Dear Readers, Thanks for making it #1 Best seller on Amazon!Thrilled by responses, driven by suggestions, here is second edition of the book to add: -Analysis of real life Industrial application collected from multiple MNCs-Question bank (100 fundamental based and 50 numerical based questions)-Editing based on feedback received, to bring more valuePurpose of the book: -This book is to take you through an exciting journey of learning new mechanical engineering language, namely, Geometric Dimensioning and Tolerancing (GD&T). It is a functional language to define and communicate geometric tolerances (allowable variations) applicable to geometries (also called features) of mechanical parts and assemblies. -The purpose of this book is to learn (read and write) this language.What can the reader hope to learn by reading the book?Starting the journey with the origin of GD&T, we will learn: -Fundamentals of dimensioning, tolerancing and dimensioning rules.-Fundamental concepts of hole and shaft basis systems, basic/nominal size, limit, tolerance, actual size, deviation, allowance, and related technical terms.-Understanding mechanical features, a feature of size (FOS) and feature material condition (MMC/LMC/RFS), Datum, Datum feature, Datum feature frame, the degree of freedom, datum target, and datum simulators.-Fourteen feature controls tolerances of GD&T (straightness, flatness, circularity, cylindricity, etc.), practical application of each tolerance, the impact of MMC/LMC, understanding bonus tolerance, and writing in feature control frame.-Advanced concepts of boundary and envelope, MMB, LMB, RFB, virtual condition, resultant condition, unrelated and related actual mating envelopes.-14 most frequently used modifiers, namely, translation, projected tolerance zone, free state, tangent plane, unequally disposed profile, independency, statistical tolerance, continuous feature, controlled radius, dimension origin, between, all around, all over, and individually.-Analysis of industrial application examples, to see how industry adapts and modify the standards in real life.-100 fundamental based and 50 numerical questions to test your learning..-Appendix section including the concept of ISO-286 and IT grades, industry best practices for dimensional tolerancingWhile covering more than core GD&T concepts, a couple of designing process have also been included to provide holistic knowledge for practical purposes.About the journey of writing this book: Being a mechanical engineer, it was exciting for me to find a new evolving language in the industry. To find out the ground reality of usage of GD&T, I visited industries and educational institutes, talked to professionals, teachers, and students. Almost everywhere, a sense of difficulty to understand the new concept was found. To understand the concepts of ASME Y14.5-2009, a need of a textbook was felt, which is easy to understand, which can be used for stepwise learning, having questions, exercises, etc. I started the endeavor to write this book by contacting many of my friends, friend's friends, to collaborate and find more information, samples, industrial applications, challenges, etc. I locally printed the first sample of the book, gave it to industrial designers, Design heads, Manufacturers, Head-of-departments and Principals of colleges, established famous Authors of mechanical engineering subjects, and other colleagues. Most of them liked the book's simplified approach to describe the complex subject matter and provided their feedbacks, which are incorporated in the book. Therefore, this book is not only the output of my efforts, rather it is a combined output of many elite people working in the area of GD&T for some time now. I wish my readers to take benefit of fundamental learning and real-life examples, and to be front line runner in this evolving area of the mechanical industry!All the best! Happy learning!Ashok

"There's Plenty of Room at the Bottom" ¿ this was the title of the lecture Prof. Richard Feynman delivered at California Institute of Technology on December 29, 1959 at the American Physical Society meeting. He considered the possibility to manipulate matter on an atomic scale. Indeed, the design and controllable synthesis of nanomaterials have attracted much attention because of their distinctive geometries and novel physical and chemical properties. For the last two decades nano-scaled materials in the form of nanofibers, nanoparticles, nanotubes, nanoclays, nanorods, nanodisks, nanoribbons, nanowhiskers etc. have been investigated with increased interest due to their enormous advantages, such as large surface area and active surface sites. Among all nanostructures, nanofibers have attracted tremendous interest in nanotechnology and biomedical engineering owing to the ease of controllable production processes, low pore size and superior mechanical properties for a range of applications in diverse areas such as catalysis, sensors, medicine, pharmacy, drug delivery, tissue engineering, filtration, textile, adhesive, aerospace, capacitors, transistors, battery separators, energy storage, fuel cells, information technology, photonic structures and flat panel displays, just to mention a few. Nanofibers are continuous filaments of generally less than about 1000 nm diameters. Nanofibers of a variety of cellulose and non-cellulose based materials can be produced by a variety of techniques such as phase separation, self assembly, drawing, melt fibrillation, template synthesis, electro-spinning, and solution spinning. They reduce the handling problems mostly associated with the nanoparticles. Nanoparticles can agglomerate and form clusters, whereas nanofibers form a mesh that stays intact even after regeneration. The present book is a result of contributions of experts from international scientific community working in different areas and types of nanofibers. The book thoroughly covers latest topics on different varieties of nanofibers. It provides an up-to-date insightful coverage to the synthesis, characterization, functional properties and potential device applications of nanofibers in specialized areas. We hope that this book will prove to be timely and thought provoking and will serve as a valuable reference for researchers working in different areas of nanofibers. Special thanks goes to the authors for their valuable contributions.

'Human in Khaki' strings together real life incidents and anecdotes of an Indian Police Service officer who having been born and bred in a rural landscape emerges from IIT Delhi with an intention to serve finding his true calling as a cop. Written in a 'short stories' mode the gripping narrative brings to the fore the essence of proactive people-oriented and effective policing. With the background of real life incidents the stories bring out different facets of how outcomes could have been much worse had the police not been sensitive and perceptive to the needs of the ordinary individuals who do not have the backing of wealthy or influential people. The book addresses contemporary issues that plague modern India such as terror the widening gap between the haves and have-nots crime against women the changing value system and most significantly basic police procedure that is designed to serve the powerless and yet mostly ends up serving a powerful few. It is a very bold and honest book from a serving Police Officer which depicts stark realities of policing at district level including the tout culture in Police Stations that keeps common man away from the Police. While the book should serve as a mirror to men in uniform and the public services about their own functioning it will also allow the public at large a 'peep' into the working of the police and thus encourage and empower the man-on-the street to ensure that he is served with greater efficiency.
