Taschenbuch. Zustand: Neu. Neuware - In the beginning there was not only life but the ability to communicate and eventually to cooperate among the most basic, primeval creatures. In The Naked Neuron Dr. Joseph - an internationally respected neuroscientist and author of the highly praised The Right Brain and the Unconscious: Discovering the Stranger Within - takes us on an intriguing journey through time as he traces the evolution of communication and language from the most primitive single-celled animals to our earliest ancestors to humans today. As he so clearly demonstrates, we are linked to all levels of animals in a common bond of sensing, feeling, and communication. Be it singing wolves, dancing bees, or writhing rock and roll dancers, all communicate a treasure chest of meaning in the absence of the spoken word. Approximately 700 million years ago, a unique type of cell came into being - the neuron. This 'naked' neuron, or nerve cell, lacked a protective fatty sheath. Still, it marked a monumental and world altering development, since it would become the building block of the brain. The naked neuron generated a revolutionary change resulting in a greater complexity and subtlety of thought. Dr. Joseph vividly depicts how neurons conferred on early humans advanced powers of mental and sensory acuity, including the gift of remembering one's past and contemplating the future. Although humans possess much of the same ancient brain tissue as our fellow primates, Dr. Joseph reveals to us the singular features of the human brain that have enabled humans uniquely to develop complex, spoken language. He holds us spellbound, revealing that although the new and old brain tissue are couched within the same brain, each often has difficulty understanding the impulses and language of the other. This ground-breaking book draws on Dr. Joseph's brilliant and original research and theories, fusing the latest discoveries made in neuroscience, sociobiology, and anthropology. He illuminates how the languages of th.…

Buch. Zustand: Neu. Neuware - Modern high-capacity communication systems require filters with simultaneous good amplitude and phase responses. Selective Linear-Phase Switched-Capacitor and Digital Filters is the first coherent treatment of selective linear-phase switched-capacitor filters written by a leading international authority on the subject. Digital realizations of the same characteristics are also treated. In both cases, emphasis is laid on optimal low-sensitivity structures, a highly desirable attribute from the practical view-point. With the increasing interest in high-frequency switched-capacitor filters, the range of operation reaches a point where the phase response becomes a major design consideration, thus heightening the importance of this book. Selective Linear-Phase Switched-Capacitor and Digital Filters is an invaluable reference for electronic circuit design engineers and researchers as well as graduate students, and may be used as a text for an advanced course on the subject.…

Buch. Zustand: Neu. Neuware - As MOS devices are scaled to meet increasingly demanding circuit specifications, process variations have a greater effect on the reliability of circuit performance. For this reason, statistical techniques are required to design integrated circuits with maximum yield. Statistical Modeling for Computer-Aided Design of MOS VLSI Circuits describes a statistical circuit simulation and optimization environment for VLSI circuit designers. The first step toward accomplishing statistical circuit design and optimization is the development of an accurate CAD tool capable of performing statistical simulation. This tool must be based on a statistical model which comprehends the effect of device and circuit characteristics, such as device size, bias, and circuit layout, which are under the control of the circuit designer on the variability of circuit performance. The distinctive feature of the CAD tool described in this book is its ability to accurately model and simulate the effect in both intra- and inter-die process variability on analog/digital circuits, accounting for the effects of the aforementioned device and circuit characteristics. Statistical Modeling for Computer-Aided Design of MOS VLSI Circuits serves as an excellent reference for those working in the field, and may be used as the text for an advanced course on the subject. …

Buch. Zustand: Neu. Neuware - One of the most intriguing questions about the new computer technology that has appeared over the past few decades is whether we humans will ever be able to make computers learn. As is painfully obvious to even the most casual computer user, most current computers do not. Yet if we could devise learning techniques that enable computers to routinely improve their performance through experience, the impact would be enormous. The result would be an explosion of new computer applications that would suddenly become economically feasible (e. g. , personalized computer assistants that automatically tune themselves to the needs of individual users), and a dramatic improvement in the quality of current computer applications (e. g. , imagine an airline scheduling program that improves its scheduling method based on analyzing past delays). And while the potential economic impact of successful learning methods is sufficient reason to invest in research into machine learning, there is a second significant reason: studying machine learning helps us understand our own human learning abilities and disabilities, leading to the possibility of improved methods in education. While many open questions remain about the methods by which machines and humans might learn, significant progress has been made.…

Taschenbuch. Zustand: Neu. Neuware - The response of forests to global climate change is one of the most hotly contested issues in the greenhouse effect debate. Much effort is being devoted to the construction of models which describe the function of the forests and their rate of change. There are a wealth of techniques available to project large-scale vegetation patterns, all based on different underlying models that contain fundamental biological and ecological mechanisms. Vegetation Dynamics and Global Change will introduce both students and professionals to the sophisticated mathematical and computational tools used to predict the rate of change in the world's forests. It emphasizes the importance of scale in global studies. Leaders in the field of vegetation modeling cover physiological phenomena typically measured at small time and space scales; the stand dynamics of forests; large-scale models of forest dynamics; the reconstruction of forest vegetation of past climates as a way to understand current global changes; and the role of forests in the global carbon cycle. Several themes run through the book, including the need to understand how processes important at one time and space scale can be conceptualized at larger scales; the need to optimize the conceptual benefits of representing processes in detail and the attendant difficulties of estimating parameters and designing tests for elaborate models; and the need to identify the most appropriate system variables.…

Buch. Zustand: Neu. Neuware - As the majority of cardiovascular deaths are related to myocardial ischemia, it is necessary to understand the various aspects of ischemic heart disease. In this regard, it is noteworthy that ischemic heart disease is commonly associated with atherosclerosis, coronary spasm, as well as thrombosis leading to the development of arrhythmias, cardiovascular cell damage, myocardial infarction, cardiac hypertrophy and congestive heart failure. Furthermore, it is also important to appreciate various physiological, electrophysiological and biochemical processes in the normal heart if we are to understand their significance under pathological situations. Heart Function in Health and Disease has been organized in five sections to provide an outline of a complex problem in a convenient manner. One section of this book is devoted to shedding light on the restructuring and ontogenic changes in the developing heart whereas in the next section some hypertrophic alterations due to chronic hypoxia are described. The third and fourth sections of this book are concerned with the regulation of cardiac channels as well as signal transduction mechanisms and cardiac electric field. The fifth section contains some pathophysiological events during the development of cardiac hypertrophy and heart failure. All of these areas encompass a significant body of new information that will be invaluable to those who work in the field of cardiovascular sciences, as well as those who treat people with heart disease.…

Buch. Zustand: Neu. Neuware - Analog-to-digital (A/D) converters are key components in digital signal processing (DSP) systems and are therefore receiving much attention as DSP becomes increasingly prevalent in telephony, audio, video, consumer products, etc. The varying demands on conversion rate, resolution and other characteristics have inspired a large number of competing A/D conversion techniques. Sigma Delta Modulators: Nonlinear Decoding Algorithms and Stability Analysis is concerned with the particular class of A/D techniques called oversampled noise-shaping (ONS) that has recently come into prominence for a number of applications. The popularity of ONS converters is due to their ease of implementation and robustness to circuit imperfectors. An ONS converter consists of an encoder that generates a high-rate, low-resolution digital signal, and a decoder that produces a low-rate, high-resolution digital approximation to the analog encoder input. The conventional decoding approach is based on linear filtering. Sigma Delta Modulators presents the optimal design of an ONS decoder for a given encoder. It is shown that nonlinear decoding can achieve gains in signaling ratio and the encoder architecture. The book then addresses the instability problem that plagues higher-order ONS encoders. A new stability concept is introduced that is well-suited to ONS encoders, and it is applied to the double-loop encoder as well as to the class of interpolative encoders. It is shown that there exists a trade-off between stability and SNR performance. Based on the results, explicit design examples are presented. Sigma Delta Modulators: Nonlinear Decoding Algorithms and Stability Analysis is a valuable reference source for researchers and engineers in industry and academia working on or interested in design and analysis of A/D converters, particularly to those working in quantization theory and signal reconstruction, and can serve as a text for advanced courses on the subjects treated. …

Buch. Zustand: Neu. Neuware - Generating Abstraction Hierarchies presents a completely automated approach to generating abstractions for problem solving. The abstractions are generated using a tractable, domain-independent algorithm whose only inputs are the definition of a problem space and the problem to be solved and whose output is an abstraction hierarchy that is tailored to the particular problem. The algorithm generates abstraction hierarchies that satisfy the `ordered monotonicity' property, which guarantees that the structure of an abstract solution is not changed in the process of refining it. An abstraction hierarchy with this property allows a problem to be decomposed such that the solution in an abstract space can be held invariant while the remaining parts of a problem are solved. The algorithm for generating abstractions is implemented in a system called ALPINE, which generates abstractions for a hierarchical version of the PRODIGY problem solver. Generating Abstraction Hierarchies formally defines this hierarchical problem solving method, shows that under certain assumptions this method can reduce the size of a search space from exponential to linear in the solution size, and describes the implementation of this method in PRODIGY. The abstractions generated by ALPINE are tested in multiple domains on large problem sets and are shown to produce shorter solutions with significantly less search than problem solving without using abstraction. Generating Abstraction Hierarchies will be of interest to researchers in machine learning, planning and problem reformation.…
