Modeling of pore pressure propagation and dissipation in compressible porous media
… of the different phenomena associated with the propagation of pore water pressure in high plasticity clays. Specifically, it addresses the pore pressure response in areas subjected to sudden increases in pore water pressure at their top boundary. The main applications of this research would be …

In-situ monitoring of an Omni directional roof vent on a low slope single ply roof to identify most efficient porous underlayment for maximum pressure propagation
… distributional characteristics of negative air pressure throughout the roof assembly, when subjected to suction pressure corresponding to different wind speeds. Various underlayments were tested at the Research & Demonstration Facility at Virginia Polytechnic Institute and State University to …

Hydrology of a large unstable hillslope at Ebnit, Vorarlberg : identifying dominating processes and structures
… surface and subsurface hydrological processes. Pressure propagation induced in hydrological active areas influences laterally the groundwater reactions of the moving mass. A complex three-dimensional subsurface pressure system is the cause for fast groundwater reactions despite low hydraulic …

A wearable blood pressure sensor using oscillometric photoplethysmography and micro accelerometers
Monitoring arterial blood pressure (ABP) with a sensor virtually imperceptible to the wearer, for continuous periods of weeks, months, or years, could prove revolutionary in the diagnosis and treatment of chronic hypertension and heart failure, as well as a monitoring tool for convalescing …

Fluid and Pressure Dynamics in Natural and Engineered Coastal Aquifer Systems
… flow and geological heterogeneity influence pressure response, intrusion geometry, and deformation in stressed coastal systems. Three aquifer domains are examined: homogeneous aquifers, confined aquifers with continuous clay layers, and heterogeneous aquifers containing discontinuous clay …

Quantifying non-Fickian transport in porous and fractured media using fractional-calculus based stochastic models
… to identify non-Darcian flow and non-Fickian pressure propagation. Finally, to address non-Fickian transport for reactive pollutants, I proposed a time fractional derivative model with the reaction term. Findings of this dissertation improve our understanding of the nature of water flow and …

Open abdomen therapy with vacuum-assisted wound closure and mesh-mediated fascial traction
… in an OA with regards to the extent of negative pressure reaching the bowel, the efficacy of the VAWC system in draining fluid from the abdominal cavity and whether paraffin gauzes can be effectively used as pressure isolation when placed between the vacuum source and the bowel. …

Microfluidic investigation of cyclic solvent injection: from reservoir-on-the-chip to large scale
… systems, it was found that solvent type, pressure depletion rate, and reservoir characteristics had a significant influence on the extension of foamy oil flow. Accordingly, solvents containing a higher proportion of CO2 exhibited superior performance, primarily due to their ability to …
