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 ...
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 ...
Graph models and system diagnosis.
(1997)
The connectivity of a system is an important measure of fault tolerance. Typical interconnection networks are sparse and symmetrical. The classical diagnosis theories, such as t-diagnosability, are not appropriate for these ...
Computational aspects of the adjoint method.
(1997)
Modern numerical weather prediction often employs an adjoint of the forecast model to optimally initialize the model with observations of the state of the atmosphere and thus to improve the accuracy of the forecast. This ...
