Abstract: Depletion of natural resources and new Environmental laws are preventing restrictive use of natural sand, thus the demand for quarry sand is increasing concrete construction. The properties of quarry sand depend upon basalt rock type from which it is derived. There is need to bring out suitable combination of natural sand and quarry sand along with other admixture to make concrete of desired performance. The present research is aimed at deciding the combination through gradation of aggregates, workability of concrete and compressive strength...........

Abstract: In India many foundries have followed conventional and manual operations. Foundry industries suffer from poor quality and productivity due to large number of process parameters combined with lower penetration of automation and shortage of skilled worker. Mould shifting, sand inclusions, poor surface finish, shrinkage, porosity, cold shut and flash are common casting defects in casting. Since casting process involves complex interaction among various parameters and operations related to metal composition, method designs, melting, pouring, shake-out, fettling and machining and hence need to improve. This Paper prescribes comprehensive review of work pertaining to process improvement techniques used for defect minimisation in casting.

Keywords: Casting design, Casting defect, Cause of defects, Yield improvement, Process improvement.

Abstract: The present study concerned with the impact of velocity slip on MHD peristaltic flow through a porous medium with heat transfer is investigated. The relevant equations of flow with heat transfer have been developed. Analytic solution is carried out under long-wavelength and small Reynolds number approximations. The expressions for the stream function, temperature and the heat transfer coefficient are obtained. Numerical results are graphically discussed for various values of physical parameters of interest.

Abstract: In this study, the effect of rotating vanes, installed on the body of the Coanda UAV is investigated both experimentally and numerically, with the aim of improving its aerodynamics performance. By constructing and testing two models of Coanda UAVs with and without axial vanes, for measuring the lift and dynamic pressure distribution on the body, 16% increase in lift is observed. In addition, a finite volume solver is utilized to investigate the flow over Coanda UAVs with and without rotating vanes. Numerical results show that the installed axial vanes on the Coanda UAV leads to increasing lift about 21%. The numerical results are in good agreement with the experiments. Overall, the results show that mounting axial vanes on the body of Coanda UAV increase lift. The consequences of installing an axial vane at the separation point of the fuselage surface on the overall lift of the Coanda UAV are discussed.

Abstract: A piled raft foundation consists of a thick concrete slab reinforced with steel which covers the entire contact area of the structure, in which the raft is supported by a group of piles or a number of individual piles. Bending moment on raft, differential and average settlement, pile and raft geometries are the influencing parameters of the piled raft foundation system. In this paper, a detailed review has been carried out on the issues on the raft foundation design. Also, the existing design procedure was explained.

Abstract: Automation and robotics are two closely related technologies. Robotics is a form of industrial automation. An industrial robot is a reprogrammable, multifunctional manipulator designed to perform verity of tasks. In recent literatures most of the robotic shoulders incorporated spherical joints representing the function of glenohumercal articulation. The design of spherical joints is complicated and range of motions is limited. So in this project the kinematic analysis of 3-limb parallel mechanisms consisting of 2URP and 1RRP chain for the shoulder of a human robot is present................

Abstract: In this work, the system of three coupled differential equations governing the generalised elastic thinwalled column buckling problem was solved by the finite Fourier sine transform method for the case of pinned ends. The boundary value problem was found to reduce to an algebraic eigenvalue eigenvector problem for which the characteristic buckling equation was found. Two cases were considered. For doubly symmetric sections, it was found that the buckling modes are uncoupled. For monosymmetric sections, it was found that one of the equations is uncoupled, while the other two are coupled..............

Abstract: This paper presents the flexural analysis using the Galerkin-Vlasov method for rectangular Kirchhoff plates with two opposite edges (y  b) clamped and the other two opposite edges (x  0, x  2a) simply supported. The plate considered is assumed homogeneous and isotropic and submitted to a uniformly distributed load, p0 over the entire plate domain. The plate variational functional is constructed using the Galerkin-Vlasov philosophy by choosing the displacement shape functions to be a product of the eigen functions of a clamped – clamped Euler – Bernoulli beam in the corresponding clamped directions and the eigen function of a simply supported Euler..............
