Evaluation of thermographic techniques for the detection of subsurface delaminations in concrete bridge substructures
… is made to assure uniform emissivity. 3) Hot air heating is a viable technical alternative which does not require surface preparation prior to the application of heat. However, this method does require some type of enclosure to produce a hot air pocket. 4) Artificial heating methods based on …

Advanced Manufacturing and Dielectric Material Characterization Techniques for High-Temperature mm-Wave Antennas
… CPW structure. Furthermore, by creating air pocket slots in the CPW structure, the loss tangent of the material can be determined by extracting the attenuation constant at various depths. To verify this methodology, a mathematical model is developed for CPW structures with air pocket …

The behaviour of Siphon Spillways, with particular reference to air entrainment and model scale effects
This work is a broad study of the mechanisms of air entrainment and air regulation in self-priming, air-controlled siphon spillways. The early chapters of the work provide the reader with the history and general design principles of siphon spillways as well as a comprehensive review of the research …

An Exploration of Transient Protection of Pressurized Pipelines using Air Valves
… having undulating profiles and containing air vacuum valves (AVVs) is systematically explored to characterize the critical high points where placing AVVs has the maximum influence on the resulting transient pressures. For this purpose, this work seeks to understand the principal function of …
