background:: this study developed a smart co 2 detector, which attach to the general ventilation system to reduce the gas level. methods: indoor air quality measurement was performed in five selected rooms between january 2015 to february 2015 using tsi q-trak tm indoor air monitor 7575. the perceived indoor air quality conditions was gathered using questionnaires adopted from the industrial co...

The IceCube neutrino detector is built into the Antarctic ice sheet at the South Pole to measure high energy neutrinos. For this, 4800 photomultiplier tubes (PMTs) are being deployed at depths between 1450 and 2450 meters into the ice to measure neutrino induced charged particles like muons. IceTop is a surface air shower detector consisting of 160 Cherenkov ice tanks located on top of IceCube....

High sensitivity detectors for radon in air and in water have been developed. We use electrostatic collection and a PIN photodiode for these detectors. Calibration systems have been also constructed to obtain collection factors. As a result of the calibration study, the absolute humidity dependence of the radon detector for air is clearly observed in the region less than about 1.6 g/m3. The cal...

We have measured the energy spectrum of ultra-high energy cosmic rays (UHECR) with the HiRes FADC detector (HiRes-2) in monocular mode. A detailed Monte Carlo simulation of the detector response to air showers has been used to calculate the energy dependent acceptance of the air fluorescence detector. The measured spectrum complements the measurement by the HiRes-1 detector down to lower energi...

Detection of air bubbles in the blood is important for various medical treatments that use Extracorporeal Blood Circuits (ECBC), such as hemodialysis, hemofiltration and cardio-pulmonary bypass. Therefore a reliable air bubble detector is needed. This study presents the design of a new fault tolerant air bubble detector. Triple Modular Redundancy (TMR) method is used on the sensor section. A vo...

Fast reduction of blood water volume due to ultra-filtration via hemodialysis machine and critical threshold of blood water volume can result in clinical complications such as hypotension. When blood water volume reduces during hemodialysis process, the concentration of blood forming elements will increase. One of the methods for the monitoring of the concentration changes is ultrasonic speed m...

We report on analysis of coincident observation of air showers by the South Pole Air Shower Experiment (SPASE) and the Antarctic Muon and Neutrino Detector Array (AMANDA). We emphasize the response of AMANDA to muon bundles and the use of coincident events for calibration and survey of the deep AMANDA detector. This analysis is confined to data taken during 1997 when both SPASE-1 and SPASE-2 we...
