This paper investigates the concern that green buildings may promote energy efficiency and other as- pects of sustainability, but not necessarily the health and well-being of occupants through better indoor air quality (IAQ)。 We ask ten...
Abstract The paper presents an idea of an open-loop control of a pneumatic positioning system consisting of a pneumatic cylinder, inexpensive measurement system and four on-off switching valves. A strategy of four pulses on- off control tra...
Asphalt plug joints (APJs) have been used worldwide because of its low cost, ease of installation and repair, low instance of snowplow damage, low traffic noise and ride comfort。 The service life of APJs is relatively short。 Extending...
ABSTRACT Recent improvements to the capabilities of a hybrid Navier-Stokes potential flow methodology for modeling horizontal axis wind turbine (HAWT) configurations are presented. The study focuses on three issues: the effects of turbulenc...
Wind Power Generation Technology Wind is very important and reserves of energy, it is safe, clean, and can provide abundant energy, stability of the stream. Now, use wind power has become the main form of wind, the worlds attention, and the...
Summary Bioinformaticians are tackling increasingly computation-intensive tasks. In the meantime, workstations are shifting towards multicore architectures and even massively multicore may be the norm soon. Bag-of-Tasks (BoT) applications a...
