1. 1. Electrical Bioimpedance Cerebral Monitoring : From Hypothesis and Simulation to First Experimental Evidence in Stroke Patients

   Författare :Seyed Reza Atefi; Fernando Seoane; Michael Bodo; Kaj Lindecrantz; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Biompedance Spectroscopy; Stroke; Hemorrhage; Ischemia; FEM; HFSS; Electrical Potentials; Människan i vården;

   Sammanfattning : Stroke is amongthe leading causes of death worldwide and requires immediate care to prevent death or permanent disability. Unfortunately, the current stateof stroke diagnosis is limited to fixed neuroimaging facilities that do not allow rapid stroke diagnosis. LÄS MER

3. 2. Effects of electrical accidents : occupational and health perspectives

   Författare :Lisa Rådman; Magnus Thordstein; Håkan Olausson; Kerstin Norman; Finn Nilson; Örebro universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Electrical accident; Neurosensory symptoms; No-let-go phenomenon; Pain; Voltage; Quantitative sensory testing;

   Sammanfattning : Professionals working in the electrical industry are at risk of accidental injuries caused by electricity. Electrical accidents can cause persistent neurological symptoms, previously mainly described in patients whose injuries were initially extensive. LÄS MER

4. 3. Wireless Sensor Networks for Development : Potentials and Open Issues

   Författare :Marco Zennaro; Björn Pehrson; Andreas Kassler; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telecommunication; Telekommunikation;

   Sammanfattning : Wireless Sensor Networks (WSNs) provide a way to bridge the gap between the physical and the virtual worlds. They promise unprecedented abilities to observe and understand large-scale, real-world phenomena at a fine spatial-temporal resolution. LÄS MER

5. 4. On Signal Dependent Basis Functions, Estimation of Event Related Potentials and Multiple Window Spectrum Analysis

   Författare :Maria Hansson; Institutionen för elektro- och informationsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal processing; spectrum analysis; multiple windows; anaesthesia; Nb-trough; damped sinusoids; single ERP; Signal dependent basis functions; Event Related Potentials;

   Sammanfattning : The three parts of this thesis are different examples of utilization of signal dependent basis functions in the estimation procedure. The first part surveys a number of parametric methods applied to estimation of single ERP (P300). LÄS MER

7. 5. Surface Charge Dynamics on Polymeric Insulating Materials for High Voltage Applications

   Författare :Shahid Alam; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HVDC insulation.; gas neutralization; decay rate; Surface charging; electrical conductivity; surface potential; charge transport; ambient pressure;

   Sammanfattning : To meet increasing demands in electric energy, it is essential to enhance production of electricity from renewable energy sources (solar, wind and hydro). Such generation sites, however, are usually separated from consumption sites by long distances. LÄS MER
