  3. 2. Influence of Genes and Post-translational Modifications in the Pathogenesis of Light Chain Amyloidosis

    Författare :Stina Enqvist; Per Westermark; Robert Kisilevsky; Uppsala universitet; []
    Nyckelord :MEDICINE; MEDICIN; Medicine; medicin;

    Sammanfattning : Amyloid is formed when a normally soluble protein undergoes conformational changes that results in self-aggregation. The pathogenic protein in light chain amyloidosis is an immunoglobulin light chain produced by a plasma cell clone mainly in the bone marrow. LÄS MER

  4. 3. Radiation Therapy Patient Scheduling: An Operations Research Approach

    Författare :Sara Frimodig; Per Enqvist; Jan Kronqvist; Mats Carlsson; Willem-Jan van Hoeve; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Radiation therapy scheduling; patient scheduling; multi-appointment scheduling; operations research; integer programming; constraint programming; column generation; Schemaläggning; strålterapi; operationsanalys; heltalsprogrammering; villkorsprogrammering; kolumngenerering; Optimeringslära och systemteori; Optimization and Systems Theory;

    Sammanfattning : The manual scheduling of patients for radiation therapy is difficult and labor-intensive. With the increase in cancer patient numbers, efficient resource planning is an important tool to achieve short waiting times and equal right to care. This thesis studies an operations research approach to the radiation therapy scheduling problem.

  5. 4. Dynamic Optimization for Agent-Based Systems and Inverse Optimal Control

    Författare :Yibei Li; Xiaoming Hu; Per Enqvist; Yishao Zhou; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Inverse optimal control; formation control; differential game; credit scoring; Mathematics; Matematik;

    Sammanfattning : This dissertation is concerned with three problems within the field of optimization for agent--based systems. Firstly, the inverse optimal control problem is investigated for the single-agent system. Given a dynamic process, the goal is to recover the quadratic cost function from the observation of optimal control sequences. LÄS MER
