Rh(I) complexes of S-triazines and azobenzene were found to be very efficient towards the catalytic hydrogenation of alkenes, alkynes at normal pressure, and at room temperature. Reduction of aromatic nitrocompounds, benzaldehyde, and benzil were observed in appreciable amounts only at high pressure and at high temperature. No diminished catalytic activity was observed even after 6-8 repeated catalytic runs. Profound effect was observed on the rate of reduction in presence of extra ligand without affecting the nature of yield, both under normal and high pressure conditions. Kinetics was studied. Mechanism has been proposed and rate equation has been derived. Copyright © Taylor & Francis Group, LLC. Source

In this paper, we constitute a homotopy algorithm basically extension of homotopy analysis method with Laplace transform, namely q-homotopy analysis transform method to solve time- and space-fractional coupled Burgers' equations. The suggested technique produces many more opportunities by appropriate selection of auxiliary parameters ℏ and n(n≥1) to solve strongly nonlinear differential equations. The proposed technique provides ℏ and n-curves, which describe that the convergence range is not a local point effects and finds elucidated series solution that makes it superior than HAM and other analytical techniques. © 2016 Faculty of Engineering, Alexandria University.

In this paper, two efficient analytic techniques namely the homotopy analysis transform method (HATM) and homotopy perturbation Sumudu transform method (HPSTM) are implemented to give a series solution of fractional convection-diffusion equation which describes the flow of heat. These proposed techniques introduce significance in the field over the existing techniques that make them computationally very attractive for applications. Numerical solutions clearly demonstrate the reliability and efficiency of HATM and HPSTM to solve strongly nonlinear fractional problems. © 2016 Faculty of Engineering, Ain Shams University. Source

An artificial neural network (ANN) has been developed and tested for wired bow-tie antenna design. It transforms the data containing the frequency (fr) and power gainn (G) to the dimension of antenna in x and y direction, dx and dy respectively. © 2015 IEEE. Source
