Описание:A RoF system having 2-10 km radius (micro/macro cells) give excellent performance in the improvements of BER as well as Q-factor. A bidirectional SCM-ASK model for RoF communication system that incorporates optical mm-wave generation and wavelength reuse for uplink connection has been proposed in this work. For short and medium distance RoF system, various parameters such as laser source power level (in dBm), laser linewidth (in MHz), number of RF channels and their frequency spacing, EDFA gain and power and MZM bias and modulation voltages should be carefully chosen for achieving minimum bit error rate (BER) and high Q-factor. Radio over Fiber (RoF) technique combines high capacity of optical fiber and mobility of cellular radio system for next generation speedy networks due to well known advantages like ultrahigh bandwidth, elimination of frequency congestion, low transmission loss, low power consumption and mobility to serve both fixed and mobile users.

PAPM UWB Communication System. Concepts, Modeling, Capacity Analysis
Although M-ary Pulse Position Modulation (PPM) has better performance than M-ary Pulse Amplitude Modulation (PAM) for M>2 in an UWB environment, it requires more accurate timing synchronization and has a higher computational complexity, particularly for large M. This book, therefore, provides a hybrid modulation scheme, called pulse amplitude position modulation (PAPM), which combines PPM and PAM constellations to provide a compromise between system performance and complexity. It contains concepts, modeling, capacity analysis of PAPM UWB System. The analysis of PAPM UWB should help understand other modulation schemes as the basic hybrid UWB system and should be useful to anyone else who may be considering utilizing UWB system with asynchronous multiple user interference. In the future of digital home networking, Ultra-Wideband (UWB) technology will be used as a wireless communication system to connect various devices like HDTVs, PCs, and Cell phones. One of the major challenges when designing UWB systems is the selection of the appropriate modulation scheme.

Echoes of the Past. The Conflict over the Position of Women in the Early Islamic Community
Using primarily the Qur' an, sunna, hadith, and early histories of the period, Fritz attempts to use a dispassionate, historical approach in examining this issue. In so doing, he finds that the early Islamic community was heavily divided on the role of women in the public spehre, much like the modern community, rather than universally liberating or oppressive toward women. Echoes of the Past is an examination of the debate within the 7th century Islamic community over the role of women in public life.

This work includes the comparison of the micro structural simulated FE-models with existing empirical and semi analytical formulations like Mori-Tanaka and the interpolative double inclusion (Lielens' Model) that are used extensively in material modeling. Material characterization experiments are done on a particle reinforced polymer composite and its unfilled matrix to extract the material properties then compared with numerical homogenization applied on our micro material models. Different cases of numerical homogenization are examined. The isotropic case assumed for the particle filled composites (spherical incl. ) and the transverse isotropic/Orthotropic cases assumed of the fully- aligned/General-Orientation fiber reinforced composites (sphero-cylindrical and cylindrical inclusions). This work deals with the determination of macroscopic material properties of polymer composites by meso-mechanical numerical modeling. Focus is laid on the methodology how to build up appropriate representative volume elements (RVE) to describe the microstructure of spherical-particles and fibers reinforced composites and how to apply appropriate 3D boundary conditions.
