Abstract

In this study, shape optimisation of steel pedestals are attempted using neural network. Considering different geometrical parameters, finite element analyses of pedestals are carried out. Using these results, a back propagation neural network is trained. Successfully trained networks is further used for shape optimisation of newer problems. Thus optimised pedestals are further validated with finite element analyses counterparts and found to be in close match.

Abstract

Numerical analysis of Partial Differential Equations (PDE's) of the solid mechanics using Finite Element Method (FEM) is very popular. One issue which is haunting the finite element solution is the computer time. Finite Element Analysis (FEA) using fine mesh and large number of nodes consumes lot of solution time. To overcome this difficulty, a hybrid Neuro-FEM is proposed. FEM solutions considering coarse mesh is used for training neural networks which is further employed for finer predictions. The proposed methodology is successfully employed on a cantilever beam problem.

Abstract

The rise of health psychology has been strongly influenced by the traditional paradigm and its contribution cannot be denied in relieving health related problems. However, along with enjoying the success of the traditional paradigm in health psychology we need to remind ourselves the goal of health psychology and to be cognizant of its role in achieving that goal. Health psychology, in an eager rush to establish itself as a scientific discipline and to show its compliance to the scientific community, has lost and ignored the voices of people being studied. The paper is aimed to present a critical review of health psychology by drawing a parallel between health psychology and biomedical modal. It also tries to explicate how the lacuna created by health psychology can be filled by shifting its paradigmatic orientation, i. e. by shifting its focus from intra psychic processes to the socio-cultural realities and subjecivities of people being studied and to promote social justice and diversity.
