Spiral- And Scroll- Wave Dynamics In Ironically And Anatomically Realistic Mathematical Models For Mammalian Ventricular Tissue
(2017-05-24)Cardiac arrhythmias, such as ventricular tachycardia (VT) and ventricular fibrillation (VF), are among the leading causes of death in the industrialized world. There is growing consensus that these arrhythmias are associated ... -
Study of Phase Transitions in Two Dimensions using Electrical Noise
(2017-11-21)It is well known from Mermin-Wagner theorem that a two dimensional(2D) system with continuous symmetry can have no long-range order at finite temperature. However such systems can undergo a transition from a low temperature ... -
A Study of Slow Modes in Keplerian Discs
(2018-02-25)A rich variety of discs are found orbiting massive bodies in the universe. These could be accretion discs composed of gas around stellar mass compact objects fueling micro-quasar activity; protoplanetary discs, mainly ... -
Study of Thermoelectric Properties of Lead Telluride Based Alloys and Two-Phase Compounds
(2018-01-03)The growing need of energy worldwide has lead to an increasing demand for alternative sources of power generation. Thermoelectric materials are one of the ‘green energy sources’ which convert directly heat into electricity, ... -
Thermoelectric Propeties of Cu Based Chalcogenide Compounds
(2017-12-12)Thermoelectric (TE) materials directly convert heat energy into electrical energy. The conversion efficiency of the TE devices depends on the performance of the materials. The conversion efficiency of available thermoelectric ... -
Threshold Voltage Shift Compensating Circuits in Non-Crystalline Semiconductors for Large Area Sensor Actuator Interface
(2018-02-25)Thin Film Transistors (TFTs) are widely used in large area electronics because they offer the advantage of low cost fabrication and wide substrate choice. TFTs have been conventionally used for switching applications in ...
