Butt welding of austenitic stainless steel 304 plates was carried out using an electron beam. Experiments were conducted for various combinations of input process parameters determined according to central composite design. Three input parameters, namely accelerating voltage , beam current, and welding speed were considered during the experiments. The(More)
Captured imagery by terrestrial mobile mapping systems proved to be an effective tool for the extraction of road and roadside features for a variety of transportation activities. Among these features, road signs are important for several applications such as navigation and driver's alert systems. Manual extraction of road signs from thousands of imagery is(More)
Information on inoculum load and diversity of native microbial community is an important prerequisite for crop management of microbial origin. Azospirillum has a proven role in benefiting the maize (Zea mays) crop in terms of nutrient (nitrogen) supply as well as plant growth enhancement. Bihar state has highest average national maize productivity although(More)
Electron beam butt welding of stainless steel (SS 304) and electrolytically tough pitched (ETP) copper plates was carried out according to central composite design of experiments. Three input parameters, namely accelerating voltage, beam current and weld speed were considered in the butt welding experiments of dissimilar metals. The weld-bead parameters,(More)
The energy resolution of the barrel part of the CMS Electromagnetic Calorimeter has been studied using electrons of 20 to 250 GeV in a test beam. The incident electron's energy was reconstructed by summing the energy measured in arrays of 3×3 or 5×5 channels. There was no significant amount of correlated noise observed within these arrays. For electrons(More)
Acknowledgements The CMS Computing Group gratefully acknowledges the contributions of technical staff throughout the world who have been involved in the design, operations and analysis of the computing challenges that have led us to this TDR. The CMS computing technical design has been developed in cooperation with our colleagues in the Worldwide LHC(More)
Segmentation of satellite images is an important issue in various applications. Though clustering techniques have been in vogue for many years, they have not been too effective because of several problems such as selection of the number of clusters. This proposed work tackles this problem by having a validity measure coupled with the new clustering(More)
