Recorded ground motions in near fault region have completely distinct nature from others that recorded in far field of the fault. Near source outcomes cause much of the seismic energy to appear in a single large and long period pulse at the beginning of the velocity record. Assaluyeh complex is located near the reverse Assaluyeh fault that is a segment of Mountain Front Fault. This complex cont...

ultra-short pulse is a promising technology for achieving ultra-high data rate transmission which is required to follow the increased demand of data transport over an optical communication system. therefore, the propagation of such type of pulses and the effects that it may suffer during its transmission through an optical waveguide has received a great deal of attention in the recent years. we...

OBJECTIVE The effects of acute hemodialysis session on pulse wave velocity are conflicting. The aim of the current study was to assess the acute effects of ultrafiltration on the aortic mechanical properties using carotid-femoral (aortic) pulse wave velocity and pulse propagation time. METHODS A total of 26 (12 women, 14 men) consecutive patients on maintenance hemodialysis (mean dialysis dur...

The cellular effects of gastric electrical stimulation (GES), which has recently been introduced as a potential therapy for the treatment of gastroparesis and obesity, were investigated in rat antrum smooth muscle cells (SMCs). Effects on cell membrane potentials of single electrical current pulses (pulse width from 0.1 ms to 200 ms) and 2-s pulse train stimuli with different pulse widths (0.1-...

We present the effect of dual-pulse temporal shaping on ultraviolet nanosecond laser damage characteristics a fused silica exit surface in high fluence regime. The pre- and post-pulse have opposite effects behavior at pulse delay 20 ns. pre-pulse irradiation significantly increases main-pulse threshold, making it much higher than that single-pulse while has little threshold. For near-threshold ...

Optical pulsing of a laser beam provides a convenient manner for transmitting digital information, and such procedures have led to well-accepted classes of pulse amplitude and pulse position modulation formats. However the excessive pulse dispersion and background light bursts that characterize several optical channels severly limit performance and achievable data rates. One procedure for comba...

introduction : the  rapid development  of wireless telecommunication technologies  over the past decades, has led to significant changes in the exposure of the general public to electromagnetic fi elds. nowadays, people are continuously exposed to different sources of electromagnetic fi elds such as mobile phones, mobile base stations, cordless phones, wi-fi routers, and power lines. therefore,...
