A study of Indian foreign policy under Jawaharlal Nehru, concentrating on the fundamental questions of war and peace. Looks at Nehru's handling of the disputes over the fate of Junagadh, Hyderabad and Kashmir in 1947-48; the refugee crisis in East and West Bengal in 1950; the Kashmir crisis in 1951; and the boundary dispute with China 1949-62.

MICROWAVE INTEGRATED CIRCUIT COMPONENTS DESIGN THROUGH MATLAB® This book teaches the student community microwave integrated circuit component design through MATLAB®, helping the reader to become conversant in using codes and, thereafter, commercial software for verification purposes only. Microwave circuit theory and its comparisons, transmission line networks, S-parameters, ABCD parameters, basic design parameters of planar transmission lines (striplines, microstrips, slot lines, coplanar waveguides, finlines), filter theory, Smith chart, inverted Smith chart, stability circles, noise figure circles and microwave components, are thoroughly explained in the book. The chapters are planned in such a way that readers get a thorough understanding to ensure expertise in design. Aimed at senior undergraduates, graduates and researchers in electrical engineering, electromagnetics, microwave circuit design and communications engineering, this book: • Explains basic tools for design and analysis of microwave circuits such as the Smith chart and network parameters • Gives the advantage of realizing the output without wiring the circuit by simulating through MATLAB code • Compares distributed theory with network theory • Includes microwave components, filters and amplifiers S.

Computer Science and Operations Research continue to have a synergistic relationship and this book represents the results of the cross-fertilization between OR/MS and CS/AI. It is this interface of OR/CS that makes possible advances that could not have been achieved in isolation. Taken collectively, these articles are indicative of the state of the art in the interface between OR/MS and CS/AI and of the high-caliber research being conducted by members of the INFORMS Computing Society.

This edited book serves as a companion volume to the Seventh INFORMS Telecommunications Conference held in Boca Raton, Florida, March 7-10, 2004. The 18 papers in this book were carefully selected after a thorough re­ view process. The research presented within these articles focuses on the latest methodological developments in three key areas—pricing of telecommunica­ tions services, network design, and resource allocation—that are most relevant to current telecommunications planning. With the global deregulation of the telecommunications industry, effective pricing and revenue management, as well as an understanding of competi­ tive pressures are key factors that will improve revenue in telecommunica­ tions companies. Chapters 1-5 address these topics by focusing on pricing of telecommunications services. They present some novel ideas related to pricing (including auction-based pricing of network bandwidth) and modeling compe­ tition in the industry. The successful telecommunications companies of the future will likely be the ones that can minimize their costs while meeting customer expectations. In this context the optimal design/provisioning of telecommunication networks plays an important role. Chapters 6-12 address these topics by focusing on net­ work design for a wide range of technologies including SONET, SDH, WDM, and MPLS. They include the latest research developments related to the mod­ eling and solving of network design problems. Day-to-day management/control of telecommunications networks is depen­ dent upon the optimal allocation of resources. Chapters 13-18 provide insight­ ful solutions to several intriguing resource allocation problems.

Telecommunications Modeling, Policy, and Technology Examines the newer and emerging models of telecommunications technology that play instrumental roles in providing international economic and societal interconnectivity. Advancing technology in the field imposes the need to develop new models to solve complex planning and decision making problems. The global, national, and local societal impact of the technology necessitates careful analysis of telecommunications policy at all of these levels. The book explores natural output of the new technical developments and applications with selective chapter treatment on novel business models to fill the emerging technical and business needs.

Covers the entire range of developments in the operational and research use of radar for meteorological applications, such as aviation, precipitation measurement and hydrology, tropical cyclone observation and forecasting and wind profiling. The book emphasises the operational aspects of radar meteorology. It also traces the evolution of the subject including older technologies still in use in some countries, which will help students assimilate the basic principles. A feature of the book is a detailed treatment of tropical cyclones as observed by radar, a topic of great interest in tropical countries. This work is suitable as a text or reference book for professional radar meteorologists, professional training courses for personnel of meteorological services, and for university courses in atmospheric science and meteorology.

This text represents the state of the art of applying operations research techniques and solutions across a broad spectrum of telecommunications problems and implementation issues. The first three chapters of the book deal with the design of wireless networks, including UMTS and Ad-Hoc networks. Chapters 4-6 then deal with the optimal design of telecommunications networks. Chapters 7-10 analyze traffic flow in telecommunications networks, focusing on optimizing traffic load distribution and the scheduling of switches under multi-media streams and heavy traffic, then chapters 11 -14 deal with telecommunications network management, examining bandwidth provisioning, admission control, queue management, dynamic routing, and feedback regulation in order to ensure that the network performance is optimized. Finally, chapters 15-16 deal with the construction of topologies and allocation of bandwidth to ensure quality-of-service. The contributions to the volume were carefully selected after a thorough review process.

The research presented in Telecommunications Planning: Innovations in Pricing, Network Design and Management focuses on the latest methodological developments in three key areas -- pricing of telecommunications services, network design, and resource allocation. These three elements are most relevant to current telecommunications planning. The first five chapters cover global deregulation of the telecommunications industry, effective pricing and revenue management, as well as an understanding of competitive pressures are key factors that will improve revenue in telecommunications companies. The next seven chapters outline what successful telecommunications companies of the future will need to do in order to minimize their costs and still meet customer expectations. The final six chapters provide insightful solutions to several resource allocation problems.

Theoretical research and practical applications in the ?eld of vehicle routing started in 1959 with the truck dispatching problem posed by Dantzig and Ramser [1]: ?nd the “. . . optimum routing of a ?eet of gasoline delivery trucks between a bulk terminal and a large number of service stations supplied by the terminal. ” Using a method based on a linear programming formulation, their hand calculations produced a near-optimal solution with four routes to aproblemwithtwelve service stations. The authorsproclaimed:“Nopractical applications of the method have been made as yet. ” In the nearly 50 years since the Dantzig and Ramser paper appeared, work in the ?eld has exploded dramatically. Today, a Google Scholar search of the words vehicle routing problem (VRP) yields more than 21,700 entries. The June 2006 issue of OR/MS Today provided a survey of 17 vendors of commercial routing software whose packages are currently capable of solving average-size problems with 1,000 stops, 50 routes, and two-hour hard-time windows in two to ten minutes [2]. In practice, vehicle routing may be the single biggest success story in operations research. For example, each day 103,500 drivers at UPS follow computer-generated routes. The drivers visit 7. 9 million customers and handle an average of 15. 6 million packages [3].
