Keyword Detection in Text Summarization

Summarization is the process of reducing a text document in order to create a summary that retains the most important points of the original document. As the problem of information overload has grown, and as the quantity of data has increased, so has interest in automatic summarization. Extractive summary works on the given text to extract sentences that best convey the message hidden in the text. Most extractive summarization techniques revolve around the concept of indexing keywords and extracting sentences that have more keywords than the rest. Keyword extraction usually is done by extracting important words having a higher frequency than others, with stress on important. However the current techniques to handle this importance include a stop list which might include words that are critically important to the text. In this thesis, I present a work in progress to define an algorithm to extract truly significant keywords which might have lost its significance if subjected to the current keyword extraction algorithms

Instability induced pressure isotropization in a longitudinally expanding system

In two previous works [arXiv:1009.4363,arXiv:1107.0668], we studied the time evolution of a system of real scalar fields with quartic coupling which shares important features with the Color Glass Condensate description of heavy ion collisions. Our primary objective was to understand how such a system, when initialized with a non-perturbatively large classical field configuration, reaches thermal equilibrium. An essential goal of these works was to highlight the role played by the quantum fluctuations. However, these studies considered only a system confined within a box of fixed volume. In the present paper, we extend this work to a system that expands in the longitudinal direction thereby more closely mimicking a heavy ion collision. We conclude that the microscopic processes that drive the system towards equilibrium are able to keep up with the expansion of the system; the pressure tensor becomes isotropic despite the anisotropic expansion.Comment: revised version to appear in PRD, new section on comparison with hydrodynamics, 32 pages, 21 figure

India\u27s Security Environment: Towards the Year 2000

In January 1996, the U.S. War College\u27s Strategic Studies Institute and the Center for Strategic and International Studies hosted a conference on Asian Security to the Year 2000. In his presentation to the conference, Dr. Raju Thomas examined India\u27s defense perspectives and prospects. From the standpoint of national security, India\u27s post-independence history divides neatly into a turbulent first half, which included conflicts with China and Pakistan, and a relatively more stable period since 1971. That stability has been rattled by significant challenges (Kashmir, Sri Lanka, etc.), as Dr. Thomas points out. Five years ago, the collapse of the Soviet Union seemed to presage a more troubled era. Certainly, it caused as broad a reassessment of strategic policy in South Asia as elsewhere in the world. Dr. Thomas analyzes India\u27s security environment and the three levels of challenges that India confronts in this post-Cold War period--internal, conventional military, and nuclear. While the challenges in each arena are profound and interrelated, he finds considerable room for optimism that the early years of the next century will see continued stability in South Asia.https://press.armywarcollege.edu/monographs/1874/thumbnail.jp

Energy and Security in the Industrializing World

Provides detailed analyses of the related concerns of energy needs, the economy, and national security for developing countries—Argentina, Brazil, Cuba, India, Pakistan, South Africa, South Korea, and Taiwan. The essays serve to underline the dangerous problem of nuclear proliferation for several of these countries have uneasy relations with their neighbors. In their detailed reviews of these eight nations—their plans and their capabilities—the contributors have provided a valuable source for a neglected area of international affairs. Raju G.C.

Adjustable impedance, force feedback and command language aids for telerobotics (parts 1-4 of an 8-part MIT progress report)

Projects recently completed or in progress at MIT Man-Machine Systems Laboratory are summarized. (1) A 2-part impedance network model of a single degree of freedom remote manipulation system is presented in which a human operator at the master port interacts with a task object at the slave port in a remote location is presented. (2) The extension of the predictor concept to include force feedback and dynamic modeling of the manipulator and the environment is addressed. (3) A system was constructed to infer intent from the operator's commands and the teleoperation context, and generalize this information to interpret future commands. (4) A command language system is being designed that is robust, easy to learn, and has more natural man-machine communication. A general telerobot problem selected as an important command language context is finding a collision-free path for a robot

Captive breeding, developmental biology and commercial production of Dravidia fasciata- An indigenous ornamental fish of the Western Ghats of India

Ornamental fishes of the Western Ghats of India have great demand in the export market. At present these fishes are collected from the wild and exported. Hence many times, the demand could not be met due to short supply. The only remedial measure for a sustainable supply is to produce the fish in captive conditions. Unfortunately, the breeding technology for the ornamental fishes of the Western Ghats of India has not been attempted seriously till date. The present paper is almost a pioneering attempt to develop captive breeding technology for 12 prioritized species of the indigenous ornamental fishes of the Western Ghats of India. Dravidia fasciata is one of them. It is popularly known as Melon barb. It is a beautiful barb, growing to a maximum size of 80 mm. In the present paper the methodology of captive breeding of this fish is provided with the economics of its production. Melon barbs were collected from the wild and brought to the hatchery of College of Fisheries in oxygen filled plastic bags and gradually acclimatized to the captive conditions. Its size at first maturity, sexual dimorphism, and developmental biology were studied and described with photographs. The total length (TL) at first maturity for males was 50 mm (50-55 mm) and 40 mm for females (40-45 mm). A sexually mature male developed beautiful pinkish red tinge all over the body. The black bands over the body also became deeper in colour during this time. The intensity of the colour reached its maximum during the courtship activities. Male also possessed nuptial tubercles on the operculum which could be identified only by keen observation. But a sexually mature female did not develop any colour change by the onset of sexual maturity. The results of the study clearly demonstrated that D. fasciata could be successfully produced in captivity through scientific management of brooders, eggs, larvae and hatchlings. The successful development of captive breeding technology is likely to pave way towards commercialization of the technology thus leading to the sustainable export of the species
