Optimization of Piezoelectric-Triboelectric Hybrid Generator Design new

M. Padmanabhan1, G. Barbosa1
1Rhode Island College, Providence, RI, USA

Devices which scavenge energy from ambient mechanical sources such as human body movement and ocean waves are undergoing rapid research and development. Both triboelectric and piezoelectric effects have been employed in the design of such devices. In this work, we use the MEMS Module in ... Read More

Solving PDEs with Spatial & Time Varying Coefficients: Dirac Wave Function Passes Through EM Wave new

A. J. Kalinowski1

The Dirac equation is employed in particle physics and historically gave the first combined unification of quantum mechanics and relativity theory by introducing a four component wave function Ψn n=1…4. This wave function describes the behavior of fermion type particles. The effect of a ... Read More

Stress Concentration Analysis in A Heterogeneous Dough Gas Cell Wall at The Microscale: Effect of Gluten/Starch Interaction and Rheological Moduli Ratio

K. DEDEY[1], D. Grenier[1], T. LUCAS[1]
[1]Irstea Univ Bretagne Loire, France, France

Bread dough is often described as a dispersion of gas cells in a continuous gluten/starch matrix [1]. The final bread crumb structure is strongly related to gas cell walls (GCWs) rupture during baking. At the end of the proofing and during baking, part of the thinnest GCWs between ... Read More

Analysis of Powertrain Mounting System

S. Fulkar[1], C. Deshmukh[1], A. Prasad[1]
[1]Mahindra and Mahindra Ltd., India

Powertrain mounting systems are subjected to varying degrees of continuous dynamic loads resulting into unbalance of forces at their mount locations. These forces contribute significantly towards noise, vibration and harshness signatures in the vehicle cabin and has strong negative ... Read More

Analysis of the Transient Performance of an Annular Linear Induction Pump using COMSOL®

P. Sharma[1]
[1]Indira Gandhi Centre for Atomic Research, India

Annular Linear Induction Pump (ALIP) is used for pumping liquid metal in fast reactors and in experimental test facilities. In order to understand the transient behaviour of this pump, a 2-dimensional axisymmetric model in time domain is developed. The transient performance prediction ... Read More
