introduction: this study seeks to discuss the light wave transport characteristics variation along the pericardium meridian under different pressures. methods: we selected 36 healthy students at the school for this study, tied up the desktop blood pressure cuff onto subjects’right proximal arms, fixed the detection probe immovably on the neiguan (pc6) acupoint and the reference point which was ...

Introduction: Measurement of the complex 3D radiation dose distribution created with advanced radiotherapy techniques such as IMRT and SRS became very important. Polymer gel dosimetry (PGD) is proposed method to recording this dose distribution. MRI, X-ray CT, ultrasound, spectrophotometry and optical CT scanners can be used for readout of Polymer gel dosimeters. Although MRI i...

Temperature measurement in microwave systems is essential for thermally driven processes, namely, catalytic reactions and ceramic sintering. Although, the application of direct thermometry methods, namely, thermocouples, have been commonly articulated in the available literature, however, contacted temperature measurement mechanisms have aroused concerns associated with the disruption of the el...

The nature of electro-optical equipment in various industries and the pursuit of the goal of reducing costs demand high reliability on the part of electro-optical systems. In this respect, reliability improvement could be addressed through a reliability allocation problem. Subsystem reliability must be increased such that the requirements as well as defined requisite functions are ensured in ac...

in this paper, based on the coupled-mode and carrier rate equations, a dynamic model and numerical analysis of a multi quantum well (mqw) chirped distributed feedback semiconductor optical amplifier (dfb-soa)  all-optical flip-flop is precisely derived. we have analyzed the effects of strains of qw and mqw and cross phase modulation (xpm) on the dynamic response, and rise and fall times of the ...

data transmission in optical systems and increased transmission distance capacity benefit by using optical amplification wavelength division multiplexing (wdm) technology. the combination of four waves (fwm) is a non-linear effect in the wavelength division multiplex (wdm), when more than two wavelengths of light in a fiber launch will occur. fwm amount depends on the channel, the channel spaci...
