Approximately 40% of the overall energy consumption society is consumed by buildings. Most building usage due to poor envelope performance. In regions with cold winters, corners structures typically have lowest interior surface temperature. corners, condensation, frost, and mold are common. This has a substantial effect on residents’ comfort. this study, heat loss corner envelopes evaluated, su...

It has been shown that none of any energy sources which own high specific energy or high specific power, but not both, can solely fulfil all the demands of hybrid electric vehicle (HEV) in some circumstances. In this paper a simulation model for battery/ultra-capacitor hybrid energy storage system (B/UC HESS) was presented by Matlab/Simulink. Based on the model a low-pass filtering control stra...

Based on identifications from the Véron and Quasars.org catalogs, we determine the optical-to-X-ray spectral indices for a sample of 201 BL Lac type objects (BLLs) and search for trends in the distribution of these indices of the sources detected in highenergy bands. We find that EGRET-detected sources are low-energy peaked and that the positional correlation with the arrival directions of ultr...

Pulsed ALOHA is a form of impulse Ultra-Wideband communication where a bit is carried with each pulse, rather than using a time spreading code. Pulsed ALOHA and Wideband ALOHA are perfect fits to low energy wide-bandwidth communication. They permit energy-efficient higher data rates. Pulsed ALOHA has some unique advantages in collision avoidance and collision tolerance over Wideband ALOHA, when...
