During an earthquake, structures are subjected to both horizontal and vertical shaking. Most structures are rather insensitive to variations in the vertical acceleration history and primary considerations are given to the impact of the horizontal shaking on the behavior of structures. In the laboratory, however, most component tests are carried out under uni-directional horizontal loading to si...

today, corrosion in reinforcements is an important issue in many structures, especially those made in off-shore, resulting of reduction of the structural capacity under gravitational and lateral loads. using frp polymer can reduce this effect to some extents. a numerical and experimental investigation has been conducted on three different concrete beams to find out the effect of replacing steel...

This paper explores an efficient Medium Access Control protocol for carrying data traffic via satellite. The Combined Free/Demand Assignment Multiple Access (CFDAMA) protocol combines free assignment of data slots with demand assignment, providing a minimum delay of one round trip time at low loads and the statistical multiplexing gains of demand assignment at high loads. The delay/utilisation ...

This paper considers the optimal multiuser detection problem for the vector Gaussian multiple access channel with multiple inputs and multiple outputs (MIMO). A practical bit-loading and multiuser decision feedback scheme based on generalized decision feedback equalization (GDFE) is proposed. This GDFE-based detection scheme, when used with an optimized transmitter, achieves the extreme points ...

The effects of loading rate on the reinforced concrete beams are experimentally studied in the present paper. Firstly, the effects of strain rate on the different grades of concrete are investigated using the electro-hydraulic servo-controlled testing system at the strain rate that might be experienced during earthquakes. Based on the test results, the dynamic increasing factors (DIF) of concre...

BACKGROUND Intra-Body Communication (IBC), which utilizes the human body as the transmission medium to transmit signal, is a potential communication technique for the physiological data transfer among the sensors of remote healthcare monitoring system, in which the doctors are permitted to remotely access the healthcare data without interrupt to the patients' daily activities. METHODS This wo...

BACKGROUND The purpose of this study was to examine the inter- and intra-rater reliability of an electronic inspiratory loading device for the assessment of pulmonary functions: maximum inspiratory pressure, peak inspiratory flow, and vital capacity. MATERIAL/METHODS Subjects were 50 patient volunteers in a rehabilitation hospital who had experienced their first episode of unilateral stroke w...

The performance of a hybrid bubble column/biofilter (HBCB) bioreactor for the removal of dichloromethane (DCM) from waste gas streams was studied in continuous mode for several months. The HBCB bioreactor consisted of two compartments: bubble column bioreactor removing DCM from liquid phase and biofilter removing DCM from gas phase. Effect of inlet DCM concentration on the elimination capacity ...
