In the present work, the design and microfabrication of a tunneling magnetoresistance (TMR) electrical current sensor is presented. After its physical and electrical characterization, a wattmeter is developed to determine the active power delivered to a load from the AC 50/60 Hz mains line. Experimental results are shown up to 1000 W of power load. A relative uncertainty of less than 1.5% with ...

Dielectric properties of an organic material, which shows conductance switching with associated memory phenomenon, have been studied. The devices have been modeled as a parallel combination of a resistor and a capacitor. During conductance switching, devices resistive and capacitive properties have been found to change. Multilevel conductivity, which is due to different density of high-conducti...

Delay faults are an increasingly important test challenge. Traditional delay fault models are incomplete in that they only model a subset of delay defect behaviors. To solve this problem a combined delay fault (CDF) model has been developed, which models delay faults caused by the combination of spot defects, parametric process variation, and capacitive coupling. The spot defects are modeled as...

This article presents design and fabrication methodology of Ku Band (linearly polarized) reconfigurable patch antenna. Both bulk and surface micromaching techniques are implemented on patch to have better RF performances. Reconfigurability is implemented by integrating shunt capacitive switch with microstrip patch antenna. Effect of feed mechanisms and role of micromachining on antenna paramete...

Force-feedback mechanisms have been designed to simplify and enhance the humanvehicle interface. The increase in secondary controls within vehicle cockpits has created a desire for a simpler, more efficient human-vehicle interface. By consolidating various controls into a single, haptic feedback control device, information can be transmitted to the operator, without requiring the driver’s visua...

This thesis proposes a complete modeling and control design methodology for a multifunctional single-phase bidirectional PWM converter in renewable energy systems. There is a generic current loop for different modes of operation to ease the transition between different modes, including stand-alone inverter mode, grid-tied inverter mode, grid-tied rectifier mode and grid-tied charger/discharger ...

Nicorandil, although structurally a nitrate, differs from classic nitrates in several respects. It preferentially dilates resistive vessels. Its effect on venous return in dogs is not unanimously a decrease but rather an increase. In high doses or concentrations it suppresses myocardial contraction and ventricular automaticity, nearly sparing sinoatrial nodal automaticity and atrioventricular n...

Electrical waveforms measured during propagation at microscopic level are considerably affected by normal variations in cardiac microstructure as well as by the superfusing fluid. On the basis of evidence we present in this article, we argue that the anisotropic waveform variations discussed here are explained primarily by the associated variations in different microstructural components of myo...
