The switched reluctance machine (SRM) is the least expensive electrical machine to produce, yet one of the most reliable. As such, research has blossomed during the last decade, and the SRM and variable drive systems using SRMs are receiving considerable attention from industry. Because they require a power electronic converter and controller to function, however, successful realization of an SRM variable drive system demands an understanding of the converter and controller subsystems and their integration with the machine. Switched Reluctance Motor Drives provides that understanding. It presents a unified view of the machine and its drive system from all of its system and subsystem aspects. With a careful balance of theory and implementation, the author develops the analysis and design of SRMs from first principles, introduces a wide variety of power converters available for driving the SRM, and systematically presents both low- and high-performance controllers. The book includes an in-depth study of acoustic noise and its minimization along with application examples that include comparisons between ac and dc drives and SRM drive. The result is the first book that provides a state-of-the-art knowledge of SRMs, power converters, and their use with both sensor-based and sensorless controllers. Switched Reluctance Motor Drives enables both students and engineers to learn all aspects of SRM drive systems and appreciate the interdependence of the various subsystems in performance optimization.
The Mahabharata describes the Krishnavatara because Krishna plays a major role. The teaching of Bhagavad Gita to Arjuna is a precious jewel found in it. Then there is a long chapter of Bhishma's advice to Yudhishthira including the Vishnu Sahasranama, which is chanted by many. This epic is considered even as the fifth Veda. The Mahabharata - Unfolding the timeless classic of victory of time.
Ramayana and Mahabharata are called The Itihasas. Itihasa in Sanskrit literally means ‘it happened thus’. So these are to be distinguished from the Puranas. Ithihasas were composed or written by those who witnessed what was happening so these are historical accounts. Valmiki lived during Ramayana period as did Veda Vyasa during The Mahabharata. Valmiki’s Ramayana is in the form of poetry and is of great beauty. It is considered as the world’s first poetry. It is set to Anushtup meter. It is the original version and there are several other versions written much later which were inspired from that of Valmiki. I am a scientist by profession and hence the type of treasure that I searched in Valmiki’s great work and my view of things could be somewhat different and perhaps be of interest. So I decided to find out for myself such details. I was very much impressed to find so many rich details and interesting information on several aspects of Tradition, Culture, Astronomy, Geography and so on and which are not generally talked about. Valmiki’s deep knowledge of Astronomy and Astrology is amazing. I was surprised to discover that iron was already in use in Ramayana period. Let us note that the westerners attribute a much later period for the use of iron and also claim that the knowledge of planets came to India from the Greeks!
Studienarbeit aus dem Jahr 2018 im Fachbereich BWL - Sonstiges, , Sprache: Deutsch, Abstract: The study material on the “Application of Remote Sensing and GIS in Fisheries” is a humble attempt to convey the physical understanding about the techniques like GIS and Remote sensing to the students from fisheries. Realizing the need for a material describing the application especially in fisheries sector, it was my fervid aspiration to develop a text book. The Worlds highest producer of fish and fishery products from capture fisheries are identified as major fishing areas by FAO. The countries within the Southeast Asian region considered as a major producer of capture fisheries. In 2019, the world’s fisheries production was amounted to 195.7 million metric tons (MT) of which, 94.6 million MT was from capture fisheries and 101.1 came from aquaculture. Southeast Asian region accounted for about 42.2 million MT that constitute around 22% of the total landing. Among them, Indonesia, the highest producer generated about 20.6 million MT. Considering this scenario, the effective management of the region’s inland and coastal areas is very essential to reinforce the trend of fisheries and aquaculture in geographical region and thereby can ensure food security of peoples within the whole world. There are existing technologies that would be used for better planning and management of fisheries and aquaculture, e.g. GIS and Remote Sensing technologies. The usage of those technologies is therefore worth exploring, especially in obtaining the required information for formulating appropriate approaches, policies, further as management plans for medium and long-term sustainable utilization of fishery resources and environmental facilities for fisheries and aquaculture.
In "Marketing Research," the authors offer undergraduate and MBA students a compelling introduction to the field with extensive use of global, technology, service, and small business examples. Distinctive features include integrated coverage of technology tools and statistical analysis, current research, and a strong focus on strategy. To reinforce the text's emphasis on technology, each new copy of the text can be packaged with SPSS software containing data sets--created by the authors--specifically related to examples and tutorials from the chapters on data analysis."Case in Point" sections appear after the introduction of each major topic to reinforce key information with detailed examples."Research in Use" boxes provide a variety of interesting real-world examples--often featuring offbeat or unique scenarios--that in some instances have been researched firsthand by the authors.Chapter 5, "Using Geographic Information Systems for Marketing Research," devotes special attention to an important tool used in contemporary marketing research.
