Abstract : Certain class of infinite sums can be calculated analytically starting from a specific quantum mechanical problem. For simplicity we illustrate the method by exploring the problem of a particle in a box. Twofold calculation of the mean value of energy for the polynomial wave function inside the well yields even argument p of Riemann zeta and related functions. This method can be applied to a wide class of exactly solvable quantum mechanical problems.

Abstract : Elastic interactions mediated by biological membranes are an important class of sorting mechanisms used to organise proteins in living systems and with applications for biotechnology. Proteins that bind to the membrane and generate this curvature are often anisotropic and this broken symmetry yields new phenomena in their interactions. In this talk, I will discuss the many-body structures that can emerge from these elastic, quadrupole-like interactions and explore the consequences of these aggregates.

Abstract : We propose a Response Surface Methodology (RSM) based model updating approach using Frequency Response Function (FRF) curvature as the response for optimization. The optimization algorithm is based on a multi-objective function that is solved using MATLAB. The updated model is then used for identifying structural damage. The proposed approach is validated through numerical simulations on a simply supported beam and an experimental study on a free-free aluminum beam. The results demonstrate that the RSM-based model updating approach can accurately identify the location and severity of damage in structures.

Abstract : The research aim in the this article is to study the effect of magnetic field on the unsteady flow and heat transfer of an incompressible nanofluid due to a rotating disc. In addition, the flow is taken to be in a Darcy-Forchheimer porous medium. The governing set of highly non-linear PDEs are converted into set of highly non-linear ODEs using suitable similarity transformations. The system consisting of non-linear ODEs is numerically solved by the Spectral Quasi Linearization Method (SQLM). The solutions for the local skin friction along the radial direction, local skin friction along tangential direction, and the local heat transfer rate at the surface of the disc for different values of the suitable parameters are also obtained. The results of dimensionless velocity and temperature profiles are shown graphically where the values of local skin-friction coefficients and the heat transfer coefficients are presented in tabular form. A statistical analysis in the form of regression analysis is also performed to estimate the skin-friction and heat transfer coefficients.

Abstract : We present a DOLFIN/FEniCS framework for shape optimization of compact heat transfer devices consisting of periodic units. The framework relies on highly parallelized, efficient finite-element solvers for the three-dimensional periodically developed flow and heat transfer equations and their eigenvalue problems. The adjoint-based shape calculus is implemented by means of automated differentiation and operator overloading. Design constraints are incorporated through an augmented Lagrangian method. The optimized surfaces are compared with designs obtained through density-based topology optimization.
