In the field of machine vision, camera calibration refers to the experimental determination of a set of parameters which describe the image formation process for a given analytical model of the machine vision system. An accurate, reliable calibration procedure is essential for most industrial machine vision applications including mechanical metrology, robot(More)
Using observations and long term simulations of an ocean-biogeochemical coupled model, we investigate the biological response in the southern subtropical Indian Ocean (SIO) associated with Ningaloo Niño and Niña events. Ningaloo events have large impact on sea surface temperature (SST) with positive SST anomalies (SSTA) seen off the west coast of Australia(More)
Wireless Network Control System (WNCS) has received considerable attention with advances in control and communication technologies. This paper presents the stability analysis of real time PI controller design and Smith Predictor control strategy for the compensation of assumed delay in the plant. Mathematical modelling of the plant is obtained and the(More)
In this paper, the characteristics of organic bulk heterojunction solar cells have been designed and modeled using MATLAB R2010a version. Here, organic solar cell is considered as a diode and an equivalent circuit is developed with series and shunt resistances to obtain the I-V characteristics of the model. Non-linear equations are obtained in by solving(More)
The antiulcer activity of ethanolic extract of Calotropis gigantea R.Br leaves (EECG) was investigated in pylorus ligation and ethanol induced ulcer models in experimental rats. In both models the common parameter determined was ulcer index. Ethanolic extract of Calotropis gigantea at a dose of 150 and 300mg/kg produced significant inhibition of the gastric(More)
