    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal processing; morphology classification; QRS detection; ischemia; body position changes; electrogram; ECG; electrocardiogram; clustering; classification; Detection; sensing;

    Sammanfattning : Signal processing can be used to condition medical signals to facilitate their interpretation, and to extract clinically important information. The purpose of the present doctoral thesis is to put forward solutions to certain problems encountered in the processing of electrocardiac signals. LÄS MER

  3. 2. Brain tumors in children - National population-based studies on classification, diagnostics and long-term follow-up

    Författare :Elizabeth Schepke; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pediatric CNS tumors; population-based; DNA methylation; profiling; CNS-PNET; re-evaluation; incidence rate; long-term outcome; classification; Pediatric CNS tumors; Population-based; DNA methylation; Profiling; CNS-PNET; Re-evaluation; Incidence rate; Long-term outcome; Classification;

    Sammanfattning : Although the prognosis for pediatric tumors of the central nervous system (CNS) has improved over time it is urgent to reduce mortality and improve long-term quality of life for survivors. With this aim, the first step is to identify the correct diagnosis in order to choose the right therapy and avoid unnecessary treatment. LÄS MER

  4. 3. Automated Subject Classification of Textual Documents in the Context of Web-Based Hierarchical Browsing

    Författare :Koraljka Golub; Institutionen för elektro- och informationsteknik; []

  5. 4. Ecotoxicological classification of ash materials

    Författare :Sara Stiernström; Magnus Breitholtz; Christina Rudén; David Bendz; Olof Berglund; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ecotoxicity; ash; classification; leaching; Waste Framework Directive; CLP-Regulation; Hazard Identification; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Incineration of waste is increasing in the EU. However, in the incineration process, both fly and bottom ash materials are generated as waste that requires further action. A common goal throughout Europe is to find ways to utilize ash materials in an environmentally and economically efficient manner in accordance with the current legislation. LÄS MER

  7. 5. Molecular Classification of Bladder Cancer

    Författare :Gottfrid Sjödahl; Bröstcancer-genetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bladder cancer; Subtype; Classification;

    Sammanfattning : Decisions in the treatment of bladder cancer today are based on clinical and pathological risk variables such as tumor stage and tumor grade. The importance of these conventional risk variables is well documented since more than 10 years, and they are used routinely in the clinics. LÄS MER
