In-line Sagnac interferometer current sensor
(1995)
We demonstrate for the first time a near shot noise limited
Design issues in a new implementation approach to digital fault simulators for protective relay studies
(1994)
After almost a century of continuous growth, modern power systems are facing contradicting demands of increasing the existing network utilization while improving the overall service reliability. This puts special emphasis ...
Application of finite difference time domain method in RF problems associated with magnetic resonance imaging
(1995)
Magnetic resonance imaging (NM) has been widely applied in medical diagnostics and other fields. It operates at field strengths ranging from a small fraction of a Tesla to as much as four Tesla, with some investigators ...
Design and analysis of a multiplexing data acquisition system for use in magnetic resonance imaging
(1993)
One of the recent innovations in magnetic resonance imaging (MRI) has been the array coil. It has been shown that using array coils and a fixed set of parameters, one can either decrease imaging time, increase image ...
Joint maximum-likelihood sequence and channel estimation for intersymbol interference channels
(1995)
We propose two joint maximum-likelihood estimation approaches. For joint time and data estimation we derive the joint likelihood function for jointly estimating data sequences and timing error for minimum shift keying ...
Defect-assisted tunneling in the Resonant Tunneling Diode
(1993)
The major goal of this research is to understand the current transport mechanisms of the RTD(Resonant Tunneling Diode). A significant discrepancy exists between the predicted and measured values of the RTD current in the ...
Improving microwave circuit testing and producibility with statistical techniques
(1995)
Significant improvements to microwave circuits can be made through the use of statistical methods. This dissertation addresses three aspects of the microwave circuit design process: Modeling, Design Methodology, and Circuit ...
Two dimensional numerical model for the lateral PNP transistor
(1978)
A two dimensional numerical model for the lateral pnp transistor is presented. Heavy doping effects are taken into account by employing doping dependent intrinsic concentration. Terminal characteristics of the injector of ...
Volumetric effects in the depolarization of electromagnetic waves scattered from rough surfaces
(1977)
Theoretical investigations of electromagnetic scatter from rough interfaces have been of interest for many years. Of particular interest is the depolarization of electromagnetic waves scattered from rough surfaces. Early ...
The mutual impedance between coupled electrically thick folded dipoles
(1969)
In this paper an analytical expression for the mutual impedance between two identical, electrically thick coupled folded dipoles in nonstaggered parallel orientation has been developed. A boundary value problem was solved ...
