Dispersion, controlled dispersion, and three applications
… index varies with frequency.) Ordinarily, strong dispersion is accompanied either by strong absorption or strong gain. However, over the past 15 years several groups have demonstrated that it is possible to have media that are both strongly dispersive and roughly transparent for some finite …

Modeling Traffic Dispersion
The dissertation studies traffic dispersion modeling in four parts. In the first part, the dissertation focuses on the Robertson platoon dispersion model which is the most widely used platoon dispersion model. The dissertation demonstrates the importance of the Yu and Van Aerde calibration …

Carbachol-Induced Pigment Granule Dispersion
… and acetylcholine analog, has on pigment granule dispersion in a dose-dependent manner, and the maximum effects of carbachol were observed at concentrations as low as 10 nM. Atropine was highly effective in blocking carbachol-induced dispersion. The role of specific muscarinic receptor subtypes …

Wage Dispersion Between College Majors
"The United States has benefitted from an educated workforce that has been integral to the growth in productivity and innovation in various industries. The education system, which was built to be largely public and egalitarian, allowed individuals of every background to reach their productive …

Fluctuating concentrations in atmospheric dispersion
… measurements from a series of atmospheric dispersion experiments conducted under both unstable and stable meteorological conditions. The experiments were undertaken at two different sites, over both flat and gently rolling terrain. Two types of surface-level point aerosol sources were used. …

Phonon Dispersion Relations in Chrystals
… a single crystal enables us to deduce the phonon dispersion relation, that is the frequency of the normal modes as a function of their wave vectors. These experiments provide a far more direct test of theories of crystal dynamics than do specific heat measurements. The possibility of experimental …

Longitudinal dispersion in vegetated flow
… flow structure, and thus both advection and dispersion. Accurate prediction of the fate and transport of nutrients, microbes, dissolved oxygen and other scalars depends on our ability to quantify vegetative impacts. In this thesis, the focus is on longitudinal dispersion, which traditionally …

Reaction-Diffusion Models of Cancer Dispersion
… evolution of one-dimensional models of cancer dispersion are studied. The models discussed pertain primarily to the transition of a tumor from an initial neoplasm to the dormant avascular state, i.e. just prior to the vascular state, whenever that may occur. Initiating the study is the …

Dispersion of particles on liquid surfaces
… a liquid surface, they immediately disperse. The dispersion can occur so quickly that it appears explosive, especially for small particles on the surface of mobile liquids like water. This explosive dispersion is the consequence of capillary force pulling particles into the interface causing them …

Solute dispersion in selected tropical soils
The dispersion of chloride, nitrate, potassium, calcium, and phosphate was investigated in three tropical soils represented by three Hawaiian soils through a specially designed flow apparatus. Observed differences in the dispersion of these solutes for the range of velocities tested were attributed …

Shear Dispersion in Double-Porosity Systems
In this study, shear dispersion in double-porosity systems has been investigated. The major focus of this study is determination of dispersion coefficients through development of mathematical models for solute transport in a variety of coupled double-porosity systems by imposing an accurate …

Experimental transmission of dispersion managed solitons
… 1150nm over standard fibre. This is done using a dispersion compensating fibre module in each amplifier span to compensate for the high dispersion. The basic principles of soliton propagation in optical fibre are discussed within this thesis, followed by an introduction to advantages of dispersion …
