This research monograph is in some sense a sequel to the author's earlier one (Power System Stability, North Holland, New York 1981) which devoted cons- erable attention to Lyapunov stability theory, construction of Lyapunov fu- tions and vector Lyapunov functions as applied to power systems. This field of research has rapidly grown since 1981 and the more general concept of energy funct ion has found wide spread application in power systems. There have been advances in five distinct areas (i) Developing energy functions for structure preserving models which can incorporate non-linear load models (ii) Energy fu- tions to include detailed model of the generating unit i. e. , the synchronous machine and the excitation system (iii) Reduced order energy functions for large scale power systems, the simplest being the single machine infinite bus system (iv) Characterization of the stability boundary of the post-fault stable eQui- brium point (v) Applications for large power networks as a tool for dynamic security assessment. It was therefore felt appropriate to capture the essential features of these advances and put them in a somewhat cohesive framework. The chapters in the book rough ly fo llow this sequence. It is interesting to note how different research groups come to the same conclusion via different reas- ings.
Every Hindu and anyone who has some interest in Hindu scriptures should read this book. It reveals hidden facts of quantum physics from original texts such as the Linga Purana, Shiva Purana, etc. These scriptures have been misrepresented for more than 200 years by the enemies of Hindus. All parents should read this knowledge-treasure and share it with their children. Guruji Sundara Raj Anantha has revealed esoteric secrets that proof Hindu shastra-s are science-based. The scientific facts found in our shastra-s are the earliest and oldest written records in the world. The depth of knowledge contained in these shastra-s are way beyond its time. It is an astounding fact that without the availability of modern instruments, the Siddha-s, Yogi-s, and Guru-s were so advanced scientifically in ancient times. How is this possible? This book will make everyone proud of being a Hindu.
This is an inspiring biography of noted paraplegic Indian athlete Malathi K. Holla. A Different Spirit captures the trials and turbulences of Malathi, who despite undergoing 33 surgeries and many setbacks in her life, never gave up and won over 300 medals for India in various international championships. Written by leading defence journalist and blogger Dr Anantha Krishnan M, A Different Spirit is being hailed by the media as one of the most inspiring stories of our times. A Different Spirit is the first project of Bangalore-based Inspired Indian Foundation (IIF), a writers' movement backing unsung heroes. As the founder President of IIF, the author has pledged the royalties from the book to support the cause of unsung heroes. The IIF hopes to raise funds through the sales of A Different Spirit (now into its sixth edition), for Malathi's dream of building a permanent structure for Mathru Foundation, a home for paraplegic children.
