Studies in Probabilistic Model-Building Evolutionary Algorithms
Evolutionary algorithms (EAs) are a family of metaheuristics inspired by Darwin's theory of evolution through natural selection. They maintain and evolve a population of candidate solutions through stochastic variation and ... -
Modeling the Switching Dynamics of Advanced Power Semiconductor Devices: From Silicon Superjunction to Wide Bandgap Technologies
The advancement of power semiconductor devices has significantly transformed modern power conversion systems, enabling notable enhancements in energy efficiency, system miniaturization, and overall performance. Among the ... -
Adaptive algorithms for admission control of elastic sessions in the internet
Elastic traffic dominates Internet usage and is characterized by its tolerance to loose performance guarantees. However, when network performance drops below a minimum acceptable threshold - especially under high load - ... -
Performance analysis and optimization of scheduling in high speed input queuing cell switches
This thesis investigates techniques to improve throughput and reduce delay in input-queued cell switches, particularly focusing on the Head-of-the-Line (HOL) blocking problem. While pure input queuing suffers from limited ... -
Some new architectures for fuzzy logic processing
Fuzzy Logic has gained immense popularity in the last decade for use in several scientific and industrial applications. In this context, a substantial role is played by the computational structures used to perform fuzzy ... -
Alternative interleaving schemes for interleaved orthogonal frequency division multiplexing
Interleaved OFDM was proposed as an effective solution for improving code rate over slowly varying channels, without affecting the Peak-Average Power Ratio. The system was proposed with a particular interleaving scheme. In ... -
Computer recognition of hand printed characters: an automated approach to the design of recognizers
Computer Recognition of Handprinted Characters is a well-established field of research, active for over three decades. Despite extensive work and numerous publications, the ultimate goal of developing a recognizer with ... -

Matrix operations play a crucial role in scientific computations. This thesis presents the design and analysis of four parallel matrix computation algorithms specifically suited for a broadcast bus-based Multiple Bus ... -
Dependency-lattices, acyclic hypergraphs and relational database scheme design
Compared to other models of data, the relational model offers several advantages: Clear separation between logical organization and physical storage of data Ease of understanding the logical structure Use of high-level ... -
Multiprocessing architectures for parallel hidden surface removal algorithms
Interactive computer graphics systems have become powerful tools for man-machine interaction, with wide-ranging applications. One particularly exciting and important area is the synthetic generation of realistic images of ... -
Parallel algorithms for compilation.
This thesis explores the design of parallel algorithms for the compilation process, using a SIMD (Single Instruction, Multiple Data) shared memory architecture that avoids read/write conflicts. Several phases of compilation ... -
New techniques for the analysis of two and three dimensional objects
The results of an investigation carried out on certain pattern recognition aspects of a class of two-dimensional line drawings and three-dimensional objects are reported in this thesis. The motivation for the proposed ... -
Design for complete testability and fault diagnosis of programmable logic arrays
The primary objective of this thesis is the formulation of a systematic procedure for the conversion of a Programmable Logic Array (PLA) having untestable faults into a corresponding completely testable PLA. In a completely ... -
Transputer-based parallel implementation of neural nets for a class of pattern recognition problems
Neural networks are systems that are made up of a number of computing elements connected to each other making use of some of the organizational principles that are thought to be used in the human brain. For a large array ... -
Deterministic dynamic race detection across program versions
Dynamic race detectors operate by analyzing execution traces of programs to detect races in multithreaded programs. As the thread interleavings influence these traces, the sets of races detected across multiple runs of ...
