This study investigates the fire safety problem of a smoke detection system in terms of the probable response of light scattering photoelectric smoke detectors. In particular, response characteristics of the smoke detectors were studied experimentally in a test chamber described in UL268, with cotton wick generated fire smoke flowing at a velocity between of 0.5 ms and 3 ms. Measurements of a ‘...

Bacteriorhodopsin (BR) films are oriented and deposited on indium tin oxide conductive glass by using electrophoretic sedimentation and Langmuir-Blodgett methods to construct sandwich-type photocells, respectively. The pulse response photoelectric signal of the BR photocell under pulsed laser and the differential response photoelectric signal under irradiation of interval light are measured. Th...

The development and applications of transition metal carbides, nitrides carbonitrides, commonly denoted as MXenes, have during the last few years rapidly expanded in various technological fields owing to their unique controllable properties. These materials exhibit competing performance comparing with traditional created numerous opportunities for technology markets. Taking advantage excellent ...

The overall scope of this project funded by the US Department of Energy (DOE) is to recommend means of reducing barriers to the wide spread use of lighting controls for commercial/industrial (C/I) applications using fluorescent systems. It is important to note that this project is focused on load-shed applications and photoelectric dimming where energy savings and energy management are of centr...

In this paper we demonstrate the utility of fusing energy-resolved observations of Compton scattered photons with traditional attenuation data for the joint recovery of mass density and photoelectric absorption in the context of limited view tomographic imaging applications. We begin with the development of a physical and associated numerical model for the Compton scatter process. Using this mo...

Arterial stiffness is considered an increasingly important biomarker in the evaluation of cardiovascular risk. The gold standard for assessment of arterial stiffness is measurement of aortic pulse wave velocity (PWV). The aim of the present study is to establish a new method for measurement of aortic PWV by using Photoelectric technique coupled with ECG. We studied 36 healthy male subjects betw...

[Purpose] The purpose of this study was to investigate the concurrent validity and test-retest reliability of the recently introduced OPTOGait Photoelectric Cell System for the assessment of spatio-temporal parameters of gait. [Subjects] Twenty healthy young adults (mean age = 27.35, SD = 7.4) were asked to walk 3 times on walkway at a comfortable speed. [Methods] Concurrent validity was assess...
