    One of the most critical and effective parameters in increasing areal density is the flying height or spacing between the read-write head and the recording disk medium. As the flying height reduces to near contact, the head flies around 5 nm about the disk surface. To date, optical interferometry has been the major means for the characterization of this parameter. However, it is difficult to use it directly to measure the flying height on a sealed drive. To circumvent this limitation, a system based upon CD-ROM optics has been designed. The results from the system are correlated to measurements of suspension arm movement and disk flutter using poly-vinylidine-flouride (PVdF) strain sensors. A CD-ROM drive utilizes a laser with photodiodes to read data from the disk. The photo detector output responds linearly to changes in the lens-disk separation. In our system two CD-ROM heads are located within a rig that allows independent positioning in all three planes. The optics are configured to reflect off of a typical hard disk drive disk and the slider. To validate its performance a thin (110 micron) sheet of poly vinylidine flouride (PVdF) piezoelectric material is bonded to the suspension arm to measure the average induced strain. A further PVdF sensor was used to measure the edge displacement of the disk due to disk bending. The sensor used was in a cantilever configuration, with one end rigidly bonded to the drive chassis in a manner that pre-tensions the cantilever against the disk. Any movement of the disk would change the strain induced in the cantilever.

    CD-ROM is remarked as an epoch-making medium because of its advantages such as large capacity, compact size, mass reproducibility, read only memory and cost performance ratio. Some of big dictionaries and online databases have been converted to CD-ROM versions so far, however, information of publication or machine parts are converted recently. Moreover various CD-ROM-aided products such as support system for R&D, decision making and so on are being turned out. Still there remain many problems on sophisticated utilization of CD-ROM and distributive machinery of information. Author reviews this mini-series and describes the prospects of development of CD-ROM.

    1994-12-31

    Networks are hot and CD-ROM is also hot, but how do they mix? CD-ROM is a relatively inexpensive medium for storing and delivering information, and increasingly, users are connected to networks. But the technologies have developed separately, and there are obstacles to their integration. Drawing on their experience networking CD-ROMs at Oak Ridge National Laboratory, the authors discuss CD-ROM`s strengths and weaknesses as a technology for delivering information to the desktop. CD-ROM networking solutions are LAN-based, not ``open systems.`` Despite this limitation, due to the large number of information resources available on CD-ROM and the relative ease of installing and maintaining databases on CD-ROM, CD-ROMs remain an essential piece of the electronic information puzzle.

    Full Text Available Following on from the impressive development of the new HSBC Money Gallery in 1997, the British Museum has launched into the world of electronic publishing with the World of Money, an "interactive exploration of money worldwide from ancient times to the present day". Intended for ages ten to adult, the CD promises "a mine of information about the use, form, history and importance of money around the globe", and "fun and information for all the family". Reviewing in a Mac-unfriendly environment, I have been able to run the CD only on a PC. On a 166Mhz MMX with 32Mb RAM and a 12x CD it runs impressively quickly, with no more than two or three seconds of the "loading new page" display when switching between different parts of the program. Minimum requirements are listed as a 486 with 8Mb RAM, 40Mb free hard disk space, Windows 3.11 or Windows 95, 4x CD drive, 1Mb 256 colours graphics card, 16-bit Sound Blaster compatible sound card, and a VGA monitor. Minimum requirements for the Mac are listed as System 7, 603e processor, 16Mb RAM, 40MB free hard disk space, 6x CD drive, 1Mb video card and Apple monitor or Multisync with adaptor. The CD opens with an image of the British Museum portico, through which we are taken into the foyer, complete with the sound effects of massed ranks of tourists. We have four options available on a lectern, or by turning left, right or going upstairs: History of Money, Information Centre, Activities, and Options.

  15. Computer Based Radiation Protection- A New Cd-Rom

    Energy Technology Data Exchange (ETDEWEB)

    Geringer, T.; Bammer, M.; Ablber, M.

    2004-07-01

    Within the next few years, there'll be a lot of new challenges required from radiation protection. According to EU regulation[1] and the new austrian radiation protection law [2] regular additional training are requested. Patients protection in diagnostic and therapeutic usage of ionising radiation gains also more and more importance.[3] Not really surprisingly, the general population is definitely highly aware of the risks coming with the usage of radionuclides and x-rays in medicine. Furthermore, the nuclear power plant in Temelin, near the austrian border initiated a lively discussion about risks, necessity and use of ionising radiation in medicine and industry. It turned out to be a really hard job handling these topics in public. A brilliant didactics based on independent information and viewpoints was required. ARC Seibersdorf Research GmbH, represented by the department of medical technical applications and the radiation protection academy, developed an interactive CD-ROM covering several applications: Basics on radiation protection for medical and technical personnel ; preparation for a radiation protection training. Repetition of the main topics for graduates of a radiation protection training. Basics on radiation protection and emergency management for medical staff as well as for the general public. (Author)

  18. Use of CD-ROM-based tool for analyzing contouring variations in involved-field radiotherapy for Stage III NSCLC

    International Nuclear Information System (INIS)

    Background: Interclinician variability in defining target volumes is a problem in conformal radiotherapy. A CD-ROM-based contouring tool was used to conduct a dummy run in an international trial of involved-field chemoradiotherapy for Stage III non-small-cell lung cancer. Methods and Materials: The CT scan of an eligible patient was installed on an 'auto-run' CD-ROM incorporating a contouring program based on ImageJ for Windows, which runs on any personal computer equipped with a CD-ROM drive. This tool was initially piloted at four academic centers and was subsequently mailed, together with all relevant clinical, radiologic, and positron emission tomography findings, to all participating centers in the international trial. Clinicians were instructed to contour separate gross tumor volumes (GTVs) for the tumor and two enlarged nodes and a clinical target volume for the hilus. A reference 'consensus' target volume for each target was jointly generated by three other clinicians. Results: The data received from the four academic centers and 16 study participants were suitable for analysis. Data from one center was unsuitable for detailed analysis because the target volumes were contoured at 1.2-cm intervals. GTVs were available for a total of 21 tumors and 19 nodes, and 15 hilar clinical target volumes were available. The mean GTV of the primary tumor was 13.6 cm3 (SD, 5.2; median, 12.3; range, 8.3-26.9). The variation in the center of the mass relative to the mean center of the mass in the left-right, ventrodorsal, and craniocaudal axes was 1.5, 0.4, and 1.0 mm, respectively. The largest volume variation was observed for the right hilar clinical target volume (mean, 33.7 cm3; SD, 31.2; median, 20.3; range, 4.8-109.9). Smaller variations were observed for the subcarinal node (mean, GTV, 1.9 cm3; SD, 1.2; median, 1.7; range, 0.5-5.3), except caudally where the node was difficult to distinguish from the pericardium. The 'consensus' volumes for all targets were generally

    Eaton, K A; Reynolds, P A; Cox, M J

    2008-02-23

    In many ways the CD-ROM was the first digital teaching aid, the precursor of what was to develop into e-learning. Launched in the mid-1980s, its first educational application was as a storage medium for reference material. Since then the list of its uses has grown as has its storage capacity, ability to hold data in different formats - text, audio image and video - and its interactive properties have allowed developers to produce discs which enhance both the processes and enjoyment of teaching and learning. In this article the stages involved in production of an educational CD-ROM, typical content and the benefits are considered, prior to a review of a number discs that have been used in dental education. The varied titles reveal how versatile CD-ROMs can be. They range from a course showing students the importance of good patient communications and how to achieve them, to an in-depth exposition in the 'Head and Neck Anatomy' disc, a subject important not just for dentistry, but for other medical disciplines as well. The last section of this article considers a study undertaken amongst its students by the Open University, which investigated the effectiveness of CD-ROM in education. In conclusion, it can be said that although the CD-ROM format is a versatile, popular and valuable aid, with the emergence of DVD it may soon be seen as 'old technology' and replaced by the newer format.

    2002-01-01

    I and the other members of the team Celestial Generation dedicate this interactive CD-ROM to our Physics, Astronomy, Biology and English teachers. The members of the team that created the project are Rosen Ralev, Nadezhda Radeva, Iliyan Darganov and Yana Radeva from Technical University of Sofia, the English High schools - Varna, Technical University of Varna and Connecticut College. The leader of the project is Mrs. Veselka Radeva - an astronomer from the Astronomical Observatory in Varna. The main idea of the project " The Living Universe" is that water is a cradle of life in the Universe. As water so abundant in the Universe, life. The project has 4 main themes, combining knowledge from the fields of Biology and Astronomy, one Gallery with our photographs and one amusing theme with interesting and curious facts about life on the Earth and in the Universe. The statistics of our project is: 152 pages and 425 pictures. Over 2/3 from the pictures are ours and we used the rest of them with the kind permission of their authors.The theme Living Water starts with a lyric poem by Petya Dubarova. In the first under-theme- "Water-the cradle of life" introduce you graphics of the structure of the water molecule and its important biological properties. The thesis continues following out the origin and development of life in the oceans on our planet. The next to the last under-theme - sensitive life in water is devoted to dolphins. The third under-theme is " Water in the Universe". Here two of the themes show results from the observations with the space telescope Submillimeter Wave Astronomy Satellite, that found water steams in the interstellar space and around a star in the constellation Leo ( it is supposed that this is a huge comet cloud). This third theme is the most extensive one in this section- it examines the possibility of water being available on each planet in the Solar system: Mercury-most likely there is ice on the polar areas that are the coolest .On Venus it

    Data from the Einstein Observatory imaging proportional counter (IPC) and high resolution imager (HRI) were released on several CD-ROM sets. The sets released so far include pointed IPC and HRI observations in both simple image and detailed photon event list format, as well as the IPC slew survey. With the data on these CD-ROMS's the user can perform spatial analysis (e.g., surface brightness distributions), spectral analysis (with the IPC event lists), and timing analysis (with the IPC and HRI event lists). The next CD-ROM set will contain IPC unscreened data, allowing the user to perform custom screening to recover, for instance, data during times of lost aspect data or high particle background rates.

    Various kinds of paper dictionaries cannot satisfy the productive needs of EFL/ESL learners. With this in mind, McAlp-ine and Myles designed a new type of monolingual electronic dictionary. Coincidentally, the fourth edition of the Longman Dic-tionary of Contemporary English (LDOCE) (Summers 2003) was published with a supporting CD-ROM in 2003. The per-ceived guiding principle of the CD-ROM design was remarkably similar to that of McAlpine and Myles ’design. It can be as-sumed that the CD-ROM will provide EFL/ESL learners with strong support in their writing.

    Full Text Available The main purpose of the study is to find out the availability and utilization level of CDROM databases in IIT Kharagpur library. A well structured questionnaire was administered to the users of the IITK to collect data regarding the utilization of CD-ROM databases. The study reveals that most of the users consult CD- ROM databases not only for updating their knowledge but also for collecting relevant information for the study and research purposes. A majority of the users have become aware of CD-ROM databases through library staff, discussions with colleagues and from observation. The most popular search method for searching CD-ROM databases is keyword followed by Boolean operators and phrases.

  16. Evaluating CD-ROM versions of the MEDLINE database: a checklist.

    Hewison, N S

    1989-10-01

    The emergence of CD-ROM (compact disc/read-only memory) versions of the MEDLINE database requires experienced MEDLINE searchers to examine assumptions about searching MEDLINE, since some expectations may not be fulfilled by this new technology. When applied to a particular CD-ROM MEDLINE product, the evaluation procedure involves testing assumptions concerning database contents; mechanics of searching; display, print, and download capabilities; and user-friendly features. The extent to which a CD-ROM product preserves and exploits important MEDLINE strengths should be assessed, e.g., the MeSH controlled vocabulary, the designation of major and minor MeSH emphasis, and the use of subheadings. Search software characteristics that affect ease of searching and quality of results also need to be examined, e.g., the ability to truncate search terms and the order of precedence in which Boolean operators are evaluated. A checklist to assist in the evaluation process is presented, including search examples for use in testing search functions. PMID:2676046

    The National Educators' Workshop (NEW:Update) series of workshops has been in existence since 1986. These annual workshops focus on technical updates and laboratory experiments for materials science, engineering and technology, involving new and traditional content in the field. Scores of educators and industrial and national laboratory personnel have contributed many useful experiments and demonstrations which were then published as NASA Conference Proceedings. This "out poring of riches" creates an ever-expanding shelf of valuable teaching tools for college, university, community college and advanced high school instruction. Now, more than 400 experiments and demonstrations, representing the first thirteen years of NEW:Updates have been selected and published on a CD-ROM, through the collaboration of this national network of materials educators, engineers, and scientists. The CD-ROM examined in this document utilizes the popular Adobe Acrobat Reader format and operates on most popular computer platforms. This presentation provides an overview of the second edition of Experiments in Materials Science, Engineering and Technology (EMSET2) CD-ROM, ISBN 0-13-030534-0.

    Full Text Available 'Beowulf? .... that's by Seamus Heaney. Sorry we're sold out.' It is hardly surprising that Heaney's new translation of Beowulf should seem like a completely new work. It has been a very long time since Grendel's mother was on the archaeology reading list, let alone among the best sellers. The new translation has a parallel, less popular but in many respects more interesting, product from the British Library in the shape of Electronic Beowulf, a CD-Rom (or two which provides virtual access to the medieval manuscript itself.

  1. Effects of Using Human Patient Simulator (HPS versus a CD-ROM on Cognition and Critical Thinking

    Directory of Open Access Journals (Sweden)

    Don Johnson, PhD

    2008-01-01

    Full Text Available Background: Very little prospective randomized experimental research exists on the use of simulation as a teaching method, and no studies have compared the two strategies of using the HPS and a CD-ROM. In addition, no researchers have investigated the effects of simulation on various levels of cognition, specifically lower-level and higher-level cognition or critical thinking.Objectives: A prospective pretest-posttest experimental mixed design (within and between was used to determine if there were statistically significant differences in HPS and CD-ROM educational strategies in lower-level, higher-level cognition and critical thinking.Results: A repeated measures multivariate analysis of variance (RMANOVA with LSD post-hoc tests were used to analyze the data. There were no significant differences between the HPS and CD-ROM groups on lower-level cognition scores. The HPS group did significantly better than the CD-ROM group on higher-level cognition and critical thinking scores.Conclusion: This study demonstrated that the choice of teaching strategies for lower-level cognition does not make a statistically significant difference in outcome. However, the HPS is superior to using CD-ROM and should be considered as the choice in teaching.

    2000-04-15

    Until recently, anatomists had no doubt that the teaching of anatomy had to include cadaver dissection. However, due to a changing academic environment as well as challenged financial institutional resources, computer-assisted instruction was introduced into medical curriculum in an attempt to reduce the cost and the time committed to cadaver dissection. Computer-assisted instruction included locally created or commercially available anatomy software, Internet sites, and databases of digital images of cadaveric structures such as the Virtual Human Project. However, until now, bandwidth limitations have not allowed effective visualization in real-time over the Internet of recorded videos or 3D animations reconstructed from a database. We describe how to successfully link and display large video clips stored on a CD-ROM in support of lectures saved in HTML format on the Internet. This process, described in its totality, allows students to access audiovisual files on a CD-ROM through the Internet, from any location, with either Macintosh or Windows computers, using the Netscape browser. This process allowed us to circumvent one of the most significant limitations of the computer-assisted instruction on the Internet by delivering full audio and visual information on demand, as it would happen in a traditional classroom.

    1998-12-01

    Construction of a handy spectroscope using a compact disk (CD) or a CD-ROM and its application to the observation of emission and absorption spectra are described. Using this simple cardboard-made spectroscope, one can readily observe line emission spectra of fluorescent lamps, gas discharge tubes, etc. The spectroscope is also used to observe the absorption spectra of colored solutions; the absorption bands are observed as distinct black bands on the rainbow-colored continuous spectrum of an incandescent lamp. The results for the aqueous solution of potassium permanganate, the methanol and ethanol solutions of cobalt chloride, and Fe(III)-thiocyanate complex are described. These results clearly show the general rule that a colored solution absorbs the complementary color of the color of the solution. Thus, the CD-ROM spectroscope is a useful tool in primary and secondary schools to teach what color is and what spectra are. Furthermore, it can be used effectively in introductory courses in colleges and universities to teach that spectra are really beautiful natural phenomena which can be observed simply.

    Full Text Available The CD-ROM "Voice Assessment: Speech-Language Pathology and Audiology & Medicine" was developed as a teaching tool for people interested in the production of the spoken or sung human voice. Its content comprises several subjects concerning the anatomy and physiology of spoken and sung voice. A careful assessment becomes necessary in order to ensure the effectiveness of teaching and learning educational materials, whether related to education or health, within the proposal of education mediated by technology. OBJECTIVE: This study aimed to evaluate the efficacy of the Virtual Man Project's CD-ROM "Voice Assessment: Speech-Language Pathology and Audiology & Medicine", as a self-learning material, in two different populations: Speech-Language Pathology and Audiology students and Lyrical Singing students. The participants were instructed to study the CD-ROM during 1 month and answer two questionnaires: one before and another one after studying the CD-ROM. The quantitative results were compared statistically by the Student's t-test at a significance level of 5%. RESULTS: Seventeen out of the 28 students who completed the study, were Speech-Language Pathology and Audiology students, while 11 were Lyrical Singing students (dropout rate of 44%. Comparison of the answers to the questionnaires before and after studying the CD-ROM showed a statistically significant increase of the scores for the questionnaire applied after studying the CD-ROM for both Speech-Language Pathology and Audiology and Lyrical Singing students, with p<0.001 and p<0.004, respectively. There was also a statistically significant difference in all topics of this questionnaire for both groups of students. CONCLUSION: The results concerning the evaluation of the Speech-Language Pathology and Audiology and Lyrical Singing students' knowledge before and after learning from the CD-ROM allowed concluding that the participants made significant improvement in their knowledge of the proposed

  12. Experience teaching CD-ROM-based course on CANDU nuclear-power-plant systems and operation

    International Nuclear Information System (INIS)

    This paper presents personal experience garnered from teaching a CD-ROM-based course on CANDU Power-Plant Systems and Operation. This course was originally developed by Prof. G.T. Bereznai as research in distance-learning techniques when he was directing the Thai-Canadian Human Resources Development Project at Chulalongkorn University in Bangkok. The course has been offered in a number of universities, including McMaster University and the University of Ontario Institute of Technology. All the course material, including lectures, assignments, and a simulator, is provided on a CD-ROM. Lectures include a spoken soundtrack covering the material. The class often includes both undergraduate and graduate students. I found that most students appreciate having the material on electronic format, which they can view and review at will and on their own time. Students find this course quite intensive - it covers all major systems in the CANDU reactor and power plant in detail. A very important component of the course is the simulator, which teaches students how systems operate in normal operation, in power manoeuvres, and during process-system malfunctions. Effort in absorbing the material and performing assignments can often exceed 10 hours per week. Some of the simulator assignments involve tricky manoeuvres, requiring several tries to achieve the expected result. Some assignments may take several hours, especially if the manoeuvres requiring repetition take 30 minutes or more in real time. I found that some instruction in the basic theory of reactor physics and systems is appreciated by students. A few possible enhancements to the simulator model were identified. Graduate students taking the course are required to do an additional project; I assigned an investigation of the effects of xenon-concentration changes during 1 week of load cycling. In summary, this course provides to students the opportunity to learn a great deal about the workings of CANDU-plant systems. (author)

    As part of this project a large volume of ionospheric satellite insitu data from the sixties, seventies and early eighties were made accessible online in ASCII format for public use. This includes 14 data sets from the BE-B, Alouette 2, DME-A, AE-B, ISIS-1, ISIS-2, OGO-6, DE-2, AEROS-A, AE-C, AE-D, AE-E, and Hinotori satellites. The original data existed in various machine-specific, highly compressed, binary encoding on 7-, or 9-track magnetic tapes. The data were decoded and converted to a common ASCII data format, solar and magnetic indices were added, and some quality control measures were taken. The original intent of producing CD-ROMs with these data was overtaken by the rapid development of the Internet. Most users now prefer to obtain the data directly online and greatly value WWW-interfaces to browse, plot and subset the data. Accordingly the data were made available online on the anonymous ftp site of NASA's National Space Science Data Center (NSSDC) at ftp://nssdcftp.gsfc.nasa.gov/spacecraft data/ and on NSSDC's ATMOWeb (http://nssdc.gsfc.nasa.gov/atmoweb/), a WWW-interface for plotting, subsetting, and downloading the data. Several new features were implemented into ATMOWeb as part of this project including a filtering and scatter plot capability. The availability of this new database and WWW system was announced through several electronic mailer (AGU, CEDAR, IRI, etc) and through talks and posters during scientific meetings.

  14. Quality Management Audits in Nuclear Medicine Practices. 2. Ed. Companion CD-ROM

    International Nuclear Information System (INIS)

    Quality management systems are essential and should be maintained with the intent to continuously improve effectiveness and efficiency, enabling nuclear medicine to achieve the expectations of its quality policy, satisfy its customers and improve professionalism. The quality management (QM) audit methodology in nuclear medicine practice, introduced in this publication, is designed to be applied to a variety of economic circumstances. A key outcome is a culture of reviewing all processes of the clinical service for continuous improvement in nuclear medicine practice. Regular quality audits and assessments are vital for modern nuclear medicine services. More importantly, the entire QM and audit process has to be systematic, patient oriented and outcome based. The management of services should also take into account the diversity of nuclear medicine services around the world and multidisciplinary contributions. The latter include clinical, technical, radiopharmaceutical, medical physics and radiation safety procedures. This companion CD-ROM is attached to the printed STI/PUB/1683 and contains the full-text of STI/PUB/1683 as well as checklists in PDF and Excel format and a table with the contents of a standardized audit report

    The CD-ROM technology allows the production of multimedia works which costs far less than books do. The creation of Internet and the servers World Wide Web has the advantage of distributing those works world wide, without the difficulties and the delays related to books and magazines distribution. The Teachers' Council of Radiology of France (CERF) and the French Society of Radiology (SFR) have opted to use these new media and these information highways to spread a part of their radiology teaching work. Iconocerf is a software program which allows to create, store, read and to exchange digitized radiological cases. It's available free of charge, within the CERF and SFR. The CD-ROMs Iconocerf-Medimag contain 3,500 radiological files with 15,000 images, previously on the videodisc Medimag. The Server of the French Radiology is a W3 server which includes: the CERF directory, a guide for the teachers, the research workers and the students in Radiology and Medical Imaging. It also contains the teaching works on Radiology, and some Iconocerf clinical cases translated onto HTML. The aim of this project is to create an evaluation system for radiology. By using key words, this system allows to consult: radiological clinical cases, located on the server or on CD-ROMs; reference texts; and to have access to the experts' addresses to be able to send them eventually a difficult case through electronic mail.

  19. NASA Space Mechanisms Handbook and Reference Guide Expanded Into CD-ROM Set

    Science.gov (United States)

    Fusaro, Robert L.

    2002-01-01

    Several NASA missions suffered failures and anomalies due to problems in applying space mechanisms technology to specific projects. Research shows that engineers often lack either adequate knowledge of mechanism design or sufficient understanding of how mechanisms affect sensitive systems. The Space Mechanisms Project conducted a Lessons Learned study and published a Space Mechanisms Handbook to help space industry engineers avoid recurring design, qualification, and application problems. The Space Mechanisms Handbook written at the NASA Glenn Research Center details the state-of-the-art in space mechanisms design as of 1998. NASA's objective in developing this Space Mechanisms Handbook was to provide readily accessible information on such areas as space mechanisms design, mechanical component availability and use, testing and qualification of mechanical systems, and a listing of worldwide space mechanisms experts and testing facilities in the United States. This handbook has been expanded into a two-volume CD-ROM set in an Adobe Acrobat format.

    Full Text Available In early February 1805 a small fleet of East Indiamen accompanied by the frigate Weymouth set sail from Portsmouth heading first for Bengal and ultimately for China. However, barely had the voyage began when, following bad weather and confusion, one of the boats, the Earl of Abergavenny, struck the Shambles bank just off Portland Bill. Although the crew managed to free it, it was so badly damaged it sank while trying to make for the safety of Weymouth. Over 250 crew and passengers drowned. The wreck has until now been best known for causing the death of John Wordsworth, the ship's commander and brother of the poet William Wordsworth. This excellent CD report of archaeological investigations on the wreck site carried out since 1980 by the Weymouth Underwater Archaeological Group (WUAG brings us the full picture of the events leading up to the wreck, and a record of the remains found by the team of divers (Fig.1. The complex campaigns of diving have been carried out alongside extensive documentary and historical work. The huge amount of data created by this project has inevitably led to challenges for the WUAG regarding its publication (Cumming 2002. The decision to publish via a CD-ROM has allowed very large quantities of data and discussion to be published. The current version of the CD contains over 100,000 words of text, 1560 files and over 1000 illustrations (JPEGS. All for the grand price of 10 GBP. The volume can be browsed using a commercially available browser but is also supplied as compiled file using Web Compiler, which has the advantage of a search facility.

    Full Text Available Introduction Research indicates that low fruit and vegetable intake is a risk factor for many chronic diseases. Despite large-scale education campaigns, the great majority of Americans do not consume recommended levels. We tested the ability of a single brief interactive experience of the Little by Little CD-ROM to increase fruit and vegetable intake in low-income women. Methods A randomized placebo-controlled, parallel-group trial included 481 low-income, female participants: mean age 50.1 years, 48.4% African American, 51.6% non-Hispanic white, and 92.5% below 185% of the federally designated poverty level. Participants received one of three conditions: 1 a one-time experience with the Little by Little CD-ROM, 2 the Little by Little CD-ROM plus two reminder telephone calls, or 3 a stress management CD-ROM (control condition. We assessed baseline and follow-up dietary intake with a modified 24-hour recall. Results Two months after the one-time experience with the CD-ROMs, both intervention groups reported significantly higher intakes of fruits and vegetables than the control group. The Little by Little group with reminder calls increased daily intake by 1.32 fruits/vegetables, an 86% greater increase than the control group (P = .016. The Little by Little group without reminder calls increased daily intake by 1.20 fruits/vegetables, a 69% greater increase than the control group (P = .052. Significantly greater movement in Stage of Readiness for Change also occurred in the Little by Little groups compared with the control group. Conclusion The Little by Little CD-ROM may be useful in public health and clinical situations to increase fruit and vegetable intake.

    The Smithsonian Institution's Global Volcanism Program is nearing completion of an interactive CD-ROM, the Volcanoes of México. This CD is the second in a series sponsored by the U.S. Department of Energy Office of Geothermal Technologies to collate Smithsonian data on Quaternary volcanism as a resource for the geothermal community. It also has utility for those concerned with volcanic hazard and risk mitgation as well as an educational tool for those interested in Mexican volcanism. We acknowledge the significant contributions of many Mexican volcanologists to the eruption reports, data, and images contained in this CD, in particular those contributions of the Centro Nacional de Prevencion de Desastres (CENAPRED), the Colima Volcano Observatory of the University of Colima, and the Universidad Nacional Autónoma de México (UNAM). The Volcanoes of México CD has a format similar to that of an earlier Smithsonian CD, the Volcanoes of Indonesia, but also shows Pleistocene volcanic centers and additional data on geothermal sites. A clickable map of México shows both Holocene and Pleistocene volcanic centers and provides access to individual pages on 67 volcanoes ranging from Cerro Prieto in Baja California to Tacaná on the Guatemalan border. These include geographic and geologic data on individual volcanoes (as well as a brief paragraph summarizing the geologic history) along with tabular eruption chronologies, eruptive characteristics, and eruptive volumes, when known. Volcano data are accessible from both geographical and alphabetical searches. A major component of the CD is more than 400 digitized images illustrating the morphology of volcanic centers and eruption processes and deposits, providing a dramatic visual primer to the country's volcanoes. Images of specific eruptions can be directly linked to from the eruption chronology tables. The Volcanoes of México CD includes monthly reports and associated figures and tables cataloging volcanic activity in M

  4. Arctic Connections, an Interactive CD-ROM Program for Middle School Science

    Elias, S. A.

    2003-12-01

    In this project we developed an interactive CD-ROM program for middle school students, accompanied by an interactive web site. The project was sponsored by a grant from the NSF ESIE Instructional Materials Development program. One of the major goals of this project was to involve middle school students in inquiry-based science education, using topics that are of interest to students in Arctic communities. Native Alaskan students have traditionally done poorly in science at the secondary level, and few have gone on to major in the sciences in college or to pursue scientific careers. Part of the problem is a perceived dichotomy between science and traditional Native ways of knowing about the natural world. Hence some students reject the scientific method as being foreign to their native culture. Our goal was to help bridge this cultural barrier, and to demonstrate to native students that the scientific method is not antithetical to their traditional way of life. The program uses story modules that discuss both scientific and Native ways of understanding, through the use of action-adventure stories and brief learning modules. The aim was to show students the relevance of science to their daily lives, and to convince them that scientific methods are a vital tool in solving major problems in arctic communities. Each action-adventure story contains a series of problems that the program user must solve through interactive participation, in order for the story to progress. The interactive elements include answering quiz questions correctly, measuring pH by comparing litmus paper colors, measuring archaeological artifact dimensions, finding the location of fossil bones in a photograph, and correctly identifying photographs of whale species, arctic plants, and fish. The stories contain a mixture of live-action film sequences and voice-over sketch art story boards. The ten modules include such topics as arctic flora and fauna (including terrestrial and sea mammals), arctic

    expect. This is an issue that is in the teacher's hands; the package is flexible enough to accommodate a wide range of learning aims. Audio clips are brief and to the point, with both female and male speakers. The commentary goes beyond the descriptive, raising interesting questions and issues and setting challenges for the user. The optional screen text is pitched at A-level. Video clips can be viewed at full screen, which is a big improvement over the first edition. There are some new clips and a few omissions from the first edition; further CDs of movie data are planned. Clips may be played forwards or backwards at various speeds using a scroll bar. This allows close control and analysis, which is useful for critical events in which changes are rapid, such as collisions. Printing of data and graphs is straightforward and the results are clear. Unlike the first edition, Multimedia Motion II only gives direct support to graphs with time as the abscissa. For graphs such as v(x) versus v(y), however, it is a simple matter to save the data directly into Excel or another spreadsheet. I encountered only one snag in using the CD: if I forgot to save my data before moving to a new clip I could not recover it. This failing could be mine, but I did try hard. The Teacher's Guide contains photocopiable worksheets and detailed discussion and graphs of the video clips. For each clip there is a section of `useful data and formulae'. The guide is not a necessity for using the CD-ROM but it would be a very handy A-level teaching resource, allowing the option of independent use by students. It is accompanied by a floppy disc containing sets of experimental data for the video clips, a useful option for quick demonstrations. In addition, the guide explains the interesting and creative option of making your own movie sequences from videotape, though access to a video card would be needed to do this. Imagine the motivational value of students recording themselves playing various sports, or

    Full Text Available Distance education has emerged to minimize the anxiety of many professionals who need to update their knowledge, but do not have the time and opportunity to travel to educational centers. Objectives: To describe the development of a CD-ROM to provide distance continuing education to basic school teachers that addresses issues related to written language. Material and Methods: Previously, a script was developed with themes related to the acquisition and development of written language. Subsequently, a technical team transformed the texts in multimedia language. Results: The titles of each content area addressed are available on buttons and links. The files can be viewed in a linear sequence, allowing the teacher to start learning at the desired moment and go straight to the file that he or she wants to access. Videos that show practical applications of the concepts available in text are included. Conclusions: Brazil is a developing country. The use of technologies for education reduces cultural isolation among education professionals. It is necessary to focus on making teaching materials for distance education. In order to provide an effective learning environment, the learners reality should be considered. A multidisciplinary team should prepare the materials. The development of educational material for distance education on the acquisition and development of written language seems not only appropriate, but also warranted to provide professional growth opportunity for teachers who need time flexibility and/or live far away from academic centers.

    The environment where everyday activities are developed, these should be appropriate and the individual who will execute them, for greater efficiency of their work and even if you feel safe, comfortable and satisfied when interacting with that space, expending less energy to this interaction. Given this context, this study aims to structure a software with the results obtained in the field, from anthropometric measure to subsidize the furniture industry in manufacturing of furniture, definition work situations, considering the different anthropometric measurements made between 2001 and 2010, using data from this sample of adults aged 18 to 65 years old and children between 6 and 11 years old. It was convenient to make the software with a site, only instead of staying on the Web has been recorded on CD Rom. Tests with the prototype allow navigation through the structure of the software. The data needed to implement the remaining modules were also raised. Issues related to system layout and usability of the interface also were not considered, because it is an initial prototype.

    International Nuclear Information System (INIS)

    The two Numerical Recipes books are marvellous. The principal book, The Art of Scientific Computing, contains program listings for almost every conceivable requirement, and it also contains a well written discussion of the algorithms and the numerical methods involved. The Example Book provides a complete driving program, with helpful notes, for nearly all the routines in the principal book. The first edition of Numerical Recipes: The Art of Scientific Computing was published in 1986 in two versions, one with programs in Fortran, the other with programs in Pascal. There were subsequent versions with programs in BASIC and in C. The second, enlarged edition was published in 1992, again in two versions, one with programs in Fortran (NR(F)), the other with programs in C (NR(C)). In 1996 the authors produced Numerical Recipes in Fortran 90: The Art of Parallel Scientific Computing as a supplement, called Volume 2, with the original (Fortran) version referred to as Volume 1. Numerical Recipes in C++ (NR(C++)) is another version of the 1992 edition. The numerical recipes are also available on a CD ROM: if you want to use any of the recipes, I would strongly advise you to buy the CD ROM. The CD ROM contains the programs in all the languages. When the first edition was published I bought it, and have also bought copies of the other editions as they have appeared. Anyone involved in scientific computing ought to have a copy of at least one version of Numerical Recipes, and there also ought to be copies in every library. If you already have NR(F), should you buy the NR(C++) and, if not, which version should you buy? In the preface to Volume 2 of NR(F), the authors say 'C and C++ programmers have not been far from our minds as we have written this volume, and we think that you will find that time spent in absorbing its principal lessons will be amply repaid in the future as C and C++ eventually develop standard parallel extensions'.

    One of the major challenges for faculty teaching general chemistry is how to encourage students to practice solving problems. We know that for students to develop chemical intuition and problem-solving skills, they must "get their hands dirty" as they decipher and unravel problems inherent to our discipline. One tool that I've used since its release in 1996 is the ChemSkill Builder, an electronic homework package. The latest version, ChemSkill Builder (CSB) 2000, version 6.1, is an excellent, effective integration of teaching and testing most quantitative and conceptual learning objectives in an interactive way. It is inexpensive and easy to use for both students and faculty. The CSB 2000 package of personalized problem sets, specifically designed to complement most general chemistry courses, is a program on CD-ROM for PC Windows users (3.1, 95, or 98), with more than 1500 questions and a 3 1/2-in. record-management disk. There is a separate grade-management disk for the instructor. It has 24 gradable chapters, each with 5 or 6 sections, plus two new chapters that are not graded: Polymer Chemistry and an Appendix of Chemical Skills. Each section begins with a short review of the topic and many have interactive explanations. If students miss an answer, they are given a second chance for 70% credit. If they still miss, the worked-out solution is presented in detail. Students can work each section as many times as they wish to improve their scores. Periodically, the students download their data directly into a PC set up by the instructor. The data can be easily converted into an ASCII file and merged with a spreadsheet. The use of CD-ROM solves the sporadic problems associated with previous versions on 3 1/2-in. disks: software glitches, failed disks, and system incompatibilities. The quality and number of graphics and interactive exercises are much improved in this latest version. I particularly enjoyed the interactive explanations of significant figures and

    "Genetics and Major Psychiatric Disorders: A Program for Genetic Counselors" provides an introduction to psychiatric genetics, with a focus on the genetics of common complex disease, for genetics professionals. The program is available as a CD-ROM and an online educational resource. The on-line version requires a direct internet connection. Each educational module begins with an interactive case study that raises significant issues addressed in each module. In addition, case studies provided throughout the educational materials support teaching of major concepts. Incorporated throughout the content are expert video clips, video clips from individuals affected by psychiatric illness, and optional "learn more" materials that offer greater depth about a particular topic. The structure of the CD-ROM permits self-navigation, but we have suggested a sequence that allows materials to build upon each other. At any point in the materials, users may pause and look up terms in the glossary or review the DSM-IV criteria for selected psychiatric disorders. A detailed site map is available for those who choose to self navigate through the content.

    2003-01-01

    Within the framework of an informational programme on the risks of asthma associated with certain occupations (hairdresser, carpenter or baker), an interactive CD-ROM was developed for senior students of these professions. Among the schools who benefited from this information, the programme chose three to evaluate. A total of 113 students between the ages of 17 and 20 filled out a questionnaire and participated in a group discussion after the session. All of the students were able even though only 48% regularly use a computer. More than 95% of the participants were satisfied with the content, the academic approach proposed and the interactive support, which is flexible and contains a self-test. The students found the CD-ROM to be a more efficient means of retaining information than classic lectures. As for the evaluation of the knowledge acquired on asthma and the workplace, half of the students said they had considerably increased their knowledge on the illness, while 47% only saw a minor increase. This statement was confirmed through the correlation of scores obtained in the pre- and post-programme exams, whose results show a statistically significant increase in knowledge. Despite the academic value the students gave to this type of learning, the advantage of this kind of pedagogical tool are also to be considered given that is easy for teachers to learn how to use the technology and teach it. Nowadays it is so simple to produce multimedia support for computers, that this method can be easily developed for a target audience and at low cost. PMID:13677041

    Full Text Available The paper gives an overview of a two-years project concerning a major monument of ancient Greek art and presents the interactive, bilingual (English/Hungarian CD-ROM, which is intended to summarize and visualize its final results. The presented project approaches a century-old controversy in a new way by producing a virtual 3D reconstruction of a monumental marble group. Digital models of the statues were produced by scanning the original fragments and by reconstructing them virtually. The virtual model of the pediment surrounding the sculptures was prepared on the basis of the latest architectural studies and afterwards the reconstructed models were inserted in this frame, in order to test the technical feasibility and aesthetic effects the four possible arrangements. The resulting models enable easy and very instructive experimentation, which would be otherwise impossible with the originals and/or very expensive and not very practicable with traditional tools (e.g. real-size plaster models. The complete model can effectively be used to verify the results of earlier or more recent reconstructions presented only in simple drawings. In addition, the 3D models of the individual fragments can be used for further research and for visualization.  The documentary CD-ROM presenting the full background, the methods and the conclusions of the project contains beside a comprehensive text various kinds of supporting documents (images, 3D models, papers, broadcasts, audiovisual material. It is addressed to a mixed audience: a picture gallery, a short documentary movie some other attachments including a selected bibliography is intended for the general public, but scholarly publications, presentations on related problems are also included for specialists interested in certain details.

    International Nuclear Information System (INIS)

    The International Project on Innovative Nuclear Reactors and Fuel Cycles (INPRO) was launched in the year 2000, based on a resolution by the IAEA General Conference (GC(44)/RES/21). INPRO intends to help to ensure that nuclear energy is available in the 21st century in a sustainable manner, and seeks to bring together all interested Member States, both technology holders and technology users, to consider, jointly, actions to achieve desired innovations. INPRO is taking care of the specific needs of developing countries. This IAEA publication is part of Phase 1 of INPRO. It intends to provide an overview on history, present situation and future perspectives of nuclear fuel cycle technologies. While this overview focuses on technical issues, nevertheless, the aspects of economics, environment, and safety and proliferation resistance are important background issues for this study. After a brief description about the INPRO project and an evaluation of existing and future reactor designs the publication covers nuclear fuel cycle issues in detail. It is expected that this documentation will provide IAEA Member States and their nuclear engineers and designers, as well as policy makers with useful information on status and trends of future nuclear fuel cycle technologies. Due to the size of the full report it was decided to attach a CD-ROM in the back of the summary report

    1998-12-01

    Full Text Available Unusually in a review, the first comments need to be directed to the medium of publication itself. This is inevitable, given the decision to produce the Proceedings of the Forli Colloquium on CD-ROM, rather than as a conventional volume. The main advantages of this ought to be the ability to use media other than monochrome graphics (such as colour, video and sound and the availability of hyperlinks, which provide freedom from the serial structure of text. The disadvantages are that reading from a screen can be very tiresome and referencing, in a formal way, is made more difficult by the lack of page numbers etc.

    2000-12-01

    Full Text Available The paper presents the recently-published CR-ROM «The Iberians and their Images». The production of this CDROM has been possible thanks to the DGICYT (Madrid, through a PETRI project involving collaboration between CSIC and the computer company Micronet, SA. The project originated with the traveling exhibition La sociedad ibérica a través de la imagen, the layout of which inspired the structure of the CD-ROM, adapted to this new medium. The project provides complex research on images in the Iberian culture in the context of ancient Mediterranean cultures. From this point of view, it presents a very rich catalogue of over 1500 images of Iberian pre-history stretching from the late Bronze Age to the arrival of the Romans. The main objective has been to create a useful working tool for any specialist in the subject matter and to provide a rich and up-to-date document for any user interested in Iberian culture, of the archaeology, history and religions and myths of the ancient Mediterranean world.Presentamos en este artículo el CD-ROM Los iberos y sus imágenes, de reciente aparición en el mercado, cuya realización ha sido posible gracias a una subvención de la DGICYT, mediante un proyecto PETRI que ha implicado la colaboración entre el CSIC y la empresa informática MICRONET S.A. La génesis y el planteamiento del proyecto parte de la exposición itinerante La sociedad ibérica a través de la imagen, que guía la estructura general del Cd-rom, adaptada al nuevo soporte. Este proyecto plantea una indagación compleja sobre la imagen en la cultura ibérica, en el contexto de las culturas del mediterráneo antiguo. Desde este punto de vista, se ha realizado un riquísimo catálogo con más de 1500 imágenes de la Protohistoria ibérica que cronológicamente van del Bronce Final hasta la romanización. Se ha pretendido elaborar una obra que suponga una herramienta de trabajo para cualquier especialista en la materia y, por otro lado, un rico

    2000-08-01

    Full Text Available In an as yet unpublished paper on computer-assisted visual anthropology, Michael D Fischer and David Zeitlyn [1] describe a 'book model' approach to multimedia, not strictly sequenced, but essentially consisting of a main text with hyperlinks to supporting information. At first glance this CD-ROM appears to conform to this model: a dominant text, in this case a complete digitization of Tim Asch and Napoleon Chagnon's 1974 film The Ax Fight, supplemented with a variety of additional information in the form of still photographs, genealogies of the main participants, maps, diagrams, short essays and transcriptions. In short, a main text plus footnotes and appendixes. If this were so, then Yanomamö Interactive would be a valuable but rather limited product, useful really only to those aquainted with the film who wished to learn a little more about it and its content.

    Harrell, R.

    1996-03-01

    Ongoing refinements in our capabilities to accurately estimate recoverable volumes and future rates of production of oil and gas reserves, was discussed. The four major reserves classification systems which are familiar to reservoir engineers were reviewed. These are: the classification systems established by (1) the U.S. Securities and Exchange Commission (SEC), (2) the Society of Petroleum Engineers (SPE), (3) the World Petroleum Congress (WPC), and (4) the classification used by the former Soviet Union (FSU). All reserve reports should contain specific mention of the classification system used, and provide specific definitions of the reserves categories used in that report. The fallacy of comparing estimates of proven reserves using definitions and pricing assumptions taken from different systems was emphasized. Several recommendations were made for maintaining consistency among evaluations.

    The difference between surface and mineral rights in Alberta was defined. By definition, surface rights give ownership only to the surface of the land and the right to work it. Mineral rights in contrast give ownership and the right to explore and develop or extract minerals beneath the surface. Oil and gas are the most common minerals in Alberta, however, gold silver, uranium and salt are also included under mineral rights, but sand, gravel, clay, marl and peat, are not. Conditions which limit the mineral owner`s right to explore and develop were summarized. Some case studies of appeals to the court regarding mineral and surface rights were presented.

Vol. 1 of 9 of the final report of phase 1 of the International Project on Innovative Nuclear Reactors and Fuel Cycles (INPRO) including a CD-ROM comprising all volumes

    International Nuclear Information System (INIS)

    The International Project on Innovative Nuclear Reactors and Fuel Cycles (INPRO) was initiated in the year 2000, based on a resolution of the IAEA General Conference (GC(44)/RES/21). The main objectives of INPRO are (1) to help to ensure that nuclear energy is available to contribute in fulfilling energy needs in the 21st century in a sustainable manner, (2) to bring together both technology holders and technology users to consider jointly the international and national actions required to achieve desired innovations in nuclear reactors and fuel cycles; and (3) to create a forum to involve all relevant stakeholders that will have an impact on, draw from, and complement the activities of existing institutions, as well as ongoing initiatives at the national and international level. This document follows the guidelines of the INPRO report 'Methodology for the assessment of innovative nuclear reactors and fuel cycles, Report of Phase 1B (first part) of the International Project on Innovative Nuclear Reactors and Fuel Cycles (INPRO)', IAEA-TECDOC-1434 (2004), together with its previous report Guidance for the evaluation for innovative nuclear reactors and fuel cycles, Report of Phase 1A of the International Project on Innovative Nuclear Reactors and Fuel Cycles (INPRO), IAEA-TECDOC-1362 (2003). This INPRO manual is comprised of an overview volume (laid out in this report), and eight additional volumes (available on a CD-ROM attached to the inside back cover of this report) covering the areas of economics (Volume 2), infrastructure (Volume 3), waste management (Volume 4), proliferation resistance (Volume 5), physical protection (Volume 6), environment (Volume 7), safety of reactors (Volume 8), and safety of nuclear fuel cycle facilities (Volume 9). The overview volume sets out the philosophy of INPRO and a general discussion of the INPRO methodology. This overview volume discusses the relationship of INPRO with the UN concept of sustainability to demonstrate how the

  2. Fabrication of Beam-rotating Actuator for Multiple-beam Disk Drive

    Science.gov (United States)

    Kim, Boung Jun; Kim, Soo Hyun; Kwak, Yoon Keun

    2002-05-01

    Current trends in computer and communication industries are towards increasingly higher resolution images and video processing techniques. However, such sophisticated processing tasks require massive storage systems such as a compact disk read only memory (CD-ROM) and digital versatile disc (DVD). Current demands in the development of such systems are higher data density storage media and an improved data transfer rate. The latter is discussed in this paper. A multiple-beam optical disk drive is presented as a method for improving the effective data transfer rate by increasing the beam spot number formed on an optical disk. The beam-rotating actuator is necessary for positioning the multiple-beam onto more than one track. Ray tracing was also employed for the real system setup. The beam-rotating actuator is made up of piezoelectric material, a high-stiffness wire hinge and a dove prism. The actuator has an approximately 1 kHz resonance frequency and a suitable operational range. The dynamic equation for the actuator is derived for the control of the real system.

  8. Methodology for Safety Assessment Applied to Predisposal Waste Management. Report of the Results of the International Project on Safety Assessment Driving Radioactive Waste Management Solutions (SADRWMS) 2004–2010)

    International Nuclear Information System (INIS)

    Report of the Results of the International Project on Safety Assessment Driving Radioactive Waste Management Solutions (SADRWMS) (2004–2010) The IAEA’s progamme on Safety Assessment Driving Radioactive Waste Management Solutions (SADRWMS) focused on approaches and mechanisms for application of safety assessment methodologies for the predisposal management of radioactive waste. The initial outcome of the SADRWMS Project was achieved through the development of flowcharts, which have since been incorporated into IAEA Safety Standards Series No. GSG-3, Safety Case and Safety Assessment for Predisposal Management of Radioactive Waste. In 2005, an initial specification was developed for the Safety Assessment Framework (SAFRAN) software tool to apply the SADRWMS flowcharts. In 2008, an in-depth application of the SAFRAN tool and the SADRWMS methodology was carried out on the predisposal management facilities of the Thailand Institute of Nuclear Technology Radioactive Waste Management Centre (TINT Facility). This publication summarizes the content and outcomes of the SADRWMS programme. The Chairman’s Report of the SADRWMS Project and the Report of the TINT test case are provided on the CD-ROM which accompanies this report

  10. Status and future of the direct sales market; CD-ROM ed.

    Energy Technology Data Exchange (ETDEWEB)

    DuMaresq, P.R.

    1996-05-01

    Three topics of interest concerning the direct purchase of natural gas, were discussed. The three topics were: (1) the Ontario market, past, present and future, along with an analysis of market segmentation, (2) Ontario local distribution companies (LDC) separation, or separating the merchant role from the distribution role, and (3) the status of direct purchase in Alberta. Changes in the natural gas market since deregulation in 1985, were also reviewed. It was noted that today, only a handful of agents, brokers and marketers of natural gas are vying for the market; customers are looking to purchase gas at a price lower than the LDC buy/sell price; and there is pressure for the LDCs to separate the merchant functions from the distribution functions in most of the provinces in Canada. The direct and long term impact of these developments will be to enhance competition among distributors.

  16. Exploring the Tuolumne River:An Interactive CD ROM on Fluvial Processes

    Science.gov (United States)

    Reid, J. B.; Murray, D. D.; Sammons, J. I.; Woolf, B.; Kidder, J.

    2001-12-01

    We have created an electronic field investigation to help students discover the dynamics of river processes using the example of the Tuolumne River, in Yosemite National Park. The experience simulates a field trip to Tuolumne Meadows, where the students make a series of visual observations based on ground and aerial photographs. We want them to build as full a set of objective observations as possible before they engage in interpretation. The program records the specific locations in the photographs where the observations have been made, allowing an electronic assessment of the diversity of the students' descriptions. Students also "acquire" real field data (bathymetry, flow and grain size distributions, and the outer bank position through time) in a two stage process: (1) they predict the bathymetry, the flow patterns, etc. based on a careful scrutiny of the photographs and (2) they "do the experiments" to get the real field data. The computer then evaluates the match in each case, and asks a series of tailored socratic questions to lead the students to a richer understanding. When the "observations" are complete, we help them organize a logically sequential Results Section, and then a self-consistent hypothesis. Finally, for further investigation, we provide a set of photographs of other ivers, each of which has a rich "story" of its own. Our goals for this project are: (1) to have students discover for themselves how rivers "work" at their own pace and level of sophistication, and (2) to model the scientific method so that it can applied to other geologic investigations.

  2. Review of A Compendium of Pevsner's Buildings of England [CD=-ROM

    Directory of Open Access Journals (Sweden)

    Malcolm Airs

    1999-11-01

    Full Text Available Misleading titles might seem a good idea to the marketing department of a publishing house but by raising expectations that cannot be fulfilled they run the risk of concealing the real merits of a publication. Thus this very useful CD was launched in 1995 by Oxford University Press at an extraordinarily high price under the guise of providing something very much more comprehensive than it could deliver. Not surprisingly, it failed to sell in sufficient numbers and was dropped from the publisher's list but thankfully it has been rescued by the enterprising compiler and the remaining copies are available directly from him at less than a third of the original price. For the serious student of above-ground archaeology in its widest meaning, it is well worth purchasing at the new price provided that its limitations are recognised at the outset. It is not a compendium in any meaningful sense of that word. At the very least, that would suggest elements of the text and some of the plans and photographs and it contains none of these. Quite simply, it is a text-only index to the Buildings of England and I calculate that if it had been available thirty years ago when I was embarking on my doctoral dissertation it would have saved me something like a year of research time. It is not a substitute for the text of the series, whose strengths and weaknesses are well enough known not to need rehearsing here, but it is the key to unlocking the vast amount of information that is contained in each volume and ordering that information into patterns that are both useful and illuminating.

  3. Mechanisms of supply unbundling from the LDC perspective; CD-ROM ed.

    Energy Technology Data Exchange (ETDEWEB)

    Gang, M.W.

    1996-05-01

    Critical concerns in the unbundling of services by Local Distribution Companies (LDCs) were identified. These issues are addressed from the perspective of the LDC and from the perspective of convincing both the LDC and state regulators that unbundling will produce benefits for both the LDC and its customers, while maintaining reliable service. The five major concerns are: (1) maintaining reliability of service to core customers and cost of maintaining such service, (2) responsibility for maintaining service to indigent customers and obligation for LDCs to be the supplier of last resort, (3) permission for LDCs and/or affiliates to compete in the supply function,or being restricted to distribution and related services, (4) services the LDC should be permitted to provide exclusively, and (5) level of regulation to be applied to alternative suppliers and means of applying this regulation. It was asserted that many of these issues can be resolved expeditiously if LDCs retain the primary role in planning and obtaining capacity to deliver supplies to their city gates.

  5. Proceedings of the CEATI demand side management workshop on understanding customer response. CD-ROM ed.

    International Nuclear Information System (INIS)

    Demand for electricity continues to increase in the midst of environmental concerns, deregulation and the rapid evolution of technology. In order to succeed in a changing environment, utilities must be both adaptive and innovative. Growing concerns over supply and the environmental effects of rising consumption rates have led many utilities to establish demand side management (DSM) programs. However, some utilities have failed to consider the importance of customer behaviour in the success of DSM programs. This conference examined various successful initiatives to encourage customers to reduce their individual or corporate demands for energy. The influence of branding, technology, information prices signals and various other strategies were explored. Issues concerning energy efficiency and customer feedback were discussed. The effect of alternative pricing regimes on DSM programs was investigated. Various information system tools were also examined, and the value of real time electricity monitoring was evaluated. Various DSM initiatives in North America were used to establish benchmarks for the successful implementation of DSM strategies. The conference was divided into 3 sessions: (1) involving the customer in reducing demand; (2) the success of energy efficiency and demand response programs : the impact of branding and the impact of price signals; and (3) the technologies and innovations needed to make it work. The conference featured 13 presentations, of which 8 have been catalogued separately for inclusion in this database. refs., tabs., figs

  15. Welcome to NASA's Earth Science Enterprise: Educational CD-ROM Activity Supplement

    Science.gov (United States)

    1999-01-01

    Since its inception in 1958, NASA has been studying the Earth and its changing environment by observing the atmosphere, oceans, land, ice, and snow, and their influence on weather and climate. We now understand that the key to gaining a better understanding of the global environment is exploring how the Earth's systems of air, land, water, and life interact with each other. This approach-called Earth Systems Science-blends together fields like meteorology, oceanography, geology, and biology. In 1991, NASA launched a more comprehensive program to study the Earth as an integrated environmental system. They call it NASA's Earth Science Enterprise. A major component of the Earth Science Enterprise is the Earth Observing System (EOS). EOS is series of satellites to be launched over the next two decades that will be used to intensively study the Earth, with the hopes of expanding our under- standing of how natural processes affect us, and how we might be affecting them. Such studies will yield improved weather forecasts, tools for managing agriculture and forests, information for fishermen and local planners, and, eventually, the ability to predict how the climate will change in the future. Today's program is laying the foundation for long-term environmental and climate monitoring and prediction. Potentially, this will provide the understanding needed in the future to support difficult decisions regarding the Earth's environment.

  14. Review of Perseus 2.0: Sources and Studies on Ancient Greek Culture [CD-ROM

    Harrison Eiteljorg, II

    1997-01-01

    Full Text Available I have a love-hate relationship with the Perseus Project. Since I first learned about it, when it was still a plan more than a project, I have been impressed by its audacious scope. I have also been very impressed by the far-sightedness of the project directors as they have made certain that the data they store - not necessarily the data they put out on the commercial CDs but the underlying data stored on disc at project headquarters - have been stored in the most sophisticated and neutral formats possible. They have, for instance, used SGML for text and complex databases for other information. They are also storing mapping information in GIS format. On the other hand, I have found myself unimpressed with the CDs produced, both the original one in 1992 and the most recent version, Perseus 2.0, which was released recently. There is much in the new version to admire, much that impresses. Unfortunately, though, there is also much that is worrisome or ineffective or simply not of good quality.

    Driving was introduced as a program transformation technique by Valentin Turchin in some papers around 1980. It was intended for the programming language REFAL and used in metasystem transitions based on super compilation. In this paper we present one version of driving for a more conventional lisp......-like language. Our aim is to extract a simple notion of driving and show that even in this tamed form it has much of the power of more general notions of driving. Our driving technique may be used to simplify functional programs which use function composition and will often be able to remove intermediate data...

  20. The Inorganic Illustrator: A 3-D Graphical Supplement for Inorganic and Bioinorganic Chemistry Courses Distributed on CD-ROM

    Science.gov (United States)

    Childs, Scott L.; Hagen, Karl S.

    1996-10-01

    The visualization of molecular and solid state chemical structures in three dimensions is a particularly difficult problem for students to overcome when the primary means of communication is the two-dimensional world of textbooks, blackboards, and overhead projector screens. Recent editions of popular textbooks in organic, inorganic, and biochemistry have included stereoviews of molecules to aid the student, and stereoviews of crystal structures have been used in inorganic chemistry publications for many years. These are powerful aids for visualizing complex molecules, but with the exception of the biochemistry text mentioned above, they are limited to single, static images generally in black and white. Molecular model kits are routinely used very effectively in organic chemistry but their utility in inorganic chemistry is limited to all but the most simple molecules encountered. Now that personal computers are generally accessible and multimedia tools are starting to make an appearance in chemistry lecture halls (1), we can make our inorganic and bioinorganic chemistry and crystallography lectures come alive with the aid of the computer-based resources, which are the essence of this project. As part of this project we are accumulating a database of representative crystal structures of main group molecules, coordination complexes, organometallic compounds, small metalloproteins, bioinorganic model complexes, clusters, and solid state materials in Chem3D Plus format to be viewed with Chem3D Viewer, which is free software from Cambridge Scientific Computing. We are also generating a library of high-quality graphic images of these same molecules and structures using Cerius2 package from Molecular Simulations. These include polyhedral representations of clusters and solid state structures (see Fig. 1). Figure 1. Representation of the user interface: the title page and an example of polyhedral and ball-and-stick representation of an octanuclear iron-oxo cluster. The files of solid state structures will not be limited to single unit cells that are common in textbooks, but will present multiple cells such that the extended lattice of the material is evident. Navigation through these resources is through a unique open hypertext-based interface using Authorware, which allows the user to create complex applications that support movies, animation, and other graphics seamlessly. Chem3D Viewer is a powerful program that allows not only multiple visualization modes, but also the detailed analysis of both bonded and nonbonded distances and angles. This is particularly useful for recognizing symmetry elements within molecules, as the student can precisely align atoms along the screen's Cartesian axes or within its planes and subsequently rotate the molecules about the axes at precise angles. We are developing stand-alone interactive tutorials to assign point groups to molecules and clusters. In addition, tutorials are being developed that show how the Chem3D Viewer software can be most effectively used in a classroom setting for lectures or for home or lab use by the students. The Inorganic Illustrator will be made available to the education community for the cost of materials plus shipping and handling.

    The Annual Canadian Urban Transit Association Conference attracted speakers from both Canada and the United States. The topics discussed during the 17 sessions fell in the broad categories of smart growth and urban transit, innovation and new ideas in the transit industry, urban transportation and climate change, the future of transit and the environment, as well as active transportation and its impact on human health. It is felt that public transit should represent the primary solution to urban mobility, with the aim of achieving sustainable transportation. Urban transit and the various means by which it can have an impact on the reduction of greenhouse gases emissions and global climate change were discussed in great depth. Community growth has spurred the demand for additional transportation, and presents challenges particular to each community. Discussions also focused on the resulting air quality and pollution problems along with some proposed solutions. Clean fuels, such as compressed natural gas, propane and methanol were also touched upon, as were emerging technologies in the fields of vehicle and new propulsion technologies. The impact of public transit on public health, from the point of view of air quality, climate change and safety was discussed. A total of 35 papers were presented at this conference, of which 9 were processed separately for inclusion in the database. tabs., figs

    Fast wave current drive is demonstrated in the Princeton ACT-I toroidal device. The fast Alfven wave, in the range of high ion-cyclotron harmonics, produced 40 A of current from 1 kW of rf power coupled into the plasma by fast wave loop antenna. This wave excites a steady current by damping on the energetic tail of the electron distribution function in the same way as lower-hybrid current drive, except that fast wave current drive is appropriate for higher plasma densities.

    This paper discusses the predicted increase in the occurrence and severity of motion sickness in self-driving cars. Self-driving cars have the potential to lead to significant benefits. From the driver's perspective, the direct benefits of this technology are considered increased comfort and productivity. However, we here show that the envisaged scenarios all lead to an increased risk of motion sickness. As such, the benefits this technology is assumed to bring may not be capitalised on, in particular by those already susceptible to motion sickness. This can negatively affect user acceptance and uptake and, in turn, limit the potential socioeconomic benefits that this emerging technology may provide. Following a discussion on the causes of motion sickness in the context of self-driving cars, we present guidelines to steer the design and development of automated vehicle technologies. The aim is to limit or avoid the impact of motion sickness and ultimately promote the uptake of self-driving cars. Attention is also given to less well known consequences of motion sickness, in particular negative aftereffects such as postural instability, and detrimental effects on task performance and how this may impact the use and design of self-driving cars. We conclude that basic perceptual mechanisms need to be considered in the design process whereby self-driving cars cannot simply be thought of as living rooms, offices, or entertainment venues on wheels.

    Full Text Available Epilepsy is a disease with high prevalence, which interferes driving and may lead to car accident; This case-control study has been done on 100 epileptic patients and 100 persons as control group, who had history of driving. We gathered our patients with face to face interview and registering their information in special forms which were prepared for this study. There were three times more accidents among epileptic cases comparing with control group and this difference was more considerable in men and in patients under 35 years old. The cause of accident were not seizure attack in more than 60% of the patients and these ordinary accidents were also more in case group. Epileptic patients with history of car accidents during driving had poor drug compliance comparing with the epileptics without history of an accident so drug compliance may be valuable in predicting accident in these patients. We have also found poor drug compliance in whom seizure attacks caused accident for them. 58% of the epileptics had not consulted their physician about driving. 43.3% of seizures during driving were of generalized type and none of the patients had inform police about their disease during getting driving license.

    1992-04-01

    Many European countries test cars, but not their drivers, as they age. There is evidence to suggest that human factors are more important than vehicular factors as causes of motor crashes. The elderly also are involved in more accidents per distance travelled than middle-aged drivers. As the UK relies on self-certification of health by drivers over the age of 70 years, we examined the driving practices of patients with dementia attending a Memory Clinic. Nearly one-fifth of 329 patients with documented dementia continued to drive after the onset of dementia, and impaired driving ability was noted in two-thirds of these. Their families experienced great difficulty in persuading patients to stop driving, and had to invoke outside help in many cases. Neuropsychological tests did not help to identify those who drove badly while activity of daily living scores were related to driving ability. These findings suggest that many patients with dementia drive in an unsafe fashion after the onset of the illness. The present system of self-certification of health by the elderly for driver-licensing purposes needs to be reassessed.

    2014-10-01

    The present study examined the types of situations that cause Malaysian drivers to become angry. The 33-item version of the driver anger scale (Deffenbacher et al., 1994) was used to investigate driver anger amongst a sample of 339 drivers. Confirmatory factor analysis showed that the fit of the original six-factor model (discourtesy, traffic obstructions, hostile gestures, slow driving, illegal driving and police presence), after removing one item and allowing three error pairs to covary, was satisfactory. Female drivers reported more anger, than males, caused by traffic obstruction and hostile gestures. Age was also negatively related to five (discourtesy, traffic obstructions, hostile gestures, slow driving and police presence) of the six factors and also to the total DAS score. Furthermore, although they were not directly related to crash involvement, several of the six forms of driving anger were significantly related to the crash-related conditions of: near misses, loss of concentration, having lost control of a vehicle and being ticketed. Overall the pattern of findings made in the present research were broadly similar to those from Western countries, indicating that the DAS is a valid measure of driving anger even among non-European based cultures.

    Some drugs are known to impair driving because they can change the vision or hearing, and/or disrupt the intellectual or motor abilities: impaired vigilance, sedation, disinhibition effect, the coordination of movement disorders and the balance. The doctor during prescribing and the pharmacist during deliverance of drug treatment should inform their patients of the potential risks of drugs on driving or operating machinery. The driver has direct responsibility, who hired him and him alone, to follow the medical advice received. The pictograms on the outer packaging of medicinal products intended to classify substances according to their risk driving: The driver can whether to observe simple precautions (level one "be prudent"), or follow the advice of a health professional (level two "be very careful"), or if it is totally not drive (level three "danger caution: do not drive"). This classification only evaluates the intrinsic danger of drugs but not the individual variability. Medicines should be taken into account also the conditions for which the medication is prescribed. It is important to inform the patient on several points. PMID:25956300

    Convection in stellar envelopes affects not only the stellar structure, but has a strong impact on different astrophysical processes, such as dynamo-generated magnetic fields, stellar activity and transport of angular momentum. Solar and stellar observations from ground and space have shown that the turbulent convective motion can also drive global oscillations in many type of stars, allowing to study stellar interiors at different evolutionary stages. In this talk I will concentrate on the influence of convection on the driving of stochastic and coherent pulsations across the Hertzsprung-Russell diagram and give an overview of recent studies.

  19. Control rod drive

    International Nuclear Information System (INIS)

    Object: To provide a simple and compact construction of an apparatus for driving a drive shaft inside with a magnetic force from the outside of the primary system water side. Structure: The weight of a plunger provided with an attraction plate is supported by a plunger lift spring means so as to provide a buffer action at the time of momentary movement while also permitting the load on lift coil to be constituted solely by the load on the drive shaft. In addition, by arranging the attraction plate and lift coil so that they face each other with a small gap there-between, it is made possible to reduce the size and permit efficient utilization of the attracting force. Because of the small size, cooling can be simply carried out. Further, since there is no mechanical penetration portion, there is no possibility of leakage of the primary system water. Furthermore, concentration of load on a latch pin is prevented by arranging so that with a structure the load of the control rod to be directly beared through the scrum latch. (Kamimura, M.)

    International Nuclear Information System (INIS)

    The present invention concerns an electromotive driving-type control rod driving system of a BWR type reactor, for which sliding resistance (friction) test can be performed of a movable portion of the control rod driving mechanisms. Namely, a hydraulic pressure control unit has following constitutions in addition to a conventional constitution as a sliding resistance test performing function. (1) A restricting valve is disposed downstream of the scram valve of scram pipelines to control flow rate and pressure of pressurized water flown in the pipelines. (2) A pressure gauge detects a pressure between the scram valve and the restricting valve. (3) A flow meter detects the flow rate of pipelines controlled by the restricting valve. (4) A recording pressure detector detects the pressure at the downstream of the restricting valve. (5) The recording device is attached when the sliding resistant test is performed for tracing the pressure measured by the pressure detection device. Further, the scram valve sends electric signals to a central operation chamber when it is fully closed. The central operation chamber has a function of fully opening the restricting valve by way of the electric signals. (I.S.)

    An electric drive that is designed or adapted to a specific application must take into account all the elements of the chain of constituent elements in its use and deployment. In addition to the motor, the transmission, power electronics, control, sensors, and electrical protection systems must be taken into account. The motor and the transmission can be optimized and designed to obtain the best energy efficiency assessment, in particular for dynamic nodes. An inventory and a characterization of these various components is proposed as part of this book's examination and explanation

    Traction drives are traced from early uses as main transmissions in automobiles at the turn of the century to modern, high-powered traction drives capable of transmitting hundreds of horsepower. Recent advances in technology are described which enable today's traction drive to be a serious candidate for off-highway vehicles and helicopter applications. Improvements in materials, traction fluids, design techniques, power loss and life prediction methods will be highlighted. Performance characteristics of the Nasvytis fixed-ratio drive are given. Promising future drive applications, such as helicopter main transmissions and servo-control positioning mechanisms are also addressed.

    Fuji Electric has completed preparation for the production of various cycloconverter variable-speed AC drive systems used for low-speed large-capacity drives, and is ready to supply the optimum system to meet purposes. Among cycloconverter drive systems of Fuji Electric, circulating current-free cycloconverter fed synchronous motor drive is superior in respect of input power factor and equipment capacity, induction motor drive is superior in respect of maintenance, and circulating current cycloconverter fed motor drive is superior in respect of controllability. This report describes outlines, system components, comparison of performances, control systems and their characteristics, and technology for advanced performance of these various cycloconverter drive systems. Furthermore, was introduced a development of hybrid cycloconverter using a GTO thyristor which can regulate input power factor at 1. 2 refs., 14 figs., 1 tab.

  8. Polar drive on OMEGA

    International Nuclear Information System (INIS)

    High-convergence polar-drive experiments are being conducted on OMEGA [T. R. Boehly et al., Opt. Commun. 133, 495 (1997)] using triple-picket laser pulses. The goal of OMEGA experiments is to validate modeling of oblique laser deposition, heat conduction in the presence of nonradial thermal gradients in the corona, and implosion energetics in the presence of laser-plasma interactions such as crossed-beam energy transfer. Simulated shock velocities near the equator, where the beams are obliquely incident, are within 5% of experimentally inferred values in warm plastic shells, well within the required accuracy for ignition. High, near-one-dimensional areal density is obtained in warm-plastic-shell implosions. Simulated back-lit images of the compressing core are in good agreement with measured images. Outstanding questions that will be addressed in the future relate to the role of cross-beam transfer in polar drive irradiation and increasing the energy coupled into the target by decreasing beam obliquity.

  9. Fast wave current drive

    International Nuclear Information System (INIS)

    Experiments on the fast wave in the range of high ion cyclotron harmonics in the ACT-1 device show that current drive is possible with the fast wave just as it is for the lower hybrid wave, except that it is suitable for higher plasma densities. A 1400 loop antenna launched the high ion cyclotron harmonic fast wave [ω/Ω = O(10)] into a He+ plasma with n/sub e/approx. =4 x 1012 cm-3 and B = 4.5 kG. Probe and magnetic loop diagnostics and FIR laser scattering confirmed the presence of the fast wave, and the Rogowski loop indicated that the circulating plasma current increased by up to 40A with 1 kW of coupled power, which is comparable to lower hybrid current drive in the same device with the same unidirectional fast electron beam used as the target for the RF. A phased antenna array would be used for FWCD in a tokamak without the E-beam

  10. Control rod drives

    International Nuclear Information System (INIS)

    Purpose: To rapidly detect the position to which a control rod has been rapidly inserted into the reactor core upon scram in the control rod drives for use in LMFBR type reactors. Constitution: In control rod drives comprising an acceleration spring disposed to the outside of an extension pipe and an acceleration pipe for conducting the spring force to a control rod for rapidly dropping the rod into the reactor core, a magnet having a repulsive force is disposed to each acceleration pipe and guide pipe as decelerating and buffering means for the acceleration pipe. The position of the control rod is detected by the interaction between the magnet and the coils attached to the inside of the guide pipe or reactor lead switch. According to this invention, 85 % scram signal which has hitherto been difficult to be processed electrically can be obtained with a sufficient intensity and with no delay to thereby improve the entire safety of the reactor system. Then, the inserted position and the insertion time can accurately and rapidly be detected. (Horiuchi, T.)

    To avoid driver overload, assistance systems can be adapted regarding the driver’s current strain. Physiological and performance workload measures require special sensors and are problematic concerning sensitivity and specificity. Within the presented study the driver’s stress level was estimated in real-driving based on an analysis of different driving manoeuvres and environmental factors. The analyses show that different driving manoeuvres result in significantly different subjective strain...

  12. Dimensions of driving anger and their relationships with aberrant driving.

    Zhang, Tingru; Chan, Alan H S; Zhang, Wei

    2015-08-01

    The purpose of this study was to investigate the relationship between driving anger and aberrant driving behaviours. An internet-based questionnaire survey was administered to a sample of Chinese drivers, with driving anger measured by a 14-item short Driving Anger Scale (DAS) and the aberrant driving behaviours measured by a 23-item Driver Behaviour Questionnaire (DBQ). The results of Confirmatory Factor Analysis demonstrated that the three-factor model (hostile gesture, arrival-blocking and safety-blocking) of the DAS fitted the driving anger data well. The Exploratory Factor Analysis on DBQ data differentiated four types of aberrant driving, viz. emotional violation, error, deliberate violation and maintaining progress violation. For the anger-aberration relation, it was found that only "arrival-blocking" anger was a significant positive predictor for all four types of aberrant driving behaviours. The "safety-blocking" anger revealed a negative impact on deliberate violations, a finding different from previously established positive anger-aberration relation. These results suggest that drivers with different patterns of driving anger would show different behavioural tendencies and as a result intervention strategies may be differentially effective for drivers of different profiles.

  13. THE IMPACT OF TEXT DRIVING ON DRIVING SAFETY

    2016-09-01

    Full Text Available In an increasingly mobile era, the wide availability of technology for texting and the prevalence of hands-free form have introduced a new safety concern for drivers. To assess this concern, a questionnaire was first deployed online to gain an understanding of drivers’ text driving experiences as well as their demographic information. The results from 232 people revealed that the majority of drivers are aware of the associated risks with texting while driving. However, more than one-fourth of them still frequently send or read text messages while driving. In addition to the questionnaire, through the use of a virtual-reality driving simulator, this study examined drivers’ driving performance while they were engaged in some forms of text driving under different challenging traffic conditions. Through a blocked factorial experiment, drivers would either read a text message or respond to it with two levels of text complexity while using either hand-held or hands-free texting method. Their driving performance was assessed based on the number of driving violations observed in each scenario. Conclusions regarding the impacts of different forms of texting, text complexity, and response mode on drivers driving performance were drawn.

  14. Control rod drives

    International Nuclear Information System (INIS)

    Purpose: To improve the reliability of a device for driving an LMFBR type reactor control rod by providing a buffer unit having a stationary electromagnetic coil and a movable electromagnetic coil in the device to thereby avord impact stress at scram time and to simplify the structure of the buffer unit. Constitution: A non-contact type buffer unit is constructed with a stationary electromagnetic coil, a cable for the stationary coil, a movable electromagnetic coil, a spring cable for the movable coil, and a backup coil spring or the like. Force produced at scram time is delivered without impact by the attracting or repelling force between the stationary coil and the movable coil of the buffer unit. Accordingly, since the buffer unit is of a non-contact type, there is no mechanical impact and thus no large impact stress, and as it has simple configuration, the reliability is improved and the maintenance can be conducted more easily.

    2013-11-01

    Full Text Available Introduction: How important is the emotional life of persons who manifest psychotic symptoms? Aims: The aim of this paper is to review evidence on a causal role for emotions in psychotic processes. Methods: Selective review of literature on affective symptoms in psychoses, on emotions in the production of psychotic symptoms and on dopaminergic models of psychosis. Results: Affective symptoms are relevant across psychoses. Persons with schizophrenia have high levels of emotional reactivity and the intensification of negative affects not only is associated with but also precedes the intensification of psychotic symptoms, which is evidence that negative emotions drive the course of psychotic symptoms. Negative self‑representations are central in psychotic processes and can be the link between negative emotions and psychosis. Evidence favours the notion that persecutory delusions are consistent with negative affects and self‑representations, while grandiose delusions are consistent with a defensive amplification of positive affects and self‑representations. Shame has been proposed as the core emotional experience of psychosis, one in which the self becomes vulnerable to the external world, which is consistent with persecutory experiences. Assaults on the self, under the form of hostility in the family environment and society, are strong predictors of relapse and development of schizophrenia. Assaults on the self which induce social defeat are also strong stimulants of mesolimbic dopaminergic pathways, whose hyperactivity is associated with acute psychotic episodes and the experience of “aberrant salience”, put forward as a dopaminergic model of psychosis. Conclusions: The “defeat of the self” emerges as a central link that binds the experience of negative emotions to the expression of psychotic symptoms and its psychological and neurobiological correlates. The hypothesis gains support that the emotions related to that defeat control

    Gerbershagen, Alexander; Schulte, Daniel

    The thesis presents phase stability studies for the Compact Linear Collider (CLIC) and focuses in particular on CLIC Drive Beam longitudinal phase stabilisation. This topic constitutes one of the main feasibility challenges for CLIC construction and is an essential component of the current CLIC stabilisation campaign. The studies are divided into two large interrelated sections: the simulation studies for the CLIC Drive Beam stability, and measurements, data analysis and simulations of the CLIC Test Facility (CTF3) Drive Beam phase errors. A dedicated software tool has been developed for a step-by-step analysis of the error propagation through the CLIC Drive Beam. It uses realistic RF potential and beam loading amplitude functions for the Drive and Main Beam accelerating structures, complete models of the recombination scheme and compressor chicane as well as of further CLIC Drive Beam modules. The tool has been tested extensively and its functionality has been verified. The phase error propagation at CLIC h...

    2014-05-01

    Full Text Available Background: Age-related cognitive decline is often associated with unsafe driving behavior. We hypothesized that 10 active training sessions in a driving simulator increase cognitive and on-road driving performance. In addition, driving simulator training should outperform cognitive training.Methods: Ninety-one healthy active drivers (62 – 87 years were randomly assigned to either (1 a driving simulator training group, (2 an attention training group (vigilance and selective attention, or (3 a control group. The main outcome variables were on-road driving and cognitive performance. Seventy-seven participants (85% completed the training and were included in the analyses. Training gains were analyzed using a multiple regression analysis with planned comparisons.Results: The driving simulator training group showed an improvement in on-road driving performance compared to the attention training group. In addition, both training groups increased cognitive performance compared to the control group. Conclusion: Driving simulator training offers the potential to enhance driving skills in older drivers. Compared to the attention training, the simulator training seems to be a more powerful program for increasing older drivers’ safety on the road.

  2. Driving anger in Ukraine: Appraisals, not trait driving anger, predict anger intensity while driving.

    Science.gov (United States)

    Stephens, A N; Hill, T; Sullman, M J M

    2016-03-01

    Trait driving anger is often, but not always, found to predict both the intensity of anger while driving and subsequent crash-related behaviours. However, a number of studies have not found support for a direct relationship between one's tendency to become angry and anger reported while driving, suggesting that other factors may mediate this relationship. The present self-report study investigated whether, in anger provoking driving situations, the appraisals made by drivers influence the relationship between trait and state anger. A sample of 339 drivers from Ukraine completed the 33-item version of the Driver Anger Scale (DAS; Deffenbacher et al., 1994) and eight questions about their most recent experience of driving anger. A structural equation model found that the intensity of anger experienced was predicted by the negative evaluations of the situation, which was in turn predicted by trait driving anger. However, trait driving anger itself did not predict anger intensity; supporting the hypothesis that evaluations of the driving situation mediate the relationship between trait and state anger. Further, the unique structure of the DAS required to fit the data from the Ukrainian sample, may indicate that the anger inducing situations in Ukraine are different to those of a more developed country. Future research is needed to investigate driving anger in Ukraine in a broader sample and also to confirm the role of the appraisal process in the development of driving anger in both developed and undeveloped countries.

  4. Noninductive current drive in tokamaks

    International Nuclear Information System (INIS)

    Various current drive mechanisms may be grouped into four classes: (1) injection of energetic particle beams; (2) launching of rf waves; (3) hybrid schemes, which are combinations of various rf schemes (rf plus beams, rf and/or beam plus ohmic heating, etc.); and (4) other schemes, some of which are specific to reactor plasma conditions requiring the presence of alpha particle or intense synchrotron radiation. Particle injection schemes include current drive by neutral beams and relativistic electron beams. The rf schemes include current drive by the lower hybrid (LH) waves, the electron waves, the waves in the ion cyclotron range of frequencies, etc. Only a few of these approaches, however, have been tested experimentally, with the broadest data base available for LH waves. Included in this report are (1) efficiency criteria for current drive, (2) current drive by neutral beam injection, (3) LH current drive, (4) electron cyclotron current drive, (5) current drive by ion cyclotron waves - minority species heating, and (6) current drive by other schemes (such as hybrids and low frequency waves)

To investigate how general practitioners (GPs recognise and manage patients’ fitness to drive, GPs’ attitudes and beliefs about their role as assessors, and GPs’ experiences in assessing and reporting to driving authorities and identify GPs’ educational needs. Methods. Mixed methods: questionnaire mailed to GPs from three rural and two metropolitan Divisons of General Practice in Victoria, Australia. Results. 217/1028 completed questionnaires were returned: 85% recognised a patients’ fitness to drive, 54% felt confident in their assessment ability, 21% felt the GP should have primary responsibility for declaring patients’ fitness to drive, 79% felt that reporting a patient would negatively impact on the doctor-patient relationship, 74% expressed concern about legal liability, and 74% favoured further education. Discussion. This study provides considerable information including recommendations about GP education, the assessment forms, and legal clarification.

  6. Detonation drive pellet injector

    International Nuclear Information System (INIS)

    Detonation drive pellet injector has been developed and tested. By this method the free piston is not necessary because the pellet accelerated the high pressure shock directly. In the experiment, the Teflon pellet (5 mm dia., 5 mm length) was accelerated by hydrogen, oxygen and dilution gas mixtured detonation. When the gas pressure was only 500 kPa and the mixture rates of hydrogen, oxygen and helium were 3:6:1 or 3:6:0, the Teflon pellet speed was up to 747 m/s. Typical experimental results over 300 kPa of the initial gas pressure range are 78--92% of the one-dimensional calculational values. It showed that the pellet could be accelerated by a relative low pressure gas. When the helium dilution rate is larger than 20%, it was often found the strong detonation of which speed is more than the Chapman-Jouguet speed. Then the pellet speed above 1,100 m/s was obtained

  7. Drive-By Pharming

    Science.gov (United States)

    Stamm, Sid; Ramzan, Zulfikar; Jakobsson, Markus

    This paper describes an attack concept termed Drive-by Pharming where an attacker sets up a web page that, when simply viewed by the victim (on a JavaScript-enabled browser), attempts to change the DNS server settings on the victim's home broadband router. As a result, future DNS queries are resolved by a DNS server of the attacker's choice. The attacker can direct the victim's Internet traffic and point the victim to the attacker's own web sites regardless of what domain the victim thinks he is actually going to, potentially leading to the compromise of the victim's credentials. The same attack methodology can be used to make other changes to the router, like replacing its firmware. Routers could then host malicious web pages or engage in click fraud. Since the attack is mounted through viewing a web page, it does not require the attacker to have any physical proximity to the victim nor does it require the explicit download of traditional malicious software. The attack works under the reasonable assumption that the victim has not changed the default management password on their broadband router.

    2000-10-01

    The traveling n=1, m~= q_edge magnetic distortion observed in the Helicity Injected Torus (HIT-II) during coaxial helicity injection (CHI) is responsible for some current profile relaxation. A model for electromotive current drive, called the electron locking model, can account for the results of current drive experiments in both the HIT-II and the original HIT devices. The most relevant of these results involve the the frequencies and directions of the mode itself, the E× B drift, and the electric current drift. In spherical tokamaks with CHI, electrode and coil polarities can be changed to control the relative directions of these drifts. Results from HIT-II experiments with different polarities are shown. These point out the character n=1, m~= q_edge mode, and suggest its role in CHI current drive. The electron locking model is presented, and is also discussed in the context of mean field electrodynamics. This model might also be applied to other types of current drive, such as rotating magnetic field (RMF) current drive, oscillating field current drive (OFCD), steady inductive helicity injection (SIHI), or Ohmic current drive in a reversed field pinch (RFP). These examples are discussed.

  12. Semiclassical instability of warp drives

    International Nuclear Information System (INIS)

    Warp drives, at least theoretically, provide a way to travel at superluminal speeds. However, even if one succeeded in providing the necessary exotic matter to construct them, it would still be necessary to check whether they would survive to the switching on of quantum effects. In this contribution we will report on the behaviour of the Renormalized Stress-Energy Tensor (RSET) in the spacetimes associated with superluminal warp drives. We find that the RSET will exponentially grow in time close to the front wall of the superluminal bubble, hence strongly supporting the conclusion that the warp-drive geometries are unstable against semiclassical back-reaction.

    2016-07-01

    We develop a new system for studying how innate drives are tuned to reflect current physiological needs and capacities, and how they affect sensory-motor processing. We demonstrate the existence of male mating drive in Drosophila, which is transiently and cumulatively reduced as reproductive capacity is depleted by copulations. Dopaminergic activity in the anterior of the superior medial protocerebrum (SMPa) is also transiently and cumulatively reduced in response to matings and serves as a functional neuronal correlate of mating drive. The dopamine signal is transmitted through the D1-like DopR2 receptor to P1 neurons, which also integrate sensory information relevant to the perception of females, and which project to courtship motor centers that initiate and maintain courtship behavior. Mating drive therefore converges with sensory information from the female at the point of transition to motor output, controlling the propensity of a sensory percept to trigger goal-directed behavior.

Unfortunately, several issues seem to forbid their realization. First, a huge amount of exotic matter is required to build them. Second, the presence of quantum fields propagating in superluminal warp-drive geometries makes them semiclassically unstable. Indeed, a Hawking-like high-temperature flux of particles is generated inside the warp-drive bubble, which causes an exponential growth of the energy density measured at the front wall of the bubble by freely falling observers. Moreover, superluminal warp drives remain unstable even if the Lorentz symmetry is broken by the introduction of regulating higher order terms in the Lagrangian of the quantum field. If the dispersion relation of the quantum field is subluminal, a black-hole laser phenomenon yields an exponential amplification of the emitted flux. If it is superluminal, infrared effects cause a linear growth of this flux.

    Driving a vehicle is an indispensable daily behaviour for many people, yet we know little about how it is supported by the brain. Given that driving in the real world involves the engagement of many cognitive systems that rapidly change to meet varying environmental demands, identifying its neural basis presents substantial problems. By employing a unique combination of functional magnetic resonance imaging (fMRI), an accurate interactive virtual simulation of a bustling central London (UK) a...

  1. PHENOMENON OF CARVED DRIVING WHEELS

    Institute of Scientific and Technical Information of China (English)

    LI Xianghua; ZHANG Jianwu

    2007-01-01

    A newly found phenomenon of carved driving wheels of a rea-wheel-drive tractor used in an airport is discussed. The circum of every driving wheel is damaged at three regions, which distribute regularly and uniformly. Everyday, the tractor tows a trailer which are times heavier than the tractor, and moves on the same road in the airport. The phenomenon is explained by the torsional self-excited vibration system of the powertrain. The simplified torsional vibration system is discribed by a 2-order ordinary differential equation, which has a limit circle. Experiments and numerical simulations show the followings: Because of the heavy trailer, the slip ratio of the tractor's driving wheels is very large. Therefore, there is severe torsional self-excited vibration in the tractor's drivetrain, and the self-excited vibration results in severe and regular fluctuations of the rear wheel's velocity. The severe fluctuations in velocity fastens the damage of the driving wheels. At the same time, the time interval in which an arbitrary point in the circum of the driving wheel contacts with the road twice is two times more than the period of the torsional self-excited vibration, and this times explained the existence of three damaged regions. At last, it points out that the phenomenon can be avoided when the torsional damping is large enough.

  3. Efficient Driving of Piezoelectric Transducers Using a Biaxial Driving Technique.

    Directory of Open Access Journals (Sweden)

    Samuel Pichardo

    Full Text Available Efficient driving of piezoelectric materials is desirable when operating transducers for biomedical applications such as high intensity focused ultrasound (HIFU or ultrasound imaging. More efficient operation reduces the electric power required to produce the desired bioeffect or contrast. Our preliminary work [Cole et al. Journal of Physics: Condensed Matter. 2014;26(13:135901.] suggested that driving transducers by applying orthogonal electric fields can significantly reduce the coercivity that opposes ferroelectric switching. We present here the experimental validation of this biaxial driving technique using piezoelectric ceramics typically used in HIFU. A set of narrow-band transducers was fabricated with two sets of electrodes placed in an orthogonal configuration (following the propagation and the lateral mode. The geometry of the ceramic was chosen to have a resonance frequency similar for the propagation and the lateral mode. The average (± s.d. resonance frequency of the samples was 465.1 (± 1.5 kHz. Experiments were conducted in which each pair of electrodes was driven independently and measurements of effective acoustic power were obtained using the radiation force method. The efficiency (acoustic/electric power of the biaxial driving method was compared to the results obtained when driving the ceramic using electrodes placed only in the pole direction. Our results indicate that the biaxial method increases efficiency from 50% to 125% relative to the using a single electric field.

  4. Exploring Forensic Implications of the Fusion Drive

    Full Text Available This paper explores the forensic implications of Apple's Fusion Drive. The Fusion Drive is an example of auto-tiered storage. It uses a combination of a flash drive and a magnetic drive. Data is moved between the drives automatically to maximize system performance. This is different from traditional caches because data is moved and not simply copied. The research included understanding the drive structure, populating the drive, and then accessing data in a controlled setting to observe data migration strategies. It was observed that all the data is first written to the flash drive with 4 GB of free space always maintained. If data on the magnetic drive is frequently accessed, it is promoted to the flash drive while demoting other information. Data is moved at a block-level and not a file-level. The Fusion Drive didn't alter the timestamps of files with data migration.

    This article explicates the theory of drive and describes the development and validation of two measures. A representative set of drive facets was derived from an extensive corpus of human attributes (Study 1). Operationalised using an International Personality Item Pool version (the Drive:IPIP), a three-factor model was extracted from the facets in two samples and confirmed on a third sample (Study 2). The multi-item IPIP measure showed congruence with a short form, based on single-item ratings of the facets, and both demonstrated cross-informant reliability. Evidence also supported the measures' convergent, discriminant, concurrent, and incremental validity (Study 3). Based on very promising findings, the authors hope to initiate a stream of research in what is argued to be a rather neglected niche of individual differences and non-cognitive assessment.

    Coule's primary objection to the Alcubierre "warpdrive" is that the material producing the warp field needs to be superluminal. This difficulty is solved by placing the drive material inside its own warp field (making the drive system part of the payload), but we then have to deal with Low's related objection, that there is then a restricted rate at which this "naked" warp-field can propagate through the background metric. We argue that the propagation of this sort of gravitational wave is no...

    1992-01-01

    The electromechanical systems employed in different branches of industry are utilized most often as drives of working machines which must be fed with electric energy in a continuous, periodic or even discrete way. Some of these machines operate at constant speed, others require wide and varying energy control. In many designs the synchronous cooperation of several electric drives is required in addition to the desired dynamic properties. For these reasons the control of the cooperation and dynamics of electromechanical systems requires the use of computers.This book adopts an unusual approach

    The internal rotation torque generated during operation of a 4-wheel drive vehicle is reduced using a control device whose clutch is attached to one part of the rear-wheel drive shaft. One torque sensor senses the drive torque associated with the rear wheel drive shaft. A second sensor senses the drive torque associated with the front wheel drive shaft. Revolution count sensors sense the revolutions of each drive shaft. By means of a microcomputer, the engagement of the clutch is changed to insure that the ratio of the torque sensors remains constant.

    The data recorded on several write-once (WO) and read-only-memory (ROM) compact discs has been examined byte by byte to determine the locations of all erroneous bytes along the spiral data tracks. This information has been used to determine error-burst and good-data-gap distributions, which specify the occurrence probability versus the length of an error event (burst) and the intervening segments of good data (gaps). The means for determining whether a given error event is a hard or a soft error event have also been developed. The burst and gap distributions exhibit generally similar characteristics for WO and ROM compact discs that are clean, although clustering of errors on the WO media is evident. PMID:21127593

    The Fort Union Formation and equivalent formations of Paleocene age in the northern Rocky Mountains and Great Plains region contain 14 strippable coals that yielded more than 30 percent of the 1.03 billion short tons produced in the United States in 1996. These thick, low contaminant, compliant coals, which are utilized by electric power plants in 28 States, are being assessed by the US Geological Survey. The minable coals occur in the Powder River Basin in Wyoming and Montana, Hanna, Carbon and Greater Green River Basins in Wyoming, and Williston Basin in North Dakota. Production during the past 25 years of thick, high quality Fort Union and equivalent coal beds and zones in the region increased from 40 to more than 340 million short tons. The Powder River Basin is projected to produce 416 million short tons of coal in 2015. Major production in the Powder River Basin is from the Wyodak-Anderson, Anderson-Dietz, and Rosebud coal deposits. Producing Fort Union coals in the Williston Basin include the Beulah-Zap, Hagel, and Harmon coal deposits. Producing Fort Union coals in the Greater Green River Basin are in five beds of the Deadman coal zone. Coal production in the Hanna Basin is from eight beds in the Ferris and Hanna Formations. Coals in the Powder River Basin and Williston Basin contain much less sulfur and ash than coals produced in other regions in the conterminous US. When sulfur values are compared as pounds of SO{sub 2} per million Btu (as received basis), Powder River Basin and Williston Basin coals have the lowest amounts of any coals in the conterminous US.

    Features and product series of AC drives for industrial plants were outlined. Configurations and features of various types of AC drives were briefly discussed which are put into market to meet various requirements for industrial plants and wide ranges of output voltage and capacity. The following product series were outlined; the power bipolar transistor inverter for 3.5-600 kVA in output capacity, IGBT inverter for AC 400 V in output voltage and 1,000 kVA or less, GTO inverter for AC 600 V and 700-2,000 kVA, and cycloconverter for AC 1,000-3,000 V and 1,000 kW-20 MW. The following subjects were outlined as current technical trends of AC drives for industrial plants; increasing in capacity of voltage-source PWM inverters, downsizing of converters through highly efficient cooling and highly dense mounting, spreading of sensorless vector controls, and development of high-voltage large-capacity PWM inverters. 6 figs., 2 tabs.

    2013-01-01

    Solid State Drives (SSDs) are gaining momentum in enterprise and client applications, replacing Hard Disk Drives (HDDs) by offering higher performance and lower power. In the enterprise, developers of data center server and storage systems have seen CPU performance growing exponentially for the past two decades, while HDD performance has improved linearly for the same period. Additionally, multi-core CPU designs and virtualization have increased randomness of storage I/Os. These trends have shifted performance bottlenecks to enterprise storage systems. Business critical applications such as online transaction processing, financial data processing and database mining are increasingly limited by storage performance. In client applications, small mobile platforms are leaving little room for batteries while demanding long life out of them. Therefore, reducing both idle and active power consumption has become critical. Additionally, client storage systems are in need of significant performance improvement as well ...

    Recently it has been shown that time-optimal quantum computation is attained by using the Cartan decomposition of a unitary matrix. We extend this approach by noting that the unitary group is compact. This allows us to reduce the execution time of a quantum algorithm $U_{\\rm alg}$ further by adding an extra gate $W$ to it. This gate $W$ sends $U_{\\rm alg}$ to another algorithm $WU_{\\rm alg}$ which is executable in a shorter time than $U_{\\rm alg}$. We call this technique warp-drive. Here we show both theoretically and experimentally that the execution time of Grover's algorithm is reduced in two-qubit NMR quantum computer. Warp-drive is potentially a powerful tool in accelerating algorithms and reducing the errors in any realization. of a quantum computer

  8. Warp Drive: A New Approach

    Certain classes of higher dimensional models suggest that the Casimir Effect is a candidate for the cosmological constant. In this paper we demonstrate that a sufficiently advanced civilization could, in principal, manipulate the radius of the extra dimension to locally adjust the value of the cosmological constant. This adjustment could be tuned to generate an expansion/contraction of spacetime around a spacecraft creating an exotic form of field-propulsion. Due to the fact that spacetime expansion itself is not restricted by relativity, a faster-than-light 'warp drive' could be created. Calculations of the energy requirements of such a drive are performed and an 'ultimate' speed limit, based on the Planckian limits on the size of the extra dimensions is found.

  9. The warp drive and antigravity

    2004-01-01

    The warp drive envisioned by Alcubierre that can move a spaceship faster than light can, with modification, levitate it as if it were lighter than light, even allow it to go below a black hole's horizon and return unscathed. Wormhole-like versions of the author's `drainhole' (1973) might provide the drive, in the form of a by-pass of the spaceship composed of a multitude of tiny topological tunnels. The by-pass would divert the gravitational `ether' into a sink covering part of the spaceship's hull, connected by the tunnels to a source covering the remainder of the hull, to produce an ether flow like that of a river that disappears underground only to spring forth at a point downstream. This diversion would effectively shield the spaceship from external gravity.

  2. Absorber rod drive for nuclear reactors

    International Nuclear Information System (INIS)

    The invention concerns an absorber rod drive for Boiling Water Reactors, in which a mechanical drive is combined with a hydraulic drive working separately from it, so that both drives are situated concentric within an overall length. The driving torque of a motor is transmitted to a threaded spindle, which moves a free adjacent hollow piston vertically via a fixed nut. The same means are used for the hydraulic liquid which is used as coolant or moderator and there are nozzles, annular gaps and/or bores between the hydraulic system and the reactor pressure vessel for the purpose of pressure compensation. All the components of the absorber rod drive except the sealing housing and the setting drive are situated in one casing tube taking the differential pressure. (orig./HP)

    The rapid development of extremely energy efficient appliances and equipment is essential to curtail catastrophic climate disruption. This will require the on-going development of products that apply all best-practices and that take advantage of the synergies of hybridization and building integration. Beyond that, it requires the development of new disruptive technologies and concepts. To facilitate these goals, in 2011 the Lawrence Berkeley National Laboratory and the U.S. Department of Energy launched the Max Tech and Beyond Design Competition for Ultra-Low-Energy-Use Appliances and Equipment. Now in its third year, the competition supports faculty-lead student design teams at U.S. universities to develop and test new technology prototypes. This talk describes what the competition and the Max Tech Program are doing to drive such rapid technology progress and to facilitate the entry to the market of successful Max Tech prototypes. The talk also initiates a discussion of physicists' unique role in driving that technology progress faster and farther.

  5. Exposure to Movie Reckless Driving in Early Adolescence Predicts Reckless, but Not Inattentive Driving.

    Directory of Open Access Journals (Sweden)

    Evelien Kostermans

    Full Text Available We examine the association between exposure to depictions of reckless driving in movies and unsafe driving, modeling inattentive and reckless driving as separate outcomes.Data were obtained by telephone from 1,630 US adolescents aged 10 to 14 years at baseline who were drivers at a survey 6 years later. Exposure to movie reckless driving was measured based on movies seen from a randomly selected list of 50 movie titles that had been content coded for reckless driving among characters. Associations were tested with inattentive and reckless driving behaviors in the subsequent survey-controlling for baseline age, sex, socioeconomic status, parental education, school performance, extracurricular activities, daily television and video/computer game exposure, number of movies watched per week, self-regulation and sensation seeking.Exposure to movie reckless driving was common, with approximately 10% of movie characters having driven recklessly. Confirmatory factor analysis revealed a significant distinction between items tapping reckless and inattentive driving at the 6th wave. Age and exposure to movie reckless driving at baseline were directly associated with wave-6 reckless (but not inattentive driving. Additionally, growth in sensation seeking mediated a prospective relation between the total number of movies watched per week at baseline and reckless driving, independent of exposure to movie reckless driving. Males and high sensation seekers reported lower seatbelt usage and more reckless driving, whereas lower self-regulation predicted inattentive driving.In this study, exposure to movie reckless driving during early adolescence predicted adolescents' reckless driving, suggesting a direct modeling effect. Other aspects of movies were also associated with reckless driving, with that association mediated through growth in sensation seeking. Predictors of reckless driving were different from predictors of inattentive driving, with lower self

  6. Circuit for Driving Piezoelectric Transducers

    Randall, David P.; Chapsky, Jacob

    2009-01-01

    The figure schematically depicts an oscillator circuit for driving a piezoelectric transducer to excite vibrations in a mechanical structure. The circuit was designed and built to satisfy application-specific requirements to drive a selected one of 16 such transducers at a regulated amplitude and frequency chosen to optimize the amount of work performed by the transducer and to compensate for both (1) temporal variations of the resonance frequency and damping time of each transducer and (2) initially unknown differences among the resonance frequencies and damping times of different transducers. In other words, the circuit is designed to adjust itself to optimize the performance of whichever transducer is selected at any given time. The basic design concept may be adaptable to other applications that involve the use of piezoelectric transducers in ultrasonic cleaners and other apparatuses in which high-frequency mechanical drives are utilized. This circuit includes three resistor-capacitor networks that, together with the selected piezoelectric transducer, constitute a band-pass filter having a peak response at a frequency of about 2 kHz, which is approximately the resonance frequency of the piezoelectric transducers. Gain for generating oscillations is provided by a power hybrid operational amplifier (U1). A junction field-effect transistor (Q1) in combination with a resistor (R4) is used as a voltage-variable resistor to control the magnitude of the oscillation. The voltage-variable resistor is part of a feedback control loop: Part of the output of the oscillator is rectified and filtered for use as a slow negative feedback to the gate of Q1 to keep the output amplitude constant. The response of this control loop is much slower than 2 kHz and, therefore, does not introduce significant distortion of the oscillator output, which is a fairly clean sine wave. The positive AC feedback needed to sustain oscillations is derived from sampling the current through the

    Driving is a stressful task that requires high levels of attention and vigilance to cope properly with job demands, mainly related to working hours and timetables, weather and traffic conditions, passengers and goods safety, responsibility in case of error and/or accident. Scientific literature shows a higher prevalence of cardiovascular, gastrointestinal, neuropsychic and musculoskeletal disorders, and consequent sick leaves, in professional bus/lorry and train drivers. Several studies have emphasized that stress, fatigue and excessive sleepiness give a significant contribution to occupational road and rail accidents. There are noteworthy, interindividual differences concerning alertness/sleepiness and tolerance to fatigue, related to psychophysiological and behavioural characteristics and health status, in particular: age, ability to overcome drowsiness, morningness/eveningness, diet and intake of psychotropic substances (alcohol, drugs, medicaments), primary and secondary sleep disorders (insomnia, ipersomnias, parasomnias).

    Van Tuinen, M

    1994-04-01

    The medical costs associated with motor vehicle crashes are difficult to measure. Most attempts have used crash data and cost data that are only indirectly related to each other or have followed patients in a few hospitals or trauma centers. These studies produce localized estimates or rough national estimates of limited use to policy makers. The result has been a dependence on more readily available mortality data, such as the Fatal Accident Reporting System, to guide automotive safety efforts. The limitations of mortality data and the increasing sophistication of medical care data bases have resulted in a strong interest in obtaining crash-linked morbidity data. Hence, in 1993, the National Highway Traffic Safety Administration (NHTSA) awarded the Missouri Department of Health and six other applicants grants to link automotive crash records to statewide ambulance trip, outpatient care, hospitalization and mortality records. By identifying an individual across multiple data sets, states would be able to determine directly the relationship of driver behaviors and crash characteristics to hospitalization rates and other medical outcomes. Examination of hospital pay source information would expose the toll of automotive crashes on public tax dollars. Having recently completed the record linkage phase of this project, Missouri Department of Health staff are beginning to analyze the impact of automotive crashes on health care costs in Missouri. In this report, three unsafe driving behaviors, failure to use a safety device (seatbelts and motorcycle helmets), driving under the influence of alcohol, and speeding, are related to the risk of hospitalization or death, hospital costs, and expected pay source.

    Science.gov (United States)

    Konrad, Charles E.; Benson, Ralph A.

    1994-01-01

    A drive train for an electric vehicle includes a traction battery, a power drive circuit, a main contactor for connecting and disconnecting the traction battery and the power drive circuit, a voltage detector across contacts of the main contactor, and a controller for controlling the main contactor to prevent movement of its contacts to the closed position when the voltage across the contacts exceeds a predetermined threshold, to thereby protect the contacts of the contactor. The power drive circuit includes an electric traction motor and a DC-to-AC inverter with a capacitive input filter. The controller also inhibits the power drive circuit from driving the motor and thereby discharging the input capacitor if the contacts are inadvertently opened during motoring. A precharging contactor is controlled to charge the input filter capacitor prior to closing the main contactor to further protect the contacts of the main contactor.

    Transmitting and changing the characteristics of force and stroke is a requirement in nearly all mechanisms. Examples include changing linear to rotary motion, providing a 90 deg change in direction, and amplifying stroke or force. Requirements for size, weight, efficiency and reliability create unique problems in spacecraft mechanisms. Flexible metal band and cam drive systems provide powerful solutions to these problems. Band drives, rack and pinion gears, and bell cranks are compared for effectiveness. Band drive issues are discussed including materials, bend radius, fabrication, attachment and reliability. Numerous mechanisms are shown which illustrate practical applications of band drives.

    Several studies have shown that risky driving is especially prevalent among young drivers and recent research has pointed out that driving in adolescence should be investigated in the more general context of adolescent development. The first aim of this contribution was to analyze involvement in risky driving in a normative sample of 645 Italian adolescents, boys and girls, aged 14-17, through a self-report questionnaire. A second aim was to evaluate the association between risky driving and lifestyle, defined as involvement in other health risk behaviors and leisure activities. The main results showed that many adolescents drove cars and motorcycles without the required driving license and the most frequent offences were speeding and failure to maintain a safe braking distance. Gender and age differences were also investigated. Results concerning the association between risky driving and lifestyle showed that risky driving was not an isolated behavior. Boys who displayed risky driving practices were more likely to adopt a lifestyle characterized by high involvement in antisocial behaviors, tobacco smoking, comfort eating and time spent in non-organized activities with friends. Girls involved in risky driving were more likely to be involved in other risk-taking behaviors, antisocial behaviors and drug use.

    In recent years, websites that stress the message of thinness as the ideal and only choice have surfaced on the internet. The possibility that pro-anorexia websites may reinforce restrictive eating and exercise behaviors is an area of concern. In addition, friends may be influencing one another to view these websites, further contributing to drive for thinness in women and drive for muscularity in men. Three hundred male and female undergraduate psychology students responded to questionnaires assessing: internalization of pro-anorexia website content, internalization of general media content, influence of friends to view pro-anorexia websites, peer influence, drive for muscularity, and drive for thinness. Results showed internalization of pro-anorexia website content was positively correlated with drive for thinness in women, and negatively correlated with drive for muscularity in men. Internalization of pro-anorexia website content was found to be related to both drive for thinness in women and drive for muscularity in men.

    Currently in the United States, the heavy majority of plug-in electric vehicle (PEV) sales have been in highly conducive, selected, metropolitan areas; opposed to more broad distribution across the country. The U.S. Department of Energy’s EV Everywhere Grand Challenge is looking carefully at the barriers and opportunities that exist to enable small and midsize communities to partake in the PEV market and benefit from the economic and environmental advantages of PEVs. In order to gain insight into these challenges and barriers, DOE selected a success story (i.e., Drive Electric Vermont) as the subject of this case study, as the state of Vermont is tied with Detroit, Michigan in having the highest percentage of 2014 (most recent complete data) PEV registrations for cold weather U.S. cities and has seen more than a sixfold increase in charging stations over the last three years. The overall objective of this case study was to use the lessons learned from Drive Electric Vermont to determine what activities are most effective at encouraging acquisitions of PEVs and deployment of charging infrastructure in small to midsize communities, prioritizing and sequencing their implementation, identifying robust means for extrapolation, and applying this understanding to other small to midsize communities across the nation. The Drive Electric Vermont Program was formed in 2012 with a goal of increasing the use of electrified transportation in Vermont through policy development, education and outreach, and infrastructure development. The Drive Electric Vermont Program can be broadly broken into four components: (1) strategic planning/leadership, (2) stakeholder/partnership development, (3) education and outreach, and (4) incentives. The early phases of the program focused heavily on strategic planning, and stakeholder and partnership development, followed by a transition to education and outreach activities, charging infrastructure development, and grant and incentive programs

    Chemical and instrumental tests for driving under the influence of alcohol (DUI) measure the concentration of ethanol in the breath (BrAC), while state DUI laws are described in terms of blood alcohol concentration (BAC). Consequently, accurate and fair conversion from BrAC to BAC is crucial to the judicial process. Theoretical treatment of the water-air-ethanol equilibrium system and the related blood-breath-ethanol system, based on principles from general chemistry and biology, yields an equation relating the ratio of BAC to BrAC to the absolute temperature of the breath, the fraction of water in the blood, and the enthalpy and entropy of vaporization of ethanol from aqueous solution. The model equation predicts an average value for the ratio of 2350+100, not significantly different from reported experimental values. An exponential temperature dependence is predicted and has been confirmed experimentally as well. Biological, chemical, and instrumental variables are described along with their contributions to the overall uncertainty in the value of BrAC/BAC. While the forensic science community uses, and debates, a fixed ratio of 2100, the theoretical model suggests that a value of 1880 should be used to reduce the fraction of false positives to <1%.

    1993-08-01

    The drive linac in Phase I of the Argonne Wakefield Accelerator (AWA) will be used to accelerate short duration (10 ps), high charge (100 nC) electron bunches from 2 MV to 20 MV for use in a variety of wakefield acceleration and measurement studies. The high charge is required since this drive bunch will generate the wakefields of interest in various test sections and their amplitudes are proportional to bunch charge. The short bunch duration is required to drive high-frequency wakefields without intra-bunch cancellation effects. The drive linac design was a balance between having a small wake function to maintain a drive bunch energy spread of {le}10% and obtaining an adequate accelerating gradient of {ge}10 MV/m. This yielded a large aperture, low shunt impedance, high group velocity, L-band, standing-wave linac. Details of the design, fabrication, and testing are presented in the following.

    2014-01-01

    Novice teen drivers have long been known to have an increased risk of crashing, as well as increased tendencies toward unsafe and risky driving behaviors. Teens are unique as drivers for several reasons, many of which have implications specifically in the area of distracted driving. This paper reviews several of these features, including the widespread prevalence of mobile device use by teens, their lack of driving experience, the influence of peer passengers as a source of distraction, the role of parents in influencing teens’ attitudes and behaviors relevant to distracted driving and the impact of laws designed to prevent mobile device use by teen drivers. Recommendations for future research include understanding how engagement in a variety of secondary tasks by teen drivers affects their driving performance or crash risk; understanding the respective roles of parents, peers and technology in influencing teen driver behavior; and evaluating the impact of public policy on mitigating teen crash risk related to driver distraction.

    After periodic signals pass through some nonlinear systems, they are usually transformed into noise-like and wide-band chaotic signals. The discrete spectrums of the original periodic signals are often covered by the chaotic spectrums. Recovering the periodic driving signals from the chaotic signals is important not only in theory but also in practical applications. Based on the modeling theory of nonlinear dynamic system, a "polynomial-simple harmonic drive" non-autonomous equation (P-S equation) to approximate the original system is proposed and the approximation error between P-S equation and the original system is obtained. By changing the drive frequency, we obtain the curve of the approximation error vs. drive frequency. Based on the relation between this curve and the spectrums of the original periodic signals, the spectrum of the original driving signal is extracted and the original signal is recovered.

    Full Text Available Purpose: In accordance with aging of populations in many developed countries, number of drivers who suffer from mild cognitive impairment (MCI drivers is increasing. Since it has been reported that driving skill of the MCI drivers are deteriorated, it is important to train themselves in driving situation to preserve their driving skills. The present study was conducted to develop the simple driving simulator system, and to examine the effect of training in this system.Design/methodology/approach: Nineteen university students (8 males and 11 females participated in this study. After the habituation period (approximately 5min, three trials (approximately 12 min were conducted. Experimental situation imitated the real highway course. During trials, dangerous situation that would be resulted in car accident is randomly appeared and participants were required to avoid the car accidents. To avoid the possible car accidents are considered as correct response.Findings: Mean percent of correct responses for male and female were 75.2% and 56.6% in 1st trial and 95.7% and 72.6% in 3rd trial, respectively. Two-way analysis of variance revealed that the main effect of sex(F (1, 14 = 7.84, p < .05 and trials (F (2, 34 = 10.19, p < .001. These results indicate that numbers of car accidents are dramatically decreased and the driving skills of male are superior to that of female.Practical implications: Although the present study revealed the differences in driving skills between the sexes, their driving history was not considered. Driving history of each participant should be examined in future study.Originality/value: Since the improvement of driving skills is revealed, our experimental design is expected as the tool for the preservation of driving skills in the MCI drivers.

  2. Inbreeding drives maize centromere evolution.

    Schneider, Kevin L; Xie, Zidian; Wolfgruber, Thomas K; Presting, Gernot G

    2016-02-23

    Functional centromeres, the chromosomal sites of spindle attachment during cell division, are marked epigenetically by the centromere-specific histone H3 variant cenH3 and typically contain long stretches of centromere-specific tandem DNA repeats (∼1.8 Mb in maize). In 23 inbreds of domesticated maize chosen to represent the genetic diversity of maize germplasm, partial or nearly complete loss of the tandem DNA repeat CentC precedes 57 independent cenH3 relocation events that result in neocentromere formation. Chromosomal regions with newly acquired cenH3 are colonized by the centromere-specific retrotransposon CR2 at a rate that would result in centromere-sized CR2 clusters in 20,000-95,000 y. Three lines of evidence indicate that CentC loss is linked to inbreeding, including (i) CEN10 of temperate lineages, presumed to have experienced a genetic bottleneck, contain less CentC than their tropical relatives; (ii) strong selection for centromere-linked genes in domesticated maize reduced diversity at seven of the ten maize centromeres to only one or two postdomestication haplotypes; and (iii) the centromere with the largest number of haplotypes in domesticated maize (CEN7) has the highest CentC levels in nearly all domesticated lines. Rare recombinations introduced one (CEN2) or more (CEN5) alternate CEN haplotypes while retaining a single haplotype at domestication loci linked to these centromeres. Taken together, this evidence strongly suggests that inbreeding, favored by postdomestication selection for centromere-linked genes affecting key domestication or agricultural traits, drives replacement of the tandem centromere repeats in maize and other crop plants. Similar forces may act during speciation in natural systems. PMID:26858403

  3. What drives successful verbal communication?

    Directory of Open Access Journals (Sweden)

    Miriam eDe Boer

    2013-10-01

    Full Text Available There is a vast amount of potential mappings between behaviours and intentions in communication: a behaviour can indicate a multitude of different intentions, and the same intention can be communicated with a variety of behaviours. Humans routinely solve these many-to-many referential problems when producing utterances for an Addressee. This ability might rely on social cognitive skills, for instance, the ability to manipulate unobservable summary variables to disambiguate ambiguous behaviour of other agents (mentalizing and the drive to invest resources into changing and understanding the mental state of other agents (communicative motivation. Alternatively, the ambiguities of verbal communicative interactions might be solved by general-purpose cognitive abilities that process cues that are incidentally associated with the communicative interaction. In this study, we assess these possibilities by testing which cognitive traits account for communicative success during a verbal referential task. Cognitive traits were assessed with psychometric scores quantifying motivation, mentalizing abilities, and general-purpose cognitive abilities, taxing abstract visuo-spatial abilities. Communicative abilities of participants were assessed by using an on-line interactive task that required a speaker to verbally convey a concept to an Addressee. The communicative success of the utterances was quantified by measuring how frequently a number of Evaluators would infer the correct concept. Speakers with high motivational and general-purpose cognitive abilities generated utterances that were more easily interpreted. These findings extend to the domain of verbal communication the notion that motivational and cognitive factors influence the human ability to rapidly converge on shared communicative innovations.

    2014-11-01

    An adjustable-speed drive (ASD) includes all devices that vary the speed of a rotating load, including those that vary the motor speed and linkage devices that allow constant motor speed while varying the load speed. The Variable Frequency Drive Evaluation Protocol presented here addresses evaluation issues for variable-frequency drives (VFDs) installed on commercial and industrial motor-driven centrifugal fans and pumps for which torque varies with speed. Constant torque load applications, such as those for positive displacement pumps, are not covered by this protocol. Other ASD devices, such as magnetic drive, eddy current drives, variable belt sheave drives, or direct current motor variable voltage drives, are also not addressed. The VFD is by far the most common type of ASD hardware. With VFD speed control on a centrifugal fan or pump motor, energy use follows the affinity laws, which state that the motor electricity demand is a cubic relationship to speed under ideal conditions. Therefore, if the motor runs at 75% speed, the motor demand will ideally be reduced to 42% of full load power; however, with other losses it is about 49% of full load power.

    "Warp drive" spacetimes are useful as "gedanken-experiments" that force us to confront the foundations of general relativity, and among other things, to precisely formulate the notion of "superluminal" communication. We verify the non-perturbative violation of the classical energy conditions of the Alcubierre and Natario warp drive spacetimes and apply linearized gravity to the weak-field warp drive, testing the energy conditions to first and second order of the non-relativistic warp-bubble velocity. We are primarily interested in a secondary feature of the warp drive that has not previously been remarked upon, if it could be built, the warp drive would be an example of a "reaction-less drive". For both the Alcubierre and Natario warp drives we find that the occurrence of significant energy condition violations is not just a high-speed effect, but that the violations persist even at arbitrarily low speeds. An interesting feature of this construction is that it is now meaningful to place a finite mass spaceshi...

    It will be shown that while horizons do not exist for warp drive spacetimes traveling at subluminal velocities horizons begin to develop when a warp drive spacetime reaches luminal velocities. However it will be shown that the control region of a warp drive ship lie within the portion of the warped region that is still causally connected to the ship even at superluminal velocities, therefore allowing a ship to slow to subluminal velocities. Further it is shown that the warped regions which are causally disconnected from a warp ship have no correlation to the ship velocity.

    The major disruption limits the operation of present tokamaks. Experimental evidences point out that the growth of tearing modes or the magnetic islands is primarily responsible for the occurrence. Taking the non-inductive current drive effects into account, a set of 3D nonlinear equation is derived. It is shown from simulation that the growth of the magnetic island is suppressed effectively by RF current drive. It is consistent with recent experiments on the HL-1 tokamak in which the plasma is stabilized by an RF current drive.

    Driving is often nominated as problematic by individuals with chronic whiplash associated disorders (WAD), yet driving-related performance has not been evaluated objectively. The purpose of this study was to test driving-related performance in persons with chronic WAD against healthy controls of similar age, gender and driving experience to determine if driving-related performance in the WAD group was sufficiently impaired to recommend fitness to drive assessment. Driving-related performance was assessed using an advanced driving simulator during three driving scenarios; freeway, residential and a central business district (CBD). Total driving duration was approximately 15min. Five driving tasks which could cause a collision (critical events) were included in the scenarios. In addition, the effect of divided attention (identify red dots projected onto side or rear view mirrors) was assessed three times in each scenario. Driving performance was measured using the simulator performance index (SPI) which is calculated from 12 measures. z-Scores for all SPI measures were calculated for each WAD subject based on mean values of the control subjects. The z-scores were then averaged for the WAD group. A z-score of ≤-2 indicated a driving failing grade in the simulator. The number of collisions over the five critical events was compared between the WAD and control groups as was reaction time and missed response ratio in identifying the red dots. Seventeen WAD and 26 control subjects commenced the driving assessment. Demographic data were comparable between the groups. All subjects completed the freeway scenario but four withdrew during the residential and eight during the CBD scenario because of motion sickness. All scenarios were completed by 14 WAD and 17 control subjects. Mean z-scores for the SPI over the three scenarios was statistically lower in the WAD group (-0.3±0.3; P0.05). Assessment of driving in an advanced driving simulator for approximately 15min revealed

    2009-01-01

    The hazard avoidance camera on the front of NASA's Mars Exploration Rover Spirit took this image after a drive by Spirit on the 1,806th Martian day, or sol, (January 31, 2009) of Spirit's mission on the surface of Mars. The wheel at the bottom right of the image is Spirit's right-front wheel. Because that wheel no longer turns, Spirit drives backwards dragging that wheel. The drive on Sol 1806 covered about 30 centimeters (1 foot). The rover team had planned a longer drive, but Spirit stopped short, apparently from the right front wheel encountering the partially buried rock visible next to that wheel. The hazard avoidance cameras on the front and back of the rover provide wide-angle views. The hill on the horizon in the right half of this image is Husband Hill. Spirit reached the summit of Husband Hill in 2005.

  18. Electromechanical drive for a reactor control system

    International Nuclear Information System (INIS)

    The invention is related to control systems of nuclear researche swimming pool-type reactors. The presented electromechanical drive for a nuclear reactor control system consists of an electromagnetic grip of control element with magnet power supply cable, drum and flexible element, e.g., wire rope. Two branches of the rope which are separated from the electromagnet to the core and the drum form the closed loop. To decrease the dimensions of the drive, the magnet power supply cable serves as a loop flexible element which goes from the electromagnet to the core. For a particular reactor the drive, made according to the invention is 100 mm shorter and 20 mm narrower as compared with the known one, and that is rather significant in cases when a drive is to be installed directly on a control system channel

  19. How mantle slabs drive plate tectonics.

    Science.gov (United States)

    Conrad, Clinton P; Lithgow-Bertelloni, Carolina

    2002-10-01

    The gravitational pull of subducted slabs is thought to drive the motions of Earth's tectonic plates, but the coupling between slabs and plates is not well established. If a slab is mechanically attached to a subducting plate, it can exert a direct pull on the plate. Alternatively, a detached slab may drive a plate by exciting flow in the mantle that exerts a shear traction on the base of the plate. From the geologic history of subduction, we estimated the relative importance of "pull" versus "suction" for the present-day plates. Observed plate motions are best predicted if slabs in the upper mantle are attached to plates and generate slab pull forces that account for about half of the total driving force on plates. Slabs in the lower mantle are supported by viscous mantle forces and drive plates through slab suction.

    While the number of motor vehicle crashes has declined over the years, crashes resulting from distracted driving are increasing in the United States resulting in significant morbidity and mortality. The national public seems to be aware of the dangers associated with using technology while driving, but continues to engage in this dangerous behaviour, and may be unaware of or underestimate the impact of cell phone use on their own driving performance. Problems associated with distracted driving are not limited to novice or teenage drivers; multifaceted universal prevention efforts aimed at impacting large segments of the population may have the greatest impact. Legislation limiting drivers' cell phone use has had little impact, possibly due to low regulation and enforcement. Behaviour change programmes, improved vehicle safety, and public awareness campaigns have been developed as potential preventive efforts to reduce accidents caused by distracted drivers.

    ''Warp drive'' spacetimes are useful as ''gedanken-experiments'' and as a theoretician's probe of the foundations of general relativity. Applying linearized gravity to the weak-field warp drive, i.e., for non-relativistic warp-bubble velocities, we find that the occurrence of energy condition violations in this class of spacetimes is generic to the form of the geometry under consideration and is not simply a side-effect of the ''superluminal'' properties. Using the linearized construction it ...

    International Nuclear Information System (INIS)

    In this Letter we consider a warp drive spacetime where the spaceship can only travel faster than light. Restricting to the two-dimensional case, we find that if the warp drive is placed in an accelerating universe the warp bubble size increases in a comoving way to the expansion of the universe in which it is immersed. Also shown is the result that the apparent velocity of the ship steadily increases with time as phantom energy is accreted onto it

  10. Semiclassical instability of dynamical warp drives

    International Nuclear Information System (INIS)

    Warp drives are very interesting configurations in general relativity: At least theoretically, they provide a way to travel at superluminal speeds, albeit at the cost of requiring exotic matter to exist as solutions of Einstein's equations. However, even if one succeeded in providing the necessary exotic matter to build them, it would still be necessary to check whether they would survive to the switching on of quantum effects. Semiclassical corrections to warp-drive geometries have been analyzed only for eternal warp-drive bubbles traveling at fixed superluminal speeds. Here, we investigate the more realistic case in which a superluminal warp drive is created out of an initially flat spacetime. First of all we analyze the causal structure of eternal and dynamical warp-drive spacetimes. Then we pass to the analysis of the renormalized stress-energy tensor (RSET) of a quantum field in these geometries. While the behavior of the RSET in these geometries has close similarities to that in the geometries associated with gravitational collapse, it shows dramatic differences too. On one side, an observer located at the center of a superluminal warp-drive bubble would generically experience a thermal flux of Hawking particles. On the other side, such Hawking flux will be generically extremely high if the exotic matter supporting the warp drive has its origin in a quantum field satisfying some form of quantum inequalities. Most of all, we find that the RSET will exponentially grow in time close to, and on, the front wall of the superluminal bubble. Consequently, one is led to conclude that the warp-drive geometries are unstable against semiclassical backreaction.

  13. Power threshold for neutral beam current drive

    International Nuclear Information System (INIS)

    For fully noninductive current drive in tokamaks using neutral beams, there is a power and density threshold condition, setting a minimum value for P3/2/n2. If this condition is not met, stationary state cannot occur, and a tokamak discharge will collapse. This is a consequence of the coupling between current and electron temperature, or between current drive efficiency and energy confinement time. 4 figs

  14. Electromagnetic driving units for complex microrobotic systems

    Michel, Frank; Ehrfeld, Wolfgang; Berg, Udo; Degen, Reinhard; Schmitz, Felix

    1998-10-01

    Electromagnetic actuators play an important role in macroscopic robotic systems. In combination with motion transformers, like reducing gear units, angular gears or spindle-screw drives, electromagnetic motors in large product lines ensure the rotational or linear motion of robot driving units and grippers while electromagnets drive valves or part conveyors. In this paper micro actuators and miniaturized motion transformers are introduced which allow a similar development in microrobotics. An electromagnetic motor and a planetary gear box, both with a diameter of 1.9 mm, are already commercially available from the cooperation partner of IMM, the company Dr. Fritz Faulhaber GmbH in Schonaich, Germany. In addition, a motor with a diameter of 2.4 mm is in development. The motors successfully drive an angular gear and a belt drive. A linear stage with a motion range of 7 mm and an overall size as small as 5 X 3.5 X 24 mm3 has been realized involving the motor, a stationary spur gear with zero backlash and a spindle-screw drive. By the use of these commercially available elements complex microrobots can be built up cost-efficiently and rapidly. Furthermore, a batch process has been developed to produce the coils of micro actuator arrays using lithographic techniques with SU-8 resin. In applying these components, the modular construction of complex microrobotic systems becomes feasible.

    Reducing distracters detrimental to commercial truck driving is a critical component of improving the safety performance of commercial drivers, and makes the highways safer for all drivers. This study used a driving simulator to examine effects of cell phone, texting, and email distractions as well as self-reported driver optimism bias on the driving performance of commercial truck drivers. Results revealed that more visually demanding tasks were related to poorer driving performance. However, the cell phone task resulted in less off-the-road eye glances. Drivers reporting being "very skilled" displayed poorer driving performance than those reporting being "skilled." Onboard communication devices provide a practical, yet visually and manually demanding, solution for connecting drivers and dispatchers. Trucking company policies should minimize interaction between dispatchers and drivers when the truck is in motion. Training facilities should integrate driving simulators into the instruction of commercial drivers, targeting over-confident drivers. PMID:26809775

    Full Text Available Driving is a multifactorial behaviour drawing on multiple cognitive, sensory, and physical systems. Dementia is a progressive and degenerative neurological condition that impacts the cognitive processes necessary for safe driving. While a number of studies have examined driving among individuals with Alzheimer’s disease, less is known about the impact of Dementia with Lewy Bodies (DLB on driving safety. The present study compared simulated driving performance of 15 older drivers with mild DLB with that of 21 neurologically healthy control drivers. DLB drivers showed poorer performance on all indicators of simulated driving including an increased number of collisions in the simulator and poorer composite indicators of overall driving performance. A measure of global cognitive function (i.e., the Mini Mental State Exam was found to be related to the overall driving performance. In addition, measures of attention (i.e., Useful Field of View, UFOV and space processing (Visual Object and Space Perception, VOSP, Test correlated significantly with a rater’s assessment of driving performance.

  4. Fundamental limitations on 'warp drive' spacetimes

    International Nuclear Information System (INIS)

    'Warp drive' spacetimes are useful as 'gedanken-experiments' that force us to confront the foundations of general relativity, and among other things, to precisely formulate the notion of 'superluminal' communication. After carefully formulating the Alcubierre and Natario warp drive spacetimes, and verifying their non-perturbative violation of the classical energy conditions, we consider a more modest question and apply linearized gravity to the weak-field warp drive, testing the energy conditions to first and second orders of the warp-bubble velocity, v. Since we take the warp-bubble velocity to be non-relativistic, v << c, we are not primarily interested in the 'superluminal' features of the warp drive. Instead we focus on a secondary feature of the warp drive that has not previously been remarked upon-the warp drive (if it could be built) would be an example of a 'reaction-less drive'. For both the Alcubierre and Natario warp drives we find that the occurrence of significant energy condition violations is not just a high-speed effect, but that the violations persist even at arbitrarily low speeds. A particularly interesting feature of this construction is that it is now meaningful to think of placing a finite mass spaceship at the centre of the warp bubble, and then see how the energy in the warp field compares with the mass-energy of the spaceship. There is no hope of doing this in Alcubierre's original version of the warp field, since by definition the point at the centre of the warp bubble moves on a geodesic and is 'massless'. That is, in Alcubierre's original formalism and in the Natario formalism the spaceship is always treated as a test particle, while in the linearized theory we can treat the spaceship as a finite mass object. For both the Alcubierre and Natario warp drives we find that even at low speeds the net (negative) energy stored in the warp fields must be a significant fraction of the mass of the spaceship

  5. 'Outsmarting Traffic, Together': Driving as Social Navigation

    Directory of Open Access Journals (Sweden)

    Sam Hind

    2014-04-01

    Full Text Available The automotive world is evolving. Ten years ago Nigel Thrift (2004: 41 made the claim that the experience of driving was slipping into our 'technological unconscious'. Only recently the New York Times suggested that with the rise of automated driving, standalone navigation tools as we know them would cease to exist, instead being 'fully absorbed into the machine' (Fisher, 2013. But in order to bridge the gap between past and future driving worlds, another technological evolution is emerging. This short, critical piece charts the rise of what has been called 'social navigation' in the industry; the development of digital mapping platforms designed to foster automotive sociality. It makes two provisional points. Firstly, that 'ludic' conceptualisations can shed light on the ongoing reconfiguration of drivers, vehicles, roads and technological aids such as touch-screen satellite navigation platforms. And secondly, that as a result of this, there is a coming-into-being of a new kind of driving politics; a 'casual politicking' centred on an engagement with digital interfaces. We explicate both by turning our attention towards Waze; a social navigation application that encourages users to interact with various driving dynamics.   

  6. The drive revisited: Mastery and satisfaction.

    Science.gov (United States)

    Denis, Paul

    2016-06-01

    Starting from the theory of the libido and the notions of the experience of satisfaction and the drive for mastery introduced by Freud, the author revisits the notion of the drive by proposing the following model: the drive takes shape in the combination of two currents of libidinal cathexis, one which takes the paths of the 'apparatus for obtaining mastery' (the sense-organs, motricity, etc.) and strives to appropriate the object, and the other which cathects the erotogenic zones and the experience of satisfaction that is experienced through stimulation in contact with the object. The result of this combination of cathexes constitutes a 'representation', the subsequent evocation of which makes it possible to tolerate for a certain period of time the absence of a satisfying object. On the basis of this conception, the author distinguishes the representations proper, vehicles of satisfaction, from imagos and traumatic images which give rise to excitation that does not link up with the paths taken by the drives. This model makes it possible to conciliate the points of view of the advocates of 'object-seeking' and of those who give precedence to the search for pleasure, and, further, to renew our understanding of object-relations, which can then be approached from the angle of their relations to infantile sexuality. Destructiveness is considered in terms of "mastery madness" and not in terms of the late Freudian hypothesis of the death drive.

  8. Space Drive Physics: Introduction and Next Steps

    Science.gov (United States)

    Millis, M. G.

    Research toward the visionary goal of propellantless ``space drives'' is introduced, covering key physics issues and a listing of roughly 2-dozen approaches. The targeted advantage of a space drive is to circumvent the propellant constraints of rockets and the maneuvering limits of light sails by using the interactions between the spacecraft and its surrounding space for propulsion. At present, the scientific foundations from which to engineer a space drive have not been discovered and, objectively, might be impossible. Although no propulsion breakthroughs appear imminent, the subject has matured to where the relevant questions have been broached and are beginning to be answered. The critical make-break issues include; conservation of momentum, uncertain sources of reaction mass, and the net-external thrusting requirement. Note: space drives are not necessarily faster- than-light devices. Speed limits are a separate, unanswered issue. Relevant unsolved physics includes; the sources and mechanisms of inertial frames, coupling of gravitation and electromagnetism, and the nature of the quantum vacuum. The propulsion approaches span mostly stages 1 through 3 of the scientific method (defining the problem, collecting data, and articulating hypotheses), while some have matured to stage 4 (testing hypotheses). Nonviable approaches include `stiction drives,' `gyroscopic antigravity,' and `lifters.' No attempt is made to gauge the prospects of the remaining approaches. Instead, a list of next-step research questions is derived from the examination of these goals, unknowns, and concepts.

    OBJECTIVE This research examined the extent to which teenagers who engaged in one form of risky driving also engaged in other forms and if risky driving measures were reciprocally associated over time. METHODS The data were from waves 1, 2 and 3 (W1, W2 and W3) of the NEXT Generation study, with longitudinal assessment of a nationally representative sample starting with 10th graders starting in 2009–2010. Three measures of risky driving were assessed in autoregressive and cross-lagged analyses: driving while alcohol/drug impaired, Checkpoints Risky Driving Scale (risky and unsafe driving), and secondary task engagement while driving. RESULTS In adjusted auto-regression models the risk variables, demonstrated high levels of stability, with significant associations observed across the three waves. However, associations between variables were inconsistent. DWI at W2 was associated with risky and unsafe driving at W3 (β = 0.21, p driving at W1 was associated with DWI at W2 (β = 0.20, p driving at W2 is associated with secondary task engagement at W3 (β = 0.19, p driving, with prospective associations between the Risky Driving Scale and the other measures, and reciprocal associations between all three variables at some time points. Secondary task engagement, however, appears largely to be an independent measure of risky driving. The findings suggest the importance of implementing interventions that addresses each of these driving risks. PMID:26514232

  10. A friction regulation hybrid driving method for backward motion restraint of the smooth impact drive mechanism

    Wang, Liang; Chen, Dong; Cheng, Tinghai; He, Pu; Lu, Xiaohui; Zhao, Hongwei

    2016-08-01

    The smooth impact drive mechanism (SIDM) is a type of piezoelectric actuator that has been developed for several decades. As a kind of driving method for the SIDM, the traditional sawtooth (TS) wave is always employed. The kinetic friction force during the rapid contraction stage usually results in the generation of a backward motion. A friction regulation hybrid (FRH) driving method realized by a composite waveform for the backward motion restraint of the SIDM is proposed in this paper. The composite waveform is composed of a sawtooth driving (SD) wave and a sinusoidal friction regulation (SFR) wave which is applied to the rapid deformation stage of the SD wave. A prototype of the SIDM was fabricated and its output performance under the excitation of the FRH driving method and the TS wave driving method was tested. The results indicate that the backward motion can be restrained obviously using the FRH driving method. Compared with the driving effect of the TS wave, the backward rates of the prototype in forward and reverse motions are decreased by 83% and 85%, respectively.

    We study quantum dynamics of the adiabatic search algorithm with the equivalent two-level system. Its adiabatic and non-adiabatic evolution is studied and visualized as trajectories of Bloch vectors on a Bloch sphere. We find the change in the non-adiabatic transition probability from exponential decay for the short running time to inverse-square decay in asymptotic running time. The scaling of the critical running time is expressed in terms of the Lambert W function. We derive the transitionless driving Hamiltonian for the adiabatic search algorithm, which makes a quantum state follow the adiabatic path. We demonstrate that a uniform transitionless driving Hamiltonian, approximate to the exact time-dependent driving Hamiltonian, can alter the non-adiabatic transition probability from the inverse square decay to the inverse fourth power decay with the running time. This may open up a new but simple way of speeding up adiabatic quantum dynamics.

    The initial control of the superconductive cavity has recently been performed by applying the FPGA (Field Programmable Gate Array) technology system in DESY Hamburg. This first experiment turned attention to the general recognition of the cavity features and projected control methods. The electrical model of the cavity is taken as a consideration origin. The calibration of the signal channel is considered as a key preparation for an efficient cavity driving. The cavity parameters identification is confirmed as a proper approach for the required performance: driving on resonance during filling and field stabilization during flattop time with reasonable power consumption. The feed-forward and feedback modes were applied successfully for the CHECHIA cavity driving. Representative results of experiments are presented for different levels of the cavity field gradient.

    There is currently a great deal of interest in the problem of driver distraction. Most research focuses on distractions from inside the vehicle, but drivers can also be distracted by objects outside the vehicle. Major roads are increasingly becoming sites for advertising billboards, and there is little research on the potential effects of this advertising on driving performance. The driving simulator experiment presented here examines the effects of billboards on drivers, including older and inexperienced drivers who may be more vulnerable to distractions. The presence of billboards changed drivers' patterns of visual attention, increased the amount of time needed for drivers to respond to road signs, and increased the number of errors in this driving task.

  17. Variable frequency drives : energy efficiency guide

    NONE

    2009-07-01

    This paper presented a guide on variable frequency drive (VFD) technology that was developed to provide a better understanding of VFDs and to facilitate their selection, application, and operation. The guide refers to drives as electronic VFDs. It does not cover variable speed drives (VSDs) that have mechanical or hydraulic controls. The main application for the guide is for off-the-shelf, low voltage VFDs used in combination with commercially available alternating current (ac), polyphase, induction motors in the factional to 500 horsepower range that are 600 V or less and have insulated gate bipolar transistors (IGBT) with pulse width modulation. The guide does not address engineered products for special and large motor applications.

  18. Linearized warp drive and the energy conditions

    ''Warp drive'' spacetimes are useful as ''gedanken-experiments'' and as a theoretician's probe of the foundations of general relativity. Applying linearized gravity to the weak-field warp drive, i.e., for non-relativistic warp-bubble velocities, we find that the occurrence of energy condition violations in this class of spacetimes is generic to the form of the geometry under consideration and is not simply a side-effect of the ''superluminal'' properties. Using the linearized construction it is now possible to compare the warp field energy with the mass-energy of the spaceship, and applying the ''volume integral quantifier'', extremely stringent conditions on the warp drive spacetime are found.

    2016-06-01

    Full Text Available This paper is devoted to the problem of reducing vehicle energy consumption. The authors consider the optimisation of highway driving cycle a way to use the kinetic energy of a car more effectively at various road conditions. The model of a vehicle driving control at the highway which consists of elementary cycles, such as accelerating, free rolling and deceleration under forces of external resistance, was designed. Braking, as an energy dissipation regime, was not included. The influence of the various longitudinal profiles of the road was taken into consideration and included in the model. Ways to use the results of monitoring road and traffic conditions are presented. The method of non-linear programming is used to design the optimal vehicle control function and phase trajectory. The results are presented by improved typical driving cycles that present energy saving as a subject of choice at a specified schedule.

    2005-01-01

    A modified cellular automaton model for traffic flow on highway is proposed with a novel concept about the variable security gap. The concept is first introduced into the original Nagel-Schreckenberg model, which is called the non-sensitive driving cellular automaton model. And then it is incorporated with a sensitive driving NaSch model,in which the randomization brake is arranged before the deterministic deceleration. A parameter related to the variable security gap is determined through simulation. Comparison of the simulation results indicates that the variable security gap has different influence on the two models. The fundamental diagram obtained by simulation with the modified sensitive driving NaSch model shows that the maximumflow are in good agreement with the observed data, indicating that the presented model is more reasonable and realistic.

  1. Strong path convergence from Loewner driving convergence

    CERN Document Server

    Sheffield, Scott

    2010-01-01

    We show that, under mild assumptions on the limiting curve, a sequence of simple chordal planar curves converges uniformly whenever certain Loewner driving functions converge. We extend this result to random curves. The random version applies in particular to random lattice paths that have chordal SLE as a scaling limit, with kappa less than 8 (non-space-filling). Existing SLE convergence proofs often begin by showing that the Loewner driving functions of these paths (viewed from infinity) converge to Brownian motion. Unfortunately, this is not sufficient, and additional arguments are required to complete the proofs. We show that driving function convergence is sufficient if it can be established for both parametrization directions and a generic target.

    The driving ability of patients under therapy with antidepressives is seen less restrictive than some years ago. The inhibition of psychomotor performance is of special interest. Some empirical studies point at antidepressives increasing the risk for accidents at least in elderly patients. Different groups of antidepressants apparently show different effects. Tricyclic antidepressants were shown to worsen cognitive and psychomotor performance in some patients while serotonin reuptake inhibitors and some other new antidepressants may cause less behavioral toxicity. Methodological problems in assessing driving ability and some recent findings are discussed. PMID:9587241

    2000-07-01

    This article describes the government experimental program PRIMUS (PRogram of Intelligent Mobile Unmanned Systems) and the achieved results of phase C demonstrated in summer 1999 on a military prooving ground. In this program there shall be shown the autonomous driving on an unmanned robot in open terrain. The most possible degree of autonomy shall be reached with today's technology to get a platform for different missions. The goal is to release the soldier from high dangerous tasks, to increase the performance and to come to a reduction of personnel and costs with unmanned systems. In phase C of the program two small tracked vehicles (Digitized Wiesel 2, airtransportable by CH53) are used. One as a robot vehicle the other as a command & control system. The Wiesel 2 is configured as a drive by wire-system and therefore well suited for the adaption of control computers. The autonomous detection and avoidance of obstacles in unknown, not cooperative environment is the main task. For navigation and orientation a sensor package is integrated. To detect obstacles the scene in the driving corridor of the robot is scanned 4 times per second by a 3D- Range image camera (LADAR). The measured 3D-range image is converted into a 2D-obstacle map and used as input for calculation of an obstacle free path. The combination of local navigation (obstacle avoidance) and global navigation leads to a collission free driving in open terrain to a predefined goal point with a velocity of up to 25km/h. A contour tracker with a TV-camera as sensor is also implemented which allows to follow contours (e.g. edge of a meadow) or to drive on paved or unpaved roads with a velocity up to 50km/h. In addition to these autonomous driving modes the operator in the command & control station can drive the robot by remote control. All the functions were successfully demonstrated in the summer 1999 on a military prooving ground. During a mission example the robot vehicle covered a distance of several

    People with epilepsy identify driving and employment among their major concerns. People with controlled seizures may be permitted to drive in every state in the United States, but people with uncontrolled seizures are restricted from licensure. Unemployment and underemployment for people with epilepsy are serious problems that depend on the frequency and type of seizure disorder and associated medical and psychological problems. Most jobs, with reasonable accommodation by employers, are suitable for people with epilepsy. Federal protections through the Americans with Disabilities Act confer civil rights protection by law on people with disabilities such as epilepsy. PMID:27086988

    We will apply the quantum inequality type restrictions to Alcubierre's warp drive metric on a scale in which a local region of spacetime can be considered ``flat''. These are inequalities that restrict the magnitude and extent of the negative energy which is needed to form the warp drive metric. From this we are able to place limits on the parameters of the ``Warp Bubble''. It will be shown that the bubble wall thickness is on the order of only a few hundred Planck lengths. Then we will show ...

    Polar direct drive (PDD), a promising ignition path for the NIF while the beams are in the indirect-drive configuration, is currently being investigated on the OMEGA laser system by using 40 beams in six rings repointed to more uniformly illuminate the target. The OMEGA experiments are being performed with standard, “warm” targets with and without the use of an equatorial “Saturn-like” toroidally shaped CH ring. Target implosion symmetry is diagnosed with framed x-ray backlighting using additional OMEGA beams and by time-integrated x-ray imaging of the stagnating core.

    Induction motors are the most important workhorses in industry. They are mostly used as constant-speed drives when fed from a voltage source of fixed frequency. Advent of advanced power electronic converters and powerful digital signal processors, however, has made possible the development of high performance, adjustable speed AC motor drives.This book aims to explore new areas of induction motor control based on artificial intelligence (AI) techniques in order to make the controller less sensitive to parameter changes. Selected AI techniques are applied for different induction motor control s.

  9. Driving styles among young novice drivers--the contribution of parental driving styles and personal characteristics.

    2010-03-01

    As part of the effort to ascertain why young drivers are more at risk for car crashes, attention has recently turned to the effects of family, including the intergenerational transmission of driving styles from parents to offspring. The current study sought to further understanding of the nature and aspects of the family influence with the help of Bowen's family systems theory. In Phase 1 of the prospective study, 130 young driving students completed questionnaires tapping personal and personality measures, and their parents completed driving-related instruments. In Phase 2, a year after the young drivers had obtained their driver's license, they were administered the same questionnaires their parents had previously completed. The results show significant correlations between the parents' driving styles and those of their offspring a year after licensure. Furthermore, differentiation of self and self-efficacy in newly acquired driving skills were found to moderate or heighten the similarity between the driving styles of parents and their offspring. For young drivers reporting anxiety in Phase 1, this was associated with a reported anxious driving style a year later. Among young female drivers, anxiety was also associated with a reckless and careless style. Higher sensation seeking was related to higher reckless driving among young male drivers. The findings are discussed in the context of adolescence and the role of the study variables in the development and intergenerational transmission of driving styles. In addition to its theoretical contribution to the realms of intergenerational transmission in general, and young drivers in particular, the study may have practical implications for both family therapy and the design of driving interventions.

    In the following contribution, the hybrid drives will be sorted as follows: Hybrid drives by using classical car transmissions, Hybrid drives by using power split transmissions, Hybrid drives without mechanical transmissions. Within this paper only newest drive configurations will be considered. For example, solutions without torque converter in connection to an automatic transmission, CVT or an automated manual transmission are counted among to new drive configurations. Further, solutions to consist of a combination of electric machines and one - or two planetary gear sets are counted among too. Also newest developments of electric transmissions are considered which contain a special electrical drive structure without any mechanical transmission. (orig.)

  13. Forgiveness and consideration of future consequences in aggressive driving.

    2008-09-01

    Most research on aggressive driving has focused on identifying aspects of driver personality which will exacerbate it (e.g., sensation seeking, impulsiveness, driving anger, etc.). The present study was designed to examine two theoretically relevant but previously unexplored personality factors predicted to reduce the risk of aggressive driving: trait forgiveness and consideration of future consequences. The utility of these variables in predicting aggressive driving and driving anger expression was evaluated among 316 college student volunteers. Hierarchical multiple regressions permitted an analysis of the incremental validity of these constructs beyond respondent gender, age, miles driven per week, and driving anger. Both forgiveness and consideration of future consequences contributed to the prediction of aggressive driving and driving anger expression, independent of driving anger. Research on aggressive driving may be enhanced by greater attention to adaptive, potentially risk-reducing traits. Moreover, forgiveness and consideration of future consequences may have implications for accident prevention.

    PHEVs are discussed controversially. On the one hand, the evolutionary approach of a hybrid vehicle helps the consumer to adopt to electric driving, using the range extender when driving longer distances. On the other hand, PHEVs have a more complex propulsion system and a potentially low emission impact due to a low electric driving share. These factors, however, strongly depend on the consumers' driving and charging behavior. Therefore, this paper simulates realistic driving based on the na...

    Grube, J W; Voas, R B

    1996-12-01

    A social-psychological model of underage drinking and driving (DUI) and riding with drinking drivers (RWDD) was tested with data from a random digit dial telephone survey of 706 16-20-year-old drivers from seven western states in the United States. Consistent with the model, a structural equations analysis indicated that DUI and RWDD were primarily predicted by (a) expectancies regarding the physical risks of DUI, (b) normative beliefs about the extent to which friends would disapprove of DUI, (c) control beliefs about the ease or difficulty of avoiding DUI and RWDD and (d) drinking. Expectancies concerning enforcement had a significant effect on RWDD, but not on DUI. Among the background and environmental variables included in the analysis, only night-time driving and age had significant direct effects on DUI and RWDD. Drinking and involvement in risky driving had indirect effects on DUI and RWDD that were mediated through expectancies and normative beliefs. Males, European Americans, Latinos, respondents who drove more frequently and respondents who were less educated held beliefs that were more favorable toward DUI and RWDD, drank more and engaged more frequently in risky driving. As a result, such individuals may be at greater risk for DUI and RWDD. PMID:8997765
