Relaxation labeling algorithms introduced by Rosenfeld et al., have been widely used in image and sequence matching applications. The underlying mechanism of labeling via relaxation is a deterministic dynamical system whose initial status converges to one of the attractors. This is also a process of the input image segments being assigned the predetermined labels in a parallel and unsupervised ...

For this thesis, several tools for dynamic model development were developed and analyzed. Dynamic models can be used to simulate and optimize the behavior of a great number of natural and engineered systems, from the movement of celestial bodies to projectile motion to biological and chemical reaction networks. This thesis focuses on applications in chemical kinetic systems. Ordinary differenti...

The aim of this study was to investigate the usefulness of magnetic resonance (MR) imaging in the evaluation of renal function, with particular attention to the effects of water load. Ten healthy volunteers underwent dynamic MR imaging after an injection of gadolinium diethylene-triaminepenta-acetic acid (Gd-DTPA) as a contrast agent to evaluate renal function by the following four methods: the...

This thesis is organized into two parts which focus on the studies of the dynamic structure factor and static inter-particle structure factor respectively. In the first part, we have measured and analyzed the dynamic structure factors of aligned 40 wt% calfthymus Na-DNA molecules with the inelastic X-ray scattering (IXS). In the second part, we have developed a new efficient method to calculate...

The dynamic dilution theory of stress relaxation, quantitative for star polymer melts, cannot be directly applied to star-linear blends. The linear chains on their reptation time scale τd release constraints on the star arms, resulting in constraint-release Rouse motion for the star arms not described by dynamic dilution. We present a microscopic theory without adjustable parameters for stress ...

In this paper, a step fixed charge transportation problem is developed where the products are sent from the sources to the destinations in existence of both unit and step fixed-charges. The proposed model determines the amount of products in the existing routes with the aim of minimizing the total cost (sum of unit and step fixed-charges) to satisfy the demand of each customer. As the problem i...
