Dynamic Analysis of Railway track and SSI effect
Abstract: The analysis of dynamic behavior of bridge structures that are subjected to moving loads has been one of the research interests in recent years. Specifically in railway bridges, Resonance occurs when the load frequency is equal to a multiple of natural frequency of the structure. Resonance vibrations have been observed in railway bridges especially subjected to High Speed Lines. They are caused mainly because of two reasons one is the …

An Experimental Study of Spherical Agglomeration of Benzoic acid And Influence of Process Parameters
Abstract: Through the process of drowning-out crystallisation in three partly miscible solvent mixtures, sphere aggregates of benzoic crystal have been successfully created. The mixture of benzoic acid, isopropyl alcohol, and bridging liquid is supplied to an agitated crystallizer with water acting as the anti-solvent. When a substance crystallises, little crystals are formed, and the bridging liquid causes the crystals to group together. Different solvents are utilised because benzoic acid crystals wettably …

Harmonics Analysis of Single Phase VSI with 5-level and 7-level Inverter
Abstract: Abstract: The conventional two-level inverter is most commonly used for AC drive systems. The inverter produces harmonics, which will cause heating of the power electronic devices as well as load and deteriorate the life of it. Thus, anyhow harmonics should be suppressed or removed, the most common or well-known method to filter out harmonics are introduction of various filters between inverter and load according to requirements. The filters are mainly …
