    2013-05-01

    Science educators, historians of science and their students often share a curiosity about historical instruments as a tangible link between past and present practices in the sciences. We less often integrate instruments into our research and pedagogy, considering artefact study as the domain of museum specialists. We argue here that scholars and teachers new to material culture can readily use artefacts to reveal rich and complex networks of narratives. We illustrate this point by describing our own lay encounter with an artefact turned over for our analysis during a week-long workshop at the Canada Science and Technology Museum. The text explains how elements as disparate as the military appearance of the instrument, the crest stamped on its body, the manipulation of its telescopes, or a luggage tag revealed the object's scientific and political significance in different national contexts. In this way, the presence of the instrument in the classroom vividly conveyed the nature of geophysics as a field practice and an international science, and illuminated relationships between pure and applied science for early twentieth century geologists. We conclude that artefact study can be an unexpectedly powerful and accessible tool in the study of science, making visible the connections between past and present, laboratory and field, texts and instruments.

  15. Development of perceived instrumentality for mathematics, reading and science curricula

    NASA Astrophysics Data System (ADS)

    Garcia, Steve L.

    Perceptions of instrumentality (PI) are the connections one sees between a current activity and a future goal. With high PI, one is motivated to persist with quality effort because the current activity, even when difficult, is perceived as aligned with, and progress toward, the goal. Conversely, with low PI, one is motivated to relinquish effort in pursuit of other, more meaningful goals. In view of the alarming dropout rates in this country, it appears that PI research has much to offer in understanding students' motivations to stay in school and hence to become employed in their field of choice. Because academic achievement motivation can be affected by gender and ethnicity, particularly for specific components of the curriculum, and because curricular content varies across grade levels and school settings, this line of research offers significant potential for understanding and improving student outcomes. This research examined the development of PI among suburban 6th, 8th, 10th and 12th graders from a school district in the southwestern United States. Twelve hundred students completed a one-time paper and pencil survey measuring the perceived instrumentality of mathematics, literacy and science courses in terms of the students' occupational choices. MANOVA was used to determine factors that may affect students' overall PI and individual subject PI. Grade, gender, ethnicity, occupational choice, expectancy and value were the independent variables. A school setting variable was examined for effects on 12th graders. For the 8th through 12th grade sample, significant main effects were observed for grade, gender, minority status, occupational choice and expectancy on PI. Results show that PI is highest in the 6 th grade. Males reported higher Math PI than females. Females reported higher Reading PI and Science PI than males. Minority students reported lower overall PI and Science PI than non-minority students. Students who aspire to professional careers report the highest PI; and students who expect to achieve their occupational choice score higher than those who do not. Among 12th graders, significant two-way interaction effects on PI were observed between school type and gender; school type and occupational value; and, occupational expectancy and value.

    2015-01-01

    Transcranial direct current stimulation (tDCS) is a neuromodulatory technique that offers promise as an investigative method for understanding complex cognitive operations such as reading. This study explores the ability of a single session of tDCS to modulate reading efficiency and phonological processing performance within a group of healthy adults. Half the group received anodal or cathodal stimulation, on two separate days, of the left temporo-parietal junction while the other half received anodal or cathodal stimulation of the right homologue area. Pre- and post-stimulation assessment of reading efficiency and phonological processing was carried out. A larger pre-post difference in reading efficiency was found for participants who received right anodal stimulation compared to participants who received left anodal stimulation. Further, there was a significant post-stimulation increase in phonological processing speed following right hemisphere anodal stimulation. Implications for models of reading and reading impairment are discussed. PMID:25852513

    Hossain, M.A.; Carpenter, D.R.

    1989-05-01

    The Wilford Hall USAF Medical Center Central Processing Section (WHMC/SGLP) uses ethylene oxide (EtO) as a primary sterilizing agent. Because of their concern about the health effects of EtO, SGLP has searched for a continuous-monitoring EtO system. In their search, they found two units (AMSCO's Envirogard III and Baseline Industries, Inc.'s Model 5500 Gas Analyzer). The objective of this evaluation was to conduct a field study to compare the performances of the two direct-reading continuous EtO monitors against the Occupational Safety and Health Administration's (OSHA) acceptable charcoal-tube sampling method. In addition, the 3M EtO passive monitor sampling method was compared with the charcoal-tube method and direct-reading instrumental method as well. Neither the Baseline Industries, Inc. nor the AMSCO continuous monitors corresponded to OSHA acceptable charcoal tube method of air sampling. Both instruments reported EtO concentrations much higher than those detected by the charcoal tubes. There is no way of knowing which method, the direct-reading continuous monitor or the charcoal tube/passive monitor, is more correct. However, the OSHA standard for EtO is based on measuring EtO by the charcoal tube method.

  6. Measurement of proton momentum distributions using a direct geometry instrument

    NASA Astrophysics Data System (ADS)

    Senesi, R.; Kolesnikov, A. I.; Andreani, C.

    2014-12-01

    We report the results of inelastic neutron scattering measurements on bulk water and ice using the direct geometry SEQUOIA chopper spectrometer at the Spallation Neutron Source (USA), with incident energy Ei= 6 eV. In this set up the measurements allow to access the Deep Inelastic Neutron Scattering regime. The scattering is centred at the proton recoil energy given by the impulse approximation, and the shape of the recoil peak conveys information on the proton momentum distribution in the system. The comparison with the performance of inverse geometry instruments, such as VESUVIO at the ISIS source (UK), shows that complementary information can be accessed by the use of direct and inverse geometry instruments. Analysis of the neutron Compton profiles shows that the proton kinetic energy in ice at 271 K is larger than in room temperature liquid water, in agreement with previous measurements on VESUVIO.

  10. Up or down? Reading direction influences vertical counting direction in the horizontal plane – a cross-cultural comparison

    PubMed Central

    Göbel, Silke M.

    2015-01-01

    Most adults and children in cultures where reading text progresses from left to right also count objects from the left to the right side of space. The reverse is found in cultures with a right-to-left reading direction. The current set of experiments investigated whether vertical counting in the horizontal plane is also influenced by reading direction. Participants were either from a left-to-right reading culture (UK) or from a mixed (left-to-right and top-to-bottom) reading culture (Hong Kong). In Experiment 1, native English-speaking children and adults and native Cantonese-speaking children and adults performed three object counting tasks. Objects were presented flat on a table in a horizontal, vertical, and square display. Independent of culture, the horizontal array was mostly counted from left to right. While the majority of English-speaking children counted the vertical display from bottom to top, the majority of the Cantonese-speaking children as well as both Cantonese- and English-speaking adults counted the vertical display from top to bottom. This pattern was replicated in the counting pattern for squares: all groups except the English-speaking children started counting with the top left coin. In Experiment 2, Cantonese-speaking adults counted a square array of objects after they read a text presented to them either in left-to-right or in top-to-bottom reading direction. Most Cantonese-speaking adults started counting the array by moving horizontally from left to right. However, significantly more Cantonese-speaking adults started counting with a top-to-bottom movement after reading the text presented in a top-to-bottom reading direction than in a left-to-right reading direction. Our results show clearly that vertical counting in the horizontal plane is influenced by longstanding as well as more recent experience of reading direction. PMID:25852583

  11. Optimization of Orchestral Layouts Based on Instrument Directivity Patterns

    NASA Astrophysics Data System (ADS)

    Stroud, Nathan Paul

    The experience of hearing an exceptional symphony orchestra perform in an excel- lent concert hall can be profound and moving, causing a level of excitement not often reached for listeners. Romantic period style orchestral music, recognized for validating the use of intense emotion for aesthetic pleasure, was the last significant development in the history of the orchestra. In an age where orchestral popularity is waning, the possibil- ity of evolving the orchestral sound in our modern era exists through the combination of our current understanding of instrument directivity patterns and their interaction with architectural acoustics. With the aid of wave field synthesis (WFS), newly proposed variations on orchestral layouts are tested virtually using a 64-channel WFS array. Each layout is objectively and subjectively compared for determination of which layout could optimize the sound of the orchestra and revitalize the excitement of the performance.

  14. Aerosol Monitoring during Carbon Nanofiber Production: Mobile Direct-Reading Sampling

    PubMed Central

    Evans, Douglas E.; Ku, Bon Ki; Birch, M. Eileen; Dunn, Kevin H.

    2010-01-01

    Detailed investigations were conducted at a facility that manufactures and processes carbon nanofibers (CNFs). Presented research summarizes the direct-reading monitoring aspects of the study. A mobile aerosol sampling platform, equipped with an aerosol instrument array, was used to characterize emissions at different locations within the facility. Particle number, respirable mass, active surface area, and photoelectric response were monitored with a condensation particle counter (CPC), a photometer, a diffusion charger, and a photoelectric aerosol sensor, respectively. CO and CO2 were additionally monitored. Combined simultaneous monitoring of these metrics can be utilized to determine source and relative contribution of airborne particles (CNFs and others) within a workplace. Elevated particle number concentrations, up to 1.15 × 106 cm?3, were found within the facility but were not due to CNFs. Ultrafine particle emissions, released during thermal treatment of CNFs, were primarily responsible. In contrast, transient increases in respirable particle mass concentration, with a maximum of 1.1 mg m?3, were due to CNF release through uncontrolled transfer and bagging. Of the applied metrics, our findings suggest that particle mass was probably the most useful and practical metric for monitoring CNF emissions in this facility. Through chemical means, CNFs may be selectively distinguished from other workplace contaminants (Birch et al., in preparation), and for direct-reading monitoring applications, the photometer was found to provide a reasonable estimate of respirable CNF mass concentration. Particle size distribution measurements were conducted with an electrical low-pressure impactor and a fast particle size spectrometer. Results suggest that the dominant CNF mode by particle number lies between 200 and 250 nm for both aerodynamic and mobility equivalent diameters. Significant emissions of CO were also evident in this facility. Exposure control recommendations were described for processes as required. PMID:20447936

  16. Assessment of personal direct-reading dust monitors for the measurement of airborne inhalable dust.

    PubMed

    Thorpe, Andrew

    2007-01-01

    The performances of five portable direct-reading dust monitors were investigated in a wind tunnel for a range of industrial dusts and three sizes of aluminium oxide test dust to mainly determine their suitability for measuring the inhalable fraction of airborne dust in workplaces. The instruments tested were Split 2 (SKC Ltd), Sidepak (TSI Inc.), Dataram (Thermo Electron Ltd), PDS-2 (Sibata Scientific Technology Ltd) and the Respicon TM (Hund Ltd). The instruments' responses were compared with reference dust samplers. These were the IOM sampler for the inhalable fraction and the Casella cyclone sampler for the respirable fraction. All instruments are predominantly responsive to and are designed to measure particles in the respirable size range, although two of the instruments, the Split 2 and Respicon TM, are claimed to be capable of measuring inhalable-sized particles. For the purpose of the tests, major modifications to an existing wind tunnel dust injection system were made to facilitate the generation of uniform concentrations of large inhalable-sized dust particles at low air velocities. Each monitor greatly underestimated the measurement of inhalable concentration for all the dusts tested, although the linearity was good over a wide range of concentrations for any particular size distribution of dust. However, their calibration factors, defined as the ratio of reference inhalable concentration to monitor concentration, were especially sensitive to changes in particle size as the response of the instruments decreased rapidly with increasing particle size. The monitors generally overestimated the measurement of respirable dust concentration by up to a factor of about 2, apart from the PDS-2, which underestimated it by a factor of up to 3. There was, however, a great deal more scatter in the reference respirable concentration measurements owing to the collection of small dust samples. Therefore, monitor linearity and effects of monitor response to changes in particle size could not be accurately investigated for the respirable fraction. The sampling head of the Split 2 monitor incorporates an IOM inlet and filter to gravimetrically collect the inhalable fraction of airborne dust. This can give a concurrent reference measure of inhalable airborne dust concentration. However, poor sealing within the sampling head resulted in some of the sampled dust not reaching the backup filter. This resulted in the Split 2 underestimating the reference inhalable dust concentration, which meant that it could not be accurately used as a calibration standard. Communications with the manufacturers have since revealed that the sampling head has recently been redesigned in order to improve the seal and eliminate leakage. The Respicon sampler gravimetrically underestimated the inhalable dust concentration, and did so increasingly as the particle size increased. PMID:16799158

  18. Development of a new instrument for direct skin friction measurements

    NASA Technical Reports Server (NTRS)

    Vakili, A. D.; Wu, J. M.

    1986-01-01

    A device developed for the direct measurement of wall shear stress generated by flows is described. Simple and symmetric in design with optional small moving mass and no internal friction, the features employed in the design eliminate most of the difficulties associated with the traditional floating element balances. The device is basically small and can be made in various sizes. Vibration problems associated with the floating element skin friction balances were found to be minimized due to the design symmetry and optional damping provided. The design eliminates or reduces the errors associated with conventional floating element devices: such as errors due to gaps, pressure gradient, acceleration, heat transfer, and temperature change. The instrument is equipped with various sensing systems and the output signal is a linear function of the wall shear stress. Dynamic measurements could be made in a limited range and measurements in liquids could be performed readily. Measurement made in the three different tunnels show excellent agreement with data obtained by the floating element devices and other techniques.

  19. Dealing with the size-of-source effect in the calibration of direct-reading radiation thermometer

    The majority of general-purpose low-temperature handheld radiation thermometers are severely affected by the size-of-source effect (SSE). Calibration of these instruments is pointless unless the SSE is accounted for in the calibration process. Traditional SSE measurement techniques, however, are costly and time consuming, and because the instruments are direct-reading in temperature, traditional SSE results are not easily interpretable, particularly by the general user. This paper describes a simplified method for measuring the SSE, suitable for second-tier calibration laboratories and requiring no additional equipment, and proposes a means of reporting SSE results on a calibration certificate that should be easily understood by the non-specialist user.

    Advance directives are written or oral statements that are intended to govern healthcare decision-making for their authors, for both positive and negative decisions, should they lose decisional capacity in the future. In a Europe which is facing an ageing population, advance directives play an increasing role to (help) formulate the wishes from elderly patient once they start losing the capacity to decide independently. Advance directives should not only be used as a formulation of the patients' previously made decision, but can also be used as guidelines to better understand the previous expressed wishes of the patient. If the advance directive is formulated in too vague form, the healthcare proxy and/or the healthcare trustee can help the physician interpret the directive. This broader approach towards advance directives is reflected in the case-law of the European Court of Human Rights, as well as on the European legislative level. PMID:22558655

    This engineering note documents the Dzero Superconducting Solenoid Platinum RTD, Carbon Glass RTD, and Helium level gage instrumentation values upon receipt at Fermilab. This note is concerned with the internal instrumentation, the external instrumentation can easily be repaired if any problems arise. The Solenoid was Purchased from Toshiba and shipped from the Kehin Works in Japan. The Solenoid was received at Dzero May 12, 1997. The Solenoid was shipped in three large components. They are the Solenoid, Control Dewar, and Chimney. There are 2 main instrumentation port areas where all the internal instrumentation is available to the outside world. These 2 places are the top of the Control Dewar and the North end of the Solenoid. These two instrumentation feedthrough area's have Cyocera hermetic feedthrough port connectors welded into place. The Cyocera connector can and does mate with the Burndy Bantom cable end connector of the same pin/socket number. Since the Hermetic feedthrough and cable connector are different manufacturers, the pin layout pattern is not the same. The Toshiba drawings show both manufacturers pin numbers. The Dzero engineering notes show only the Burndy pin numbers.

    2014-09-01

    A growing amount of evidence confirms the influence of reading and writing habits on visuospatial processing, although this phenomenon has been so far testified mainly as a lateralized shift of a single behavioral sign (e.g., line bisection), with lack of proof from pure right-to-left readers. The present study contributed to this issue by analyzing multiple attentional and motor indexes in monolingual Italian (i.e., reading from left-to-right), and monolingual (i.e., reading from right-to-left) and bilingual Israeli (i.e., reading from right-to-left in Hebrew but also from left-to-right in English) participants' visuospatial performance. Subjects were administered a computerized standard star cancellation task and a modified version in which English letters and words were replaced by Hebrew ones. Tasks were presented on a graphics tablet, allowing recording of both chronometric and spatial parameters (i.e., measured in (x, y) vector coordinates). Results showed that reading direction modulated the on-line visuomotor performance (i.e., left-to-right vs. right-to-left shifts) from the beginning (i.e., first mark) to the end of the task (i.e., spatial distribution of omissions and subjective epicenter). Additionally, the spatial bias observed in a computerized line bisection task was also related to the participants' habitual reading direction. Overall, the results favor the proposal of an Interactive Account of visuospatial asymmetries, according to which both cultural factors, such as the directional scanning associated with language processing, and biological factors, such as hemispheric specialization, modulate visuospatial processing. Results are discussed in light of recent behavioral and neuroanatomical findings. PMID:24968311

Participants were 153 ethnically-diverse children (84 male, 69 female) from general education classes evaluated in the winter and spring of their first-grade academic year. Children completed standardized measures of reading achievement involving decoding and fluency along with an anxiety rating scale. Hierarchical linear regression analyses revealed that separation anxiety symptoms were negatively predicted by fluency performance and harm avoidance symptoms were positively predicted by decoding performance. Fluency performance was positively predicted by harm avoidance and total anxiety (for girls only) symptoms, while decoding was not predicted by any anxiety subscale. PMID:21822734

    Chinese offers a unique tool for testing the effects of word form on language processing during reading. The processes of letter-mediated grapheme-to-phoneme translation and phonemic assembly (assembled phonology) critical for reading and spelling in any alphabetic orthography are largely absent when reading nonalphabetic Chinese characters. In contrast, script-to-sound translation based on the script as a whole (addressed phonology) is absent when reading the Chinese alphabetic sound symbols known as pinyin, for which the script-to-sound translation is based exclusively on assembled phonology. The present study aims to contrast patterns of brain activity associated with the different cognitive mechanisms needed for reading the two scripts. fMRI was used with a block design involving a phonological and lexical task in which subjects were asked to decide whether visually presented, paired Chinese characters or pinyin "sounded like" a word. Results demonstrate that reading Chinese characters and pinyin activate a common brain network including the inferior frontal, middle, and inferior temporal gyri, the inferior and superior parietal lobules, and the extrastriate areas. However, some regions show relatively greater activation for either pinyin or Chinese reading. Reading pinyin led to a greater activation in the inferior parietal cortex bilaterally, the precuneus, and the anterior middle temporal gyrus. In contrast, activation in the left fusiform gyrus, the bilateral cuneus, the posterior middle temporal, the right inferior frontal gyrus, and the bilateral superior frontal gyrus were greater for nonalphabetic Chinese reading. We conclude that both alphabetic and nonalphabetic scripts activate a common brain network for reading. Overall, there are no differences in terms of hemispheric specialization between alphabetic and nonalphabetic scripts. However, differences in language surface form appear to determine relative activation in other regions. Some of these regions (e.g., the inferior parietal cortex for pinyin and fusiform gyrus for Chinese characters) are candidate regions for specialized processes associated with reading via predominantly assembled (pinyin) or addressed (Chinese character) procedures.

    Paper Title: Balance Calibration – A method for assigning a direct-reading uncertainty to an electronic balance. Intended Audience: Those who calibrate or use electronic balances. Abstract: As a calibration facility, we provide on-site (at the customer’s location) calibrations of electronic balances for customers within our company. In our experience, most of our customers are not using their balance as a comparator, but simply putting an unknown quantity on the balance and reading the displayed mass value. Manufacturer’s specifications for balances typically include specifications such as readability, repeatability, linearity, and sensitivity temperature drift, but what does this all mean when the balance user simply reads the displayed mass value and accepts the reading as the true value? This paper discusses a method for assigning a direct-reading uncertainty to a balance based upon the observed calibration data and the environment where the balance is being used. The method requires input from the customer regarding the environment where the balance is used and encourages discussion with the customer regarding sources of uncertainty and possible means for improvement; the calibration process becomes an educational opportunity for the balance user as well as calibration personnel. This paper will cover the uncertainty analysis applied to the calibration weights used for the field calibration of balances; the uncertainty is calculated over the range of environmental conditions typically encountered in the field and the resulting range of air density. The temperature stability in the area of the balance is discussed with the customer and the temperature range over which the balance calibration is valid is decided upon; the decision is based upon the uncertainty needs of the customer and the desired rigor in monitoring by the customer. Once the environmental limitations are decided, the calibration is performed and the measurement data is entered into a custom spreadsheet. The spreadsheet uses measurement results, along with the manufacturer’s specifications, to assign a direct-read measurement uncertainty to the balance. The fact that the assigned uncertainty is a best-case uncertainty is discussed with the customer; the assigned uncertainty contains no allowance for contributions associated with the unknown weighing sample, such as density, static charges, magnetism, etc. The attendee will learn uncertainty considerations associated with balance calibrations along with one method for assigning an uncertainty to a balance used for non-comparison measurements.

    The development of high-throughput sequencing technologies has advanced our understanding of cancer. However, characterizing somatic structural variants in tumor genomes is still challenging because current strategies depend on the initial alignment of reads to a reference genome. Here, we describe SMUFIN (somatic mutation finder), a single program that directly compares sequence reads from normal and tumor genomes to accurately identify and characterize a range of somatic sequence variation, from single-nucleotide variants (SNV) to large structural variants at base pair resolution. Performance tests on modeled tumor genomes showed average sensitivity of 92% and 74% for SNVs and structural variants, with specificities of 95% and 91%, respectively. Analyses of aggressive forms of solid and hematological tumors revealed that SMUFIN identifies breakpoints associated with chromothripsis and chromoplexy with high specificity. SMUFIN provides an integrated solution for the accurate, fast and comprehensive characterization of somatic sequence variation in cancer. PMID:25344728

    Prior studies on reasoning tasks have shown lateral spatial biases on mental model construction, which converge with known spatial biases in the mental representation of number, time, and events. The latter have been shown to be related to habitual reading and writing direction. The present study bridges and extends both research strands by looking at the processes of mental model construction in language comprehension and examining how they are influenced by reading and writing direction. Sentences like "the table is between the lamp and the TV" were auditorily presented to groups of mono- and bidirectional readers in languages with left-to-right or right-to-left scripts, and participants were asked to draw the described scene. There was a clear preference for deploying the lateral objects in the direction marked by the script of the input language and some hints of a much smaller effect of the degree of practice with the script. These lateral biases occurred in the context of universal strategies for working memory management. PMID:23307481

    Although neurologically normal individuals often exhibit leftward biases of perception and attention, known as pseudoneglect, factors such as lighting, spatial location and native reading direction have been found to modulate these biases. To investigate lighting and spatial biases in left-to-right and right-to-left readers search times were measured in a target finding task where lighting and target locations were manipulated. Target search times under upper-left lighting were significantly shorter than lower-left, upper-right and lower-right lighting among left-to-right readers. Right-to-left readers did not display the same leftward bias, even displaying significantly shorter search times under upper-right lighting than those of left-to-right readers. Significantly shorter search times for targets located in the upper-left quadrant (compared to other quadrants) were observed for left-to-right readers, while search times for upper-right located targets were significantly shorter for right-to-left readers compared to those of left-to-right readers. Participant scan times of stimuli divided into equal quadrants were monitored by an eye-tracking camera. Both groups displayed greater scan times in upper quadrants. These findings suggest that native reading direction modulates spatial and light perception biases resulting in weaker leftward, or a lack of lateral biases among right-to-left readers.

    This study was conducted to determine if engineered nanoparticles are released into the air when nanocomposite parts are shredded for recycling. Test plaques made from polypropylene resin reinforced with either montmorillonite nanoclay or talc and from the same resin with no reinforcing material were shredded by a granulator inside a test apparatus. As the plaques were shredded, an ultrafine condensation particle counter; a diffusion charger; a photometer; an electrical mobility analyzer; and an optical particle counter measured number, lung-deposited surface area, and mass concentrations and size distributions by number in real-time. Overall, the particle levels produced were both stable and lower than found in some occupational environments. Although the lowest particle concentrations were observed when the talc-filled plaques were shredded, fewer nanoparticles were generated from the nanocomposite plaques than when the plain resin plaques were shredded. For example, the average particle number concentrations measured using the ultrafine condensation particle counter were 1300 particles/cm(3) for the talc-reinforced resin, 4280 particles/cm(3) for the nanoclay-reinforced resin, and 12,600 particles/cm(3) for the plain resin. Similarly, the average alveolar-deposited particle surface area concentrations measured using the diffusion charger were 4.0 ?m(2)/cm(3) for the talc-reinforced resin, 8.5 ?m(2)/cm(3) for the nanoclay-reinforced resin, and 26 ?m(2)/cm(3) for the plain resin. For all three materials, count median diameters were near 10 nm during tests, which is smaller than should be found from the reinforcing materials. These findings suggest that recycling of nanoclay-reinforced plastics does not have a strong potential to generate more airborne nanoparticles than recycling of conventional plastics. PMID:22168254

    Participants’ eye movements were monitored in an experiment that manipulated the frequency of target words (high vs. low) as well as their availability for parafoveal processing during fixations on the pre-target word (valid vs. invalid preview). The influence of the word-frequency by preview validity manipulation on the distributions of first fixation duration was examined by using ex-Gaussian fitting as well as a novel survival analysis technique which provided precise estimates of the timing of the first discernible influence of word frequency on first fixation duration. Using this technique, we found a significant influence of word frequency on fixation duration in normal reading (valid preview) as early as 145 ms from the start of fixation. We also demonstrated an equally rapid non-lexical influence on first fixation duration as a function of initial landing position (location) on target words. The time-course of frequency effects, but not location effects was strongly influenced by preview validity, demonstrating the crucial role of parafoveal processing in enabling direct lexical control of reading fixation times. Implications for models of eye-movement control are discussed. PMID:22542804

  13. Enhanced discrimination of boreal forest covers with directional reflectances from the airborne polarization and directionality of Earth reflectances (POLDER) instrument

    NASA Astrophysics Data System (ADS)

    Bicheron, P.; Leroy, M.; Hautecoeur, O.; BréOn, F. M.

    1997-12-01

    During the Boreal Ecosystem-Atmosphere Study (BOREAS), directional and spectral reflectance measurements were acquired from May to July 1994 with the polarization and directionality of Earth reflectances (POLDER) instrument on board a NASA C-130 aircraft. The instrument has a wide field-of-view optics, a two-dimensional CCD array, and a rotating wheel carrying filters in the visible and near infrared. Measurements were obtained (1) over coniferous forests at the young and old jack pine and old black spruce sites, (2) over a deciduous forest at the old aspen site, and (3) over a fen at the fen site. A prominent hot spot feature was apparent at each site, with an additional strong peak in the specular direction for the fen site. Strong variations of the bidirectional reflectance distribution function (BRDF) with sun zenith angle were observed. For a constant sun zenith angle, the variation of the BRDF of conifer stands between May and July was relatively weak. A key objective of this paper is to quantify the improvement of discrimination of various forest covers when remotely sensed directional signatures are added to the more conventional spectral signatures. The experimental protocol consisted of the following steps. First, 150 pixels pertaining to five different classes of forest covers were selected on land cover maps available in the BOREAS Information System (BORIS) data base. Second, the BRDF measurements acquired by POLDER at each pixel were adjusted against a three-parameter semiempirical BRDF model and processed to retrieve the reflectance seen in three different viewing directions. Third, the results of supervised classifications were compared on all selected pixels, using as input, either the reflectances in only one direction (this simulates the case of conventional spectral signatures), or reflectances acquired in three directions (this simulates the case of spectral + directional signatures). The results showed that when only one spectral band was used, the proportion of correctly classified pixels increased from 36-59% with one viewing direction to 64-84% with three viewing directions. When three spectral bands were considered, this proportion improved from 72-87% to 83-97%. These results demonstrate that the account of directional information enhances the ability to discriminate forest covers by remotesensing.

    This study compared the Biomic automated well reader results to the MicroScan WalkAway results for reading MicroScan antimicrobial susceptibility and identification panels at four different sites. Routine fresh clinical isolates and quality control (QC) organisms were tested at each study site. A total of 46,176 MicroScan panel drug-organism combinations were read. The Biomic category agreement for 3,117 Gram-negative bacteria was 98.4%, with 1.4% minor and 0.2% major discrepancies. The Biomic category agreement for 5,233 Gram-positive bacteria was 98.7%, with 0.9% minor, 0.3% major, and 0.1% very major errors. Essential agreement, defined as Biomic results that were within ±1 2-fold dilution of the MicroScan results, was 99.3% for Gram-negative bacteria and 98.3% for Gram-positive bacteria. Biomic reading of MicroScan identification panels provided an overall agreement (first- and second-choice organism match) of 99.5% with 846 Gram-negative isolates and 99.5% with 430 Gram-positive isolates. These results suggest that the Biomic automated reader can provide accurate reading of MicroScan panels and has the capability of a visual panel read for manual adjustment of results. PMID:23486713

Such observations will provide additional information for 3D modeling of the Earth and for understanding earthquakes and other underground explosions. In this paper, we describe the design of an instrument capable of measuring the rotational motions associated with the seismic oscillations of the Earth, including the lowest frequency normal mode at nu approximately 3.7 x 10(-4) Hz. The instrument consists of a torsion balance with a natural frequency of nu(0) approximately 1.6 x 10(-4) Hz, which is observed by an autocollimating optical lever of high angular resolution and dynamic range. Thermal noise limits the sensitivity of the apparatus to amplitudes of approximately 1.5 x 10(-9) rad at the lowest frequency normal mode and the sensitivity improves as nu(-3/2) with increasing frequency. Further improvements in sensitivity by about two orders of magnitude may be achieved by operating the balance at cryogenic temperatures. Alternatively, the instrument can be made more robust with a reduced sensitivity by increasing nu(0) to approximately 10(-2) Hz. This instrument thus complements the ongoing effort by Igel and others to study rotational motions using ring laser gyroscopes and constitutes a positive response to the clarion call for developments in rotation seismology by Igel, Lee, and Todorovska [H. Igel, W.H.K. Lee and M.I. Todorovska, AGU Fall Meeting 2006, Rotational Seismology Sessions: S22A,S23B, Inauguration of the International Working Group on Rotational Seismology (IWGoRS)].

    The rotations around the vertical axis associated with the normal mode oscillations of the Earth and those induced by the seismic and other disturbances have been very difficult to observe directly. Such observations will provide additional information for 3D modeling of the Earth and for understanding earthquakes and other underground explosions. In this paper, we describe the design of an instrument capable of measuring the rotational motions associated with the seismic oscillations of the Earth, including the lowest frequency normal mode at ? ? 3.7 × 10?4 Hz. The instrument consists of a torsion balance with a natural frequency of ?0 ? 1.6 × 10?4 Hz, which is observed by an autocollimating optical lever of high angular resolution and dynamic range. Thermal noise limits the sensitivity of the apparatus to amplitudes of ? 1.5 × 10?9 rad at the lowest frequency normal mode and the sensitivity improves as ??3/2 with increasing frequency. Further improvements in sensitivity by about two orders of magnitude may be achieved by operating the balance at cryogenic temperatures. Alternatively, the instrument can be made more robust with a reduced sensitivity by increasing ?0 to ?10?2 Hz. This instrument thus complements the ongoing effort by Igel and others to study rotational motions using ring laser gyroscopes and constitutes a positive response to the clarion call for developments in rotation seismology by Igel, Lee, and Todorovska [H.

    Naphthalene has been identified by the National Research Council as a serious health hazard for personnel working with jet fuels and oil-based sealants containing naphthalene. We are developing a family of miniature, self-contained, direct reading personal exposure monitors (PEMs) to detect, differentiate, quantify, and log naphthalene and other volatile organic compounds (VOCs) in the breathing zone of the wearer or in the hands of an industrial hygienist with limits of detection in the low parts per billion (ppb) range. The VOC Dosimeter (VOCDos) described here is a PEM that provides real-time detection and data logging of exposure as well as accumulated dose, with alarms addressing long term and immediate exposure limits. We will describe the sensor, which employs optical methods with a unique excitation source and rapidly refreshable vapor concentrator. This paper addresses the rapidly increasing awareness of the health risks of inhaling jet fuel vapors by Department of Defense (DOD) personnel engaged in or around jet fueling operations. Naphthalene is a one to three percent component of the 5 billion gallons of jet fuels used annually by DOD. Naphthalene is also a component of many other petroleum products such as asphalt and other oil-based sealants. The DOD is the single largest user of petroleum fuels in the United States (20% of all petroleum fuel used). The VOCDos wearable sensor provides real-time detection and data logging of exposure as well as accumulated dose. We will describe the sensor, which employs endogenous fluorescence from VOCs accumulated on a unique, rapidly refreshable, patent-pending concentrator, excited by a unique deep ultraviolet excitation source.

    The SPICA coronagraph instrument (SCI) provides high-contrast imaging and moderate resolution (R giant planets down to one Jupiter mass around nearby young (1 Gyr) stars and two Jupiter masses around nearby old (5 Gyr) stars. SCI also allows to characterizing those planets of less than 1 Gyr by spectroscopic observations to reveal the nature of planetary formation and evolution. Focusing on the high sensitivity and high contrast at wavelengths longer than 10 \\mu m, we show that SCI also allows us to directly image icy giant planets like Uranus and Neptune as well as gas giant planets around nearby early-type stars. In this paper, we compare the capabilities of SCI and the JWST coronagraphs and also discuss a new approach to answering questions concerning the formation and evolution of planetary systems through planet detection with SCI.

    Introduction. Single incision laparoscopic cholecystectomy (SILC) has become accepted as an alternative to conventional multiport cholecystectomy. However, SILC is still limited in applicability in low resource centres due to the expense associated with specialized access platforms, curved instruments, and flexible scopes. Presentation of Case. We present three cases where a modified SILC technique was used with conventional instruments and no working ports. The evolution of this technique is described. Discussion. In order to contain cost, we used conventional instruments and three transfascial ports placed in an umbilical incision, but we noted significant instrument clashes that originated at the port platforms. Therefore, we modified our technique by omitting ports for the working instruments. The technique allowed us to exchange instruments as necessary, maximized ergonomics, and prevented collisions from the bulky port platforms. Finally, the puncture left by the instrument alone did not require fascial closure at the termination of the procedure. Conclusion. The direct transfascial puncture using conventional laparoscopic instruments without working ports is a feasible option that minimizes cost and increases ergonomics. PMID:25349766

    Coffey, Christopher; LeBouf, Ryan; Lee, Larry; Slaven, James; Martin, Stephen

    2012-01-01

    The performance of three MIRAN SapphIRe Portable Infrared Ambient Air Analyzers and three Century Portable Toxic Vapor Analyzers equipped with photoionization (PID) and flame ionization (FID) detectors was compared with charcoal tube sampling. Relationships were investigated using two different calibration methods at four cyclohexane concentrations, three temperatures, and four relative humidities. For the first method, the TVA monitors were calibrated with a single concentration of methane for the FID, and isobutylene for the PID. The SapphIRe monitors were zeroed and the monitor's manufacturer-supplied library was used. For the second method, a five-point cyclohexane calibration curve was created for each monitor. Comparison of the monitor results of each calibration method (pooled data) indicated a significant difference between methods (t-test, p < 0.001), The SapphIRe group had results closer to the charcoal tubes with the second calibration method, while the PID and FID monitor groups performed better using the first calibration method. The PID monitor group's performance was affected only at the 90% relative humidity (RH) condition. Using the first method, the monitor readings were compared with the charcoal tube average using mixed linear model analyses of variance (ANOVAs) and regression. The ANOVA results showed there was a statistically significant difference among readings from all monitor types (p <0.0001). The regression results demonstrated that the SapphIRe (r˛ = 0.97) and FID (r˛ = 0.92) monitor groups correlated well with the charcoal tubes. The PID monitor group had a similar correlation when 90% RH was excluded (r˛ = 0.94) but had a weaker correlation when it was included (r˛ = 0.58). The operator should take care when using these monitors at high concentrations and the PID monitors at high humidities, consider the variability between units of the same monitor, and conduct performance verification of the monitor being used.

    2007-01-01

    Since the independent invention of DNA sequencing by Sanger and by Gilbert 30 years ago, it has grown from a small scale technique capable of reading several kilobase-pair of sequence per day into today's multibillion dollar industry. This growth has spurred the development of new sequencing technologies that do not involve either electrophoresis or Sanger sequencing chemistries. Sequencing by Synthesis (SBS) involves multiple parallel micro-sequencing addition events occurring on a surface, where data from each round is detected by imaging. New High Throughput Technologies for DNA Sequencing and Genomics is the second volume in the Perspectives in Bioanalysis series, which looks at the electroanalytical chemistry of nucleic acids and proteins, development of electrochemical sensors and their application in biomedicine and in the new fields of genomics and proteomics. The authors have expertly formatted the information for a wide variety of readers, including new developments that will inspire students and young scientists to create new tools for science and medicine in the 21st century. Reviews of complementary developments in Sanger and SBS sequencing chemistries, capillary electrophoresis and microdevice integration, MS sequencing and applications set the framework for the book.

    The Subaru Coronagraphic Extreme AO (SCExAO) instrument consists of a high performance Phase Induced Amplitude Apodisation (PIAA) coronagraph combined with an extreme Adaptive Optics (AO) system operating in the near-infrared (H band). The extreme AO system driven by the 2000 element deformable mirror will allow for Strehl ratios>90% to be achieved in the H-band when it goes closed loop. This makes the SCExAO instrument a powerful platform for high contrast imaging down to angular separations of the order of 1 lambda/D and an ideal testbed for exploring coronagraphic techniques for ELTs. In this paper we report on the recent progress in regards to the development of the instrument, which includes the addition of a visible bench that makes use of the light at shorter wavelengths not currently utilized by SCExAO and closing the loop on the tip/tilt wavefront sensor. We will also discuss several exciting guest instruments which will expand the capabilities of SCExAO over the next few years; namely CHARIS which is a integral field spectrograph as well as VAMPIRES, a visible aperture masking experiment based on polarimetric analysis of circumstellar disks. In addition we will elucidate the unique role extreme AO systems will play in enabling high precision radial velocity spectroscopy for the detection of small companions.

    We report on strain analysis by nano-beam electron diffraction with a spatial resolution of 0.5nm and a strain precision in the 4-7·10-4 range. Series of up to 160000 CBED patterns have been acquired in STEM mode with a semi-convergence angle of the incident probe of 2.6mrad, which enhances the spatial resolution by a factor of 5 compared to nearly parallel illumination. Firstly, we summarise 3 different algorithms to detect CBED disc positions accurately: selective edge detection and circle fitting, radial gradient maximisation and cross-correlation with masks. They yield equivalent strain profiles in growth direction for a stack of 5 InxGa1-xNyAs1-y/GaAs layers with tensile and compressive strain. Secondly, we use a direct electron read-out pnCCD detector with ultrafast readout hardware and a quantum efficiency close to 1 both to show that the same strain profiles are obtained at 200 times higher readout rates of 1kHz and to enhance strain precision to 3.5·10-4 by recording the weak 008 disc.

  3. The validity and reliability of the self-directed learning instrument (SDLI) in mainland Chinese nursing students

    PubMed Central

    2014-01-01

    Background Self-directed learning is crucial to the professional development of nursing students, and which enables them to expand the knowledge and enhance the quality of their practice. A validated self-directed learning instrument is important not only in assessing the individual’s self-directed learning level, but also in evaluating the effectiveness of teaching or learning methods. The aim of this study is to evaluate the validity and reliability of the SDLI in mainland Chinese nursing students. Methods A cross-sectional design with convenience sampling was used to recruit participants from three nursing schools. The mainland Chinese version of SDLI was tested with respect to validity and reliability in 1,499 nursing students, and another 30 nursing students were invited to evaluate the test-retest reliability of the scale in 7?days interval. Results Explorary factor analysis identified a four-factor structure, accounting for 56.101% of the total variance. The confirmatory factor analysis showed a good overall fit of this four-factor model. Convergent validity was supported by the highly positive Pearson’s correlation between SDLI score and SRSSDL score (r?=?.876, p?=?.000). Cronbach’s alpha for internal consistency of overall scale was .916, and 4 dimensions were between .755-.825.The test-retest reliability of overall scale was .850, and 4 dimensions were between .708-.821. The intraclass correlation coefficient (ICC) of overall scale was .916, and 4 dimensions were .822-.889. Conclusions This study indicates that the SDLI is a valid and reliable instrument for assessing self-directed learning in mainland Chinese nursing students. Nurse educators could use such knowledge to develop their roles and plan to support nursing students in becoming self-directed learners and lifelong learner. PMID:24885557

  7. POLVSM (Polarized Volume Scattering Meter) instrument: an innovative device to measure the directional and polarized scattering properties of hydrosols.

    PubMed

    Chami, Malik; Thirouard, Alexandre; Harmel, Tristan

    2014-10-20

    An innovative instrument dedicated to the multispectral measurements of the directional and polarized scattering properties of the hydrosols, so-called POLVSM, is described. The instrument could be used onboard a ship, as a benchtop instrument, or at laboratory. The originality of the POLVSM concept relies on the use of a double periscopic optical system whose role is (i) to separate the plane containing the light source from the scattering plane containing the sample and the receiver and (ii) to prevent from any specularly reflected light within the sample chamber. As a result, a wide range of scattering angle, namely from 1° to 179°, is covered by the detector. Another originality of the instrument is to measure the Mueller scattering matrix elements, including the degree of polarization. A relevant calibration procedure, which could be of great interest as well for other instruments, is proposed to convert the raw data into physical units. The relative uncertainty in POLVSM data was determined at ± 4.3%. The analysis of measurements of the volume scattering function and degree of polarization performed under controlled conditions for samples dominated either by inorganic hydrosols or phytoplankton monospecific species showed a good consistency with literature, thus confirming the good performance of the POLVSM device. Comparisons of POLVSM data with theoretical calculations showed that Mie theory could reproduce efficiently the measurements of the VSF and degree of polarization for the case of inorganic hydrosols sample, despite the likely non sphericity of these particles as revealed by one of the element of the Mueller matrix. Our results suggested as well that a sophisticated modeling of the heterogeneous internal structure of living cells, or at least, the use of layered sphere models, is needed to correctly predict the directional and polarized effects of phytoplankton on the oceanic radiation. The relevance of performing angularly resolved measurements of the Mueller scattering elements to gain understanding on the mechanisms processes involved in the scattering of light by marine particles, which has important implications for ocean color remote sensing studies, is demonstrated.

    Global measurement of tropospheric winds is a key measurement for understanding atmospheric dynamics and improving numerical weather prediction. Global wind profiles remain a high priority for the operational weather community and also for a variety of research applications including studies of the global hydrologic cycle and transport studies of aerosols and trace species. In addition to space based winds, a high altitude airborne system flown on UAV or other advanced platforms would be of great interest for studying mesoscale dynamics and hurricanes. The Tropospheric Wind Lidar Technology Experiment (TWiLiTE) project was selected in 2005 by the NASA Earth Sun Technology Office as part of the Instrument Incubator Program. TWiLiTE will leverage significant research and development investments in key technologies made in the past several years. The primary focus will be on integrating these sub-systems into a complete molecular direct detection Doppler wind lidar system designed for autonomous operation on a high altitude aircraft, such as the NASA WB57, so that the nadir viewing lidar will be able to profile winds through the full troposphere. TWiLiTE is a collaboration involving scientists and technologists from NASA Goddard, NOAA ESRL, Utah State University Space Dynamics Lab and industry partners Michigan Aerospace Corporation and Sigma Space Corporation. NASA Goddard and it's partners have been at the forefront in the development of key lidar technologies (lasers, telescopes, scanning systems, detectors and receivers) required to enable spaceborne global wind lidar measurement. The TWiLiTE integrated airborne Doppler lidar instrument will be the first demonstration of a airborne scanning direct detection Doppler lidar and will serve as a critical milestone on the path to a fixture spaceborne tropospheric wind system. The completed system will have the capability to profile winds in clear air from the aircraft altitude of 18 h to the surface with 250 m vertical resolution and less than 2 meters per second velocity accuracy. The instrument design, technologies and predicted performance will be presented.

    Direct force measuring transducer acts as an arterial tonometer, gives a direct readout to instrumentation, and is unaffected by ambient noise. It uses a semiconductor strain gage which is deflected by pressure pulses in the artery. The deflection changes the resistance of the gage and alters the voltage reading on the associated instrumentation.

  16. A Direct Method for Calculating Instrument Noise Levels in Side-by-Side Seismometer Evaluations

    USGS Publications Warehouse

    Holcomb, L. Gary

    1989-01-01

    INTRODUCTION The subject of determining the inherent system noise levels present in modem broadband closed loop seismic sensors has been an evolving topic ever since closed loop systems became available. Closed loop systems are unique in that the system noise can not be determined via a blocked mass test as in older conventional open loop seismic sensors. Instead, most investigators have resorted to performing measurements on two or more systems operating in close proximity to one another and to analyzing the outputs of these systems with respect to one another to ascertain their relative noise levels. The analysis of side-by-side relative performance is inherently dependent on the accuracy of the mathematical modeling of the test configuration. This report presents a direct approach to extracting the system noise levels of two linear systems with a common coherent input signal. The mathematical solution to the problem is incredibly simple; however the practical application of the method encounters some difficulties. Examples of expected accuracies are presented as derived by simulating real systems performance using computer generated random noise. In addition, examples of the performance of the method when applied to real experimental test data are shown.

  17. Instrumental Direction-dependent Effects in Wide-field Wide-band Interferometric Imaging

    2014-04-01

    Many next generation radio telescopes, some now in operation, offer significant improvement in the sensitivity and angular resolution compared to the telescopes operated in the past decades. This improvement in sensitivity is achieved with the use of wide-band receivers and larger collecting area. The effects of wide instantaneous fractional bandwidths that classical calibration and imaging algorithms ignore, lead to errors higher than the sensitivity that these new telescopes offer. Examples, relevant for some of the telescopes already in operation include the effects of time and frequency variant primary beams, frequency dependence of the emission from the sky and antenna pointing errors. The effects of wide fractional bandwidth and ionospheric phase screen limit the imaging performance below ~1 GHz. Additionally, significant variations in the shape of the wide-band primary beams (PB) for aperture array telescopes leads to errors of similar magnitude. Corrections for these effects increases the required computing power by many orders of magnitude. Furthermore, both wide fractional bandwidths and larger collecting area lead to many orders of magnitude increase in the data volume also, putting severe constraints on the run-time performance of the algorithms for calibration and imaging. In this talk, I will review the state-of-the-art algorithms for wide-field wide-band imaging and the run-time costs of the different approaches for correction of various direction-dependent effects and discuss the computational challenges in thermal noise-limited wide-field imaging with current and future radio telescopes.

    Sequence-specific DNA binding by transcription factors is central to gene expression regulation. While a number of methods for characterizing DNA-protein interactions are currently available1-6, none have demonstrated both quantitative measurement of affinity and high throughput. To address this challenge, we developed HiTS-FLIP, a technique that couples high-throughput sequencing with direct visualization of in vitro binding to provide quantitative protein-DNA binding affinity measurements at unprecedented depth. HiTS-FLIP analysis of GCN4, the master regulator of the yeast amino acid starvation response7, yielded 440 million binding measurements, enabling determination of context-averaged dissociation constants for all 12mer sequences having submicromolar affinity. These data revealed complex interdependency between motif positions, yielded improved discrimination of in vivo GCN4 binding sites and regulatory targets relative to previous models, and identified sets of genes with distinct GCN4 affinity levels which had distinct functions and expression kinetics. This approach promises to deepen understanding of the interactions that drive transcription. PMID:21706015

    2005-01-01

    For delicate operations conducted using surgical robot systems, surgeons need to receive information regarding the contact forces on the tips of surgical instruments. For the detection of this contact force, one of the authors previously proposed a new method, called the overcoat method, in which the instrument is supported by sensors positioned on the overcoat pipe. This method requires cancellation of the acceleration forces of the instrument/holder attached to the overcoat sensor. In the present report, the authors attempt to use acceleration sensors to obtain the acceleration forces of the instrument/holder. The new cancellation method provides a force-detection accuracy of approximately 0.05-0.1 N for a dynamic response range of up to approximately 20 Hz, compared to approximately 1 Hz, which was achieved by using acceleration forces based on the theoretical robot motion.

    2009-05-01

    We present advances in instrumentation for fast, direct, high-sensitivity in situ measurement of formaldehyde and alpha-dicarbonyls. Glyoxal, the smallest dicarbonyl, is a molecule of emerging importance. It is a tracer of the oxidative chemistry of volatile organic compounds (VOCs) and has been implicated in secondary organic aerosol (SOA) formation. We have developed a laser-induced phosphorescence (LIP) instrument for measurement of ambient glyoxal, taking advantage of the unusually high intersystem crossing yield of alpha-dicarbonyls. This is the first instrument for atmospheric field measurements based on LIP. Measurement of the slow (30 microsecond) phosphorescence offers the advantage of temporal separation from laser scatter and fluorescence, obviating the need for filters to eliminate particulate matter. The instrument has been characterized in two field campaigns and the precision during the PROPHET 2008 field campaign was 2 pptv/min. We present an extension of instrumental capabilities to measuring glyoxal fluxes via eddy-correlation, and of the LIP method to measuring methylglyoxal. The Madison LIP instrument can thus provide alpha-dicarbonyl datasets essential to insight into the oxidative chemistry of VOCs and SOA formation. We have also developed a laser-induced fluorescence (LIF) based instrument for fast, high-sensitivity measurements of formaldehyde with a precision as high as 20 pptv/min. We present characterization of the instrument during the PROPHET 2008 field campaign. Since then, we have replaced the Ti:Sapphire laser with a novel pulsed fiber laser, which has considerable advantages in many important aspects, such as size and power requirements, and it offers an opportunity to significantly advance laser based instrumentation in the UV- Vis range. Fiber-coupling also eliminates problems with optics contamination. Finally, the laser can be tuned rapidly, as required for formaldehyde flux measurements via eddy correlation. The entire instrument (excluding the pump) requires roughly 3'x3'x2' and is ideally suited for ground-based and aircraft measurements.

    This grant was intended to be used for the purchase of high quality laboratory and data analysis instrumentation for the pursuit of space plasma physics research. Two of the first purchases were a 6250 BPI magnetic tape drive and a large, fast disk drive. These improved the satellite data analysis capability greatly and reduced the system backup time. With the big disk drive it became possible to dump entire magnetic tapes to disk for faster, more efficient processing. Several microcomputers improve both personnel computing as well as general connectivity within the group and on campus in general. Other microcomputers function in the laboratory setting by acting as hosts for several instrument interfaces for communication with satellite and balloon payloads as well as laboratory VLF signal processing equipment. Perhaps the single most expensive item purchased was an analog tape drive for reading and writing 16 in. analog magnetic tapes. This analog tape drive is used for the direct processing of FM and directly recorded telemetry data from the balloon and rocket payloads.

    The Upper Atmosphere Research Satellite (UARS) was launched by Space Shuttle STS-48 on 12 September 1991 and included a direct Doppler experiment, the High Resolution Doppler Imager, HRDI. Ten years later, the TIMED Doppler Interferometer, TIDI, joined HRDI in direct neutral wind observations of the mesosphere and lower thermosphere (MLT). The removal of instrumental artifacts from the raw spectra, complicated by the loss of good attitude knowledge for HRDI and unexpected signal contamination for TIDI has matured to a level where excellent agreement exists for common volume measurements between them. The two experiments were able to perform overlapping measurements of tidal and planetary wave fields for three years permitting unprecedented clarity in the description of the cyclical behaviour of the MLT. The exhaust plume left in the wake of the launch of STS-107 (16 January 2003) provided a stringent test between TIDI, HRDI, and independent imagery, the latter of which showed rapid transport across the equator to the Antarctic. Though TIDI and HRDI observed the atmosphere at the plume’s location at different local solar times, all correlative observations supported the hypothesis indicated by once-a-day images of the plume - rapid southern transport over thousands of kilometers. A simple spectral analysis of simultaneous observations of the neutral winds by HRDI and TIDI indicates that a classical two-day wave (longitudinal wavenumber = 3) exists in the southern hemisphere during the ~80-hour transit time coinciding with the transport of the plume exhaust from launch to the Antarctic. A least-squares fit of the wave in the meridional wind indicates maximum amplitude in the MLT of ~80 m/s southwards. Other shuttle launches have also been accompanied by evidence that implies rapid transport of exhaust plumes to Arctic latitudes. This paper will summarize correlative HRDI and/or TIDI wind observations of these events and associated spectral analysis of the meridional wind in the MLT. There is no question that TIDI and HRDI confirm the rapid implied motion suggested by space-borne imagery of shuttle exhaust plumes. Empirical and first-principle physical models of MLT dynamics fall short in describing the amplitude and long life of strong meridional flow. The consistency between TIDI, HRDI, and independent observations of rapid plume transport indicate that our understanding of MLT dynamics is far from complete.

  20. A direct correlation among indoor Rn, soil gas Rn and geology in the Reading Prong near Boyertown, Pennsylvania

    USGS Publications Warehouse

    Reimer, G.M.; Gundersen, L.C.S.

    1989-01-01

    We feel that this study suggests a relationship among geology, soil gas Rn and the potential for indoor Rn accumulation in this portion of the Reading Prong. There are deviations from a perfect correlation but these are related to inhomogeneities in the geologic environment and perhaps variations in construction techniques of homes in the area. This study also demonstrates that several analyses in a small area may be necessary to adequately determine the Rn distribution for a particular geologic unit. That scale would be determined by the complexity of the local geology. Where no discrete source of elevated Rn supply is found for dwellings having a significant Rn accumulation, the implication is that overall gross permeability may be sufficient to supply Rn from a larger volume of soil and rock.

    2004-11-01

    Aluminium smelter potrooms are unique in that workplace exposures to hydrogen fluoride (HF), sulfur dioxide (SO2), and particulate matter occur simultaneously for some tasks. The peak exposures to these contaminants are of increasing interest in discovering the etiology of respiratory health effects. While a variety of direct-reading instruments are available for sulfur dioxide and particulate matter, only a few exist for hydrogen fluoride. The sensors in these HF instruments have a cross-sensitivity to sulfur dioxide making it difficult to monitor HF in an environment that also contains SO2. To overcome this problem, we assessed the simultaneous use of two electrochemical instruments: one with a SO2 sensor that does not respond to HF and the second with a hydrogen fluoride sensor that responds to both HF and SO2 in a 1 : 1 ratio, termed 'total acid gas'. The difference in the response between the two instruments should indicate the HF concentration: [HF + SO2] minus SO2 equals HF. The performance characteristics of this sampling train were evaluated in the laboratory through the generation of both HF and SO2 with permeation tubes. The response and recovery times for the SO2 only instrument were acceptable (6 and 15 s, respectively), but the "total acid gas" instrument exhibited both slow response and slow recovery approaching three and six min. The association between the traditional integrated filter sampling method and the direct-reading instrument for SO2 is 0.80 (Spearman's rho). The use of the digital filter strengthens the association between the HF direct-reading instrument and the integrated samples from 0.41 to 0.68. PMID:15536509

This includes authentication data such as user names and key fingerprints, interactive session data such as keystrokes and responses, and information about noninteractive sessions such as commands executed and files transferred. Historically, this data has been inaccessible with traditional network monitoring techniques, but with a modification to the SSH daemon, this data can be passed directly to intrusion detection systems for analysis. The instrumented version of SSH is now running on all NERSC production systems. This paper describes the project, details about how SSH was instrumented, and the initial results of putting this in production.

    Many resources are available to elementary teachers who wish to support science learning with literature. Unfortunately, somewhere between middle school and high school, the emphasis on using literature to teach science content--particularly the exercise of reading aloud--has all but disappeared. However, the practice of reading aloud is helpful because most students have higher listening comprehension than reading comprehension (Trelease 2006)--low-reading level students, English language learners, and auditory learners in particular, tend to understand what they hear better than what they read. This article provides suggestions for including the practice of reading aloud in the high school science classroom.

    Interrupted reading is a close reading technique that consists of dividing a passage of text into short chunks and pausing the reading after each section in order for the student to consider possible responses. This type of reading helps students connect with the text by requiring that they summarize, look for devices, make predictions, etc., as they are reading. This technique helps students to build confidence as they are forced to slow down and notice detail, and it is a tool to help build analysis and commentary skills.

  11. Mappability and read length

    PubMed Central

    Li, Wentian; Freudenberg, Jan

    2014-01-01

    Power-law distributions are the main functional form for the distribution of repeat size and repeat copy number in the human genome. When the genome is broken into fragments for sequencing, the limited size of fragments and reads may prevent an unique alignment of repeat sequences to the reference sequence. Repeats in the human genome can be as long as 104 bases, or 105 ? 106 bases when allowing for mismatches between repeat units. Sequence reads from these regions are therefore unmappable when the read length is in the range of 103 bases. With a read length of 1000 bases, slightly more than 1% of the assembled genome, and slightly less than 1% of the 1 kb reads, are unmappable, excluding the unassembled portion of the human genome (8% in GRCh37/hg19). The slow decay (long tail) of the power-law function implies a diminishing return in converting unmappable regions/reads to become mappable with the increase of the read length, with the understanding that increasing read length will always move toward the direction of 100% mappability.

  13. Novel instrumentation for direct measurements of site-specific isotopic nitrogen and isotopic oxygen in ambient nitrous oxide

    The stable isotope composition of atmosphere trace gases provides information of their origin and fate that cannot be determined from their mole fraction measurements alone. Biological source and loss processes, like bacterial production of N2O, are typically accompanied by isotopic selectivity associated with the kinetics of bond formation and destruction. Due to the relatively low N2O concentration in ambient air, of the three major biologically mediated greenhouse gases (CO2, CH4 and N2O), the understanding of N2O isotopic budget lags behind the other gases. We report on the development of novel instrumentation for real-time measurements of site-specific isotopic nitrogen and of isotopic oxygen (?15Na, ?15Nb, ?15N, ?18O) and mole fraction [N2O] of nitrous oxide over a wide range of mixing ratios. This novel technology, which employs cavity enhanced absorption and a mid-infrared tunable quantum cascade laser and does not require any cryogenic components, has been developed for in situ simultaneous measurements of the mole fractions of main isotopomers - 14N14N16O, 15N14N16O, 14N15N16O and 14N14N18O, which leads to the nitrogen-isotope ratio (?15N) and the 15N site-specific enrichment. A precision of better than 1 per mil may be achieved in ambient air (with 320 ppb N2O) in less than 100 seconds measurement time. For higher mole fractions, which may be obtained using preconcentration, better precision (approaching 0.1 per mil) may be achieved. Further details on the operation and performance of the instrument will be presented.

  15. Reading Reflections

    NSDL National Science Digital Library

    Karl Wirth

    Reading reflections are designed to encourage students to complete readings before coming to class, to reflect more deeply on the content of the reading, to make personal meaning from the meaning, and to develop their metacognitive skills for lifelong learning. The reflections consist of three questions: (1) What is the main point of the reading?, (2) What information did you find surprising? Why?, and (3) What did you find confusing? Why? Students submit short responses to two of three questions prior to coming to class. Metacognitive components of the activity Reading reflections address many elements of metacognition, including knowledge, control, and reflection. Reading reflections are designed to help students develop knowledge about themselves as learners, learning tasks (reading), prior knowledge, content, self-monitoring, self-assessment, and reflection. Metacognitive goals The primary goals of this activity are to help students develop their skills of self-assessment, and to reflect more deeply on the content of their reading assignments. Reflective thinking is an essential element of expert learners, so this activity helps students develop skills as intentional learners for lifelong learning. Assessing students' metacognition Reading reflections (n = 35 in a typical semester) count for approximately 10% of the course grade. I do not grade these reflections, but give students credit if they are turned in on time (before class) and if they clearly demonstrate significant reflection.

  3. The observatories and instruments of Tycho Brahe

    NASA Astrophysics Data System (ADS)

    Wolfschmidt, Gudrun

    Tycho Brahe (1546-1601) was the most important observational astronomer until the invention of the telescope in 1608. By construction new instruments and devising new observing methods, Tycho succeeded in significantly increasing measurement accuracy: He increased the size of his instruments (e.g. a large wooden quadrant of diameter 5.4 m and a mural quadrant); he used metal and masonry rather than wood; he modified construction techniques to achieve greater stability; to provide shelter from the wind, his instruments were in subterranean nooks; his instruments were permanently and solidly mounted; for better angular readings, he developed new subdivisions and diopters (Tycho used transversals to obtain the greatest possible angular resolution readings. His instrumental sights (diopters) were specially designed to minimize errors); he carefully analysed all the errors (Tycho's aim was to reduce thethe uncertainty to less than one minute of arc); he used fundamental stars for the first time; he preferred measuring equatorial coordinates directly instead of using the zodiacal system, i.e. using the equatorial armillary sphere instead of the zodiacal armillary sphere; he tried a new measuring method with clocks and his mural quadrant (1582) for determining the right ascension; he took atmospheric refraction into account. Most of his high-accuracy instruments have been distroyed. Only two sextants, made by Jost Bürgi and Erasmus Habermel around 1600, still exist in the Narodny Technicky Muzeum (NTM) [National Technical Museum] in Prague. A model of the wooden quadrant is in the old observatory in Copenhagen, in the round tower. But we have good descriptions of the instruments (half circles of 2.3 m radius, quadrants up to 2 m radius including the mural quadrant, sextants up to 1.6 m, armillary spheres of 1.5 m radius and the great equatorial armillary sphere of 2.7 m, triquetrum and celestial globe of 1.5 m) in Tycho's book Astronomiae instauratae mechanica (Wandesburgi 1598, Nuremberg 1602). One of Tycho's instruments in original size was reconstructed in Oldenburg University and in the Steno Museum in Aarhus, Denmark. In Munich, in the Deutsches Museum's permanent astronomy exhibition (opened in 1992), the Uraniborg observatory and its instruments are shown at a scale of 1:10. A similar but larger model (scale 1:5) from the workshop of the Deutsches Museum was given to the Technical Museum in Malmř, Sweden. Tycho's later observatory Stjerneborg can be seen as a reconstruction on the island Hven (Ven/Sweden) with the original foundations for the instruments.

    A proof-of-concept of the use of a fully digital radiofrequency (RF) electronics for the design of dedicated Nuclear Magnetic Resonance (NMR) systems at low-field (0.1 T) is presented. This digital electronics is based on the use of three key elements: a Direct Digital Synthesizer (DDS) for pulse generation, a Software Defined Radio (SDR) for a digital receiving of NMR signals and a Digital Signal Processor (DSP) for system control and for the generation of the gradient signals (pulse programmer). The SDR includes a direct analog-to-digital conversion and a Digital Down Conversion (digital quadrature demodulation, decimation filtering, processing gain…). The various aspects of the concept and of the realization are addressed with some details. These include both hardware design and software considerations. One of the underlying ideas is to enable such NMR systems to “enjoy” from existing advanced technology that have been realized in other research areas, especially in telecommunication domain. Another goal is to make these systems easy to build and replicate so as to help research groups in realizing dedicated NMR desktops for a large palette of new applications. We also would like to give readers an idea of the current trends in this field. The performances of the developed electronics are discussed throughout the paper. First FID (Free Induction Decay) signals are also presented. Some development perspectives of our work in the area of low-field NMR/MRI will be finally addressed. PMID:24287540

    2013-01-01

    This article presents and technically describes a new field spectro-goniometer system for the ground-based characterization of the surface reflectance anisotropy under natural illumination conditions developed at the Alfred Wegener Institute (AWI). The spectro-goniometer consists of a Manual Transportable Instrument platform for ground-based Spectro-directional observations (ManTIS), and a hyperspectral sensor system. The presented measurement strategy shows that the AWI ManTIS field spectro-goniometer can deliver high quality hemispherical conical reflectance factor (HCRF) measurements with a pointing accuracy of ±6 cm within the constant observation center. The sampling of a ManTIS hemisphere (up to 30° viewing zenith, 360° viewing azimuth) needs approx. 18 min. The developed data processing chain in combination with the software used for the semi-automatic control provides a reliable method to reduce temporal effects during the measurements. The presented visualization and analysis approaches of the HCRF data of an Arctic low growing vegetation showcase prove the high quality of spectro-goniometer measurements. The patented low-cost and lightweight ManTIS instrument platform can be customized for various research needs and is available for purchase.

    2002-01-01

    The general objectives of this project were to improve understanding of the directional emittance properties of land surfaces in the thermal infrared (TIR) region of the electro-magnetic spectrum. To accomplish these objectives our research emphasized a combination of theoretical model development and empirical studies designed to improve land surface temperature (LST) retrievals from space-borne remote sensing instruments. Following the proposal, the main tasks for this project were to: (1) Participate in field campaigns; (2) Acquire and process field, aircraft, and ancillary data; (3) Develop and refine models of LST emission; (4) Develop algorithms for LST retrieval; and (5) Explore LST retrieval methods for use in energy balance models. In general all of these objectives were addressed, and for the most part achieved. The main results from this project are described in the publications arising from this effort. We summarize our efforts related to each of the objectives.

    2013-01-01

    A simple sample pretreatment device was developed employing extractions across supported liquid membranes (SLMs) and in-line coupling to a commercial CE instrument. The device consisted of two polypropylene conical units interspaced with a polypropylene planar SLM, which were impregnated with 1-ethyl-2-nitrobenzene. The two units and the SLM were pressed against each other, donor unit was filled with 40 ?L of an untreated body fluid and acceptor unit with 40 ?L of DI water. The device was then placed into conventional CE vial fitted with a soft spring, which was depressed during injection into CE capillary and ensured that the SLM was not ruptured. Position of separation capillary injection end and high-voltage electrode in the CE instrument was optimized in order to ensure efficient injection of pretreated body fluids. The device can be easily assembled/disassembled and SLMs can be replaced after each extraction thus minimizing sample carry-over, avoiding tedious SLM regeneration, and reducing total pretreatment time and costs. The pretreatment device was examined by direct injection of human urine and serum spiked with nortriptyline, haloperidol, and loperamide. The basic drugs were diffusionaly transported across the SLM within 10 min and were injected into the separation capillary directly from the SLM surface in the acceptor unit, whereas matrix components were retained by the SLM. The in-line SLM-CE method showed good repeatability of peak areas (3.8-11.0%) and migration times (below 1.4%), linear relationship (r(2) = 0.990-0.999), and low LODs (12-100 ?g/L). PMID:23161384

  11. Direct determination of Hg in polymers by solid sampling-graphite furnace atomic absorption spectrometry. A comparison of the performance of line source and continuum source instrumentation

    NASA Astrophysics Data System (ADS)

    Resano, M.; Briceńo, J.; Belarra, M. A.

    2009-06-01

    This work explores the potential of solid sampling-graphite furnace atomic absorption spectrometry (SS-GFAAS) for the fast and direct determination of Hg in polymers. Eight certified reference materials with different composition (polyethylene-PE-, polystyrene-PS-, poly vinyl chloride-PVC- and acrylonitrile butadiene styrene-ABS-) were selected for the study, covering a wide Hg content range (from 20 to 1100 ?g g - 1 ). The difficulties found in achieving a selective atomization of the analyte from these samples were partially mitigated by the maintenance of the Ar flow during the atomization step, leading to an improved signal-to-background ratio. Even then, when a line source (LS) GFAAS instrument was employed for analysis, it was only possible to develop truly accurate procedures relying on the use of aqueous standards for calibration for PE and PVC samples, and different atomization conditions (1200 °C and 1300 °C, respectively) were needed for the two types of samples. The use of high-resolution continuum source (HR-CS) GFAAS instrumentation permitted to improve this situation significantly thanks to its higher potential for the correction of high and fast changing background. With such an instrument, satisfactory results could be obtained for all the samples under study using the same atomization conditions (1200 °C) and aqueous standard solutions for calibration. Additionally, the HR-CS GFAAS technique presented a lower limit of detection (0.6 ?g g - 1 for CS and 2.2 ?g g - 1 for LS), a broader linear range (10 to 320 Hg ng for CS, and 20 to 200 ng for LS), and a somewhat improved sensitivity (approximately 0.0030 s ng - 1 for CS using the three central pixels for quantification, and approximately 0.0025 s ng - 1 for LS). Overall, the use of HR-CS GFAAS permits obtaining significant advantages for the determination of this complex analyte in plastics, such as straightforward calibration with aqueous standards, a high sample throughput (15 min per sample), sufficient precision (4-9% RSD), a suitable limit of detection, and reduced risk of analyte loss and contamination.

    This report is Section two of a series of reports on aeronautic instruments (Technical Report nos. 125 to 132, inclusive). This section discusses briefly barometric altitude determinations, and describes in detail the principal types of altimeters and barographs used in aeronautics during the recent war. This is followed by a discussion of performance requirements for such instruments and an account of the methods of testing developed by the Bureau of Standards. The report concludes with a brief account of the results of recent investigations. For accurate measurements of altitude, reference must also be made to thermometer readings of atmospheric temperature, since the altitude is not fixed by atmospheric pressure alone. This matter is discussed in connection with barometric altitude determination.

    2010-01-01

    This experimental study was conducted to examine the efficacy of repeated reading and wide reading practice interventions for high school students with severe reading disabilities. Effects on comprehension, fluency, and word reading were evaluated. Participants were 96 students with reading disabilities in grades 9–12. Students were paired within classes and pairs were randomly assigned to one of three groups: repeated reading (N = 33), wide reading (N = 34), or typical instruction (N = 29). Intervention was provided daily for approximately 15–20 minutes for 10 weeks. Results indicated no overall statistically significant differences for any condition, with effect sizes ranging from ?.31 to .27. Findings do not support either approach for severely impaired readers at the high school level. We hypothesize that these students require more intensive interventions that include direct and explicit instruction in word- and text-level skills as well as engaged reading practice with effective feedback.

    Context. Amongst the new techniques currently developed for high-resolution and high-dynamics imaging, the hypertelescope architecture is very promising for direct imaging of objects such as exoplanets. The performance of this instrument strongly depends on the co-phasing process accuracy. In a previous high-flux experimental study with an eight-telescope array, we successfully implemented a co-phasing system based on the joint use of a genetic algorithm and a sub-aperture piston phase diversity using the object itself as a source for metrology. Aims: To fit the astronomical context, we investigate the impact of photon noise on the co-phasing performance operating our laboratory prototype at low flux. This study provides experimental results on the sensitivity and the dynamics that could be reached for real astrophysical observations. Methods: Simulations were carried out to optimize the critical parameters to be applied in the co-phasing system running in the photon-counting regime. We used these parameters experimentally to acquire images with our temporal hypertelescope test bench for different photon flux levels. A data reduction method allows highly contrasted images to be extracted. Results: The optical path differences have been servo-controlled over one hour with an accuracy of 22.0 nm and 15.7 nm for 200 and 500 photons/frame, respectively. The data reduction greatly improves the signal-to-noise ratio and allows us to experimentally obtain highly contrasted images. The related normalized point spread function is characterized by a 1.1 × 10-4 and 5.4 × 10-5 intensity standard deviation over the dark field (for 15 000 snapshots with 200 and 500 photons/frame, respectively). Conclusions: This laboratory experiment demonstrates the potential of our hypertelescope concept, which could be directly transposed to a space-based telescope array. Assuming eight telescopes with a 30 cm diameter, the I-band limiting magnitude of the main star would be 7.3, allowing imaging of a companion with a 17.3 mag.

  12. Simulation visualization through dynamic instrumentation

    SciTech Connect

    Bisset, K.R.

    1998-09-01

    The goal of the instrument composition system is to allow a simulation user to dynamically create instruments as a simulation executes. Instruments can include graphical displays, data collectors, and debugging aides. Instruments are made up of small building blocks which can be easily combined into larger, more complex instruments. Through the sue of an Attribute Server (a distributed publication/subscription mechanism), the actors and instruments in a simulation can interact without direct knowledge of each other. Instead, each actor publishes the attributes which it has available. An instrument subscribes to the attributes in which it is interested, and is notified whenever the value of one of these attribute changes. An instrument can also publish attributes for use by other instruments. Since the Attribute Server is distributed, the publisher of an attribute need not execute on the same machine as the subscriber. This allows CPU intensive data visualization to execute on separate machines from the simulation, minimizing the impact on the simulation.

    Those Martian weather reports, received here daily from more than 200 million miles away, start right here at Viking l's meteorology instrument. Mounted atop the extended boom, the meteorology sensors face away from the spacecraft. They stand about four feet above the surface and measure atmospheric pressure, temperature, wind velocity and wind direction. The cable parallel to the boom is connected inside the spacecraft body with the electronics for operating the sensors, reading the data and preparing it for transmission to Earth. A second Mars weather station will begin operation next month when Viking 2 lands somewhere in the planet's northern latitude Viking 2 arrives at Mars and goes into orbit tomorrow (August 7).

  17. Early reading performance: a comparison of teacher-based and test-based assessments.

    PubMed

    Kenny, D T; Chekaluk, E

    1993-04-01

    An unresolved question in early screening is whether test-based or teacher-based assessments should form the basis of the classification of children at risk of educational failure. Available structured teacher rating scales are lacking in predictive validity, and teacher predictions of students likely to experience reading difficulties have yielded disappointing true positive rates, with teachers failing to identify the majority of severely disabled readers. For this study, three educational screening instruments were developed: (a) a single teacher rating, categorizing children into three levels of reading ability (advanced, average, poor); (b) a 15-item teacher questionnaire designed to measure students' cognitive and language ability, attentional and behavioral characteristics, and academic performance; and (c) a battery of language and reading tests that are predictive of, or correlate with, reading failure. The concurrent validity of each instrument was assessed in a sample of 312 Australian schoolchildren from kindergarten, Year 1, and Year 2. Students were assessed at the end of the 1989 school year after having completed 1, 2, or 3 years of schooling. The results suggest that the nature of the skills required for success in reading changes in the first 3 years of schooling. Both teachers and tests concur more closely as children progress through the elementary years and as the risk behavior (reading) becomes more accessible to direct measurement. Carefully focused teacher rating scales may be a cost-effective means of identifying children at risk of reading failure. Improved teacher rating scales should be developed and used to assist in the early screening process. PMID:8515187

  19. Reading Through Paint

    NASA Technical Reports Server (NTRS)

    2004-01-01

    Two-dimensional data matrix symbols, which contain encoded letters and numbers, are permanently etched on items for identification. They can store up to 100 times more information than traditional bar codes. While the symbols provide several advantages over bar codes, once they are covered by paint they can no longer be read by optical scanners. Since most products are painted eventually, this presents a problem for industries relying on the symbols for identification and tracking. In 1987, NASA s Marshall Space Flight Center began studying direct parts marking with matrix symbols in order to track millions of Space Shuttle parts. Advances in the technology proved that by incorporating magnetic properties into the paints, inks, and pastes used to apply the matrix symbols, the codes could be read by a magnetic scanner even after being covered with paint or other coatings. NASA received a patent for such a scanner in 1998, but the system it used for development was not portable and was too costly. A prototype was needed as a lead-in to a production model. In the summer of 2000, NASA began seeking companies to build a hand-held scanner that would detect the Read Through Paint data matrix identification marks containing magnetic materials through coatings.

    1991-06-01

    The feasibility of determining chlorinated, purgeable organic compounds (POCs) in aqueous samples by flame infrared-emission (FIRE) spectrometry was evaluated with a specially designed, multichannel, dispersive spectrometer having sufficient resolving power to prevent interference from large amounts of non-halogenated POCs that could also be present in the sample. The polychromator was based on a Czerny-Turner optical mounting with a 0.15-m focal length, a nominal focal ratio of f/3, and a reciprocal linear dispersion of 0.15 mum/mm in the first order. The HCl and CO(2) infrared emission bands (3.77 and 4.42 mum, respectively) were monitored in two analytical channels, while a third reference channel, used for background subtraction, monitored the H(2)O background emission at 2.8 mum. Instrumental performance was evaluated with dichloromethane, trichloromethane, trichloroethylene, 1,1,2,2-tetrachloroethane and monochlorobenzene as test compounds, and parameters such as the linear dynamic range, reproducibility, detection limit and signal-to-noise ratio, and extent of spectral crosstalk between channels were determined. The feasibility of performing a quantitative analysis of a two-component mixture of dichloromethane and trichloromethane at trace levels was demonstrated. PMID:18965190

    Despite significant changes in the treatment of common eye conditions like cataract and age-related macular degeneration, reading difficulty remains the most common complaint of patients referred for low vision services. Clinical reading tests have been widely used since Jaeger introduced his test types in 1854. A brief review of the major developments in clinical reading tests is provided, followed by a discussion of some of the main controversies in clinical reading assessment. Data for the Salisbury Eye Evaluation (SEE) study demonstrate that standardised clinical reading tests are highly predictive of reading performance under natural, real world conditions, and that discrepancies between self-reported reading ability and measured reading performance may be indicative of people who are at a pre-clinical stage of disability, but are at risk for progression to clinical disability. If measured reading performance is to continue to increase in importance as a clinical outcome measure, there must be agreement on what should be measured (e.g. speed or comprehension) and how it should be measured (e.g. reading silently or aloud). Perhaps most important, the methods for assessing reading performance and the algorithms for scoring reading tests need to be optimised so that the reliability and responsiveness of reading tests can be improved.

    We studied the cortical networks of Morse code reading with functional magnetic resonance imaging (fMRI). Four expert radio telegraphists performed two closely matched reading experiments, one in binaurally presented high speed Morse code and one in print. Performance was equal for both conditions. Reading single nouns in Morse code resulted in predominantly left-sided activation of the frontal and temporal perisylvian language areas, prefrontal cortex, and premotor cortex. In a within-subject comparison between reading Morse code and reading print, the activation pattern in the left temporoparietal association cortex was similar for both forms of reading, suggesting that reading Morse code shares part of its cortical networks with reading print.

    To become good readers, students need experience in reading for information. Science class is an ideal place for students to develop motivation and strategies for informational reading. Yet with the promotion of hands-on science, many teachers get the message that reading may be inappropriate in science. Nothing could be farther from the truth. According to Norris and Phillips (2003), science could not exist without a written language to record and disseminate ideas in ways that allow them to be tested, elaborated, and sometimes refuted. This article explores the integration of science and reading, and offers research-based methods to make the most of reading in science.

    Munster, J. B.

    2013-12-01

    The topsoil in the North Slope of Alaska contains millennia of labile carbon deposits. As the Arctic warms this labile carbon could be processed and released as CO2 and methane. As a remote area without infrastructure, a widespread carbon flux tower network to monitor the changing Arctic is not feasible. To address this, our collaborative team embarked on the summer 2013 Flux Observations of Carbon from an Airborne Laboratory (FOCAL) from Prudhoe Bay, AK, in August of 2013 to acquire flux measurements of CO2. Using Harvard's direct absorption CO2 cell to measure CO2 and isotopologue concentrations in conjunction with NOAA ATDD's Best Air Turbulence (BAT) probe, we measured local CO2 fluxes over a wide area of the north slope. These measurements were obtained from a low-flying aircraft (<10m) and cross-compared with tower measurements.

    Purpose: To evaluate discrepancies in Goldmann tonometer readings in eyes with varying degrees of corneal hydration and stromal amount. Methods. 6 Eye Bank eyes, donated by Florida Lion's Eye Bank, were evaluated. Each eye was affixed to a customized artificial orbit system with intraocular pressure (IOP) measured directly by a pressure transducer inserted into the vitreous and with a Goldmann tonometric readings. The eyes were dehydrated for 5-minute intervals in a 30% Dextran-BSS solution, with readings taken between each submersion. Once corneal thickness stabilized, a corneal trephination of 6mm was made. The corneal buttons were frozen and dehydrated by lyophilization and weighed. Results. Preliminary results show a possible overestimation in thicker corneas and an underestimation in thinner corneas, as previously published. Corresponding data on the weight of corneal material is provided. Further studies need to be conducted to determine statistical significance of the data. Conclusion. This study uses Eye Bank eyes with a protocol that produces results similar to previously published results. Further studies in correlating the amount of corneal stroma and discrepancies in Goldmann tonometer readings of intraocular pressure are important especially with the increasing acceptance of corneal refractive surgeries.

    Recent research has emphasized the poor finite-sample performance of the instrumental variables estimator when the instruments are weakly correlated with the regressors. The authors show how the canonical correlations between regressors and instruments can provide a measure of instrument relevance in the general multiple-instrument-multiple-regressor case. However, their simulation results indicate that any such relevance measure probably has little practical merit,

    The purpose of this narrative synthesis is to determine the reliability and validity of retell protocols for assessing reading comprehension of students in grades K–12. Fifty-four studies were systematically coded for data related to the administration protocol, scoring procedures, and technical adequacy of the retell component. Retell was moderately correlated with standardized measures of reading comprehension and, with older students, had a lower correlation with decoding and fluency. Literal information was retold more frequently than inferential, and students with learning disabilities or reading difficulties needed more supports to demonstrate adequate recall. Great variability was shown in the prompting procedures, but scoring methods were more consistent across studies. The influences of genre, background knowledge, and organizational features were often specific to particular content, texts, or students. Overall, retell has not yet demonstrated adequacy as a progress monitoring instrument. PMID:23125521

  20. GEO sounding using microwave instruments

    There are several microwave instruments in low Earth orbit (LEO) that are used for atmospheric temperature and humidity sounding by themselves and in conjunction with companion IR sounders. These instruments have achieved a certain degree of maturity and are undergoing a redesign to minimize their size, mass, and power requirements from the previous generation instruments. An example of these instruments is the AMSU-A series, now flying on POES and Aqua spacecraft, with the IR sounders HIRS3 and AIRS respectively. These older microwave instruments are going to be replaced by the ATMS instruments that will fly on NPP and NPOESS satellites with the CrIS IR sounder. A number of enabling technologies acquired from the ATMS instrument hardware design and data processing are directly applicable to performing similar microwave sounding on a geostationary platform. Because these technologies are already in place, they are readily available for the development of a geostationary orbit (GEO) microwave instrument, thereby avoiding costly technology development and minimizing the risk of not achieving the scientific requirements. In fact, the MMIC microwave components that were developed by ATMS for size and volume reduction are directly applicable to a GEO microwave sounder. The benefits of microwave sounders are well known. They penetrate non-precipitating cloud cover and allow for accurate soundings obtained with a collocated high spectral resolution IR sounder in up to 80% cloud cover. The key advantages of a microwave instrument in GEO will be its ability to provide high temporal resolution and uniform spatial resolution, and it will expand the utility of a collocated advanced IR sounder to cases in which partial cloud cover exists. A footprint in the order of 100 km by 100 km resolution with hemispherical coverage within one hour can be easily achieved for sounding channels in the 50 to 57 GHz range. A GEO microwave sounder will also allow mesoscale sampling of select regions.

    There are several microwave instruments in low Earth orbit (LEO) that are used for atmospheric temperature and humidity sounding in conjunction with companion IR sounders as well as by themselves. These instruments have achieved a certain degree of maturity and undergoing a redesign to minimize their size, mass, and power from the previous generation instruments. An example of these instruments is the AMSU-A series, now flying on POES and AQUA spacecraft with the IR sounders HIRS and AIRS. These older microwave instruments are going to be replaced by the ATMS instruments that will fly on NPP and NPOESS satellites with the CrIS sounder. A number of techniques learned from the ATMS project in instrument hardware design and data processing are directly applicable to a similar microwave sounder on a geosynchronous platform. These techniques can significantly simplify the design of a Geostationary orbit (GEO) microwave instrument, avoiding costly development and minimizing the risk of not being able to meet the scientific requirements. In fact, some of the 'enabling' technology, such as the use of MMIC microwave components (which is the basis for the ATMS' much reduced volume) can be directly applied to a GEO sounder. The benefits of microwave sounders are well known; for example, they penetrate non-precipitating cloud cover and allow for use of colocated IR observations in up to 80% cloud cover. The key advantages of a microwave instrument in GEO will be the ability to provide high temporal resolution as well as uniform spatial resolution and extend the utility of a colocated advanced IR sounder to cases in which partial cloud cover exists. A footprint of the order of 100 km by 100 km resolution with hemispherical coverage within one hour can be easily achieved for sounding channels in the 50 to 59 GHz range. A GEO microwave sounder will also allow mesoscale sampling of select regions.

    1974-01-01

    In order that the LST meet its scientific objectives and also be a National Astronomical Space Facility during the 1980's and 1990's, broad requirements have been levied by the scientific community. These scientific requirements can be directly translated into design requirements and specifications for the scientific instruments. The instrument ensemble design must be consistent with a 15-year operational lifetime. Downtime for major repair/refurbishment or instrument updating must be minimized. The overall efficiency and performance of the instruments should be maximized. Modularization of instruments and instrument subsystems, some degree of on-orbit servicing (both repair and replacement), on-axis location, minimizing the number of reflections within instruments, minimizing polarization effects, and simultaneous operation of the F/24 camera with other instruments, are just a few of the design guidelines and specifications which can and will be met in order that these broader scientific requirements be satisfied.-

    2006-01-01

    Synthetic LISA is a computer program for simulating the responses of the instrumentation of the NASA/ESA Laser Interferometer Space Antenna (LISA) mission, the purpose of which is to detect and study gravitational waves. Synthetic LISA generates synthetic time series of the LISA fundamental noises, as filtered through all the time-delay-interferometry (TDI) observables. (TDI is a method of canceling phase noise in temporally varying unequal-arm interferometers.) Synthetic LISA provides a streamlined module to compute the TDI responses to gravitational waves, according to a full model of TDI (including the motion of the LISA array and the temporal and directional dependence of the arm lengths). Synthetic LISA is written in the C++ programming language as a modular package that accommodates the addition of code for specific gravitational wave sources or for new noise models. In addition, time series for waves and noises can be easily loaded from disk storage or electronic memory. The package includes a Python-language interface for easy, interactive steering and scripting. Through Python, Synthetic LISA can read and write data files in Flexible Image Transport System (FITS), which is a commonly used astronomical data format.

    2007-04-01

    The Gravity Probe B (GP-B) experiment employs a unique state-of-the-art science instrument to measure the geodetic and frame-dragging precessions predicted by Einstein's theory of general relativity for gyroscopes orbiting a massive spinning body, in this case the Earth. The GP-B instrument comprises four electrostatically suspended gyroscopes, each of which is independently subject to both the geodetic and frame-dragging precessions, and a telescope that tracks the guide star, IM Pegasi. Each gyroscope is read out with a dc SQUID system utilizing the London magnetic moment of the spinning gyroscope. The two axes of the telescope are read out with an image divider assembly, solid-state photo detectors and JFET preamplifiers. The telescope and gyroscopes are mechanically and thermally linked by a fused quartz block, which forms the metrology bench for the experiment. The instrument is located in a probe/helium dewar system, which provides a low-temperature environment of about 2.7 K for the instrument, as well as the ultra-low magnetic field, the ultrahigh magnetic shielding of the on-orbit ambient magnetic field, and the ultrahigh vacuum environments. The instrument was designed to allow a measurement of the geodetic and frame-dragging precessions to an accuracy of better than 0.5 mill-arc second/year for one year of science data collection. The instrument also provides the signals needed for drag-free and attitude control of the space vehicle. This presentation will include a description of the instrument and its principal on-orbit performance characteristics. Many persons at various institutions contributed to the development of the instrument. Numerous contributed presentations in a poster session will provide more detail.

  14. Can India's ``literate'' read?

    NASA Astrophysics Data System (ADS)

    Kothari, Brij; Bandyopadhyay, Tathagata

    2010-12-01

    This paper takes a close look at India's literacy rate by exploring whether the officially "literate" can read and at what level. In a large sample, aged 7+, drawn from four Hindi-speaking states, two methods were used to measure literacy. One was the standard Census Method (CM) which relies on self-reporting and the other was a Reading Method (RM) which required the same individuals to actually read a simple text at grade 2 level. The findings revealed a substantial difference between the reading literacy rates obtained by CM and RM. CM over-reported RM by 16%. The overestimation was higher for males. Decoding skills were found to erode in most cases after completion of primary schooling, assuming no further education. A minimum grade 8-9 education was required for decoding skills to not deteriorate after schooling.

  16. Binocular advantages in reading.

    PubMed

    Jainta, Stephanie; Blythe, Hazel I; Liversedge, Simon P

    2014-03-01

    Reading, an essential skill for successful function in today's society, is a complex psychological process involving vision, memory, and language comprehension. Variability in fixation durations during reading reflects the ease of text comprehension, and increased word frequency results in reduced fixation times. Critically, readers not only process the fixated foveal word but also preprocess the parafoveal word to its right, thereby facilitating subsequent foveal processing. Typically, text is presented binocularly, and the oculomotor control system precisely coordinates the two frontally positioned eyes online. Binocular, compared to monocular, visual processing typically leads to superior performance, termed the "binocular advantage"; few studies have investigated the binocular advantage in reading. We used saccade-contingent display change methodology to demonstrate the benefit of binocular relative to monocular text presentation for both parafoveal and foveal lexical processing during reading. Our results demonstrate that denial of a unified visual signal derived from binocular inputs provides a cost to the efficiency of reading, particularly in relation to high-frequency words. Our findings fit neatly with current computational models of eye movement control during reading, wherein successful word identification is a primary determinant of saccade initiation. PMID:24530062

    NASA Astrophysics Data System (ADS)

    Sarma, Sreeramula Rajeswara

    The earliest astronomical instruments used in India were the gnomon and the water clock. In the early seventh century, Brahmagupta described ten types of instruments, which were adopted by all subsequent writers with minor modifications. Contact with Islamic astronomy in the second millennium AD led to a radical change. Sanskrit texts began to lay emphasis on the importance of observational instruments. Exclusive texts on instruments were composed. Islamic instruments like the astrolabe were adopted and some new types of instruments were developed. Production and use of these traditional instruments continued, along with the cultivation of traditional astronomy, up to the end of the nineteenth century.

    TRU VU was developed in response to the growing need for real time rig instrumentation that interface various rig systems into a common database. TRU VU is a WITS compatible (Wellsite Information Transfer Standard) system that logs drilling data and MWD data into a common database. Real time data as well as historical data can be viewed from up to eight locations on the rig or from numerous locations in communication with the rig. The TRU VU well monitoring package can be configured to operate manned or unmanned depending on the specific requirements of the operator or drilling contractor. TRU VU does not require a drilling recorder and is totally independent of all rig systems. For example, depth is monitored directly from the draw works and can monitor pipe movement while drilling or tripping. Weight on bit is zeroed automatically on each connection and does not require manual input.

  8. Mars Miniature Science Instruments

    NASA Technical Reports Server (NTRS)

    2006-01-01

    For robotic Mars missions, all the science information is gathered through on-board miniature instruments that have been developed through many years of R&D. Compared to laboratory counterparts, the rover instruments require miniaturization, such as low mass (1-2 kg), low power (> 10 W) and compact (1-2 liter), yet with comparable sensitivity. Since early 1990's, NASA recognized the need for the miniature instruments and launched several instrument R&D programs, e.g., PIDDP (Planetary Instrument Definition and Development). However, until 1998, most of the instrument R&D programs supported only up to a breadboard level (TRL 3, 4) and there is a need to carry such instruments to flight qualifiable status (TU 5, 6) to respond to flight AOs (Announcement of Opportunity). Most of flight AOs have only limited time and financial resources, and can not afford such instrument development processes. To bridge the gap between instrument R&D programs and the flight instrument needs, NASA's Mars Technology Program (MTP) created advanced instrumentation program, Mars Instrument Development Project (MIDP). MIDP candidate instruments are selected through NASA Research Announcement (NRA) process [l]. For example, MIDP 161998-2000) selected and developed 10 instruments, MIDP II (2003-2005) 16 instruments, and MIDP III (2004-2006) II instruments.Working with PIs, JPL has been managing the MIDP tasks since September 1998. All the instruments being developed under MIDP have been selected through a highly competitive NRA process, and employ state-of-the-art technology. So far, four MIDP funded instruments have been selected by two Mars missions (these instruments have further been discussed in this paper).

  9. Assessing Comprehension During Reading with the Reading Strategy Assessment Tool (RSAT)

    PubMed Central

    Magliano, Joseph P.; Millis, Keith K.; Levinstein, Irwin

    2011-01-01

    Comprehension emerges as the results of inference and strategic processes that support the construction of a coherent mental model for a text. However, the vast majority of comprehension skills tests adopt a format that does not afford an assessment of these processes as they operate during reading. This study assessed the viability of the Reading Strategy Assessment Tool (RSAT), which is an automated computer-based reading assessment designed to measure readers’ comprehension and spontaneous use of reading strategies while reading texts. In the tool, readers comprehend passages one sentence at a time, and are asked either an indirect (“What are your thoughts regarding your understanding of the sentence in the context of the passage?”) or direct (e.g., why X?) question after reading each pre-selected target sentence. The answers to the indirect questions are analyzed on the extent that they contain words associated with comprehension processes. The answers to direct questions are coded for the number of content words in common with an ideal answer, which is intended to be an assessment of emerging comprehension. In the study, the RSAT approach was shown to predict measures of comprehension comparable to standardized tests. The RSAT variables were also shown to correlate with human ratings. The results of this study constitute a “proof of concept” and demonstrate that it is possible to develop a comprehension skills assessment tool that assesses both comprehension and comprehension strategies.

    1992-10-01

    The accelerator instrumentation played a vital role in commissioning the ALS injector accelerator. It helped us to see whether electron dynamics agreed with our theoretical predictions and important beam parameters met the design specifications. It helped us to see where beam losses occurred and why. In this paper we will start with a brief description of the ALS accelerator complex and the expected performance of it. Then we will describe each diagnostics instrument by its construction, operational principle, requirements, and our experiences with it. We will describe the wall current monitor, the scintillator, the Faraday cup, the beam collimator, the beam position monitor, the direct-current current transformer (DCCT), the traveling wave electrodes the Sabersky finger, and other special instruments. Finally, we will go into some detail on how we measured the beam emittances, the closed orbit, and the betatron tunes.

    2014-11-01

    Early identification of dyslexia would be fundamental to prevent the negative consequences of delayed treatment in the social, psychological and occupational domains. Movement-related potentials of dyslexic children are characterized by inadequate ability to program movements and reduced capacity to evaluate their performance and to correct their errors. Reading-related potentials recorded during different reading conditions elicit a series of positive and negative components with specific functional meaning and with a characteristic spatial-temporal pattern. These reading-related potentials, when analyzed with sLORETA, show significantly different patterns of activation when comparing self-paced reading aloud to passive viewing of single letters. Comparison of fMRI and sLORETA during both tasks showed that the cortical region with the widest inter-modality similarities is the middle-superior temporal lobe during self-paced reading aloud. Neuropsychological studies have shown the existence of clinical subtypes of dyslexia; these studies have been confirmed by the results of ICA applied to the EEG. Dyslexia can be defined as a disorder of programming and integrating ideokinetic elements, associated with a deficiency in the fast processing and integration of sensory information, with reduced efficiency of error systems analysis. Each of these phenomena occurs at different levels of the central nervous system and at different times. PMID:25193560

  5. What and where in mirror reading.

    PubMed

    Ilg, Rüdiger; Dauner, Ruth; Wohlschläger, Afra Maria; Liebau, Yasmin; Zihl, Josef; Mühlau, Mark

    2010-09-01

    In a combined voxel-based morphometry and functional magnetic resonance imaging study on the practice of mirror reading, we recently found a shift of activation from right superior parietal to right dorsal occipital cortex and a corresponding increase of gray matter. We interpreted this shift of activation and the corresponding structural changes as a shift from effortful visuospatial transformation to a more direct processing of mirrored words (Ilg et al., 2008). To test this hypothesis, we now analyzed brain activation patterns associated with different aspects of mirror reading. Activation at the dorsal occipital cortex and bilateral parietal cortex (dorsal visual stream) was related to inverse text processing, whereas activation of areas at the inferior and ventral occipitotemporal cortex (ventral visual stream) was associated with decoding of mirrored words. This indicates that the dichotomy of content-related ("what") and process-related ("where") higher visual functions also applies to mirror reading. PMID:20345597

    2012-04-13

    The ability to recognize strings of letters as words, also known as orthographic processing, is a key component of reading. The ability to develop this skill has commonly been attributed to prior acquisition of a spoken language, but Grainger et al. argue that linguistic ability may instead be related to simple object recognition. To test this, Grainger and colleagues studied orthographic processing in a group of captive but freely ranging baboons, who learned to read and distinguish real English words from non-words with remarkable accuracy. These results suggest that a basic ability to recognize words does not require complex linguistic understanding.

  10. XS: a FASTQ read simulator

    PubMed Central

    2014-01-01

    Background The emerging next-generation sequencing (NGS) is bringing, besides the natural huge amounts of data, an avalanche of new specialized tools (for analysis, compression, alignment, among others) and large public and private network infrastructures. Therefore, a direct necessity of specific simulation tools for testing and benchmarking is rising, such as a flexible and portable FASTQ read simulator, without the need of a reference sequence, yet correctly prepared for producing approximately the same characteristics as real data. Findings We present XS, a skilled FASTQ read simulation tool, flexible, portable (does not need a reference sequence) and tunable in terms of sequence complexity. It has several running modes, depending on the time and memory available, and is aimed at testing computing infrastructures, namely cloud computing of large-scale projects, and testing FASTQ compression algorithms. Moreover, XS offers the possibility of simulating the three main FASTQ components individually (headers, DNA sequences and quality-scores). Conclusions XS provides an efficient and convenient method for fast simulation of FASTQ files, such as those from Ion Torrent (currently uncovered by other simulators), Roche-454, Illumina and ABI-SOLiD sequencing machines. This tool is publicly available at http://bioinformatics.ua.pt/software/xs/. PMID:24433564

    Schotter, Elizabeth R; Angele, Bernhard; Rayner, Keith

    2012-01-01

    The present review summarizes research investigating how words are identified parafoveally (and foveally) in reading. Parafoveal and foveal processing are compared when no other concurrent task is required (e.g., in single-word recognition tasks) and when both are required simultaneously (e.g., during reading). We first review methodologies used to study parafoveal processing (e.g., corpus analyses and experimental manipulations, including gaze-contingent display change experiments such as the boundary, moving window, moving mask, and fast priming paradigms). We then turn to a discussion of the levels of representation at which words are processed (e.g., orthographic, phonological, morphological, lexical, syntactic, and semantic). Next, we review relevant research regarding parafoveal processing, summarizing the extent to which words are processed at each of those levels of representation. We then review some of the most controversial aspects of parafoveal processing, as they relate to reading: (1) word skipping, (2) parafoveal-on-foveal effects, and (3) n + 1 and n + 2 preview benefit effects. Finally, we summarize two of the most advanced models of eye movements during reading and how they address foveal and parafoveal processing. PMID:22042596

    PubMed

    Horowitz-Kraus, Tzipi; Cicchino, Nicole; Amiel, Merav; Holland, Scott K; Breznitz, Zvia

    2014-10-01

    A reading acceleration program known to improve reading fluency in Hebrew-speaking adults was tested for its effect on children. Eighty-nine Hebrew- and English-speaking children with reading difficulties were divided into a waiting list group and two training groups (Hebrew and English) and underwent 4 weeks of reading acceleration training. Results of pre- and post-testing of reading abilities point to a significant main effect of the test, demonstrating improvements in silent contextual reading speed, reading comprehension, and speed of processing in both Hebrew and English training groups as compared to their performance before the intervention. This study indicates that the Reading Acceleration Program might be an effective program for improving reading abilities in children, independent of language. PMID:24919641

  2. The use and calibration of read-out streaks to increase the dynamic range of the Swift Ultraviolet/Optical Telescope

    NASA Astrophysics Data System (ADS)

    Page, M. J.; Kuin, N. P. M.; Breeveld, A. A.; Hancock, B.; Holland, S. T.; Marshall, F. E.; Oates, S.; Roming, P. W. A.; Siegel, M. H.; Smith, P. J.; Carter, M.; De Pasquale, M.; Symeonidis, M.; Yershov, V.; Beardmore, A. P.

    The dynamic range of photon counting micro-channel-plate (MCP) intensified charged-coupled device (CCD) instruments such as the Swift Ultraviolet/Optical Telescope (UVOT) and the XMM-Newton Optical Monitor (XMM-OM) is limited at the bright end by coincidence loss, the superposition of multiple photons in the individual frames recorded by the CCD. Photons which arrive during the brief period in which the image frame is transferred for read out of the CCD are displaced in the transfer direction in the recorded images. For sufficiently bright sources, these displaced counts form read-out streaks. Using UVOT observations of Tycho-2 stars, we investigate the use of these read-out streaks to obtain photometry for sources which are too bright (and hence have too much coincidence loss) for normal aperture photometry to be reliable. For read-out-streak photometry, the bright-source limiting factor is coincidence loss within the MCPs rather than the CCD. We find that photometric measurements can be obtained for stars up to 2.4 mag brighter than the usual full-frame coincidence-loss limit by using the read-out streaks. The resulting bright-limit Vega magnitudes in the UVOT passbands are UVW2 = 8.80, UVM2 = 8.27, UVW1 = 8.86, u = 9.76, b = 10.53, v = 9.31 and White = 11.71; these limits are independent of the windowing mode of the camera. We find that a photometric precision of 0.1 mag can be achieved through read-out streak measurements. A suitable method for the measurement of read-out streaks is described and all necessary calibration factors are given.

  17. Paraprofessional Reading Tutors: Assessment of the Edmark Reading Program and Flexible Teaching1

    PubMed Central

    Andersen, Barbara L.; Licht, Barbara G.; Ullmann, Rina K.; Buck, Sylvia T.; Redd, William H.

    2009-01-01

    The purpose of the study was to assess the effectiveness of two strategies for using undergraduate paraprofessionals as tutors for first-grade children with reading difficulties. The two groups of undergraduates taught first graders the same 150 words, and both reinforced (socially and materially) correct performances. However, one group employed a programmed method of word presentation (i.e., the Edmark Reading Program), while the other group of tutors was allowed flexibility in the pacing and methods for presenting words. The performance of each reading group was compared to that of a control group who engaged in educational activities not directly related to reading. Thirty-six poor readers were randomly assigned to one of the three groups. Subjects were tutored after school by university undergraduates for an average of twenty-three 40-minute sessions. Children in both reading groups showed significantly more improvement than controls on an oral reading posttest of the 150 criterion words. Treatment effects did not emerge on a test composed mainly of noncriterion words. PMID:19668353

  18. The relationship between knowing a word and reading it aloud in children's word reading development.

    PubMed

    Nation, Kate; Cocksey, Joanne

    2009-07-01

    This experiment examined the item-level relationship between 7-year-olds' ability to read words aloud and their knowledge of the same words in the oral domain. Two types of knowledge were contrasted: familiarity with the phonological form of the word (lexical phonology), measured by auditory lexical decision, and semantic knowledge, measured by a definitions task. Overall, there was a robust relationship between word knowledge and reading aloud success. The association was stronger when words contained irregular spelling-sound correspondences. There was no evidence that a deeper or more semantic knowledge of words was more closely related to reading aloud success beyond the association between reading success and familiarity with the phonological form of the same words. This finding is not compatible with models that see semantics as contributing directly to the reading aloud process, at least during the relatively early stages of reading development. More critical was whether or not a word was considered a lexical item, as indexed by auditory lexical decision performance. PMID:19410262

  3. Mobile Instruments Measure Atmospheric Pollutants

    NASA Technical Reports Server (NTRS)

    2009-01-01

    As a part of NASA's active research of the Earth s atmosphere, which has included missions such as the Atmospheric Laboratory of Applications and Science (ATLAS, launched in 1992) and the Total Ozone Mapping Spectrometer (TOMS, launched on the Earth Probe satellite in 1996), the Agency also performs ground-based air pollution research. The ability to measure trace amounts of airborne pollutants precisely and quickly is important for determining natural patterns and human effects on global warming and air pollution, but until recent advances in field-grade spectroscopic instrumentation, this rapid, accurate data collection was limited and extremely difficult. In order to understand causes of climate change and airborne pollution, NASA has supported the development of compact, low power, rapid response instruments operating in the mid-infrared "molecular fingerprint" portion of the electromagnetic spectrum. These instruments, which measure atmospheric trace gases and airborne particles, can be deployed in mobile laboratories - customized ground vehicles, typically - to map distributions of pollutants in real time. The instruments must be rugged enough to operate rapidly and accurately, despite frequent jostling that can misalign, damage, or disconnect sensitive components. By measuring quickly while moving through an environment, a mobile laboratory can correlate data and geographic points, revealing patterns in the environment s pollutants. Rapid pollutant measurements also enable direct determination of pollutant sources and sinks (mechanisms that remove greenhouse gases and pollutants), providing information critical to understanding and managing atmospheric greenhouse gas and air pollutant concentrations.

The Argus II retinal prosthesis system was recently awarded CE approval for commercial use in Europe. While retinal prosthesis users have achieved remarkable visual improvement to the point of reading letters and short sentences, the reading process is still fairly cumbersome. This study investigates the possibility of using an epiretinal prosthesis to stimulate visual braille as a sensory substitution for reading written letters and words. The Argus II retinal prosthesis system, used in this study, includes a 10?×?6 electrode array implanted epiretinally, a tiny video camera mounted on a pair of glasses, and a wearable computer that processes the video and determines the stimulation current of each electrode in real time. In the braille reading system, individual letters are created by a subset of dots from a 3 by 2 array of six dots. For the visual braille experiment, a grid of six electrodes was chosen out of the 10?×?6 Argus II array. Groups of these electrodes were then directly stimulated (bypassing the camera) to create visual percepts of individual braille letters. Experiments were performed in a single subject. Single letters were stimulated in an alternative forced choice (AFC) paradigm, and short 2–4-letter words were stimulated (one letter at a time) in an open-choice reading paradigm. The subject correctly identified 89% of single letters, 80% of 2-letter, 60% of 3-letter, and 70% of 4-letter words. This work suggests that text can successfully be stimulated and read as visual braille in retinal prosthesis patients. PMID:23189036

    2014-01-01

    Through a four month Clinical Process Improvement Leadership Program, professionals at North Shore Medical Center in Massachusetts developed a process improvement to gain efficiency in communicating urgently requested x-ray results, or "wet reads." The initial steps included summoning a diverse team, mapping the process in detail, and clearly defining the problem. Once the problem was defined, the team brainstormed potential solutions and constructed a priority/pay-off matrix. By using the Plan Do Study Act (PDSA) system, a repeating cycle of activity that tests the new experimental work flow by tracking, adjusting, tweaking, and tracking again, efforts were built upon until the goal was met.The average wet read turnaround time went from 44 minutes to 15 minutes, a reduction of 66%.

    The Great White Whale truly comes alive in this creative and thoughtful website created by artist Angela Cockayne and writer Philip Hoare. While collaborating in Spring 2011 for Peninsula Arts at Plymouth University to curate the ââ?¬Ĺ?Dominionââ?¬Âť whale symposium and exhibition, they came to believe that there was something more to their ââ?¬Ĺ?Moby Dickââ?¬Âť obsession. Thus, in September 2012, they launched an online version of Herman Melville's classic work featuring all 135 chapters read on audio by a mixture of "the celebrated and the unknown" for free download to the public. The project is chronicled via a podcast on the main site, Facebook, SoundCloud, and iTunes. Chapters to watch for include readings by Neil Tennant, Nigel Williams, and noted actress Tilda Swinton.

  8. Electronic Thermometer Readings

    NASA Technical Reports Server (NTRS)

    2001-01-01

    NASA Stennis' adaptive predictive algorithm for electronic thermometers uses sample readings during the initial rise in temperature and applies an algorithm that accurately and rapidly predicts the steady state temperature. The final steady state temperature of an object can be calculated based on the second-order logarithm of the temperature signals acquired by the sensor and predetermined variables from the sensor characteristics. These variables are calculated during tests of the sensor. Once the variables are determined, relatively little data acquisition and data processing time by the algorithm is required to provide a near-accurate approximation of the final temperature. This reduces the delay in the steady state response time of a temperature sensor. This advanced algorithm can be implemented in existing software or hardware with an erasable programmable read-only memory (EPROM). The capability for easy integration eliminates the expense of developing a whole new system that offers the benefits provided by NASA Stennis' technology.

    1997-01-01

    Abstract The Read Codes are a hierarchically-arranged controlled clinical vocabulary introduced in the early 1980s and now consisting of three maintained versions of differing complexity. The code sets are dynamic, and are updated quarterly in response to requests from users including clinicians in both primary and secondary care, software suppliers, and advice from a network of specialist healthcare professionals. The codes' continual evolution of content, both across and within versions, highlights tensions between different users and uses of coded clinical data. Internal processes, external interactions and new structural features implemented by the NHS Centre for Coding and Classification (NHSCCC) for user interactive maintenance of the Read Codes are described, and over 2000 items of user feedback episodes received over a 15-month period are analysed.

  10. Reading Text While Driving

    2015-01-01

    Objective In this study, we investigated how drivers adapt secondary-task initiation and time-sharing behavior when faced with fluctuating driving demands. Background Reading text while driving is particularly detrimental; however, in real-world driving, drivers actively decide when to perform the task. Method In a test track experiment, participants were free to decide when to read messages while driving along a straight road consisting of an area with increased driving demands (demand zone) followed by an area with low demands. A message was made available shortly before the vehicle entered the demand zone. We manipulated the type of driving demands (baseline, narrow lane, pace clock, combined), message format (no message, paragraph, parsed), and the distance from the demand zone when the message was available (near, far). Results In all conditions, drivers started reading messages (drivers’ first glance to the display) before entering or before leaving the demand zone but tended to wait longer when faced with increased driving demands. While reading messages, drivers looked more or less off road, depending on types of driving demands. Conclusions For task initiation, drivers avoid transitions from low to high demands; however, they are not discouraged when driving demands are already elevated. Drivers adjust time-sharing behavior according to driving demands while performing secondary tasks. Nonetheless, such adjustment may be less effective when total demands are high. Application This study helps us to understand a driver’s role as an active controller in the context of distracted driving and provides insights for developing distraction interventions.

  13. Optical distance measuring instrument

    NASA Technical Reports Server (NTRS)

    Abshire, J. B. (inventor)

    1986-01-01

    An optical instrument, such as a stability monitor or a target range finder, uses an unstabilized laser to project a composite optical signal of coherent light having two naturally occurring longitudinal mode components. A beamsplitter divides the signal into a reference beam which is directed toward one photodetector and a transmitted beam which illuminates and is reflected from a distant target onto a second photodetector optically isolated from the first photodetector. Both photodetectors are operated on the square law principle to provide electrical signals modulated at a frequency equal to the separation between the frequencies of the two longitudinal mode components of the optical signal projected by the laser. Slight movement of the target may be detected and measured by electrically monitoring the phase difference between the two signals provided by the photodetectors and the range of the target measured with the aid of a microprocessor by changing the separation between the longitudinal modes by shifting the length of the resonator cavity in an iterative series of increments.

  14. Load sensing surgical instruments.

    2009-12-01

    Force and pressure sensing technology applied to smart surgical instruments as well as implants allow to give a direct feedback of loads to the surgeon lead to better reliability and success of surgical operations. A common technology used for sensors is low-cost piezoresistive thick-film technology. However, the standard thick-film firing conditions degrade the properties of medical alloys. In order to avoid this problem, the solution is to decrease the firing temperature of thick films. This work presents the development and characterisation of low-firing thick-film systems (dielectrics, resistors and conductors), formulated to achieve chemical and thermal expansion compatibility with an austenitic stainless steel medical alloy. Adherence tests and results on electrical properties of these systems: resistance, temperature coefficient of resistance (TCR) are presented. It was found that the main issue in these systems lies in mastering the materials interactions during firing, especially at the silver-based resistor terminations. The interaction of silver, resistor and dielectric tends to give rise to highly resistive zones at the terminations, affecting reliability. This can be circumvented by post-firing the resistor terminations at a moderate temperature. PMID:18679770

  15. Detectors for Tomorrow's Instruments

    2009-01-01

    Cryogenically cooled superconducting detectors have become essential tools for a wide range of measurement applications, ranging from quantum limited heterodyne detection in the millimeter range to direct searches for dark matter with superconducting phonon detectors operating at 20 mK. Superconducting detectors have several fundamental and practical advantages which have resulted in their rapid adoption by experimenters. Their excellent performance arises in part from reductions in noise resulting from their low operating temperatures, but unique superconducting properties provide a wide range of mechanisms for detection. For example, the steep dependence of resistance with temperature on the superconductor/normal transition provides a sensitive thermometer for calorimetric and bolometric applications. Parametric changes in the properties of superconducting resonators provides a mechanism for high sensitivity detection of submillimeter photons. From a practical point of view, the use of superconducting detectors has grown rapidly because many of these devices couple well to SQUID amplifiers, which are easily integrated with the detectors. These SQUID-based amplifiers and multiplexers have matured with the detectors; they are convenient to use, and have excellent noise performance. The first generation of fully integrated large scale superconducting detection systems are now being deployed. I will discuss the prospects for a new generation of instruments designed to take full advantage of the revolution in detector technology.

    The goals of micro-arcsecond space mission rely on the limiting performance associated to the selected instrumental configuration and observing conditions. In particular, variation of the instrumental response over the field, with wavelength and in time, are potentially critical. We discuss the impact on the data quality and how the science data can be used to trace directly and in real time the astrometric instrument response of Gaia. This is one of the driver philosophies behind the Astrometric Instrument Model (AIM) concept. We show results from the test campaigns carried on throughout the 2013.

    The Visible Integral-Field Replicable Unit Spectrograph (VIRUS) instrument will be installed at the Hobby-Eberly Telescope† in the near future. The instrument will be housed in two enclosures that are mounted adjacent to the telescope, via the VIRUS Support Structure (VSS). We have designed the enclosures to support and protect the instrument, to enable servicing of the instrument, and to cool the instrument appropriately while not adversely affecting the dome environment. The system uses simple HVAC air handling techniques in conjunction with thermoelectric and standard glycol heat exchangers to provide efficient heat removal. The enclosures also provide power and data transfer to and from each VIRUS unit, liquid nitrogen cooling to the detectors, and environmental monitoring of the instrument and dome environments. In this paper, we describe the design and fabrication of the VIRUS enclosures and their subsystems.

    The ALADDIN project aims at detecting warm dust populations around nearby main sequence stars. In order to achieve the significantly improved sensitivity with respect to existing instruments, the architecture of the system is focused and optimised for the mission: ALADDIN implements the nulling interferometry technique at the focal plane of a 2-telescope interferometer mounted on a rotating structural beam. Concerning the beam combining nulling instrument, the ALADDIN design is inherited from a Definition Study of the VLTI/GENIE instrument. In this paper, we demonstrate how the ALADDIN instrument preliminary definition can be made simpler and more representative of a space instrument than GENIE thanks to both the outstanding atmospheric properties of Dome C and the dedicated architecture of the system. Finally, we discuss the compatibility of the instrument with the Antarctic environment and constraints, and underline the experimental and industrial know-how learnt from the MAII and PERSEE nulling breadboards in which our Team is also involved.

    An overview of the current status of the Thirty Meter Telescope (TMT) instrumentation program is presented. Conceptual designs for the three first light instruments (IRIS, WFOS and IRMS) are in progress, as well as feasibility studies of MIRES. Considerable effort is underway to understand the end-to-end performance of the complete telescopeadaptive optics-instrument system under realistic conditions on Mauna Kea. Highly efficient operation is being designed into the TMT system, based on a detailed investigation of the observation workflow to ensure very fast target acquisition and set up of all subsystems. Future TMT instruments will almost certainly involve contributions from institutions in many different locations in North America and partner nations. Coordinating and optimizing the design and construction of the instruments to ensure delivery of the best possible scientific capabilities is an interesting challenge. TMT welcomes involvement from all interested instrument teams.

    It is pointed out that no instrument is sensitive to only one oceanographic variable; rather, each responds to a combination of atmospheric and oceanic phenomena. This complicates data interpretation and usually requires that a number of observations, each sensitive to somewhat different phenomena, be combined to provide unambiguous information. The distinction between active and passive instruments is described. A block diagram illustrating the steps necessary to convert data from satellite instruments into oceanographic information is included, as is a diagram illustrating the operation of a radio-frequency radiometer. Attention is also given to the satellites that carry the various oceanographic instruments.

    Westinghouse Hanford Company Project W-211 is responsible for providing the system capabilities to remove radioactive waste from ten double-shell tanks used to store radioactive wastes on the Hanford Site in Richland, Washington. The project is also responsible for measuring tank waste slurry properties prior to injection into pipeline systems, including the Replacement of Cross-Site Transfer System. This report summarizes studies of the appropriateness of the instrumentation specified for use in Project W-211. The instruments were evaluated in a test loop with simulated slurries that covered the range of properties specified in the functional design criteria. The results of the study indicate that the compact nature of the baseline Project W-211 loop does not result in reduced instrumental accuracy resulting from poor flow profile development. Of the baseline instrumentation, the Micromotion densimeter, the Moore Industries thermocouple, the Fischer and Porter magnetic flow meter, and the Red Valve Pressure transducer meet the desired instrumental accuracy. An alternate magnetic flow meter (Yokagawa) gave nearly identical results as the baseline fischer and Porter. The Micromotion flow meter did not meet the desired instrument accuracy but could potentially be calibrated so that it would meet the criteria. The Nametre on-line viscometer did not meet the desired instrumental accuracy and is not recommended as a quantitative instrument although it does provide qualitative information. The recommended minimum set of instrumentation necessary to ensure the slurry meets the Project W-058 acceptance criteria is the Micromotion mass flow meter and delta pressure cells.

    Rosete-Aguilar, Martha; Rayces, Juan L

    2002-11-01

    The eye can rotate to accommodate the angular position of an object and the distance of the object from it. The rotation of the eye inside its socket to align its visual axis in the direction of an off-axis image may introduce full or partial vignetting when one is looking through a visual instrument with a real exit pupil. We analyze the effects of vignetting owing to rotation of the eye in visual instruments with real exit pupils. PMID:12412650

    Purpose: To investigate parameters related to fluency, reading comprehension and phonological processing (operational and short-term memory) and identify potential correlation between the variables in Dyslexia and in the absence of reading difficulties. Method: One hundred and fifteen students from the third to eighth grade of elementary school were grouped into a Control Group (CG) and Group with Dyslexia (GDys). Reading of words, pseudowords and text (decoding); listening and reading comprehension; phonological short-term and working memory (repetition of pseudowords and Digit Span) were evaluated. Results: The comparison of the groups showed significant differences in decoding, phonological short-term memory (repetition of pseudowords) and answers to text-connecting questions (TC) on reading comprehension, with the worst performances identified for GDys. In this group there were negative correlations between pseudowords repetition and TC answers and total score, both on listening comprehension. No correlations were found between operational and short-term memory (Digit Span) and parameters of fluency and reading comprehension in dyslexia. For the sample without complaint, there were positive correlations between some parameters of reading fluency and repetition of pseudowords and also between answering literal questions in listening comprehension and repetition of digits on the direct and reverse order. There was no correlation with the parameters of reading comprehension. Conclusion: GDys and CG showed similar performance in listening comprehension and in understanding of explicit information and gap-filling inference on reading comprehension. Students of GDys showed worst performance in reading decoding, phonological short-term memory (pseudowords) and on inferences that depends on textual cohesion understanding in reading. There were negative correlations between pseudowords repetition and TC answers and total score, both in listening comprehension. PMID:25101021

    The SOAR Telescope, near completion on Cerro Pachon - Chile, will carry Instrument Support Modules (ISMs) mounted at the two Nasmyth foci. Each ISM has three focal stations and is capable of making rapid instrument changes between them. Both ISMs also carry a Comparison Lamp System (CLS), guider and an acquisition camera, which are shared between the three instruments. One ISM supports IR instruments. The other is used for "Optical" instruments operating at wavelengths below 900nm. Beam steering mechanisms direct light from the SOAR science field or the CLS to the instrument in use. In the IR-ISM, light is sent to the lateral ports by dichroic mirrors which reflect IR and transmit wavelengths from 400-900nm to the guider. In the Optical-ISM, light is directed to the lateral ports by the use of first surface pick-off mirrors. Guiding is done off-axis. During operation, both ISMs can be rotated by 360° and must carefully control differential flexure between the guider and focal planes. A method of accurate relative flexure measurement has been developed where the ISM is rotated on its handling cart while carrying instrument mass simulators which reproduce its nominal payloads. In this paper, the ISM and its support sub-modules are described. Results of flexure measurements and tests of the CLS are provided.
