Molecular and Nano Electronics: Analysis, Design and Simulation,17
The most eye-catching features of these Structures are their electronic, mechanical, optical and chemical characteristics, which open a way to future applications. These properties can even be measured on single Nanotubes. For commercial application, large quantities of purified Nanotubes are needed. CNTs have also proven to be good field emitters and single molecule transistors. The small dimensions, strength and the remarkable physical properties of these structures make them a very unique material with a whole range of promising applications.

This book is focused on the thermophysical properties of complex liquids (dusty plasmas) using novel molecular dynamics simulation (MDS) methods, and will disclose the exact nature and origin of the deep understanding exist in different modes of complex liquids. New MDS methods for investigating transport properties in microelectronic (thermoelectronic and photoelectronic) devices are required for improving device design and for understanding device physics. Such methods are also required for studying new transport phenomena in nanoscale devices made of novel nanostructures, such as carbon electronics or semiconductor nanowires, nanometer size sensors to detect proteins or single DNA and nanolevel fluidic flow, nanopodwer production, nanocrystalline solar cells and polymer coatings with embedded nano particles. Plasma thermal conductivity, heat process and their nonlinear effects (non-Newtonian behaviors) are the basic data of transport property of complex liquids, and are applied for studying their flow,and heat and mass transfer characteristics. We have discussed the thermal conductivity of complex (dusty) plasmas that is an important parameter using in the heat designing system.
The result of the analysis of morphological, isozyme, RAPD and other PCR based molecular marker have been report to survey the genetic diversity among bread wheat germplasm collected from various geographical regions. Transmission of wheat to Asia through three routes was traced out by the analysis of Asian wheat landraces with isozyme and RAPD, and it was suggested that Asian wheat could be divided into at least three lineage. Quality related genes of wheat is genetically and geographically differentiated, alleles (HMW, LMW, puroindoline and waxy ) are geographically distributed. Some unique alleles are found in this study could be utilized to improve the quality of wheat proteins.
Dimension makes the difference between Microelectronics and Electronics. Can dimension play a similar role in fluid dynamics, chemistry or biology? This is the major question arising in microfluidics. This work aims at investigating some peculiar property of fluid streams at the micro scale. The results of a new designed device, gaining experience from recent literature, are promising in terms of diffusion and reaction.

Classical electronics exploits the electron charge to designate binary information, whereas spintronics is an emerging field in which the spin of the electron is used for switching purposes and to communicate information. Spin-dependent effects may arise from interactions of the electron with an external magnetic field or with magnetic properties of the conduction material. Our work considers solid-state Quantum Dots (QD''s) in an Aharonov-Bohm (AB) ring interferometer, with externally applied magnetic fields. Computational analysis of the spin-polarized electron transport through the device illustrates the principles and promise of such devices in spintronics. Device applications of an AB-ring interferometer with externally controlled QD''s include spin-polarizers and spin-filters, used to generate and select electric currents consisting primarily of a single spin state, and for use as sensors in hard drives or spin-based circuit elements. The detailed background descriptions of the AB and Zeeman effects and their computational analysis in nano-electronic circuits will be very helpful to researchers initiating investigations into this cutting-edge field.
This book presents a synthesis of various results about heat transfer of power semiconductor devices and electrical apparatus, and includes topics on thermal analysis of toroidal transformers and fast fuses used to protect power semiconductor devices, heat transfer of high breaking capacity fuses, busbars, current paths from power circuit breakers and thermal analysis of sliding contacts. Some mathematical models to study the heat transfer of busbars during transient conditions and sliding contacts with double contact points, are proposed. Starting from the fact that at high speeds of electric traction vehicles, the pantograph-catenary’s system has separation areas and electric arc appears, the possibility of power transfer from the line contact to the main electric motor through the sliding arc column, has been investigated. The book as a whole gives a comprehensive treatment of thermal modelling and numerical simulations of power semiconductor devices and assemblies, electrical equipment, and applies alike to researchers, experts, engineers, university specialists and students which study theory, design or operate with power electronic devices and electrical apparatus.
The present research work published in this book is mainly to increase the worldwide production of wheat to meet the demand of human beings.As the world is facing many environmental effects i.e. abiotic stresses mainly drought, heat etc. which directly lead to the downfall in the production of cereal crops, pulses, vegetables, fruits etc..So the scientists need to develop new varieties which can show maximum production on yield and quality basis in abiotic stress conditions by using Biotechnological tools and techniques. In the present research work small contribution was made to overcome the problem of abiotic stresses on agriculture.
This book considers analysis and design of hard handoff and soft handoff algorithms. Handoff is one of the key mechanisms in cellular network. A good handoff algorithm takes care of perfect load distribution among different Base Stations, reduce interference, and maintain cell boundary. Different handoff algorithms depending on Distance, Signal strength, Timer have been developed for mobile cellular systems. There is no dearth in literature for handoff mechanisms and algorithms. Those mechanisms and techniques are quite complicated. Analytical and simulation methods presented in this book can be easily understood.

Simulation is the means of saving time and money, especially nowadays when the electronics have evolved in very fast steps, leading to the development of complex and rather costly devices and systems. PSPICE has been developed in 1975 to cope with complex circuit design of integrated circuits and this tool has been extensively utilized for simulation of huge electronic systems and super computing processes. The intention of this book is to provide guidelines to engineering students that are involved with digital and analog experiments and projects.
