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)
The objective is to design and implement an automated Temperature control system using embedded system design in order to control the temperature of a system. As such, it is vital that those in engineering fields understand the technologies associate with this area. My paper will include the design and construction of a microcontroller-based automated(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)
