Download Sicherheitsbewertung von Composite-Druckgasbehältern: by Mair PDF

By Mair

Das Buch zeigt einen alternativen Weg der Sicherheitsbeurteilung von Druckbehältern aus Faserverbundwerkstoffen. Dies ist insbesondere für die Mobilität der Zukunft und die zugehörige Energieversorgung mit Bio-/Erdgas und Wasserstoff von Interesse. Mit statistischen Methoden gelingt es, die Sicherheit auch jenseits der Grenzen aktueller Vorschriften fundiert zu beurteilen. Es wird dargelegt wie eine probabilistische Sicherheitsbeurteilung als replacement aussehen könnte. Dieser Ansatz basiert auf neuen Verfahren der zerstörenden Prüfung und statistischer Auswertung relevanter Festigkeitseigenschaften. Hierzu zählen die langsame Berstprüfung und ein spezielles Arbeitsdiagramm zur Auswertung von Stichproben. Darüber hinaus erlaubt der Ansatz die Quantifizierung der Degradation im Betrieb und zeigt Wege zur Abschätzung der Lebensdauer. Sicherheit wird diskutiert als Kombination von Überlebenswahrscheinlichkeit und Konsequenz.

Download Bayesian Reliability (Springer Series in Statistics) by Michael S. Hamada,Alyson Wilson,C. Shane Reese,Harry Martz PDF

By Michael S. Hamada,Alyson Wilson,C. Shane Reese,Harry Martz

Bayesian Reliability offers glossy equipment and methods for reading reliability facts from a Bayesian viewpoint. The adoption and alertness of Bayesian equipment in almost all branches of technological know-how and engineering have considerably elevated during the last few a long time. This raise is basically as a result of advances in simulation-based computational instruments for enforcing Bayesian methods.

The authors generally use such instruments all through this booklet, concentrating on assessing the reliability of elements and structures with specific consciousness to hierarchical types and versions incorporating explanatory variables. Such versions comprise failure time regression versions, sped up checking out types, and degradation versions. The authors pay distinctive consciousness to Bayesian goodness-of-fit trying out, version validation, reliability attempt layout, and insurance try making plans. in the course of the e-book, the authors use Markov chain Monte Carlo (MCMC) algorithms for enforcing Bayesian analyses -- algorithms that make the Bayesian method of reliability computationally possible and conceptually straightforward.

This publication is essentially a reference selection of glossy Bayesian equipment in reliability to be used by way of reliability practitioners. There are greater than 70 illustrative examples, so much of which make the most of real-world information. This publication is usually used as a textbook for a direction in reliability and comprises greater than one hundred sixty exercises.

Noteworthy highlights of the booklet contain Bayesian ways for the following:

  • Goodness-of-fit and version choice methods

  • Hierarchical versions for reliability estimation

  • Fault tree research technique that helps info acquisition in any respect degrees within the tree

  • Bayesian networks in reliability analysis

  • Analysis of failure count number and failure time info accrued from repairable structures, and the evaluate of assorted similar functionality criteria

  • Analysis of nondestructive and harmful degradation data

  • Optimal layout of reliability experiments

  • Hierarchical reliability coverage testing

Download Human Factors - Psychologie sicheren Handelns in by Petra Badke-Schaub,Gesine Hofinger,Kristina Lauche PDF

By Petra Badke-Schaub,Gesine Hofinger,Kristina Lauche

In Luftfahrt, Kernkraft, chemischer Industrie, Medizin und Militär arbeiten Menschen mit komplexen technischen Systemen. Doch in kritischen Situationen entscheidet der Mensch, nicht die Maschine – und das häufig unter Zeitdruck und hohem Risiko. Dabei können Fehler dramatische Konsequenzen haben. „Risikobranchen" benötigen deshalb Konzepte, die Fehlerquellen minimieren, sicheres Handeln fördern und den „Faktor Mensch" effektiver einsetzen.

Im ersten Buchteil erklären Wissenschaftler Konzepte zu Sicherheit, Fehlern und menschlichem Handeln. Im zweiten Teil stellen erfahrene Praktiker aktuelle Herausforderungen einzelner Branchen vor und präsentieren Lösungsansätze: Wie werden Prozesse und Systeme sicherer und Kommunikation effektiver gestaltet? Wie kann Komplexität reduziert werden? Welche Rolle spielen Personalführung oder neue Formen der Zusammenarbeit? Wie kann Teamarbeit trainiert werden? Sicherheitsbeauftragte, supervisor und Personaler in Risikobranchen, Ingenieure, coach und Psychologen finden in diesem Buch aktuelle Konzepte der Human-Factors-Psychologie anschaulich erklärt und mit spannenden Fallbeispielen verdeutlicht.

Download A Study of the Fukushima Daiichi Nuclear Accident Process: by Michio Ishikawa PDF

By Michio Ishikawa

Written by way of knowledgeable within the box, this e-book is ideal in the event you want to be aware of what occurred on the Fukushima Daiichi Nuclear energy Plant. half 1 of the ebook stories how middle melts happened in Fukushima Daiichi devices 1, 2, and three, respectively, in response to proof from the Three-Mile Island center soften coincidence and gasoline habit experiments played within the Nineteen Seventies less than the cooperation among the U.S., Germany, and Japan. this data explains the twist of fate procedures with out contradicting information from Fukushima, which used to be released within the TEPCO record. The hydrogen explosions in devices 1, three, and four also are defined logically along with the above center soften procedure. half 2 clarifies how the history radiation point of the location doubled: the 1st upward thrust used to be only a leak from small openings in devices 1 and three linked to fire-pump connection paintings. the second one upward push ended in direct radioactive fabric unlock from unit 2. Evacuation dose adequacy and its timing are mentioned on the subject of the twist of fate procedure, and the need for embankments surrounding nuclear energy crops to extend safety opposed to normal failures is additionally mentioned. New proposals for safeguard layout and emergency preparedness are recommended in keeping with classes discovered from the coincidence in addition to from new studies. ultimately, an idea for decommissioning the Fukushima web site and a restoration plan are introduced.

By Jinkyun Park

we expect we've got medical wisdom after we recognize the reason. (Aristotle, Posterior Analytics ebook II, half eleven) approximately 12 years in the past, while i used to be a graduate scholar, many of us have been eager about my Ph. D. subject – investigating the influence of the complexity of procedu- lized projects at the functionality of human operators operating in nuclear energy vegetation. even supposing they agreed with the truth that techniques (especially emergency working systems) play an important position in securing the security of nuclear energy crops, it used to be outstanding that the majority of them mentioned a really related factor: “I can't comprehend why working body of workers see any hassle (or complexity) in condu- ing strategies, simply because all that they've to do is to persist with an easy IF-THEN- ELSE rule as written. ” truly, this factor is heavily regarding one of many major questions i used to be lately requested, corresponding to “Don’t you're thinking that your paintings is simply too acad- ic to use to real procedures?” or “I bet we don’t have to contemplate the c- plexity of tactics, simply because we will increase a superb strategy utilizing many pr- tical approach writers’ directions.
