Components And Systems

Construction systems reduced to the smallest possible number of identical elements have long been used by architects to build structures as well as dismantle and change them as quickly, efficiently, and economically as possible. Think of the architecture of the nomads, the Crystal Palace designed by the architect John Paxton for the London World’s Fair of 1851, or the modern construction systems of the nineteenth and twentieth centuries in steel, concrete, and wood. Coupled with modern digital planning and production methods, modular precast construction systems that are adaptable for many combinations and capable of being combined with one other will play an increasingly important role in architecture in the future. The volume Components and Systems offers an in-depth and clearly organized presentation of the various types of precast building components – from semifinished products to building with components, open and closed systems, and skeleton and panel construction all the way to spatial cell constructions. The systems are accompanied by detailed drawings and color photographs. Discussions of transporting and assembling the various systems round off the topic and make this book an indispensable practical companion. Seit jeher werden in der Architektur auf möglichst wenige, gleiche Elemente reduzierte Bausysteme verwendet, um möglichst schnell, effizient und ökonomisch ein Bauwerk errichten oder auch abbauen und verändern zu können. Man denke an die Architektur der Nomaden, den Kristallpalast, der 1851 anlässlich der in London stattfindenden Weltausstellung von dem Architekten John Paxton entworfen wurde, oder die modernen Bausysteme des 19. und 20. Jahrhunderts in Stahl, Beton oder Holz. Elementierte, vorgefertigte, für viele Kombinationen anpassungsfähige und untereinander kombinierbare Systeme werden zukünftig, gekoppelt mit modernen digitalen Planungs- und Produktionsmethoden, einen immer wichtigeren Aspekt in der Architektur darstellen. Der neue Band Elemente und Systeme zeigt fundiert und übersichtlich die verschiedenen Arten vorgefertigter Bauteile auf – von Halbfabrikaten über das Bauen mit Komponenten, offenen und geschlossenen Systemen, Skelett- und Paneelbauweisen bis zu Raumzellenkonstruktionen. Ergänzt werden die Systeme durch detaillierte Zeichnungen und Farbfotos. Transport und Montage der verschiedenen Systeme runden das Thema ab und machen dieses Buch in der Praxis unverzichtbar.

Up-to-date coverage of the analysis and applications of coplanar waveguides to microwave circuits and antennas The unique feature of coplanar waveguides, as opposed to more conventional waveguides, is their uniplanar construction, in which all of the conductors are aligned on the same side of the substrate. This feature simplifies manufacturing and allows faster and less expensive characterization using on-wafer techniques. Coplanar Waveguide Circuits, Components, and Systems is an engineer's complete resource, collecting all of the available data on the subject. Rainee Simons thoroughly discusses propagation parameters for conventional coplanar waveguides and includes valuable details such as the derivation of the fundamental equations, physical explanations, and numerical examples. Coverage also includes: Discontinuities and circuit elements Transitions to other transmission media Directional couplers, hybrids, and magic T Microelectromechanical systems based switches and phase shifters Tunable devices using ferroelectric materials Photonic bandgap structures Printed circuit antennas

Industrial development of software systems needs to be guided by recognized engineering principles. Commercial-off-the-shelf (COTS) components enable the systematic and cost-effective reuse of prefabricated tested parts, a characteristic approach of mature engineering disciplines. This reuse necessitates a thorough test of these components to make sure that each works as specified in a real context. Beydeda and Gruhn invited leading researchers in the area of component testing to contribute to this monograph, which covers all related aspects from testing components in a context-independent manner through testing components in the context of a specific system to testing complete systems built from different components. The authors take the viewpoints of both component developers and component users, and their contributions encompass functional requirements such as correctness and functionality compliance as well as non-functional requirements like performance and robustness. Overall this monograph offers researchers, graduate students and advanced professionals a unique and comprehensive overview of the state of the art in testing COTS components and COTS-based systems.

It is often difficult and time consuming, if not computationally impossible, to locate a failed component in a large complex system. Recently, the U.S. Army Research and Technology Laboratories at Moffett Field, California, have established a theory stating that the minimum number of test points required for conclusive detection of system failure is equal to the total number of terminal test points; this set of points constitutes the optimal choice. In this report the authors have developed an optimal diagnostic strategy for finding a failed component in a malfunctioning system.

This book constitutes the refereed proceedings of the 41st IFIP WG 6.1 International Conference on Formal Techniques for Distributed Objects, Components, and Systems, FORTE 2021, held in Valletta, Malta, in June 2021, as part of the 16th International Federated Conference on Distributed Computing Techniques, DisCoTec 2021. The 9 regular papers and 4 short papers presented were carefully reviewed and selected from 26 submissions. They cover topics such as: software quality, reliability, availability, and safety; security, privacy, and trust in distributed and/or communicating systems; service-oriented, ubiquitous, and cloud computing systems; component-and model-based design; object technology, modularity, and software adaptation; self-stabilisation and self-healing/organising; and verification, validation, formal analysis, and testing of the above. Due to the Corona pandemic this event was held virtually.

There are good reasons why the subject of electric power engineering, after many years of neglect, is making a comeback in the undergraduate curriculum of many electrical engineering departments. The most obvious is the current public awareness of the "energy crisis. " More fundamental is the concern with social responsibility among college students in general and engineering students in particular. After all, electric power remains one of the cornerstones of our civilization, and the well-publicized problems of ecology, economy, safety, dependability and natural resources management pose ever-growing challenges to the best minds in the engineering community. Before an engineer can successfully involve himself in such problems, he must first be familiar with the main components of electric power systems. This text book will assist him in acquiring the necessary familiarity. The course for which this book is mainly intended can be taken by any student who has had some cir cuit analysis (using discrete elements, and including sinusoidal steady state) and elementary electromagnetic field theory. Most students taking the course will be in their junior or senior years. Once the course is completed, students may decide to go more deeply into the design and operation of these components and study them on a more advanced level, or they may direct their attention to the problems of the system itself, problems which are only hinted at briefly at various points herein.
