Title of Dissertation: DEVELOPMENT OF MAGNETORHEOLOGICAL FLUID ELASTOMERIC DAMPERS FOR HELICOPTER STABILITY AUGMENTATION Wei Hu, Doctor of Philosophy, 2005 Dissertation directed by: Professor Norman M. Wereley Department of Aerospace Engineering Conventional lag dampers use passive materials, such as elastomers, to dissipate energy and provide stiffness, but their damping and stiffness levels d...

In this experimental work, the microbiological, physicochemical, organoleptic, and rheological properties of yoghurts produced by ultrafiltered goat’s milk using two volume-reduction ratios three probiotic starters were studied. It was established that dry matter, fats, proteins, count lactic acid bacteria, titratable acidity, dynamic viscosity increased pH decreased with rise ratio during ultr...

Previously conducted studies have established that the soil–rock mixture in Chongqing area has characteristics of loose structure, poor stability, strong permeability, and so on. When building a tunnel stratum, it is necessary to reinforce surface rock mass surrounding by grouting improve safety excavation. To study diffusion mechanism cement slurry (Bingham fluid) mixtures, based on Bingham fl...

Diffusion MRI (dMRI) measurements are used for inferring the microstructural properties of white matter and to reconstruct fiber pathways. Very often voxels contain complex fiber configurations comprising multiple bundles, rendering the simple diffusion tensor model unsuitable. Multi-compartment models deliver a convenient parameterization of the underlying complex fiber architecture, but pose ...

In this work, we develop a method of straight lines for solving a Bingham problem that models the flow of waxy crude oils. The model describes the flow of mineral oils with a high content of paraffin at temperatures below the cloud point (i.e. the crystallization temperature of paraffin) and more specifically below the pour point at which the crystals aggregate themselves and the oil takes a je...

Datasets obtained by viscometry of Fuji 1707 basalt at a pressure of one atmosphere (Ishibashi, 2009) were analyzed by using the Bingham fluid model, and both the yield stress (τy) and Bingham viscosity (ηB) were determined. The relation between ηB and the crystallinity (Φ) was compared with the Krieger-Dougherty equation, and both the maximum packing fraction of crystals (Φm) and intrinsic vis...
