2. 11. Risk stratification in cardiac surgery: Algorithms and applications

   Author : Johan Nilsson; Thoraxkirurgi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; orthopaedics; traumatology; Kardiovaskulära systemet; Cardiovascular system; Cardiac surgery; Statistics; Artificial neural networks; Resource utilization; Mortality; Risk factors; Kirurgi; ortopedi; traumatologi;

   Abstract : The aims of this research was to compare different risk score algorithms with regard to their validity to predict 30-day and one-year mortality after open-heart surgery, to evaluate if the preoperative risk stratification model EuroSCORE predicts the different components of resource utilization in cardiac surgery, and to systematically evaluate the accuracy and performance of artificial neural networks (ANNs) to select and rank the most important risk factors for operative mortality in open-heart surgery. Preoperative evaluation of the surgical risk is an important component in cardiac surgery. READ MORE

   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Autonomous systems; inverse optimal control; system identification; nonlinear systems; formation control; differential game; credit scoring.; Autonoma system; invers optimal styrning; system identifiering; olinjära system; formationsstyrning; differentialspel; kreditvärdering.; Optimeringslära och systemteori; Optimization and Systems Theory;

   Abstract : This dissertation is concerned with three topics within the field of optimal control and estimation in dynamical agent-based systems, with potential applications that meet both engineering and societal needs. Firstly, the inverse optimal control problem is studied. READ MORE

5. 13. Sensor-based knowledge- and data-driven methods : A case of Parkinson’s disease motor symptoms quantification

   Author : Somayeh Aghanavesi; Mark Dougherty; Mobyen Uddin Ahmed; Högskolan Dalarna; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Parkinson’s disease; motion sensors; motor symptoms; smartphone; microdata; multivariate analysis; data-driven; knowledge-driven; support vector machine stepwise regression; predictive models; Complex Systems – Microdata Analysis; Komplexa system - mikrodataanalys;

   Abstract : The overall aim of this thesis was to develop and evaluate new knowledge- and data-driven methods for supporting treatment and providing information for better assessment of Parkinson’s disease (PD).PD is complex and progressive. There is a large amount of inter- and intravariability in motor symptoms of patients with PD (PwPD). READ MORE

6. 14. Lifelong Visual Localization for Automated Vehicles

   Author : Peter Mühlfellner; Thorsteinn Rögnvaldsson; Roland Philippsen; Tom Duckett; Högskolan i Halmstad; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vision-based localization; automated vehicles;

   Abstract : Automated driving can help solve the current and future problems of individualtransportation. Automated valet parking is a possible approach to help with overcrowded parking areas in cities and make electric vehicles more appealing. In an automated valet system, drivers are able to drop off their vehicle close to a parking area. READ MORE

7. 15. In-hospital patient safety - prevention of deterioration and unexpected death by systematic and interprofessional use of early warning scoring

   Author : Gitte Bunkenborg; Anestesiologi och intensivvård; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Patient safety; Adverse event; Vital parameters; Deterioration; Early warning score; Mortality rate; Unexpected death; Clinical intervention; Adherence; Implementation; association;

   Abstract : Abstract In-hospital patient safety is at times hampered, leaving general ward patients at considerable risk of gradual, even life-threatening, deterioration. In many European clinical settings, inappropriate nursing practice of bedside monitoring and management has recently been addressed as impending to in-hospital patient safety. READ MORE
