This book is designed to aid students in their preparation for JEE (Main). It is a well-planned study guide which shows through examples and challenging questions how to think analytically, and find a way to the “mysteries” of problem solving. The book leads students through a broad spectrum of levels of difficulty with the intention that they will be able to crack their examinations successfully. HIGHLIGHTS The topic-wise concepts of the subject matter have been explained in each chapter for ease of recapitulation by the students. Each chapter contains nearly 180 solved problems, from the routine to the intriguing, to test, reinforce and expand the understanding of the concepts presented. Each chapter contains a large variety of questions to hone the analytical and reasoning skills of students. The book contains three sets of mock test papers and one fully solved sample paper for practice.
In Science, experiments are as important as theory and, in subjects like Physics and Chemistry, experiments form a significant part. This compact book on Practical Physics gives all the experiments required by undergraduate students of Physics. They are chosen as per the latest university syllabi. Divided into six chapters, the book contains a large number of experiments from general Physics, properties of matter, mechanics, heat, sound, optics, magnetism and electricity. The experiments are discussed in relation to the principles involved, the apparatus used, procedures required as well as observation and result. Tables and graphs are given wherever necessary. Undergraduate students of Physics should find this book extremely useful as an adjunct text for their study.
Intended as a text for undergraduate and postgraduate courses (B.Ed./M.Ed.; B.A./M.A. Education) and diploma level courses in Education as well as for courses in Special Education, this compre-hensive and accessible book provides a sound base for understanding Special Children through an insightful and incisive discussion on Special Education. The text dwells on exceptional children, or children with special needs, who either suffer from various deficits or disabilities, or are gifted. Such children include the mentally retarded, the visually and hearing impaired, the emotionally disturbed, those with autism, cerebral palsy, and the deprived, as well as the gifted and the creative. This well...
Regular famines, frequent earthquakes, repeated floods, and similar natural calamities have always threatened human lives on earth. These environmental turbulences, in the recent times, have increased manifolds and the repercussions are felt day in and out. Uttarakhand was totally washed down by the 2014 Floods, Kathmandu got devastated by the 2015 Earthquake, and the list is endless. These increasing threats posed by the recurring natural disasters have made disaster management a prerequisite! This book provides various dimensions of Disaster Management, causes of disasters—both natural and manmade, threats posed and the ways of managing the same. Divided into 28 chapters, and organized i...
Inventory control is vitally important to almost any type of industry, whether product or service-oriented. Investments in raw materials, spare parts, work-in-progress and finished products are all critical costs of operations which if not controlled can lead to high capital costs, high operating costs, and decreased production efficiency. This book focuses on the problems of materials control in small-scale manufactur-ing industries. It explains how to optimize the available resources with a view to reducing material costs and achieving improved capital turnover. It also analyzes a few selected industries and critically reviews their performance in the area of inventory control. The book is designed as a text on inventory management for postgraduate students pursuing courses in commerce, management, and business studies. It is also suitable for all those studying for professional qualifications such as CA, ICWA, and CS.
his textbook is designed to teach a first course in Information Technology (IT) to all undergraduate students. In view of the all-pervasive nature of IT in today’s world a decision has been taken by many universities to introduce IT as a compulsory core course to all Bachelor’s degree students regardless of their specialisation. This book is intended for such a course. The approach taken in this book is to emphasize the fundamental “Science” of Information Technology rather than a cook book of skills. Skills can be learnt easily by practice with a computer and by using instructions given in simple web lessons that have been cited in the References. The book defines Information Techno...
This book provides a comprehensive introduction to the fundamental principles of modern electronic devices and circuits. It is suitable for adoption as the textbook for the first course in electronics found in most curricula for undergraduate physics and electronic science students. It also covers several topics of electronics being taught at the postgraduate first-year level in physics. Besides, the students pursuing degree or diploma courses in electrical, electronics and computer engineering will find this textbook useful and self-contained. The text provides a thorough and rigorous explanation of characteristics and parameters of the most important semiconductor devices in general use to...
Intended to cater to the needs of undergraduate students in mechanical, production, and industrial engineering disciplines, this book provides a comprehensive coverage of the fundamentals of analysis and synthesis (kinematic and dynamic) of mechanisms and machines. It clearly describes the techniques needed to test the suitability of a mechanical system for a given task and to develop a mechanism or machine according to the given specifications. The text develops, in addition, a strong understanding of the kinematics of mechanisms and discusses various types of mechanisms such as cam-and-follower, gears, gear trains and gyroscope.
A harmonious blend of the theoretical and practical aspects of educational psychology, this student-friendly text provides a base for the understanding of the subject. The book discusses the various aspects of growth and development, specifically during childhood and adolescence, and accords due importance to the cognitive aspect of human behaviour with elaborate text on intelligence, creativity, thinking, reasoning and problem-solving. Besides maintaining a logical progression of topics, the author has interspersed the text with examples and illustrations to provide an in-depth analysis of the subject matter. The book is ideally suited for the B.Ed. and B.A. (Education) courses but can also be a valuable reference for teachers, teacher-trainees, and practising counsellors at various levels of school education. KEY FEATURES • Cogent and coherent style of writing • Assignment problems and sample tests at the end of various chapters • Wide range of examples and over 50 illustrations to support and explain the topics discussed
Intended as a text for the postgraduate students of statistics, this well-written book gives a complete coverage of Estimation theory and Hypothesis testing, in an easy-to-understand style. It is the outcome of the authors’ teaching experience over the years. The text discusses absolutely continuous distributions and random sample which are the basic concepts on which Statistical Inference is built up, with examples that give a clear idea as to what a random sample is and how to draw one such sample from a distribution in real-life situations. It also discusses maximum-likelihood method of estimation, Neyman’s shortest confidence interval, classical and Bayesian approach. The difference between statistical inference and statistical decision theory is explained with plenty of illustrations that help students obtain the necessary results from the theory of probability and distributions, used in inference.
