Knowledge-based mining of multi-database for associations
Knowledge Discovery in Databases (KDD) uses knowledge engineering tools and database technology to extract hidden patterns from databases. Data mining is a step in the KDD process that finds useful patterns in the data. ... -
Stokes polarimetry and the measurement of vector magnetic fields in solar active regions.
The aim of this thesis has been measurement of Stokes profiles and vector magnetic fields in sunspots using the Kodaikanal Tower/Tunnel Telescope and spectrograph. Although this coelostat telescope had been constructed ... -
Design and perfomance evaluation of bus access schemes for salan-an experimental local area network
Local Area Networks (LANs) spanning a limited geographic area have emerged of late as a field of wide applicability. One of the prime factors governing the design of a LAN is the Medium Access Control (MAC) scheme which ... -
Combinatorial algorithms for determinant based problems
The thesis started with the early history and development of the theory of determinants. All the important results up to the 1880s were presented through a computing perspective. Pfaffians are closely related to determinants; ... -
Application of finite graph models of context fue languages.
A finite graph model for a context?free language is proposed. The model is called an extended transition system; its nodes encode [pushdown automata state, top stack symbol] pairs and its arcs encode pushdown automaton ... -
Concurrency control algorithms for database systems exploiting the semantics of read-only transactions.
This thesis proposes new locking-based concurrency control algorithms for both centralized and distributed databases. The concurrency control algorithms proposed exploit the semantics of read-only transactions to improve ... -
Pattern recognition via Fuzzy set methods
The main objective of this thesis is the development of a methodology based on fuzzy set theory for several practical pattern recognition problems. Pattern recognition (PR) encompasses a range of problems from feature ... -
Modelling program dynamics : A study on locality of reference
Locality of reference is a phenomenon exhibited by programs and computer systems in general, and refers to the tendency to localize operations to a small subset of the available resources. In the past, this phenomenon has ... -
Algorithms and characterizations for subclasses of planar perfect graphs
In this thesis, we consider two major subclasses of planar perfect graphs. We exploit certain decomposability and ordering properties to develop new characterizations and efficient algorithms. We study the Hamiltonian cycle ... -
Design of electronic exchanges through decomposition
Decomposition-Based Approaches for Clearing Electronic Exchanges Electronic marketplaces have emerged in recent times as the backbone of important e-commerce and e-business applications to create efficient markets for ... -
AMI-The language and its implementation
Automatic translation of sequential programs to parallel programs which can reasonably exploit distributed memory machines is very difficult and not well-understood. Programming with communication-based statements is very ... -
Nondeterminism and communication in functional progamming systems: a study in formal program development
In this thesis, a Relational Database Management System that supports a query/data manipulation language along with facilities like database creation is presented. A compiler model chosen for translating the input statements ... -
Monitoring program dynamics : Evaluation of software profiler effectiveness
Program monitoring tools are often used to verify program correctness, study program performance, and identify performance bottlenecks. Program profilers are a class of program monitoring tools which aid in tuning the ... -
Interaction paradigms for distributed object-oriented programming
Current trends in large-scale distributed programming on a network of workstations are experiencing a paradigm shift into object-orientation. This is primarily driven by the need for modular, compact, portable and reusable ... -
PEG: a programming environment generator
Integrated piogramming enviionments play an im portant role in making the software development process easier and more efficient. Since there exist a number of programming languages, it is necessary to provide programmers ... -
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 ... -
Pattern classification using conjuctive conceptual clustering procedures
This thesis deals with the salient features of the conjunctive conceptual algorithm CLUSTER/2 and describes new algorithms based on conjunctive concepts to overcome some of the problems associated with CLUSTER/2. From a ... -
Secure ECom framework for small-communities
Universal reach of the web has made it possible for merchants to reach their customers, and vice versa, through what has now come to be referred as Electronic Commerce, or ecom in short. Despite admitting the new opportunities ... -
Learning subspace methods using weighted and multi-subspace representations
The learning subspace methods (LSMs) of classification are decision-theoretic pattern recognition methods where the primary model for a class is a linear subspace of the Euclidean pattern space. Classification is based on ... -
Techniques in The Markov Chain Monte Carlo Method
Consider the problem of sampling from a set of combinatorial objects according to a certain given distribution. The Markov chain Monte Carlo (MCMC) method is a possible solution for this problem. The method consists of ...
