Recent years have seen a growing interest in the use of portable monitoring devices for the diagnosis of obstructive sleep apnea syndrome. These have the potential to be used in lieu of the more complicated and uncomfortable alternative, polysomnography, which has long been considered to be the gold standard for the diagnosis of this relatively prevalent condition. Following their approval in 2...

A portable laser-induced fluorescence system (total weight about 1.7 kg) has been developed for detecting the level of dissolved organic matter in water. The portable system consists of a high pulse repetition frequency (10-kHz) microchip laser at 405 nm, a reflective fluorescent probe and a broadband micro spectrometer. The stability and sensitivity of the new instrument were studied. The dete...

Distributed resource property repositories and state monitoring systems are critical components of any Grid Management Architecture, providing Grid scheduler, job/execution manager and state estimation components with accurate information about network, computational and storage resource properties and status. Without an upto-date information and monitoring service, intelligent scheduling decis...

The primary goal of long-term monitoring is the improvement of diagnostic yield. Despite the clear utility of Holter monitoring in clinical cardiology, issues of relatively low diagnostic yield, cost and inconvenience have motivated the development of ultra-portable devices referred to as ECG patch monitors. Although the "gold standard" for assessing cardiac rhythm abnormalities remains a 12-le...

On-line tools for parallel and distributed programs require a facility to observe and possibly manipulate the programs' run-time behavior, a so called monitoring system. Currently, most tools use proprietary monitoring techniques that are incompatible to each other and usually apply only to speciic target plattforms. The On-line Monitoring Interface Speciication (OMIS) is the rst speciication o...

background: exposure to loud music from sources such as portable music players (pmp), especially among adolescents, can lead to noise-induced hearing loss. the aims of this study are as follows: 1) investigate the prevalence of headphone use in iranian university students by assessing their behavior, 2) determine the type of headphones used, and 3) ascertain the type of music player used. metho...
