    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal analysis methods; computerized cardiac auscultation system; phonocardiographic PCG signal; mitral insufficiency MI ; time- and cost-saving; Medical engineering; Medicinsk teknik;

    Abstract : The aim of this thesis work has been to develop signal analysis methods for a computerized cardiac auscultation system, the intelligent stethoscope. In particular, the work focuses on classification and interpretation of features derived from the phonocardiographic (PCG) signal by using advanced signal processing techniques. READ MORE

  2. 2. Applanation Resonance Tonometry for Intraocular Pressure Measurement

    Author : Per Hallberg; Olof A. Lindahl; Anders Eklund; Christina Lindén; Per Ask; Umeå universitet; []
    Keywords : Physics; Resonance; applanation; tonometry; glaucoma; Goldmann; biomechanical; Intraocular; ART; Fysik; fysik; Physics;

    Abstract : Elevated intraocular pressure (IOP) is one of the major risk factors for glaucoma. Since glaucoma is a leading cause of blindness, reliable methods for measuring the IOP are important. This doctoral dissertation presents a new method, applanation resonance tonometry (ART), for measurement of IOP. READ MORE

  3. 3. Ethical Issues in Cardiology Patients' views of information and decision-making

    Author : Anders Ågård; Medicinsk etik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Praktisk filosofi; estetik; metafysik; kunskapsteori; ideologi; ideology; decision-making; information disclosure; aesthetics; metaphysics; epistemology; ethics; Kardiovaskulära systemet; Systematic philosophy; Cardiovascular system; interview; atypical chest pain; acute myocardial infarction; cardiopulmonary resuscitation; implantable cardioverter defibrillator; heart failure; patient-caregiver communication; patient preference; informed consent;

    Abstract : The over-riding aim of this thesis was to obtain a deeper understanding of the way patients with cardiac problems view both information related to their health and medical decisions and their role in decision-making processes. An important objective was to identify reasons why patients do not ask for or assimilate information or why they do not want or feel that they are able to influence medical decisions. READ MORE

  4. 4. Project work, independence and critical thinking

    Author : Anders Eklöf; Torgny Ottosson; Lars-Erik Nilsson; Per-Olof Erixon; Högskolan Kristianstad; []

    Abstract : The direct variable costs for heat and electricity production based on solid biomass fuel combustion is approximately 3-5 times lower than the costs in a fossil fuel-oil based boiler in Sweden. In addition waste derived biomass fuels are typically much cheaper than biomass not classified as waste. READ MORE
