Book Description
Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1 957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 29 (thesis year 1984) a total of 12,637 theses titles from 23 Canadian and 202 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 29 reports theses submitted in 1984, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

Book Description
Wireless communication is one of the most dynamic and vibrant areas of technology development in the communication field today. It has been found that severe climatic conditions disturb the propagation of electromagnetic signals at higher frequencies (greater than 30 MHz). The disturbance is mainly due to molecular absorption by oxygen for frequencies ranging between 60 and 118 GHz and due to water vapour in 22, 183 and 325 GHz bands. Rain and fog has the most significant impact, since the size of the rain drops is of the order of the wavelength of the transmitted signal. This results in energy absorption by the rain drops themselves, and as a secondary effect energy is scattered by the drops. The frequency selective absorption characteristics of the atmosphere can be approximated by a transfer function. In most of the practical channels when the signal propagates through the atmosphere the effect of many factors on the signal has to be considered along with the free space propagation channel assumption. The main objective of this study is, therefore, to find out whether, and how, the different climatic conditions are influencing radio wave propagation in GSM frequency bands in general and in Narnaul, Haryana (India) in particular. To carry out this investigation, the records of radio wave propagation along with path loss during different climatic conditions have been analyzed. On the strength of these analyses, a propagation path loss model has been developed by proposing suitable correction factors due to different climatic conditions. The validation of this developed path loss model has been verified by taking reference models and by applying practically in different urban areas. The effect of these climatic conditions on the link budget has also been analyzed.

Book Description
FULLY INTEGRATED SOLUTIONS FOR MANAGING WIRELESS NETWORK COVERAGE, CAPACITY, AND COSTS Cowritten by Dr. William C. Y. Lee, one of the original pioneers of wireless technology at Bell Labs, this in-depth guide presents accurate, effi cient propagation prediction models to meet the growing demands of next-generation wireless networks. All relevant factors, including terrain, atmospheric conditions, buildings, antenna height, indoor environments, and more, are considered. Integrated Wireless Propagation Models discusses popular prediction models and provides complete details on the Lee macrocell, microcell, and in-building models. The fi nal chapter ties the three Lee models together to produce an integrated Lee model that can be applied to all mobile environments. Throughout the book, complex mathematical models are translated into practical, easy-to-implement solutions. COVERAGE INCLUDES: Introduction to modeling mobile signals in wireless communications Macrocell prediction models--area-to-area and point-to-point models Microcell prediction models for both empirical and deterministic methods In-building (picocell) prediction models Integrating the three Lee models into the Lee comprehensive model
