Download or read book Dielectric Resonator Antennas written by Kwai Man Luk and published by Research Studies Press Limited. This book was released on 2003 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of dielectric resonator as a resonant antenna was proposed in 1983. Due to the absence of metallic loss, the dielectric resonator antenna (DRA) is highly efficient when operated at millimetre wave frequencies. With the use of high dielectric constant material, the DRA can also be used as a small and low profile antenna operated at low microwave frequencies. Low cost dielectric materials are now easily available commercially, encouraging more antenna engineers to design communication systems with DRAs.
Download or read book Metallic Materials with High Structural Efficiency written by Oleg N. Senkov and published by Springer Science & Business Media. This book was released on 2004-06-29 with total page 451 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the fall of 1998, Prof. Sergey Firstov invited me to the Frantcevych Institute for Problems of Materials Science (IPMS) in Kyiv, Ukraine to discuss possible collaborations in the area of advanced metals research. During this visit, a strong mutual interest was evident in a broad range of structural metals technologies, and a quick friendship was established. Countless subsequent emails and a reciprocal visit to the U. S Air Force Research Laboratory by Prof. Firstov and a team of scientists from IPMS ensued to discuss and detail a broad collaboration in the area of structural metals. Two years after the initial visit, a major investment by the U. S. Air Force Office of Scientific Research (AFOSR) was established to pursue the technologies defined by these interactions. The annual reviews of the AFOSR Ukrainian Metals Initiative were held in late May, a most beautiful time in Kyiv when the lilacs are in bright display and the air is scented with the smell of falling blossoms from the chestnut trees that line the major streets and many parks. The sunny days and mild evenings provide a welcome break from winter, and on weekend evenings festive crowds spill onto the Khreshchatyk, Kyiv’s downtown boulevard, to listen to street musicians, watch jugglers and comedians, or simply to celebrate with friends. The annual reviews featured long days of intensive discussion of technical progress, followed in the evenings by the warm hospitality of the Ukrainian hosts.

Book excerpt: Disturbances of various domains of cognitive function have been shown to provide a major determinant of outcome for patients with psychiatric conditions. Cognitive impairment is present in an array of diseases, including schizophrenia (with its prodromal stage), mood disorder, autism spectrum disorder, obsessive-compulsive disorder, anxiety disorder, post-traumatic disorder, and eating disorder. In an effort to develop effective therapeutics for cognitive impairment, bridging of preclinical and clinical evidence has been attempted. This edited Book will provide a forum for researchers and clinicians interested in the phenomenology, underlying mechanisms, and treatment of cognitive impairment associated with psychiatric illnesses. Twenty-eight contributions from 8 countries in Europe, Middle East, Asia, North America, and South America represent studies dealing with genetic, molecular, imaging, physiological, psychological, and behavioral issues. Information in this Book will facilitate the development of therapeutics of greater clinical value.
Download or read book A Practical Guide to Sentiment Analysis written by Erik Cambria and published by Springer. This book was released on 2017-04-07 with total page 199 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sentiment analysis research has been started long back and recently it is one of the demanding research topics. Research activities on Sentiment Analysis in natural language texts and other media are gaining ground with full swing. But, till date, no concise set of factors has been yet defined that really affects how writers’ sentiment i.e., broadly human sentiment is expressed, perceived, recognized, processed, and interpreted in natural languages. The existing reported solutions or the available systems are still far from perfect or fail to meet the satisfaction level of the end users. The reasons may be that there are dozens of conceptual rules that govern sentiment and even there are possibly unlimited clues that can convey these concepts from realization to practical implementation. Therefore, the main aim of this book is to provide a feasible research platform to our ambitious researchers towards developing the practical solutions that will be indeed beneficial for our society, business and future researches as well.
