Heat & Mass Transfer Author(s) Dr. D.S. Kumar
The book is written for an undergraduate course on the Feedback Control Systems. It provides comprehensive explanation of theory and practice of control system engineering. It elaborates various aspects of time domain and frequency domain analysis and design of control systems. Each chapter starts with the background of the topic. Then it gives the conceptual knowledge about the topic dividing it in various sections and subsections. Each chapter provides the detailed explanation of the topic, practical examples and variety of solved problems. The explanations are given using very simple and lucid language. All the chapters are arranged in a specific sequence which helps to build the understanding of the subject in a logical fashion. The book starts with explaining the various types of control systems. Then it explains how to obtain the mathematical models of various types of systems such as electrical, mechanical, thermal and liquid level systems. Then the book includes good coverage of the block diagram and signal flow graph methods of representing the various systems and the reduction methods to obtain simple system from the analysis point of view. The book further illustrates the steady state and transient analysis of control systems. The book covers the fundamental knowledge of controllers used in practice to optimize the performance of the systems. The book emphasizes the detailed analysis of second order systems as these systems are common in practice and higher order systems can be approximated as second order systems. The book teaches the concept of stability and time domain stability analysis using Routh-Hurwitz method and root locus method. It further explains the fundamentals of frequency domain analysis of the systems including co-relation between time domain and frequency domain. The book gives very simple techniques for stability analysis of the systems in the frequency domain, using Bode plot, Polar plot and Nyquist plot methods. It also explores the concepts of compensation and design of the contr

In such high level exams like NEET there are lakhs of aspirants who are enrolling every year to just limited number of seats, so having conceptual knowledge with thorough practice is the only key to success in such examinations. There is a neck to neck competition in every entrance examinations so, the main concern for the students who are preparing is to know the types of questions, important questions, Question paper pattern and styling of the answers that are expected to come in the examination. Keeping this in mind, the current edition of “32 years’ chapter wise solution (1988-2019) NEET & AIPMT Physics (one of the major subjects) has been provided with correct solutions, detailed explanatory discussions of the answers and each and every concept accompanied by the important formulae for 23 main chapters. This chapter wise guide of physics give the complete idea of exactly what kind of questions are being asked in the papers of NEET SOLVED PAPER 2018, NEET (NATIONAL) PAPER – 2019, NEET (ODISHA) PAPER – 2019. Thorough practice done from this will guarantee students in getting success in this examination.

New simplified physics class 12 SL ARORA
New Simplified Physics: A Reference Book - Class 12 is a set of two volumes, which comprehensively covers the entire Physics syllabus of Class 12th. Students who want to excel in their final examinations should study from this guidebook. Physics is an academic discipline which helps us understand how the universe behaves. It can be broadly categorised into two parts, namely Classical Physics and Modern Physics. The first branch covers laws that are highly applicable in everyday scales. Modern Physics is used to describe laws that have been developed in the early 20th century and onwards. It focuses on quantum mechanics and the interactions and behaviours of matter and energy. 2018
