Reduction of Pollutant for SI Engine Using Argon and Oxy-hydrogen
Abstract: Reducing the emission associated with oil combustion is gaining increasing interest worldwide. Due to their dangerous effects on human health, vegetation and climate, various pre-combustion, in-cylinder and post combustion techniques have been tried for their abatement. The combustion of a hydrocarbon fuel with air produces mainly carbon dioxide(CO2) and Water(H2O). However, internal combustion engines are not perfectly efficient, so some of the fuel is not burned, which results in the …

Optimization of Operational Parameters for Production of Bio-ethanol from Red Gram Straw
Abstract: AbstractBio-alcohol is a neat and cleaner source of energy, which could be obtained from locally available biomass. However, the complex structure of lignocellulose in biomass makes a primary protective barrier that prevents cell destruction. In order to break down this structure for the conversion of biomass to fuel ethanol, the cellulose and hemicellulosic materials must be broken down to corresponding monomers (sugars). It could be done easily with acid hydrolysis …

Experimental Demonstration on the Leakage-Free Surface-Driven Capillary Flow of Red Dye
Abstract: In this work, two individual SU-8 based glass microfluidic devices are fabricated by the maskless lithography and indirect bonding technique. Commercially available red-colored food dye is used as the working liquid. Microfluidic leakage is observed between the glass lid and SU-8 based microchannel substrate due to the improper indirect bonding technique. Leakage-free surface-driven capillary flow is observed due to the proper indirect bonding technique. CMOS camera is used to capture …

Centralized Controller Design Of Two-Input Two-Output Process Using SISO Design Techniques
Abstract: In two-input two-output (TITO) systems, interactions should be appropriately accounted for proper input-output pairing. Pairing plays an important role, where the wrong pairing can lead to unstable systems, even each one of the loop is stable individually. In this paper interactions of TITO time-delay systems are quantified using the gramian based interaction measures. Using this pairing problem is addressed for TITO systems and a multivariable controller is designed using siso …
