Buch. Zustand: Neu. Neuware - Mechanical stress affects the magnitude of base-emitter voltages of forward biased bipolar transistors. This phenomenon is called the piezojunction effect. The piezojunction effect is the main cause of inaccuracy and drift in integrated temperature sensors and bandgap voltage references. The aim of The Piezojunction Effect in Silicon Integrated Circuits and Sensors is twofold. Firstly, to describe techniques that can reduce the mechanical-stress-induced inaccuracy and long-term instability. Secondly, to show, that the piezojunction effect can be applied for new types of mechanical-sensor structures. During IC fabrication and packaging thermo-mechanical stress is induced, when the packaged chips cool down to the temperature of application. The piezojunction effect is caused by a stress-induced change in the conductivity of the minority-charge carriers, while the piezoresistive effect is caused by a similar effect for the majority-charge carriers. To characterise the anisotropic piezojunction effect, the authors performed systematic investigations over wide ranges of mechanical stress and temperature. The experiments have been performed for various crystal and stress orientations. The experimental results have been used to extract the first- and second-order piezojunction (FOPJ and SOPJ) coefficients for bipolar transistors. It is shown how the knowledge of the piezojunction and piezoresistive coefficients can used to minimize the undesirable mechanical-stress effects on the electrical characteristics of transistors and resistors, respectively. Devices with lower mechanical-stress sensitivity can be found by comparing their piezo-coefficients. The layout of the device can also be optimized to reduce the mechanical-stress sensitivity. As a next step it is shown, how the knowledge of the piezo-effects on device level can be used to predict and to reduce their negative influence on circuit level. This is demonstrated for a number of important basic circuits, including translinear circuits, temperature transducers and bandgap references. Finally, it is shown how the piezojunction effect can be used to fabricate stress-sensing elements. It appears that, in comparison with resistive stress-sensing elements, the piezojunction sensors have the advantage of a smaller size and very low power dissipation.

Buch. Zustand: Neu. Neuware - This book deals with digital watermarking, which is defined by the authors of this book as the art of hiding auxiliary information in digital data in a secure, robust and imperceptible fashion. Digital watermarking as a topic has a long history, but before 1995 publications in scientific literature were almost absent. From 1995 onwards however the number of publications on watermarking has been steadily increasing. Today a number of workshops and conferences on this topic exist; also a number of scientific journals on watermarking have been published. This renewed scientific interest in digital watermarking has led very quickly to industrial interest, as well. In 1996 the Copy Protection Technical Working Group, a voluntary consortium consisting of the movie industry, the IT industry and the consumer electronics industry, issued a call for watermarking technologies for the purpose of copy protection of DVD-Video. A few years later the Secure Digital Music Initiative issued a similar call, in this case focusing on copy protection of digital music. These two efforts have been only partially successful: copy protection based on digital watermarking is not (yet) implemented on a large scale in any type of consumer device. This current 'failure' of watermarking, to live up to its expectations, finds its cause in a large number of reasons, ranging from legal considerations and system aspects to the relative immaturity of watermarking as a technology.

Buch. Zustand: Neu. Neuware - In this book we will explore in more detail some aspects of the Arab-Jewish divide, which raise fundamental questions regarding the place of the Arabs and Arab language education in the Jewish State. More specifically, the aim of this book is to describe and analyze language education in the Arab society in Israel from the establishment of the state in 1948 until today. For this purpose, internal processes, which are embedded within the Arab population itself were examined, such as the socio-economic condition of the population, the diglossic situation in the Arabic language, and the wide use of Hebrew among Arabic speakers. Furthermore, the book also deals with external processes such as the policy of control and inspection of the Ministry of Education over the Arab education system in general and on language education in particular, the dominance of Hebrew, and the definition and perception of Israel as a Jewish State. The influence of both internal and external processes on language education and learning achievements will also be extensively discussed.

Buch. Zustand: Neu. Neuware - Internet heterogeneity is driving a new challenge in application development: adaptive software. Together with the increased Internet capacity and new access technologies, network congestion and the use of older technologies, wireless access, and peer-to-peer networking are increasing the heterogeneity of the Internet. Applications should provide gracefully degraded levels of service when network conditions are poor, and enhanced services when network conditions exceed expectations. Existing adaptive technologies, which are primarily end-to-end or proxy-based and often focus on a single deficient link, can perform poorly in heterogeneous networks. Instead, heterogeneous networks frequently require multiple, coordinated, and distributed remedial actions. Conductor: Distributed Adaptation for Heterogeneous Networks describes a new approach to graceful degradation in the face of network heterogeneity - distributed adaptation - in which adaptive code is deployed at multiple points within a network. The feasibility of this approach is demonstrated by conductor, a middleware framework that enables distributed adaptation of connection-oriented, application-level protocols. By adapting protocols, conductor provides application-transparent adaptation, supporting both existing applications and applications designed with adaptation in mind. Conductor: Distributed Adaptation for Heterogeneous Networks introduces new techniques that enable distributed adaptation, making it automatic, reliable, and secure. In particular, we introduce the notion of semantic segmentation, which maintains exactly-once delivery of the semantic elements of a data stream while allowing the stream to be arbitrarily adapted in transit. We also introduce a secure architecture for automatic adaptor selection, protecting user data from unauthorized adaptation. These techniques are described both in the context of conductor and in the broader context of distributed systems. Finally, this book presents empirical evidence from several case studies indicating that distributed adaptation can allow applications to degrade gracefully in heterogeneous networks, providing a higher quality of service to users than other adaptive techniques. Further, experimental results indicate that the proposed techniques can be employed without excessive cost. Thus, distributed adaptation is both practical and beneficial. Conductor: Distributed Adaptation for Heterogeneous Networks is designed to meet the needs of a professional audience composed of researchers and practitioners in industry and graduate-level students in computer science.

Buch. Zustand: Neu. Neuware - Design of Multi-Bit Delta-Sigma A/D Converters discusses both architecture and circuit design aspects of Delta-Sigma A/D converters, with a special focus on multi-bit implementations. The emphasis is on high-speed high-resolution converters in CMOS for ADSL applications, although the material can also be applied for other specification goals and technologies. Design of Multi-Bit Delta-Sigma A/D Converters starts with a general introduction of the concepts of Delta-Sigma converters. A wide variety of architectures are discussed, ranging from single-loop to cascaded and various multi-bit topologies. These topologies are optimized to obtain stable converters with a high accuracy. A clear overview is provided of the maximum achievable performance of each topology, which allows a designer to select the optimal architecture for a certain specification. Special attention is paid to multi-bit architectures and possible solutions for the linearity problem of the DA converter in the feedback loop of converters. Several circuit design aspects of multi-bit Delta-Sigma converters are discussed. Various models are provided for a wide range of linear and non-linear circuit imperfections, which can degrade the performance of the converter. These models allow the designer to determine the required specifications for the different building blocks and form the basis of a systematic design procedure. The presented material is combined in a concluding chapter, which illustrates the systematic design procedure for two high-performance converters. Design of Multi-Bit Delta-Sigma A/D Converters provides a clear comparison of architectures and yields insight into the influence of the most important circuit non-idealities. It will allow you to design robust and high-performance Delta-Sigma AD converters in a shorter time. It is essential reading for analog design engineers and researchers in the field of AD convertersand it is also suitable as a text for an advanced course on the subject.

Buch. Zustand: Neu. Neuware - Medieval pilgrimage was, above all, an expression of religious faith, but this was not its only aspect. Men and women of all classes went on pilgrimage for a variety of reasons, sometimes by choice, sometimes involuntarily. They made both long and short journeys: to Rome, Jerusalem and Santiago on the one hand; to innumerable local shrines on the other. The routes that they followed by land and water made up a complex web which covered the face of Europe, and their travels required a range of support services, including the protection of rulers (who were themselves often pilgrims). Pilgrimage left its mark not only on the landscape but also on the art and literature of Europe.Diana Webb's engaging book offers the reader a fresh introduction to the history of European Christian pilgrimage in the twelve hundred years between the conversion of Emperor Constantine and the beginnings of the Protestant Reformation. As well as exploring this multi-faceted activity, it considers both the geography of pilgrimage and its significant cultural legacy.

Buch. Zustand: Neu. Neuware - Physics of Semiconductor Devices covers both basic classic topics such as energy band theory and the gradual-channel model of the MOSFET as well as advanced concepts and devices such as MOSFET short-channel effects, low-dimensional devices and single-electron transistors. Concepts are introduced to the reader in a simple way, often using comparisons to everyday-life experiences such as simple fluid mechanics. They are then explained in depth and mathematical developments are fully described. Physics of Semiconductor Devices contains a list of problems that can be used as homework assignments or can be solved in class to exemplify the theory. Many of these problems make use of Matlab and are aimed at illustrating theoretical concepts in a graphical manner.
