High-quality data on building energy use and indoor pollution are critical to supporting government efforts reduce carbon emissions improve the population’s health. This study describes development of a city-representative housing stock model used for estimating space-cooling PM2.5 exposure across Hong Kong stock. Archetypes representative dwellings were developed based geographically-reference...

Metal piping in industrial plants is subject to corrosion under insulation, which reduces the wall thickness and limits service life operating conditions. The Pulsed Eddy Current (PEC) technique can be effective inspection of isolated metallic materials. However, changes magnetic permeability make its use difficult ferromagnetic steels. In this work, we used Neodymium magnets magnetize material...

Moisture inside the footwear can considerably affect the thermal insulation. In this study with a thermal foot model there was simulated three sweat rates (3, 5 and 10 g/h). Five types of footwear with various insulation levels (dry insulation from 0.19 to 0.50 m2. K/W) were tested. The footwear insulation reduction was calculated for 1.5 hour period. The reduction in insulation was related to ...

We develop an approach to utilize anisotropic metamaterials to solve one of the fundamental problems of modern plasmonics--parasitic scattering of surface waves into free-space modes, opening the road to truly two-dimensional plasmonic optics. We illustrate the developed formalism on the examples of plasmonic refractor and plasmonic crystal, and discuss limitations of the developed technique an...
