This book is the fruition of four decades of teaching Mechanical Engineering subjects including Quality Engineering, Total Quality Management, and Principles of Management for the Bachelor and Master degree courses in Engineering at Annamalai University, and then in Arunai Engineering College, Tiruvannamalai, by the author. Frank and continual feed back from the distinguished students and esteemed colleagues of the author obtained during teaching, enthused him in shaping this book into a valuable present to the scholars pursuing engineering.This book amply covers the updated syllabus of Professional Ethics by Anna University. Besides the basic human values, Codes of ethics of major Indian professional societies, detailed risk analysis with illustrative examples are included. Further, twenty four crisp case studies covering a wide spectrum of topics in Professional Ethics, short-answer questions, long-answer questions with hints have been appended to sustain the interest of the engineering students. Besides the prescribed syllabus, ethics-related topics such as Social Acceptability SA 8000, Safety System OHSAS 18001 and Engineer-Manager interactions have also been explained.

Over the past two decades, there has been a huge amount of innovation in both the principles and practice of operating systems Over the same period, the core ideas in a modern operating system - protection, concurrency, virtualization, resource allocation, and reliable storage - have become widely applied throughout computer science. Whether you get a job at Facebook, Google, Microsoft, or any other leading-edge technology company, it is impossible to build resilient, secure, and flexible computer systems without the ability to apply operating systems concepts in a variety of settings. This book examines the both the principles and practice of modern operating systems, taking important, high-level concepts all the way down to the level of working code. Because operating systems concepts are among the most difficult in computer science, this top to bottom approach is the only way to really understand and master this important material.
