measurement of the stroke volume and its changes over time can be very helpful for diagnosis of dysfunctions in the blood circulatory system and monitoring their treatments. impedance cardiography (icg) is a simple method of measuring the stroke volume based on changes in the instantaneous mean impedanceof the thorax. this method has received much attention in the last two decades because it is...

1 Based on “Portable Integrated Multi-Signal Patient Monitoring System ", by M. El Korek, R. Aloul, T. Landolsi, A.R. Al-Ali, and Y. Al-Assaf which appeared in the 3rd International Conference on Innovations in Information Technology (IIT06). © [2006] IEEE. Abstract—In this paper, we propose a wireless stand-alone, embedded system design that integrates the monitoring of three biomedical parame...

As we strive to better understand and manage risks to human health and ecosystems, the demands on environmental monitoring are increasing. Stricter regulations and a greater public awareness of environmental issues bring requirements to monitor an ever-wider range of analytes in air, water and soil, and to do so with greater frequency and accuracy. Meanwhile, operators are looking to contain th...

Monitoring air pollution including the contents of VOC, O(3), NO(2), and dusts has attracted a lot of interest in addition to the monitoring of water contamination because it affects directly to the quality of living conditions. Most of the current air pollution monitoring stations use the expensive and bulky instruments and are only installed in the very limited area. To bring the information ...

  A novel compact fiber-coupled NIR system based on a DFB diode laser source is employed as a portable and sensitive gas sensor for trace detection of combustion pollutant molecules. We demonstrate the performance of such an NIR gas sensor by tracing the absorption lines of CO and CH4 using 2f-WMS technique at moderate temperature of T ~ 600°C in the recuperator channel of an industrial furnace...
