What started as a very focused and practical attempt to improve network management, touched in its lifetime upon broader issues of the use of radio spectrum, design of system architectures for the wireless medium, and image formation outside the limits of geometrical optics. Ihaveintendedthisbookmostlyfortheaudienceofengineersandsystemdesi- ers, in the growing eld of radio communication among small, portable, ubiquitous devices that have become hybrid platforms for personal communication and p- sonal computing. It is also a book addressed to network professionals, people to whom radio is largely a black box, a medium that they usually rely upon, but s- dom fully understand. In fact, in the course of my work in the eld, I have witnessed, to my dismay, a wide disconnect between the networking world and the radio technology that n- working has come to depend upon so heavily. Perhaps, because digital wireless communication is seen as digital rst and wireless second, there is often a m- placed emphasis on its information-processingside, with the methodologycentered around the discrete symbol, and with little intuition of the underlying physics. I had it once suggested to me, in apparent seriousness, to use radio cards for intra-system communication within a radiolocator! Wireless communication is radio, plain and simple. 204 pp. Englisch.

Buch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Medical Imaging Informatics provides an overview of this growing discipline, which stems from an intersection of biomedical informatics, medical imaging, computer science and medicine. Supporting two complementary views, this volume explores the fundamental technologies and algorithms that comprise this field, as well as the application of medical imaging informatics to subsequently improve healthcare research. Clearly written in a four part structure, this introduction follows natural healthcare processes, illustrating the roles of data collection and standardization, context extraction and modeling, and medical decision making tools and applications.Medical Imaging Informatics identifies core concepts within the field, explores research challenges that drive development, and includes current state-of-the-art methods and strategies. 446 pp. Englisch.

Buch. Condición: Neu. This item is printed on demand - Print on Demand Titel. Neuware -Foreword by Walter J. Freeman.The induction of unconsciousness using anesthetic agents demonstrates that the cerebral cortex can operate in two very different behavioral modes: alert and responsive vs. unaware and quiescent. But the states of wakefulness and sleep are not single-neuron properties---they emerge as bulk properties of cooperating populations of neurons, with the switchover between states being similar to the physical change of phase observed when water freezes or ice melts. Some brain-state transitions, such as sleep cycling, anesthetic induction, epileptic seizure, are obvious and detected readily with a few EEG electrodes; others, such as the emergence of gamma rhythms during cognition, or the ultra-slow BOLD rhythms of relaxed free-association, are much more subtle. The unifying theme of this book is the notion that all of these bulk changes in brain behavior can be treated as phase transitions between distinct brain states.Modeling Phase Transitions in the Brain contains chapter contributions from leading researchers who apply state-space methods, network models, and biophysically-motivated continuum approaches to investigate a range of neuroscientifically relevant problems that include analysis of nonstationary EEG time-series; network topologies that limit epileptic spreading; saddle--node bifurcations for anesthesia, sleep-cycling, and the wake--sleep switch; prediction of dynamical and noise-induced spatiotemporal instabilities underlying BOLD, alpha-, and gamma-band Hopf oscillations, gap-junction-moderated Turing structures, and Hopf-Turing interactions leading to cortical waves.Springer-Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 336 pp. Englisch.

Buch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The field of minimally invasive spine intervention continues to evolve rapidly. Numerous changes and developments have been added to our tools and capabilities over the past decade. Image-Guided Spine Interventions, Second Edition, describes the v- ied and numerous tools that are available to the physicians who are involved in providing these procedures to appropriate patients. This book embraces clinical evaluation, pharmacological requirements, p- cedural recommendations, and a spectrum of procedures that will be of interest to the minimally invasive spine interventionalist. It covers a broad range of material that is presented by experts in each field, such as discography, percutaneous discectomy, vertebroplasty and balloon kyphoplasty, epidural steroid injections, selective nerve root blocks, autonomic nerve blocks, spinal stimulator implantation, and spine v- cular intervention. This book will be useful to all physicians who deal with back pain, including pain anesthesiologists, spine neurosurgeons, orthopedists, and radiologists. Both editors have clinical practices devoted solely to spine pro- dures and pain management. This rewarding area has grown rapidly, and it provides great opportunities for clinical development as well as potential to aid a very needy patient population. We sincerely hope this work will be useful in helping our colleagues - new and old - establish, grow, and refine a minimally invasive spine interventional practice. 416 pp. Englisch.
