Abstract: The Sun based vitality is rapidly progressing as an essential method for renewable energy resources. More vitality is obtained by tracking the solar panel, by placing the panel remains related to the sun at a right edge to the beams of light. It illustrates the point of interest of outline and development of a model for solar tracking system with two degrees of opportunity, which recognizes the sunlight by means of photocells........

Abstract: Signal Processing approach is proposed to highlight the features of speech in degraded signal. The approach is based on Single Frequency Filtering (SFF), where the amplitude envelope of the signal is obtained at each frequency with high temporal and spectral resolution. So this method exploit the fact that speech has high SNR region at different frequency and at different time .Here three methods are discussed and the spectral and temporal resolution is compared ........

Abstract: Biometric based Human Information and Voting is a peculiar process to verify and store the whole details of any person only through his fingerprint. Then it also allows the person to cast his vote as an application model. Here the coding part is done in a software named LabVIEW which a graphical programming language where the execution is done in sequential way. MyDAQ is a Data Acquisition Device used to implement the whole process.
