The main area of interest of our project is to provide solution which can be used in different areas of health care and which will be available through PDAs (Personal Digital Assistants), web browsers or desktop clients. The realized system deals with an ECG sensor connected to mobile equipment, such as PDA/Embedded, based on Microsoft Windows Mobile operating system. The whole system is based ...

The main area of interest of our Biotelemetric System is to provide solution which can be used in different areas of health care and which will be available through PDAs (Personal Digital Assistants), web browsers or desktop clients. In paper we deals with a problem of visualization of measured ECG signal on mobile devices in Real Time as well as with a solution how to solve a problem of unsucc...

We have observed 1H NMR spectra of hydrogen molecules trapped inside modified fullerene cages under cryogenic conditions. Experiments on static samples were performed at sample temperatures down to 4.3 K, while magic-angle-spinning (MAS) experiments were performed at temperatures down to 20 K at spinning frequencies of 15 kHz. Both types of NMR spectra show a large increase in the intramolecula...

This paper describes ,the cryogenic operation of partially depleted Silicon-On-Insulator inverters. As is shown, the floating operation yields a degradation of the transfer characteristics, which increases upon cooling. Additionally, at cryogenic temperatures, hysteresis effects further deteriorate the performance. These observations will be discussed in view of the cryogenic SO1 MOSFET charact...

In this study, beryllium-copper alloy was subjected to around -150° F for cold treatment and to around -300° F for cryogenic treatment and the effects of these cold and cryogenic treatments on the machinability of beryllium-copper workpieces in electro discharge machining have been investigated. Experimental results showed about 20-30 % increase in material removal rate of cold and cryogenic tr...

Following our first successful imaging experiments'-3 with high-field superconducting solenoid lenses, numerous methodological and conceptual problems remained to be solved before the specific advantages of this approach could be adequately established for high-resolution electron microscopy. These problems included: (a) incorporation of superconducting solenoid lenses and associated cryogenic ...

Impact testing methodology is findings the applications for determining the impact strength of the different materials. Oneof the most important characteristics of structural steels, toughness is assessed by the Charpy V-notch impact test. The objective of the research was to maximize the impact toughness by selecting various combinations of Charpy Impact test parameters. In this paper, experim...
