Wide parameter search for isolated pulsars using the Hough transform

We use the Hough transform to analyze data from the second science run of the LIGO interferometers, to look for gravitational waves from isolated pulsars. We search over the whole sky and over a large range of frequencies and spin-down parameters. Our search method is based on the Hough transform, which is a semi-coherent, computationally efficient, and robust pattern recognition technique. We also present a validation of the search pipeline using hardware signal injections.Comment: Presented at GWDAW-9 in Annecy, France (Dec. 2004). 11 pages, 5 Figures.

Capture process and prospects in marine island fishery with emphasis on trade: a typical paradigm of underutilized resources in Bay Islands

In economics the term ‘trade-off’ is expressed as opportunity cost, referring to the most preferred alternative given up. A trade-off, then, involves a sacrifice that must be made to obtain a certain product, rather than other products that can be made using the same required resources. For a person going to a basketball game, its opportunity cost is the money and time expended, say that would have been spent watching a particular television program (Wikipedia). Another key word is ‘sustainable development’. Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs (World Commission on Environment and Development). Sustainable development was added as one of the general objectives of the World Trade Organization when it was established in 1994

Oceanographic features and abundance of the pelagic fisheries along the west coast of India

The results of a study on the hydrographic properties such as temperature, salinity and Sigma-T (density) content of the surface waters along the west coast of India collected during the cruises of R. V. Varum and other vessels are presented e,s an average distrbution of the factors month-wise for each degree square. This has been used to investigate the relationship of the hydrographic conditions with the pelagic fishery landings such as thpsp of the oil sardine and the Indian mackerel month-wise. The importance of the coastal phenomena like upwelling and sinking in relation to the fishery landings is pointed out

Is current forest landscape research approaches providing the right insights? Observations from India context

One of the major challenges in the current scenario for ecological conservation is to quantify the forest landscape in its spatio-temporal domain and understand further implications of those. While the detailed study of the forest ecosystems may provide insights into biodiversity, carrying capacity and productive nature, most of the studies are restricted to single time/event inventory and focused on assessment of tree diversity patterns. Through the adoption of geospatial technologies like remote sensing and Geographical Information System (GIS), though forest monitoring has been possible, the linkages to the biodiversity distribution and its patterns are still at an empirical level, thus supporting broad measures of protection and preservation without accounting for the local/regional variability.Towards this the paper discusses the lacuna in the current landscape research approaches in Indian scenario. Presents a framework to analyze the landscape structure at the, micro, meso and macro levels. Emphasize the need for the collection of spatio-temporal field data to analyze the change in biodiversity and their linked entities. The paper suggests the need for development of long term ecological area networks to understand the ecological processes, making the data open and improve collaborations among the organizations working in the similar domain to enhance the impact of the research works
