Conventional metal curtain walls have used aluminum frames to support the fireproof boards of spandrels. Since melts at about 660°C, board may fall off in event a fire, causing fire spread upper floors. Therefore, we developed wall supported by frame, and confirmed its performance (prevention falling off) for 2 hours experiments. We also composite insulated steel beams columns using these board...
The aim of this study is to investigate the effects of outside board on rm value in Tehran Stock Exchange (TSE) from the perspective of information transaction costs. To do so, a sample of 96 firms listed in TSE is selected to be studied during the period of 2003-2012. Tobin q ratio is used to measure rm's value and bid-ask spread for information transaction costs. In addition to these variable...
Board-level solder joint reliability is very critical for handheld electronic products during drop impact. In this study, board-level drop test and finite element method (FEM) are adopted to investigate failure modes and failure mechanisms of lead-free solder joint under drop impact. In order to make all ball grid array (BGA) packages on the same test board subject to the uniform stress and str...
A statistical method for the on-board detection and control of oscillatory phenomena in pilot-aircraft systems is presented. Recursive identification is used to obtain a linear model of the system at every time instant. The estimated system parameters are monitored, and the system stability margins are continuously assessed. Oscillations due to stability loss are detected early, using a composi...
A kind of hot spots detection alarm device and method is proposed in the paper about infrared thermal imaging, including the hardware design, algorithm, software realization. The hardware mainly includes the infrared thermal imaging camera and intelligent analysis board; the algorithm uses connected component detection method based on run length to extract target rectangle coordinates. This des...
Competing interests Andrew Seely is Founder and Chief Science Officer of Therapeutic Monitoring Systems (TMS); TMS aims to commercialize patent-protected applications of multiorgan variability monitoring to provide variability-directed clinical decision support at the bedside to improve care for patients at risk for or with existing critical illness. Andrew Seely holds a patent jointly with co-...
