    1995-09-01

    Light electric-powered vehicles still exist in the shadow beside gasoline-operated automobiles. One reason for this lies in the economic recession, another in the marketing strategy for the Swatch vehicle due to be put on the market shortly. The report gives an overview of the light vehicles shown this year at Berne`s solar vehicle exhibition. TWIKE, an innovative, energy-efficient tricycle, is particularly pointed out. (BWI) [Deutsch] Leicht-Elektromobile fristen leider immer noch ein Schattendasein neben den benzinbetriebenen Automobilen. Der Grund dafuer ist neben der rezessiven Wirtschaftstendenz auch in der Marketing-Strategie fuer das zu erwartende Swatch-Mobil zu sehen. Der vorliegende Beitrag gibt einen Ueberblick ueber die auf dem diesjaehrigen Solarsalon in Bern gezeigten Leichtmobile. Besonders hervorgehoben wird dabei TWIKE, ein innovatives, energieeffizientes Dreirad. (BWI)

    Bei dem Entwurf von anwendungsspezifischen integrierten Schaltungen muss ein Entwickler zusätzliche Funktionen integrieren und die zunehmende Komplexität bewältigen. Für die Reduzierung der Kosten bleibt weiterhin die Verkürzung der benötigten Entwicklungszeit ein Ziel. Ein entscheidender Faktor dabei ist die zuverlässige Absicherung von Entwurfsentscheidungen in einer frühen Entwurfsphase. In der vorliegenden Arbeit wird eine Methode vorgestellt, die eine Bewertung von Entwurfsentscheidungen bei Systemmodellen mittels automatisch ermittelter Indikatoren ermöglichen soll. Die Systemmodelle können mit der Entwurfsumgebung MATLAB/Simulink oder in SystemC beschrieben sein.

    Emissions from construction products impact the quality of indoor air considerably. The AgBB scheme is employed to evaluate the emissions of volatile organic compounds (VOC) from construction products. The hygienic evaluation according to the AgBB scheme requires product-specific measuring procedures. These exist for a range of products. They have been validated in co-operation with several research and testing institutes and have been included in the criteria for awarding the eco-label Blue Angel. The evaluation is, however, stricter and generally has lower limits. VOC emissions and odours can cause health problems so sensory testing is an important element in the evaluation of construction products and has - for reasons of precaution - been set down in the AgBB scheme. The main goal of the project is to derive a method of sensory evaluation and limits for awarding the Blue Angel and for the AgBB scheme. Based on the research conducted (see Chapter 5 Results and Discussion), perceived intensity and hedonics are suggested for the evaluation method. The derivation of limits for the sensory evaluation on the 28th day was effected in the present study through the additional questioning of the test subjects on the reasonability of a sample. For the Blue Angel, there could be different limits of perceived intensity and hedonic for each group of products. A preliminary suggestion for possible limits - here for all product groups - is a perceived intensity of 7 pi (5 pi + 2 pi as confidence coefficient, Chapter 5.1.5. ''Minimum Requirements for the Size of Test Groups'') and -1 (0{+-}0.8, rounded to -1) for the hedonic value (see Figure 6-1). (orig.)

    Within the framework of the R and D project ``Mechanical-biological waste conditoning in combination with thermal processing of partial waste fractions``, numerous measurements to determine gaseous and liquid emissions were carried out. These measurements reveal the environmental impact of different treatments and different inputs. They further permit to verify the quality of a treatment. Particularly interesting for the purpose of the project were the total emissions of the considered process combinations. The paper reports the outcome of emission measurements and indicates the variants of process combinations for which the emissions were aggregated. First results of the evaluation of gaseous and liquid emissions are given for these variants. (orig.) [Deutsch] Im Zuge des Forschungs- und Entwicklungsvorhabens `Mechanisch-biologische Restmuellbehandlung unter Einbindung thermischer Verfahren fuer Teilfraktionen` sind zahlreiche Emissionsmessungen bezueglich der luft- und wasserseitigen Emissionen durchgefuehrt worden. Die Ergebnisse dieser Messungen geben Aufschluss ueber die Umweltauswirkungen der verschiedenen Behandlungsverfahren bei unterschiedlichem Input. Des weiteren kann durch sie die Guete des Prozesses ueberprueft werden. Im Projekt interessant sind aber insbesondere die Gesamtemissionen der betrachteten Verfahrenskombinationen. Im folgenden werden die durchgefuehrten Emissionsmessungen und die Varianten der Verfahrenskombinationen, fuer die die Emissionen aggregiert wurden, dargestellt. Dnach werden erste Ergebnisse der Bewertung der luft- und wasserseitigen Emissionen fuer diese Varianten praesentiert. (orig.)

    The structural mechanics computer code PROST of GRS was extended in the project RS1516 for more applications and improved usability. The fracture mechanical features were extended by supplementary structure types, additional crack geometries, refined failure criteria, and temperature-dependent parameters. The consideration of in-service inspections was revised, while upgraded fatigue analyses enhance the quality of the computed results. The modeling of leakage rates was ameliorated by coupling the WinLeck computer code of GRS for leak rate computation, leading to better predictions of these features. Additional probabilistic techniques were implemented in PROST, which allow a more accurate quantification of risks. PROST's validation was done within in the project by two international benchmark studies. Analytical techniques for fracture mechanical parameters and in-service inspections in probabilistic crack-growth analyses were in the focus of the comparative studies. In addition, diverse test cases are analyzed, allowing the comparison with published studies. The available methodology for leak rate analysis was used for the planning of upcoming measurements. The PROST code has a graphical user interface, is accompanied by a detailed documentation and is made available for external users. Thus, it is a qualified tool for fracture mechanical studies, taking into account nuclear safety standards.

  8. Evaluation of anthropogenic urban soils. Final report; Bewertung anthropogener Stadtboeden. Abschlussbericht

    The research project `Evaluation of Anthropogenic Urban Soils` was subsidized by the German Federal Ministry of Education, Science, Research and Technology and adviced by the working group `Stadtboeden` of the German Society of Soil Science. It was realized as a cooperation between the universities of Berlin (TU), Halle-Wittenberg, Hohenheim, Kiel and Rostock and had three objectives: - to characterize soils developed from anthropogenic substratums (`urban soils`), - to figure out distribution patterns of such soils and - to verify whether urban soils could be evaluated according to their filtering and habitat function in the same way as soils developed from natural parent material. Evaluation methods based on easily obtainable field data had to be adapted to `urban soils` respectively developed anew. For that reason some typical soils of anthropogenic lithogenesis had to be examined between 1993 and 1996 both on their importance as habitats for plants and soil organisms and on their filtering, buffering and transforming capacities for organic and inorganic pollutants. Accordingly representative `urban soils` were gathered in the towns of Berlin, Eckernfoerde, Essen, Halle, Kiel, Rostock and Stuttgart; these soils had developed from technogenic substratums (brick and mortar debris, municipal waste, ashes, slag, sludge) and redeposited alkaline resp. acidic natural substratums (mud, coal mine and coking plant deposits). Some of the soils were influenced by ground water, and all soils developed from the same kind of parent material belonged to different stages of development. (orig./SR) [Deutsch] Ziele des vom BMBF gefoerderten und vom Arbeitskreis Stadtboeden der Deutschen Bodenkundlichen Gesellschaft beratenen Verbundprojektes `Bewertung anthropogener Stadtboeden` waren die Charakterisierung von Boeden anthropogener Substrate, die exemplarische Ermittlung des Verteilungsmusters derartiger Boeden und die Pruefung, inwieweit sie sich aehnlich den Boeden natuerlicher

    All details of the MPA full-scale vessel relevant to non-destructive testing under the Agreement on Scientific and Technological Cooperation were compiled. The BWR pressure vessel (AEG/KWU, material 1.6751-22 NiMoCr 37 - A 508 Cl.2) was complemented by a PWR supporting ring (material 1.6310 - 20 MnMoNi 55). In particular, all documents related to failure insertion and the results of testing programmes carried out so far were evaluated. In addition, two drill cores were taken from the cylindrical lower part and tested metallographically. The test results of three more drill cores and of insertion 95 from the PISC programme were also evaluated. The definite reference data set thus created of the failures selected and studied under the programme of scientific and technological cooperation is set out in a table. It serves as a basis for the evaluation of the test results achieved by the participants in the NDT ring test. (orig./HP) [Deutsch] Alle fuer die zerstoerungsfreien Pruefungen im Rahmen des WTZ-Abkommens relevanten Einzelheiten ueber den MPA-Grossbehaelter wurden zusammengestellt. Der SWR-Druckbehaelter (AEG/KWU, Werkstoff 1.6751 - 22 NiMoCr 37 - A 508 Cl. 2) wurde durch einen DWR-Traegerring (Werkstoff 1.6310 - 20 MnMoNi 55) ergaenzt. Insbesondere wurden saemtliche Unterlagen ueber die Fehlereinbringung sowie die Ergebnisse der bisher durchgefuehrten Pruefprogramme ausgewertet. Ausserdem wurden zwei Bohrkerne aus dem zylindrischen Unterteil entnommen und metallografisch untersucht. Die Untersuchungsergebnisse von weiteren drei Bohrkernen und des Einschubs 95 aus dem PISC-Programm wurden ebenfalls verwertet. Der so geschaffene, endgueltige Referenz-Datensatz der fuer das WTZ-Programm ausgewaehlten und geprueften Fehler ist tabellarisch aufgelistet. Er dient als Grundlage fuer die Auswertung der Pruefergebnisse der Teilnehmer an dem eigentlichen ZfP-Ringversuch. (orig./HP)

    The report presents a summary of the project of the above title (EFAS project). While earlier projects focused on the technical side, EFAS is the first to present a systematic analysis, presentation and evaluation of the parameters influencing driving support systems. With the aid of a systemic analysis, the key influencing factors are defined and analyzed, and three scenarios are developed which take account of user-oriented, organizational, operational, technical, infrastructural and legal aspects. The scenarios are evaluated with the aid of driving and traffic simulations in the fields of humans, organization and technology, and actions are recommended on this basis for driving support systems in cargo transport. [German] Der Bericht fasst die Ergebnisse des Projektes ''Einsatzszenarien fuer Fahrerassistenzsysteme im Gueterverkehr'' (EFAS) zusammen. Bisher wurde die Thematik Fahrerassistenzsysteme hauptsaechlich auf der Seite der Fahrzeugtechnik vorangetrieben. Das Projekt EFAS stellt nun zum ersten Mal eine umfassende Analyse, Darstellung und Bewertung dar. Mit Hilfe einer systemischen Analyse werden die wesentlichen Einflussfaktoren fuer die Einbindung von Fahrerassistenzsystemen in das Gesamtsystem ''Verkehr'' bestimmt und untersucht. Hieraus werden drei Einsatzszenarien entwickelt, die nutzerbezogene, organisatorische, betriebliche, fahrzeugtechnische, infrastukturelle und rechtliche Aspekte zu Zukunftsbildern zusammenfuegen. Die Szenarien werden mit Hilfe von Fahr- und Verkehrssimulationen in den Bereichen Mensch, Organisation und Technik bewertet. Aus den Ergebnissen werden konkrete Handlungsempfehlungen fuer den Einsatz von Fahrerassistenzsystemen im Strassengueterverkehr abgeleitet. (orig.)

DM eine Zweiphasen-Dichtwand, eine neue kombinierte Oberflaechenabdichtung und wegen der fehlenden Basisabdichtung eine Deponie-interne Drainage mit Sickerwasserentnahme eingerichtet. Begleitend zur Sanierung wurden 3-dimensionale Modellberechnungen zur Grundwasserstroemung im Bereich der Deponie fuer unterschiedliche Sicherungsmassnahmen sowie 2-dimensionale Modelle zur Bewertung des Schadstoffabstroms im Grundwasserleiter vorgenommen. Trotz der fehlenden Basisabdichtung konnte die Effektivitaet der Massnahme im Deponiebereich nachgewiesen und Optimierungsmoeglichkeiten aufgezeigt werden. Fuer das Umfeld konnten die recht guenstigen hydrogeologischen Barriereeigenschaften mit der geringen Schadstoffausbreitung herausgearbeitet werden. (orig.)

Aufbauend auf diesen Ergebnissen wurde im vorliegenden Vorhaben eine verfahrenstechnische Bewertung dieser Absorptionsmittel am Beispiel konkreter industrieller Aufgabenstellungen durchgefuehrt. Als Bewertungsinstrumentarium dient ein Simulationsprogramm fuer einen typischen Absorptions-/Desorptionsprozess, das die Auswahl von Waschfluessigkeiten, die einen wirtschaftlichen Betrieb gewaehrleisten, und die Bestimmung der optimalen Betriebsbedingungen ermoeglicht. Neben Glykolethern haben sich Adipinsaeure-bis-2-ethylhexylester und Propylencarbonat als besonders geeignet erwiesen. Weiterhin wurden die Aktivitaetskoeffizienten von verschiedenen Loesungsmitteln in Glykolether in Anwesenheit von Wasser gemessen. Es zeigte sich dabei, dass Wasser keinen nennenswerten Einfluss auf die Absorptionsleistung aufweist. (orig.)

    Building products for internal spaces can act as significant emission sources of volatile organic substances and seriously affect the quality of the room air. Public law requirements for building products regarding health protection of occupants are anchored in the European Construction Products Directive (89/106/EEC) and through implementation in national law, for example the Building Products Act or the regional building regulations. The European Construction Products Directive defines the requirements relating to health, hygiene and the environment, which are elaborated in Baseline Requirements Document No.3 of the European Commission. In particular, they include the requirements regarding emissions of noxious substances from building products and the avoidance and limitation of volatile organic connections (VOC) in internal spaces. Since no official procedure currently exists for the implementation of these health-related requirements, the German Committee for Health-related Evaluation of Building Products (AgBB) substantiated and published test criteria for the assessment of potential health effects of volatile organic compounds (VOC and SVOC emissions) from building products. In line with building laws, this procedure provides standardised test procedures and health-related assessment criteria with the aim of limiting emissions of volatile organic compounds from building products. Against the background of building authority requirements, this objectifiable and particularly transparent approach will enable consumers, architects, planners and building product manufacturers to evaluate building products for internal spaces at an early stage for their relevance in terms of pollutants and emissions, and to use them appropriately.

    For a short time now, the L-LAB (Light-LABoratory), a joint research facility of Hella KG and the University of Paderborn, has had a simulator available which allows the evaluation of driver assistance systems and the optimisation of man-machine interfaces. It is an interactive night driver simulator, which can be used to visualise any type of headlamp beam pattern true to the original. A Smart is used as the input medium; image projection is via a 3-channel high-performance beamer projection system onto large screens. Alongside synthetic roads, there is also a digitalised course available, approx. 10 km long, the original of which is actually used by Hella as a proving ground. Road safety indicators can be recorded directly and indirectly. For example, obstacles which suddenly appear force drivers to apply the brakes. The stopping distance required can be interpreted as a direct indicator for safety. In addition, an eye tracking system is used to record the eye movements of the test subjects, which allows additional road safety indicators to be derived. Comparative investigations between the digitalised proving ground and reality allow validation of the simulator. This year, a comprehensive study will be made to optimise the man-machine interface in connection with infrared vision systems in vehicles. The advantages of simulation are not only in the economical implementation possibilities and control of the variables, but also the fact that properties of driver assistance systems can be evaluated which are not even technically possible yet in reality. The use of the simulator developed here is not limited to tests connected with the visibility of obstacles, however. Rather, it allows the investigation and evaluation of a large range of potential driver assistance systems. (orig.)

    Under the roof of SINTAP (Structural Integrity Assessment Procedures for European Industry), a European BRITE-EURAM project, a study is being carried out into the possibility of establishing on the basis of existing models a standard European flaw assessment method. The R6 Routine and the ETM are important, existing examples in this context. The paper presents the two methods, explaining their advantages and shortcomes as well as common features. Their applicability is shown by experiments with two pressure vessels subject to internal pressure and flawed by a surface crack or a through-wall crack, respectively. Both the R6 Routine and the ETM results have been compared with results of component tests carried out in the 1980s at TWI and are found to yield acceptable conservative, i.e. sufficiently safe, lifetime predictions, as they do not give lifetime assessments which unduly underestimate the effects of flaws under operational loads. (orig./CB) [Deutsch] Gegenwaertig wird im Rahmen von SINTAP (Structural Integrity Assessment Procedures for European Industries), einem europaeischen BRITE-EURAM-Projekt geprueft, inwieweit auf der Grundlage vorhandener Modelle eine einheitliche europaeische Fehlerbewertungsmethode erstellt werden kann. Eine zentrale Stellung kommt dabei Verfahren wie der R6-Routine und dem ETM zu. In der vorliegenden Arbeit wurden beide Methoden vorgestellt, wobei ihre Vor- und Nachteile, aber auch ihre Gemeinsamkeiten herausgearbeitet wurden. Die Anwendung wurde an zwei innendruckbelasteten Behaeltern mit Oberflaechen- bzw. wanddurchdringendem Riss demonstriert. Sowohl R6-Routine als auch ETM ergaben im Vergleich mit am TWI zu Beginn der 80er Jahre durchgefuehrten Bauteilexperimenten eine vertretbare konservative Vorhersage, d.h. eine nicht allzu grosse Unterschaetzung der ertragbaren Last der Bauteile.

    Concepts for identifying and evaluating operative actions were applied and compared in a dissertation of the Institute of Process and Plant Engineering of TU Berlin University. A plant of PCK Raffinerie GmbH at Schwedt, Oder was used for the investigations. 'Operative actions' in this context were defined as any interference of human operators with the technical system. The findings were to be used by plant operators and licensing authorities for the double purpose of detecting safety gaps and of ensuring plant safety in normal operation and in case of disturbances, taking into account the human factor. [German] Im Rahmen einer Diplomarbeit am Institut fuer Prozess- und Anlagentechnik der Technischen Universitaet Berlin wurden anhand einer verfahrenstechnischen Anlage zur Veredelung von Erdoelprodukten der PCK Raffinerie GmbH in Schwedt/Oder verschiedene Konzepte zur Darstellung und Bewertung von Bedienhandlungen angewandt und verglichen, wobei als Bedienhandlung in diesem Zusammenhang jeder die Prozessfuehrung betreffende Eingriff des Menschen in das technische System angesehen wird. Dabei sollte durch eine angemessene Darstellung der Bedienhandlungen eine verbesserte Uebersicht sowohl fuer den Anlagenbetreiber als auch fuer die ueberwachende Behoerde geschaffen werden, so dass moegliche Sicherheitsluecken erkannt, aber auch die Sicherheit der Anlage im normalen sowie gestoerten Betrieb unter Beruecksichtigung des Bedieners nachgewiesen werden koennen.

    The aim of this work is starting from the investigation of the technical development prospects along the fuel delivery chain to develop a suitable reproducible tool for the analysis and evaluation of future biofuel policies and on selected fuel options from solid biomass (1. bioethanol by biochemical fermentation, 2. Fischer-Tropsch-Diesel by thermochemical gasification, and 3. Bio-Synthetic Natural Gas (Bio-SNG) by thermochemical gasification). For this it is necessary for these biofuels in accordance with the current technology state the essential perspectives for the practical implementation taking into account the short, medium and long term (e.g. time horizon for implementation in up to 5 years, in about 10 to 15 years, or about 20 to 25 years) to identify possible technical options. [German] Ziel dieser Arbeit ist es, ausgehend von der Untersuchung der technischen Entwicklungsperspektiven entlang der Kraftstoffbereitstellungskette ein geeignetes reproduzierbares Werkzeug fuer die Analyse und Bewertung zukuenftiger Biokraftstoffkonzepte zu entwickeln und auf ausgewaehlte Kraftstoffoptionen auf Basis fester Biomasse (hier Bioethanol ueber die biochemische Fermentation, Fischer-Tropsch-Diesel ueber die thermochemische Vergasung und Bio-Synthetic Natural Gas (Bio-SNG) ueber die thermochemische Vergasung) anzuwenden. Dazu gilt es fuer diese Biokraftstoffe unter Beachtung des aktuellen Technikstandes die wesentlichen Perspektiven fuer die praktische Umsetzung unter Beruecksichtigung der kurz-, mittel- bis langfristig (d.h. Zeithorizont fuer die Realisierung in bis zu 5 Jahren, in etwa 10 bis 15 Jahren bzw. in etwa 20 bis 25 Jahren) denkbaren technischen Moeglichkeiten zu identifizieren.

    The work aims at an ecological valuation of air pollutant emissions and energy consumption as particularly relevant aspects of waste treatment and waste combustion plants, based on new scientific results, in order to draw up ecological budgets and make system comparisons in waste treatment. The target set is particularly effectively achieved by the following: documentation and scientific derivation of relevant boundary conditions, careful surveying and data processing for the purpose of making up an ecological budget, and objective valuation and interpretation of results. The high transparency of the methodics should be emphasized. They make the results obtained conclusive and verifiable. (orig.) [Deutsch] Ziel der vorliegenden Arbeit ist die oekologische Bewertung der besonders relevanten Aspekte Abluftemissionen und Energieverbrauch von MBA und MVA auf Basis aktueller Forschungsergebnisse als Grundlage fuer Oekobilanzen und Systemvergleiche zur Restabfallbehandlung. Diese Zielvorgabe wird durch die Dokumentation und wissenschaftliche Herleitung relevanter Rahmenbedingungen, sorgfaeltige Erhebung und Aufbereitung der Daten unter Gesichtspunkten der Erstellung einer Oekobilanz und letztendlich aufgrund der objektiven Bewertung und Interpretation der Ergebnisse im besonderen Masse erreicht. Besonders hervorzuheben hierbei ist die hohe Transparenz bei der methodischen Vorgehensweise. Die ermittelten Ergebnisse sind somit nachvollziehbar und ueberpruefbar. (orig.)

    The main targets of the project, increased calibration accuracy for solar cells and moduls and the energy rating for solar moduls was achieved. Now the Fraunhofer can make secondary calibration of conventionell solar Cells with 1,5% accuracy, the Physikalisch-Technische Bundesanstalt Braunschweig (PTB) can make primary calibration of reference cells with 0,5% accuracy. The measurement accuracy for solar moduls was increased from 5% to 2,5%. For the STC calibration and characterization of solar moduls an extensive measurement equipment was established. Several efficient simulation tools have been developed for the estimation of seasonal energy efficiencies. The estimation based on recorded climate and module data. The calculated yearly efficiency correspond good with measured values in selected PV - systems from the 'German 1.000 roof program'. (orig.) [German] Die drei uebergeordneten Ziele des Projekts, naemlich die Erhoehung der Kalibriergenauigkeit von Referenzzellen mit Rueckfuehrung auf internationale Normale, die Praezisionskalibierung von Modulen und die energetische Bewertung von Modulen, wurden erreicht. Fuer die Sekundaerkalibrierung konventioneller Technologie kann das Fraunhofer ISE heute eine Messunsicherheit von nur 1,5% angeben, die Physikalisch-Technische Bundesanstalt Braunschweig (PTB) kalibriert ihre Referenzzellen jetzt mit 0,5% Unsicherheit. Fuer marktuebliche PV-Module wurde der Messfehler von zuvor 5% auf 2,5% reduziert. Fuer die STC-Kalibrierung von PV-Modulen und Charakterisierung unter realistischen Bezugsbedingungen wurde ein umfangreicher Geraetepark aufgebaut. Leistungsfaehige Modellierungswerkzeuge wurden bereitgestellt, die es erlauben, anhand von gemessenen Klimadaten oder von Klimamodellen gewonnenen Zeitreihen, sowie der gemessenen Modulparameter saisonale Wirkungsgrade zu ermitteln. Die Aussagen dieser Jahreswirkungsgradrechnungen ergaben eine gute Uebereinstimmung mit ausgewaehlten Ergebnissen des begleitenden

    In many fields of geotechnical engineering geosynthetics have established itself as an alternative to common used earth materials. Particularly in landfill sealing systems many different types of geosynthetics are used together. In embankments geosynthetics form inclined planes. The safety against sliding must be proved for all contact surfaces. For this purpose, the knowledge of the friction behavior of the geosynthetics is required. Normally, the friction behavior is modeled analytically with the Coulomb failure criterion. The Coulomb friction parameters usually must be determined experimentally. In spite of the good state of the art and numerous studies into geosynthetics, in detail, there are still issues relating to the determination of friction behavior of geosynthetics, to the application of the Coulomb failure criterion and to the assessment of the friction parameters with a view to the time- and temperature-dependent behavior of synthetics. The main objective of this work is to contribute to a reliable determination of the friction behavior and to a correct assessment of the evaluated test results as the basis for a reliable and economical dimensioning of structures with geosynthetics. For this, the measurement technique of a standard large direct shear box was upgraded by the author, so that the effective normal stress can be measured below the test surface. Also tests with very small normal stresses can be carried out with this modification. Furthermore, a force-controlled test device was designed for studies of the influences arising from long-term combined compressive and shear loads and temperature. Based on experimental investigations inadequacies in the current experimental procedure are identified. In addition, the impact of factors are quantified, which are often ignored or considered to be marginal in practice. With further experimental investigations it is demonstrated that the linear Coulomb failure criterion is valid for limited normal stress

    Besides the upper abdominal parenchymal organs, the increasing application of cross-sectional imaging has also led to a rising number of incidental findings in the kidneys, adrenal glands, adnexa uteri, the gastrointestinal tract, mesentery and abdominal lymph nodes. Abdominal computed tomography investigations often show unexpected findings without any correlating symptoms. The growing clinical relevance is due to the large number of incidental findings as well as an increasing awareness of ethical and socioeconomic factors. When interpreting radiological findings not only morphological criteria but also individual risk factors of the patient and the clinical context are of great importance. The aims of this article are the description and evaluation of frequent incidental findings detected by computed tomography and to provide information about management recommendations. (orig.) [German] Neben den parenchymatoesen Oberbauchorganen hat der zunehmende Einsatz von Schnittbildverfahren zu einer vermehrten Anzahl von Zufallsbefunden der Nieren, Nebennieren, Adnexe, des Gastrointestinaltrakts, Mesenteriums und der intraabdominellen Lymphknoten gefuehrt. Abdominelle CT-Untersuchungen zeigen haeufig unerwartete Befunde ohne korrelierende Symptomatik. Die steigende klinische Relevanz ist einerseits auf die Zunahme inzidenteller Pathologien und andererseits auf ein wachsendes Bewusstsein ethischer und soziooekonomischer Faktoren zurueckzufuehren. Bei der radiologischen Interpretation sind neben morphologischen Kriterien sowohl die Einbeziehung der individuellen Risikofaktoren des Patienten als auch der klinische Gesamtkontext von grosser Bedeutung. Das Ziel dieses Artikels ist eine Beschreibung und Bewertung der in der Computertomographie detektierten genannten Zufallsbefunde sowie weiterer Managementempfehlungen. (orig.)

    Safety assessment of reactor components has to encompass the nozzles, as in the event of a LOCA, the nozzle areas are subject to heavy thermal stresses due to the low temperature there of the cooling agent. The paper refers to three-dimensional, elasto-plastic FEM analyses of the integer RPV and calculations of the J-integral for various crack locations and geometries, for derivation of realistic transients. The J-integral and K values calculated with FEM have been compared with stress intensity factors determined by means of enhanced analytical methods. Calculations for description of the integer nozzle yield plastifications in the cladded and the ferritic areas, so that the K concept of linear-elastic fracture mechanics is restricted in applicability. For postulated cracks beneath the integer cladding, J-integral values are determined which are below the initiating value J{sub 1} of the material used, which excludes crack initiation. For the largest postulated, 20 mm deep surface crack and through-cladding damage, a crack growth of 0.1 mm is derived according to the crack resistance curve. The analytical method for calculating the stress intensity factors has been expanded to also include application to evaluation of nozzle edge cracks under the cladding.

    The contribution under consideration reports on the performance of dust collectors for wood fires with respect to various parameters. Thus, the knowledge of the possibilities of the reduction of dust emissions should be improved by means of electrostatic deposition methods, and the assessment of practicability is to be enabled. To this end, several months of field testing of ten representative fireplaces was performed.

    On the basis of the dynamic growth of biogas plants in Germany the fertilization with biogas residues has obtained an important role for recirculation of plant nutrients, particularly with regard to nitrogen. In this work the effect of N nutrition with biogas residues was assessed in a 3-year on-field trial conducted at four sites throughout Bavaria. The fertilizing effects were tested by varying rate and time of biogas residues application, using different application techniques and the addition of nitrification inhibitors on several crops. The biogas residues achieved mineral fertilizer equivalents of 30 - 45 %. Overall, the untreated biogas residues showed a slightly increased N efficiency compared to cattle manure, whereas particularly site-dependent differences resulted in large differences in N efficiency of biogas residues.

    In order to evaluate and optimize programmes of measures according to EU-Water framework directive a methodology has been developed which consists of three consecutive parts. In the first part the interrelations between matter inputs (contaminations), observed matter concentrations in groundwater and the hydrogeological system are analyzed based on a ''conceptual model''. Based on this a consistent evaluation of the extent of pollutant reduction necessary to reach good status of groundwater is carried out in the second part. The third part is an evaluation of the time gap between the introduction of a measure and its impact on the status of groundwater. The derived methodology is predominately based on digital datasets as input data which are available on the level of Germany's Federal States. Adapted to the sources of contamination of groundwater the methodology was successfully tested for diffuse nitrate sources in two regions in Lower Saxony/Northrhine-Westfalia and Hesse and for point sources in one region in Brandenburg.

    The air pollution especially caused by car traffic continues to increase. Since in areas near zones with a high volume of traffic immissions can occur, which effect the health, so-called ``test values`` for nitrogen oxides, benzene and diesel exhaust particulates are recommended in a ``Verordnung zur Durchfuehrung des Bundes-Immissionsschutz-Gesetzes`` (Directive for the enforcement of the Federal Law for the protection against immissions). When these values are exceeded, the measurements concerning the planing of traffic or cities must be re-checked. At present these values are generally exceeded in streets with a high volume of traffic. The data basis about the numerous effects, which each parameter has on the health will be presented and critically assessed in this work. Nitrogen oxides can cause irritations of the mucous membrane and foster asthma, allergies and infections of the respiratory tracts. This can already occur at concentrations which are measured under unfavourable conditions in areas near zones with a high volume of traffic. It has been proved that benzene causes bone marrow damages, leukaemia and lymphomas at human beings, when concentrations are measured which exceed those in areas with a high volume of traffic by approx. a 1000 times. Even though latest investigations may lead to the conclusion, that diesel exhaust particulates have a carcinogenic effect on human beings, so far it has been proved exclusively in animal experiments, that diesel exhaust particulates foster lung cancer. However, this already occurs at concentrations, which only exceed by approx. 50 times the values, that aremeasured in areas with an unfavourable environmental pollution. According to careful assessments 40 cases of leukaemia and 580 cases of lung cancer must be expected per one million exposed people, when the contaminants benzene and diesel exhaust particulates reach the test values and do not exceed them.

    We estimated ambient air concentrations of platinum by applying dispersion models as well as recent emission factors that have been derived from engine test bench experiments with three-way, monolith-type catalytic converters. Predicted concentrations in various exposure scenarios range from 4 pg/m{sup 3} (street canyon, typical conditions) up to 112 pg/m{sup 3} (express-motorway, severe conditions). These values agree well with the few measurements of platinum ambient air concentrations. Platinum is emitted from catalytic converters in very small amounts (ng/km range) and is mainly in the oxidation state 0 (elemental platinum). The nanocrystalline platinum particles are attached to {mu}m-sized aluminum oxide particles. Whether free ultrafine platinum particles may be emitted and result in biological effects has not been studied sufficiently. Hence, risk assessment can only be based on the respiratory sensitizing effects of halogenated platinum salts, although this can be considered a very sensitive endpoint. The presence of such compounds in the soluble fraction ({<=}1%) of the total platinum emissions as well as their secondary formation from platinum particles cannot principally be excluded. Our risk assessment is based on recent occupational studies in a catalytic converter production plant, from which a conservative, no effect level (NOEL) of 1.5 ng/cm{sup 3} can be derived for soluble platinum. In a (reasonable) worst case approach we assume that halogenated platinum salts comprise 1% (0.1%) of the total platinum emissions. Applying an unsafety factor of 10 to account for inter-individual variability, a guidance value of 150 (15) ng/m{sup 3} is derived for catalyst-borne platinum. The exposure to platinum in ambient air as measured or predicted is at least two orders of magnitude below this `critical` range. (orig.)

    Magnetic resonance imaging was performed in 22 male patients for localisation of 27 nonpalpable undescended testes. The operative verification, carried out in 19 testes (15 patients) served as basis for checking on the accuracy of MRI results and for their comparison with those of sonography and laparoscopy. The impalpable testis was localised via MRI in 13 cases and its lack was correctly established in three cases. There were three false MRI diagnoses. The suspicion of two intraabdominal localised testes were not confirmed at surgery and one intracanalicular testes were not seen by MRI. The low signal intensity of the undescended testes on T{sub 2}-weighted images is indicative for fibrotic changes and may be of value for more accurate planning of the operative volume. MRI offers a new promising opportunity for localisation and morphologic estimation of the undescended testis and should be performed before the invasive investigation methods. (orig.)

Der Verdacht auf zwei intraabdominal gelegene Hoden wurde operativ nicht bestaetigt, ein Leistenhoden mit MRT nicht gesehen. Die niedrige Signalintensitaet des undeszendierten Hodens auf dem T{sub 2}-gewichteten Bild erklaert sich durch fibrotische Veraenderungen und kann von Wert fuer die genauere Planung des Operationsausmasses sein.

    This final report for the Swiss Federal Office of Energy (SFOE) discusses the fundamentals for setting priorities on the use of hydropower and the protection of streams and rivers. New general conditions for the realisation of hydropower projects in Switzerland resulting from the cost-covering remuneration scheme for renewable energy sources have led to an increasing number of new projects. The article discussed the conflicts of interest between power station projects and environmental protectionists and anglers. A method is proposed that is to help resolve such conflicts. The development of the proposed methodology is discussed and the results of a test application of the methodology are examined. The report is enhanced with a comprehensive appendix.

    This report documents developments and results in the frame of the project RS1191 ''Development of computational methods for the safety assessment of gas-cooled high temperature and supercritical light-water reactors''. The report is structured according to the five work packages: 1. Reactor physics modeling of gas-cooled high temperature reactors; 2. Coupling of reactor physics and 3-D thermal hydraulics for the core barrel; 3. Extension of ATHLET models for application to supercritical reactors (HPLWR); 4. Further development of ATHLET for application to HTR; 5. Further development and validation of ANSYS CFX for application to alternative reactor concepts. Chapter 4 describes the extensions made in TORT-TD related to the simulation of pebble-bed HTR, e.g. spectral zone buckling, Iodine-Xenon dynamics, nuclear decay heat calculation and extension of the cross section interpolation algorithms to higher dimensions. For fast running scoping calculations, a time-dependent 3-D diffusion solver has been implemented in TORT-TD. For the PBMR-268 and PBMR-400 as well as for the HTR-10 reactor, appropriate TORT-TD models have been developed. Few-group nuclear cross sections have been generated using the spectral codes MICROX- 2 and DRAGON4. For verification and validation of nuclear cross sections and deterministic reactor models, MCNP models of reactor core and control rod of the HTR-10 have been developed. Comparisons with experimental data have been performed for the HTR-10 first criticality and control rod worth. The development of the coupled 3-D neutron kinetics and thermal hydraulics code system TORT-TD/ATTICA3D is documented in chapter 5. Similar to the couplings with ATHLET and COBRA-TF, the ''internal'' coupling approach has been implemented. Regarding the review of experiments and benchmarks relevant to HTR for validation of the coupled code system, the PBMR-400 benchmarks and the HTR-10 test reactor have been selected

    Financed by the German Environmental Agency a base of reference data has been generated, which is specifically suited to test and validate microscale flow and dispersion models. A fundamental concept for establishing a reference database has been developed and a set of basic requirements for validation data was defined. The laboratory standards and techniques applied in the boundary layer wind tunnel laboratory at Hamburg University were improved according to the higher quality standards required for generating laboratory data with reference quality. Extensive wind tunnel experiments have been carried out from which the fully documented validation data sets were compiled. All data generated within the scope of the project have been published on an Internet database enabling all potential users to have easy access to the reference data. Further data sets from existing wind tunnel experiments were quality checked and added to the data base. At present, the CEDVAL database, which is accessible under www.mi.uni-hamburg.de backslash cedval consists of 12 complete validation data sets. (orig.)

    Scientific research on animal husbandry in surface mining regions has started about a decade ago and preliminary results are now available. These regions include large surfaces, the future utilisation of which is still uncertain and which have a particular potential for nature protection. The project presented here analysed options for the utilisation and maintenance of the surface mining regions with a particular emphasis on domestic animals and game farming. The 600 sqkm mining region of Leipzig south (western Saxony) was chosen as a test region. The investigations were based on exhaustive bibliographic research, the analysis of statistical data and expert interviews. Animal husbandry can be part of a comprehensive concept for the ecological revitalisation of surface mining regions. They contain large areas with a high potential for nature protection which should be maintained and developed accordingly. Domestic animals can contribute to the management of nature protection sites on dumping areas by maintaining the vegetation at intermediate stages of succession where selected biotopes or species are to be conserved. Ruminants are important also for the management of reclaimed agricultural land which is used as grassland in order to preserve it for future agricultural use. Landscape management with herbivores is also an option for slopes of pits. The availability of sufficient feed is the limiting factor for animal husbandry on those areas and determines the pasturing systems to be chosen. (orig).

    For the demonstration of break preclusion for pressure retaining components in nuclear power plants, the nuclear safety standard KTA 3206 determines also the requirements for the leak-before-break verification. For this procedure, it has to be ensured that a wall-penetrating crack is subcritical with respect to instable growth, and that the resulting leakage under stationary operation conditions can be detected by a leak detection system. Within the scope of the project 3613R01332 analyses with respect to conservative estimates of the leak rates in case of detections regarding break preclusion were performed by means of leak rate models being available at GRS. For this purpose, conservative assumptions in the procedure were quantified by comparative calculations concerning selected leak rate experiments and the requirements regarding the determination of leak rates indicated in the KTA 3206 were verified and specified. Moreover, the models were extended and relevant recommendations for the calculation procedure were developed. During the investigations of leak rate tests the calculation methods were validated, qualified by means of both examples indicated in KTA 3206 and applied to a postulated leak accident in the cooling circuit of a PWR. For the calculation of leak rates several simplified solution methods which are included in the GRS program WinLeck were applied, and for the simulation of a leak accident the large-scale programs ANSYS Mechanical and ATHLET (thermohydraulics program developed by GRS) were used. When applying simplified methods for the calculation of leak rates using the limiting curve for the friction factor which has been derived during the project and which is included in the KTA 3206 attention has to be paid to the fact that in case of small flow lengths the entrance loss can dominate compared to the friction loss. However, the available data do not suffice in order to make a quantitative statement with respect to limits of applicability

    Weldments have been a major topic of engineering fracture mechanics research for many years as it shows up in the immense number of scientific papers published recently. Part of this generated knowledge has already been implemented in some industrial codes and standards. The focussing on weldments has its own reason in the utmost importance of this class of components in many industrial fields, but also in its susceptibility to the formation of defects during manufacturing and cracks in service, which promotes the danger of component failure. The present report is addressed to designers and material testers to provide updated information on the present state-of-the-art of fracture mechanics application to weldments. (orig.) [German] Schweissverbindungen bilden seit vielen Jahren einen Schwerpunkt der anwendungsnahen bruchmechanischen Forschung, was seinen Niederschlag in einer nahezu unuebersehbaren Fuelle an wissenschaftlichen Publikationen findet. Ein Teil der Ergebnisse hat bereits Eingang in industrienahe bruchmechanische Bewertungsvorschriften gefunden. Die Konzentration auf Schweissverbindungen hat ihre Ursache in der immensen Bedeutung dieser Bauteilklasse fuer viele Gebiete der Volkswirtschaft, aber auch in ihrer besonderen Anfaelligkeit zur Rissbildung in der Fertigung und im Betrieb und damit hinsichtlich der Gefahr von Bauteilversagen. Der vorliegende Beitrag wendet sich an Konstrukteure und Werkstoffpruefer, die einen Einblick in den gegenwaertigen Stand der Ingenieurbruchmechanik an Schweissverbindungen gewinnen wollen. (orig.)

    The preservation of buildings is increasingly becoming the focus of public attention, not least because of traffic restrictions on roads and bridges, which have grown significantly in recent years. Here the building inspectors is of particular importance to assess the causes and extent of repair work as required. This non-destructive testing in the construction industry (ZfPBau method) have become indispensable. However, very few rules are found in construction in contrast to the classical industrial NDT. Also the offers to the qualification of examiners are low, but but in the meantime available. The symposium takes this conflict area to less regulation and a high demand of professional services. One of tasks of the future is the reliable evaluation of existing structures. The foundation was laid by the adoption of the directive for the recalculation of road bridges in 2011 to have results of non-destructive examination incorporated in recalculations. Meanwhile are first experiences on investigations and recalculations of bridges that will be presented at the symposium for the first time. [German] Die Erhaltung von Bauwerken rueckt immer mehr in den Fokus der Oeffentlichkeit, nicht zuletzt durch Verkehrseinschraenkungen an Strassen und Bruecken, die in den letzten Jahren spuerbar zugenommen haben. Dabei kommt den Bauwerkspruefern eine besondere Bedeutung zu, Ursachen und Umfang von Instandsetzungsmassnahmen bedarfsgemaess abzuschaetzen. Hierbei sind zerstoerungsfreie Pruefverfahren im Bauwesen (ZfPBau-Verfahren) nicht mehr wegzudenken. Allerdings sind im Gegensatz zur klassischen industriellen ZfP im Bauwesen sehr wenige Regelwerke anzutreffen. Auch die Angebote zur Qualifizierung von Pruefern sind gering aber mittlerweile vorhanden. Die Fachtagung greift dieses Spannungsfeld geringer Regelsetzung und grossem Bedarf qualifizierter Dienstleistungen auf. Ein Aufgabenfeld der Zukunft ist die zuverlaessige Bewertung von Bestandsbauwerken. Durch das Inkrafttreten der

This paper explores the concept of test quality and its relationship with operational readiness and preventive maintenance. This paper also considers the frequencies of component testing. Test quality is related to a test's ability to detect degradation that can cause component failure. The quality of the test depends on several factors, including specific parameters measured, system or component conditions, and instrument accuracy. The quality of some currently required tests for check valves, motor-operated valves, and pumps is also discussed. Suggestions are made to improve test quality by measuring different parameters, testing valves under load, and testing positive displacement pumps at high pressure and centrifugal pumps at high flow rate conditions. These suggestions can help to improve the level of assurance of component operational readiness gained from testing

    The research project serves the only purpose of preparation of a detailed research proposal for the topic 'River Basin Management' in the research focus (BMBF) 'Research for the Environment'. The report contain those contents of the research proposal which are of basic interest and general validity. Furthermore the various aspects of its production are presented. The topics and problems dealt with in the research proposal are as follows: The Europen Union requires that water management in future should be handled in the sense of integrated river basin management. Thus one of the main objectives of the intended research project is the development of methods and instruments suitable for integrated river basin management, which presently hardly exist. This requires on the one hand development of theories, on the other hand their validation along with a real river system. For this purpose the basin of the Lippe river was chosen. River basin management requires the introduction of several measures suitable to change the present conditions of water quality in rivers and groundwater towards the conditions which are required by the framework directive. This, in turn, requires a multidimensional evaluation of those measures as far as ecology, technical efficiency and social economy are concerned. The decision support system to be developed shall aggregate those evaluated measures into few parameters relevant for decision making. This way it will be feasible for the decision makers to decide between prepared alternatives in a transparent way. It is expected that the project will lead to economically improved solutions and form the basis for future research. (orig.)

Der Bericht enthaelt die wesentlichen grundsaetzlich interessanten und allgemein gueltigen Inhalte des Forschungsantrags sowie die Begleitumstaende seiner Erstellung. Thematisch geht es hierbei um die nachfolgend dargestellte Problemstellung. Wasserwirtschaft soll kuenftig im Sinne der EU als integriertes Flusseinzugsgebietsmanagement betrieben weren. Das hierfuer erforderliche - derzeit kaum vorhandene - methodische Instrumentarium zu entwickeln, ist Hauptziel des Forschungsvorhabens. Dies bedingt zum einen Theorieentwicklung, zum anderen deren Validierung an einem realen Flusssystem, wofuer hier das Lippe-Einzugsgebiet gewaehlt wurde. Flusseinzugsgebietsmanagement beinhaltet die Durchfuehrung von zahlreichen Massnahmen, die den derzeitigen Zustand in Hinblick auf die Wasserqualitaet in den Gewaessern den gewuenschten Zielzustaenden annaehert. Hierzu muessen vorgesehene Massnahmen zunaechst mehrdimensional bewertet werden (oekologisch, technisch, sozio-oekonomisch). Ein zu entwickelndes Entscheidungsunterstuetzungs-System soll diese bewerteten Massnahmenbuendel zu wenigen entscheidungsrelevanten Parametern aggregieren, wodurch den Entscheidungstraegern die Wahl ihrer praeferierten Alternative in transparenter Weise ermoeglicht wird. Das Projekt wird zu oekonomisch besseren Loesungen fuehren und Basis fuer weitergehende Forschungen sein koennen. (orig.)

    Persistente and highly toxic sewages with an extremely high content of substances are still a problem in the waste water management. Wet oxidation offers a possibility to reduce the pollutant content in the water. Comparative experiments of the efficiency of oxidation initiated by radicals were carried out, using as heterogeneous catalysis on strap catalyst base as cavitation. By means of the wet oxidation on strap catalyst base with H{sub 2}O{sub 2} as oxidation reagent it was possible, to decontaminate effectively as single pollutants in model sewages as complex substance mixtures in real sewages. The tested catalytic systems worked especially effectively for high pollutant concentrations. At lower concentrations of sewage pollutants the amount of H{sub 2}O{sub 2} must be increased in regard to the actual CSB. In real sewages the pollutant decrease was, related on the TOC, in the cut, at 50%, a raise of the average concentration of the oxidation agent didn't produce any further decrease of the pollutant concentration. Aromatic hydrocarbons could be reduced more effectively than aliphatic ones. The conception for a technical plant was developed including cost estimate. The reduction of pollutants by cavitation was fundamentally lower than by using the heterogeneous catalysis way. Without addition of an oxidation agent (i.e. H{sub 2}O{sub 2}) only a TOC decrease of approx. 15% was registered in real sewages. The pollutant reduction increased at higher pollutant concentration. A complete elimination of all pollutants could not be obtained in none of the examined cases neither at model nor at real sewages. Especially the long reaction times (6 to 24 h) of the cavitation process in comparison with those, necessary for the catalytic reaction (2 to 6 h) are hindering a technical realization of the cavitation process, which seems to be doubtful for this and other reasons. So the use of cavitation in industrial scale sewage cleaning plants under the parameter

    This comprehensive report for the Swiss Federal Office of Energy (SFOE) deals with the evaluation of a system for the disposal and use of biogenic wastes and farm dung. The principle aim of the study was to develop a method for the evaluation of the various methods for the disposal and use of biogenic wastes and the manure produced in agriculture. A further aim was the exemplary use of the method on a selection of waste disposal methods and the drawing of initial conclusions from the ecological, economic and social points of view. The report provides details on the biomass fractions examined and their energy content. The fundamentals on which the development of the methods used are based are described. Test use of the multi-criterion analysis developed is discussed as is sensitivity analysis. Finally conclusions concerning the evaluation are presented and recommendations are made. The appendix to the report contains details on the comprehensive questionnaire used to collect information and the results of an on-line survey on the weighting of the criteria. Also, fact sheets on the 24 disposal and usage variants examined and an overview of disposal and collection costs are presented. The appendix also contains result tables on the use of the method for biogenic wastes, sewage sludge, farm manure, wood wastes and scrap wood.

    1985-01-01

    In the 1950s, most of the men who witnessed Britain's nuclear tests at Christmas Island in the Pacific were national servicemen, aged 19 or 20. Some revelled in sun and swimming, some were bored, some were too busy to be bored. How many of the twenty thousand servicemen involved in the tests suspected that they might be exposed to radiation that would reveal itself a generation later in blood and bone cancers, sterility, cataracts, or deformities in their children. The Ministry of Defence insists nobody was in danger. This book tells a different story, in the words of the servicemen, and of their medical reports, about secrets which are no longer Official. It is important not only to the victims of a government's extraordinary reluctance to face up to the tragic consequences of a programme of nuclear tests on Christmas Island and in Australia, but to anyone concerned with the damage that nuclear testing is still doing in the world today.

    Full Text Available Since the amendment of the German Renewable Energy Act (EEG in 2012 as well as in the current version (EEG 2014 the parameters for the expansion of renewable energies aim for a stronger market integration of those. Thereby, biogas plants represent a promising option to produce demand-driven energy to compensate differences between energy demand and energy supply caused by irregular sources (e. g. wind and solar. The contribution focuses on the economic assessment of the flexible biogas production by specific feeding in comparison to continuous gas production against the background of a flexible conversion of biogas into electrical power. The required additional demand for gas storage capacity of a model biogas plant is determined by combinations of different feeding regimes and by three optimised power generation schedules. Subsequently, a cost-benefit analysis is conducted to assess the substrate management economically. The developed methodology is especially designed for existing plants and is used for assessing a multi-factorial substrate management as flexibility option. The results show that substrate management is increasingly appropriate to reduce the additional demand for gas storage especially for longer-term planning horizons (above 12 h regarding schedule organisation. Moreover, the flexible operation allows generating higher marketing revenues on the European Power Exchange (EPEX Spot SE at low additional costs.

    The dry exhaust gas cleaning uses sodium bicarbonate in order to absorb acid components of exhaust gases such as sulphur dioxide or hydrochloric acid. Recently, sodium and calcium based adsorbents are compared with respect to their economic and ecologic options. None of the investigations performed considered decidedly practical experiences from the system operation such as differences in the management, availability, personnel expenditure and maintenance expenditure. Under this aspect, the authors of the contribution under consideration report on exhaust gas cleaning systems using sodium carbonate as well as lime adsorbents. The operators of these exhaust gas cleaning systems were questioned on their experiences, and all relevant operational data (consumption of additives, consumption of energy, emissions, standstill, maintenance effort) were recorded and evaluated at a very detailed level.

By way of simplified examples, we illustrate some dangers in blind statistical assessments, pointing out especially the need to include theoretical uncertainties, the danger of over-weighting precise or physically redundant experimental results, the need to assess competing theories with independent and physically sensitive observables, and the value of statistical tests properly evaluated.

    The groundbreaking book Design Driven Testing brings sanity back to the software development process by flipping around the concept of Test Driven Development (TDD) - restoring the concept of using testing to verify a design instead of pretending that unit tests are a replacement for design. Anyone who feels that TDD is "Too Damn Difficult" will appreciate this book. Design Driven Testing shows that, by combining a forward-thinking development process with cutting-edge automation, testing can be a finely targeted, business-driven, rewarding effort. In other words, you'll learn how to test

    2012-01-01

    Background: Student's two-sample t test is generally used for comparing the means of two independent samples, for example, two treatment arms. Under the null hypothesis, the t test assumes that the two samples arise from the same normally distributed population with unknown variance. Adequate...... control of the Type I error requires that the normality assumption holds, which is often examined by means of a preliminary Shapiro-Wilk test. The following two-stage procedure is widely accepted: If the preliminary test for normality is not significant, the t test is used; if the preliminary test rejects...... the null hypothesis of normality, a nonparametric test is applied in the main analysis. Methods: Equally sized samples were drawn from exponential, uniform, and normal distributions. The two-sample t test was conducted if either both samples (Strategy I) or the collapsed set of residuals from both samples...

  14. Vendor System Vulnerability Testing Test Plan

    Energy Technology Data Exchange (ETDEWEB)

    James R. Davidson

    2005-01-01

    The Idaho National Laboratory (INL) prepared this generic test plan to provide clients (vendors, end users, program sponsors, etc.) with a sense of the scope and depth of vulnerability testing performed at the INL’s Supervisory Control and Data Acquisition (SCADA) Test Bed and to serve as an example of such a plan. Although this test plan specifically addresses vulnerability testing of systems applied to the energy sector (electric/power transmission and distribution and oil and gas systems), it is generic enough to be applied to control systems used in other critical infrastructures such as the transportation sector, water/waste water sector, or hazardous chemical production facilities. The SCADA Test Bed is established at the INL as a testing environment to evaluate the security vulnerabilities of SCADA systems, energy management systems (EMS), and distributed control systems. It now supports multiple programs sponsored by the U.S. Department of Energy, the U.S. Department of Homeland Security, other government agencies, and private sector clients. This particular test plan applies to testing conducted on a SCADA/EMS provided by a vendor. Before performing detailed vulnerability testing of a SCADA/EMS, an as delivered baseline examination of the system is conducted, to establish a starting point for all-subsequent testing. The series of baseline tests document factory delivered defaults, system configuration, and potential configuration changes to aid in the development of a security plan for in depth vulnerability testing. The baseline test document is provided to the System Provider,a who evaluates the baseline report and provides recommendations to the system configuration to enhance the security profile of the baseline system. Vulnerability testing is then conducted at the SCADA Test Bed, which provides an in-depth security analysis of the Vendor’s system.b a. The term System Provider replaces the name of the company/organization providing the system

  16. Tractor accelerated test on test rig

    Directory of Open Access Journals (Sweden)

    M. Mattetti

    2013-09-01

    Full Text Available The experimental tests performed to validate a tractor prototype before its production, need a substantial financial and time commitment. The tests could be reduced using accelerated tests able to reproduce on the structural part of the tractor, the same damage produced on the tractor during real life in a reduced time. These tests were usually performed reproducing a particular harsh condition a defined number of times, as for example using a bumpy road on track to carry out the test in any weather condition. Using these procedures the loads applied on the tractor structure are different with respect to those obtained during the real use, with the risk to apply loads hard to find in reality. Recently it has been demonstrated how, using the methodologies designed for cars, it is possible to also expedite the structural tests for tractors. In particular, automotive proving grounds were recently successfully used with tractors to perform accelerated structural tests able to reproduce the real use of the machine with an acceleration factor higher than that obtained with the traditional methods. However, the acceleration factor obtained with a tractor on proving grounds is in any case reduced due to the reduced speed of the tractors with respect to cars. In this context, the goal of the paper is to show the development of a methodology to perform an accelerated structural test on a medium power tractor using a 4 post test rig. In particular, several proving ground testing conditions have been performed to measure the loads on the tractor. The loads obtained were then edited to remove the not damaging portion of signals, and finally the loads obtained were reproduced in a 4 post test rig. The methodology proposed could be a valid alternative to the use of a proving ground to reproduce accelerated structural tests on tractors.

  1. Ecological assessment of agricultural co-substrates for biogas production; Oekologische Bewertung der Bereitstellung landwirtschaftlicher Kosubstrate zur Biogaserzeugung

    2002-07-01

    This paper presents the results of simplified life cycle assessments (LCA) of the cultivation of a variety of crops suitable for biogas production. The simplification refers to that only greenhouse gases and the cumulated energy requirements (CER) are regarded. The values for the greenhouse gas emissions expressed as CO{sub 2} equivalents are around 130 g CO{sub 2}eq.kg{sup -1} ODM with lowest value of 75.5 g CO{sub 2}eq.kg{sup -1} ODM for hemp (Cannabis sativa) and the highest value of 170 g CO{sub 2}eq.kg{sup -1} ODM for rape (Brassica napus). Considering electric power as final product and referring therefore on kWh as unit the differences become even greater, mainly because of the different methane production potentials. On this basis the lowest value amounts to 84 g CO{sub 2}eq.kWh{sup -1} for alfalfa (Medicago sativa) and the highest value amounts to 438 g CO{sub 2}eq.kWh{sup -1} for rape. This general trend that the LCA identifies hemp, forage grass (Dactylis, Lolium and Festuca species), alfalfa, and maize (Zea mays) to have a low ecologic input and rape to have a high ecologic input is confirmed regarding the CER. The CER values are lowest with 0.82 MJ.kWh{sup -1} for maize and forage grass and highest with 3.47 MJ.kWh{sup -1} for rape. (orig.)

    More and more often, plannings require climate statements which are suitable to be considered in the weighing of the different factors. The paper makes climate assessment proposals permitting a qualitative and quantitative judgement. Parameters employed are the physiologically equivalent temperature (PET) as well as, increasingly, statements regarding the quality of ventilation. Examples illustrate how space-related planning clues can be derived from climate function maps. The basis for this are climate-geographic surveys (orohydrographic analysis, topographic gradient determination etc.), as well as the analysis of dynamic parameters (air conduction paths and barriers) and thermal parameters (areas warming up excessively, areas of cold and fresh air generation). Linking of these aspects yields a climate function map. It is used to prepare a planning recommendations map which differentiates and evaluates climate-ecological sensitivities. (orig.) [Deutsch] Im Rahmen von Planungsprozessen werden immer haeufiger Klimaaussagen verlangt, die in die Planungsabwaegung Eingang finden koennen. Dazu werden Klimabewertungsvorschlaege fuer eine qualitative und quantitative Beurteilung gemacht. Anwendung finden die bioklimatischen Komplexgroessen und vermehrt Aussagen zur Belueftungsqualitaet. Beispiele verdeutlichen, wie sich aus den Klimafunktionskarten raeumliche Planungshinweise ableiten lassen. Grundlage sind klimageographische Erhebungen (orohydrographische Analyse, topographische Gradientenbestimmung usw.) sowie die Analyse der dynamischen (Luftleitbahnen und Barrieren) und thermischen Parameter (Ueberwaermungsgebiete, Kalt- und Frischluftentstehungsgebiete). In einer Verknuepfung dieser Aspekte wird die Klimafunktionskarte erstellt, aus der die Planungshinweiskarte abgeleitet wird, die klimaoekologische Empfindlichkeiten differenziert und bewertet.

    This final report for the Swiss Federal Office of Energy (SFOE) deals with the results of a study that evaluated the environmental impact of the entire production chain of fuels made from biomass and used in Switzerland. Firstly, the study supplies an analysis of the possible environmental impacts of biofuels that can be used as a basis for political decisions. Secondly, an environmental life cycle assessment (LCA) of various biofuels is presented. In addition, the impacts of fuel use are compared with other uses for bioenergy such as the generation of electricity and heat. The methods used in the LCA are discussed, including the Swiss method of ecological scarcity (Environmental Impact Points, UBP 06), and the European Eco-indicator 99 method. The results of the study are discussed, including the finding that not all biofuels can reduce environmental impacts as compared to fossil fuels. The role to be played by biofuels produced in an environmentally-friendly way together with other forms of renewable energy in our future energy supply is discussed.

    Most concepts for charging of electric vehicles are based on cables that must be plugged in and out. In case of frequent charging or short-term charging, however, this may be impractical, and an inductive (cableless) solution would be preferable. The contribution attempts to analyze if inductive power transmission is technically feasible in electric vehicles, and in what areas it will be economically attractive to users. To begin with, the two charging technologies are presented and compared. This is followed by a cost assessment. It is found that the inductive technology involves significant additional cost, so it cannot be expected to spread quickly. In certain conditions, however, it may be applicable as a niche technology in certain commercial applications, e.g. taxis. (orig.) [German] In den bisher diskutierten Konzepten zur Ladung von Elektrofahrzeugen ist die kabelgebundene (konduktive) Ladung vorherrschend, bei der der Nutzer das Kabel zur Ladung ein- bzw. wieder ausstecken muss. Haeufige Ladevorgaenge und insbesondere Kurzladungen lassen jedoch dieses Ein- und Ausstecken neben der reduzierten Reichweite des Elektrofahrzeugs unpraktisch in der Nutzung erscheinen. Demgegenueber bietet die induktive (kabellose) Energieuebertragung das Laden ohne erforderlichen Nutzereingriff. Der vorliegende Artikel versucht die Fragen zu beantworten, ob ein Einsatz der induktiven Energieuebertragung bereits technisch zur Ladung von Elektrofahrzeugen realisierbar ist, und in welchen Bereichen diese eine wirtschaftlich attraktive Loesung fuer den Nutzer darstellt. Dazu werden zunaechst die Ladetechnologien vor- und technisch gegenuebergestellt. Auf Basis einer Kostenbetrachtung ist auch ein oekonomischer Vergleich der beiden Ladetechnologien moeglich. Es zeigt sich, dass aus wirtschaftlicher Sicht aufgrund signifikanter Mehrkosten vorlaeufig kein weitverbreiteter Einsatz der induktiven Technik zu erwarten ist. Unter bestimmten Voraussetzungen ergibt sich aber ein begrenztes Anwendungsfeld als Nischentechnologie in bestimmten gewerblichen Bereichen, wie zum Beispiel bei Taxis.

  7. Evaluation and optimization of goal strategies for solar tower power plants; Bewertung und Optimierung von Zielpunktstrategien fuer solare Turmkraftwerke

    Energy Technology Data Exchange (ETDEWEB)

    Belhomme, Boris

    2011-07-01

    The levelized costs of a solar tower power plant are mainly influenced by the operational strategy of its heliostat field. Ensuring an efficient utilization of the heliostat field during the plant operation and therewith a high overall efficiency requires an optimal aim point strategy. The objective of the present work is to develop a computer-aided method for the optimization of aim point strategies. One main prerequisite for this kind of optimization is a realistic evaluation of a given aim point configuration. For this purpose an efficient ray tracing model for a fast and precise calculation of the flux density distribution caused by heliostats is developed as a first step. It is validated by a comparison of simulated and measured flux density distributions. By coupling the ray tracing model and a physical model of a receiver any variable of the receiver model can act as optimization variable. In a second step a method for the optimization of aim point configurations is developed. By defining a finite number of fixed aims points, the present problems becomes a combinatorial optimization problem. Due to the problem complexity, an exact solution can usually not be determined. On the other hand, this allows applying algorithms for the global optimization of combinatorial problems. Accordingly the Ant Colony Optimization metaheuristic is applied and adapted to the aim point optimization problem. By means of two selected example cases the general suitability of the method for the purpose of aim point optimization is proved and the influence of different optimization parameters on the optimization process is investigated.

    Full Text Available Der Bekämpfungserfolg beim Einsatz thermisch arbeitender Unkrautbekämpfungsgeräte kann in der Praxis starken Schwankungen unterliegen. Als Ursache wird vermutet, dass die Temperaturverteilung im Arbeitsbereich solcher Geräte nicht homogen ist, was bislang aufgrund fehlender Daten nicht nachgewiesen werden konnte. Um diese Hypothese zu belegen, wurde eine Methode zur systematischen Überprüfung von handgeschobenen Geräten für die thermische Unkrautbekämpfung entwickelt. Prüfkriterium ist die Verteilung der Temperaturverläufe im Arbeitsbereich der Geräte bei unterschiedlichen Arbeitsgeschwindigkeiten. Es konnte gezeigt werden, dass die Temperatur von der Arbeitsgeschwindigkeit abhängig ist und dass heterogene Temperaturverteilungen sehr gut nachgewiesen werden können.

    The investigation focused on controlled hydrological storage system. Existing operating schedules and new control options were analyzed, classified and generalized in order to obtain a standardized terminology and operating concept. This generalized approach will do away with the need for system-specific analyses and models for every single new system. [German] Der Schwerpunkt dieser Arbeit ist der wasserwirtschaftliche Betrieb von regelbaren Speichersystemen und ihre Simulation. Dabei bestand das Ziel darin, bestehende Betriebsplaene und neue praktikable Steuerungsmoeglichkeiten zu analysieren, zu klassifizieren und so zu generalisieren, dass eine einheitliche Terminologie und Konzeption zum Betrieb von Speichern entstand. Dieses Konzept erlaubt, in Verbindung mit den Prinzipien aus der Modellierung von Flussgebieten, verschieden strukturierte Speichersysteme mit unterschiedlichsten Steuerungsvorschriften abzubilden. Damit erhaelt man den Vorteil einer generalisierten Anwendung im Gegensatz zu einer fuer den speziellen Fall konzipierten und nicht uebertragbaren Einzelloesung. Als Folge davon entfaellt das systemspezifische, je nach Aufgabenstellung neu zu entwerfende und zu programmierende Einzelmodell. (orig.)

    The desire and ability to fly Unmanned Aircraft Systems (UAS) in the National Airspace System (NAS) is of increasing urgency. The application of unmanned aircraft to perform national security, defense, scientific, and emergency management are driving the critical need for less restrictive access by UAS to the NAS. UAS represent a new capability that will provide a variety of services in the government (public) and commercial (civil) aviation sectors. The growth of this potential industry has not yet been realized due to the lack of a common understanding of what is required to safely operate UAS in the NAS. NASA's UAS Integration into the NAS Project is conducting research in the areas of Separation Assurance/Sense and Avoid Interoperability, Human Systems Integration (HSI), and Communication to support reducing the barriers of UAS access to the NAS. This research is broken into two research themes namely, UAS Integration and Test Infrastructure. UAS Integration focuses on airspace integration procedures and performance standards to enable UAS integration in the air transportation system, covering Sense and Avoid (SAA) performance standards, command and control performance standards, and human systems integration. The focus of Test Infrastructure is to enable development and validation of airspace integration procedures and performance standards, including the integrated test and evaluation. In support of the integrated test and evaluation efforts, the Project will develop an adaptable, scalable, and schedulable relevant test environment capable of evaluating concepts and technologies for unmanned aircraft systems to safely operate in the NAS. To accomplish this task, the Project will conduct a series of Human-in-the-Loop and Flight Test activities that integrate key concepts, technologies and/or procedures in a relevant air traffic environment. Each of the integrated events will build on the technical achievements, fidelity and complexity of the previous tests and

    The objective of the Digface Characterization (DFC) Remote Testing project is to remotely deploy a sensor head (Mini-Lab) across a digface to determine if it can characterize the contents below the surface. The purpose of this project is to provide a robotics technology that allows removal of workers from hazards, increases speed of operations, and reduces life cycle costs compared to alternate methods and technologies. The Buried Waste Integrated Demonstration (BWID) is funding the demonstration, testing, and evaluation of DFC. This document describes the test plan for the DFC remote deployment demonstration for the BWID. The purposes of the test plan are to establish test parameters so that the demonstration results are deemed useful and usable and perform the demonstration in a safe manner and within all regulatory requirements

    This document is a flight test report from the Operational perspective for Flight Test Series 3, a subpart of the Unmanned Aircraft System (UAS) Integration in the National Airspace System (NAS) project. Flight Test Series 3 testing began on June 15, 2015, and concluded on August 12, 2015. Participants included NASA Ames Research Center, NASA Armstrong Flight Research Center, NASA Glenn Research Center, NASA Langley Research center, General Atomics Aeronautical Systems, Inc., and Honeywell. Key stakeholders analyzed their System Under Test (SUT) in two distinct configurations. Configuration 1, known as Pairwise Encounters, was subdivided into two parts: 1a, involving a low-speed UAS ownship and intruder(s), and 1b, involving a high-speed surrogate ownship and intruder. Configuration 2, known as Full Mission, involved a surrogate ownship, live intruder(s), and integrated virtual traffic. Table 1 is a summary of flights for each configuration, with data collection flights highlighted in green. Section 2 and 3 of this report give an in-depth description of the flight test period, aircraft involved, flight crew, and mission team. Overall, Flight Test 3 gathered excellent data for each SUT. We attribute this successful outcome in large part from the experience that was acquired from the ACAS Xu SS flight test flown in December 2014. Configuration 1 was a tremendous success, thanks to the training, member participation, integration/testing, and in-depth analysis of the flight points. Although Configuration 2 flights were cancelled after 3 data collection flights due to various problems, the lessons learned from this will help the UAS in the NAS project move forward successfully in future flight phases.

    1989-01-01

    The testing stages in NET for the performance assessment of the various breeding blanket concepts developed at the present time in Europe for DEMO (LiPb and ceramic blankets) and the requirements upon NET to perform these tests are reviewed. Typical locations available in NET for blanket testing are the central outboard segments and the horizontal ports of in-vessel sectors. These test positions will be connectable with external test loops. The number of test loops (helium, water, liquid metal) will be such that each major class of blankets can be tested in NET. The test positions, the boundary conditions and the external test loops are identified and the requirements for test blankets are summarized (author). 6

  15. Pancreatic exocrine function testing

    International Nuclear Information System (INIS)

    Goff, J.S.

    1981-01-01

    It is important to understand which pancreatic function tests are available and how to interpret them when evaluating patients with malabsorption. Available direct tests are the secretin stimulation test, the Lundh test meal, and measurement of serum or fecal enzymes. Indirect tests assess pancreatic exocrine function by measuring the effect of pancreatic secretion on various nutrients. These include triglycerides labeled with carbon 14, cobalamin labeled with cobalt 57 and cobalt 58, and para-aminobenzoic acid bound to a dipeptide. Of all these tests the secretin stimulation test is the most accurate and reliable if done by experienced personnel. However, the indirect tests are simpler to do and appear to be comparable to the secretin test at detecting pancreatic exocrine insufficiency. These indirect tests are becoming clinically available and clinicians should familiarize themselves with the strengths and weaknesses of each

  17. The hardness test: a real mechanical test

    Rezakhanlou, R.

    1993-02-01

    During the service life, the mechanical properties of the PWR components change. It is necessary to determine precisely this evolution, but it is not always possible to draw a sample with the adequate size for the characterization. For this latter case we intend to calculate the stress-strain curve of a material from a hardness test results, because it is appropriate for testing on site and do not need any particular sample shape. This paper is the first bibliographical part of a larger study on the relation between the values measured during a hardness test (applied load, indentation diameter) and the mechanical properties of a solid obtained by a traction test. We have treated the problem within the general setting of two solids in contact. Thus, we expose general elastic, elasto-plastic and plastic models describing the indentation of a solid by a rigid indenter

O teste de vasorreatividade pulmonar é indicado para definir a melhor opção terapêutica. Muitas drogas têm sido utilizadas para a realização desse teste, sendo o óxido nítrico inalado a melhor opção, por apresentar ação específica pulmonar e meia vida muita curta (5-10 s. O resultado desse teste identifica candidatos à cirurgia cardíaca nas cardiopatias congênitas e candidatos ao uso de antagonista de cálcio nas outras formas de hipertensão pulmonar. A realização e interpretação do teste de vasorreatividade pulmonar exigem grande responsabilidade, e erros podem levar a decisões erradas e à ocorrência de óbitos.Pulmonary arterial hypertension is classified as idiopathic or secondary (associated with collagenoses, heart disease, portal hypertension, pulmonary thromboembolism, and pulmonary vascular diseases. Pulmonary vasoreactivity should be tested in order to define the best treatment option. Of the many drugs that have been used to test pulmonary vasoreactivity, inhaled nitric oxide is the best choice, due its specific pulmonary effect and very short half-life (5-10 s. The results of this test identify candidates for heart surgery among patients with congenital heart disease and candidates for the use of calcium antagonists among patients with other forms of pulmonary hypertension. Performing and interpreting the results of such tests are a great responsibility, since mistakes can lead to incorrect treatment decisions, resulting in the death of patients.

  20. TESTING TESTS ON ACTIVE GALACTIC NUCLEI MICROVARIABILITY

    International Nuclear Information System (INIS)

    De Diego, Jose A.

    2010-01-01

    Literature on optical and infrared microvariability in active galactic nuclei (AGNs) reflects a diversity of statistical tests and strategies to detect tiny variations in the light curves of these sources. Comparison between the results obtained using different methodologies is difficult, and the pros and cons of each statistical method are often badly understood or even ignored. Even worse, improperly tested methodologies are becoming more and more common, and biased results may be misleading with regard to the origin of the AGN microvariability. This paper intends to point future research on AGN microvariability toward the use of powerful and well-tested statistical methodologies, providing a reference for choosing the best strategy to obtain unbiased results. Light curves monitoring has been simulated for quasars and for reference and comparison stars. Changes for the quasar light curves include both Gaussian fluctuations and linear variations. Simulated light curves have been analyzed using χ 2 tests, F tests for variances, one-way analyses of variance and C-statistics. Statistical Type I and Type II errors, which indicate the robustness and the power of the tests, have been obtained in each case. One-way analyses of variance and χ 2 prove to be powerful and robust estimators for microvariations, while the C-statistic is not a reliable methodology and its use should be avoided.

  3. From optics testing to micro optics testing

    Science.gov (United States)

    Brock, Christian; Dorn, Ralf; Pfund, Johannes

    2017-10-01

    Testing micro optics, i.e. lenses with dimensions down to 0.1mm and less, with high precision requires a dedicated design of the testing device, taking into account propagation and wave-optical effects. In this paper, we discuss testing methods based on Shack-Hartmann wavefront technology for functional testing in transmission and for the measurement of surface shape in reflection. As a first example of more conventional optics testing, i.e. optics in the millimeter range, we present the measurement of binoculars in transmission, and discuss the measured wave aberrations and imaging quality. By repeating the measurement at different wavelengths, information on chromatic effects is retrieved. A task that is often tackled using Shack-Hartman wavefront sensors is the alignment of collimation optics in front of a light source. In case of a micro-optical collimation unit with a 1/e² beam diameter of ca. 1mm, we need adapted relay optics for suitable beam expansion and well-defined imaging conditions. In this example, we will discuss the alignment process and effects of the relay optics magnification, as well as typical performance data. Oftentimes, micro optics are fabricated not as single pieces, but as mass optics, e.g. by lithographic processes. Thus, in order to reduce tooling and alignment time, an automated test procedure is necessary. We present an approach for the automated testing of wafer- or tray-based micro optics, and discuss transmission and reflection measurement capabilities. Exemplary performance data is shown for a sample type with 30 microns in diameter, where typical repeatabilities of a few nanometers (rms) are reached.

  4. Gas Test Loop Booster Fuel Hydraulic Testing

    Energy Technology Data Exchange (ETDEWEB)

    Gas Test Loop Hydraulic Testing Staff

    2006-09-01

    The Gas Test Loop (GTL) project is for the design of an adaptation to the Advanced Test Reactor (ATR) to create a fast-flux test space where fuels and materials for advanced reactor concepts can undergo irradiation testing. Incident to that design, it was found necessary to make use of special booster fuel to enhance the neutron flux in the reactor lobe in which the Gas Test Loop will be installed. Because the booster fuel is of a different composition and configuration from standard ATR fuel, it is necessary to qualify the booster fuel for use in the ATR. Part of that qualification is the determination that required thermal hydraulic criteria will be met under routine operation and under selected accident scenarios. The Hydraulic Testing task in the GTL project facilitates that determination by measuring flow coefficients (pressure drops) over various regions of the booster fuel over a range of primary coolant flow rates. A high-fidelity model of the NW lobe of the ATR with associated flow baffle, in-pile-tube, and below-core flow channels was designed, constructed and located in the Idaho State University Thermal Fluids Laboratory. A circulation loop was designed and constructed by the university to provide reactor-relevant water flow rates to the test system. Models of the four booster fuel elements required for GTL operation were fabricated from aluminum (no uranium or means of heating) and placed in the flow channel. One of these was instrumented with Pitot tubes to measure flow velocities in the channels between the three booster fuel plates and between the innermost and outermost plates and the side walls of the flow annulus. Flow coefficients in the range of 4 to 6.5 were determined from the measurements made for the upper and middle parts of the booster fuel elements. The flow coefficient for the lower end of the booster fuel and the sub-core flow channel was lower at 2.3.

    2016-06-01

    Testing is a major approach for the detection of software defects, including vulnerabilities in security features. This article introduces metamorphic testing (MT), a relatively new testing method, and discusses how the new perspective of MT can help to conduct negative testing as well as to alleviate the oracle problem in the testing of security-related functionality and behavior. As demonstrated by the effectiveness of MT in detecting previously unknown bugs in real-world critical applications such as compilers and code obfuscators, we conclude that software testing of security-related features should be conducted from diverse perspectives in order to achieve greater cybersecurity.

    Allison, C.M.; Croucher, D.W.; Ploger, S.A.; Mehner, A.S.

    1977-08-01

    The report describes the results of a test using four 0.97-m long PWR-type fuel rods with differences in diametral gap and cladding irradiation. The objective of this test was to provide information about the effects of these differences on fuel rod behavior during quasi-equilibrium and film boiling operation. The fuel rods were subjected to a series of preconditioning power cycles of less than 30 kW/m. Rod powers were then increased to 68 kW/m at a coolant mass flux of 4900 kg/s-m 2 . After one hour at 68 kW/m, a power-cooling-mismatch sequence was initiated by a flow reduction at constant power. At a flow of 2550 kg/s-m 2 , the onset of film boiling occurred on one rod, Rod IE-011. An additional flow reduction to 2245 kg/s-m 2 caused the onset of film boiling on the remaining three rods. Data are presented on the behavior of fuel rods during quasiequilibrium and during film boiling operation. The effects of initial gap size, cladding irradiation, rod power cycling, a rapid power increase, and sustained film boiling are discussed. These discussions are based on measured test data, preliminary postirradiation examination results, and comparisons of results with FRAP-T3 computer model calculations

    The large-scale reflood test with a view to ensuring the safety of light water reactors was started in fiscal 1976 based on the special account act for power source development promotion measures by the entrustment from the Science and Technology Agency. Thereafter, to establish the safety of PWRs in loss-of-coolant accidents by joint international efforts, the Japan-West Germany-U.S. research cooperation program was started in April, 1980. Thereupon, the large-scale reflood test is now included in this program. It consists of two tests using a cylindrical core testing apparatus for examining the overall system effect and a plate core testing apparatus for testing individual effects. Each apparatus is composed of the mock-ups of pressure vessel, primary loop, containment vessel and ECCS. The testing method, the test results and the research cooperation program are described.

  16. Integrated Usability Testing

    Directory of Open Access Journals (Sweden)

    Andrei Ternauciuc

    2015-11-01

    Full Text Available It is essential to regularly test the usability of a learning management system, in order to ensure a fast adoption by new users and rapidly shift the focus from the platform to the content and the learning experience. Quantitative testing yields the most reliable results due to the large number of data points acquired, but lacks the in-depth analysis of the qualitative research from a controlled testing setup. We are proposing in this paper an integrated usability testing tool, which can replace a certain type of laboratory testing, where the users’ actions on the real platform are measured and analyzed. We conducted tests with the tool and compared the results with a small scale laboratory test using the same scenarios. The results seem to confirm the proposed tool as a viable alternative to the laboratory test.

    1996-01-01

    The PANDA test facility at PSI in Switzerland is used to study the long-term Simplified Boiling Water Reactor (SBWRT) Passive Containment Cooling System (PCCS) performance. The PANDA tests demonstrate performance on a larger scale than previous tests and examine the effects of any non-uniform spatial distributions of steam and noncondensables in the system. The PANDA facility is in 1:1 vertical scale, and 1:25 'system' scale (volume, power, etc.). Steady-state PCCS condenser performance tests and extensive facility characterization tests have already been conducted. A series of transient system behavior tests have been completed by end of 1995. Results from the first three transient tests (M3 series) are reviewed. The first PANDA tests exhibited reproducibility, and indicated that the SBWR containment is likely to be favorably responsive and highly robust to changes in the thermal transport patterns.

    A number of different schemes for testing superconducting coils in a simulated tokamak environment are analyzed for their merits relative to a set of test criteria. Two of the concepts are examined in more detail: the so-called cluster test scheme, which employs two large background field coils, one on either side of the test coil, and the compact torus, a low-aspect ratio toroidal array of a small number of coils in which all of the coils are essentially test coils. Simulation of the pulsed fields of the tokamak is discussed briefly

    Noninvasive prenatal testing (NIPT) refers to recently developed genetic tests of the maternal serum that allow higher detection rates of trisomy 21 and other chromosomal aneuploidies in high-risk pregnancies. Noninvasive prenatal test analyzes cell-free DNA (cfDNA) in the maternal serum. Approximately 3% to 15% of cfDNA in the maternal blood is of fetal origin. Analysis of cfDNA can help identify fetuses affected with trisomy 21 and several other fetal aneuploidies. Testing can be performed after 9 to 10 weeks' gestation and has a higher sensitivity and specificity for trisomy 21 than other aneuploidy screening test. Noninvasive prenatal test has been studied and validated in singleton pregnancies at risk for trisomy 21 secondary to advanced maternal age, an abnormal serum screen, personal or family history of aneuploidy, or abnormal ultrasound findings, if these are suggestive of trisomy 13, 18, or 21. The utilization of NIPT for genetic screening has increased rapidly since introduction of the first clinical test in October 2011. Currently, there are limitations to NIPT including the possibility of test failure (2.6%-5.4%) and the focus on only the common trisomies. Noninvasive prenatal test is a screening test, and both false-positive (0.2%-1%) and false-negative results can occur. As the technology for NIPT is further evaluated, this test is likely to be increasingly used for prenatal screening. This review provides the obstetric clinician with an update of the current issues concerning NIPT.

    INTRODUCTIONThe Regional Earthquake Likelihood Models (RELM) project aims to produce and evaluate alternate models of earthquake potential (probability per unit volume, magnitude, and time) for California. Based on differing assumptions, these models are produced to test the validity of their assumptions and to explore which models should be incorporated in seismic hazard and risk evaluation. Tests based on physical and geological criteria are useful but we focus on statistical methods using future earthquake catalog data only. We envision two evaluations: a test of consistency with observed data and a comparison of all pairs of models for relative consistency. Both tests are based on the likelihood method, and both are fully prospective (i.e., the models are not adjusted to fit the test data). To be tested, each model must assign a probability to any possible event within a specified region of space, time, and magnitude. For our tests the models must use a common format: earthquake rates in specified “bins” with location, magnitude, time, and focal mechanism limits.Seismology cannot yet deterministically predict individual earthquakes; however, it should seek the best possible models for forecasting earthquake occurrence. This paper describes the statistical rules of an experiment to examine and test earthquake forecasts. The primary purposes of the tests described below are to evaluate physical models for earthquakes, assure that source models used in seismic hazard and risk studies are consistent with earthquake data, and provide quantitative measures by which models can be assigned weights in a consensus model or be judged as suitable for particular regions.In this paper we develop a statistical method for testing earthquake likelihood models. A companion paper (Schorlemmer and Gerstenberger 2007, this issue) discusses the actual implementation of these tests in the framework of the RELM initiative.Statistical testing of hypotheses is a common task and a

    Full Text Available With absolute normal semen analysis parameters it may not be necessary to shift to specialized tests early but in cases with borderline parameters or with history of fertilization failure in past it becomes necessary to do a battery of tests to evaluate different parameters of spermatozoa. Various sperm function tests are proposed and endorsed by different researchers in addition to the routine evaluation of fertility. These tests detect function of a certain part of spermatozoon and give insight on the events in fertilization of the oocyte. The sperms need to get nutrition from the seminal plasma in the form of fructose and citrate (this can be assessed by fructose qualitative and quantitative estimation, citrate estimation. They should be protected from the bad effects of pus cells and reactive oxygen species (ROS (leukocyte detection test, ROS estimation. Their number should be in sufficient in terms of (count, structure normal to be able to fertilize eggs (semen morphology. Sperms should have intact and functioning membrane to survive harsh environment of vagina and uterine fluids (vitality and hypo-osmotic swelling test, should have good mitochondrial function to be able to provide energy (mitochondrial activity index test. They should also have satisfactory acrosome function to be able to burrow a hole in zona pellucida (acrosome intactness test, zona penetration test. Finally, they should have properly packed DNA in the nucleus to be able to transfer the male genes (nuclear chromatic decondensation test to the oocyte during fertilization.

    In this report period, efforts have concentrated on defining the requirements for shallow-flaw beam testing. Analyses have been made to envelope the significant parameters for both deep- and shallow-flaw beams for three-point loading; that is, load to initiation of a frangible flaw, load to plastic collapse, LLD, and CMOD. An assessment was made of facilities capable of performing the tests identified by the parametric analyses discussed above. Two testing machines were identified for performing the scoped test series, the first a 550-kip Instron machine assigned to the Pressure Vessel Technology Section located in Building 9204-1 at the Y-12 Plant and the second a 220-kip MTS machine assigned to a mechanical testing group located at the K-25 Site. An existing bend test fixture previously used in the HSST clad plate test series is being modified for use in testing beams under other sponsorship but will be available for shared usage with the HSST shallow-flaw beam testing activities. To prevent the shared usage from having an adverse impact on the logistics of the HSST Program, the decision was made to procure a bend test fixture tailored specifically to serve the shallow flaw beam test series. A specification was prepared and procurement initiated. A survey is in progress for determining sources and costs of displacement-measuring instrumentation from both foreign and domestic sources. It appears that existing direct current displacement transducers available to the HSST Program may be adequate for the LLD measurements. These devices will be employed in the shakedown tests that are planned. A safety and environmental survey assessment for the beam testing conforming to the revised DOE rules has been prepared and approved

    2001-02-01

    Full Text Available Given the high stakes of teacher testing, there is no doubt that every teacher test should meet the industry guidelines set forth in the Standards for Educational and Psychological Testing. Unfortunately, however, there is no public or private business or governmental agency that serves to certify or in any other formal way declare that any teacher test does, in fact, meet the psychometric recommendations stipulated in the Standards. Consequently, there are no legislated penalties for faulty products (tests nor are there opportunities for test takers simply to raise questions about a test and to have their questions taken seriously by an impartial panel. The purpose of this article is to highlight some of the psychometric results reported by National Evaluation Systems (NES in their 1999 Massachusetts Educator Certification Test (MECT Technical Report, and more specifically, to identify those technical characteristics of the MECT that are inconsistent with the Standards. A second purpose of this article is to call for the establishment of a standing test auditing organization with investigation and sanctioning power. The significance of the present analysis is twofold: a psychometric results for the MECT are similar in nature to psychometric results presented as evidence of test development flaws in an Alabama class-action lawsuit dealing with teacher certification (an NES-designed testing system; and b there was no impartial enforcement agency to whom complaints about the Alabama tests could be brought, other than the court, nor is there any such agency to whom complaints about the Massachusetts tests can be brought. I begin by reviewing NES's role in Allen v. Alabama State Board of Education, 81-697-N. Next I explain the purpose and interpretation of standard item analysis procedures and statistics. Finally, I present results taken directly from the 1999 MECT Technical Report and compare them to procedures, results, and consequences of

    2006-08-01

    The design concept of “Crashworthiness” requires the information on material behaviour under dynamic impact loading in order to describe and predict the crash behaviour of structures. Especially the transport related industries, like car, railway or aircraft industry, pursue the concept of lightweight design for a while now. The materials' maximum constraint during loading is pushed to permanently increasing figures. This means in terms of crashworthiness that the process of energy absorption in structures and the mechanical behaviour of materials must well understood and can be described appropriately by material models. In close cooperation with experts from various industries and research institutes Instron has developed throughout the past years a new family of servohydraulic testing machines specifically designed to cope with the dynamics of high rate testing. Main development steps are reflected versus their experimental necessities.

    In the evaluation of the safety of radioactive material transportation it is important to consider the response of Type B packages to environments more severe than that prescribed by the hypothetical accident sequence in Title 10 Part 71 of the Code of Federal Regulations (NRC 1995). The impact event in this sequence is a 9-meter drop onto an essentially unyielding target, resulting in an impact velocity of 13.4 m/s. The behavior of 9 packages when subjected to impacts more severe than this is not well known. It is the purpose of this program to evaluate the structural response of a test package to these environments. Several types of structural response are considered. Of primary importance is the behavior of the package containment boundary, including the bolted closure and 0-rings. Other areas of concern are loss of shielding capability due to lead slump and the deceleration loading of package contents, that may cause damage to them. This type of information is essential for conducting accurate risk assessments on the transportation of radioactive materials. Currently very conservative estimates of the loss of package protection are used in these assessments. This paper will summarize the results of a regulatory impact test and three extra-regulatory impact tests on a sample package

    Limb apraxia comprises many different and common disorders, which are largely unrecognized essentially because there is no easy-to-use screening test sensitive enough to identify all types of limb praxis deficits. We evaluated 70 right-handed patients with limb apraxia due to a single focal lesion of the left hemisphere and 40 normal controls, using a new apraxia screening test. The test covered 12 items including: intransitive gestures, transitive gestures elicited under verbal, visual, and tactile modalities, imitation of meaningful and meaningless postures and movements, and a multiple object test. Interrater reliability was maximum for a cutoff of >2 positive items identifying apraxia on the short battery (Cohen's kappa .918, p 3 items (Cohen's kappa .768, p 2 was higher, indicating greater apraxia diagnosis agreement between raters at this cutoff value. The screening test proved to have high specificity and sensitivity to diagnose every type of upper limb praxis deficit, thus showing advantages over previously published tests.

    Routine testing and prophylaxis is considered in terms of haematological disorders, biochemical testing, hormonal testing, screening for gestational diabetes and nutritional deficiencies. Within these headings the place of routine supplementation of pregnant women with iron, vitamins, trace elements and an increased protein/calorie intake is discussed. Screening for haemoglobinopathies, irregular blood group antibodies and gestational diabetes is dealt with in detail. The place for routine prophylaxis with anti-D is considered. Biochemical and hormonal testing is covered with particular reference to the use of biochemical and hormonal assays as placental function tests and their use in assessing fetal well-being. In this respect the use of biochemical and hormonal tests to screen a pregnant population for intrauterine growth retardation is also discussed.

    The pilocarpine iontophoresis test (P-test) is used as a predictor of the capacity to produce sweat. Therefore, we studied the reproducibility of this test in 12 normal subjects on 10 consecutive days. Furthermore, we determined whether the P-test reflects whole-body and regional sweat secretion...... during exercise in the heat. Finally, we determined whether the P-test stimulates the eccrine sweat glands to maximal sweat secretion. Six growth hormone-deficient (GHD) patients who are known to have decreased sweating, and 11 healthy control subjects were studied. To induce maximal sweat secretion......, the patients exercised on a bicycle ergometer at a workload corresponding to 40% of their maximal aerobic power (VO2max). The 11 healthy subjects exercised at a workload of 150 W. All subjects exercised for 60 min in ambient air at 35 degrees C, with 50% relative humidity. The P-test showed a mean day...

    Fracture mechanics and fatigue calculations for WWER reactor pressure vessels were checked by large scale model testing performed using large testing machine ZZ 8000 (with a maximum load of 80 MN) at the SKODA WORKS. The results are described from testing the material resistance to fracture (non-ductile). The testing included the base materials and welded joints. The rated specimen thickness was 150 mm with defects of a depth between 15 and 100 mm. The results are also presented of nozzles of 850 mm inner diameter in a scale of 1:3; static, cyclic, and dynamic tests were performed without and with surface defects (15, 30 and 45 mm deep). During cyclic tests the crack growth rate in the elastic-plastic region was also determined. (author). 6 figs., 2 tabs., 5 refs

    Testing plan should include Safety guide Q4 - Inspection and testing - A testing plan should be prepared including following information: General information (facility name, item or system reference, procurement document reference, document reference number and status, associated procedures and drawings); A sequential listing of all testing activities; Procedure, work instruction, specification or standard to be followed in respect of each operation and test; Acceptance criteria; Identification of who is performing tests; Identification of hold points; Type of records to be prepared for each test; Persons and organizations having authority for final acceptance. Proposed activities sequence is: visual, electrical and mechanical checks; environmental tests (thermal aging, vibrations aging, radioactive aging); performance evaluation in extreme conditions; dynamic tests with functional checks; final electrical and mechanical checks The planning of the tests should always be performed taking into account an interpretative model: a very tight cooperation is advisable between experimental people and numerical people dealing with the analysis of more or less complex models for the seismic assessment of structures and components. Preparatory phase should include the choice of the following items should be agreed upon with the final user of the tests: Excitation points, Excitation types, Excitation amplitude with respect to frequency, Measuring points. Data acquisition, recording and storage, should take into account the characteristics of the successive data processing: to much data can be cumbersome to be processed, but to few data can make unusable the experimental results. The parameters for time history acquisition should be chosen taking into account data processing: for Shock Response Spectrum calculation some special requirements should be met: frequency bounded signal, high frequency sampling, shock noise.

    1996-01-01

    Nondestructive testing (NDT) is the use of physical and chemical methods for evaluating material integrity without impairing its intended usefulness or continuing service. Nondestructive tests are used by manufaturer's for the following reasons: 1) to ensure product reliability; 2) to prevent accidents and save human lives; 3) to aid in better product design; 4) to control manufacturing processes; and 5) to maintain a uniform quality level. Nondestructive testing is used extensively on power plants, oil and chemical refineries, offshore oil rigs and pipeline (NDT can even be conducted underwater), welds on tanks, boilers, pressure vessels and heat exchengers. NDT is now being used for testing concrete and composite materials. Because of the criticality of its application, NDT should be performed and the results evaluated by qualified personnel. There are five basic nondestructive examination methods: 1) liquid penetrant testing - method used for detecting surface flaws in materials. This method can be used for metallic and nonmetallic materials, portable and relatively inexpensive. 2) magnetic particle testing - method used to detect surface and subsurface flaws in ferromagnetic materials; 3) radiographic testing - method used to detect internal flaws and significant variation in material composition and thickness; 4) ultrasonic testing - method used to detect internal and external flaws in materials. This method uses ultrasonics to measure thickness of a material or to examine the internal structure for discontinuities. 5) eddy current testing - method used to detect surface and subsurface flaws in conductive materials. Not one nondestructive examination method can find all discontinuities in all of the materials capable of being tested. The most important consideration is for the specifier of the test to be familiar with the test method and its applicability to the type and geometry of the material and the flaws to be detected

    2013-01-01

    As part of the Nuclear Systems Office Fission Surface Power Technology Demonstration Unit (TDU) project, a reactor simulator test loop (RxSim) was design & built to perform integrated testing of the TDU components. In particular, the objectives of RxSim testing was to verify the operation of the core simulator, the instrumentation and control system, and the ground support gas and vacuum test equipment. In addition, it was decided to include a thermal test of a cold trap purification design and a pump performance test at pump voltages up to 150 V since the targeted mass flow rate of 1.75 kg/s was not obtained in the RxSim at the originally constrained voltage of 120 V. This paper summarizes RxSim testing. The gas and vacuum ground support test equipment performed effectively in NaK fill, loop pressurization, and NaK drain operations. The instrumentation and control system effectively controlled loop temperature and flow rates or pump voltage to targeted settings. The cold trap design was able to obtain the targeted cold temperature of 480 K. An outlet temperature of 636 K was obtained which was lower than the predicted 750 K but 156 K higher than the cold temperature indicating the design provided some heat regeneration. The annular linear induction pump (ALIP) tested was able to produce a maximum flow rate of 1.53 kg/s at 800 K when operated at 150 V and 53 Hz.

    With over 100 models of unmanned vehicles now available for military and civilian safety, security or rescue applications, it is important to for agencies to establish acceptance testing. However, there appears to be no general guidelines for what constitutes a reasonable acceptance test. This paper describes i) a preliminary method for acceptance testing by a customer of the mechanical and electrical components of an unmanned ground vehicle system, ii) how it has been applied to a man-packable micro-robot, and iii) discusses the value of testing both to ensure that the customer has a workable system and to improve design. The test method automated the operation of the robot to repeatedly exercise all aspects and combinations of components on the robot for 6 hours. The acceptance testing process uncovered many failures consistent with those shown to occur in the field, showing that testing by the user does predict failures. The process also demonstrated that the testing by the manufacturer can provide important design data that can be used to identify, diagnose, and prevent long-term problems. Also, the structured testing environment showed that sensor systems can be used to predict errors and changes in performance, as well as uncovering unmodeled behavior in subsystems.

    This paper describes the results from aging, condition monitoring, and loss-of-coolant accident (LOCA) testing of class 1E electrical cables, per NUREG/CR-5772. This test was designed to test the performance of cables which had been aged with simultaneous radiation and thermal exposure. The tested cables included crosslinked polyolefin cables, ethylene propylene rubber cables, and miscellaneous cable types. Cables were exposed to 20, 40, and 60 years equivalent aging, and then exposed to LOCA tests at the end of their qualified life to determine the minimum insulation thickness needed for survival of the test. Failures were found in a large number of the tested cables. As a result the NRC has sent information notices to the industry regarding potential insulation problems. The results have raised the question of whether the artificial aging methods provide adequate testing methods. As a result of this testing the NRC is reviewing the artificial aging procedures, the adequacy of environmental qualification requirements for cable safety, and reexamining data from condition monitoring of installed cables

    2018-03-01

    Full Text Available Numerical simulations of rockfall trajectories are a standard procedure for evaluating rockfall hazards. For these simulations, corresponding software codes must be calibrated and evaluated based on field data. This study addresses methods of repeatable rockfall tests, and investigates whether it is possible to produce traceable and statistically analysable data. A testing series is described extensively covering how to conduct rockfall experiments and how certain elements of rockfall trajectories can be measured. The tests use acceleration and rotation sensors inside test blocks, a system to determine block positions over time, surveying measurements, and video recordings. All systems are evaluated regarding their usability in the field and for analyses. The highly detailed description of testing methods is the basis for sound understanding and reproducibility of the tests. This article serves as a reference for future publications and other rockfall field tests, both as a guide and as a basis for comparisons. First analyses deliver information on runout with a shadow angle ranging between 21 and 45 degrees for a slope consisting of homogeneous soft soil. A digital elevation model of the test site as well as point clouds of the used test blocks are part of this publication.

  20. Thermal Testing Measurements Report

    2002-09-26

    The purpose of the Thermal Testing Measurements Report (Scientific Analysis Report) is to document, in one report, the comprehensive set of measurements taken within the Yucca Mountain Project Thermal Testing Program since its inception in 1996. Currently, the testing performed and measurements collected are either scattered in many level 3 and level 4 milestone reports or, in the case of the ongoing Drift Scale Test, mostly documented in eight informal progress reports. Documentation in existing reports is uneven in level of detail and quality. Furthermore, while all the data collected within the Yucca Mountain Site Characterization Project (YMP) Thermal Testing Program have been submitted periodically to the Technical Data Management System (TDMS), the data structure--several incremental submittals, and documentation formats--are such that the data are often not user-friendly except to those who acquired and processed the data. The documentation in this report is intended to make data collected within the YMP Thermal Testing Program readily usable to end users, such as those representing the Performance Assessment Project, Repository Design Project, and Engineered Systems Sub-Project. Since either detailed level 3 and level 4 reports exist or the measurements are straightforward, only brief discussions are provided for each data set. These brief discussions for different data sets are intended to impart a clear sense of applicability of data, so that they will be used properly within the context of measurement uncertainty. This approach also keeps this report to a manageable size, an important consideration because the report encompasses nearly all measurements for three long-term thermal tests. As appropriate, thermal testing data currently residing in the TDMS have been reorganized and reformatted from cumbersome, user-unfriendly Input-Data Tracking Numbers (DTNs) into a new set of Output-DTNs. These Output-DTNs provide a readily usable data structure

  1. LHC synchronization test successful

    CERN Multimedia

    The synchronization of the LHC's clockwise beam transfer system and the rest of CERN's accelerator chain was successfully achieved last weekend. Tests began on Friday 8 August when a single bunch of a few particles was taken down the transfer line from the SPS accelerator to the LHC. After a period of optimization, one bunch was kicked up from the transfer line into the LHC beam pipe and steered about 3 kilometres around the LHC itself on the first attempt. On Saturday, the test was repeated several times to optimize the transfer before the operations group handed the machine back for hardware commissioning to resume on Sunday. The anti-clockwise synchronization systems will be tested over the weekend of 22 August.Picture:http://lhc-injection-test.web.cern.ch/lhc-injection-test/

    2010-01-01

    A test was performed to determine whether transporting and handling the undulators makes any changes to their properties. This note documents the test. No significant changes to the test undulator were observed. After the LCLS undulators are tuned and fiducialized in the Magnetic Measurement Facility (MMF), they must be transported to storage buildings and transported to the tunnel. It has been established that the undulators are sensitive to temperature. We wish to know whether the undulators are also sensitive to the vibrations and shocks of transportation. To study this issue, we performed a test in which an undulator was measured in the MMF, transported to the tunnel, brought back to the MMF, and re-measured. This note documents the test and the results.

  4. Testing for Chronic Diarrhea.

    Science.gov (United States)

    Raman, M

    Chronic diarrhea is a frequently encountered symptom in clinical practice. The etiologies for chronic diarrhea are diverse and broad with varying clinical implications. A useful method of categorizing chronic diarrhea to guide a diagnostic work-up is a pathophysiology-based framework. Chronic diarrhea may be categorized as malabsorptive, secretory, osmotic, and inflammatory or motility related. Frequently, overlap between categories may exist for any given diarrhea etiology and diagnostic testing must occur with an understanding of the differential diagnosis. Investigations to achieve a diagnosis for chronic diarrhea range from screening blood and stool tests to more directed testing such as diagnostic imaging, and endoscopic and histological evaluation. The pathophysiology-based framework proposed in this chapter will allow the clinician to select screening tests followed by targeted tests to minimize cost and complications to the patient, while providing a highly effective method to achieve an accurate diagnosis. © 2017 Elsevier Inc.

  5. Mechanical Testing of MLCCs

    Science.gov (United States)

    Teverovsky, Alexander A.

    2016-01-01

    Cracking of multilayer ceramic capacitors, MLCCs, remains a serious problem for space systems. This problem increases substantially for large size capacitors and in cases when manual soldering is involved or the system experiences mechanical shock or vibration. In any case, a fracture occurs when the sum of external and internal mechanical stresses exceeds the strength of the part. To reduce the probability of cracking, the level of stress should be reduced, e.g. by optimizing the assembly workmanship and rules for board design, and the strength of the parts increased by selecting the most mechanically robust capacitors. The latter might possibly be achieved by selecting MLCCs based on the in-situ measurements of mechanical characteristics using four types of tests: flexural strength, hardness, fracture toughness, and flex bend testing. Note that military specifications MIL-PRF-123 and MIL-PRF-55681 do not have requirements for mechanical testing of the parts. However, specifications for automotive industry components employ two types of mechanical tests: beam load (break strength) test per AEC-Q200-003 and board flex test per AEC-Q200-005. A recent military specification for thin dielectric capacitors, MIL-PRF-32535, has one mechanical test, board flex testing, that is similar to AEC-Q200-005. The purpose of this report was assessment of the efficiency of different mechanical tests for selection robust capacitors and comparison of mechanical characteristics of Base Metal Electrode (BME) and Precious Metal Electrode (PME) capacitors. The report has three parts related to the first three mechanical tests mentioned above.

    2013-09-01

    With the replacement of the current upper-stage ESC-A of the Ariane 5 launcher by an enhanced cryogenic upper-stage, ESA's Ariane 5 Midterm Evolution (A5-ME) program aims to raise the launcher's payload capacity in geostationary transfer orbit from 10 to 12 tons, an increase of 20 %. Increasing the in-orbit delivery capability of the A5-ME launcher requires a versatile, high-performance, evolved cryogenic upper-stage engine suitable for delivering multiple payloads to all kinds of orbits, ranging from low earth orbit to geostationary transfer orbit with increased perigee. In order to meet these requirements the re-ignitable liquid oxygen/liquid hydrogen expander cycle engine VINCI® currently under development is designated to power the future upper stage, featuring a design performance of 180 kN of thrust and 464 s of specific impulse. Since 2010 development tests for the VINCI® engine have been conducted at the test benches P3.2 and P4.1 at DLR test site in Lampoldshausen under the ESA A5-ME program. For the VINCI® combustion chamber development the P3.2 test facility is used, which is the only European thrust chamber test facility. Originally erected for the development of the thrust chamber of the Vulcain engine, in 2003 the test facility was modified that today it is able to simulate vacuum conditions for the ignition and startup of the VINCI® combustion chamber. To maintain the test operations under vacuum conditions over an entire mission life of the VINCI® engine, including re-ignition following long and short coasting phases, between 2000 and 2005 the test facility P4.1 was completely rebuilt into a new high-altitude simulation facility. During the past two P4.1 test campaigns in 2010 and 2011 a series of important milestones were reached in the development of the VINCI® engine. In preparation for future activities within the frame of ESA's A5-ME program DLR has already started the engineering of a stage test facility for the prospective upper stage

    1992-11-01

    A series of tests were conducted to evaluate data transfer rates using the MXIbus architecture. The tests were conducted by the DAQ group in the Physics Research Division. The MXIbus from National Instruments provides a multisystem extension interface bus. It allows multiple VME chassis to be networked. Other bus architectures that can participate in the network include VXIbus, IBM PC-AT bus, Sun Sbus, Mac NuBus and stand-alone instruments with the appropriate MXIbus adapter cards. From a functional standpoint the MXIbus provides the capability to enlarge the address space in a fashion that is transparent to the software application. The tests were designed to measure data throughput when using the MSIbus with other industry off-the-shelf hardware. This report contains discussions on: MXIbus architecture and general guidelines; the commercial hardware and software used in each set of tests; and a brief description of each set of tests, observations and guidelines; the commercial hardware and software used in each set of tests; and a brief description of each set of tests, observations and conclusions

  9. Nondestructive testing of weldings

    International Nuclear Information System (INIS)

    Ruth, U.

    1984-02-01

    Today the nondestructive testing of materials with transverse weldings would be often neglect. Because the production of this parts will get more expensive it is interesting to test the parts eg. cans with ultrasound. Within this research program we developed a testing device for automatically testing of materials with transverse weldings, e.g. tubes. Functional characteristics: after putting in the test tube in the testing device the transducer is adjusted automatically to the best adjustment. This takes place with three step motors. The mechanic of adjustments gets its information from an optimal computer. The optimal computer processes the signals, which it gets from the automatic evaluator during the adjustment and stores the optimal adjustment parameters. With an additional equipment on can identify the exact source of error, if the testing device turns out and the repairing of the part can take place very fast. With an appropiate mechanical science the devide is useable in a production line with high flow rate. (orig.) [de

    Wilhelmus, K R

    2001-01-01

    Hundreds of substances are used daily that can damage eyesight. People's eyes are open to accidental or intentional exposure during the production, transportation, use, and disposal of chemical preparations. Ensuring the safety of consumer products was born during the mid twentieth century in the aftermath of chemical warfare research, and was motivated by the hazards of unsafe cosmetics. Justified by an exigency for public protection, the Draize eye test became a governmentally endorsed method to evaluate the safety of materials meant for use in or around the eyes. The test involves a standardized protocol for instilling agents onto the cornea and conjunctiva of laboratory animals. A sum of ordinal-scale items of the outer eye gives an index of ocular morbidity. Advances in ocular toxicology are challenging the validity, precision, relevance, and need of the Draize eye test. Preclinical product-safety tests with rabbits and other mammals also raise ethical concerns of animal wellbeing. Some use the Draize test as a rallying point for how animals are treated in science and industry. A battery of cellular systems and computer models aim to reduce and ultimately to replace whole-animal testing. Molecular measures of ocular toxicity may eventually allow comprehensive screening in humans. The Draize eye test was created and refined for humanitarian reasons and has assuredly prevented harm. Its destiny is to be progressively supplanted as in vitro and clinical alternatives emerge for assessing irritancy of the ocular surface.

  12. Functional balance tests

    Directory of Open Access Journals (Sweden)

    Parvin Raji

    2012-12-01

    Full Text Available Background and Aim: All activities of daily living need to balance control in static and dynamic movements. In recent years, a numerous increase can be seen in the functional balance assessment tools. Functional balance tests emphasize on static and dynamic balance, balance in weight transfer, the equilibrium response to the imbalances, and functional mobility. These standardized and available tests assess performance and require minimal or no equipment and short time to run. Functional balance is prerequisite for the most static and dynamic activities in daily life and needs sufficient interaction between sensory and motor systems. According to the critical role of balance in everyday life, and wide application of functional balance tests in the diagnosis and assessment of patients, a review of the functional balance tests was performed.Methods: The Google Scholar, PubMed, Science Direct, Scopus, Magiran, Iran Medex, and IranDoc databases were reviewed and the reliable and valid tests which were mostly used by Iranian researchers were assessed.Conclusion: It seems that Berg balance scale (BBS have been studied by Iranian and foreign researches more than the other tests. This test has high reliability and validity in elderly and in the most neurological disorders.

    The skin prick test (SPT) is the most common test for the diagnosis of allergy. SPT is performed by pricking the skin, usually in the volar surface of the forearm, with a lancet through a drop of an allergen extract and is usually the first choice test in the diagnostic workup for allergic diseases because of its reliability, safety, convenience and low cost. SPT is minimally invasive and has the advantage of testing multiple allergens in 15 to 20 min. In children, SPT is far less disturbing than venipuncture and is used to obtain a sample of serum to measure specific IgE through in vitro tests. There is a good correlation (about 85-95%) between SPT and in vitro tests. Globally, SPT is an excellent diagnostic tool, with a positive predictive value ranging from 95-100%. SPTs can identify sensitivity to inhalants, foods, some drugs, occupational allergens, hymenoptera venom and latex. However, the relevance of such sensitivity to allergens should always be carefully interpreted in the light of the clinical history, because sensitization and clinical allergy may not coincide. In regards to safety, though the reports of systemic reactions, and particularly anaphylaxis, are very rare, in vitro IgE tests should be preferred if previous severe reactions emerge from the patient’s clinical history.

    Energy Technology Data Exchange (ETDEWEB)

    Ballou, L. B.

    1971-08-02

    For over a year we have been advocating the development of a hardened or ruggedized version of Diamond which will be suitable for sequential detonation of multiple explosives in one emplacement hole. A Plowshare-sponsored device development test, named `Yacht` is proposed for execution in Area 15 at the Nevada Test Site [NTS] in late September 1972. The test is designed to evaluate the ability of a ruggedized Diamond-type explosive assembly to withstand the effects of an adjacent nuclear detonation in the same emplacement hole and then be sequentially fired. The objectives and experimental plan for this concept is provided.

  18. Accelerated cyclic corrosion tests

    Directory of Open Access Journals (Sweden)

    Prošek T.

    2016-06-01

    Full Text Available Accelerated corrosion testing is indispensable for material selection, quality control and both initial and residual life time prediction for bare and painted metallic, polymeric, adhesive and other materials in atmospheric exposure conditions. The best known Neutral Salt Spray (NSS test provides unrealistic conditions and poor correlation to exposures in atmosphere. Modern cyclic accelerated corrosion tests include intermittent salt spray, wet and dry phases and eventually other technical phases. They are able to predict the material performance in service more correctly as documented on several examples. The use of NSS should thus be restricted for quality control.

  1. Progress test utopia.

    Science.gov (United States)

    van der Vleuten, Cees; Freeman, Adrian; Collares, Carlos Fernando

    2018-04-01

    This paper discusses the advantages of progress testing. A utopia is described where medical schools would work together to develop and administer progress testing. This would lead to a significant reduction of cost, an increase in the quality of measurement and phenomenal feedback to learner and school. Progress testing would also provide more freedom and resources for more creative in-school assessment. It would be an educationally attractive alternative for the creation of cognitive licensing exams. A utopia is always far away in the future, but by formulating a vision for that future we may engage in discussions on how to get there.

    Full Text Available The most widespread opinion among people who have some connection with software testing is that this activity is an art. In fact, books have been published widely whose titles refer to it as art, role or process. But because software complexity is increasing every year, this paper proposes a new approach, conceiving the test as a science. This is because the processes by which they are applied are the steps of the scientific method: inputs, processes, outputs. The contents of this paper examines the similarities and test characteristics as science.

    2017-01-01

    The GTK is in operation at NA62 since 2014 and is among the few silicon pixel detectors performing 4D tracking. This summer, a beam test was conducted to study the phenomena determining the detector time resolution. The project described here contributed to the beam test preparation, data taking and data analyses. One of the main goals of the test was to understand the weight field contribution to the detector time resolution. This field is distorting the signal pulse shape at the edge of the pixel. Hence, to study this effect, the position of the hits inside the pixel has to be determined. An external telescope was therefore used for this purpose.

    2013-12-01

    In this paper, are presented some possibilities concerning the implementation of a test-driven development as a programming method. Here is offered a different point of view for creation of advanced programming techniques (build tests before programming source with all necessary software tools and modules respectively). Therefore, this nontraditional approach for easier programmer's work through building tests at first is preferable way of software development. This approach allows comparatively simple programming (applied with different object-oriented programming languages as for example JAVA, XML, PYTHON etc.). It is predictable way to develop software tools and to provide help about creating better software that is also easier to maintain. Test-driven programming is able to replace more complicated casual paradigms, used by many programmers.

    2010-01-01

    Abstract—Combinatorial testing in VDM involves the automatic generation and execution of a large collection of test cases derived from templates provided in the form of trace definitions added to a VDM specification. The main value of this is the rapid detection of run-time errors caused...... by forgotten preconditions as well as broken invariants and post-conditions. Trace definitions are defined as regular expressions describing possible sequences of operation calls, and are conceptually similar to UML sequence diagrams. In this paper we present a tool enabling test automation based on VDM traces......, and explain how it is possible to reduce large collections of test cases in different ways. Its use is illustrated with a small case study....
