Safety-Critical Automotive Systems - PDF
نویسندگان: خلاصه: Preface The subject of safety-critical automotive systems is growing in importance, as one can see by perusing the latest publications of SAE International. Safety has become an integral and essential part behind the engineering process for the modern vehicle. Vehicle safety is a wide-ranging discipline covering many engineering activities spanning materials, ergonomics, environmental, functional, and so forth. This book covers functional safety, also referred to as system safety. Functional (or system) safety refers to aspects of the overall safety of a vehicle that rely on the vehicle sub-systems producing correct outputs or operating correctly in response to stimuli. The most important vehicle sub-systems are the following: 1. Sensors 2. Actuators 3. Electronic control units (ECUs) 4. Communication systems 5. Software (e.g., application, middleware, drivers) Thus, it is timely that a book covering the most important aspects of functional (i.e., system) safety-critical automotive systems is published. The goals of this book are threefold: 1. To provide a quick introduction to and summary of the subject 2. To provide a classification and analysis of the recent literature on the subject 3. To reproduce the most representative of SAE publications on the subject The task of assembling a book on safety-critical automotive systems is challenging because the subject is complex, involving several technical areas that have contributed to the existing body of knowledge. In addition, the subject is by no means mature. There will be many excellent contributions and publications in the years to come. There are also many good publications in a number of worldwide conferences and/or journals. However, the intent of this book was to consider only SAE publications. Nevertheless, many of the SAE papers in this book include references to other publications. After selecting a number of papers, the question arose as to what criteria should be used to classify these papers. One possible criterion was to organize the papers around the constituent elements of a system (e.g., sensors, actuators, ECUs, communication system, software). Another criterion was to organize the papers along the steps to be followed while building a complete final system. We have decided to use the second criterion. Accordingly, the papers are organized in the following sections: 1. Introduction to safety-critical automotive systems 2. Safety processes to be followed 3. Requirements to be met 4. Analysis and design methods and techniques 5. Prototyping and target implementation 6. Testing, verification, and validation meth

TALENT DEVELOPMENT IN PARALYMPIC SPORT: RESEARCHER AND PRACTITIONER PERSPECTIVES - Original PDF
نویسندگان: خلاصه: dentifying and developing talented athletes to their fullest potential is a central concern of coaches, sports scientists, and sports policymakers. However, there is currently limited practical and theoretical knowledge for those working in Paralympic sport. A systematic review by our research team (Dehghansai et al., 2017a), for example, highlighted the clear lack of literature examining athlete development. Subsequent studies (Dehghansai et al., 2017b; Dehghansai & Baker, 2020; Dehghansai et al., 2020, 2022, 2021, Houlihan & Chapman, 2017; Patatas et al., 2020, 2022) from research groups around the world have expanded our understanding, and provided the impetus for this book, which aims to synthesize the most up-to-date research with practice across international Paralympic sport systems (e.g., from those in Australia, Belgium, Brazil, Canada, Czech Republic, United Kingdom, United States, Netherlands, and New Zealand). As part of Australia’s preparation for the Tokyo 2020 Paralympic Games, two of the authors/editors have experienced first-hand the potential opportunities for supporting athlete development. We have witnessed rapid performance trajectories, the quality and passion of coaches and other practitioners working in this field, and the creativity required to solve problems. We also observed (and experienced) many of the challenges that are highlighted and discussed at length throughout this book. We worked closely with sports which, during this period (i.e., 2016–2021), resulted in athletes winning medals at the 2020 Paralympic Games who were not even participating in that sport during the time of the previous Paralympic Games (i.e., Rio 2016 Paralympic Games
Zufallsbefunde in der Skelettradiologi - Original PDF
نویسندگان: خلاصه: Vorwort Die sich in der Radiologie schon längst etablierte und ständig weiter zunehmende Bilderflut sowie die Modalitäten und Erfolge der Krebstherapien mit ausgedehnten prätherapeutischen und langfristigen Nachsorgeuntersuchungen führen zwangsläufig zur Aufdeckung von immer mehr Zufalls- und Nebenbefunden, die vor allem dem Nichtspezialisten in der Skelettradiologie erhebli- che interpretatorische Probleme bereiten können. Doch wie geht man damit um? Sicherlich nicht, indem man die Bilderflut durch mehr oder weniger ungezielte zusätzliche Unter- suchungsverfahren ausweitet und damit unter Umständen neue Zufallsbefunde kreiert. Das gilt besonders für hoch sensitive aber weniger spezifische Modalitäten. Der anspruchsvolle und präzise Radiologe wird vielmehr ein ergänzendes Verfahren einsetzen, das – an der anatomischen Struktur des Zufallsbefunds orientiert – eine höhere Spezifität besitzt und zu einer begründeten und klinisch brauchbaren Diagnose führt. Der häufig angewendete Trick, sich der Verantwortung zu entziehen und eine histologi- sche Abklärung zu empfehlen, sollte gemieden werden. Denn die histologische Interpretation des Pathologen kann in der Skelett- radiologie nur so gut sein, wie der radiologische Befund klar und richtungsweisend ist. Ich betätige mich seit vielen Jahren als Konsiliarius in der Ske- lettradiologie. Das eingesandte Krankengut besteht zu etwa 50 % aus klinisch asymptomatischen Zufallsbefunden, hinter denen benigne Knochentumoren und tumorähnliche Läsionen, Erkran- kungen im Frühstadium, Teile einer systemischen Erkrankung, ungewöhnliche Normvarianten und vieles mehr stecken können. Es wird an mehr als 160 Fällen und fast 100 differenzialdiag- nostisch passenden Kasuistiken aufgezeigt, wie man professionell an solche Befunde unter Einbeziehung der individuellen Situation des Patienten herangeht, welche Relevanz sie haben und welche sinnvollen Empfehlungen man zum weiteren Prozedere geben kann. Mein Dank für die Überlassung der besonderen Fälle gilt den Kollegen CA Dr. med. Jürgen Wiens, Wolfsburg (Fall 22), Dr. med. Thomas Grieser, Augsburg (Fall 30), Professor Dr. med. Michael Laniado, Dresden (Fälle 34, 61), Privt.-Doz. Dr. Sönke Langner, Greifswald (Fall 45) und CA Dr. med. Nils H. Goecke, Wildes- hausen (Fall 131).
Radiologische Diagnostik Abdomen und Thorax - Original PDF
نویسندگان: خلاصه: Ultraschall, CT (Computertomografie) und MRT (Magnetreso- nanztomografie) sind die wichtigsten Modalitäten zur Unter- suchung der Kopf-Hals-Region. Gemäß den Leitlinien der Deut- schen Röntgengesellschaft (AG Kopf-Hals-Diagnostik) wird die MRT bei Verdacht auf suprahyoidale Tumoren aufgrund ihres gu- ten Weichteilkontrasts eingesetzt. Die CT kommt bei infrahyoidal gelegenen Tumoren zur Anwendung, da sie aufgrund der gerin- gen Untersuchungszeit im Vergleich zur MRT deutlich weniger artefaktanfällig ist. ●HMerke Bei der CT führt ein langes Zeitintervall nach Kontrastmittelinjek- tion (60–80 s) zur besseren Darstellung von Tumoren. Für die MRT ist gemäß den Empfehlungen der AG Kopf-Hals- Diagnostik der Deutschen Röntgengesellschaft die Durchführung mindestens folgender Sequenzen erforderlich: ● koronare fettunterdrückte T2w (T2-gewichtete) Sequenz (STIR [Short-Tau Inversion-Recovery]) mit einer Schichtdicke von 3–5 mm ● axiale T2w Sequenz mit Fettunterdrückung mit einer Schicht- dicke von 3–4 mm ● axiale und koronare native T1w (T1-gewichtete) SE-Sequenz (Spin-Echo-Sequenz) ohne Fettsättigung mit einer Schichtdicke von 3–4 mm ● axiale und koronare fettunterdrückte T1w SE-Sequenz nach i. v. (intravenöser) Kontrastmittelinjektion
Innovation and Regional Technological Convergence Theory and Evidence - Original PDF
نویسندگان: خلاصه: The concept of income convergence has drawn the attention of many economists involved in the growth debate (Alataş, 2021). Recent theories of growth and empirical studies suggest that heterogeneity with respect to technological conditions in general and total factor productivity—TFP in particular are identified as the most decisive factors for the rate of income convergence of countries (Islam, 2003). Apparently, depending on whether initial TFP differences decrease or increase over time, income convergence or divergence may be a matter of fact. This has directed researchers’ attention to the concept of technological (TFP) convergence. Although many empirical studies try to find the answer to the question of technological convergence at the country level (Dowrick & Nguyen, 1989; Wolf, 1991; Dougherty & Jorgenson, 1997; Tebaldi, 2016; Rath & Akram, 2019), regional technological convergence is the research area of relatively modest exploration. However, this situation started to change, since the importance of technological convergence and its determinants have progressively gained attention in both the scientific and the policy domains at the regional level (Rodil-Marzábal & Vence- Deza, 2020). In the context of the Lisbon Agenda (European Council, 2000) and the Europe 2020 strategy (Commission of the European Communities, 2010) goals of making Europe and its regions the most competitive and dynamic knowledge-based economies in the world, it seems crucial to find whether innovation, regarded as the main driver of regional TFP growth (Dettori et al., 2012), can stimulate technolog- ical convergence and under what conditions
Transportation Systems for Tourism - Original PDF
نویسندگان: خلاصه: The term “transportation system” is usually referred to the equipment and logistics of transporting passengers and goods. It covers the trips by all means of transport, from cars and buses to boats, aircraft, and even space travel. The objective of a transportation system is to coordinate the movement of people, goods, and vehicles in order to use routes most efficiently. When implemented, transportation systems seek to reduce transport costs and improve delivery times through effective timetabling and route management. Periodic re-evaluations and the development of alternative routes allow for timely changes to the transportation system to for increasing the efficiency. A standard transportation system will usually feature multiple timetables designed to inform the user of where each vehicle in the fleet is expected to be at any given point in time. These timetables are developed alongside an array of route plans designed to coordinate vehicle movements in a way that prevents bottlenecks in any one location. The main benefit of implementing a transportation system is delivery of goods and users to their destinations in a timely manner. This, in turn, increases the effi- ciency of vehicle use, as the same vehicle can be used for “multi-drop” jobs, such as bus services or home delivery networks, far more effectively when their routes are planned in advance rather than being generated “on the fly”. Transportation systems are developed in a wide variety of sizes. Local transport networks spanning the bus network for a city and its suburbs are common, as are country-wide delivery networks for haulage firms. Airlines use international transportation systems to coordinate their flights. The larger the distance being covered, the more effective the use of vehicles when a transportation system is used.
Degrowth Decolonization and Development When Culture Meets the Environment - Original PDF
نویسندگان: خلاصه: Degrowth Decolonization and Development offers a collection of seven original case study analyses, followed by a synopsis of concepts contributing to decol- onize development by shaking the hegemony of the Western paradigm. The partici- pating researchers met when presenting their work in Decolonization and Degrowth panels within two International Degrowth Conferences held in July (organized by Manchester University together with the Ecological Economics conference) and in August 2021 in The Hague, Netherlands. Ranging from cultural studies, critical development studies, cultural policy, cultural political economy, political economy, heterodox economic approaches, eco-feminist political ecology, to anthropology and sociology, the collection of chapters provides a broad interdisciplinary oversight of the contemporary (developmental, environmental, economic, social, cultural) chal- lenges. Precisely this interdisciplinary approach facilitates the understanding of the critical contemporary context with its complex intermingling of (positionality) crises. Our multiple analyses of Western thought, capitalist and patriarchal systems rooted in case studies depict rebellions to this hegemonic system and challenge it from complementary angles, which is the reason why we found the degrowth as most suitable framework to understand the current contemporary context and seek for post-growth alternatives. The first chapter introduces the most important concepts such as: permanent crisis, modernity and colonnialism, with associated dichotomies encaptured in the Western paradigm. We embrace the position that colonialism is not derivative but constitutive of modernity as “there is no modernity without colonial- ism” (Mignolo and Walsh 2018: 4; 107) and modern capitalism, where the cultural potential for radically necessary changes is essential—as a driver of the degrowth forces that reflects the eternal relations between man and natur
Quantitative Models in Life Science Business - Original PDF
نویسندگان: خلاصه: The pharmaceutical industry is a key, yet complex sector within the global econ- omy. Organizationally, its complexity is outlined by an involved business model, an intricate organizational structure, and a challenging environment. Economically, the pharmaceutical industry has been characterized by high profit margins; this mainly as a result of substantial research and development (R&D) investment and its legal protection by patents. Over time the original situation has evolved further, gener- ating two major types of pharmaceutical firms: originators and generic producers. High R&D investment is a characteristic of the originator pharmaceutical companies which produce patent-protected drugs, as well as biotech specialists which produce biologics. The generic producers, on the other hand, do not incur the initial R&D expenses (or less so) and in general produce drugs lacking patent protection. On top of this now traditional set, new segments have arisen in the pharmaceutical indus- try, comprising services in or around the traditional drug industry, e.g. diagnostic or data-oriented endeavours.آیا کتاب مورد نظر هنوز بر روی سایت قرار نگرفته است؟ جای نگرانی نیست! کافی است بر روی گزینه سفارش کتاب کلیک کرده و درخواست خود را ثبت کنید. در کمتر از چند ساعت کتاب شما را آماده خواهیم کرد.
