Abstract: This paper presents a new GA based model to analyze the steady state performance of the self-excited induction generator (SEIG) under unbalanced load and excitation. The proposed model is based upon the load decoupled approach using symmetrical component theory. The simulated results as obtained using proposed model are compared with experimental results on a test machine. Close agreement with the experimental results proves the effectiveness of GA based model and …

Buckling and vibration of plates by hyperbolic shear deformation theory
Abstract: Hyperbolic shear deformation theory is used to determine the natural frequencies and buckling loads of elastic plates. The theory takes account of transverse shear effects and hyperbolic cosine distribution of the transverse shear strains through the thickness of the plate, hence it does not require shear correction factor. Governing equations are derived from the principle of virtual work. The closed-form solution of a simply supported plate subjected to in-plane loading …

Pressure Swing Adsorption Process for Reduction of Argon-41 Release from Nuclear Reactor Exhaust Systems
Abstract: In several nuclear reactors, huge quantity of air (in the order of 10,000 cmh) is continuously passed to cool the calandria vault. This results in high radiation field due to argon-41. It is necessary to isolate and recover argon from these environments, which can bring down the activity release to the atmosphere in attaining ALARA principle. Pressure swing adsorption (PSA) technique has been employed by combining molecular sieves 5A (MS5A) …

Vibration Characterization of SiCp and Fly Ash Dispersion Strengthened Aluminium 5083 Composites
Abstract: The requirements of current day engineering applications is based on high damping materials which exhibit superior mechanical properties as well as high damping limit for vibrations. In structures made of metals and composites, it is difficult to achieve high damping limit and great mechanical properties at the same time. This is majorly due to the infinitesimal systems that result in "microscopic mechanisms and parameters affecting the mechanical strength". However, to …
