The activity concentrations of natural radionuclides in soils from the area affected by uranium mining at Stara Planina Mountain in Serbia were studied and compared with the results obtained from an area with no mining activities (background area). In the affected area, the activity concentrations ranged from 1.75 to 19.2 mg kg(-1) for uranium and from 1.57(More)
This paper presents a low power implementation of the algorithms for QRS complex detection in FPGA technology. We used cases of Balda and Pan-Tompkins algorithms for the case study. The optimization methodology is based on the use of heterogeneous logic blocks, pipelining, the variable code word lengths, on chip reorganizing of logic blocks and the control(More)
In this paper we describe GEPSUS-W, a wearable system for hazardous gases dispersion simulation in case of manmade accidents. The system architecture, simulation methodology and preliminary results are elaborated. Emphasis is given to real-time embedded systems that allow automatic data entry and on the spot responder interaction with situations. The(More)
Activity concentrations of main terrestrial radioisotopes (226)Ra, (232)Th and (40)K were measured in geological samples collected in Libya's Jabal Eghei area, in order to contribute to the establishment of a baseline map of the environmental radioactivity levels and to estimate the associated environmental risk to the population. Activity concentrations(More)
The Wavelet Transform in its discrete form has been applied to a wide range of biomedical signals by now. Typically, its calculation is performed off-line and calculation systems suffer from limited autonomy, bulkiness and obtrusiveness. A surge in industrial, research and academic interest into telemedicine and medical embedded systems, has been noticed(More)
