This book shows how a conventional multi-layered approach can be used to control a snake robot on a desired path while moving on a flat surface. To achieve robustness to unknown variations in surface conditions, it explores various adaptive robust control methods. The authors propose a sliding-mode control approach designed to achieve robust maneuvering for bounded uncertainty with a known upper bound. The control is modified by addition of an adaptation law to alleviate the overestimation problem of the switching gain as well as to circumvent the requirement for knowledge regarding the bounds of uncertainty. The book works toward non-conservativeness, achieving efficient tracking in the presence of slowly varying uncertainties with a specially designed framework for time-delayed control. It shows readers how to extract superior performance from their snake robots with an approach that allows robustness toward bounded time-delayed estimation errors. The book also demonstrates how the multi-layered control framework can be simplified by employing differential flatness for such a system. Finally, the mathematical model of a snake robot moving inside a uniform channel using only side-wall contact is discussed. The model has further been employed to demonstrate adaptive robust control design for such a motion. Using numerous illustrations and tables, Adaptive Robust Control for Planar Snake Robots will interest researchers, practicing engineers and postgraduate students working in the field of robotics and control systems.
To begin afresh, after her broken marriage, Saoli returns to India and starts living in prembajar at the house her grandfather had bought from Bitasta’s father. While cleaning the house, Saoli comes across an old diary, perhaps belonging to Bitasta’s mother, Panchali. The Diary has a very cryptic poem written in dactylic hexameter, the archaic meter of the ancient Greek epics. Aware of the fact that Sairandhri didn’t let her son, Parush, marry Bitasta, even though sairandhri and bitasta’s mother were best of friends, saoli gets in touch with the reckless parush, recently accused in a high-profile IP theft case in the US. As Parush tells Saoli about his heedless and shattered life, his unrequited love affair with Bitasta, his lifelong hatred for his mother and his topsy-turvy corporate career in the US, Saoli unearths the darkest secrets hidden in the cryptic poem all this long. Why didn't Sairandhri want Parush to marry Bitasta? Why was Bitasta the only person she wished to see on her death-bed? Why had she been nothing more than a beautiful but lifeless mural at home? The cryptic poem has the answers. Join Saoli and Parush in their journey to decode the past and discover their real identities, where love can never be chained by stereotypes. It’s time to set love free!
This book comprehensively reviews various omics approaches like genomics, proteomics, transcriptomics, and metabolomics for understanding pulmonary disease at molecular and systems levels. The initial chapters present the pathogenesis of major pulmonary diseases, namely, obstructive diseases, restrictive diseases, vascular diseases, infectious diseases, and neoplastic carcinoma. The book chapters provide current information about the role of the microbiome and applications of medical imaging, bioinformatics tools, and databases for diagnosis and designing treatment strategies against complex lung diseases. Further, the book discusses omics technologies to identify biomarkers for the early diagnosis and prognosis of pulmonary diseases. Finally, the book elucidates the multi-omics approaches and data integration using mathematical modeling for insights into the disease etiology towards improving the prognostics and predictive accuracy of disease phenotypes.
This book is an anthology of essays, poems and one play by Chattopadhyay culled over a decade of writing. It delves into popular culture, literature, language, society, cinema, spirituality and matters of faith. It presents an alternate view on contemporary life and customs seen through the prism of his personal experience. The essential spirit is one of enquiry, and it deliberately steers clear of dogma. The text makes pertinent observations based on experience, study and interpretation of phenomena but does not propound any absolute theory. It is an informed Indian’s point of view in 2019. The book is reader-friendly with dollops of humor. Yet the discerning reader can also find insights from the subtly layered subtexts that propound the subaltern thought, albeit in a curious way. This book is essentially about myriad Indian thoughts, the mosaic of a complex civilization and an equally complex thought, constantly insightful and often bathetic and self-deprecatory. The nebula of Sudipto’s The Day I Stopped Lying is immense and immeasurable, forever expanding its arms in all directions… - Brahmanand S Siingh, National Award-winning filmmaker, author and speaker, based out of Mumbai. I’ve always wanted him to go, beyond movies into the world of literature because that where he truly belongs. I am so glad and proud that he has finally taken the plunge with his outstanding debut. - Sanjay Gupta, the veteran film-maker with superhits like Kaante, Zinda, Musafir and Kaabil to his credit

The first edition of Theory of Valuation is a collection of important papers in the field of theoretical financial economics published from 1973 to 1986, and original accompanying essays contributed by eminent researchers including Robert C Merton, Edward C Prescott, Stephen A Ross, and Joseph E Stiglitz. Since then, with the perspective of major theoretical strides in the field, the book has more than fulfilled its original expectations. The realization that it remains today a compendium of classic articles and a must-read for any serious student in theoretical financial economics, has prompted the publication of a new edition. This second edition presents a summary statement of significant research in theoretical financial economics for both the specialist and non-specialist financial economist. It also provides material for PhD-level courses covering valuation theory, and elective reading for advanced MasterOCOs and undergraduate courses. In addition to reproducing the original contributions, this edition includes the seminal paper by Edward C Prescott and Rajnish Mehra, OC Recursive Competitive Equilibrium: The Case of Homogeneous Households, OCO originally published in Econometrica in 1980.

From the late eighteenth century, Calcutta, first city of the British Empire, has been a hub of intersecting ideas and movements of change. Nowhere did the restless currents of history play themselves out more graphically than in the composite art of theatre and performance. This pioneering study of the history of Bengali theatre looks at the plays mounted in the city in the eighteenth and nineteenth centuries and their reception. It goes on to study the cultural efflorescence known as the 'Bengal Renaissance' and the subsequent politicization of a theatre imbued with ideas of nationalism and social reform, with a particular focus on the complex and problematic issue of the place of women in theatre.
