    Full Text Available Le numérique, simple mue du libéralisme, ou avènement d’une économie soutenable ? La société de l’information, puisant l’essentiel de son potentiel dans la simplification radicale des codes d’écriture et de transmission des données, superpose progressivement à son rôle de moteur de la croissance celui de facteur de développement durable. Cette tendance donne à l’économie de l’immatériel un caractère désormais prédominant sur la matière et l’énergie dans les processus de création de valeur. Nous formulons l’hypothèse, appuyée sur des sources bibliographiques et sur l’observation de l’essor actuel des technologies numériques et de leurs usages, que cette dynamique de mutation est soutenue par la nature même de l’information : son caractère reproductible permet à l’économie de l’information de s’affranchir des lois de la rareté, et d’optimiser l’ensemble des activités de production. Des rapports juridiques innovants et des "jeux à somme non nulle" apparaissent, substituant aux comportements de domination inhérents à un espace fini des attitudes de coopération propices à un développement économe en ressources finies. Ce concours apporté à l’économie par la société de l’information est favorable à la "soutenabilité" de son développement. Contrairement à la matière et à l’énergie, l’information est un facteur de développement non assujetti aux lois de la thermodynamique : peu consommateur de matière, peu dissipateur d’énergie, son impact sur le développement durable est décisif. De plus, le numérique offre des puissances de traitement des données permettant l’agrégation de nombreuses attentes individuelles en choix collectifs complexes, nécessaires à l’exercice d’une responsabilité citoyenne nouvelle, compatible avec la mise en œuvre, au quotidien, des finalités du développement durable.

  2. Reliability assessment - for production and distribution of heat; Riskbaserad tillfoerlitlighet - i produktion och leverans av vaerme

    The content of this project gives the basic framework of a guideline in how to study the reliability of both production and distribution of heat, i.e. the report forms the developing phase of a methodology for identification of potential risks in a system for district heat. The risks are prioritized and used as a decision tool to design a program for mitigation of the risk exposure. This report also describes a basic idea of how to further develop this methodology. The methodology is based on an initial screening with an optional phase of detailed analysis for weak links identified in the initial screening process. The methodology is different to previous tools as it facilitate an efficient approach to identify weak links in all parts of the system for district heat. The objective is to clearly describe the methodology in order to enable performance, also without support from experts in risk engineering. The practicing personnel intend to be technical staff from both the operational- and maintenance departments of a district heat company in general. During the project, several technical meetings were performed and interviews also took place, with engineers intended to be the typical end users of this tool. As a basic part of the methodology, established methodologies of risk assessment were studied. The studies have been a part of the design to achieve a method well adjusted for the end user group. Some parts of the methodology have already been tested in real cases, as several regular analyses have been performed in parallel with the development of this methodology.

  3. How to reliably deliver narrow individual-patient error bars for optimization of pacemaker AV or VV delay using a "pick-the-highest" strategy with haemodynamic measurements.

    Francis, Darrel P

    2013-03-10

    Intuitive and easily-described, "pick-the-highest" is often recommended for quantitative optimization of AV and especially VV delay settings of biventricular pacemakers (BVP; cardiac resynchronization therapy, CRT). But reliable selection of the optimum setting is challenged by beat-to-beat physiological variation, which "pick-the-highest" combats by averaging multiple heartbeats. Optimization is not optimization unless the optimum is identified confidently. This document shows how to calculate how many heartbeats must be averaged to optimize reliably by pick-the-highest. Any reader, by conducting a few measurements, can calculate for locally-available methods (i) biological scatter between replicate measurements, and (ii) curvature of the biological response. With these, for any clinically-desired precision of optimization, the necessary number of heartbeats can be calculated. To achieve 95% confidence of getting within ±∆x of the true optimum, the number of heartbeats needed is 2(scatter/curvature)(2)/∆x(4) per setting. Applying published scatter/curvature values (which readers should re-evaluate locally) indicates that optimizing AV, even coarsely with a 40ms-wide band of precision, requires many thousand beats. For VV delay, the number approaches a million. Moreover, identifying the optimum twice as precisely requires 30-fold more beats. "Pick the highest" is quick to say but slow to do. We must not expect staff to do the impossible; nor criticise them for not doing so. Nor should we assume recommendations and published protocols are well-designed. Reliable AV or VV optimization, using "pick-the-highest" on commonly-recommended manual measurements, is unrealistic. Improving time-efficiency of the optimization process to become clinically realistic may need a curve-fitting strategy instead, with all acquired data marshalled conjointly.

  4. Reliability Of A Novel Intracardiac Electrogram Method For AV And VV Delay Optimization And Comparability To Echocardiography Procedure For Determining Optimal Conduction Delays In CRT Patients

    Directory of Open Access Journals (Sweden)

    2009-03-01

    Full Text Available Background: Echocardiography is widely used to optimize CRT programming. A novel intracardiac electrogram method (IEGM was recently developed as an automated programmer-based method, designed to calculate optimal atrioventricular (AV and interventricular (VV delays and provide optimized delay values as an alternative to standard echocardiographic assessment.Objective: This study was aimed at determining the reliability of this new method. Furthermore the comparability of IEGM to existing echocardiographic parameters for determining optimal conduction delays was verified.Methods: Eleven patients (age 62.9± 8.7; 81% male; 73% ischemic, previously implanted with a cardiac resynchronisation therapy defibrillator (CRT-D underwent both echocardiographic and IEGM-based delay optimization.Results: Applying the IEGM method, concordance of three consecutively performed measurements was found in 3 (27% patients for AV delay and in 5 (45% patients for VV delay. Intra-individual variation between three measurements as assessed by the IEGM technique was up to 20 ms (AV: n=6; VV: n=4. E-wave, diastolic filling time and septal-to-lateral wall motion delay emerged as significantly different between the echo and IEGM optimization techniques (p < 0.05. The final AV delay setting was significantly different between both methods (echo: 126.4 ± 29.4 ms, IEGM: 183.6 ± 16.3 ms; p < 0.001; correlation: R = 0.573, p = 0.066. VV delay showed significant differences for optimized delays (echo: 46.4 ± 23.8 ms, IEGM: 10.9 ± 7.0 ms; p <0.01; correlation: R = -0.278, p = 0.407.Conclusion: The automated programmer-based IEGM-based method provides a simple and safe method to perform CRT optimization. However, the reliability of this method appears to be limited. Thus, it remains difficult for the examiner to determine the optimal hemodynamic settings. Additionally, as there was no correlation between the optimal AV- and VV-delays calculated by the IEGM method and the echo

    Full Text Available Abstract Background In Sweden, as well as in Scandinavia, there is no easy way to evaluate patients' difficulties when they suffer from lateral epicondylitis/epicondylalgia. However, there is a Canadian questionnaire, in English, that could make the evaluation of a patient's pain and functional loss both quick and inexpensive. Therefore, the aim of this study was to translate and cross-culturally adapt the questionnaire "Patient-rated Tennis Elbow Evaluation" into Swedish (PRTEE-S; "Patientskattad Utvärdering av Tennisarmbåge", and to evaluate the reliability and validity of the test. Methods The Patient-rated Tennis Elbow Evaluation was cross-culturally adapted for the Swedish language according to well-established guidelines. Fifty-four patients with unilateral epicondylitis/epicondylalgia were assessed using the PRTEE-S (Patientskattad Utvärdering av Tennisarmbåge, the Disabilities of Arm, Shoulder, and Hand questionnaire, and the Roles & Maudsley score to establish the validity and reliability of the PRTEE-S. Reliability was determined via calculation of the intra-class correlation coefficient (ICC the internal consistency was assessed by Cronbach's alpha, and validity was calculated using Spearman's correlation coefficient. Results The test-retest reliability, using the PRTEE-S (Patientskattad Utvärdering av Tennisarmbåge intraclass correlation coefficient, was 0.95 and the internal consistency was 0.94. The PRTEE-S correlated well with the Disabilities of the Arm, Shoulder, and Hand questionnaire (r = 0.88 and the Roles & Maudsley score (r = 0.78. Conclusion The PRTEE-S (Patientskattad Utvärdering av Tennisarmbåge represents a reliable and valid instrument to evaluate the subjective outcome in Swedish speaking patients with lateral epicondylitis/epicondylalgia, and can be used in both research and clinical settings.

    2017-01-01

    Separating the signal in a test from the irrelevant noise is a challenge for all measurement. Low test reliability limits test validity, attenuates important relationships, and can lead to regression artifacts. Multiple approaches to the assessment and improvement of reliability are discussed. The advantages and disadvantages of several different approaches to reliability are considered. Practical advice on how to assess reliability using open source software is provided.

    Probabilistic Safety Analysis (PSA) is performed for Swedish nuclear power plants in order to make predictions and improvements of system safety. The analysis of the Three Mile Island and Chernobyl accidents contributed to broaden the approach to nuclear power plant safety. A system perspective focusing on the interaction between aspects of Man, Technology and Organization (MTO) emerged in addition to the development of Human Factors knowledge. To take the human influence on the technical system into consideration when performing PSAs, a Human Reliability Analysis (HRA) is performed. PSA is performed for different stages and plant operating states, and the current state of Swedish analyses is Low power and Shutdown (LPSD), also called Shutdown PSA (SPSA). The purpose of this master's thesis is to describe methods and basic models used when analysing human reliability for the LPSD state. The following questions are at issue: 1. How can the LPSD state be characterised and defined? 2. What is important to take into consideration when performing a LPSD HRA? 3. How can human behaviour be modelled for a LPSD risk analysis? 4. According to available empirical material, how are the questions above treated in performed analysis of human operation during LPSD? 5. How does the result of the questions above affect the way methods for analysis of LPSD could and/or should be developed? The procedure of this project has mainly consisted of literature studies of available theory for modelling of human behaviour and risk analysis of the LPSD state. This study regards analysis of planned outages when maintenance, fuel change, tests and inspections are performed. The outage period is characterised by planned maintenance activities performed in rotating 3-shifts, around the clock, as well as many of the persons performing work tasks on the plant being external contractors. The working conditions are characterised by stress due to heat, radiation and physically demanding or

  18. Ultralydfremstilling av fostervekst

    2009-09-01

    Full Text Available Ultralyd billeddanning er i dag den beste undersøkelsesmetoden vi har til å overvåke fosterets utvikling og vekst. Ultralydmåling av fosterets størrelse og biometriske referansetabeller for svangerskapet brukes til å fastsette svangerskapets alder, beregne termin og vurdere fosterets vekst. Optimal studiedesign er ulik for hvert av disse formålene. Det er stor variasjon i fysiologisk vekst og en utfordring å identifisere fostre som har dårlig tilvekst. En enkeltmåling av fosteret kan fortelle oss om det er lite eller stort i forhold til andre fostre, men ikke om størrelsen er passelig i forhold til forventet fysiologisk vekst for dette fosteret. Tilpassede referansemodeller ("customised" justerer forventet størrelse i relasjon til føtale og maternelle faktorer og har vist seg å bedre identifisere sanne veksthemmede fostre enn bare å klassifisere i henhold til 2,5, 5 eller 10 persentilen. Men et foster som i utgangspunktet er stort for alderen, men etter hvert vokser langsomt vil ikke nødvendigvis bli fanget opp ved en slik enkeltmåling. Serielle målinger vil hjelpe, men en slik longitudinell metode blir ikke fullt ut utnyttet før det appliseres betinget ("conditional" vekstberegning. Betingelsesleddene for variasjon i vekst og målemetode kalkuleres ut fra longitudinelle data og kan så anvendes for det enkelte foster. En første måling brukes til å beregne forventet vekst og variasjon for en neste måling. Denne metoden forventes å skjerpe diagnostikken for vekst-avvik i alle vektklasser og kan sammen med tilpasningen av andre faktorer bedre overvåkningen av risikosvangerskapUltrasonographic imaging is today the best method for assessing fetal size and monitoring fetal growth.

Svevestøvet kan deles inn i størrelsesfraksjoner som PMAmbient particulate matter (PM comprises particles from different combustion processes and a variety of mineral particles. The particles vary widely in size distribution and chemical/physical characteristics. PM is often divided into size fractions with different aerodynamic diameters: PM10 (PM ! 10 mm, PM2.5 (PM ! 2.5 mm and PM0.1 (PM ! 0.1 mm. Recent population studies have found an association between an increase in mortality and morbidity due to lung and/or cardiovascular disease and short-term increases in PM. The relative risk (RR was approximately 1.005 for an increase in 10 mg/m3 PM10, without an observed threshold even at concentrations below 10 mg/m3. Chronic exposure has been investigated to a lesser extent, but longterm exposure to PM2.5 has been found to be associated with an approximately 10-fold greater increase in RR than short-term exposures. Experimental studies with volunteers in chamber and field studies show mild lung or cardiovascular responses at concentrations of ambient particles (PM2.5/PM10: 100-200 mg/m3 that may occur during episodes of air pollution. Animal studies at higher concentrations have shown stronger responses. The experimental studies support the epidemiological evidence for an adverse health effect of PM. Both population- and experimental studies indicate the existence of vulnerable individuals. At low to average ambient concentrations there seems to exist a discrepancy between the results of population- and experimental studies that might be due to the absence of the most vulnerable individuals in the experimental studies. Together with cell culture experiments, human and animal studies indicate the importance of physical and chemical properties of the particles (size, content of metals, organics, endotoxins, etc. for

    2011-12-01

    The Arctic Visiting Speakers (AVS) Series funds researchers and other arctic experts to travel and share their knowledge in communities where they might not otherwise connect. Speakers cover a wide range of arctic research topics and can address a variety of audiences including K-12 students, graduate and undergraduate students, and the general public. Host applications are accepted on an on-going basis, depending on funding availability. Applications need to be submitted at least 1 month prior to the expected tour dates. Interested hosts can choose speakers from an online Speakers Bureau or invite a speaker of their choice. Preference is given to individuals and organizations to host speakers that reach a broad audience and the general public. AVS tours are encouraged to span several days, allowing ample time for interactions with faculty, students, local media, and community members. Applications for both domestic and international visits will be considered. Applications for international visits should involve participation of more than one host organization and must include either a US-based speaker or a US-based organization. This is a small but important program that educates the public about Arctic issues. There have been 27 tours since 2007 that have impacted communities across the globe including: Gatineau, Quebec Canada; St. Petersburg, Russia; Piscataway, New Jersey; Cordova, Alaska; Nuuk, Greenland; Elizabethtown, Pennsylvania; Oslo, Norway; Inari, Finland; Borgarnes, Iceland; San Francisco, California and Wolcott, Vermont to name a few. Tours have included lectures to K-12 schools, college and university students, tribal organizations, Boy Scout troops, science center and museum patrons, and the general public. There are approximately 300 attendees enjoying each AVS tour, roughly 4100 people have been reached since 2007. The expectations for each tour are extremely manageable. Hosts must submit a schedule of events and a tour summary to be posted online

Il prévoit d’analyser les parcours éducatifs des adolescents âgés de 13 à 15 ans en croisant à la fois leurs parcours scolaires, leurs activités de loisirs réalisées durant le temps libre et leurs pratiques numériques. Les résultats montrent que la variable territoriale n’apparaît pas comme discriminante s’agissant des équipements numériques mais qu’elle l’est, au même titre que la variable sociale, dès qu’on s’intéresse aux usages des adolescents et à l’encadrement des pratiques à domicile. Dans un souci de justice sociale et spatiale, l’article montre de quelle manière certains collèges s’efforcent de compenser les inégalités liées aux territoires et aux situations sociales.

    Full Text Available  SAMMENDRAGSvalbard er spesielt godt egnet til å vurdere påliteligheten av selvrapportert alkoholkonsum. På grunn av detlave prisnivået for alkohol er ulovlig import eller hjemmeproduksjon av alkohol ukjent på Svalbard. Dessutener samfunnet lite og oversiktlig, slik at det er praktisk mulig å undersøke hele befolkningen. I den aktuellestudien registrerte vi alt salg av alkohol til fastboende nordmenn på Svalbard i oktober og november 1988. Isamme tidsperiode ble alle nordmenn 18 år eller eldre invitert til å ta del i en helseundersøkelse der det inngikkspørsmål om alkoholbruk. Vi fant at selvrapportert alkoholkonsum utgjorde rundt 40% av salgsvolumet.På grunn av de spesielle forhold når det gjelder alkoholomsetning på Svalbard er det grunn til å anta atestimatet i denne studien er mer pålitelig sammenlignet med tilsvarende studier fra andre områder.Høyer G, Nilssen O, Brenn T, Schirmer H. The reliability of self-reported alcohol consumption.The Svalbard study 1988-89. Nor J Epidemiol 1996; 6 (1: 109-113.ENGLISH SUMMARYThe Norwegian island of Spitzbergen, Svalbard offers a unique setting for validation studies on self-reportedalcohol consumption. No counterfeit production or illegal import exists, thus making a complete registrationof all sources of alcohol possible. In this study we recorded sales from all agencies selling alcohol onSvalbard over a two month period in 1988. During the same period all adults living permanently on Svalbardwere invited to take part in a health screening. As part of the screening a self-administered questionnaire onalcohol consumption was introduced to the participants. We found that the self-reported volume accounted forapproximately 40 percent of the sales volume. Because of the unique situation applying to Svalbard, theestimate made in this study is believed to be more reliable compared to other studies using sales volume tovalidate self-reports.

  7. Efficient Software HEVC to AVS2 Transcoding

    Full Text Available The second generation of Audio and Video coding Standard (AVS is developed by the IEEE 1857 Working Group under project 1857.4 and was standardized in 2016 by the AVS Working Group of China as the new broadcasting standard AVS2. High Efficient Video Coding (HEVC is the newest global video coding standard announced in 2013. More and more codings are migrating from H.264/AVC to HEVC because of its higher compression performance. In this paper, we propose an efficient HEVC to AVS2 transcoding algorithm, which applies a multi-stage decoding information utilization framework to maximize the usage of the decoding information in the transcoding process. The proposed algorithm achieves 11×–17× speed gains over the AVS2 reference software RD 14.0 with a modest BD-rate loss of 9.6%–16.6%.

    Full Text Available Arvelig hemokromatose fører til jernopphopning i kroppen, men gir sjelden alvorlig helseskade. Nesten alle hemokromatosepasienter i vårt land er homozygote for C282Y-mutasjonen i HFE-genet. Omtrent 7 per 1000 innbyggere har denne genotypen. Alvorlig syke blir bare omkring 5-15% av homozygote menn og nesten ingen kvinner. Likevel er det holdepunkter for at screening for hemokromatose blant friske, yngre menn kan være kostnadseffektivt. Det er relativt lett å påvise om en person er disponert for sykdommen, i god tid før den bryter ut, og forebyggende behandling er billig og effektiv. Imidlertid kan vi ikke forutsi hvilke screeningpositive personer som ubehandlet får alvorlig sykdom. Et kontrollert forsøk med screening bør gjennomføresHereditary hemochromatosis – benefits of screening. Hereditary hemochromatosis leads to iron accumulation in the body; however, serious illness due to hemochromatosis is rare. In Norway, almost all patients with hemochromatosis are homozygous for the C282Ymutation in the HFE-gene, a genotype carried by about 7 per 1000 inhabitants. Serious complications are seen in only about 5-15% of homozygous men and in very few women. Nevertheless, screening young men for hemochromatosis may be cost-effective. Detecting predisposed men is relatively straightforward, and prophylactic treatment is cheap and effective. However, we can not predict, among screen-positive men, the few who untreated will become seriously ill. A controlled screening trial should be conducted.

Neste modelo a interação entre distribuição de renda e acumulação de capital gera um ciclo de crescimento que oscila em torno de uma trajetória de crescimento equilibrado. O objetivo do presente trabalho é investigar a possibilidade de existência de ciclos goodwinianos com heterogeneidade de salários e de taxas de lucro. Essa análise é realizada considerando o processo de concorrência entre trabalhadores num ambiente de racionalidade limitada. Para formalizar o processo de concorrência entre trabalhadores foram utilizados dois recursos: (i a “alegoria das ilhas”, que tem sido amplamente adotada na macroeconomia moderna, a fim de apreender situações de informação imperfeita; e (ii os instrumentos analíticos desenvolvidos pela teoria dos jogos evolucionários aplicada a ambientes sociais. O modelo construído combina o modelo de Goodwin com uma formalização estilizada do fluxo de trabalho como um processo de imitação num ambiente de racionalidade limitada (dinâmica de replicação num contexto social. Neste modelo demonstra-se a possibilidade de o sistema econômico não convergir para um estado de equilíbrio de longo prazo e a possibilidade do sistema econômico convergir para um ciclo goodwiniano caracterizado por heterogeneidade de salários e de taxas de lucro.This paper starts from the macrodynamical model developed by Richard M.

  11. Fractional order absolute vibration suppression (AVS) controllers

    Science.gov (United States)

    Halevi, Yoram

    2017-04-01

    Absolute vibration suppression (AVS) is a control method for flexible structures. The first step is an accurate, infinite dimension, transfer function (TF), from actuation to measurement. This leads to the collocated, rate feedback AVS controller that in some cases completely eliminates the vibration. In case of the 1D wave equation, the TF consists of pure time delays and low order rational terms, and the AVS controller is rational. In all other cases, the TF and consequently the controller are fractional order in both the delays and the "rational parts". The paper considers stability, performance and actual implementation in such cases.

    PurposeThe study was designed to assess outcomes of arteriovenous (AV) accesses after interventional stent-graft deployment in haemodialysis patients.Materials and Methods63 haemodialysis patients with 66 AV fistulas and AV grafts were treated by interventional stent-graft deployment from 2006 to 2012 at our hospital. Data of these patients were retrospectively analysed for location of deployed stent-grafts, occurrence and location of (re-)stenosis and (re-)thrombosis. Complex stenosis was the most frequent indication for stent-graft deployment (45.5 %), followed by complications of angioplasty with vessel rupture or dissection (31.8 %).ResultsA high rate of procedural success was achieved (98.5 %). The most frequent location of the deployed stent-graft was the draining vein (66.7 %). Stent-graft deployment was more frequent in AV grafts than in AV fistulas. Primary patency was 45.5 % at 6 month, 31.3 % at 12 month and 19.2 % at 24 month. Primary patency was significantly better for AV fistulas than for AV grafts with deployed stent-grafts. Patency of the deployed stent-graft was much better than overall AV access primary patency with deployed stent-graft. Re-stenosis with thrombosis was the most frequent indication for re-intervention. Most frequent location of re-stenosis was the draining vein (37.1 %), followed by stenosis at the AV access (29.5 %) and the deployed stent-graft (23.5 %).ConclusionRe-stenosis and re-thrombosis remain frequent in AV fistulas and AV grafts in haemodialysis patients despite stent-graft deployment. Re-stenosis of the deployed stent-graft is, only in the minority of the cases, responsible for AV access dysfunction.

  7. UNIPASS for AvSP? A Broader View

    Science.gov (United States)

    Wu, N. Eva

    2001-01-01

    UNIPASS is a general-purpose probabilistic computer program consisting of three major modules, including preprocessor, solver and postprocessor. UNIPASS contains a user-friendly Graphical User Interface (GUI), numerous state-of-the-art probabilistic analysis techniques, a large library of statistical distributions and a function module with a large library of support functions that can easily define any complex limit-state function in a scripting FORTRAN-like syntax format. Its inverse probability analysis and sensitivities analysis capabilities make it a powerful design aid in any product cycle. Its precise numerical analysis engine is accurate enough to push the failure probabilities of a design to well below 10 (exp -50). UNIPASS is equipped with advanced artificial intelligence that is designed to handle systems with an essentially unlimited number of random variables with ease and efficiency. Its modular arrangement allows you to tailor an analysis to the desired level of accuracy and efficiency. The depth and comprehensiveness of UNIPASS are built upon the decades of experience and expertise of industry leaders including Boeing Aircraft, NASA and the DoD. Its rich content also makes UNIPASS a valuable instructional tool for random processes and probabilistic mechanics. The topics include: 1) Reliability in AvSP; 2) Role of UNIPASS in AvSP; and 3) Examples. This paper is in viewgraph form.

  8. Forskere i norske avisers dekning av skole

    Full Text Available Skolen er stadig i medienes søkelys, og i denne artikkelen ser vi nærmere på hvordan forskere bidrar med sine fagkunnskaper i skoledebatten i mediene. Den problemstillingen vi ønsker å besvare, er: Hvilken rolle har forskere i norske avisers dekning av skole? For å svare på dette har vi gjort en analyse av samtlige artikler om skole i VG, Bergens Tidende og Aftenposten i 2013. Resultatene viser at det forekommer en navngitt forsker i ca. 12 % av avisenes artikler om skole (209 av 1712 artikler. Det er imidlertid forskjell mellom avisene, og i VG opptrer det forskere i ca. 24 % av artiklene om skole, mens andelen både i Aftenposten og BT er ca. 11 %. Undersøkelsen viser videre at det er mange forskere som får mulighet til å uttale seg om skole i disse tre avisene, men det store flertallet av disse uttaler seg kun én gang. Vi fant også at forskere ofte uttaler seg om rammene for skolens undervisningsvirksomhet, og sjelden om det som foregår i klasserommene. Resultatene av vår empiriske undersøkelse stemmer i stor grad overens med hovedtendensene i tidligere studier av forskere i media, noe som indikerer at forskernes rolle i norske avisers skoledekning ikke skiller seg markant ut fra den rollen forskere har i media generelt. Våre resultater peker imidlertid på én viktig forskjell: Forskere ser ut til å være uvanlig godt synlige i norske avisers dekning av skole.Nøkkelord: skoleforskning, media, forskningsformidlingAbstractSchool is a frequently debated topic in the media, and this article investigates how researchers contribute with their knowledge in this media debate. The research question is: What characterizes researcher participation in Norwegian newspaper coverage of school? To answer this question we have analyzed all articles about school in the Norwegian newspapers VG, Bergens Tidende and Aftenposten during 2013. The results show that there is a named researcher in about 12 % of the newspaper articles about school

    2007-09-01

    Full Text Available El golpe de ariete puede generar consecuencias severas en la integridad de las tuberías, y debido a ello, la si-mulación es un requisito esencial para asegurar el correcto diseño y operación de los sistemas de distribución de agua. En este sentido, el artículo pretende demostrar la importancia de los métodos numéricos en la resolución de este tipo de problemas. Para la simulación numérica del fenómeno se desarrolló un código en Scilab3 que permite representar la propagación de las ondas de presión haciendo uso del método de las características, aplicado a un caso clásico de la literatura. Este método emplea un esquema de diferencias finitas para resolver las ecuaciones de masa y momento. En el artículo se presentan las ecuaciones que gobiernan el problema desde el punto de vista numérico, se analiza el comportamiento del fenómeno y finalmente, se realiza una comparación entre los resultados obtenidos por la vía numérica y la solución teórica.

    Directory of Open Access Journals (Sweden)

    Helle Margrete Meltzer

    2009-11-01

    Full Text Available  SAMMENDRAGI perioden 1999-2001 vil det bli gjennomført tre kostholdsundersøkelser som til sammen skal kartlegge konsum avmatvarer med betydning for inntaket av miljøgifter i Norge, fortrinnsvis kadmium, kvikksølv, PCB og dioksiner.Disse giftene finnes hovedsakelig i krabbe, flatfisk, skjell, gjedde og abbor, lever eller nyre fra vilt og viltvoksendesopp. Fordi gjennomsnittskonsumet er lavt, spørres det ikke spesifikt om disse matvarene i landsdekkende kostholdsundersøkelsersom 'Norkost'. Hensikten med studien er å kunne gi en bedre beskrivelse av eksponeringsfordelingeni befolkningen med tanke på miljøgifter. Fordelingen er antakelig skjev, dvs. et stort antall personerventes å ha et lavt inntak og noen få personer ventes å ha et relativt høyt inntak av de undersøkte stoffene. Eventuelleukjente risikogrupper vil kunne avdekkes, og det er av stor interesse å undersøke hvor stor eksponeringen i deutsatte gruppene er.Del A av undersøkelsen er landsdekkende og omfatter en postal frekvensundersøkelse til 10 000 tilfeldig valgtepersoner mellom 18 og 79 år. Del B omfatter en postal frekvensundersøkelse til 6000 tilfeldig valgte personer i sekskommuner, der tre er kystkommuner og tre er innlandskommuner. Kommunene blir valgt ut fra kjennskap til godtilgang på de aktuelle matvarene. Vi antar at der tilgangen på matvarene er god, er konsumet høyere. Del C avundersøkelsen vil omfatte høykonsumenter av aktuelle matvarer, valgt fra del B av undersøkelsen. Dette vil være endybdestudie der analyser av miljøgifter i blod, hår og urin også skal inngå.Undersøkelsen er den første i sitt slag her til lands og vi kjenner ikke til at tilsvarende studier er gjort i andreland. Hensikten med artikkelen er å gi en beskrivelse av undersøkelsen i en tidlig fase av gjennomføringen.Meltzer HM, Bergsten C, Stene LC, Stigum H, Wiborg ML, Lund-Larsen K, Alexander J. Consumption ofcontaminated foods – Description of a dietary survey

    Full Text Available Landscape is a part of every individual’s sense of being.  However, one cannot deny the special relationships that Indigenous peoples maintain with places they have inhabited since the beginning of creation.  These places are deeply imbued with meaning, and are sites of personal and community identity.  In addition, these places are legal in nature.  They teach Indigenous people about their legal obligations – to each other, their ancestors and the natural world.  This paper examines the connection between land and law for the Hul’qumi’num Mustimuhw, a group of Island Hul’qumi’num speaking First Nations, located on southeastern Vancouver Island.  It discusses how lands within Indigenous territories can be transformed into legal landscapes, when considered in relation to place, time and experience.  It also examines specific legal landscapes within the Hul’qumi’num territory and explores the laws and regulations that reside within and flow from them.  Through this paper, one can gain insight into how these places inform the Hul’qumi’num lgal tradition and impart important teachings to the Hul’qumi’num Mustimuhw about the nature of their relationship and their obligations to particular places and inhabitants of those places.   Le paysage fait intrinsèquement partie de l’identité de chacun. Cependant, nul ne saurait nier les liens spéciaux que les peuples autochtones ont noués avec les endroits qu’ils habitent depuis le début de la création. Ces endroits revêtent un sens tout particulier pour eux et sont des lieux auxquels ils s’identifient, tant sur le plan personnel que sur le plan communautaire. De plus, ces endroits ont acquis une grande signification juridique. Ils enseignent aux Autochtones en quoi consistent leurs obligations juridiques envers eux-mêmes, envers leurs ancêtres et envers la nature. Dans ce texte, l’auteur se penche sur la relation qui existe entre le territoire et la loi pour

    Full Text Available Medisinsk forskning har ført til store framskritt de siste tiårene. Det er investert mye mer ressurser på basalforskning og klinisk forskning enn på å utvikle og evaluere metoder for å sikre at pasientene får nytte av forskningen. Formålet med implementeringsforskning er å redusere gapet mellom forskning og praksis, ved å utvikle og evaluere tiltak som kan sikre at behandlingen som pasientene mottar er kunnskapsbasert, at den er omsorgsfull og av god kvalitet.I denne artikkelen gjør vi rede for hva implementering og implementeringsforskning er. Vi belyser historikken til denne unge vitenskapen, og illustrerer mangfoldet i de faglige tilnærmingene og begrepene som brukes om det å få forskning brukt i praksis. Det finnes en rekke teorier om endring av atferd, både på individnivå og på organisatorisk nivå. Teoriene er imidlertid i liten grad testet empirisk, særlig når det gjelder å endre atferd i helsetjenesten.Systematiske oversikter over metodisk gode studier er den beste kilden til informasjon om effekt av implementeringstiltak. The Cochrane Effective Practice and Organisation of Care Group (EPOC er en viktig kilde for slike oversikter. De systematiske oversiktene som er utarbeidet på dette feltet viser at passive dissemineringstiltak har begrenset effekt, mens mer aktive tiltak kan ha liten til moderat effekt. Det er ofte betydelig variasjon i effekt på tvers av studiene. Det er derfor viktig å få bedre kunnskap om hvilke faktorer som kan forklare slike forskjeller i effekt.Vi gir eksempler på norske implementeringsstudier, og refererer bidrag fra forskere ved Kunnskapssenteret. Implementeringsforskningen kan, hvis den lykkes, sikre pasientene bedre behandling.Flottorp S, Aakhus E. Implementation research: science for improving practice.

    Full Text Available Cet article présente une réflexion sur les enjeux portés par le numérique dans l’évolution des objets, des méthodes et des sujets de recherche en sciences humaines et sociales et plus particulièrement en Sciences de l’information et de la communication. À partir d’une définition du média numérique dans sa relation à l’hypertexte et à l’hypermédia, et d’une analyse du rôle transversal des technologies de l’information et de la communication dans les médiations, il est proposé de réfléchir la convergence entre humanités et numérique en fonction du besoin de transdisciplinarité qui en résulte. Les transformations holistiques provoquées par les technologies numériques requièrent des approches complexes des activités humaines, devant inclure des théorisations multiples auxquelles ne peut répondre un seul champ disciplinaire. Les évolutions des problématiques en SIC font potentiellement d’elles une discipline pivot pouvant (se concentrer (sur les relations entre les sciences de l’ingénieur et les sciences humaines. La discussion se termine sur une projection des problématiques transversales à venir autour de la localisation et de l’accès aux données numériques, des mémoires collectives et des traces numériques, des frontières numériques. La prégnance des technologies numériques dans les activités humaines confirme également l’importance d’engager une réflexion de fond sur « les éthiques » de la société de l’information.This paper presents a discussion on the challenges brought out by digital technologies. Objects, methods and research topics in the humanities and social sciences, and especially in information and communication sciences (ICS, have been impacted by digital media.

  20. A full-fledged micromagnetic code in fewer than 70 lines of NumPy

    International Nuclear Information System (INIS)

    Abert, Claas; Bruckner, Florian; Vogler, Christoph; Windl, Roman; Thanhoffer, Raphael; Suess, Dieter

    2015-01-01

    We present a complete micromagnetic finite-difference code in fewer than 70 lines of Python. The code makes a large use of the NumPy library and computes the exchange field by finite differences and the demagnetization field with a fast convolution algorithm. Since the magnetization in finite-difference micromagnetics is represented by a multi-dimensional array and the NumPy library features a rich interface for this data structure, the code we present is an ideal starting point for the development of novel algorithms. - Highlights: • A very concise but complete micromagnetic code written in Python is presented. • An introduction to finite-difference micromagnetics is provided. • The code is a perfect starting point for the development of novel algorithms

  3. Cocteau au cirque: The Poetics of Parade and "Le Numéro Barbette"

    Directory of Open Access Journals (Sweden)

    2003-01-01

    Full Text Available Parade (1917 was a joint effort production with libretto by Jean Cocteau music by Erik Satie, decor, costumes, and curtain by Pablo Picasso, and choreography by Léonide Massine. It was not only Cocteau's first truly original work, but, as Pierre Gobin contends, Parade is central to an understanding of the structures that would inform all of his subsequent work. Equally central, proposes Lydia Crowson, is Cocteau's July 1926 Nouvelle Revue Française article on "Le Numéro Barbette." The essay on the transvestite striptease trapezist Barbette offers a poetics of the theater that will have changed little by the time of his last play, L'Impromptu du Palais Royal . The underlying system structuring the Coctelian poetics perceived by Gobin and Crowson is perhaps neither in Parade nor in "Le Numéro Barbette" alone, but in both as they propose a poetics of Coctelian art as illusion, and reference and actualize the semantic register of a particular signifying system: not the fairground parade , as contends Gobin and other critics, but the circus and circus culture. But while Parade and "Le Numéro Barbette" share a circus-related theme, the circus does not function merely as a metaphor. Each work in a different way appropriates and promotes rather the circus's revolutionary orientation toward space, its creation of "real" time, and its undermining of social signifying systems, in particular those pertaining to race and gender. The circus space is like that of dreams in that it permits the irresolution and co-existence of the sort of contradictions cited by Guillaume Apollinaire in the celebrated program notes for Parade , and produced by Barbette in his aerial number. This he learned from the circus. Parade and "Le Numéro Barbette" are indeed pivotal texts in the formulation of Cocteau's very twentieth-century poétique .

  9. The SPF27 homologue Num1 connects splicing and kinesin 1-dependent cytoplasmic trafficking in Ustilago maydis.

    Directory of Open Access Journals (Sweden)

    Nikola Kellner

    2014-01-01

    Full Text Available The conserved NineTeen protein complex (NTC is an integral subunit of the spliceosome and required for intron removal during pre-mRNA splicing. The complex associates with the spliceosome and participates in the regulation of conformational changes of core spliceosomal components, stabilizing RNA-RNA- as well as RNA-protein interactions. In addition, the NTC is involved in cell cycle checkpoint control, response to DNA damage, as well as formation and export of mRNP-particles. We have identified the Num1 protein as the homologue of SPF27, one of NTC core components, in the basidiomycetous fungus Ustilago maydis. Num1 is required for polarized growth of the fungal hyphae, and, in line with the described NTC functions, the num1 mutation affects the cell cycle and cell division. The num1 deletion influences splicing in U. maydis on a global scale, as RNA-Seq analysis revealed increased intron retention rates. Surprisingly, we identified in a screen for Num1 interacting proteins not only NTC core components as Prp19 and Cef1, but several proteins with putative functions during vesicle-mediated transport processes. Among others, Num1 interacts with the motor protein Kin1 in the cytoplasm. Similar phenotypes with respect to filamentous and polar growth, vacuolar morphology, as well as the motility of early endosomes corroborate the genetic interaction between Num1 and Kin1. Our data implicate a previously unidentified connection between a component of the splicing machinery and cytoplasmic transport processes. As the num1 deletion also affects cytoplasmic mRNA transport, the protein may constitute a novel functional interconnection between the two disparate processes of splicing and trafficking.

  11. Pollen transmission of asparagus virus 2 (AV-2) may facilitate mixed infection by two AV-2 isolates in asparagus plants.

    2014-09-01

    Asparagus virus 2 (AV-2) is a member of the genus Ilarvirus and thought to induce the asparagus decline syndrome. AV-2 is known to be transmitted by seed, and the possibility of pollen transmission was proposed 25 years ago but not verified. In AV-2 sequence analyses, we have unexpectedly found mixed infection by two distinct AV-2 isolates in two asparagus plants. Because mixed infections by two related viruses are normally prevented by cross protection, we suspected that pollen transmission of AV-2 is involved in mixed infection. Immunohistochemical analyses and in situ hybridization using AV-2-infected tobacco plants revealed that AV-2 was localized in the meristem and associated with pollen grains. To experimentally produce a mixed infection via pollen transmission, two Nicotiana benthamiana plants that were infected with each of two AV-2 isolates were crossed. Derived cleaved-amplified polymorphic sequence analysis identified each AV-2 isolate in the progeny seedlings, suggesting that pollen transmission could indeed result in a mixed infection, at least in N. benthamiana.

    1987-01-01

    Concepts and techniques of human reliability have been developed and are used mostly in probabilistic risk assessment. For this, the major application of human reliability assessment has been to identify the human errors which have a significant effect on the overall safety of the system and to quantify the probability of their occurrence. Some of the major issues within human reliability studies are reviewed and it is shown how these are applied to the assessment of human failures in systems. This is done under the following headings; models of human performance used in human reliability assessment, the nature of human error, classification of errors in man-machine systems, practical aspects, human reliability modelling in complex situations, quantification and examination of human reliability, judgement based approaches, holistic techniques and decision analytic approaches.

    In this study, we demonstrated that a derivative of imidazole, AVS-1357, is a novel skin-whitening compound. AVS-1357 was found to significantly inhibit melanin production in a dose-dependent manner; however, it did not directly inhibit tyrosinase. Furthermore, we found that AVS-1357 induced prolonged activation of extracellular signal-regulated kinase (ERK) and Akt, while it downregulated microphthalmia-associated transcription factor (MITF) and tyrosinase. It has been reported that the activation of ERK and/or Akt is involved in melanogenesis. Therefore, we examined the effects of AVS-1357 on melanogenesis in the absence or presence of PD98059 (a specific inhibitor of the ERK pathway) and/or LY294002 (a specific inhibitor of the Akt pathway). PD98059 dramatically increased melanogenesis, whereas LY294002 had no effect. Furthermore, PD98059 attenuated AVS-1357 induced ERK activation, as well as the downregulation of MITF and tyrosinase. These findings suggest that the effects of AVS-1357 occur via downregulation of MITF and tyrosinase, which is caused by AVS-1357-induced prolonged ERK activation. Taken together, our results indicate that AVS-1357 has the potential as a new skin whitening agent.

    Since the arrival of the Dawn spacecraft at 4 Vesta on July 16, 2011 the Visible and InfraRed Imaging Spectrometer (VIR) has acquired hyperspectral images of Vesta's surface, which enable to characterize Vesta's mineralogical composition in the wavelength range from 0.25 to 5.1µm. As part of the analysis of Vesta's surface composition the science team is preparing a series of 15 quadrangle maps showing the results derived from the spectroscopic analysis of the VIR and FC color data. We present preliminary results of the spectroscopic analysis achieved for the quadrangles Av-2 (Belicia) and Av-3 (Caparronia), which show Vesta's surface between 21°N - 66° N°, 0° - 90°E and 90° - 180° E, respectively. These results are based on the analysis of the combination of the visible albedo, spectral parameters including the position, depth of the pyroxene absorptions, as well as color ratio composites using the VIR channels centering at 749nm/438nm (Red), 749nm/917nm (Green) and 438nm/749nm (Blue). Vesta's rotation axis, however, is tilted ~29° with respect to its orbital plane. Since Dawn arrived during northern winter, portions of Vesta north of ~45° N are dominated by extended shadows or have not yet been imaged due to permanent night. Thus, limited FC color or VIR hyperspectral data have been available for the quadrangles Av-2 and Av-3. The illuminated parts are dominated by a heavily-cratered northern terrain with ancient troughs and grooves and named after the prominent relatively large impact craters Belicia (~37°N/48°E) and Caparronia (~36°N/167°E). Numerous impact craters of different size, morphology, and state of surface degradation are apparent. Most spectral variations are strongly affected by the extreme illumination conditions, making the analysis of albedo variations and spectral signatures rather difficult. Their interpretation thus remains. Nevertheless, VIR spectra show clear evidence of Vesta's surface composition similar to those of HED

  20. Cofactor requirement of HpyAV restriction endonuclease.

    Directory of Open Access Journals (Sweden)

    Siu-Hong Chan

    Full Text Available BACKGROUND: Helicobacter pylori is the etiologic agent of common gastritis and a risk factor for gastric cancer. It is also one of the richest sources of Type II restriction-modification (R-M systems in microorganisms. PRINCIPAL FINDINGS: We have cloned, expressed and purified a new restriction endonuclease HpyAV from H. pylori strain 26695. We determined the HpyAV DNA recognition sequence and cleavage site as CCTTC 6/5. In addition, we found that HpyAV has a unique metal ion requirement: its cleavage activity is higher with transition metal ions than in Mg(++. The special metal ion requirement of HpyAV can be attributed to the presence of a HNH catalytic site similar to ColE9 nuclease instead of the canonical PD-X-D/EXK catalytic site found in many other REases. Site-directed mutagenesis was carried out to verify the catalytic residues of HpyAV. Mutation of the conserved metal-binding Asn311 and His320 to alanine eliminated cleavage activity. HpyAV variant H295A displayed approximately 1% of wt activity. CONCLUSIONS/SIGNIFICANCE: Some HNH-type endonucleases have unique metal ion cofactor requirement for optimal activities. Homology modeling and site-directed mutagenesis confirmed that HpyAV is a member of the HNH nuclease family. The identification of catalytic residues in HpyAV paved the way for further engineering of the metal binding site. A survey of sequenced microbial genomes uncovered 10 putative R-M systems that show high sequence similarity to the HpyAV system, suggesting lateral transfer of a prototypic HpyAV-like R-M system among these microorganisms.

    Sediment and overlying water samples were collected at 10 sampling stations at Xinan Creek, a tidal river in Pearl River Delta, and analyzed for physical and chemical characteristics as well as microbial incicators, in order to reveal the main factors dominating the spatial distribution of acid volatile sulfide (AVS). The effects of Eh, SRB OC and TS on the spatial distribution of AVS were investigated and the impact of AVS on the toxicity of heavy metals in the studied area was evaluated. The results showed that the range of AVS was 0.207-41.453 micromol x g(-1), with an average of 6.684 micromol x g(-1), which is relatively high compared to the results in other studies. The AVS value of the surface layer was higher than the bottom layer in 5 stations. The AVS values in both the surface layer and the bottom layer were highly variable, the coefficients of variation being 93.61% and 153.09% , respectively. The analytical results revealed that TS was the factor with the greatest impact on the spatial distribution of AVS, and the order was TS > OC > Eh > SRB. Potential ecological risk of heavy metals existed in 60% of the smpling stations based on the value of Sigma (SEM5-AVS), however, with the criterion of [Sigma(SEM5-AVS)]/foc, none of them had inacceptable ecological risk. Furthermore, in terms of single species of heavy metals, there was certain risk of toxic effect for all the five heavy metals (Cd, Ni, Cu, Zn and Pb). The above mentioned results will provide valuable data for the in-depth study of the formation mechanism of AVS and helpful reference for environmental impact assessment and scientific rehabilitation of heavy metals in polluted rivers.

    L. R. Marconcin

    Full Text Available A utilização de estruturas mistas está cada vez mais presente nas obras de Engenharia Civil. As vigas mistas, em particular, são estruturas compostas por dois materiais, um perfil metálico, situado em região predominantemente tracionada, e uma seção de concreto, situada em região predominantemente comprimida, ligados entre si através de dispositivos metálicos denominados de conectores de cisalhamento. As funções prin- cipais dos conectores são: permitir o trabalho solidário da laje-viga, restringir o escorregamento longitudinal e o deslocamento vertical na interface dos elementos e, absorver forças de cisalhamento. Nesse contexto, apresentam-se neste trabalho, modelos numéricos tridimensionais de vigas mistas aço-concreto, com a finalidade de simular o seu comportamento estrutural, enfatizando a interface laje-viga. As simulações foram feitas através do software ANSYS versão 10.0, que tem como base o Método de Elementos Finitos. Os resultados obtidos foram comparados com os previstos por norma e com referências encontradas na revisão bibliográfica, verificando-se que a modelagem numérica é uma ferramenta válida para a análise de vigas mistas aço-concreto.

    A 60-year-old man presented with recurrent abdominal pain and weight loss for 6 months. Abdominal imaging showed a large vascular lesion in the head and neck of pancreas suggestive of arteriovenous malformation (AV malformation). Endoscopic ultrasound was done which showed features of AV malformation with no evidence of pancreatic malignancy. Surgery was planned for definitive treatment of malformation. Digital subtraction angiography with angioembolization was done prior to surgery to reduce vascularity of the lesion. He recovered after a pylorus preserving pancreaticoduodenectomy. Histopathology of the resected specimen confirmed the pancreatic AV malformation. There has been no recurrence at 2 years of follow-up.

  19. Reliability calculations

    International Nuclear Information System (INIS)

    Petersen, K.E.

    1986-03-01

    Risk and reliability analysis is increasingly being used in evaluations of plant safety and plant reliability. The analysis can be performed either during the design process or during the operation time, with the purpose to improve the safety or the reliability. Due to plant complexity and safety and availability requirements, sophisticated tools, which are flexible and efficient, are needed. Such tools have been developed in the last 20 years and they have to be continuously refined to meet the growing requirements. Two different areas of application were analysed. In structural reliability probabilistic approaches have been introduced in some cases for the calculation of the reliability of structures or components. A new computer program has been developed based upon numerical integration in several variables. In systems reliability Monte Carlo simulation programs are used especially in analysis of very complex systems. In order to increase the applicability of the programs variance reduction techniques can be applied to speed up the calculation process. Variance reduction techniques have been studied and procedures for implementation of importance sampling are suggested. (author)

    Psi4NumPy demonstrates the use of efficient computational kernels from the open-source Psi4 program through the popular NumPy library for linear algebra in Python to facilitate the rapid development of clear, understandable Python computer code for new quantum chemical methods, while maintaining a relatively low execution time. Using these tools, reference implementations have been created for a number of methods, including self-consistent field (SCF), SCF response, many-body perturbation theory, coupled-cluster theory, configuration interaction, and symmetry-adapted perturbation theory. Furthermore, several reference codes have been integrated into Jupyter notebooks, allowing background, underlying theory, and formula information to be associated with the implementation. Psi4NumPy tools and associated reference implementations can lower the barrier for future development of quantum chemistry methods. These implementations also demonstrate the power of the hybrid C++/Python programming approach employed by the Psi4 program.

    The question of reliability technology using quantified techniques is considered for systems and structures. Systems reliability analysis has progressed to a viable and proven methodology whereas this has yet to be fully achieved for large scale structures. Structural loading variants over the half-time of the plant are considered to be more difficult to analyse than for systems, even though a relatively crude model may be a necessary starting point. Various reliability characteristics and environmental conditions are considered which enter this problem. The rare event situation is briefly mentioned together with aspects of proof testing and normal and upset loading conditions. (orig.)

    Aksfusariose er en vanlig sykdom på korn forårsaket av flere ulike Fusarium-arter. En Fusarium-infeksjon på akset gir tap av avling i tillegg til en reduksjon i kvaliteten på kornet. Reduksjonen i kvalitet skjer i hovedsak gjennom produksjon av en rekke toksiske metabolitter (mykotoksiner) som kan være en helserisiko for både dyr og mennesker. I de senere årene har det vært økt fokus på Fusarium og mykotoksiner i korn både i Norge og i store deler av verden. En årsak til det...

    We tested the predictions of the dynamic reweighting model (DRM) of audiovisual (AV) speech integration, which posits that spectrotemporally reliable (informative) AV speech stimuli induce a reweighting of processing from low-level to high-level auditory networks. This reweighting decreases sensitivity to acoustic onsets and in turn increases tolerance to AV onset asynchronies (AVOA). EEG was recorded while subjects watched videos of a speaker uttering trisyllabic nonwords that varied in spectrotemporal reliability and asynchrony of the visual and auditory inputs. Subjects judged the stimuli as in-sync or out-of-sync. Results showed that subjects exhibited greater AVOA tolerance for non-blurred than blurred visual speech and for less than more degraded acoustic speech. Increased AVOA tolerance was reflected in reduced amplitude of the P1-P2 auditory evoked potentials, a neurophysiological indication of reduced sensitivity to acoustic onsets and successful AV integration. There was also sustained visual alpha band (8-14 Hz) suppression (desynchronization) following acoustic speech onsets for non-blurred vs. blurred visual speech, consistent with continuous engagement of the visual system as the speech unfolds. The current findings suggest that increased spectrotemporal reliability of acoustic and visual speech promotes robust AV integration, partly by suppressing sensitivity to acoustic onsets, in support of the DRM's reweighting mechanism. Increased visual signal reliability also sustains the engagement of the visual system with the auditory system to maintain alignment of information across modalities. © 2018 Federation of European Neuroscience Societies and John Wiley & Sons Ltd.

    Want to buy some reliability? The question would have been unthinkable in some markets served by the natural gas business even a few years ago, but in the new gas marketplace, industrial, commercial and even some residential customers have the opportunity to choose from among an array of options about the kind of natural gas service they need--and are willing to pay for. The complexities of this brave new world of restructuring and competition have sent the industry scrambling to find ways to educate and inform its customers about the increased responsibility they will have in determining the level of gas reliability they choose. This article discusses the new options and the new responsibilities of customers, the needed for continuous education, and MidAmerican Energy Company's experiment in direct marketing of natural gas

  20. The role of AV and VV optimization for CRT

    Directory of Open Access Journals (Sweden)

    William W. Brabham, M.D.

    2013-06-01

    Full Text Available Cardiac resynchronization therapy is an effective therapy for patients with left ventricular systolic dysfunction and a ventricular conduction delay; however, approximately 30% of patients do not experience significant clinical improvement with this treatment. Modern devices allow individualized programming of the AV delay and VV offset, which offer the possibility of improving clinical response rates with optimized programming. AV and VV delay optimization techniques have included echocardiography, device-based algorithms, and several other novel noninvasive techniques. While an acute improvement in hemodynamic function has been clearly demonstrated with optimized device settings, long-term clinical benefit is limited. In the majority of cases, an empiric AV delay with simultaneous biventricular or left ventricular pacing is adequate. The value of optimization of these intervals in “non-responders” still requires further investigation.

    2013-06-01

    Full Text Available I denne artikkelen ser vi på hvilken type informasjon elever i 7. klasse vektlegger for å konstruere en sammenhengende oppsummering av fire til dels motstridende tekster. Elever møter ofte flere tekster om samme tema – multiple tekster – og vi trenger økt kunnskap om hvordan de leser slike tekster. Elevene leste fire ulike tekster om en sykkelulykke. Tekstene presenterte informasjon som var delvis sammenfallende på tvers av alle tekstene, og delvis motstridende informasjon som innebar at enkelte tekster ga ulike beskrivelser av hendelsesforløpet. Vi testet elevenes ordavkodingsferdigheter, fikk dem til å fylle ut et spørreskjema om lesevaner og vi innhentet elevenes resultater på Nasjonal leseprøve. Etter lesing ba vi elevene gi en oppsummering av sykkelulykken. Elevene gjenga relativt mer sammenfallende informasjon enn motstridende informasjon. Gode resultater på Nasjonal leseprøve ser ut til å ha en sammenheng med elevenes ferdigheter i å konstruere en sammenhengende forståelse av de fire tekstene. Elever som oppga å lese mye på Internett hadde imidlertid fått med mindre av informasjonen som var felles for de fire tekstene i sine oppsummeringer. Vi fant også en negativ sammenheng mellom fritidslesing på Internett og resultatene fra Nasjonal leseprøve. Samlet sett indikerer resultatene at når elevene skal skape sammenheng mellom flere delvis motstridende tekster, så blir sammenfallende informasjon vektlagt mer enn motstridende informasjon. Dessuten ser det ut til at de elevene som bruker mest fritid til å lese på Internett, sliter mer med å sammenfatte innholdet i de fire tekstene enn de andre elevene.

    Rydén, Michaéla; Nilsson, Thina

    2013-01-01

    Användandet av betong som ersättare för stål vid produktionen av vindkraftverkstorn har ökat den senaste tiden. Betongtorn är betydligt billigare än ståltorn men problem som sprickbildningar, frostsprängningar och följaktligen armeringskorrosion har uppstått bl a på grund av vibrationer från rotorn. I fundamentet i vindkraftverk kan ovan nämnda problem också uppstå och det uppfyller således inte alltid funktionskraven. Det här examensarbetet undersöker möjligheten att eliminera dessa problem ...

  1. Parallel Algorithm of Geometrical Hashing Based on NumPy Package and Processes Pool

    Directory of Open Access Journals (Sweden)

    Klyachin Vladimir Aleksandrovich

    2015-10-01

    Full Text Available The article considers the problem of multi-dimensional geometric hashing. The paper describes a mathematical model of geometric hashing and considers an example of its use in localization problems for the point. A method of constructing the corresponding hash matrix by parallel algorithm is considered. In this paper an algorithm of parallel geometric hashing using a development pattern «pool processes» is proposed. The implementation of the algorithm is executed using the Python programming language and NumPy package for manipulating multidimensional data. To implement the process pool it is proposed to use a class Process Pool Executor imported from module concurrent.futures, which is included in the distribution of the interpreter Python since version 3.2. All the solutions are presented in the paper by corresponding UML class diagrams. Designed GeomNash package includes classes Data, Result, GeomHash, Job. The results of the developed program presents the corresponding graphs. Also, the article presents the theoretical justification for the application process pool for the implementation of parallel algorithms. It is obtained condition t2 > (p/(p-1*t1 of the appropriateness of process pool. Here t1 - the time of transmission unit of data between processes, and t2 - the time of processing unit data by one processor.

  2. Analysis of AVS-penogram in 3000 impotent patients

    Minn, Young Guy; Choi, Hyung Ki [Yonsei University College of Medicine, Seoul (Korea, Republic of)

    1994-09-01

    Audio visual simulation penogram(AVS-penogram) is used as a screening method for evaluation of erectile dysfunction. In this study, 3000 patients were evaluated from Dec. 1986 to Dec. 1992 and finally diagnosed by comprehensive diagnostic methods. The patients were classified according to AVS-penogram curves into 4 types and correlated with the patient`s final diagnosis. For 800 patients who were evaluated with combined AVS-penogram and NPT monitoring, compatibility ratios between psychogenic and organic group were compared. After correlating each of the curve type with the patients and comparing erotic and nocturnal erection, following results were obtained. 1. The mean age of the patients was 41.25 years. 2. The overall rate of final diagnosis were 57.5%, 14.3%, 8.9% in psychogenic, arteriogenic and veogenic impotence. 3. Type I group was proved as psychogenic impotence in 87% of the patients. 4. Type IIA group was proved as organic impotence in 79% of the patients and most of them had neurogenic and arteriogenic impotence. 5. Type IIB group was proved as psychogenic impotence in 51%, organic impotence in 49% of the patients. Among the organic impotence group, most of them had arteriogenic, venogenic and neurogenic impotence. The difference of both group was statically insignificant. 6. Type IIC group was proved as psychogenic impotence in 39%, organic impotence in 61% of the patients. Further studies are needed for sub-classification of both groups. 7. The compatibility ratio of the AVS-penogram and NPTM was 85.9% in psychogenic group with normal finding in both tests and 44.7% in organic group with abnormal finding in both tests. In conclusion, AVS-penogram is a primary diagnostic method in screening impotent patients and type I is regarded as psychogenic impotence. In Type IIB and IIC, sub-classification of curve type is needed for differential diagnosis between psychogenic and organic impotence. (Abstract Truncated)

    Advanced Vitrification System (AVS) is commissioned for vitrification of high level waste (HLW) by using Joule heated ceramic melter first time in India. The HLW is generated in fuel reprocessing plant. For radiological surveillance of plant, Health Physics Unit (HPU) had installed 37 Area Gamma Monitors (AGM), 7 Continuous Air Monitors (CAM) and all types of personal contamination monitors. Exposure control is a major concern in operating plant. Therefore in addition to installed monitors, we have developed online remote radiation monitoring system to minimize exposures to the surveyor and operator. This also helped in volume reduction of secondary waste. The reliability and accuracy of the online monitoring system is confirmed by calibrating the system by comparing TLD and DRD readings and by theoretical analysis. In addition some modifications were carried in HP instruments to make them user friendly. This paper summarizes different kinds of remote radiological monitoring systems installed for online monitoring of Melter off Gas (MOG) filter, Hood filter, three exhaust filter banks, annulus air sampling and over pack monitoring in AVS. Our online remote monitoring system has helped the plant management to plan in advance for replacement of these filters, which resulted in considerable saving of collective dose. (author)

    Qu'est-ce que l'analyse numérique ? C'est un ensemble d'outils qui permet d'obtenir une solution numérique approchée d'un problème mathématique, lui-même modèle d'une question technique ou scientifique. Pourquoi étudier (et enseigner) l'analyse numérique conçue de cette manière ? N'est-il pas suffisant d'appuyer sur la touche «solve» d'une calculette pour résoudre une équation algébrique ? Si l'on veut vraiment utiliser un logiciel, pourquoi faire plus que d'appeler, à l'intérieur d'un logiciel de haut niveau, la fonction «solve» ? En réalité, il est toujours profitable de connaître le principe de fonctionnement des outils que l'on utilise afin de les employer au mieux et pour être conscient de leurs limites. De plus, il peut arriver qu'un programme, bien qu'immédiatement disponible, ne soit pas parfaitement adapté à l'usage prévu ; seul l'utilisateur bien informé pourra le modifier en connaissance de cause et étendre son domaine de validité.

Dans le cadre de leur travail minutieux de description des quipus, Ascher & Ascher ont observé que les chiffres incorporés dans les cordes de deux d’entre eux avaient un lien très précis. Pour que cela ait été possible, ces chiffres auraient dû être calculés grâce à la multiplication de chiffres entiers par des fractions ou des chiffres décimaux, ce qui semble aller bien au-delà des connaissances arithmétiques des Incas. La présente étude expose et commente l’interprétation graphique établie par les auteurs. Une nouvelle interprétation est proposée, selon laquelle les quipus étudiés contiennent une information se référant à des angles, et un modèle géométrique est proposé. On trouvera dans cet article toute l'information numérique nécessaire pour de nouvelles recherches. Dentro de su amplio trabajo de descripción de quipus, Ascher & Ascher observaron en dos de ellos que los números registrados en sus cuerdas cumplen una relación muy especial. Para que tal cosa ocurra, los números debieron haber sido obtenidos mediante la multiplicación de enteros por fracciones o por decimales, operaciones aparentemente fuera del alcance del conocimiento aritmético de los incas. En el presente trabajo se expone y se comenta la interpretación gráfica que elaboraron los autores mencionados.

    Full Text Available Norges Idrettsforbund og Olympiske og Paralympiske Komité (NIF har en uttalt målsetting om en åpen og inkluderende idrett. Hvordan kommer dette til uttrykk i den praktiske virksomheten? Denne artikkelen, som bygger på data fra en undersøkelse om likestilling og mangfold i den organiserte idretten (NIF, retter søkelyset mot arbeid med inklusjon av ungdom med minoritetsbakgrunn på ulike organisasjonsnivå i NIF: særforbund, idrettskretser og idrettslag. Datamaterialet er kvalitative intervju med representanter fra ulike organisasjonsnivå. Resultatene viser at NIFs overordnede politikk i varierende grad nedfelles i særforbundenes virksomhet, i idrettskretsene og i idrettslagene.

    Full Text Available Artikkelen tar utgangspunkt i tre observasjoner av en gutt på fire år som bruker iPad på fritiden. Den søker å synliggjøre de strategiene dette barnet velger for å skaffe seg tilgang til ulike medietekster, hvordan han leser og tolker dem, og den undersøker eventuelle spor av kritisk refleksjon hos barnet over disse tekstene. Teoretisk sett hviler den på en forståelse av mediekompetanse som en parallell prosess til utvikling av lese- og skrivekyndighet (literacy, og medieopplevelsene omtales som viktige møter med tekst. Artikkelen undersøker hvordan å lese medietekster kan legge et grunnlag for å utvikle en utvidet tekstkompetanse eller mediekompetanse. Konklusjonen legger vekt på motivasjon og lekenhet som barns primære inngang til medietekstene og som et grunnlag for å utvikle mediekompetanse (media literacy. The article is based on three observations of a four-year-old boy who uses the iPad in his spare time. It demonstrates the strategies that this boy applies to gain access to various media texts, and how he reads and interprets them. It also seeks to examine traces of critical reflection that he may demonstrate in relation to these texts. Theoretically, it rests on an understanding of media literacy as a parallel process to the development of literacy, and it seeks to demonstrate how reading media texts can create an important starting point for the development of media literacy. The Kindergarten practitioner’s role and opportunities to develop children's media literacy within a kindergarten context is a focus towards the end of the article. In conclusion, I argue that motivation and playfulness are important approaches to media texts and create an important foundation for the development of media literacy

    Full Text Available  SAMMENDRAGSpanskesyken var en verdensomspennende influensaepidemi som tok livet av minst 30 millioner mennesker,de fleste i løpet av noen få høstmåneder i 1918, men den strakk seg også inn i 1919. En siste svakbølge fant sted vinteren 1920. De første sporadiske tilfellene av spanskesyken i Norge oppsto i militærleirei begynnelsen av april 1918. Over tre måneder senere kom de første spredte tilfellene av det som skullevise seg å være starten på en ny stor influensapandemi. De første av disse oppsto i Kristiania, mest sannsynligetter smitteimport fra Skottland over Nordsjøen. Sommeren 1918 spredte spanskesyken seg raskt frasør til nord, fra kysten til innlandet innover fjordene, og fra de største byene og industrisentra via mindrebyer og andre tettsteder til landsbygda langs de viktigste ferdselsveiene. Da spanskesyken blusset opp igjenhøsten 1918 spredte den seg langsommere og trolig fra nord til sør, fortsatt fra kysten innover fjordene,men spredning fra byene langs kommunikasjonsveiene var mindre fremtredende. Vinteren 1918/19opptrådte influensaen spredt og sporadisk, tilsynelatende uten bestemt spredningsmønster og rekkefølge.Jernbanen, hurtigruten og automobilrutene spilte trolig en viktig rolle i spredningsprosessen, spesielt andrehalvår 1918.

    This study presents the development of an efficient procedure for covalently immobilizing collagen molecules on AVS-functionalized Ti-6Al-4V samples, and the assessment of the survival and proliferation of cells cultured on these substrates. Activated Vapor Silanization (AVS) is a versatile functionalization technique that allows obtaining a high density of active amine groups on the surface. A procedure is presented to covalently bind collagen to the functional layer using EDC/NHS as cross-linker. The covalently bound collagen proteins are characterized by fluorescence microscopy and atomic force microscopy and their stability is tested. The effect of the cross-linker concentration on the process is assessed. The concentration of the cross-linker is optimized and a reliable cleaning protocol is developed for the removal of the excess of carbodiimide from the samples. The results demonstrate that the covalent immobilization of collagen type I on Ti-6Al-4V substrates, using the optimized protocol, increases the number of viable cells present on the material. Consequently, AVS in combination with the carbodiimide chemistry appears as a robust method for the immobilization of proteins and, for the first time, it is shown that it can be used to enhance the biological response to the material.

    Full Text Available På et fotballag i overgangen mellom barne- og ungdomsfotballen er spilletid på fotballbanen under kamp både en knapp ressurs og en kilde til diskusjoner om fordeling. Spørsmålet som er utgangspunkt for denne artikkelen, er hvilke hensyn som bør tas når trener og lagleder skal fordele samlet spilletid på enkeltspillere. Er det viktigst å vinne fotballkampen, eller har det størst betydning å fordele spilletiden mest mulig likt mellom spillerne? Skal det tas hensyn til guttenes evner, motivasjon og preferanser? Er deres familiebakgrunn og personlighet av betydning? Diskusjonen baserer seg på en gjennomgang av ulike politiske rettferdighetsteorier for fordeling av knappe goder.Nøkkelord: rettferdighet, practice, fordelingsrettferdighet, diskursetikk, idrettsetikkEnglish summary: Minutes of justice: Distribution of time during football matches in a boys' teamDuring a football match, time for playing can be considered as a limited good. In this article the point of departure is the redistribution of time in a boys' football team in the transition phase between children and youth football. The questions are how and under which conditions time for playing should be distributed among the players. Is winning the game more important than trying to let every player play for an equal amount of time? Should the boys' talents, motivation, and preferences be considered while distributing time, or are family background and personality of importance? Different theories of political justice for the distribution of limited goods underpin the discussion of how to distribute the minutes of playing time during a football match.http://dx.doi.org/10.5324/eip.v4i1.1737

  1. Artificial vision support system (AVS(2)) for improved prosthetic vision.

    Science.gov (United States)

    Fink, Wolfgang; Tarbell, Mark A

    2014-11-01

    State-of-the-art and upcoming camera-driven, implanted artificial vision systems provide only tens to hundreds of electrodes, affording only limited visual perception for blind subjects. Therefore, real time image processing is crucial to enhance and optimize this limited perception. Since tens or hundreds of pixels/electrodes allow only for a very crude approximation of the typically megapixel optical resolution of the external camera image feed, the preservation and enhancement of contrast differences and transitions, such as edges, are especially important compared to picture details such as object texture. An Artificial Vision Support System (AVS(2)) is devised that displays the captured video stream in a pixelation conforming to the dimension of the epi-retinal implant electrode array. AVS(2), using efficient image processing modules, modifies the captured video stream in real time, enhancing 'present but hidden' objects to overcome inadequacies or extremes in the camera imagery. As a result, visual prosthesis carriers may now be able to discern such objects in their 'field-of-view', thus enabling mobility in environments that would otherwise be too hazardous to navigate. The image processing modules can be engaged repeatedly in a user-defined order, which is a unique capability. AVS(2) is directly applicable to any artificial vision system that is based on an imaging modality (video, infrared, sound, ultrasound, microwave, radar, etc.) as the first step in the stimulation/processing cascade, such as: retinal implants (i.e. epi-retinal, sub-retinal, suprachoroidal), optic nerve implants, cortical implants, electric tongue stimulators, or tactile stimulators.

Hyppigere forekomst av bivirkninger kan forklares delvis,men ikke fullstendig, av at kvinner som gruppe konsumerer oftere og flere legemidler. Videre har legemiddelbrukhos kvinner i mange tilfeller tilknytning til biologiske tilstander som menstruasjon, graviditetog menopause, og den øker med alderen. Det er viktig å ta i betraktning kulturelle forskjeller hoskvinner og menn som kan være med på å overestimere kjønnsforskjellene i bivirkningsforekomsten.Kvinner bruker helsevesenet hyppigere og rapporterer oftere bivirkninger. Høyere bivirkningsfrekvenshos kvinner kan også være resultat av at kvinner generelt får høyere dose per kg enn menn fordikvinner veier mindre.

    To give a help in the interpretation of cardiac cine-MR examination, the extent, shape, and timing of appearance of signal void regions near atrioventricular(A-V) valve prospectively evaluate in the healthy population. Using an axial gradient-echo technique with small flip angle, repetition time(TR) of 36 msec and echo time(TE) of 22 msec, 20 volunteers without known valvular abnormalities undertook cardiac cine-MR imaging including atrioventricular valve areas. Transient signal void was observed within the near the tricuspid(13/20 = 65%) and mitral valves(9/20 = 45%), respectively, which is so called {sup p}hysioloic atrioventricular valvular insufficiency{sup .} Eight subjects revealed the signal void areas near both tricuspid and mitral valves but, 5 subjects did not show any evidence of physiologic insufficiency. This physiologic condition does not extend more than 1 cm proximal to A-V valve plane and is generally observed only during early systole. Its morphology is semilunar or triangular configuration with the base to the valve plane in most cases of normal tricuspid insufficiency and small globular appearance in most cases of normal mitral insufficiency. Awareness of normal signal void areas near the A-V valve and their characteristics is critical in the interpretation of cardiac cine MR examinations and maybe helpful in the study of the normal cardiac physiology.

Using an axial gradient-echo technique with small flip angle, repetition time(TR) of 36 msec and echo time(TE) of 22 msec, 20 volunteers without known valvular abnormalities undertook cardiac cine-MR imaging including atrioventricular valve areas. Transient signal void was observed within the near the tricuspid(13/20 = 65%) and mitral valves(9/20 = 45%), respectively, which is so called p hysioloic atrioventricular valvular insufficiency . Eight subjects revealed the signal void areas near both tricuspid and mitral valves but, 5 subjects did not show any evidence of physiologic insufficiency. This physiologic condition does not extend more than 1 cm proximal to A-V valve plane and is generally observed only during early systole. Its morphology is semilunar or triangular configuration with the base to the valve plane in most cases of normal tricuspid insufficiency and small globular appearance in most cases of normal mitral insufficiency. Awareness of normal signal void areas near the A-V valve and their characteristics is critical in the interpretation of cardiac cine MR examinations and maybe helpful in the study of the normal cardiac physiology

    In 20 patients with known or suspected supratentorial arteriovenous malformations, an attempt was made to see how far CT angiography with 3-dimensional reconstructions is able to make a diagnosis and to differentiate the various components of the angioma. Spiral CT was performed following an intravenous bolus injection of 60-80 ml of iodine containing contrast medium. In all patients the diagnosis was confirmed by intra-arterial DSA of the vertebral vessels. In 13 patients, av malformations could be diagnosed following multiplanar 3-D reconstructions which agreed with the findings on DSA. The large supplying vessels, the nidus and the large draining veins could be defined with certainty. In 6 patients follow-up examination after embolisation was performed. The results could be demonstrated in three dimensions and the success of treatment could be documented unequivocally. CT angiography with 3-D reconstruction is able to supply important information in the majority of intracranial av malformations, both during initial investigation and following treatment. (orig.)

    Acid-volatile sulfides (AVS) formation and its role on trace metals bioavailability were studied in semi-arid mangroves. The semi-arid climatic conditions at the studied sites, marked by low rainfall and high evapotranspiration rates, clearly limited the AVS formation (AVS contents varied from 0.10 to 2.34μmolg -1 ) by favoring oxic conditions (Eh>+350mV). The AVS contents were strongly correlated with reactive iron and organic carbon (r=0.84; r=0.83 respectively), evidencing their dominant role for AVS formation under semi-arid conditions. On the other hand, the recorded ΣSEM/AVS values remained >1 evidencing a little control of AVS over the bioavailability of trace metals and, thus, its minor role as a sink for toxic metals.

    Full Text Available Cet article analyse l’incidence des modes de circulation de l’image sur les pratiques de la photographie de presse. L’exemple choisi est celui d’une photographie qui représente une femme au milieu des décombres d’Ishinomaki, image achetée par l’Agence France-Presse (AFP à un quotidien japonais, au lendemain du Tsunami de mars 2011. Reprise en couverture de nombreux journaux occidentaux, recadrée autour de la figure féminine, initialement saisie en plan large, cette photographie devient un portrait, rapidement désigné comme « la madone des décombres ». En décrivant les facteurs techniques, commerciaux et éditoriaux qui structurent le secteur de la photographie de presse, l’article interroge la mondialisation des standards visuels. Il s’agit de comprendre comment des phénomènes de stéréotypie visuelle apparaissent en lien avec le fonctionnement du marché de l’image numérique : l’auteur procède donc à une observation des logiciels utilisés par les journalistes de l’AFP, combinée à une analyse sémiotique des formats, légendes, commentaires sur l’image. Il apparaît que la mondialisation de la photographie de presse, qui repose sur des « syndications » internationales, modifie aussi le statut du photographe d’agence. Alors que les normes journalistiques pour le journalisme agencier préconisent l’effacement de l’auteur, les transformations de la photographie d’Ishinomaki sont le déclenchement d’un feuilleton médiatique, sur les réseaux sociaux comme dans les magazines occidentaux, dont le photographe lui-même devient le héros. L’AFP publie une semaine après le Tsunami une dépêche concernant l’histoire de cette image, dévoilant toutes sortes d’informations qui demeurent ordinairement inconnues du public : prix de vente de la photographie, nom du chef du bureau chargé de la collecte d’informations en Asie, identité du photographe.

    Florbetapir (AV-45) has been shown to be a reliable tool for assessing in vivo amyloid load in patients with Alzheimer's disease from the early stages. However, nonspecific white matter binding has been reported in healthy subjects as well as in patients with Alzheimer's disease. To avoid this issue, cortical quantification might increase the reliability of AV-45 PET analyses. In this study, we compared two quantification methods for AV-45 binding, a classical method relying on PET template registration (route 1), and a MRI-based method (route 2) for cortical quantification. We recruited 22 patients at the prodromal stage of Alzheimer's disease and 17 matched controls. AV-45 binding was assessed using both methods, and target-to-cerebellum mean global standard uptake values (SUVr) were obtained for each of them, together with SUVr in specific regions of interest. Quantification using the two routes was compared between the clinical groups (intragroup comparison), and between groups for each route (intergroup comparison). Discriminant analysis was performed. In the intragroup comparison, differences in uptake values were observed between route 1 and route 2 in both groups. In the intergroup comparison, AV-45 uptake was higher in patients than controls in all regions of interest using both methods, but the effect size of this difference was larger using route 2. In the discriminant analysis, route 2 showed a higher specificity (94.1 % versus 70.6 %), despite a lower sensitivity (77.3 % versus 86.4 %), and D-prime values were higher for route 2. These findings suggest that, although both quantification methods enabled patients at early stages of Alzheimer's disease to be well discriminated from controls, PET template-based quantification seems adequate for clinical use, while the MRI-based cortical quantification method led to greater intergroup differences and may be more suitable for use in current clinical research.

    Scientific audiovisual media such as videos of research, interactive displays or computer animations has become an important part of scientific communication and education. Dynamic phenomena can be described better by audiovisual media than by words and pictures. For this reason, scientific videos help us to understand and discuss environmental phenomena more efficiently. Moreover, the creation of scientific videos is easier than ever, thanks to mobile devices and open source editing software. Video-clips, webinars or even the interactive part of a PICO are formats of scientific audiovisual media used in the Geosciences. This type of media translates the location-referenced Science Communication such as environmental interpretation into computed-based Science Communication. A new way of Science Communication is video abstracting. A video abstract is a three- to five-minute video statement that provides background information about a research paper. It also gives authors the opportunity to present their research activities to a wider audience. Since this kind of media have become an important part of scientific communication there is a need for reliable infrastructures which are capable of managing the digital assets researchers generate. Using the reference of the usecase of video abstracts this paper gives an overview over the activities by the German National Library of Science and Technology (TIB) regarding publishing and linking audiovisual media in a scientifically sound way. The German National Library of Science and Technology (TIB) in cooperation with the Hasso Plattner Institute (HPI) developed a web-based portal (av.tib.eu) that optimises access to scientific videos in the fields of science and technology. Videos from the realms of science and technology can easily be uploaded onto the TIB|AV Portal. Within a short period of time the videos are assigned a digital object identifier (DOI). This enables them to be referenced, cited, and linked (e.g. to the

    This article demonstrates how the influential scholar Edgar Dale, alongside a generation of educational technologists, helped build an essential place for AV materials and pedagogical methods in the American classroom. It also shows that, for decades, the Payne Fund philanthropy supported multimedia research agendas that shaped ideas about teaching and technology, far beyond involvement in their famed studies on motion pictures and children in the 1930s. With his writings and research programs, Dale advanced concepts of media experience and systematicity, which came to be understood as common sense to the information society. In so doing he was a leading contributor to the discursive and ideological structure of our age of technological and informational abundance.

    Wolfram C Poller

    Full Text Available Optimization of the AV-interval (AVI in DDD pacemakers improves cardiac hemodynamics and reduces pacemaker syndromes. Manual optimization is typically not performed in clinical routine. In the present study we analyze the prevalence of E/A wave fusion and A wave truncation under resting conditions in 160 patients with complete AV block (AVB under the pre-programmed AVI. We manually optimized sub-optimal AVI.We analyzed 160 pacemaker patients with complete AVB, both in sinus rhythm (AV-sense; n = 129 and under atrial pacing (AV-pace; n = 31. Using Doppler analyses of the transmitral inflow we classified the nominal AVI as: a normal, b too long (E/A wave fusion or c too short (A wave truncation. In patients with a sub-optimal AVI, we performed manual optimization according to the recommendations of the American Society of Echocardiography.All AVB patients with atrial pacing exhibited a normal transmitral inflow under the nominal AV-pace intervals (100%. In contrast, 25 AVB patients in sinus rhythm showed E/A wave fusion under the pre-programmed AV-sense intervals (19.4%; 95% confidence interval (CI: 12.6-26.2%. A wave truncations were not observed in any patient. All patients with a complete E/A wave fusion achieved a normal transmitral inflow after AV-sense interval reduction (mean optimized AVI: 79.4 ± 13.6 ms.Given the rate of 19.4% (CI 12.6-26.2% of patients with a too long nominal AV-sense interval, automatic algorithms may prove useful in improving cardiac hemodynamics, especially in the subgroup of atrially triggered pacemaker patients with AV node diseases.

    TIME VARIATION OF AV AND RV FOR TYPE Ia SUPERNOVAE BEHIND NON-UNIFORM INTERSTELLAR DUST ABSTRACT We investigate the time variation of the visual extinction, AV, and the total-to-selective extinction ratio, RV, resulting from interstellar dust in front of an expanding photospheric disk of a type Ia supernova (SN Ia). We simulate interstellar dust clouds according to a power law power spectrum and produce extinction maps that either follow a pseudo-Gaussian distribution or a lognormal distribution. The RV maps are produced through a correlation between AV and RV. With maps of AV and RV generated in each case (pseudo-Gaussian and lognormal), we then compute the effective AV and RV for a SN as its photospheric disk expands behind the dust screen. We find for a small percentage of SNe the AV and RV values can vary by a large factor from day to day in the first 40 days after explosion.

    Sediment treatment and sediment storage may alter sediment toxicity, and consequently biotic response. Purpose of our study was to combine these three aspects (treatment-toxicity-biotic response) in one integrated approach. We used Acid Volatile Sulfide (AVS) concentrations as a proxy of the disturbance of the sediment. AVS and Simultaneously Extracted Metal (SEM) concentrations were compared to bioassay responses with the freshwater benthic macroinvertebrate Asellus aquaticus. Storage conditions and sediment treatment affected AVS but not SEM levels. AVS can be used as a proxy for sediment disturbance. The best way to pretreat the sediment for use in a bioassay in order to maintain initial AVS conditions was to sample the sediment with an Ekman grab, immediately store it in a jar without headspace, and freeze it as soon as possible. In a survey using seven different sediments, bioassay responses of A. aquaticus were correlated with SEM and AVS characteristics.

    Computers, consumer, and communications are converging and fusing. The key device in homes in the near future will be an audiovisual hard disk drive (AV-HDD). The reason is that there is no other AV cash memory with high capacity, high speed, and a low price than the HDD. Fuji Electric has early started developing an AV magnetic hard disk, a core-functional element of the AV-HDD, to take the initiative in the market. This paper describes the state of plastic medium development, which is regarded as a next-generation strategic commodity. (author)

  9. Open-Loop Audio-Visual Stimulation (AVS): A Useful Tool for Management of Insomnia?

    Science.gov (United States)

    Tang, Hsin-Yi Jean; Riegel, Barbara; McCurry, Susan M; Vitiello, Michael V

    2016-03-01

    Audio Visual Stimulation (AVS), a form of neurofeedback, is a non-pharmacological intervention that has been used for both performance enhancement and symptom management. We review the history of AVS, its two sub-types (close- and open-loop), and discuss its clinical implications. We also describe a promising new application of AVS to improve sleep, and potentially decrease pain. AVS research can be traced back to the late 1800s. AVS's efficacy has been demonstrated for both performance enhancement and symptom management. Although AVS is commonly used in clinical settings, there is limited literature evaluating clinical outcomes and mechanisms of action. One of the challenges to AVS research is the lack of standardized terms, which makes systematic review and literature consolidation difficult. Future studies using AVS as an intervention should; (1) use operational definitions that are consistent with the existing literature, such as AVS, Audio-visual Entrainment, or Light and Sound Stimulation, (2) provide a clear rationale for the chosen training frequency modality, (3) use a randomized controlled design, and (4) follow the Consolidated Standards of Reporting Trials and/or related guidelines when disseminating results.

    A high reliability is a very important goal for most particle accelerators. The biennial Accelerator Reliability Workshop covers topics related to the design and operation of particle accelerators with a high reliability. In order to optimize the over-all reliability of an accelerator one needs to gather information on the reliability of many different subsystems. While a biennial workshop can serve as a platform for the exchange of such information, the authors aimed to provide a further channel to allow for a more timely communication: the Particle Accelerator Reliability Forum [1]. This contribution will describe the forum and advertise it’s usage in the community.

    NASA's Dawn spacecraft arrived at the asteroid 4 Vesta in July 2011 and is now collecting imaging and spectroscopic data during its one-year orbital mission. The maps we present are based on information obtained by the Visible and Infrared Mapping Spectrometer VIR-MS and the multi-color Framing Camera FC. VIR covers the wavelength range between 0.25 to 5.1 µm while FC covers the range 0.4 to 1.0 µm. The VIR instrument has a significant higher spectral resolution than FC but the latter achieves higher spatial resolution data. As part of the geological and mineralogical analysis of the surface, a series of 15 quadrangles have been defined covering the entire surface of Vesta. We report about the mapping results of quadrangle Av-6 (Gegania) and Av-7 (Lucaria). The Gegania quadrangle is dominated by old craters showing no ejecta blankets and rays while several small fresh craters do. The most obvious geologic features are a set of equatorial troughs, a group of three ghost craters of similar diameter (~57 km), an ejecta mantling of the Gegania crater and three smaller craters showing bright and dark ejecta rays. The quadrangle contains two main geologic units: 1) the northern cratered trough terrain and 2) the equatorial ridge and trough terrain. The quadrangle shows moderate variation in Band II center wavelength and Band II depth. FC color ratio variations of some recent craters and their ejecta are linked to the bright and dark material. The bright material is possibly excavated eucritic material while the dark material could be remnants of a CM2 impator(s) or an excavated subsurface layer of endogenic origin. The most prominent geologic features in the Lucaria quadrangle are the 40 km long hill Lucaria Tholus, a set of equatorial troughs, some relatively fresh craters with bright and dark material and mass wasting. The quadrangle contains three main geologic units: 1) the northern cratered trough terrain, 2) the equatorial ridge and trough terrain, and 3) the

    Full Text Available Formålet med denne studien var å undersøke elevers oppfatninger av norsklærerens tilbakemeldingspraksis i skriftlig norsk. På bakgrunn av omfattende internasjonal forskning innen feltet ‘Vurdering for læring’ (VfL er det i denne studien utviklet teoridrevne hypoteser som testes ved å analysere et datasett fra to videregående skoler. Hypotesene er at elevene oppfatter lærers tilbakemelding som mer nyttig hvis den 1 retter seg mot målet med opplæringen, 2 gir elevene informasjon via en forklaring eller instruks om hvordan de skal komme nærmere målet og 3 at lærer legger til rette for bruk av tilbakemeldingen. Strukturell likningsmodellering (SEM av resultater fra en spørreundersøkelse blant elever (N = 213 er brukt som metode til å estimere forholdet mellom de fire latente variablene kriterier, forklaring, bruk og nytte (avhengig variabel. SEM er brukt fordi metoden egner seg til å undersøke sammenhenger i komplekse datasett. Funn er at elevene oppfatter at hvis lærer forklarer hvordan de kan forbedre seg, er dette positivt statistisk assosiert med opplevd nytte. Et mer overraskende funn er at lærerens tilrettelegging for bruk av tilbakemeldinger ikke er signifikant assosiert med opplevd nytte. Resultatene blir diskutert i artikkelen.

    Junctional ectopic tachycardia (JET) is a postoperative complication with a mortality rate of up to 14% after surgery for congenital heart disease. This study evaluated the risk factors of JET and explored the association of postoperative temporary third degree atrioventricular (AV) block and the occurrence of JET. Data were collected retrospectively from 1158 patients who underwent surgery for congenital heart disease. The overall incidence of JET was 2.8%. Temporary third degree AV block occurred in 1.6% of cases. Permanent third degree AV block requiring pacemaker implantation occurred in 1% of cases. In all, 56% of patients with JET had temporary AV block (P < 0.001), whereas no case of postoperative JET was reported in patients with permanent AV block (P = 0.56). temporary third degree AV block did not suffer from JET. A correlation between temporary third degree AV block and postoperative JET could be observed. The risk factors identified for JET include younger age groups at the time of surgery, longer aortic cross clamping time and surgical procedures in proximity to the AV node

    Energy Technology Data Exchange (ETDEWEB)

    Smith, Mark A.; Atcitty, Stanley

    2009-12-01

    This report provides the DOE and industry with a general process for analyzing power electronics reliability. The analysis can help with understanding the main causes of failures, downtime, and cost and how to reduce them. One approach is to collect field maintenance data and use it directly to calculate reliability metrics related to each cause. Another approach is to model the functional structure of the equipment using a fault tree to derive system reliability from component reliability. Analysis of a fictitious device demonstrates the latter process. Optimization can use the resulting baseline model to decide how to improve reliability and/or lower costs. It is recommended that both electric utilities and equipment manufacturers make provisions to collect and share data in order to lay the groundwork for improving reliability into the future. Reliability analysis helps guide reliability improvements in hardware and software technology including condition monitoring and prognostics and health management.

    The federal government advocates the practice of routinely providing an after-visit summary (AVS) to patients after each office-based visit as an element of stage 1 meaningful use. A significant potential benefit of the AVS is improved patient engagement achieved by enabling patients and family members to better understand and retain key health information. The methodology for this study was a mixed-methods pilot study to examine, through the perspectives of adult primary care patients, how relevant and actionable data can be better formatted in the AVS. Results of this study suggest that the goal of the AVS to serve as a communication tool to engage and support patients is frequently not being met. Further study is needed to understand, from the viewpoints of patients and providers, what barriers are keeping them from optimally providing and using the information on the AVS.

Rutinemessig vil SRI undersøkedet politiet rekvirerer, men prøvene lagres inntil to år etter at de er analysert. Ved supplerende analyse i ettertidkan man således få et mer fullstendig bilde av hva mistenkte, påvirkede bilførere hadde i kroppen da de avgaprøve. I den foreliggende undersøkelsen ble 1197 prøver fra februar og september 1993 analysert på et bredtspekter av andre rusmidler foruten alkohol, uavhengig av hva politiets mistanke hadde vært. Vi fant da at alkoholalene var til stede i 55 % av prøvene, andre rusmidler alene i 16%, både alkohol og andre rusmidler i 14%, mensverken alkohol eller andre rusmidler ble påvist i 15% av prøvene.

    Full Text Available Det er en utbredt oppfatning at det økende prestasjonskravet i toppfotball fører til en svekkelse av moral og fair play-holdninger. Men hvordan tenker toppfotballspillere i forhold til ulike dilemmaer som oppstår på banen, og er det forskjeller mellom toppfotballspillere og spillere på lavere nivå?  For å avklare dette gjennomførte vi en empirisk undersøkelse der vi intervjuet spillere og trener i én toppklubb og én breddeklubb. Vi var interessert i to hovedproblemstillinger:  1 Hva tenker fotballspillere på ulike prestasjonsnivå om etikk og moralske dilemmaer i fotball? 2 Hvilke faktorer påvirker spillerne, direkte og indirekte, i deres vurderinger og handlinger? Resultatene fra undersøkelsen viser at det er store forskjeller mellom de to prestasjonsnivåene. Spillerne på breddenivået føler generelt et større ansvar for å opptre ærlig på banen enn hva som er tilfelle på toppnivået. Vi fant 4 spesifikke faktorer i toppfotballen som bidrar til umoralsk opptreden. For det første opplever spillerne en forventning om at de prioriterer resultat foran fair play. For det andre bidrar tilstedeværelsen av supportere på kamper til en slik prioritering. For det tredje vil handlinger som er i strid med fair play signaliseres som akseptable internt i miljøet, selv om de ofte signaliseres som uakseptable overfor media og omverdenen. For det fjerde kan spillere oppleve det som vanskelig å gå i mot trenerens oppfordringer til en pragmatisk og resultatfokusert opptreden.Nøkkelord: moral, etikk, fair play, footballEnglish summary: How morally do football players think? – an empirical study of moral dilemmas in elite footballIt is a common view that the increasing focus on achievement and success in elite football leads to a weakening of moral and fair play attitudes.

    Full Text Available Vurdering av andrespråkselevers språkkompetanse og språkutvikling er en sentral del av læreres arbeid, og forskning har vist at dette er en utfordring for skolene. Det er stor variasjon i vurderingsformer, og skolene mangler ofte vurderingskompetanse. På bakgrunn av dette utarbeidet Utdanningsdirektoratet i 2007 vurderingsverktøyet Kartleggingsmateriell. Språkkompetanse i grunnleggende norsk for språklige minoriteter. Materiellet er utarbeidet blant annet med referanse til Common European Framework of Reference for Languages (CEFR. I artikkelen redegjør vi for en undersøkelse der målet var å finne ut hvorvidt dette kartleggingsmateriellet er hensiktsmessig for å vurdere andrespråkselevers språkkompetanse. Hoveddataene er innhentet gjennom kasusstudier ved tre grunnskoler, der vi intervjuet skoleledelse og lærere samt observerte kartleggingssituasjoner og klasseromsundervisning. Kasusstudiene ble senere fulgt opp av to spørreundersøkelser, én til de samme skolene, og én til et større antall skoler for å få bredere innsikt i kartleggingspraksis og skolers oppfatninger av denne formen for vurdering. Undersøkelsen viser at flere av informantene mener verktøyet kan bidra til mer tilpasset og systematisk andrespråkopplæring og bedre vurdering av andrespråkselevenes språkkompetanse. Samtidig er det utfordringer knyttet til å bruke vurderingsverktøyet, dette skyldes blant annet mangelfull kompetanse i skolen når det gjelder andrespråkstilegnelse og vurdering av elevenes språkkompetanse. Det er ikke tidligere forsket på bruk av et slikt konkret kartleggingsverktøy i norsk grunnskole. Undersøkelsen kan gi et bidrag til økt kunnskap om vurdering av andrespråkskompetanse og tilpasset undervisning for andrespråksinnlærere.

    1993-11-01

    In this article, we looked at some decisions that apply to the design of reliable computer systems. We began with a discussion of several terms such as testability, then described some systems that call for highly reliable hardware and software. The article concluded with a discussion of methods that can be used to achieve higher reliability in computer systems. Reliability and fault tolerance in computers probably will continue to grow in importance. As more and more systems are computerized, people will want assurances about the reliability of these systems, and their ability to work properly even when sub-systems fail.

    Sediment treatment and sediment storage may alter sediment toxicity, and consequently biotic response. Purpose of our study was to combine these three aspects (treatment-toxicity-biotic response) in one integrated approach. We used Acid Volatile Sulfide (AVS) concentrations as a proxy of the disturbance of the sediment. AVS and Simultaneously Extracted Metal (SEM) concentrations were compared to bioassay responses with the freshwater benthic macroinvertebrate Asellus aquaticus. Storage conditions and sediment treatment affected AVS but not SEM levels. AVS can be used as a proxy for sediment disturbance. The best way to pretreat the sediment for use in a bioassay in order to maintain initial AVS conditions was to sample the sediment with an Ekman grab, immediately store it in a jar without headspace, and freeze it as soon as possible. In a survey using seven different sediments, bioassay responses of A. aquaticus were correlated with SEM and AVS characteristics. - Change in AVS is a good proxy for sediment disturbance and combined with SEM it can be used as a suitable predictor for biotic effects of sediment contamination.

    Full Text Available Three object-oriented implementations of a prototype solver of the advection equation are introduced. The presented programs are based on Blitz++ (C++, NumPy (Python and Fortran's built-in array containers. The solvers constitute implementations of the Multidimensional Positive-Definite Advective Transport Algorithm (MPDATA. The introduced codes serve as examples for how the application of object-oriented programming (OOP techniques and new language constructs from C++11 and Fortran 2008 allow to reproduce the mathematical notation used in the literature within the program code. A discussion on the tradeoffs of the programming language choice is presented. The main angles of comparison are code brevity and syntax clarity (and hence maintainability and auditability as well as performance. All performance tests are carried out using free and open-source compilers. In the case of Python, a significant performance gain is observed when switching from the standard interpreter (CPython to the PyPy implementation of Python. Entire source code of all three implementations is embedded in the text and is licensed under the terms of the GNU GPL license.

    Full Text Available Le développement des techniques d’information et de communication a conduit la SNCF à développer une stratégie commerciale numérique vis-à-vis de tous ses segments de clientèle. S’appuyant sur le cas du secteur Sud Loire Océan, l’article montre que le développement des services d’information à la clientèle en temps réel a paradoxalement servi d’alibi pour laisser la qualité du service ferroviaire régional TER se dégrader, ce qui a eu pour conséquence une baisse sensible du trafic. Cet exemple montre que l’impact sociétal des TIC n’est pas conforme à celui escompté car il favorise l’émergence d’une culture de l’approximation et de l’improvisation.

    2009-11-01

    Full Text Available  SAMMENDRAGLangsom vektøkning gjennom livet inntil kroppsmasseindeks (KMI 27 ser ikke ut til å gi særlige negative utfallmht. total dødelighet. En økning på ! 20 kg fra 18 års alder er trolig negativt – det samme er vektøkning ut fra enhøy utgangsvekt. Selv om mange studier finner økt dødelighet hos yngre og middelaldrende personer med KMI > 27,er det foreløpig ingen studier som har vist at vektreduksjon blant friske overvektige personer gir økt levetid. Flerestudier viser tvert imot en assosiasjon mellom vektreduksjon og økt dødelighet. Heller ikke studier som prøver åbegrense analysene til personer med frivillig vekttap, finner redusert dødelighet etter vektreduksjon blant friskeovervektige individer. Noen få studier har vist redusert dødelighet blant overvektige personer med etablertesykdommer eller høy risiko for hjerte-karsykdom og diabetes. Når det gjelder sykelighet har de fleste studier entenikke funnet noen assosiasjon mellom vektreduksjon og sykelighet, eller funnet økt sykelighet. Unntaket er diabetes,der vekttap i enkelte studier samvarierer med redusert sykelighet. Det er i mange studier funnet sammenheng mellomvekttap og økt risiko for lårhalsbrudd og gallesten. De fleste studier har imidlertid vist at moderat vektreduksjon(vekttap på opp til 10% fører til redusert blodtrykk, forbedret glukosekontroll, redusert kolesterolnivå, forbedretdyslipidemi, forbedret lungefunksjon, bedre søvnkvalitet og redusert søvnapnè. Moderat vekttap vil også kunnelindre leddsmerter. Dette tilsynelatende paradoks diskuteres i artikkelen – bl.a. drøftes de metodeproblemer som erinnebygget i mange av studiene. Fordi det har vist seg vanskelig for personer med kraftig overvekt å redusere vektenpermanent – og fordi resultatene mht. helseeffektene av vektreduksjon er usikre, bør hovedinnsatsen settes inn iforhold til å forebygge overvekt/fedme overfor enkeltpersoner med potensielle problemer.

    The objectives of the study were to determine the validity and reliability of peak velocity (PV), average velocity (AV), peak power (PP) and average power (AP) measurements were made using a linear position transducer. Validity was assessed by comparing measurements simultaneously obtained using the Tendo Weightlifting Analyzer Systemi and T-Force Dynamic Measurement Systemr (Ergotech, Murcia, Spain) during two resistance exercises, bench press (BP) and full back squat (BS), performed by 71 trained male subjects. For the reliability study, a further 32 men completed both lifts using the Tendo Weightlifting Analyzer Systemz in two identical testing sessions one week apart (session 1 vs. session 2). Intraclass correlation coefficients (ICCs) indicating the validity of the Tendo Weightlifting Analyzer Systemi were high, with values ranging from 0.853 to 0.989. Systematic biases and random errors were low to moderate for almost all variables, being higher in the case of PP (bias ±157.56 W; error ±131.84 W). Proportional biases were identified for almost all variables. Test-retest reliability was strong with ICCs ranging from 0.922 to 0.988. Reliability results also showed minimal systematic biases and random errors, which were only significant for PP (bias -19.19 W; error ±67.57 W). Only PV recorded in the BS showed no significant proportional bias. The Tendo Weightlifting Analyzer Systemi emerged as a reliable system for measuring movement velocity and estimating power in resistance exercises. The low biases and random errors observed here (mainly AV, AP) make this device a useful tool for monitoring resistance training. Key points This study determined the validity and reliability of peak velocity, average velocity, peak power and average power measurements made using a linear position transducer The Tendo Weight-lifting Analyzer Systemi emerged as a reliable system for measuring movement velocity and power.

    Reliability techniques have been developed subsequently as a need of the diverse engineering disciplines, nevertheless they are not few those that think they have been work a lot on reliability before the same word was used in the current context. Military, space and nuclear industries were the first ones that have been involved in this topic, however not only in these environments it is that it has been carried out this small great revolution in benefit of the increase of the reliability figures of the products of those industries, but rather it has extended to the whole industry. The fact of the massive production, characteristic of the current industries, drove four decades ago, to the fall of the reliability of its products, on one hand, because the massively itself and, for other, to the recently discovered and even not stabilized industrial techniques. Industry should be changed according to those two new requirements, creating products of medium complexity and assuring an enough reliability appropriated to production costs and controls. Reliability began to be integral part of the manufactured product. Facing this philosophy, the book describes reliability techniques applied to electronics systems and provides a coherent and rigorous framework for these diverse activities providing a unifying scientific basis for the entire subject. It consists of eight chapters plus a lot of statistical tables and an extensive annotated bibliography. Chapters embrace the following topics: 1- Introduction to Reliability; 2- Basic Mathematical Concepts; 3- Catastrophic Failure Models; 4-Parametric Failure Models; 5- Systems Reliability; 6- Reliability in Design and Project; 7- Reliability Tests; 8- Software Reliability. This book is in Spanish language and has a potentially diverse audience as a text book from academic to industrial courses. (author)

    Operating reactor events such as the TMI accident and the Salem automatic-trip failures raised the concern that during a plant's operating lifetime the reliability of systems could degrade from the design level that was considered in the licensing process. To address this concern, NRC is sponsoring the Operational Safety Reliability Research project. The objectives of this project are to identify the essential tasks of a reliability program and to evaluate the effectiveness and attributes of such a reliability program applicable to maintaining an acceptable level of safety during the operating lifetime at the plant

    Morphine-induced glial proinflammatory responses have been documented to contribute to tolerance to opioid analgesia. Here, we examined whether drugs previously shown to suppress glial proinflammatory responses can alter other clinically relevant opioid effects; namely, withdrawal or acute analgesia. AV411 (ibudilast) and minocycline, drugs with distinct mechanisms of action that result in attenuation of glial proinflammatory responses, each reduced naloxone-precipitated withdrawal. Analysis of brain nuclei associated with opioid withdrawal revealed that morphine altered expression of glial activation markers, cytokines, chemokines, and a neurotrophic factor. AV411 attenuated many of these morphine-induced effects. AV411 also protected against spontaneous withdrawal-induced hyperactivity and weight loss recorded across a 12-day timecourse. Notably, in the spontaneous withdrawal study, AV411 treatment was delayed relative to the start of the morphine regimen so to also test whether AV411 could still be effective in the face of established morphine dependence, which it was. AV411 did not simply attenuate all opioid effects, as co-administering AV411 with morphine or oxycodone caused three-to-five-fold increases in acute analgesic potency, as revealed by leftward shifts in the analgesic dose response curves. Timecourse analyses revealed that plasma morphine levels were not altered by AV411, suggestive that potentiated analgesia was not simply due to prolongation of morphine exposure or increased plasma concentrations. These data support and extend similar potentiation of acute opioid analgesia by minocycline, again providing converging lines of evidence of glial involvement. Hence, suppression of glial proinflammatory responses can significantly reduce opioid withdrawal, while improving analgesia.

    The limitations of manned airborne meteorological measurements led to a new unmanned system, the Meteorological Mini-UAV (M{sup 2}AV), recently developed by the Institute of Aerospace Systems, Technical University of Braunschweig. The task was to develop, test and verify a meteorological sensor package as payload for an already available carrier aircraft, the UAV 'Carolo T200'. Thereby the limitations in size and mass had to be respected. The M{sup 2}AV is capable of performing turbulence and wind vector measurements within the atmospheric boundary layer and permits very short measurement cycles as an economic supplement during meteorological campaigns. The article gives details on the technical items. Results from meteorological data sets measured by the M{sup 2}AV are used for data quality assessment. In October 2005 the M{sup 2}AV participated in the meteorological field experiment 'LAUNCH 2005' in Lindenberg near Berlin. The M{sup 2}AV data were compared with lidar and sodar/RASS measurements. Furthermore, an in situ comparison of temperature, humidity and wind vector data with the helicopter-borne turbulence probe Helipod was analysed and gave information about the M{sup 2}AV data quality.

    Full Text Available Congenital heart defect (CHD is the most common cause of death from congenital anomaly. Among several candidate epigenetic mechanisms, DNA methylation may play an important role in the etiology of CHDs. We conducted a genome-wide DNA methylation analysis using an Illumina Infinium 450k human methylation assay in a cohort of 24 newborns who had aortic valve stenosis (AVS, with gestational-age matched controls. The study identified significantly-altered CpG methylation at 59 sites in 52 genes in AVS subjects as compared to controls (either hypermethylated or demethylated. Gene Ontology analysis identified biological processes and functions for these genes including positive regulation of receptor-mediated endocytosis. Consistent with prior clinical data, the molecular function categories as determined using DAVID identified low-density lipoprotein receptor binding, lipoprotein receptor binding and identical protein binding to be over-represented in the AVS group. A significant epigenetic change in the APOA5 and PCSK9 genes known to be involved in AVS was also observed. A large number CpG methylation sites individually demonstrated good to excellent diagnostic accuracy for the prediction of AVS status, thus raising possibility of molecular screening markers for this disorder. Using epigenetic analysis we were able to identify genes significantly involved in the pathogenesis of AVS.

    Young, William F; Stanson, Anthony W

    2009-01-01

    Adrenal venous sampling (AVS) is the criterion standard to distinguish between unilateral and bilateral adrenal disease in patients with primary aldosteronism. The keys to successful AVS include appropriate patient selection, careful patient preparation, focused technical expertise, defined protocol, and accurate data interpretation. The use of AVS should be based on patient preferences, patient age, clinical comorbidities, and the clinical probability of finding an aldosterone-producing adenoma. AVS is optimally performed in the fasting state in the morning. AVS is an intricate procedure because the right adrenal vein is small and may be difficult to locate - the success rate depends on the proficiency of the angiographer. The key factors that determine the successful catheterization of both adrenal veins are experience, dedication and repetition. With experience, and focusing the expertise to 1 or 2 radiologists at a referral centre, the AVS success rate can be as high as 96%. A centre-specific, written protocol is mandatory. The protocol should be developed by an interested group of endocrinologists, radiologists and laboratory personnel. Safeguards should be in place to prevent mislabelling of the blood tubes in the radiology suite and to prevent sample mix-up in the laboratory.

    1989-01-01

    Improved design techniques are needed to achieve high reliability at minimum cost. This is especially true of space systems where lifetimes of many years without maintenance are needed and severe mass limitations exist. Reliability must be designed into these systems from the start. Techniques are now being explored to structure a formal design process that will be more complete and less expensive. The intent is to integrate the best features of design, reliability analysis, and expert systems to design highly reliable systems to meet stressing needs. Taken into account are the large uncertainties that exist in materials, design models, and fabrication techniques. Expert systems are a convenient method to integrate into the design process a complete definition of all elements that should be considered and an opportunity to integrate the design process with reliability, safety, test engineering, maintenance and operator training. 1 fig

  9. A Study of Subseasonal Predictability of the Atmospheric Circulation Low-frequency Modes based on SL-AV forecasts

    Kruglova, Ekaterina; Kulikova, Irina; Khan, Valentina; Tischenko, Vladimir

    2017-04-01

    The subseasonal predictability of low-frequency modes and the atmospheric circulation regimes is investigated based on the using of outputs from global Semi-Lagrangian (SL-AV) model of the Hydrometcentre of Russia and Institute of Numerical Mathematics of Russian Academy of Science. Teleconnection indices (AO, WA, EA, NAO, EU, WP, PNA) are used as the quantitative characteristics of low-frequency variability to identify zonal and meridional flow regimes with focus on control distribution of high impact weather patterns in the Northern Eurasia. The predictability of weekly and monthly averaged indices is estimated by the methods of diagnostic verification of forecast and reanalysis data covering the hindcast period, and also with the use of the recommended WMO quantitative criteria. Characteristics of the low frequency variability have been discussed. Particularly, it is revealed that the meridional flow regimes are reproduced by SL-AV for summer season better comparing to winter period. It is shown that the model's deterministic forecast (ensemble mean) skill at week 1 (days 1-7) is noticeably better than that of climatic forecasts. The decrease of skill scores at week 2 (days 8-14) and week 3( days 15-21) is explained by deficiencies in the modeling system and inaccurate initial conditions. It was noticed the slightly improvement of the skill of model at week 4 (days 22-28), when the condition of atmosphere is more determined by the flow of energy from the outside. The reliability of forecasts of monthly (days 1-30) averaged indices is comparable to that at week 1 (days 1-7). Numerical experiments demonstrated that the forecast accuracy can be improved (thus the limit of practical predictability can be extended) through the using of probabilistic approach based on ensemble forecasts. It is shown that the quality of forecasts of the regimes of circulation like blocking is higher, than that of zonal flow.

    One can also speak of reliability with respect to materials. While for reliability of components the MTBF (mean time between failures) is regarded as the main criterium, this is replaced with regard to materials by possible failure mechanisms like physical/chemical reaction mechanisms, disturbances of physical or chemical equilibrium, or other interactions or changes of system. The main tasks of the reliability analysis of materials therefore is the prediction of the various failure reasons, the identification of interactions, and the development of nondestructive testing methods.

    A lot of results in mechanical design are obtained from a modelisation of physical reality and from a numerical solution which would lead to the evaluation of needs and resources. The goal of the reliability analysis is to evaluate the confidence which it is possible to grant to the chosen design through the calculation of a probability of failure linked to the retained scenario. Two types of analysis are proposed: the sensitivity analysis and the reliability analysis. Approximate methods are applicable to problems related to reliability, availability, maintainability and safety (RAMS)

    Neurons from the rostral ventrolateral medulla (RVLM) directly activate sympathetic pre-ganglionic neurons in the spinal cord. Hypertensive responses and sympathetic activation produced by different stimuli are strongly affected by lesions of the preoptic periventricular tissue surrounding the anteroventral third ventricle (AV3V region). Therefore, in the present study, we investigated the effects of acute (1 day) and chronic (15 days) electrolytic lesions of the AV3V region on the pressor responses produced by injections of the excitatory amino acid L-glutamate into the RVLM of unanesthetized rats. Male Holtzman rats with sham or electrolytic AV3V lesions and a stainless steel cannula implanted into the RVLM were used. The pressor responses produced by injections of L-glutamate (1, 5 and 10 nmol/100 nl) into the RVLM were reduced 1 day (9 +/- 4, 39 +/- 6 and 37 +/- 4 mm Hg, respectively) and 15 days after AV3V lesions (13 +/- 6, 39 +/- 4 and 43 +/- 4 mm Hg, respectively, vs. sham lesions: 29 +/- 3, 50 +/- 2 and 58 +/- 3 mm Hg, respectively). Injections of L-glutamate into the RVLM in sham or AV3V-lesioned rats produced no significant change in the heart rate (HR). Baroreflex bradycardia and tachycardia produced by iv phenylephrine or sodium nitroprusside, respectively, and the pressor and bradycardic responses to chemoreflex activation with iv potassium cyanide were not modified by AV3V lesions. The results suggest that signals from the AV3V region are important for sympathetic activation induced by L-glutamate into the RVLM.

    Full Text Available This article focuses on a study that took place in the school year of 2002/2003. The study is about the different games of power and interests moved by the actors from one of the administrative structure of the public basic schools: the pedagogic board. The implementation of a legal system of administrating schools by the Decree Law nr 115-A/98 brought changes to the pedagogic board composition. Thus, the plurality of actors, due to both its legal composition and to the creation of the schools grouping, gave a more complexity to this board. From a case study in a schools’ grouping, we pretend, on one hand, to analyse different powers among the pedagogic board members. On the other hand, to reflect on how the teachers see the participation of the different actors of this board. The data obtained from the investigation shows the existence of different relationships of power among the members of this board. The decisions, the procedures and practises adopted by the grouping mirror, above all, a greater predominance of the teachers’ interests of the 2nd and 3rd cycles comparing with the kindergartens and teachers of the 1st cycle, developing, in this way, cycles’ interests which may fragile dynamics connoted with the democratic logics

    1975-01-01

    Experience has shown that reliability assessments can play an important role in the early design and subsequent operation of technological systems where reliability is at a premium. The approaches to and techniques for such assessments, which have been outlined in the paper, have been successfully applied in variety of applications ranging from individual equipments to large and complex systems. The general approach involves the logical and systematic establishment of the purpose, performance requirements and reliability criteria of systems. This is followed by an appraisal of likely system achievment based on the understanding of different types of variational behavior. A fundamental reliability model emerges from the correlation between the appropriate Q and H functions for performance requirement and achievement. This model may cover the complete spectrum of performance behavior in all the system dimensions

    Full Text Available Abstract Background Rating scales form an important means of gathering evaluation data. Since important decisions are often based on these evaluations, determining the reliability of rating data can be critical. Most commonly used methods of estimating reliability require a complete set of ratings i.e. every subject being rated must be rated by each judge. Over fifty years ago Ebel described an algorithm for estimating the reliability of ratings based on incomplete data. While his article has been widely cited over the years, software based on the algorithm is not readily available. This paper describes an easy-to-use Web-based utility for estimating the reliability of ratings based on incomplete data using Ebel's algorithm. Methods The program is available public use on our server and the source code is freely available under GNU General Public License. The utility is written in PHP, a common open source imbedded scripting language. The rating data can be entered in a convenient format on the user's personal computer that the program will upload to the server for calculating the reliability and other statistics describing the ratings. Results When the program is run it displays the reliability, number of subject rated, harmonic mean number of judges rating each subject, the mean and standard deviation of the averaged ratings per subject. The program also displays the mean, standard deviation and number of ratings for each subject rated. Additionally the program will estimate the reliability of an average of a number of ratings for each subject via the Spearman-Brown prophecy formula. Conclusion This simple web-based program provides a convenient means of estimating the reliability of rating data without the need to conduct special studies in order to provide complete rating data. I would welcome other researchers revising and enhancing the program.

    For an exact evaluation of the reliability of a structure it appears necessary to determine the distribution densities of the loads and resistances and to calculate the correlation coefficients between loads and between resistances. These statistical characteristics can be obtained only on the basis of a long activity period. In case that such studies are missing the statistical properties formulated here give upper and lower bounds of the reliability. (orig./HP) [de

    The objective of this study is to develop a new methodology for estimating the reliability of engineering systems that encompass multiple disciplines. The methodology is formulated in the context of the NESSUS probabilistic structural analysis code, developed under the leadership of NASA Glenn Research Center. The NESSUS code has been successfully applied to the reliability estimation of a variety of structural engineering systems. This study examines whether the features of NESSUS could be used to investigate the reliability of systems in other disciplines such as heat transfer, fluid mechanics, electrical circuits etc., without considerable programming effort specific to each discipline. In this study, the mechanical equivalence between system behavior models in different disciplines are investigated to achieve this objective. A new methodology is presented for the analysis of heat transfer, fluid flow, and electrical circuit problems using the structural analysis routines within NESSUS, by utilizing the equivalence between the computational quantities in different disciplines. This technique is integrated with the fast probability integration and system reliability techniques within the NESSUS code, to successfully compute the system reliability of multidisciplinary systems. Traditional as well as progressive failure analysis methods for system reliability estimation are demonstrated, through a numerical example of a heat exchanger system involving failure modes in structural, heat transfer and fluid flow disciplines.

    2017-05-01

    SL-AV (semi-Lagrangian, based on the absolute vorticity equation) is a global hydrostatic atmospheric model. Its latest version, SL-AV20, provides global operational medium-range weather forecast with 20 km resolution over Russia. The lower-resolution configurations of SL-AV20 are being tested for seasonal prediction and climate modeling. The article presents the model dynamical core. Its main features are a vorticity-divergence formulation at the unstaggered grid, high-order finite-difference approximations, semi-Lagrangian semi-implicit discretization and the reduced latitude-longitude grid with variable resolution in latitude. The accuracy of SL-AV20 numerical solutions using a reduced lat-lon grid and the variable resolution in latitude is tested with two idealized test cases. Accuracy and stability of SL-AV20 in the presence of the orography forcing are tested using the mountain-induced Rossby wave test case. The results of all three tests are in good agreement with other published model solutions. It is shown that the use of the reduced grid does not significantly affect the accuracy up to the 25 % reduction in the number of grid points with respect to the regular grid. Variable resolution in latitude allows us to improve the accuracy of a solution in the region of interest.

  6. sugE: A gene involved in tributyltin (TBT) resistance of Aeromonas molluscorum Av27.

    The mechanism of bacterial resistance to tributyltin (TBT) is still unclear. The results herein presented contribute to clarify that mechanism in the TBT-resistant bacterium Aeromonas molluscorum Av27. We have identified and cloned a new gene that is involved in TBT resistance in this strain. The gene is highly homologous (84%) to the Aeromonas hydrophila-sugE gene belonging to the small multidrug resistance gene family (SMR), which includes genes involved in the transport of lipophilic drugs. In Av27, expression of the Av27-sugE was observed at the early logarithmic growth phase in the presence of a high TBT concentration (500 μM), thus suggesting the contribution of this gene for TBT resistance. E. coli cells transformed with Av27-sugE become resistant to ethidium bromide (EtBr), chloramphenicol (CP) and tetracycline (TE), besides TBT. According to the Moriguchi logP (miLogP) values, EtBr, CP and TE have similar properties and are substrates for the sugE-efflux system. Despite the different miLogP of TBT, E. coli cells transformed with Av27-sugE become resistant to this compound. So it seems that TBT is also a substrate for the SugE protein. The modelling studies performed also support this hypothesis. The data herein presented clearly indicate that sugE is involved in TBT resistance of this bacterium.

    Energy-derived waters containing naphthenic acids (NAs) are complex mixtures often comprising a suite of potentially problematic constituents (e.g. organics, metals, and metalloids) that need treatment prior to beneficial use, including release to receiving aquatic systems. It has previously been suggested that NAs can have biostatic or biocidal properties that could inhibit microbially driven processes (e.g. dissimilatory sulfate reduction) used to transfer or transform metals in passive treatment systems (i.e. constructed wetlands). The overall objective of this study was to measure the effects of a commercially available (Fluka) NA on sulfate-reducing bacteria (SRB), production of sulfides (as acid-volatile sulfides [AVS]), and precipitation of divalent metals (i.e. Cu, Ni, Zn). These endpoints were assessed following 21-d aqueous exposures of NAs using bench-scale reactors. After 21-days, AVS molar concentrations were not statistically different (pAVS production was sufficient in all NA treatments to achieve ∑SEM:AVS AVS) could be used to treat metals occurring in NAs affected waters.

Validity was assessed by comparing measurements simultaneously obtained using the Tendo Weightlifting Analyzer Systemi and T-Force Dynamic Measurement Systemr (Ergotech, Murcia, Spain during two resistance exercises, bench press (BP and full back squat (BS, performed by 71 trained male subjects. For the reliability study, a further 32 men completed both lifts using the Tendo Weightlifting Analyzer Systemz in two identical testing sessions one week apart (session 1 vs. session 2. Intraclass correlation coefficients (ICCs indicating the validity of the Tendo Weightlifting Analyzer Systemi were high, with values ranging from 0.853 to 0.989. Systematic biases and random errors were low to moderate for almost all variables, being higher in the case of PP (bias ±157.56 W; error ±131.84 W. Proportional biases were identified for almost all variables. Test-retest reliability was strong with ICCs ranging from 0.922 to 0.988. Reliability results also showed minimal systematic biases and random errors, which were only significant for PP (bias -19.19 W; error ±67.57 W. Only PV recorded in the BS showed no significant proportional bias. The Tendo Weightlifting Analyzer Systemi emerged as a reliable system for measuring movement velocity and estimating power in resistance exercises. The low biases and random errors observed here (mainly AV, AP make this device a useful tool for monitoring resistance training.

    Permanent AV-block is a recognized and feared complication of slow pathway modulation for AVNRT. We aimed to assess incidence of transient and permanent AV-block as well as consequences of transient AV-block in a large contemporary AVNRT ablation cohort. We searched our single center prospective ablation database for occurrence of transient and permanent AV-block during slow pathway modulation between January 2004 and October 2015. We analyzed patients' and procedural characteristics as well as outcome of patients in whom transient or permanent AV-block occurred. Of 9170 patients who underwent a catheter ablation at our institution between January 2004 and October 2015, 2101 patients (64% women, mean age 50±18years) underwent slow pathway modulation. In three patients, permanent AV-block occurred during RF application. Additional two patients had transient AV-block that recovered (after a few minutes and 25min), but recurred within two days of the procedure. All five patients underwent dual chamber pacemaker implantation (0.2%). Transient AV-block related to RF delivery occurred in 44 patients (2%). Transient mechanical AV-block occurred in additional 17 patients (0.8%). In 12 patients, ablation was continued despite transient AV-block. One of these patients developed permanent AV-block. Permanent AV-block following slow pathway modulation is a rare event, occurring in 0.2% of patients in a large contemporary single center cohort. Transient AV-block is more frequent (2%).

Los registros internacionales de mutaciones refieren una elevada frecuencia (65-70% de deleciones/duplicaciones de uno o más exones del gen DYS. En este trabajo presentamos el estudio de alteraciones numéricas en los 79 exones del gen DYS. El estudio fue realizado en 59 individuos pertenecientes a 31 familias no relacionadas. La metodología utilizada fue Multiplex Ligation Dependent Probe Amplification (MLPA. En los 31 casos independientes se estableció además el score clínico, se realizó el test de Raven y se determinaron los valores de creatininfosfoquinasa (CPK en sangre. Nuestros datos revelan una frecuencia de alteraciones numéricas en el gen DYS del 61.3%, provocando un corrimiento del marco de lectura en el 100% de los casos. Se observó una región con mayor tendencia a presentar alteraciones que involucran un solo exón. La tasa de mutación de novo identificada fue del 35.2%. Se halló, a su vez, una asociación significativa entre afectados con alteraciones numéricas y valores del test de Raven de bajo rendimiento. Estos resultados aportan datos a los conocimientos regionales sobre las alteraciones genéticas y su impacto fenotípico en la enfermedad de Duchenne/Becker.

    Combustible products from fragmentation are not allowed to be deposited on landfills any more in Sweden. These products have to be material recovered or energy recovered. The combustible fraction from recovered metal scrap, SLF (shredder light fraction), contains metals and the chlorine content is relatively high. Due to this there could be a risk with deposits and corrosion on convection surfaces in combustion plants. Co-combustion with sewage sludge could be a solution for solving problems with the difficult contents in SLF. The aim of the project was to do a theoretical judgment of how sewage sludge could affect deposit formation and corrosion when co-combusted with SLF. Due to the high amount of water in the sewage sludge the percentage of sewage sludge in the fuel mixture was limited. The maximum percentage of energy used was 3.5 % (ca 13% on weight basis). The thermodynamic calculations showed that at combustion with 100% SLF the lead and zinc chlorides in gaseous form increased 5-6 times in comparative with combustion with ordinary waste combustion in Boraas. But as the thermodynamic equilibrium calculations will not consider the kinetics and just calculate independent of time the results should be considered as indicative and not directly comparative to actual boiler conditions. All lead and zinc were assumed reactive which will probably not be the case in a boiler. In the calculations the aluminum was removed from the calculations (not taken into account) and the alkali-phosphor reactions are incomplete due to lack of reliable thermodynamic data. These defiance's should be considered when evaluating the results from the thermodynamic chemical equilibrium calculations as well as the fact that the calculations cannot yet take into account the possible erosive effect the high ash amount could have on the deposits. The calculations showed that co-combusting with SLF (ca 20%) gave high amounts of gaseous lead chlorides. Also high amount of zinc chlorides

    Full Text Available Denne artikkelen er skrevet ut fra en antakelse om at norsk utdanningsforvaltning etter 1990 illustrerer forsøk på å styrke den statlige forvaltning innen et desentralisert system.

  1. Safety and reliability criteria

    International Nuclear Information System (INIS)

    O'Neil, R.

    1978-01-01

    Nuclear power plants and, in particular, reactor pressure boundary components have unique reliability requirements, in that usually no significant redundancy is possible, and a single failure can give rise to possible widespread core damage and fission product release. Reliability may be required for availability or safety reasons, but in the case of the pressure boundary and certain other systems safety may dominate. Possible Safety and Reliability (S and R) criteria are proposed which would produce acceptable reactor design. Without some S and R requirement the designer has no way of knowing how far he must go in analysing his system or component, or whether his proposed solution is likely to gain acceptance. The paper shows how reliability targets for given components and systems can be individually considered against the derived S and R criteria at the design and construction stage. Since in the case of nuclear pressure boundary components there is often very little direct experience on which to base reliability studies, relevant non-nuclear experience is examined. (author)

  2. Proposed reliability cost model

    Science.gov (United States)

    Delionback, L. M.

    1973-01-01

    The research investigations which were involved in the study include: cost analysis/allocation, reliability and product assurance, forecasting methodology, systems analysis, and model-building. This is a classic example of an interdisciplinary problem, since the model-building requirements include the need for understanding and communication between technical disciplines on one hand, and the financial/accounting skill categories on the other. The systems approach is utilized within this context to establish a clearer and more objective relationship between reliability assurance and the subcategories (or subelements) that provide, or reenforce, the reliability assurance for a system. Subcategories are further subdivided as illustrated by a tree diagram. The reliability assurance elements can be seen to be potential alternative strategies, or approaches, depending on the specific goals/objectives of the trade studies. The scope was limited to the establishment of a proposed reliability cost-model format. The model format/approach is dependent upon the use of a series of subsystem-oriented CER's and sometimes possible CTR's, in devising a suitable cost-effective policy.

    Full Text Available En quelques années, l’arrivée d’Internet et le développement des nouvelles technologies ont profondément transformé le paysage des bibliothèques de l’enseignement supérieur en France, comme ailleurs. Constitué de 96 bibliothèques universitaires et de six bibliothèques de grands établissements, ce vaste réseau documentaire s’est enrichi d’une offre numérique de qualité qu’elle met à disposition d’un public sans cesse élargi. Poursuivant leurs missions traditionnelles d’acquisition, de signalement et de diffusion de l’information, ces bibliothèques ont depuis longtemps pris conscience des potentialités offertes par le format numérique pour diffuser à distance une offre documentaire enrichie: acquisition de documents nativement numériques, numérisation de collections matérielles au sein même des établissements, voire édition électronique de documents créés dans le cadre de l’Université. La maîtrise de ces nouvelles technologies, alliée à un savoirfaire professionnel acquis au fil du temps, entraîne ainsi une évolution du rôle de médiateur de la bibliothèque qui se double à présent d’un rôle émergent de producteur de l’information scientifique et technique. Les bibliothèques de l’enseignement supérieur, en France, s’inscrivent très précisément dans ce contexte où les frontières traditionnelles entre la production, l’édition, le traitement et la diffusion de l’information sont d’ores et déjà abolies.

  1. The parsec-scale relationship between ICO and AV in local molecular clouds

    Science.gov (United States)

    Lee, Cheoljong; Leroy, Adam K.; Bolatto, Alberto D.; Glover, Simon C. O.; Indebetouw, Remy; Sandstrom, Karin; Schruba, Andreas

    2018-03-01

    We measure the parsec-scale relationship between integrated CO intensity (ICO) and visual extinction (AV) in 24 local molecular clouds using maps of CO emission and dust optical depth from Planck. This relationship informs our understanding of CO emission across environments, but clean Milky Way measurements remain scarce. We find uniform ICO for a given AV, with the results bracketed by previous studies of the Pipe and Perseus clouds. Our measured ICO-AV relation broadly agrees with the standard Galactic CO-to-H2 conversion factor, the relation found for the Magellanic clouds at coarser resolution, and numerical simulations by Glover & Clark (2016). This supports the idea that CO emission primarily depends on shielding, which protects molecules from dissociating radiation. Evidence for CO saturation at high AV and a threshold for CO emission at low AV varies remains uncertain due to insufficient resolution and ambiguities in background subtraction. Resolution of order 0.1 pc may be required to measure these features. We use this ICO-AV relation to predict how the CO-to-H2 conversion factor (XCO) would change if the Solar Neighbourhood clouds had different dust-to-gas ratio (metallicity). The calculations highlight the need for improved observations of the CO emission threshold and H I shielding layer depth. They are also sensitive to the shape of the column density distribution. Because local clouds collectively show a self-similar distribution, we predict a shallow metallicity dependence for XCO down to a few tenths of solar metallicity. However, our calculations also imply dramatic variations in cloud-to-cloud XCO at subsolar metallicity.

  2. Reliability Centered Maintenance - Methodologies

    Kammerer, Catherine C.

    2009-01-01

    Journal article about Reliability Centered Maintenance (RCM) methodologies used by United Space Alliance, LLC (USA) in support of the Space Shuttle Program at Kennedy Space Center. The USA Reliability Centered Maintenance program differs from traditional RCM programs because various methodologies are utilized to take advantage of their respective strengths for each application. Based on operational experience, USA has customized the traditional RCM methodology into a streamlined lean logic path and has implemented the use of statistical tools to drive the process. USA RCM has integrated many of the L6S tools into both RCM methodologies. The tools utilized in the Measure, Analyze, and Improve phases of a Lean Six Sigma project lend themselves to application in the RCM process. All USA RCM methodologies meet the requirements defined in SAE JA 1011, Evaluation Criteria for Reliability-Centered Maintenance (RCM) Processes. The proposed article explores these methodologies.

  3. Issues in cognitive reliability

    International Nuclear Information System (INIS)

    Woods, D.D.; Hitchler, M.J.; Rumancik, J.A.

    1984-01-01

    This chapter examines some problems in current methods to assess reactor operator reliability at cognitive tasks and discusses new approaches to solve these problems. The two types of human failures are errors in the execution of an intention and errors in the formation/selection of an intention. Topics considered include the types of description, error correction, cognitive performance and response time, the speed-accuracy tradeoff function, function based task analysis, and cognitive task analysis. One problem of human reliability analysis (HRA) techniques in general is the question of what are the units of behavior whose reliability are to be determined. A second problem for HRA is that people often detect and correct their errors. The use of function based analysis, which maps the problem space for plant control, is recommended

  13. Betydningen av drektige reinsimlers ernæring for kalvers vekst, klimatiske toleranse og overlevelse

    Directory of Open Access Journals (Sweden)

    Arne Rognmo

    2013-03-01

    Full Text Available Forsøkene (viste at tilleggsforing av underernærte simler i siste del av drektighetsperioden kun synes å ha effekt på fødselsvekten for kalvene forutsatt at simlene får høyverdig ernæring etter kalving. Den forskjellige ernæringsbakgrunn før kalving synes således ikke å innvirke på melkeproduksjon/kvalitet, da vektutviklingen for alle grupper av kalver i dette forsøket gikk parallelt i de tre første ukene etter kalving. Det ble heller ikke på noe punkt funnet signifikante forskjeller gruppene imellom når det gjelder kalvenes klimatiske toleranse. Det er dog bemerkelsesverdig at det var stor dødelighet blant de små kalvene etter unge små simler i GRUPPE L. Dette funn er interessant sett i sammenheng med resultatene fra Røros (se bidrag fra Dag Lenvik, side som viser at avkastningen fra en flokk kan økes markant om man konsentrerte slakteuttaket på små kalver og forhindrer bedekning av små, unge simler gjennom fjerning av eldre, store bukker. Med det forbehold at våre forsøk er utført på dyr i innhegning med et lavt aktivitetsnivå, kan man fra våreforsøk foreløpig konkludere med at tillegsfor ing av simler i siste halvdel av drektighetsperioden har effekt på kalvenes fødselsvekt, men at vektutviklingen for kalven er uavhengig av simlenes ernæringshistorie, om sistnevnte tilbys høyverdig ernæring etter kalving. Da små kalver etter underernærte simler viste høy dødelighet like etter fødselen, vil imidlertid tilleggsforing kunne øke avkastningen om det er mange unge simler i flokken. Resultatene fra Røros tyder imidlertid på at dette resultat normalt kan oppnås uten ekstra omkostninger gjennom et selektivt slakteuttak.

    Full Text Available Teoretisk og praktisk kunnskap fungerer etter ulik logikk, ingen teori kan helt omsettes til praksis. Det er derfor av interesse å undersøke nærmere hvordan nyutdannede lærere opplever både sin fagkunnskap og nyervervede kompetanse i yrket. Undersøkelsen som her blir presentert har følgende problemstilling: Hvordan opplever nyutdannede lærere sin kompetanse i leseopplæring generelt og leseopplæring av elever med lesevansker spesielt? Denne pilotundersøkelsen tar utgangspunkt i Q- metoden; nyutdannede lærere plasserer subjektive utsagn trykt på individuelle kort i en matrise. Pilotundersøkelsen baserer seg på 10 respondenter, vi valgte derfor en kvalitativ analyse av resultatene av Q-sorteringen. Resultatene viser at nyutdannede lærere opplever at de mangler kunnskap og kompetanse både i praktisk leseopplæring generelt og om lesevansker spesielt. Kartleggingsmateriell blir i liten grad brukt som grunnlag for informantenes tilrettelegging av arbeidsmåter i leseopplæring. Inkludering og sammenholdte klasser står sterkt hos informantene, men de savner informasjon om elever med lesevansker og om tilgjengelig hjelpemateriell.

    2010-01-01

    Energieffektivisering i bygninger regnes som et av de mest kostnadseffektive tiltakene for å redusere forbruk av energi, samt bidra til reduksjon i klimagassutslipp. I følge rapporter fra blant annet Lavenergiutvalget (2009) og Klimakur 2020 (2010), vil det være mulig å frigjøre rundt 10 TWh elektrisitet fra norske bygninger i løpet av de neste ti årene. Denne masteroppgaven tar for seg følgene av en tilsvarende etterspørselsreduksjon i det norske kraftsystemet. Norge har et kraftsystem med n...

    1991-07-01

    Reliability is an increasing concern when moving PACS from the experimental laboratory to the clinical environment. Any system downtime may seriously affect patient care. The authors report on the several classes of errors encountered during the pre-clinical release of the PACS during the past several months and present the solutions implemented to handle them. The reliability issues discussed include: (1) environmental precautions, (2) database backups, (3) monitor routines of critical resources and processes, (4) hardware redundancy (networks, archives), and (5) development of a PACS quality control program.

    1983-01-01

    In order to obtain public understanding on nuclear power plants, tests should be carried out to prove the reliability and safety of present LWR plants. For example, the aseismicity of nuclear power plants must be verified by using a large scale earthquake simulator. Reliability test began in fiscal 1975, and the proof tests on steam generators and on PWR support and flexure pins against stress corrosion cracking have already been completed, and the results have been internationally highly appreciated. The capacity factor of the nuclear power plant operation in Japan rose to 80% in the summer of 1983, and considering the period of regular inspection, it means the operation of almost full capacity. Japanese LWR technology has now risen to the top place in the world after having overcome the defects. The significance of the reliability test is to secure the functioning till the age limit is reached, to confirm the correct forecast of deteriorating process, to confirm the effectiveness of the remedy to defects and to confirm the accuracy of predicting the behavior of facilities. The reliability of nuclear valves, fuel assemblies, the heat affected zones in welding, reactor cooling pumps and electric instruments has been tested or is being tested. (Kako, I.)

  11. Parametric Mass Reliability Study

    Science.gov (United States)

    Holt, James P.

    2014-01-01

    The International Space Station (ISS) systems are designed based upon having redundant systems with replaceable orbital replacement units (ORUs). These ORUs are designed to be swapped out fairly quickly, but some are very large, and some are made up of many components. When an ORU fails, it is replaced on orbit with a spare; the failed unit is sometimes returned to Earth to be serviced and re-launched. Such a system is not feasible for a 500+ day long-duration mission beyond low Earth orbit. The components that make up these ORUs have mixed reliabilities. Components that make up the most mass-such as computer housings, pump casings, and the silicon board of PCBs-typically are the most reliable. Meanwhile components that tend to fail the earliest-such as seals or gaskets-typically have a small mass. To better understand the problem, my project is to create a parametric model that relates both the mass of ORUs to reliability, as well as the mass of ORU subcomponents to reliability.

  14. Diphenylhydantoin and lidocaine modification of A-V conduction in halothane-anesthetized dogs.

    Science.gov (United States)

    Atlee, J L; Homer, L D; Tobey, R E

    1975-07-01

    The effect of halothane on A-V conduction was evaluated in gods during atrial pacing using the technique of His-bundle electrocardiography. In addition, the effects of lidocaine and diphenylkydantoin (DPH) on A-V conuction were examined during halothane anesthesia. Effects of these drugs on three subintervals of A-V conduction were compared. These included the -H (stimulus atifact of His-bundle deflection-atrioventricular conduction), H-Q (His-budnle deflection onset of QRS complex-His-Purkinje conduction), and H-S intervals(His-bundle delfection to end of QRS COmplex-total intraventricular conduction). Linear regression best described the relationship between duration of interval (P-H, H-V,and H-S) and heart rate during incremental increases in the atrial paced rate. Data from these experiments were fitted to a multiple lenear regression model that predicted the effect of increasing concentrations of halothan, lidocaine, and DPH on slope and intercept coefficients. In creasing concentrations of halothan ( 30 and 45 mg/100 ml arterial). Both lidocaine and DPH further depressed conduction at all levels of halothan anesthesia. The P-H interval was particularly sensitive todrug effefts. This may represent potentiation of the normal slowing of conduction through the AVnode in response to incremental increases in heart rate (fatigue response.) We conclude thatboth lidocaine and DPH fail to reverse the depressant effect of halothane on A-V conduction. This may explain their ineffectiveness in treating certain types of arrhythmias during halothane anesthesia.

    In risk assessment of aquatic sediments, much attention is paid to the difference between acid-volatile sulfide (AVS) and simultaneously extracted metals (SEMs) as indicators of metal availability. Ten representative sampling sites were selected along the estuary of the Guadalete River. Surficial sediments were sampled in winter and summer to better understand SEM and AVS spatial and seasonal distributions and to establish priority risk areas. Total SEM concentration (SigmaSEM) ranged from 0.3 to 4.7 micromol g(-1). It was not significantly different between seasons, however, it showed a significant difference between sampling stations. AVS concentrations were much more variable, showing significant spatial and temporal variations. The values ranged from 0.8 to 22.4 micromol g(-1). The SEM/AVS ratio was found to be <1 at all except one station located near the mouth of the estuary. The results provided information on a potential pollution source near the mouth of the estuary, probably associated with vessel-related activities carried out in a local harbor area located near the station.

    Retinoic acid receptor-related orphan receptor-α (RORα) (NR1F1) is an orphan nuclear receptor with a potential role in metabolism. Previous studies have shown that RORα regulates transcription of the murine Apolipoprotein AI gene and human Apolipoprotein CIII genes. In the present study, we present evidence that RORα also induces transcription of the human Apolipoprotein AV gene, a recently identified apolipoprotein associated with triglyceride levels. Adenovirus-mediated overexpression of RORα increased the endogenous expression of ApoAV in HepG2 cells and RORα also enhanced the activity of an ApoAV promoter construct in transiently transfected HepG2 cells. Deletion and mutation studies identified three AGGTCA motifs in the ApoAV promoter that mediate RORα transactivation, one of which overlaps with a previously identified binding site for PPARα. Together, these results suggest a novel mechanism whereby RORα modulates lipid metabolism and implies RORα as a potential target for the treatment of dyslipidemia and atherosclerosis

  4. RTE - Reliability report 2016

    International Nuclear Information System (INIS)

    2017-06-01

    Every year, RTE produces a reliability report for the past year. This document lays out the main factors that affected the electrical power system's operational reliability in 2016 and the initiatives currently under way intended to ensure its reliability in the future. Within a context of the energy transition, changes to the European interconnected network mean that RTE has to adapt on an on-going basis. These changes include the increase in the share of renewables injecting an intermittent power supply into networks, resulting in a need for flexibility, and a diversification in the numbers of stakeholders operating in the energy sector and changes in the ways in which they behave. These changes are dramatically changing the structure of the power system of tomorrow and the way in which it will operate - particularly the way in which voltage and frequency are controlled, as well as the distribution of flows, the power system's stability, the level of reserves needed to ensure supply-demand balance, network studies, assets' operating and control rules, the tools used and the expertise of operators. The results obtained in 2016 are evidence of a globally satisfactory level of reliability for RTE's operations in somewhat demanding circumstances: more complex supply-demand balance management, cross-border schedules at interconnections indicating operation that is closer to its limits and - most noteworthy - having to manage a cold spell just as several nuclear power plants had been shut down. In a drive to keep pace with the changes expected to occur in these circumstances, RTE implemented numerous initiatives to ensure high levels of reliability: - maintaining investment levels of euro 1.5 billion per year; - increasing cross-zonal capacity at borders with our neighbouring countries, thus bolstering the security of our electricity supply; - implementing new mechanisms (demand response, capacity mechanism, interruptibility, etc.); - involvement in tests or projects

    As part of the Dawn's orbital mapping investigation of Vesta, the Science Team is conducting geologic mapping of the surface in the form of 15 quadrangle maps, including quadrangle Av-11 (Pinaria). The base map is a monochrome Framing Camera (FC) mosaic at ~70 m/pixel, supplemented by Digital Terrain Models (DTM) and FC color ratio images, both at ~250 m/pixel, slope and contour maps, and Visible and Infrared (VIR) hyperspectral images. Av-11 straddles the 45-degree longitude in the South Polar Region, and is dominated by the rim of the ~505 km south polar topographic feature, Rheasilvia. Sparsely cratered (relatively), Av-11 is dominated by a 20 km high rim scarp (Matronalia Rupes) and by arcuate ridges and troughs forming a radial to spiral pattern across the basin floor. Primary geologic features of Av-11 include the following. Ridge-and-groove terrain radiating arcuately from the central mound unit, interpreted to be structural disruption of the basin floor associated with basin formation. The largest crater in Av-11 is Pinaria (37 km). Mass wasting deposits are observed on its floor. Secondary crater chains and fields are also evident. Mass wasting observed along Rheasilvia rim scarp and in the largest craters indicates scarp failure is a significant process. Parallel fault scarps mark this deposit of slumped debris at the base of 20 km high Matronalia Rupes, which may have formed during or shortly after basin excavation. We interpret most of these deposits as slump material emplaced as a result of the effects of basin formation and collapse. Lobate materials are characterized by lineations and lobate scarps and interpreted as Rheasilvia ejecta deposit outside Rheasilvia rim (the smoothest terrain on Vesta), and are consistent with formation by ejecta. Partial burial of older craters near the edge of these deposits are also observed.

    Acute excessive alcohol consumption is associated with heart rhythm disorders like atrial fibrillation but also premature ventricular contractions, collectively known as the "holiday heart syndrome". More rarely but clinically significant are reports of atrioventricular (AV) conduction disturbances in binge drinkers with no underlying heart disease or chronic alcohol consumption. To obtain better insights into common denominators and the potential underlying mechanisms we collected and compared individual case reports of AV block following acute alcohol intoxication in otherwise healthy people. By screening PubMed, Google Scholar, Scopus and JSTOR, fifteen cases were found of which eight were sufficiently documented for full analysis. Blood alcohol levels ranged from 90 to 958 mg/dl (19 to 205 mM). Second and third degree AV block was observed most (6/8) albeit that in two of these patients a vagal stimulus led to deterioration from first into higher order AV block. In all cases, patients reverted to normal sinus rhythm upon becoming sober again. Mildly lowered body temperature (35.9 ± 0.5°C) was observed but can be excluded as a major cause of conduction blockade. We hypothesize that ethanol induced partial inhibition of calcium and potentially also sodium currents in conductive tissue structures may be one of the mechanisms of conduction slowing and block that may become exaggerated upon increased vagal tone. An impairment of gap junction function cannot be excluded as a contributing factor. In conclusion, cases of documented alcohol induced AV block are very rare but events can occur at relatively low serum alcohol levels which should prompt to awareness of this phenomenon in alcohol intoxicated patients.

    Defensins are frontline peptides of mucosal immunity in the animal kingdom, including birds. Their resistance to proteolysis and their ensuing ability to maintain antimicrobial potential remains questionable and was therefore investigated. We have shown by bottom-up mass spectrometry analysis of protein extracts that both avian beta-defensins AvBD2 and AvBD7 were ubiquitously distributed along the chicken gut. Cathepsin B was found by immunoblotting in jejunum, ileum, caecum, and caecal tonsils, while cathepsins K, L, and S were merely identified in caecal tonsils. Hydrolysis product of AvBD2 and AvBD7 incubated with a panel of proteases was analysed by RP-HPLC, mass spectrometry and antimicrobial assays. AvBD2 and AvBD7 were resistant to serine proteases and to cathepsins D and H. Conversely cysteine cathepsins B, K, L, and S degraded AvBD2 and abolished its antibacterial activity. Only cathepsin K cleaved AvBD7 and released Ile4-AvBD7, a N-terminal truncated natural peptidoform of AvBD7 that displayed antibacterial activity. Besides the 3-stranded antiparallel beta-sheet typical of beta-defensins, structural analysis of AvBD7 by two-dimensional NMR spectroscopy highlighted the restricted accessibility of the C-terminus embedded by the N-terminal region and gave a formal evidence of a salt bridge (Asp9-Arg12) that could account for proteolysis resistance. The differential susceptibility of avian defensins to proteolysis opens intriguing questions about a distinctive role in the mucosal immunity against pathogen invasion.

    Proof of future performance of a complex system such as a high-level nuclear waste package over a period of hundreds to thousands of years cannot be had in the ordinary sense of the word. The general method of probabilistic reliability analysis could provide an acceptable framework to identify, organize, and convey the information necessary to satisfy the criterion of reasonable assurance of waste package performance according to the regulatory requirements set forth in 10 CFR 60. General principles which may be used to evaluate the qualitative and quantitative reliability of a waste package design are indicated and illustrated with a sample calculation of a repository concept in basalt. 8 references, 1 table

    2014-05-18

    A Human Reliability Program (HRP) is designed to protect national security as well as worker and public safety by continuously evaluating the reliability of those who have access to sensitive materials, facilities, and programs. Some elements of a site HRP include systematic (1) supervisory reviews, (2) medical and psychological assessments, (3) management evaluations, (4) personnel security reviews, and (4) training of HRP staff and critical positions. Over the years of implementing an HRP, the Department of Energy (DOE) has faced various challenges and overcome obstacles. During this 4-day activity, participants will examine programs that mitigate threats to nuclear security and the insider threat to include HRP, Nuclear Security Culture (NSC) Enhancement, and Employee Assistance Programs. The focus will be to develop an understanding of the need for a systematic HRP and to discuss challenges and best practices associated with mitigating the insider threat.

    Full Text Available The goal of this study was to determine the most reliable and efficient combination of design and construction methods required for vibro piles. For a wide range of static and dynamic formulas, the reliability-based resistance factors were calculated using EGYPT database, which houses load test results for 318 piles. The analysis was extended to introduce a construction control factor that determines the variation between the pile nominal capacities calculated using static versus dynamic formulae. From the major outcomes, the lowest coefficient of variation is associated with Davisson’s criterion, and the resistance factors calculated for the AASHTO method are relatively high compared with other methods. Additionally, the CPT-Nottingham and Schmertmann method provided the most economic design. Recommendations related to a pile construction control factor were also presented, and it was found that utilizing the factor can significantly reduce variations between calculated and actual capacities.

  14. Scyllac equipment reliability analysis

    Most of the failures in Scyllac can be related to crowbar trigger cable faults. A new cable has been designed, procured, and is currently undergoing evaluation. When the new cable has been proven, it will be worked into the system as quickly as possible without causing too much additional down time. The cable-tip problem may not be easy or even desirable to solve. A tightly fastened permanent connection that maximizes contact area would be more reliable than the plug-in type of connection in use now, but it would make system changes and repairs much more difficult. The balance of the failures have such a low occurrence rate that they do not cause much down time and no major effort is underway to eliminate them. Even though Scyllac was built as an experimental system and has many thousands of components, its reliability is very good. Because of this the experiment has been able to progress at a reasonable pace

    Full Text Available We present a confirmatory factor analysis (CFA procedure for computing the reliability of circumplex axes. The tau-equivalent CFA variance decomposition model estimates five variance components: general factor, axes, scale-specificity, block-specificity, and item-specificity. Only the axes variance component is used for reliability estimation. We apply the model to six circumplex types and 13 instruments assessing interpersonal and motivational constructs—Interpersonal Adjective List (IAL, Interpersonal Adjective Scales (revised; IAS-R, Inventory of Interpersonal Problems (IIP, Impact Messages Inventory (IMI, Circumplex Scales of Interpersonal Values (CSIV, Support Action Scale Circumplex (SAS-C, Interaction Problems With Animals (IPI-A, Team Role Circle (TRC, Competing Values Leadership Instrument (CV-LI, Love Styles, Organizational Culture Assessment Instrument (OCAI, Customer Orientation Circle (COC, and System for Multi-Level Observation of Groups (behavioral adjectives; SYMLOG—in 17 German-speaking samples (29 subsamples, grouped by self-report, other report, and metaperception assessments. The general factor accounted for a proportion ranging from 1% to 48% of the item variance, the axes component for 2% to 30%; and scale specificity for 1% to 28%, respectively. Reliability estimates varied considerably from .13 to .92. An application of the Nunnally and Bernstein formula proposed by Markey, Markey, and Tinsley overestimated axes reliabilities in cases of large-scale specificities but otherwise works effectively. Contemporary circumplex evaluations such as Tracey’s RANDALL are sensitive to the ratio of the axes and scale-specificity components. In contrast, the proposed model isolates both components.

    1994-01-01

    There are many software reliability models which try to predict future performance of software based on data generated by the debugging process. Our research has shown that by improving the quality of the data one can greatly improve the predictions. We are working on methodologies which control some of the randomness inherent in the standard data generation processes in order to improve the accuracy of predictions. Our contribution is twofold in that we describe an experimental methodology using a data structure called the debugging graph and apply this methodology to assess the robustness of existing models. The debugging graph is used to analyze the effects of various fault recovery orders on the predictive accuracy of several well-known software reliability algorithms. We found that, along a particular debugging path in the graph, the predictive performance of different models can vary greatly. Similarly, just because a model 'fits' a given path's data well does not guarantee that the model would perform well on a different path. Further we observed bug interactions and noted their potential effects on the predictive process. We saw that not only do different faults fail at different rates, but that those rates can be affected by the particular debugging stage at which the rates are evaluated. Based on our experiment, we conjecture that the accuracy of a reliability prediction is affected by the fault recovery order as well as by fault interaction.

  1. Investment in new product reliability

    International Nuclear Information System (INIS)

    Murthy, D.N.P.; Rausand, M.; Virtanen, S.

    2009-01-01

    Product reliability is of great importance to both manufacturers and customers. Building reliability into a new product is costly, but the consequences of inadequate product reliability can be costlier. This implies that manufacturers need to decide on the optimal investment in new product reliability by achieving a suitable trade-off between the two costs. This paper develops a framework and proposes an approach to help manufacturers decide on the investment in new product reliability.

    Av3, a neurotoxin of Anemonia viridis, is toxic to crustaceans and cockroaches but inactive in mammals. In the present study, Av3 was expressed in Escherichia coli Origami B (DE3) and purified by reversed-phase liquid chromatography. The purified Av3 was injected into the hemocoel of Helicoverpa armigera, rendering the worm paralyzed. Then, Av3 was expressed alone or fusion expressed with the Cry1Ac in acrystalliferous strain Cry(-)B of Bacillus thuringiensis. The shape of Cry1Ac was changed by fusion with Av3. The expressed fusion protein, Cry1AcAv3, formed irregular rhombus- or crescent-shaped crystalline inclusions, which is quite different from the shape of original Cry1Ac crystals. The toxicity of Cry1Ac was improved by fused expression. Compared with original Cry1Ac expressed in Cry(-)B, the oral toxicity of Cry1AcAv3 to H. armigera was elevated about 2.6-fold. No toxicity was detected when Av3 was expressed in Cry(-)B alone. The present study confirmed that marine toxins could be used in bio-control and implied that fused expression with other insecticidal proteins could be an efficient way for their application.

    1993-01-01

    If fewer forced outages are a sign of improved safety, nuclear power plants have become safer and more productive. There has been a significant improvement in nuclear power plant performance, due largely to a decline in the forced outage rate and a dramatic drop in the average number of forced outages per fuel cycle. If fewer forced outages are a sign of improved safety, nuclear power plants have become safer and more productive over time. To encourage further increases in performance, regulatory incentive schemes should reward reactor operators for improved reliability and safety, as well as for improved performance

    2016-02-17

    Neuronavigation plays a central role in modern neurosurgery. It allows visualizing instruments and three-dimensional image data intraoperatively and supports spatial orientation. Thus it allows to reduce surgical risks and speed up complex surgical procedures. The growing availability and importance of neuronavigation makes clear how relevant it is to know about its reliability and accuracy. Different factors may influence the accuracy during the surgery unnoticed, misleading the surgeon. Besides the best possible optimization of the systems themselves, a good knowledge about its weaknesses is mandatory for every neurosurgeon.

    We derive the value of reliability in the scheduling of an activity of random duration, such as travel under congested conditions. Using a simple formulation of scheduling utility, we show that the maximal expected utility is linear in the mean and standard deviation of trip duration, regardless...... of the form of the standardised distribution of trip durations. This insight provides a unification of the scheduling model and models that include the standard deviation of trip duration directly as an argument in the cost or utility function. The results generalise approximately to the case where the mean...

Esta pesquisa discorre sobre a construção de modelos numéricos em elementos finitos para investigar o efeito da utilização de componentes móveis (capô, portas laterais e tampa do porta malas na resposta acústica de um veículo. Para tanto, foram construídos dois modelos: um que abrange a utilização de todos os componentes móveis, e outro, que substitui cada componente móvel por elementos unidimensionais (1D, contendo apenas a massa e a inércia que representa cada um destes componentes. A resposta obtida em cada uma das etapas da simulação numérica é comparada com os resultados experimentais, a fim de validar o procedimento e compreender a significância da utilização de um modelo numérico simplificado e assim, validar um modelo simplificado capaz de reproduzir computacionalmente e de forma satisfatória a resposta acústica de um veículo. A utilização do referido modelo simplificado possibilita a indústria automotiva realizar estudos sobre a performance acústica de um veículo de forma antecipada, uma vez que não necessita esperar o desenvolvimento destes componentes. Como investigado nesta pesquisa, a influência de componentes móveis sobre a resposta acústica do modelo numérico completo é pequena quando comparado à resposta obtida pelo modelo simplificado.  Por meio de uma segunda análise, “Participação de Painéis”, é visto que a contribuição na resposta acústica final dos componentes móveis somados é inferior a 3dB.Palavras-chave: Método dos Elementos Finitos.

    Undersökningens syfte är att ta reda på hur JavaScript‐ramverk presterar i jämförelse med  ren JavaScript i en kommunikation med en webbservice. Kommunikationen med en  webbservice är tillståndslös. Detta innebär att en webbapplikations förfrågan mot en  webbservice alltid är en ny förfrågan. En webbservice kommer inte ihåg klientens tidigare  frågor.   Det finns idag en rad olika JavaScript‐ramverk som klarar av en kommunikation av sådan  karaktär. Denna undersökning kommer att utvärdera pre...

    The AV-reentrant tachycardia (AVRT) is a supraventricular tachycardia with an incidence of 1-3/1000. The pathophysiological basis is an accessory atrioventricular pathway (AP). Patients with AVRT typically present with palpitations, an on-off characteristic, anxiety, dyspnea, and polyuria. This type of tachycardia may often be terminated by vagal maneuvers. Although the clinical presentation of AVRT is quite similar to AV-nodal reentrant tachycardias, the correct diagnosis is often facilitated by analyzing a standard 12-lead ECG at normal heart rate showing ventricular preexcitation. Curative catheter ablation of the AP represents the therapy of choice in symptomatic patients. This article is the fourth part of a series written to improve the professional education of young electrophysiologists. It explains pathophysiology, symptoms, and electrophysiological findings of an invasive EP study. It focusses on mapping and ablation of accessory pathways.

  11. 15-åringers opplevelser av overvekt hos jevnaldrende, en fenomenologisk-hermeneutisk studie

    2011-06-01

    Full Text Available Hensikten med denne studien er å studere hvordan 15-åringer opplever overvekt hos jevnaldrende. Datamaterialet består av dybdeintervju med syv ungdommer. Det er benyttet fenomenologisk-hermeneutisk analyse. Ungdommene opplever å stå i en posisjon mellom makt og avmakt. I denne mellomposisjonen framkommer det at ungdommene distanserer seg ved hjelp av relasjonell makt, men samtidig setter de seg selv i en avmaktssituasjon i forhold til ungdomskulturens spilleregler. Ungdommene moraliserer ved å skape en situasjon hvor de underkjenner overvektige, samtidig mangler de ytterligere sanksjoneringsmuligheter. Rangordninger skapes gjennom at ungdommene degraderer overvektige, men de må selv også innordne seg i egen kultur. Ungdommene fratar overvektige sitt menneskeverd gjennom å redusere menneskelige egenskaper og gjør dem til objekt. Gjennom denne objektiviseringen setter de seg selv utenfor det å få tak i overvektiges refleksjons- og erfaringsgrunnlag.

    UKÄ:s utvärdering av biomedicinutbildningar visar på en mycket varierad kvalitet. Nio av 21 utbildningar håller toppklass medan mer än hälften bedöms vara bristande. 21 utbildningar inom biomedicin har satts under lupp. Kvaliteten bedöms som vanligt efter en tregradig skala: mycket hög kvalitet...... biomedicinstudenternas förmåga att göra etiska bedömningar. Flera utbildningar har inte kunnat visa att studenterna kan göra etiska bedömningar. De har heller inte kunnat visa att studenterna känner till vilka regelverk som gäller vid etikprövning. Detta är särskilt allvarligt eftersom man inom biomedicin genomför...

    Bakgrund:CAPM räcker i flera tillfällen inte till för att estimera framtida avkastning. Vissa av prisavvikelsernafrån CAPM är väldokumenterade och har bestått över tid, vilket har lett till uppkomsten avkorrigerande faktorer. En modell som använder sig av två sådana korrigerande faktorer är Fama ochFrenchs tre-faktormodell. Den har testats flertalet gånger på den svenska marknaden där den visat gehögre förklaringsgrader än CAPM. År 2012 samt år 2014 presenterades två nya multifaktormodeller,s...

    This report summarizes the results of the Load Control System Reliability project (DOE Award DE-FC26-06NT42750). The original grant was awarded to Montana Tech April 2006. Follow-on DOE awards and expansions to the project scope occurred August 2007, January 2009, April 2011, and April 2013. In addition to the DOE monies, the project also consisted of matching funds from the states of Montana and Wyoming. Project participants included Montana Tech; the University of Wyoming; Montana State University; NorthWestern Energy, Inc., and MSE. Research focused on two areas: real-time power-system load control methodologies; and, power-system measurement-based stability-assessment operation and control tools. The majority of effort was focused on area 2. Results from the research includes: development of fundamental power-system dynamic concepts, control schemes, and signal-processing algorithms; many papers (including two prize papers) in leading journals and conferences and leadership of IEEE activities; one patent; participation in major actual-system testing in the western North American power system; prototype power-system operation and control software installed and tested at three major North American control centers; and, the incubation of a new commercial-grade operation and control software tool. Work under this grant certainly supported the DOE-OE goals in the area of “Real Time Grid Reliability Management.”

  17. Microprocessor hardware reliability

    Microprocessor-based technology has had an impact in nearly every area of industrial electronics and many applications have important safety implications. Microprocessors are being used for the monitoring and control of hazardous processes in the chemical, oil and power generation industries, for the control and instrumentation of aircraft and other transport systems and for the control of industrial machinery. Even in the field of nuclear reactor protection, where designers are particularly conservative, microprocessors are used to implement certain safety functions and may play increasingly important roles in protection systems in the future. Where microprocessors are simply replacing conventional hard-wired control and instrumentation systems no new hazards are created by their use. In the field of robotics, however, the microprocessor has opened up a totally new technology and with it has created possible new and as yet unknown hazards. The paper discusses some of the design and manufacturing techniques which may be used to enhance the reliability of microprocessor based systems and examines the available reliability data on lsi/vlsi microcircuits. 12 references.

    Full Text Available Background: Today it is virtually impossible to operate alone on the international level in the logistics business. This promotes the establishment and development of new integrated business entities - logistic operators. However, such cooperation within a supply chain creates also many problems related to the supply chain reliability as well as the optimization of the supplies planning. The aim of this paper was to develop and formulate the mathematical model and algorithms to find the optimum plan of supplies by using economic criterion and the model for the probability evaluating of non-failure operation of supply chain. Methods: The mathematical model and algorithms to find the optimum plan of supplies were developed and formulated by using economic criterion and the model for the probability evaluating of non-failure operation of supply chain. Results and conclusions: The problem of ensuring failure-free performance of goods supply channel analyzed in the paper is characteristic of distributed network systems that make active use of business process outsourcing technologies. The complex planning problem occurring in such systems that requires taking into account the consumer's requirements for failure-free performance in terms of supply volumes and correctness can be reduced to a relatively simple linear programming problem through logical analysis of the structures. The sequence of the operations, which should be taken into account during the process of the supply planning with the supplier's functional reliability, was presented.

    {sup 18}F-Florbetapir (AV-45/Amyvid) is a novel positron emission tomography (PET) tracer for imaging plaque pathology in Alzheimer's disease (AD), while PET images of fluorodeoxyglucose (FDG) for cerebral glucose metabolism can provide complementary information to amyloid plaque images for diagnosis of AD. The goal of this preliminary study was to investigate the perfusion-like property of relative cerebral blood flow estimates (R{sub 1}) and summed early-phase AV-45 images [perfusion AV-45 (pAV-45)] and optimize the early time frame for pAV-45. Dynamic AV-45 PET scans (0-180 min) were performed in seven subjects. pAV-45, late-phase AV-45, and FDG images were spatially normalized to the Montreal Neurological Institute template aided by individual MRI images, and the corresponding standardized uptake value ratio (SUVR) was computed. The R{sub 1} images were derived from a simplified reference tissue model. Correlations between regional and voxelwise R{sub 1} and the corresponding FDG images were calculated. An optimization of time frames of pAV-45 was conducted in terms of correlation to FDG images. The optimal early time frame was validated in a separate cohort. The regional distribution in the R{sub 1} images correlated well (R = 0.91) to that of the FDG within subjects. Consistently high correlation was noted across a long range of time frames. The maximal correlation of pAV-45 to FDG SUVR of R = 0.95 was observed at the time frame of 1-6 min, while the peak correlation of R = 0.99 happened at 0-2 min between pAV-45 and R{sub 1}. A similar result was achieved in the validation cohort. Preliminary results showed that the distribution patterns of R{sub 1} and pAV-45 images are highly correlated with normalized FDG images, and the initial 5-min early time frame of 1-6 min is potentially useful in providing complementary FDG-like information to the amyloid plaque density by late-phase AV-45 images.
