circular twin paradox and Thomas precession are presented in a way that makes them accessible to students in introductory relativity courses. Both are discussed by examining what happens during travel around a polygon and then in the limit as the polygon becomes a circle. Because relativistic predictions based on these examples are verified in experiments with macroscopic objects (such as atomic clocks flown in airplanes and the gyroscopes on Gravity Probe B), they are especially convincing to introductory students.

    While it is well known which curricular practices can improve student performance on measures of conceptual understanding, the sustaining of these practices and the role of faculty members in implementing these practices are less well understood. We present a study of the hand-off of Tutorials in Introductory Physics [McDermott and Schaffer (Prentice-Hall, Upper Saddle River, NJ, 2002)] from initial adopters to other instructors at the University of Colorado, including traditional faculty not involved in physics educational research. The study examines the impact of implementation of tutorials on student conceptual learning across ten first-semester, and seven second-semester courses, for 15 faculty members over 13 semesters, and includes roughly 5000 students. It is possible to demonstrate consistently high, and statistically indistinguishable, student learning gains for different faculty members; however, such results are not the norm and appear to rely on a variety of factors. Student performance varies by faculty background—faculty involved in, or informed by physics education research, consistently post higher student learning gains than less-informed faculty. Student performance in these courses also varies by curricula used—all semesters in which the research-based Tutorials and learning assistants are used have higher student learning gains than those semesters that rely on nonresearch-based materials and do not employ learning assistants.

    1993-12-01

    In an attempt to offer undergraduate students a means of visualizing some of the dynamical, geometric, evolutionary, and spectroscopic concepts encountered in introductory astronomy and astrophysics courses, we have developed a set of ten computer modules intended for the interactive investigation of these concepts in a learning center equipped with a cluster of Unix-based workstations. We present six of these software teaching tools: Galaxy (rotation curves), Redshift (line identifications, redshift determinations, and construction of a Hubble plot), Sky View (an on-screen planetarium), Stellar Evolution (dynamic trajectories in the HR diagram), Parallax (parallactic ellipses and proper motions), and Binaries (eclipsing binary light curves and projected appearances evolving with orbital phase). Developed for the X-windows interface on Unix-based workstations for maximum portability and speed, these programs, along with accompanying instruction sets, guide the student through multi-step exercises designed to demonstrate these basic ideas. The sophistication of the modules is advanced enough to permit their utilization in courses spanning a wide range of skill levels with suitable tailoring of the instruction sets. The use of these modules in lower division astronomy and astrophysics classes at UCLA has been met with positive student reviews. We anticipate increased usage as the package of modules grows. Upon request, it can be exported to other institutions. The development of the package has been supported by NSF.

  11. Teaching Technolgies for the Introductory Physics Classroom

    At Duke University we use several technologies in the Introductory Physics Courses for Life Sciences Majors. These tools assist the instructors in obtaining formative assessments of student understanding and provide students with feedback during each week of the semester. PreLecture and Survey assignments are delivered via the Web using the BlackBoard course management program. In addition, infrared transmitters (aka Personal Response System, PRS) have been used in classroom to poll conceptual and computational questions relating to reading assignments, to examples worked in lecture and to demonstrations that have been (or will be) done for the students. The instructor may choose to review the material or to move on to subsequent topics with greater confidence that the students are fully prepared method encouraged by the Just In Time Teaching model. On occasion, the initial response distribution is hidden in order to encourage Instruction between the students before the question is repolled. From these experiences students may see shifts in their understanding (or instructors can confirm the persistence of misconceptions!). Data obtained from the courses reveal interesting correlations between polling scores, prior AP experiences, gender and the overall grades earned in the courses.

    Introductory psychology (Intro Psych) is one of the most popular and frequently taught courses on college campuses, yet educators in psychology have limited knowledge about what is covered in classes around the nation or the extent to which class content reflects the current scope of the discipline. There is no explicit model to guide course content selection for the intro course, which poses substantial challenges for instructors. This article proposes a new model for teaching the intro course that integrates (a) scientific foundations, (b) 5 major domains or pillars of knowledge (biological, cognitive, developmental, social and personality, and mental and physical health), and (c) cross-cutting themes relevant to all domains (cultural and social diversity, ethics, variations in human functioning, and applications; American Psychological Association, 2014). We advocate for national assessment of the course, a similar introductory course for majors and nonmajors, the inclusion of experiential or laboratory components, and additional training resources for instructors of the intro course. Given the exponential growth of psychological knowledge and applications during the past decades, we caution against attempting to provide exhaustive coverage of all topic areas of psychology in a one-semester course. We conclude by discussing the challenges that lie ahead for the discipline of psychology as it launches this new model for Intro Psych. PMID:26866987

  13. Calibrating page sized Gafchromic EBT3 films

    2013-01-15

    Purpose: The purpose is the development of a novel calibration method for dosimetry with Gafchromic EBT3 films. The method should be applicable for pretreatment verification of volumetric modulated arc, and intensity modulated radiotherapy. Because the exposed area on film can be large for such treatments, lateral scan errors must be taken into account. The correction for the lateral scan effect is obtained from the calibration data itself. Methods: In this work, the film measurements were modeled using their relative scan values (Transmittance, T). Inside the transmittance domain a linear combination and a parabolic lateral scan correction described the observed transmittance values. The linear combination model, combined a monomer transmittance state (T{sub 0}) and a polymer transmittance state (T{sub {infinity}}) of the film. The dose domain was associated with the observed effects in the transmittance domain through a rational calibration function. On the calibration film only simple static fields were applied and page sized films were used for calibration and measurements (treatment verification). Four different calibration setups were considered and compared with respect to dose estimation accuracy. The first (I) used a calibration table from 32 regions of interest (ROIs) spread on 4 calibration films, the second (II) used 16 ROIs spread on 2 calibration films, the third (III), and fourth (IV) used 8 ROIs spread on a single calibration film. The calibration tables of the setups I, II, and IV contained eight dose levels delivered to different positions on the films, while for setup III only four dose levels were applied. Validation was performed by irradiating film strips with known doses at two different time points over the course of a week. Accuracy of the dose response and the lateral effect correction was estimated using the dose difference and the root mean squared error (RMSE), respectively. Results: A calibration based on two films was the optimal

  14. Examining issues of underrepresented minority students in introductory physics

    NASA Astrophysics Data System (ADS)

    Watkins, Jessica Ellen

    In this dissertation we examine several issues related to the retention of under-represented minority students in physics and science. In the first section, we show that in calculus-based introductory physics courses, the gender gap on the FCI is diminished through the use of interactive techniques, but in lower-level introductory courses, the gap persists, similar to reports published at other institutions. We find that under-represented racial minorities perform similar to their peers with comparable academic preparation on conceptual surveys, but their average exam grades and course grades are lower. We also examine student persistence in science majors; finding a significant relationship between pedagogy in an introductory physics course and persistence in science. In the second section, we look at student end-of-semester evaluations and find that female students rate interactive teaching methods a full point lower than their male peers. Looking more deeply at student interview data, we find that female students report more social issues related to the discussions in class and both male and female students cite feeling pressure to obtain the correct answer to clicker questions. Finally, we take a look an often-cited claim for gender differences in STEM participation: cognitive differences explain achievement differences in physics. We examine specifically the role of mental rotations in physics achievement and problem-solving, viewing mental rotations as a tool that students can use on physics problems. We first look at student survey results for lower-level introductory students, finding a low, but significant correlation between performance on a mental rotations test and performance in introductory physics courses. In contrast, we did not find a significant relationship for students in the upper-level introductory course. We also examine student problem-solving interviews to investigate the role of mental rotations on introductory problems.

    Introductory undergraduate courses play a pivotal role in the geosciences. They serve as recruiting grounds for majors and future professionals, provide relevant experiences in geoscience for pre-service teachers, and offer opportunities to influence future policy makers, business people, professionals, and citizens. An introductory course is also typically the only course in geoscience that most of our students will ever take. Because the role of introductory courses is pivotal in geoscience education, a workshop on Teaching Introductory Courses in the 21st Century was held in July 2008 as part of the On the Cutting Edge faculty development program. A website was also developed in conjunction with the workshop. One of the central themes of the workshop was the importance of considering the long-term impact a course should have on students. Ideally, courses can be designed with this impact in mind. Approaches include using the local geology to focus the course and illustrate concepts; designing a course for particular audience (such as Geology for Engineers); creating course features that help students understand and interpret geoscience in the news; and developing capstone projects to teach critical thinking and problem solving skills in a geologic context. Workshop participants also explored strategies for designing engaging activities including exploring with Google Earth, using real-world scenarios, connecting with popular media, or making use of campus features on local field trips. In addition, introductory courses can emphasize broad skills such as teaching the process of science, using quantitative reasoning and developing communication skills. Materials from the workshop as well as descriptions of more than 150 introductory courses and 350 introductory-level activities are available on the website: http://serc.carleton.edu/NAGTWorkshops/intro/index.html.

  16. Introductory Tools for Radiative Transfer Models

    Satellite data are currently so voluminous that, despite their unprecedented quality and potential for scientific application, only a small fraction is analyzed due to two factors: researchers' computational constraints and a relatively small number of researchers actively utilizing the data. Ultimately it is hoped that the terabytes of unanalyzed data being archived can receive scientific scrutiny but this will require a popularization of the methods associated with the analysis. Since a large portion of complexity is associated with the proper implementation of the radiative transfer model, it is reasonable and appropriate to make the model as accessible as possible to general audiences. Unfortunately, the algorithmic and conceptual details that are necessary for state-of-the-art analysis also tend to frustrate the accessibility for those new to remote sensing. Several efforts have been made to have web- based radiative transfer calculations, and these are useful for limited calculations, but analysis of more than a few spectra requires the utilization of home- or server-based computing resources. We present a system that is designed to allow for easier access to radiative transfer models with implementation on a home computing platform in the hopes that this system can be utilized in and expanded upon in advanced high school and introductory college settings. This learning-by-doing process is aided through the use of several powerful tools. The first is a wikipedia-style introduction to the salient features of radiative transfer that references the seminal works in the field and refers to more complicated calculations and algorithms sparingly5. The second feature is a technical forum, commonly referred to as a tiki-wiki, that addresses technical and conceptual questions through public postings, private messages, and a ranked searching routine. Together, these tools may be able to facilitate greater interest in the field of remote sensing.

    2002-05-01

    In the fall of 2001, learner centered education principles were applied to an introductory astronomy course at the Superstition Mountain Campus of Central Arizona College (CAC). The course was cooperatively designed and managed by the students themselves (especially Sprague and Grill), an assistant course facilitator (C. Genet), and the course instructor and developer (R. Genet). Although some time was devoted to lectures accompanied by photographic slides and open to the public, the bulk of the time was devoted to student projects. Students built telescopes, including solar, zenith, and Galileo, took measurements, made calculations, mapped stars, and determined the circumference of the earth via zenith observations at Apache Junction and at Mt. Hopkins, 120 miles away. A three-day field trip to Lowell Observatory included a tour, observations through the famous 24-inch Clark refractor, and a conference on `Undergraduate Astronomical Research' which included talks on stellar photometry by G. W. Lockwood and R. M. Genet. A second three-day field trip included a tour and observations at Kitt Peak National Observatory (0.4 m telescope), a tour of the observatories on Mt. Hopkins, and a conference on `Learner-Centered Astronomy Education.' The community college students were joined by doctoral students and alumni from the Union Institute and University, as well as by Campua Dean James Stuckey from CAC and his wife Beverly Santos of Northern Arizona University. By allowing students the freedom to explore and expand their knowledge at a rate appropriate to each individual, the students attained levels of confidence not found in traditional teaching styles. We are pleased to acknowledge Dean Stuckey who made this class possible. We also wish to thank Wesley Lockwood and Robert Bargoon at Lowell Observatory, Robert Wilson at Kitt Peak National Observatory, and Daniel Brocious at the Smithsonian's Whipple Observatory for their invaluable assistance during our field trips.

    Uniformity is one of the issues of most critical concern for laser electrophotographic (EP) printers. Typically, full coverage constant-tint test pages are printed to assess uniformity. Exemplary nonuniformity defects include mottle, grain, pinholes, and "finger prints". It is a real challenge to make an overall Print Quality (PQ) assessment due to the large coverage of a letter-size, constant-tint printed test page and the variety of possible nonuniformity defects. In this paper, we propose a novel method that uses a block-based technique to analyze the page both visually and metrically. We use a grid of 150 pixels × 150 pixels ( ¼ inch × ¼ inch at 600-dpi resolution) square blocks throughout the scanned page. For each block, we examine two aspects: behavior of its pixels within the block (metrics of graininess) and behavior of the blocks within the printed page (metrics of nonuniformity). Both ΔE (CIE 1976) and the L* lightness channel are employed. For an input scanned page, we create eight visual outputs, each displaying a different aspect of nonuniformity. To apply machine learning, we train scanned pages of different 100% solid colors separately with the support vector machine (SVM) algorithm. We use two metrics as features for the SVM: average dispersion of page lightness and standard deviation in dispersion of page lightness. Our results show that we can predict, with 83% to 90% accuracy, the assignment by a print quality expert of one of two grades of uniformity in the print.

  19. Work Habits of Students in Traditional and Online Sections of an Introductory Physics Course: A Case Study

    The study compares the work habits of two student groups in an introductory physics course, one in traditional and one in online sections. Both groups shared the same online materials and online homework, as well as the same discussion boards and examinations, but one group in addition had traditional lectures. The groups were compared with respect to amount and frequency of access to different online course resources. It was found that with few exceptions, both groups exhibited very similar work habits. Students in the online sections more frequently accessed content pages and more frequently contributed to course discussions. It was also found that regular access of the materials throughout the week, rather than only on homework deadline nights, is a predictor of success on examinations, and that this indicator is more reliable for students in the online sections. Overall, though, the effect of traditional lectures is minimal.

    Crouch, Catherine H.; Heller, Kenneth

    2014-05-01

    We describe restructuring the introductory physics for life science students (IPLS) course to better support these students in using physics to understand their chosen fields. Our courses teach physics using biologically rich contexts. Specifically, we use examples in which fundamental physics contributes significantly to understanding a biological system to make explicit the value of physics to the life sciences. This requires selecting the course content to reflect the topics most relevant to biology while maintaining the fundamental disciplinary structure of physics. In addition to stressing the importance of the fundamental principles of physics, an important goal is developing students' quantitative and problem solving skills. Our guiding pedagogical framework is the cognitive apprenticeship model, in which learning occurs most effectively when students can articulate why what they are learning matters to them. In this article, we describe our courses, summarize initial assessment data, and identify needs for future research.

  1. Designing an Introductory Physics Course for Biological Science Students

    NASA Astrophysics Data System (ADS)

    Heller, Kenneth

    2009-05-01

    For the past four years the School of Physics and Astronomy at the University of Minnesota has been revising its Introductory Physics Course specifically targeted to biological science and pre-medical students. The course design process includes determining the reasons that introductory physics is required by the biology faculty and determining how or if to satisfy their goals. The resulting course must substantially satisfy the goals of the biology faculty, be an introductory physics course that stresses the application of fundamental principles and relates them to complex situations typical in biology, be of interest to beginning biology students, and be teachable by ordinary physics professors. The design process for the content and the pedagogy of the course will be described as will the resulting course structure. Student performance measures for the revised course will also be given.

  2. Engaging Students In Modeling Instruction for Introductory Physics

    Brewe, Eric

    2016-05-01

    Teaching introductory physics is arguably one of the most important things that a physics department does. It is the primary way that students from other science disciplines engage with physics and it is the introduction to physics for majors. Modeling instruction is an active learning strategy for introductory physics built on the premise that science proceeds through the iterative process of model construction, development, deployment, and revision. We describe the role that participating in authentic modeling has in learning and then explore how students engage in this process in the classroom. In this presentation, we provide a theoretical background on models and modeling and describe how these theoretical elements are enacted in the introductory university physics classroom. We provide both quantitative and video data to link the development of a conceptual model to the design of the learning environment and to student outcomes. This work is supported in part by DUE #1140706.

    1998-04-01

    Director (from Macromedia) is a powerful software tool for developing multimedia animations and simulations in physics. In this paper, we present some of the modules that we have developed for a conceptual physics course which will be offered on the web as well as on a LAN server. These modules, written in Lingo (the scripting language of Director), are aimed at improving students understanding of different concepts in introductory physics. Their main feature is their simplicity, clear presentation, emphasis on qualitative concepts, and most importantly, their interactivity. We will describe how these animations may be icorporated in introductory physics courses.

  15. Use of The Math You Need When You Need It website outside of introductory geoscience courses

    NASA Astrophysics Data System (ADS)

    Baer, E. M.; Wenner, J. M.

    2011-12-01

    Web usage statistics and a recent survey of visitors to The Math You Need, When You Need It (TMYN) suggest that these web resources serve a significant number of students beyond those for whom they were originally intended. The web-based modules of TMYN are asynchronous online resources designed to help undergraduates learn quantitative concepts essential in a concurrent introductory geoscience course. In the past year, approximately 1,000 students accessed TMYN through associated geoscience courses; however, in that same time period,more than 40 times that number interacted significantly with the site according to Google Analytics. Of the nearly 220,000 total visitors, ~15% stayed on the site for longer than one minute and ~20% visited two or more pages within the site, suggesting that the content is engaging and useful to many of the visitors. In a pop-up survey of users, 81% of the nearly 350 respondents reported that they found what they were looking for. Although the nature of TMYN website users is difficult to discern definitively, daily, weekly and monthly use patterns indicate a predominance of academic users. Access to the site is lowest during the summer months and on Friday and Saturday, and is elevated on Sunday through Thursdays. Furthermore, in a pop-up survey of users who accessed more than one page, greater than half (56%) of the 346 respondents were students, 20% collegiate faculty and 9% K-12 teachers. Although the resources are specifically designed for geoscience students, 61% of survey respondents identified themselves as associated with other STEM disciplines. Thus, despite the decidedly geoscientific slant to these resources, survey data suggest that many STEM students and teachers are searching for the kinds of topics covered by TMYN. Furthermore, web use statistics indicate a substantial need for high quality web-based quantitative skill support materials for all STEM disciplines.

  3. An Efficient Web Page Ranking for Semantic Web

    NASA Astrophysics Data System (ADS)

    Chahal, P.; Singh, M.; Kumar, S.

    2014-01-01

    With the enormous amount of information presented on the web, the retrieval of relevant information has become a serious problem and is also the topic of research for last few years. The most common tools to retrieve information from web are search engines like Google. The Search engines are usually based on keyword searching and indexing of web pages. This approach is not very efficient as the result-set of web pages obtained include large irrelevant pages. Sometimes even the entire result-set may contain lot of irrelevant pages for the user. The next generation of search engines must address this problem. Recently, many semantic web search engines have been developed like Ontolook, Swoogle, which help in searching meaningful documents presented on semantic web. In this process the ranking of the retrieved web pages is very crucial. Some attempts have been made in ranking of semantic web pages but still the ranking of these semantic web documents is neither satisfactory and nor up to the user's expectations. In this paper we have proposed a semantic web based document ranking scheme that relies not only on the keywords but also on the conceptual instances present between the keywords. As a result only the relevant page will be on the top of the result-set of searched web pages. We explore all relevant relations between the keywords exploring the user's intention and then calculate the fraction of these relations on each web page to determine their relevance. We have found that this ranking technique gives better results than those by the prevailing methods.

  4. Exploring the use of a Facebook page in anatomy education.

    PubMed

    Jaffar, Akram Abood

    2014-01-01

    Facebook is the most popular social media site visited by university students on a daily basis. Consequently, Facebook is the logical place to start with for integrating social media technologies into education. This study explores how a faculty-administered Facebook Page can be used to supplement anatomy education beyond the traditional classroom. Observations were made on students' perceptions and effectiveness of using the Page, potential benefits and challenges of such use, and which Insights metrics best reflect user's engagement. The Human Anatomy Education Page was launched on Facebook and incorporated into anatomy resources for 157 medical students during two academic years. Students' use of Facebook and their perceptions of the Page were surveyed. Facebook's "Insights" tool was also used to evaluate Page performance during a period of 600 days. The majority of in-class students had a Facebook account which they adopted in education. Most students perceived Human Anatomy Education Page as effective in contributing to learning and favored "self-assessment" posts. The majority of students agreed that Facebook could be a suitable learning environment. The "Insights" tool revealed globally distributed fans with considerable Page interactions. The use of a faculty-administered Facebook Page provided a venue to enhance classroom teaching without intruding into students' social life. A wider educational use of Facebook should be adopted not only because students are embracing its use, but for its inherent potentials in boosting learning. The "Insights" metrics analyzed in this study might be helpful when establishing and evaluating the performance of education-oriented Facebook Pages. PMID:24022984

  16. A Survey of Learning Goals for Introductory Astronomy Courses

    NASA Astrophysics Data System (ADS)

    Brissenden, G.; Duncan, D. K.; Greenfield, J. L.; Slater, T. F.

    1999-05-01

    Introductory astronomy for non-science majors is delivered to more than 200,000 students each year in small colleges and large research universities alike. Not always taught by PhDs formally trained in astronomy, previous surveys reveal that introductory astronomy for undergraduate non-science majors is often taught by individuals trained in physics, mathematics, geology, among many other fields. Such a diversity in instructor backgrounds suggests that there might exist a wide diversity in course goals, learning objectives, and topics covered in such a course. In an attempt to explore this diversity, two projects were conducted simultaneously. First, astronomy instructors pre-registered to attend the ASTR 101 teaching workshop at the 1998 ASP Albuquerque meeting were asked to electronically submit their three main course goals for introductory astronomy. Fifty-four responses showed a convergence of several ideas across the majority of instructors: an understanding of the nature of science and astronomy, an appreciation for the size, scale, and structure of the cosmos, and an increased interest in studying current events in astronomy as a life-long learning activity. Second, an analysis of 50 introductory astronomy syllabi found on the World-Wide-Web was conducted to determine the frequency that 75 possible topics in introductory astronomy were evidently included in the course. The most common topics covered appear to be the nature of light and the electromagnetic spectrum, stellar evolution and the Sun, techniques and tools of astronomy, motions and objects in the solar system, and the stellar magnitude scale. Topics that appear to receive little emphasis include the reason for seasons, planetary atmospheres, plate tectonics, space exploration, and formation of the elements. Additionally, 78 indicate that night observations are required and 38 require the use of the computer or the Internet.

  17. The Dependency of Probabilistic Tsunami Hazard Assessment on Magnitude Limits of Seismic Sources in the South China Sea and Adjoining Basins

    The South China Sea (SCS) and its adjacent small basins including Sulu Sea and Celebes Sea are commonly identified as tsunami-prone region by its historical records on seismicity and tsunamis. However, quantification of tsunami hazard in the SCS region remained an intractable issue due to highly complex tectonic setting and multiple seismic sources within and surrounding this area. Probabilistic Tsunami Hazard Assessment (PTHA) is performed in the present study to evaluate tsunami hazard in the SCS region based on a brief review on seismological and tsunami records. 5 regional and local potential tsunami sources are tentatively identified, and earthquake catalogs are generated using Monte Carlo simulation following the Tapered Gutenberg-Richter relationship for each zone. Considering a lack of consensus on magnitude upper bound on each seismic source, as well as its critical role in PTHA, the major concern of the present study is to define the upper and lower limits of tsunami hazard in the SCS region comprehensively by adopting different corner magnitudes that could be derived by multiple principles and approaches, including TGR regression of historical catalog, fault-length scaling, tectonic and seismic moment balance, and repetition of historical largest event. The results show that tsunami hazard in the SCS and adjoining basins is subject to large variations when adopting different corner magnitudes, with the upper bounds 2-6 times of the lower. The probabilistic tsunami hazard maps for specified return periods reveal much higher threat from Cotabato Trench and Sulawesi Trench in the Celebes Sea, whereas tsunami hazard received by the coasts of the SCS and Sulu Sea is relatively moderate, yet non-negligible. By combining empirical method with numerical study of historical tsunami events, the present PTHA results are tentatively validated. The correspondence lends confidence to our study. Considering the proximity of major sources to population-laden cities

  18. Comparison of 19th century ship log wind data and adjoining land-based Royal Observatory data (1843 to 1855): Spot the difference?

    2016-04-01

    Historical weather and climate data are essential for the establishment of long-term climate patterns and future projections. For South Africa, where there is a paucity of such long-term climate data, it undermines the ability to establish climate changes and variability over longer periods of the past few centuries. Consequently, analyses of climate change in the region have relied on relatively poor resolution proxy records. Yet, the recently discovered instrumental meteorological records of the Royal Astronomical Observatory in Cape Town provides South Africa's (and possibly the southern hemisphere's) longest continuous time series of daily recorded weather measurements, including temperature, rainfall, barometric pressure and wind (1835 to present). Wind specifically is a reliable indicator of dynamic atmospheric circulation and lends supporting data for understanding the Mediterranean climate of the region. This project has manually digitized, pre-processed and validated wind data from the earliest records by comparing these data with the only other known wind data for that time in the region - namely ship log data. Ship log data, recovered and digitized by the CLIWOC project, are used for statistical correlation (using wavelet query analysis) and trend analysis for the period 1843 to 1855. Both data sources indicate the same general wind climatological trends. The similarly decreasing trend in average wind velocity over the time period investigated, suggests that the data have been adequately captured and that ship log data are representative of adjoining land-based synoptic conditions. It is hoped that short term cyclic/extreme events can be extracted using a wavelet query analysis by correlating the data at various time steps. Differences in the timing of recordings and spatial scales between data sets present challenges for such a comparison. This work is part of a larger digitization project which is analysing Cape instrumental and documentary weather

  19. Introductory Biology Courses: A Framework To Support Active Learning in Large Enrollment Introductory Science Courses

    PubMed Central

    2005-01-01

    Active learning and research-oriented activities have been increasingly used in smaller, specialized science courses. Application of this type of scientific teaching to large enrollment introductory courses has been, however, a major challenge. The general microbiology lecture/laboratory course described has been designed to incorporate published active-learning methods. Three major case studies are used as platforms for active learning. Themes from case studies are integrated into lectures and laboratory experiments, and in class and online discussions and assignments. Students are stimulated to apply facts to problem-solving and to learn research skills such as data analysis, writing, and working in teams. This course is feasible only because of its organizational framework that makes use of teaching teams (made up of faculty, graduate assistants, and undergraduate assistants) and Web-based technology. Technology is a mode of communication, but also a system of course management. The relevance of this model to other biology courses led to assessment and evaluation, including an analysis of student responses to the new course, class performance, a university course evaluation, and retention of course learning. The results are indicative of an increase in student engagement in research-oriented activities and an appreciation of real-world context by students. PMID:15917873

  3. Paging tradeoffs in distributed-shared-memory multiprocessors

    SciTech Connect

    Burger, D.C.; Hyder, R.S.; Miller, B.P.; Wood, D.A.

    1994-12-31

    Massively parallel processors have begun using commodity operating systems that support demand-paged virtual memory. To evaluate the utility of virtual memory, the authors measured the behavior of seven shared memory parallel application programs on a simulated distributed-shared-memory machine. The results (1) confirm the importance of gang CPU scheduling, (2) show that a page-faulting processor should spin rather than invoke a parallel context switch, (3) show that the parallel programs frequently touch most of their data, and (4) indicate that memory, not just CPUs, must be ``gang scheduled``. Overall, the experiments demonstrate that demand paging has limited value on current parallel machines because of the applications` synchronization and memory reference patterns and the machines` high page-fault and parallel-context-switch overheads.

  4. Ranking nodes in growing networks: When PageRank fails

    NASA Astrophysics Data System (ADS)

    Mariani, Manuel Sebastian; Medo, Matúš; Zhang, Yi-Cheng

    2015-11-01

    PageRank is arguably the most popular ranking algorithm which is being applied in real systems ranging from information to biological and infrastructure networks. Despite its outstanding popularity and broad use in different areas of science, the relation between the algorithm’s efficacy and properties of the network on which it acts has not yet been fully understood. We study here PageRank’s performance on a network model supported by real data, and show that realistic temporal effects make PageRank fail in individuating the most valuable nodes for a broad range of model parameters. Results on real data are in qualitative agreement with our model-based findings. This failure of PageRank reveals that the static approach to information filtering is inappropriate for a broad class of growing systems, and suggest that time-dependent algorithms that are based on the temporal linking patterns of these systems are needed to better rank the nodes.

    2014-04-29

    A method and system for providing a memory access check on a processor including the steps of detecting accesses to a memory device including level-1 cache using a wakeup unit. The method includes invalidating level-1 cache ranges corresponding to a guard page, and configuring a plurality of wakeup address compare (WAC) registers to allow access to selected WAC registers. The method selects one of the plurality of WAC registers, and sets up a WAC register related to the guard page. The method configures the wakeup unit to interrupt on access of the selected WAC register. The method detects access of the memory device using the wakeup unit when a guard page is violated. The method generates an interrupt to the core using the wakeup unit, and determines the source of the interrupt. The method detects the activated WAC registers assigned to the violated guard page, and initiates a response.

    1989-07-01

    For a long time, automatic reading has been limited to optical character recognition. one year ago, except for one high end product, all industrial software or hardware products where limited to the reading of mono-column texts without images. This does not correspond to real life needs. In a current, company, pages which need to be transformed into electronic form are not only typewritten pages, but also complex pages from professional magazines, technical manuals, financial reports and tables, administrative documents, various directories, lists of spare parts etc... The real problem of automatic reading is to transform such complex paper pages including columns, images, drawings, titles, footnotes, legends, tables, occasionally in landscape format, into a computer text file without the help of an operator. Moreover, the problem is to perform this operation at an economical cost with limited computer resources in terms of processor and memory.

    2015-03-01

    Proteins are the most diverse and functionally active biomolecules in the living system. In order to understand their diversity and dynamic functionality, visualization in native form without altering structural and functional properties during the separation from the complex mixtures is very much essential. In the present study, a sensitive methodology for optimal visualization of unstained or untagged proteins in native poly-acrylamide gel electrophoresis (N-PAGE) has been developed where, concentration of the acrylamide and bis-acrylamide mixture, Percentage of the gel, fixing of the N-PAGE by methanol: acetic acid: water and washing of the gel in the mili-Q water has been optimized for highest sensitivity using laser induced autofluorescence. The outcome with bovine serum albumin (BSA) in PAGE was found to be highest at acrylamide and bis-acrylamide concentrations of 29.2 and 0.8 respectively in 12% N-PAGE. After the electrophoresis run, washing of the N-PAGE immediately with miliQ water for 12 times and eliminating the methanol: acetic acid: water, fixing of the N-PAGE yielded better sensitivity of visualization. Using the above methodology 25ng of BSA protein band in PAGE was clearly identified by the technique. The currently used staining techniques for the visualization of proteins are coomassie brilliant blue and silver staining, have the sensitivity of 100ng and 5ng respectively. The current methodology was found to be more sensitive as compared to coomassie staining and less sensitive compared to silver staining respectively. The added advantage of this methodology is the faster visualization of proteins without altering their structure and functional properties.

  19. Facilitating Students' Problem Solving across Multiple Representations in Introductory Mechanics

    NASA Astrophysics Data System (ADS)

    Nguyen, Dong-Hai; Gire, Elizabeth; Rebello, N. Sanjay

    2010-10-01

    Solving problems presented in multiple representations is an important skill for future physicists and engineers. However, such a task is not easy for most students taking introductory physics courses. We conducted teaching/learning interviews with 20 students in a first-semester calculus-based physics course on several topics in introductory mechanics. These interviews helped identify the common difficulties students encountered when solving physics problems posed in multiple representations as well as the hints that help students overcome those difficulties. We found that most representational difficulties arise due to the lack of students' ability to associate physics knowledge with corresponding mathematical knowledge. Based on those findings, we developed, tested and refined a set of problem-solving exercises to help students learn to solve problems in graphical and equational representations. We present our findings on students' common difficulties with graphical and equational representations, the problem-solving exercises and their impact on students' problem solving abilities.

  20. Introductory Physics Gender Gaps: Pre- and Post-Studio Transition

    2009-11-01

    Prior work has characterized the gender gaps present in college-level introductory physics courses. Such work has also shown that research-based interactive engagement techniques can reduce or eliminate these gender gaps. In this paper, we study the gender gaps (and lack thereof) in the introductory calculus-based electricity and magnetism course at the Colorado School of Mines. We present eight semesters' worth of data, totaling 2577 students, with four semesters preceding a transition to Studio physics, and four following. We examine gender gaps in course grades, DFW (D grade, fail, or withdrawal) rates, and normalized gains on the Conceptual Survey of Electricity and Magnetism (CSEM), and consider factors such as student ACT scores and grades in prior math classes. We find little or no gap in male/female course grades and DFW rates, but substantial gaps in CSEM gains that are reduced somewhat by the transition to Studio physics.

    2002-02-01

    Many introductory physics texts introduce the statistical basis for the definition of entropy in addition to the Clausius definition, ΔS=q/T. We use a model based on equally spaced energy levels to present a way that the statistical definition of entropy can be developed at the introductory level. In addition to motivating the statistical definition of entropy, we also develop statistical arguments to answer the following questions: (i) Why does a system approach a state of maximum number of microstates? (ii) What is the equilibrium distribution of particles? (iii) What is the statistical basis of temperature? (iv) What is the statistical basis for the direction of spontaneous energy transfer? Finally, a correspondence between the statistical and the classical Clausius definitions of entropy is made.

    We developed web-based modules addressing fundamental concepts of introductory biology delivered through the LON-CAPA course management system. These modules were designed and used to supplement large, lecture-based introductory biology classes. Incorporating educational principles and the strength of web-based instructional technology, choices were made about knowledge presentation, representation, and construction (W. A. Nelson, D. B. Palumbo (1992) J. Educ. Media Hypermedia 1, 287-299). Knowledge presentation focused on big and connecting ideas. Knowledge representation provided students the opportunity to interact with concepts in several ways using multiple representations. For knowledge construction, we facilitated students' active and meaningful interactions with content using interwoven high-level questions. Students' extended responses to a questionnaire indicated that these modules influenced the students learning in meaningful ways.

    The development of the HTTP protocol has been driven by the need to improve the network performance of the protocol by allowing the efficient retrieval of multiple parts of a web page without the need for multiple simultaneous TCP connections between a client and a server. We suggest that the retrieval of multiple page elements sequentially over a single TCP connection may result in a degradation of the perceived performance experienced by the user. We attempt to quantify this perceived degradation through the use of a model which combines a web retrieval simulation and an analytical model of TCP operation. Starting with the current HTTP/l.1 specification, we first suggest a client@side heuristic to improve the perceived transfer performance. We show that the perceived speed of the page retrieval can be increased without sacrificing data transfer efficiency. We then propose a new client/server extension to the HTTP/l.1 protocol to allow for the interleaving of page element retrievals. We finally address the issue of the display of advertisements on web pages, and in particular suggest a number of mechanisms which can make efficient use of IP multicast to send advertisements to a number of clients within the same network.

  9. Automatic Hidden-Web Table Interpretation by Sibling Page Comparison

    Tao, Cui; Embley, David W.

    The longstanding problem of automatic table interpretation still illudes us. Its solution would not only be an aid to table processing applications such as large volume table conversion, but would also be an aid in solving related problems such as information extraction and semi-structured data management. In this paper, we offer a conceptual modeling solution for the common special case in which so-called sibling pages are available. The sibling pages we consider are pages on the hidden web, commonly generated from underlying databases. We compare them to identify and connect nonvarying components (category labels) and varying components (data values). We tested our solution using more than 2,000 tables in source pages from three different domains—car advertisements, molecular biology, and geopolitical information. Experimental results show that the system can successfully identify sibling tables, generate structure patterns, interpret tables using the generated patterns, and automatically adjust the structure patterns, if necessary, as it processes a sequence of hidden-web pages. For these activities, the system was able to achieve an overall F-measure of 94.5%.

    Comic page image understanding aims to analyse the layout of the comic page images by detecting the storyboards and identifying the reading order automatically. It is the key technique to produce the digital comic documents suitable for reading on mobile devices. In this paper, we propose a novel comic page image understanding method based on edge segment analysis. First, we propose an efficient edge point chaining method to extract Canny edge segments (i.e., contiguous chains of Canny edge points) from the input comic page image; second, we propose a top-down scheme to detect line segments within each obtained edge segment; third, we develop a novel method to detect the storyboards by selecting the border lines and further identify the reading order of these storyboards. The proposed method is performed on a data set consisting of 2000 comic page images from ten printed comic series. The experimental results demonstrate that the proposed method achieves satisfactory results on different comics and outperforms the existing methods.

    Biology of the twenty-first century is an increasingly quantitative science. Undergraduate biology education therefore needs to provide opportunities for students to develop fluency in the tools and language of quantitative disciplines. Quantitative literacy (QL) is important for future scientists as well as for citizens, who need to interpret numeric information and data-based claims regarding nearly every aspect of daily life. To address the need for QL in biology education, we incorporated quantitative concepts throughout a semester-long introductory biology course at a large research university. Early in the course, we assessed the quantitative skills that students bring to the introductory biology classroom and found that students had difficulties in performing simple calculations, representing data graphically, and articulating data-driven arguments. In response to students' learning needs, we infused the course with quantitative concepts aligned with the existing course content and learning objectives. The effectiveness of this approach is demonstrated by significant improvement in the quality of students' graphical representations of biological data. Infusing QL in introductory biology presents challenges. Our study, however, supports the conclusion that it is feasible in the context of an existing course, consistent with the goals of college biology education, and promotes students' development of important quantitative skills.

  12. An assessment template for introductory college biological laboratory manuals

    NASA Astrophysics Data System (ADS)

    Peters, Carolyn J.

    In this study, a template was designed in an effort to resolve an instructional problem defined as the absence of adequate biology laboratory exercises in introductory college biology laboratory manuals for use in the community college setting. The problem for study was a lack of an assessment template to analyze laboratory exercises for optimum delivery of problem resolution. Past templates were analyzed for deficiencies and objectives and research questions were developed. The literature search indicated a need for more problem resolution laboratory exercises in biology. Biology instructors agree that students should engage in laboratory practice in much the same way that scientists do in the real world. They should pose questions, solve problems, investigate phenomena, test hypotheses, reinvestigate if new hypotheses arise during testing, draw conclusions, and understand basic solutions. A new design template was formulated and reviewed by five experienced community college biology instructors in Illinois. Twelve introductory laboratory exercises containing problem resolution tasks were reviewed. These specialists offered suggestions and comments about the use of the template. Several templates had been developed since the 1960s. None of these templates were for individual instructor use and many were developed for secondary texts or laboratory manuals. In this study, the deficiencies of the templates were examined in an effort to design an optimum template for individual instructor use in analyzing laboratory exercises in community college introductory biology classes.

  13. A Cosmic Distance Ladder Project for Introductory Astronomy

    2005-05-01

    I have created a six-part, semester long cosmic distance ladder project for the introductory astronomy courses at Westfield State College. Initially developed for an honors section of introductory astronomy, it has now been used in regular sections for two semesters. The project includes calibration of the size of the AU and parsec, parallax calibration of the main sequence, main sequence fitting of a star cluster, calibration of the Cepheid period-luminosity relation, calibration of the absolute magnitude of galaxies, and determination of the Hubble constant and age of the universe. Both real and simulated data are used, including several of the Project CLEA exercises produced at Gettysburg College. The average of the class results for each part is used as inputs for the next part, so the students encounter the same cumulative errors that face astronomers. Although designed around the particular needs and mechanics of the introductory astronomy classes for non-majors at WSC, this project could be adapted for use in courses at many different levels. Support from the WSC Chairs' Travel Fund is gratefully acknowledged.

    It is a long-held belief that adequate mathematics preparation is a key to success in introductory college science courses. Indeed, a number of recent studies have tested mathematics "fluency" and compared that to performance in introductory physics or chemistry courses. At the University of Colorado at Boulder, we administered a twenty-question math assessment to incoming first-year students as part of orientation registration. The intent of this tool was to provide information for advising new college students about their readiness for college-level science courses, both those for science majors and those for non-scientists. In this presentation we describe the results of the mathematics assessment for two incoming classes in the College of Arts and Sciences at CU-Boulder (about 9,000 students) and its predictive capabilities for success in introductory science courses. We also analyze student performance in these courses (i.e., course grade) with respect to ACT and/or SAT scores. We will present data on the relative success of students in college science courses both with and without prior college-level mathematics courses as well.

    2011-01-01

    Attrition of undergraduates from Biology majors is a long-standing problem. Introductory courses that fail to engage students or spark their curiosity by emphasizing the open-ended and creative nature of biological investigation and discovery could contribute to student detachment from the field. Our hypothesis was that introductory biology books devote relatively few figures to illustration of the design and interpretation of experiments or field studies, thereby de-emphasizing the scientific process. To investigate this possibility, we examined figures in six Introductory Biology textbooks published in 2008. On average, multistep scientific investigations were presented in fewer than 5% of the hundreds of figures in each book. Devoting such a small percentage of figures to the processes by which discoveries are made discourages an emphasis on scientific thinking. We suggest that by increasing significantly the illustration of scientific investigations, textbooks could support undergraduates’ early interest in biology, stimulate the development of design and analytical skills, and inspire some students to participate in investigations of their own.

    A FORTRAN 77 program is presented for calculating with the given accuracy eigenvalues, eigenfunctions and their first derivatives with respect to the parameter of the parametric self-adjoined Sturm-Liouville problem with the parametric third type boundary conditions on the finite interval. The program calculates also potential matrix elements - integrals of the eigenfunctions multiplied by their first derivatives with respect to the parameter. Eigenvalues and matrix elements computed by the ODPEVP program can be used for solving the bound state and multi-channel scattering problems for a system of the coupled second-order ordinary differential equations with the help of the KANTBP programs [O. Chuluunbaatar, A.A. Gusev, A.G. Abrashkevich, A. Amaya-Tapia, M.S. Kaschiev, S.Y. Larsen, S.I. Vinitsky, Comput. Phys. Commun. 177 (2007) 649-675; O. Chuluunbaatar, A.A. Gusev, S.I. Vinitsky, A.G. Abrashkevich, Comput. Phys. Commun. 179 (2008) 685-693]. As a test desk, the program is applied to the calculation of the potential matrix elements for an integrable 2D-model of three identical particles on a line with pair zero-range potentials, a 3D-model of a hydrogen atom in a homogeneous magnetic field and a hydrogen atom on a three-dimensional sphere.

    Membrane page composers were made and were evaluated in a simulated holographic optical memory system. Calculated and experimentally determined electromechanical and optical characteristics of the circular membrane light valves used on the arrays are shown to be in close agreement. Several operating prototypes of 8 x 8 and 16 x 16 elements were produced. Measurements were made of switching time, optical contrast, and dynamic storage time of many cells on the devices. Digital patterns were stored in the arrays. The performance required of the page composer as a component of an optical memory system is considered. The fabrication techniques used can be easily extended to larger arrays.

  19. Identification of Malicious Web Pages by Inductive Learning

    Malicious web pages are an increasing threat to current computer systems in recent years. Traditional anti-virus techniques focus typically on detection of the static signatures of Malware and are ineffective against these new threats because they cannot deal with zero-day attacks. In this paper, a novel classification method for detecting malicious web pages is presented. This method is generalization and specialization of attack pattern based on inductive learning, which can be used for updating and expanding knowledge database. The attack pattern is established from an example and generalized by inductive learning, which can be used to detect unknown attacks whose behavior is similar to the example.

  20. Creating a Facebook Page for the Seismological Society of America

    2009-12-01

    In August, 2009 I created a Facebook “fan” page for the Seismological Society of America. We had been exploring cost-effective options for providing forums for two-way communication for some months. We knew that a number of larger technical societies had invested significant sums of money to create customized social networking sites but that a small society would need to use existing low-cost software options. The first thing I discovered when I began to set up the fan page was that an unofficial SSA Facebook group already existed, established by Steven J. Gibbons, a member in Norway. Steven had done an excellent job of posting material about SSA. Partly because of the existing group, the official SSA fan page gained fans rapidly. We began by posting information about our own activities and then added links to activities in the broader geoscience community. While much of this material also appeared on our website and in our publication, Seismological Research Letters (SRL), the tone on the FB page is different. It is less formal with more emphasis on photos and links to other sites, including our own. Fans who are active on FB see the posts as part of their social network and do not need to take the initiative to go to the SSA site. Although the goal was to provide a forum for two-way communication, our initial experience was that people were clearly reading the page but not contributing content. This appears to be case with fan pages of sister geoscience societies. FB offers some demographic information to fan site administrators. In an initial review of the demographics it appeared that fans were younger than the overall demographics of the Society. It appeared that a few of the fans are not members or even scientists. Open questions are: what content will be most useful to fans? How will the existence of the page benefit the membership as a whole? Will the page ultimately encourage two-way communication as hoped? Web 2.0 is generating a series of new

  1. Using Portfolios to Engage Introductory Geoscience Students in Their Subject and to Develop Learning Skills.

    2008-12-01

    It is often difficult to deal with wide-ranging, exciting geoscience topics at introductory level when the background geoscience knowledge of the incoming students is limited. This means that new students can often be confronted by self-contained, subject-based topics (e.g. introductory mineralogy) and fail to see where the bigger pictures may be. Another issue, partly arising from massification and thus increasing diversity of student cohorts but also to changes in UK school education goals, is the realisation that incoming students have difficulties combining lecture note taking, reading and general organisation of paper-based materials into a learning package that can help them write structured essays. They need help with the transfer from school to university education. Two years ago, a curriculum review provided the opportunity to develop a new module that could address these issues. The module deals with current topics. Students attend a series of 8 lectures given by 8 different faculty staff covering topics like The Origin of the Moon, Earthquake Prediction, Mass Extinctions, Snowball Earth, and Geohazards spread over the introductory year. Each lecturer uses whatever delivery style they want (PowerPoint, chalk and talk), but the lecture must be an illustration of the scientific method dealing with evidence, models and uncertainty, and must direct students towards a range of associated reading. The students develop a portfolio with a section for each lecture topic. Each section contains their notes, annotated copies of the reading and a one page (A4) summary of the main points of the topic, derived from both the notes and reading. The students also develop a glossary of geological terms. In addition, the students must attend 6 extra talks given by guest speakers at either the student society meetings or the departmental seminar series. Assessment is by the portfolio (40%) and a final essay paper (60%). The portfolio is collected in at the end of the first

  2. A narrative study of selected introductory college biology students' struggles to gain an understanding of scale and measurement

    2000-10-01

    Case studies, developed with criteria from Yin's Case Study Research: Design and Methods (1994), probed single mental constructs of four introductory college biology students who were recent high school graduates. Data sources included autobiographical essays, interviews, coconstructed concept maps (Wandersee & Abrams, 1993), a videotape questionnaire, and graphics. A multisensory microscopy experiment provided the setting for the construction of shared meanings by the participants. Concept maps were used then to explore the existing cognitive framework of the participants. This research affirmed the value of supporting graphic organizers for understanding science (Good & Berger, 1998; Hyerle, 1996; Trowbridge & Wandersee, 1998). Ausubelian cognitive learning theory (Ausubel, Novak, and Hanesian, 1978) was the theoretical foundation for this research. The heuristic device of concept mapping was used as a method to aid the student in externalizing and understanding the development and integration of relevant concepts. Ausubel (1968), Novak and Gowin (1984) recognize the positive results of knowledge construction from laboratory experiences. Expanding the student's immediate knowledge of microscopy with instruction by the researcher helped students connect scale relationships with microscopy. Results of this study suggest (a) that there are anticipatable and addressable gaps in their knowledge of size, scale, measurement, and micrometry that introductory college biology students bring to the science laboratory, and (b) that these gaps and misunderstandings will otherwise impede their learning from microscopy-based laboratory experiences and frustrate their ability to measure and to grasp the relative size of microstructures and microorganisms meaningfully. Results also suggest that, the MicroMeasure(TM) grid system in particular may offer a new and more effective way to help students learn to interpret the magnification powers used in presenting the objects pictured
