Analysis of Fingerprint Image Enhancement by Different Methods
Abstract: The fingerprint enhancement method using directional filter/Rotational filter is effective in both dry fingerprint images and wet fingerprint images. It removes noise in between the ridge and filling the white hole in the ridge. This leads to decrease the False Acceptance Rate (FAR) and False Rejection Rate (FRR), in fingerprint minutiae extraction. In fingerprint image enhancement, for the image matching there are used various filters likes Gabor filter, FFT filter …

Square Wave Pulsed Electrodeposition of Chromium from Deep Eutectic Solvent (DES) Based on Choline Chloride
Abstract: Electrodeposition of chromium from hexavalent chromium ion is very toxic, carcinogenic, not environmentally benign, cathodic efficiency is low, and the quality of coating is very poor (due to H2 evolution). Ambient temperature Deep Eutectic Solvent (DES) can be formed by reacting choline chloride (HOC2H4 (CH3)3Cl) with metal salts. These low cost DES are not sensitive to air and moisture and have good electro-conductivity and they do not have vapour pressure. …

Analysis of THD in Voltage Source Inverter with Constant Current Controller for Solar PV Cell
Abstract: A common method in the study of voltage source inverters is the hypothesis of a voltage-type input source even in the case of renewable energy (RE). When a converter is supplied by an RE, such as a photovoltaic (PV) generator, the dc-link voltage is usually controlled by the converter with closed loop to extract maximum power from the source. The main aim of the paper is to analyze the total …
