Analysis of wormhole routings in cayley graphs of permutation groups.
(1999)
Over a decade, a new class of switching technology, called wormhole routing, has been investigated in the multicomputer interconnection network field. Several classes of wormhole routing algorithms have been proposed. Most ...
An integrated concurrency control in object-oriented database systems.
(1997)
First, the dissertation discusses three important issues of concurrency control in OODBs. These include conflict among methods, class hierarchy locking, and nested method invocations. The previous works for each issue are ...
Transaction management in mobile multidatabases.
(1999)
This dissertation studies transaction management in the mobile Multidatabase environment. That is, it studies the management of transactions within the context of the mobile and Multidatabase environments. Two new transaction ...
On merging sequencing and scheduling theory with genetic algorithms to solve stochastic job shops.
(1997)
The stochastic job shop problem was solved using two genetic algorithms. The first was a stochastic constrained genetic algorithm to minimize total tardiness and to evaluate chromosomes using probability Gantt charting. ...
Primal-dual techniques for nonlinear programming and applications to artificial neural network training.
(1997)
In this work, new developments in primal-dual techniques for general constrained non-linear programming problems are proposed. We first implement a modified version of the general nonlinear primal-dual algorithm that was ...
Large-eddy simulation of stratocumulus-topped boundary layer with an explicit and a new bulk microphysics scheme.
(1997)
The realism of the model is evaluated by a direct comparison of the model predictions with the aircraft observations of the STBL. The first case study is based on the UKMRF flight 526 measurements collected over the North ...
Scalability analysis of large codes using synthetic perturbations and factorial designs.
(1997)
A class of interaction plots using speedup is introduced in this dissertation that will enable the investigator in comparing the scalability of two parallel systems.
Advanced computational methods in acoustic tomography.
(1997)
An alternative approach is based on the field theory of wave propagation. A finite difference solution of the wave equation for an anisotropic medium is used. The material properties can be reconstructed using a modification ...
Information technology use and employee empowerment: An historical event analysis approach to testing a theoretical model.
(1998)
This dissertation addresses the following research questions: (1) How does increased interaction with computerized information technology affect user empowerment; (2) How can historical data be used to test theoretical ...
Development and Testing of a New Transport Protocol Optimized for Multimedia Internet Transactions.
(1999)
The TCP/IP protocol, which carries over 95% of data across the Internet, was first published in 1974 at a time when packet-switching was a new technology and computer communications were dominated by the virtual-circuit ...
