Solution of conservation laws via convergence space completion
It is well known that a classical solution of the initial value problem for a scalar conservation law may fail to exist on the whole domain of definition of the problem. For this reason, suitable generalized solutions of such problems, known as weak solutions, have been considered and studied …

Existence and uniqueness of solutions of boundary value problems by matching solutions.
… dissertation, we investigate the existence and uniqueness of boundary value problems for the third and nth order differential equations by matching solutions. Essentially, we consider the interval [a, c] of a BVP as the union of the two intervals [a, b] and [b, c], analyze the solutions of the …

La méthode de tir pour des problèmes de programmation linéaire bicritères
… de ces problèmes, il existe un ensemble de solutions optimales et non pas une unique solution au problème, ce qui pose la question de la manière de visualiser et d'analyser cet ensemble de solutions. Nous avons utilisé les bases de l'optimisation multicritère et la méthode de la somme …

The Case for Casein Fiber: Local Design Solutions for Sustainability in Manufacturing
Abstract In order to propose solutions to known problems, designers must consider the system in which their creations exist and design with the entire system in mind. Through literature research and expert interviews on the subject of textile and apparel manufacturing, this paper examines the …

A Hybrid Connectionist-Instance Model of Recognition Memory
… which is often called catastrophic interference. Solutions to the catastrophic interference problem in turn sacrifice the properties that make these models attractive. This dissertation proposes an alternative connectionist model of recognition memory, which contains a solution to the catastrophic …

An Improved Approach to Fault Tolerant Redundant Fiber Optic Ring Design for Polled Data Networks
… ring for polled network applications. FDDI and a unique solution (the tone method) designed specifically for this application are compared. In polled networks one of the most critical parameters is the time required to interrogate all of the nodes in the network. This parameter, called the poll …

Development, Evaluation, and Analysis of Complex Eye Movement Biometrics
Eye movements present a novel and unique solution to the challenges faced by modern biometrics. Consisting of both physical and neurological components, and due to the minute scale, the accurate replication of eye movements outside of a living subject is practically infeasible (if not impossible), …

Almost well-posedness of the full water wave equation on the finite stripe domain
… equations is given, the long-time existence of a unique solution for the Euler equations is still an open problem, even if the initial condition is small (or initial flow is almost motionless). The dissertation tries to make some progress for proving the long-time existence and show that the time …
