Abstract
In this paper, the relation of static and different domino designs is reviewed on the basis of different factors for the betterment of modern communication services. Noise immunity, leakage and speed are the three most important factors which is considered, while designing high speed wide fanin logic gates. Improving the noise immunity and reducing the leakage current without affecting the speed for logic gates is a challenging task for the circuit designs. In this work the speed performance of various domino logic circuit designing styles, the design of logic gates has been reviewed by analyzing key parameters such as normalized unity-noise-gain (UNG), power consumption, threshold fluctuations and delay

Abstract
The numerical simulation is based on the detailed combustion reaction which consisting of 12- species and 27 reactions. A Grid adaptation technic has been used in order to resolve the detonation front of the structured grid. Very good comparisons are obtained for the NO and NOx emissions due to various chemical reactions in the mixing case. In this research, in viscid, k-e and k-w-SST turbulence model has been performed and a better result are obtained with in viscid turbulence model than the other two turbulence models in its class.From this research it is clear that NOx formation in pulse detonation engine can be minimized either by operating with lean or rich mixtures or by using small tubes for combustion. The results indicate that the simple chemical reaction is adequate to describe the H2-air kinetics in the pulse detonation engine combustor. Finally, these numerically simulated results were validated with the previously published literature and NASA-CEA (National Aeronautics and

Abstract
Structural strengthening of reinforced concrete (RC) structural elements has become essential due to several reasons, namely, (i) to meet the up-gradation of existing structures due to the infrastructure development (ii) excessive deflection, cracking, inadequate ultimate strength (iii) to carry higher permissible loads (iv) design faults (v) poor construction practices (vi) poor durability etc. Sometimes, structures/components may be subjected to overloads, which will cause more cracking and reduction in stiffness/strength. There are several popular techniques, namely, externally bonded steel plates, concrete jacketing, fibre reinforced laminates or sheets, external prestressing/external bar reinforcement technique are available to address repair and retrofitting of RC structural components. Recently, cementitious based material, namely, ultra high strength concrete or ultra high performance concrete is being used as strengthening material. Each technique/retrofit material has its own

Abstract
A particle velocity contour, pressure and wall shear stress on the centre line and two distinct point on the surface of wall boundaries within the micro-shock tube has been obtained to describes the different phenomenoninside driver and driven section of the tube. Therefore, it is highly required to improve the performance of micro-shock tube in engineering and medical fields,it is significantly important to investigate shock waves and particle-gas flows induced by micro-shock tubes. Even though shockwaves and multiphase flows discharged from micro-shock tubes have been studied for several decades, the characteristics of unsteady particle- gas flows are not well known to date. In the present studies, 2D micro-shock tube models were used fornumerical simulations. Discrete phase method (DPM) was used to simulate unsteady particle-gas flows and the discrete random walk model was chosen to record the unsteady particle tracking. The results obtained from numerical simulation has been compar
