Recent improvements in HVAC control networking technologies together with an improved understanding of the nature of cooling loads in buildings offer enormous potential improvements in the cost effectiveness of district cooling plants. By carefully coordinating the district cooling plant design with a digital controls network to the loads served, the following economic advantages over tradition...

The chemical reduction of the K2NiF4-type oxides, Ln2Sr2CrNiO8 d (Ln 1⁄4 La, Nd) and Nd2.25Sr1.75CrNiO8 d, has been investigated in situ under a dynamic hydrogen atmosphere at high temperature using neutron powder diffraction. The high count-rate and high resolution of the D20 diffractometer at ILL, Grenoble allowed real-time data collection and structure refinement by fullpattern Rietveld anal...
-The present investigation is based on the effect of thermal residual stresses on the both thermal expansion and damping behavior of Al/Al2O3 Metal Matrix Composites (MMCs) processed by compo casting. Thermal expansion and damping properties have been studied experimentally as a function of temperature over a temperature range from room temperature to 400°C both in the heating and cooling cycle...
