| h rashid: Electric Renewable Energy Systems Muhammad Harunur Rashid, 2015 This derivative volume stemming from content included in our seminal Power Electronics Handbook takes its chapters related to renewables and establishes them at the core of a new volume dedicated to the increasingly pivotal and as yet under-published intersection of Power Electronics and Alternative Energy. While this re-versioning provides a corollary revenue stream to better leverage our core handbook asset, it does more than simply re-package existing content. Each chapter will be significantly updated and expanded by more than 50%, and all new introductory and summary chapters will be added to contextualize and tie the volume together. Therefore, unlike traditional derivative volumes, we will be able to offer new and updated material to the market and include this largely original content in our ScienceDirect Energy collection. Due to the inherently multi-disciplinary nature of renewables, many engineers come from backgrounds in Physics, Materials, or Chemical Engineering, and therefore do not have experience working in-depth with electronics. As more and more alternative and distributed energy systems require grid hook-ups and on-site storage, a working knowledge of batteries, inverters and other power electronics components becomes requisite. Further, as renewables enjoy broadening commercial implementation, power electronics professionals are interested to learn of the challenges and strategies particular to applications in alternative energy. This book will bring each group up-to-speed with the primary issues of importance at this technological node. This content clarifies the juncture of two key coverage areas for our Energy portfolio: alternative sources and power systems. It serves to bridge the information in our power engineering and renewable energy lists, supporting the growing grid cluster in the former and adding key information on practical implementation to the latter. |
| h rashid: SPICE for Power Electronics and Electric Power Muhammad H. Rashid, 2017-12-19 Power electronics can be a difficult course for students to understand and for professors to teach. Simplifying the process for both, SPICE for Power Electronics and Electric Power, Third Edition illustrates methods of integrating industry standard SPICE software for design verification and as a theoretical laboratory bench. Helpful PSpice Software and Program Files Available for Download Based on the author Muhammad H. Rashid’s considerable experience merging design content and SPICE into a power electronics course, this vastly improved and updated edition focuses on helping readers integrate the SPICE simulator with a minimum amount of time and effort. Giving users a better understanding of the operation of a power electronics circuit, the author explores the transient behavior of current and voltage waveforms for each and every circuit element at every stage. The book also includes examples of all types of power converters, as well as circuits with linear and nonlinear inductors. New in this edition: Student learning outcomes (SLOs) listed at the start of each chapter Changes to run on OrCAD version 9.2 Added VPRINT1 and IPRINT1 commands and examples Notes that identify important concepts Examples illustrating EVALUE, GVALUE, ETABLE, GTABLE, ELAPLACE, GLAPLACE, EFREQ, and GFREQ Mathematical relations for expected outcomes, where appropriate The Fourier series of the output voltages for rectifiers and inverters PSpice simulations of DC link inverters and AC voltage controllers with PWM control This book demonstrates techniques of executing power conversions and ensuring the quality of the output waveforms rather than the accurate modeling of power semiconductor devices.

| h rashid: Digital Power Electronics and Applications Fang Lin Luo, Hong Ye, Muhammad H. Rashid, 2010-07-20 The purpose of this book is to describe the theory of Digital Power Electronics and its applications. The authors apply digital control theory to power electronics in a manner thoroughly different from the traditional, analog control scheme. In order to apply digital control theory to power electronics, the authors define a number of new parameters, including the energy factor, pumping energy, stored energy, time constant, and damping time constant. These parameters differ from traditional parameters such as the power factor, power transfer efficiency, ripple factor, and total harmonic distortion. These new parameters result in the definition of new mathematical modeling: • A zero-order-hold (ZOH) is used to simulate all AC/DC rectifiers. • A first-order-hold (FOH) is used to simulate all DC/AC inverters. • A second-order-hold (SOH) is used to simulate all DC/DC converters. • A first-order-hold (FOH) is used to simulate all AC/AC (AC/DC/AC) converters. Presents most up-to-date methods of analysis and control algorithms for developing power electronic converters and power switching circuits Provides an invaluable reference for engineers designing power converters, commercial power supplies, control systems for motor drives, active filters, etc. Presents methods of analysis not available in other books |

| h rashid: Multicomponent Hydrogels Jagan Mohan Dodda, Kalim Deshmukh, Deon Bezuidenhout, 2023-05-22 Hydrogels are highly hydrated three dimensional networks with the ability to mimic the extracellular matrix of bodily tissues and have thus found application in a wide range of biomedical applications. Unique physiochemical properties such as biocompatibility, water permeability, stimuli responsiveness and self-healing characteristics make them especially useful for use as scaffolds and matrices drug delivery, tissue engineering/regeneration and sensing. Their weak and brittle nature, however, often limits their widespread application where improved mechanical strength is required. To resolve this problem, there has been a significant amount of research into the improvement of their mechanical properties. Among these efforts, versatile multicomponent hydrogels have received much attention as their physiochemical properties can be structurally engineered to provide a wide range of desired properties. These multicomponent formulations also allow for the combination of natural and synthetic polymers, which offers the scope to exploit the advantages of each component, with the synergistic effects resulting from mutual interactions. This book critically discusses the fundamental chemistry, synthesis, characterisation, physiochemical and biological properties of various types of multicomponent hydrogels. It reviews the different strategies employed in designing and synthesizing cutting-edge multicomponent hydrogels and their key applications in biomedical fields. The work is suitable for researchers working in the specific area of multicomponent hydrogels, and also more generally for those working in materials science, biomedical engineering, biomaterials science and tissue engineering. |

| h rashid: Modern Electrical Drives H. Bülent Ertan, M. Yildirim Üçtug, Ron Colyer, Alfio Consoli, 2013-06-29 Electrical drives lie at the heart of most industrial processes and make a major contribution to the comfort and high quality products we all take for granted. They provide the controller power needed at all levels, from megawatts in cement production to milliwatts in wrist watches. Other examples are legion, from the domestic kitchen to public utilities. The modern electrical drive is a complex item, comprising a controller, a static converter and an electrical motor. Some can be programmed by the user. Some can communicate with other drives. Semiconductor switches have improved, intelligent power modules have been introduced, all of which means that control techniques can be used now that were unimaginable a decade ago. Nor has the motor side stood still: high-energy permanent magnets, semiconductor switched reluctance motors, silicon micromotor technology, and soft magnetic materials produced by powder technology are all revolutionising the industry. But the electric drive is an enabling technology, so the revolution is rippling throughout the whole of industry. |

Text and image are compared to elucidate the characteristics of each medium and to arrive at a comprehensive picture of the royal rhetoric of the time. The book includes a catalogue of all artifacts, and a translation of selected text passages. |
| h rashid: The Implications of Climate and Sea-Level Change for Bangladesh R.A. Warrick, Q.K. Ahmad, 2012-12-06 Although the greenhouse effect and global climate change have been the subjects of scientific scrutiny for many decades, only recently have they received widespread public attention. Two major events helped generate this attention. First, in 1990 the Intergovernmental Panel on Climate Change (IPCC) published its findings on the science, impacts and policy implications of climate change. The findings of the IPCC, prepared and reviewed extensively by the world's leading experts in the field, confirmed that the increasing atmospheric concentrations of greenhouse gases, such as carbon dioxide, methane, nitrous oxide and the chlorofluorocarbons, could cause the world to warm and sea level to rise. Second, in 1992 the United Nations Conference on Environment and Development (UNCED) inRio de Janeiro focussed the attention of the world's national governments, as well as organisations and individuals outside the governments, on the threat of global climate change. The Framework Convention on Climate Change (FCCC), signed by nations at UNCED, reflects both the concern about the effects of climate change and the urgent need for action to prevent or reduce its potential impacts, particularly with respect to the vulnerable developing countries of the world. Bangladesh ratified the FCCC on 15 April 1994. The countries that have signed and ratified the FCCC are obligated to report to the Conference of the Parties (CoP) to the Convention on a number of inter related issues. |

| h rashid: Ethnobiology of Uzbekistan Olim K. Khojimatov, Yusufjon Gafforov, Rainer W. Bussmann, 2023-08-25 Natural resources and associated biological diversity provide the basis of livelihood for humans, particularly in rural areas and mountain regions around the world. Over centuries, indigenous peoples, traditional societies and local communities have developed their own specific knowledge regarding plant use, management, and conservation. The history of plant use by humans as food and to treat diverse ailments dates back to ancient civilizations. Even though the advent of allopathic medicine has somehow minimized the role of medicinal plants in favor of synthetic drugs, a number of modern drug discoveries have been based on medicinal plants used by indigenous peoples. Ethnobiology is the burgeoning interdisciplinary scientific field which covers all sorts of interactions between plants and people, and Central Asia is recognized as a plant diversity hot spot. The mountains and valleys of this region are rich in unique medicinal and food plant species. Local communities residing in the mountain regions of Central Asia possess unique knowledge of surrounding resources, which is the result of many years of interaction with and selection of the most desirable and pervasive plant species present. In this context, this book provides comprehensive information on cross-culture variation in the traditional uses of plants, fungi, and animal species as food, medicine, and for cultural purposes among the diverse communities of Uzbekistan. The key areas of focus include plant diversity in Uzbekistan, cross cultural variation in traditional uses of plant species, high-value medicinal and food plant species, and threats and conservation status of plant species and traditional knowledge |
| h rashid: 100 Years of Human Chorionic Gonadotropin Laurence A. Cole, Stephen A. Butler, 2020-02-17 100 years of Human Chorionic Gonadotropin: Reviews and New Perspectives is a collection of articles written by some of the world's leading experts on the pregnancy hormone and cancer marker hCG. In 2019 it is difficult to ignore the effect that our understanding of hCG has had on the lives of millions of people worldwide. The hCG immunoassay, in one form or another, is now one of the most common medical tests conducted and is often the first indication that a mother-to-be is pregnant. Not only a marker of pregnancy, hCG is utilized in the diagnosis and monitoring in oncology and presents a potential target for novel cancer therapeutics. 100 years ago, in 1919, Hirose was demonstrating gonadotropic functions which resulted from a chorionic factor. Over the last century this factor has become defined as hCG and more recently explored as not one molecule but a group of molecules with variable structure and variable functions in both pregnancy and cancer. hCG is a multi-faceted molecule that has clinical and therapeutic implications but can be a challenging topic for researchers and physicians alike. This text covers the different structures and functions of hCG exploring the genes and evolution of the molecule, the different protein and glycosylation structures which can exist and their effect on structure, detection and quantification. 100 Years of hCG is not an attempt to recount the history of every publication on hCG, but rather a collection of reviews and new perspectives by hCG-ologists, the term used by Hussa to describe biochemists working on HCG in the first book written on the topic over 30 years ago. Some of the authors have been around a while, some not so long, but others are just beginning their journey with a most beguiling molecule. Provides updated information on a complex and changing subject in five sections Reviews historical perspectives and developments over the last 100 years Includes novel insights into the structure, function and detection of hCG in pregnancy and cancer Includes chapters on the use of mass spectrometry to detect and quantify hCG as well as traditional immunoassays and over the counter pregnancy tests Describes the role of hCG in pregnancy, endometrial receptivity and embryo implantation and the use in fertility treatment Addresses the specific hyperglycosylated hCG test that can distinguish a normal term from a failing pregnancy and also screen for preeclampsia and gestational hypertension in pregnancy as well as its use as a marker and treatment target in cancer.
