Extension of path probability method to approximate inference over time
There has been a tremendous growth in publicly available digital video footage over the past decade. This has necessitated the development of new techniques in computer vision geared towards efficient analysis, storage, ... -
Incremental techniques for code generation problems
Incremental compilation plays an important role in the functioning of integrated programming environments. The earlier phases of compilation like lexical analysis, parsing, semantic analysis, and dataflow analysis have ... -
Compiling for a dataflow runtime on distributed memory parallel architectures
Programming for parallel architectures that do not have a shared address space is tedious due to the need for explicit communication between memories of different compute devices. A heterogeneous system with CPUs and ... -
Optimal linear regular tree pattern matching using pushdown automata
Code generation is a difficult and complex phase of compiler writing. Most problems associated with the code generation phase are NP-complete; therefore, heuristics have been employed to solve them. Instruction selection ... -
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 ... -
Numerical integration of ordinary differential equation on multiprocessing systems
In this thesis, we explore how to solve Ordinary Differential Equations (ODEs) on parallel computers. A comprehensive study of the current state-of-the-art methods for both sequential and parallel integration of ODEs is ... -
Design of parallel algorithms for a multiple bus multiprocessor system
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 discusses the design of parallel algorithms for the compilation process. The model of computation is an SIMD (Single Instruction, Multiple Data) computer with shared memory, where no read or write conflicts are ... -
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 ... -
Performance evaluation of computer systems using discrete event simulation
Chapter II This chapter discusses the currently available modeling techniques and the studies conducted using these techniques. Chapter III It presents a performance evaluation of Batch and Time-sharing systems. The ... -
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 ... -
Object cache : a dynamically configurable and energy efficient cache architecture for embedded systems
Object-oriented programming languages provide a rich set of features that provide significant software engineering benefits. The increased productivity provided by these features comes at a justifiable cost of complexity ... -
iSAN : An intelligent storage area network
A storage area network (SAN) is a high-speed special-purpose network that interconnects data storage devices and storage-consumers. Present day SANs, based on Fibre Channel or iSCSI, share a common deficiency: Neither of ... -
Fault tolerant locking for shared disk filesystems
Shared disk files ystems are crucial for providing direct, shared and high performance file system access on top of raw block based Storage Area Networks. One of the key components of a shared disk file system is a ... -
