An experimental set up based on a diffusion bridge is developed to accurately determine the in-plane and through-plane permeability, Knudsen diffusivity and effective molecular diffusivity of gas diffusion layers used in PEFC. The parameters are estimated under various compression levels in...

In this thesis, measurement and analysis of colloidal forces between an atomic force microscope (AFM) probe and a topographically patterned substrate are reported. The energy between the patterned substrate and a smooth flat plate was characterized mathematically using Surface Element Integration...

The Dual Failure Restorability (DFR) problems involve the design of network topology to be restorable in the event of single and dual failures scenarios. We developed new integer linear programming (ILP) models to optimally design mesh topology networks with various survivability schemes; span...

This study experimentally evaluated wheat straw slurry pipelines. Tests were conducted to determine the particle properties of the biomass mixed in water over time. The saturated particle density of 1,060kg/m3 was reached after 24 hours, while the saturated moisture contents of 78.5% and 79.5%...
