Taschenbuch. Zustand: Neu. Neuware -Gum recession is a process in which the edge of the gum tissue that surrounds the teeth disappears and recedes, and more of the tooth or tooth root is exposed. This pit becomes a place for the accumulation of food particles and bacteria. If this condition is not treated, the soft tissues and bone supporting the tooth will be severely damaged and eventually you may lose your tooth. Gum recession is a common dental problem. Most people do not notice their receding gums because it happens gradually. The first sign of gingivitis is tooth sensitivity to cold or hot foods or drinks. The tooth may also appear longer than before. You can usually feel the gap or gap around the gum line attached to the tooth. If the gingival erosion is to the extent that a little regression has occurred, the dentist can treat it only by scaling and deep cleaning of this area. In root planning, the dentist uses a special tool to carefully clean the surfaces of the tooth that are under the gums and have accumulated plaque and smooth the surface of the root of the tooth so that less plaque sticks to it and does not become a place for bacteria.Books on Demand GmbH, Überseering 33, 22297 Hamburg 100 pp. Englisch.

Zustand: Sehr gut. Zustand: Sehr gut | Sprache: Englisch | Produktart: Bücher | This book describes a unique approach to smart receiver system design. It starts with the analysis of a very basic, single-path receiver structure, then using similar methods, extends the analysis to a more complicated multi-path receiver. Within the multi-path structure, two different types of phased ¿array architectures are discussed: Analog beam-forming, and digital beam-forming. The pros and cons are studied, and the gaps are identified. Whereas previous books in this area focus mainly on phased-array circuit implementations, this book fills a gap by providing a system-level approach and introduces new methods for developing smart systems.

Zustand: Sehr gut. Zustand: Sehr gut | Sprache: Englisch | Produktart: Bücher | This book describes innovative techniques and the theoretical background for design and analysis of high performance RF/Microwave transmitters. It introduces new, robust   linearization/efficiency enhancement techniques, applicable to all of the switched mode power amplifiers. Novel analysis methods associated with these new techniques are also introduced and supporting measurement results are documented.  Innovative graphical representation methods are used to help the reader understand the matter intuitively.  Applications for the techniques discussed are very extensive, ranging from data convertors to RF/Microwave/mm-wave wireless/wire line transmitters. The authors have avoided using lengthy formulas in the discussion and have used an intuitive and simple approach to go through the necessary details.  Readers will gain valuable understanding of the dither phenomenon, its mechanism, effect and undesired side effects. The novel architectures introduced are simple, don¿t require complicated DSP techniques and are easy to implement.

Zustand: Sehr gut. Zustand: Sehr gut | Sprache: Englisch | Produktart: Bücher | The RF front-end - antenna combination is a vital part of a mobile phone because its performance is very relevant to the link quality between hand-set and cellular network base-stations. The RF front-end performance suffers from changes in operating environment, like hand-effects, that are often unpredictable. Adaptive RF Front-Ends for Hand-Held Applications presents an analysis on the impact of fluctuating environmental parameters. In order to overcome undesired behavior two different adaptive control methods are treated that make RF frond-ends more resilient: adaptive impedance control, and adaptive power control. Several adaptive impedance control techniques are discussed, using a priori knowledge on matching network properties, in order to simplify robust 2-dimensional control.A generic protection concept is presented, based on adaptive power control, which improves the ruggedness of a power amplifier or preserves its linearity under extremes. It comprises over-voltage, over-temperature, and under-voltage protection.
