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 …

General queueing network models for computer system performance analysis. A maximum entropy method of analysis and aggregation of general queueing network models with application to computer systems.
In this study the maximum entropy formalism [JAYN 57] is suggested as an alternative theory for general queueing systems of computer performance analysis. The motivation is to overcome some of the problems arising in this field and to extend the scope of the results derived in the context of …

A dynamic, entropy minimizing, equilibrium-oriented approach to transportation planning
… future spatial organization because as an entropy maximizing approach, it provides the only unbiased situation which can be assumed. While the maximum entropy solution to a problem is the most natural solution, it is not the most desirable solution. In summary, what we have today is a case …

A Numerical Method for solving the Periodic Burgers' Equation through a Stochastic Differential Equation
… these equations can develop discontinuous solutions (or solutions with large gradients) from smooth initial data. Aside from numerical stability issues, standard numerical methods can also give rise to spurious oscillations near these discontinuities. In this study, we consider an …

Invariant-region-preserving discontinuous Galerkin methods for systems of hyperbolic conservation laws
… designing an IRP limiter to modify the numerical solution and identifying sufficient conditions for IRP DG schemes by extending Zhang and Shu's work on positivity-preserving schemes for conservation laws [X. Zhang and C.-W. Shu., Journal of Computational Physics, 2010]. The one-dimensional model …

Essays on production chains and disruptions: new input-output perspectives on time, scale and space
… at these scales, I devise a maximum cross-entropy solution that allows the inclusion of specific temporal information for the region. As an example, I highlight the seasonal economic characteristics of the State of Illinois and two of its counties (Cook and Iroquois). Chapter 3 introduces a …
