This book introduces a new set of orthogonal hybrid functions (HF) which approximates time functions in a piecewise linear manner which is very suitable for practical applications. The book presents an analysis of different systems namely, time-invariant system, time-varying system, multi-delay systems---both homogeneous and non-homogeneous type- and the solutions are obtained in the form of discrete samples. The book also investigates system identification problems for many of the above systems. The book is spread over 15 chapters and contains 180 black and white figures, 18 colour figures, 85 tables and 56 illustrative examples. MATLAB codes for many such examples are included at the end of the book.
This book deals with a new set of triangular orthogonal functions, which evolved from the set of well-known block pulse functions (BPF), a major member of the piecewise constant orthogonal function (PCOF) family. Unlike PCOF, providing staircase solutions, this new set of triangular functions provides piecewise linear solution with less mean integral squared error (MISE). After introducing the rich background of PCOF family, which includes Walsh, block pulse and other related functions, fundamentals of the newly proposed set – such as basic properties, function approximation, integral operational metrics, etc. – are presented. This set has been used for integration of functions, analysis and synthesis of dynamic systems and solution of integral equations. The study ends with microprocessor based simulation of SISO control systems using sample-and-hold functions and Dirac delta functions.

This text presents a highly original treatment of the fundamentals of FEM, developed using computer algebra, based on undergraduate-level engineering mathematics and the mechanics of solids. The book is divided into two distinct parts of nine chapters and seven appendices. The first chapter reviews the energy concepts in structural mechanics with bar problems, which is continued in the next chapter for truss analysis using Mathematica programs. The Courant and Clough triangular elements for scalar potentials and linear elasticity are covered in chapters three and four, followed by four-node elements. Chapters five and six describe Taig’s isoparametric interpolants and Iron’s patch test. Rayleigh vector modes, which satisfy point-wise equilibrium, are elaborated on in chapter seven along with successful patch tests in the physical (x,y) Cartesian frame. Chapter eight explains point-wise incompressibility and employs (Moore-Penrose) inversion of rectangular matrices. The final chapter analyzes patch-tests in all directions and introduces five-node elements for linear stresses. Curved boundaries and higher order stresses are addressed in closed algebraic form. Appendices give a short introduction to Mathematica, followed by truss analysis using symbolic codes that could be used in all FEM problems to assemble element matrices and solve for all unknowns. All Mathematica codes for theoretical formulations and graphics are included with extensive numerical examples.

In 2019, the BJP came into power once again on the back of one of the most significant electoral mandates in recent years. Since then, the Narendra Modi-led government has seen a tumultuous few years as they have implemented far-reaching legislative changes including the Jammu and Kashmir Reorganisation Act, triple talaq, the Citizenship (Amendment) Act as well as farming laws. These laws, when implemented, caused widespread protests and upheaval across the country. While the country grappled with internal strife, it also faced challenges from its neighbours in the form of one of the most intense military stand-offs in decades after an unprovoked attack by China's People's Liberation Army at Galwan as well as a global pandemic. While the Modi government took swift steps to limit the spread of the pandemic in 2020, the second wave of COVID-19 in early 2021 hit the country hard, claiming thousands of lives. Bringing a well-researched and nuanced understanding to Modi's second term, The Midway Battle sheds light on the sociopolitical issues facing India as it continues its struggle against enemies both known and unknown, and puts into in perspective what lies ahead for the world's biggest democracy.
A report from the epicenter of the Naxalite war In its war against the Maoists, it is the Indian state that usually gets to tell its side of story. But official explanations are not meant to convey truth. Most often they attempt to cover up the reality and obscure it. The claim that only one warring side has the right to propagate its views whereas the other does not because they are projected as ‘enemy’ is questionable when we know there are two sides to any conflict and where both sides comprise our own people. In this situation of internal war, not satisfied with the knowledge offered by books and documents, Gautam Navlakha went into the heart of Bastar to get to know the Maoists first hand. This book is an account of the fortnight he spent in the guerilla zone where the Maoists run their people’s government, the Jantana Sarkar. His enquiry unflinching and his perspective critical but partisan, Navlakha succeeds in the difficult task of making the demonized human, laying bare the heartland of rebellion.

Back cover blurb Rising agricultural productivity has driven improvements in living standards for millennia. Today, redoubling that effort in developing countries is critical to reducing extreme poverty, ensuring food security for an increasing global population, and adapting to changes in climate. This volume presents fresh analysis on global trends and sources of productivity growth in agriculture and offers new perspectives on the drivers of that growth. It argues that gains from the reallocation of land and labor are not as promising as believed, so policy needs to focus more on the generation and dissemination of new technologies, which requires stepping up national research efforts. Yet, in many of the poorest nations, a serious research spending gap has emerged precisely at the time when the challenges faced by agriculture are intensifying. The book focuses on how this problem can be redressed in the public sector, as well as on reforms aimed at mobilizing new private sector actors and value chains, particularly creating a better enabling environment, reforming trade regulations, introducing new products, and strengthening intellectual property rights. On the demand side, the book examines what recent research reveals about policies to reduce the barriers impeding smallholder farmers from adopting new technologies. Harvesting Prosperity is the fourth volume of the World Bank Productivity Project, which seeks to bring frontier thinking on the measurement and determinants of productivity to global policy makers. “As rightly argued by the authors, growth in agricultural productivity is the essential instrument to promote development in low-income agriculture-based countries. Achieving this requires research and development, upgrading of universities, reinforcement of farmer capacities, removal of constraints to adoption, and the development of inclusive value chains with interlinked contracts. As important, such efforts also need to be placed within a context of comprehensive agricultural, rural, and structural transformations. However, in many countries implementation of the requisite policies has been lagging. This book, with contributions from many top experts in the field, provides the most up-to-date presentation of this argument and explains in detail how to successfully put its ideas into practice. Governments, the private sector, and civil society organizations need to study it carefully to turn the promise of agriculture for development into a reality.“ Alain de Janvry and Elisabeth Sadoulet Professors of the Graduate School, University of California at Berkeley
Gandhian Philosophy and thought on education had brought a new dimension and fundamental changes in all aspects of secondary education. He categorically emphasized on the development of social, cultural, economic, environmental and aesthetic values. He adopted the principles of ‘Learning by doing’ which will cause ‘all round drawing out of the best in child and man –body, mind and spirit’. Gandhi wanted to make our child more practical rather than depending upon the accumulation of bookish knowledge. So he emphasized on the development of 3Hs (Head, Heart and Hand) instead of 3Rs (Reading, writing and arithmetic). Gandhi rejected spoon feeding education and emphasized on the awakening of humanism and self-consciousness through self-activity and self-dependence. He advocated self-respect, self-discipline and self-honours and one’s duties and responsibilities to be achieved through education. Thus the introduction of Charkha or the spinning wheel in schools was considered the way of reviving the inner consciousness of humanity. A child receiving craft centric, purposeful, useful and meaningful education will be truly prepared for gaining self-efficiency for generating new ideas and entrepreneurial spirit concerned for quality, peace and prosperity of the humanity and for the total development of manhood. Mahatma Gandhi believed that education means, ‘all round drawing out of the best in child and man, body, mind and spirit’ The philosophical views of Gandhiji indicate that education is a means of self- supporting and self- sufficiency in life , based on truthfulness , firmness, patience and other virtues. True education makes a student an able citizen to serve the country self-less service. True education is a true knowledge of the self, soul and God. The nature of true education is defined as the formation of character.

Sir George Bernard Shaw’s contribution to the Western theatre is unparallel, and hence, is imitated, remembered and read by literature lovers even today. Over the course of his life he wrote more than 60 plays, and nearly all his plays address prevailing social problems, but each also includes a vein of comedy that makes their stark themes more palatable. In these works, Shaw examined education, marriage, religion, government, healthcare, and class privilege as primary themes of his plays. This book is an anthology of some of Shaw’s important plays, which are much talked about, and also prescribed in the English Literature syllabuses of all premier Indian and International Universities. As the title suggests, the book focuses on three important social components of that period—Politics, War and History. The plays discussed and critically analyzed are both in terms of Shaw’s interpretation of his times, and the author’s research on the subject. This book is suited for the undergraduate and postgraduate students of English. Besides, the students doing research work in Shaw’s plays will be benefitted reading this book.

Humans are exposed daily to low concentrations of metals that are released into the environment by both natural and industrial processes. Environmental Metal Pollutants, Reactive Oxygen Intermediaries and Genotoxicity: Molecular Approaches to Determine Mechanisms of Toxicity examines concerns about the acute and/or chronic exposure of humans to concentrations of these metals that are below the threshold levels established by various federal regulatory agencies. Some of these metals are accumulated in various tissues and over time this may result in the accumulation of a significant body burden. This could increase the risk of developing a variety of diseases later in life, at a time when thresholds for such effects may already be reduced by the processes of aging. Such possibilities could only further compromise the quality of life in the elderly population and could contribute to the rising cost of health care in this country. Studies that have been conducted to determine the possible risks associated with exposure to relatively non-toxic concentrations of environmental metals have been hampered by a lack of appropriate models and a lack of funding. It has also been difficult for researchers to demonstrate a correlation between the exposure of humans or animals to low concentrations of environmental pollutants and disease. This book examines recent technological advances in the areas of molecular biology, biochemistry, and computer-enhanced image analyses that provide researchers with the tools to begin elucidating the genotoxic effects of environmental metal pollutants and the mechanisms by which these metals cause DNA damage. Environmental Metal Pollutants, Reactive Oxygen Intermediaries and Genotoxicity: Molecular Approaches to Determine Mechanisms of Toxicity presents data that demonstrate that certain environmental metal pollutants are genotoxic. The authors describe the role of reactive oxygen intermediates in causing the DNA damage induced by environmental metal pollutants and discuss their possible role in human disease.
The weak or non-conventional hydrogen bond has been subject of intense scrutiny over recent years in several fields, in particular in structural chemistry, structural biology, and also in the pharmaceutical sciences. There is today a large body of experimental and theoretical evidenceconfirming that hydrogen bonds like C-H...O, N-H...pi, C-H...pi and even bonds like O-H...metal play distinctive roles in molecular recognition, guiding molecular association, and in determining molecular and supramolecular architectures. The relevant compound classes include organometalliccomplexes, organic and bio-organic systems, and also DNA and proteins. The book provides a comprehensive assessment of this interaction type, and is of interest to all those interested in structural and supramolecular science, including fields as crystal engineering and drug design.
