Materials with a strong spin Hall effect and Rashba-Edelstein effect have the potential to improve the efficiency of solid-state magnetic memory technologies and other magnetic logic devices. Heavy metals have been identified as having these properties, including the beta crystal phase of tungsten. In this work, we determine the strength...
Memory hierarchy design is becoming more important as the speed gap be- tween processor and memory continues to grow. Investigations of memory perfor- mance have typically been conducted using trace-driven emulation, which could take tremendous resources (e.g. long emulation time, large storage requirements for traces, and high overall cost). Recent...
An important task of a Variable Speed Generation (VSG)
system is the capability to maintain and control the terminal
voltage at some desired value as determined by the
reactive power dispatch strategy.The main objective is to
design a sub-optimal fixed-parameter controller in the
sense that constraints with respect to practical...
With the advent of LSI, iterative forms of realization
of digital systems are becoming increasingly popular with
system designers. Many problems occurring in digital computer
design render themselves suitable for iterative
realization. These include adders, arithmetic logic units,
coding and decoding circuits and so on. Fault-free functioning
of such systems...
A Brushless, Doubly Fed Machine (BDFM) attempts to combine the advantages
of conventional induction and synchronous types of electrical machines by its unique
architecture. The validation of BDFM designs in an actual test environment requires the
estimation of the BDFM model parameters from actual experimentation. Accurate values
for the parameters...
A systematic optimization of the Cohen class time-frequency
transformation for detecting the parameters change is developed.
The local moments approach to change detection is proposed and a
general formula for the local moments is derived. The optimal
kernel functions of the time-frequency transformation are determined
based on the combined criteria...
In an attempt to provide a practical means to measure the information
processing capacity of a real-time digital processing system a
theoretical framework, the Real-Time Schemata, whose basis is a
schematic description and a measure of "useful information," is presented.
The description applies to processes that would typically be
implemented...
Mathematical morphology, developed in the early 1960's for
single-component signals, has been applied to a number of image
processing applications. This investigation examines the systematic
extension of mathematical morphology to multi-variate signals.
Two approaches are considered. The first approach, the
extension of the theory of single-component morphological filters to
multi-variate...
Morphological filters have shown good performance in various image processing applications. Furthermore, their algorithms are easy to implement in special architectures, with the exception that linear filtering cannot be implemented in many of these cases. In this study, a new architecture and corresponding algorithm, capable of realizing linear shiftinvariant filters,...
