  1. 36. Neural Network Approaches To Survival Analysis

    Författare :Jonas Kalderstam; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Survival Analysis; Artificial Neural Networks; Machine Learning; Genetic Algorithms; Evolutionary Algorithms; Fysicumarkivet:2015:Kalderstam;

    Sammanfattning : Predicting the probable survival for a patient can be very challenging for many diseases. In many forms of cancer, the choice of treatment can be directly impacted by the estimated risk for the patient. This thesis explores different methods to predict the patient's survival chances using artificial neural networks (ANN). LÄS MER

  3. 37. Statistical methods for register based studies with applications to stroke

    Författare :Anita Lindmark; Marie Eriksson; Xavier de Luna; Eva-Lotta Glader; Saskia le Cessie; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Registers; quality of care; socioeconomic status; hospital performance; stroke; mediation; sensitivity analysis; truncation; censoring; Statistics; statistik;

    Sammanfattning : This thesis adds to the area of register based research, with a particular focus on health care quality and (in)equality. Contributions are made to the areas of hospital performance benchmarking, mediation analysis, and regression when the outcome variable is limited, with applications related to Riksstroke (the Swedish stroke register).

  4. 38. Longser Antar Pulau: Indonesian cultural politics and the revitalisation of traditional theatre

    Författare :Jörgen Hellman; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; etnografi; socialantropologi och etnologi: Java;

    Sammanfattning : The dissertation investigates the ambiguous role that cultural politics have played in the process of formulating an Indonesian national identity. Three case studies exemplify how cultural politics have been used by the state for the purpose of disciplining ethnic sentiments, at the same time as other groups have used the same discourse to express ideas contrary to the government controlled ideology.

  5. 39. On reliability modelling of ageing equipment in electric power systems with regard to the effect of maintenance

    Författare :Tommie Lindquist; Prof. Roland Eriksson; Dr. Lina Bertling; Docent Carl-Ejnar Sölver; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical power technology; Maintenance; reliability modelling; electrical power systems; ageing; failure mechanisms; Elkraftteknik; Electric power engineering; Elkraftteknik;

    Sammanfattning : Power system maintenance optimisation involves obtaining the minimum total costs, including preventive and corrective maintenance costs and the cost of failures for both supplier and customer. To calculate the cost of failure, information is needed about the equipment reliability characteristics. LÄS MER

  7. 40. In Vivo Active Drug Uptake and Efflux at the Blood-Brain Barrier : With Focus on Drug Transport Interactions

    Författare :Muhammad Waqas Sadiq; Margareta Hammarlund-Udenaes; Sven Björkman; N. Joan Abbott; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Blood-brain barrier; Active uptake transport; Microdialysis; P-glycoprotein; Drug interactions; Species differences; Pharmacokinetics; Pharmacodynamics; NONMEM; Pharmaceutical Science; Farmaceutisk vetenskap;

    Sammanfattning : The blood-brain barrier (BBB) controls the movement of substances into and out of the brain. The tight junctions between endothelial cells and energy dependent transporters in the BBB influence rate and extent of drug distribution to the brain. LÄS MER
