| The results of the performance and emission of a variable compression ratio ignition engine (vertical single cylinder) by using Jatropha ethyl ester blends with diesel fuel at two levels of compression ratio (16.5:1 and 18.5:1) have been presented in this paper. The fuel samples were prepared by blending Jatropha ethyl ester with diesel in the composition of 0:100, 10:90, 20:80, 30:70 and 40:60 (%). Results indicated that Brake thermal efficiency for all biodiesel blends was more as compared to diesel. Brake thermal efficiency increased with the increase in load and also increased with the increase in compression ratio. Brake specific fuel consumption in case of blends was more as compared to diesel. Brake specific fuel consumption decreased with the... |

| Precision agriculture is a methodology to identify and exploit variability within an agricultural field. In India, a yield is measured during marketing of harvested crop and as a gross yield of the land owned by the farmer. The yield monitor mounted over grain combine harvester measures and records information such as grain flow, grain moisture, area covered and location. An automated yield monitoring system consisting of a yield sensor, global positioning system (GPS), field computer with custom software was mounted on a self propelled indigenous grain combine harvester for real-time crop yield mapping along with moisture data. By means of optical sensors (light emitter and detector), the height of the grain on the elevator paddles was measured and... |
