  1. 1. COMPARISON OF MULTI-CRITERIA OPTIMIZATION IN TWO DIFFERENT TREATMENT PLANNING SYSTEMS

    Master-uppsats,

    Författare :Anna Lindström; [2021-05-10]
    Nyckelord :Medical physics; Multi-criteria optimization; Pareto front; volumetric modulated arc therapy; head and neck cancer; prostate cancer;

    Sammanfattning : Purpose: The purpose with this study was to compare multi-criteria optimization (MCO) for volumetric modulated arc therapy (VMAT) treatment plans in two different treatment planning systems. Theory: When performing treatment planning prior to radiation therapy it is important to prioritize between absorbed dose to target and absorbed dose to organs at risk (OAR). LÄS MER

  2. 2. EVALUATION OF RADIATION DOSES USING CONE BEAM COMPUTED TOMOGRAPHY IN ENDOVASCULAR AORTIC REPAIR AND SCOLIOSIS PROCEDURES

    Master-uppsats,

    Författare :Louise Strandberg; [2021-04-06]
    Nyckelord :Medical physics; Cone beam CT; CT; EVAR; scoliosis; radiation dose; effective dose;

    Sammanfattning : Purpose: The study includes the two areas, vascular surgery and orthopedics, and focuses on endovascular aortic aneurysm repair (EVAR) and scoliosis procedures. EVAR procedures contribute to a high radiation dose to the patient and for scoliosis procedures, it is often young girls that are undergoing surgery. LÄS MER

  3. 3. Quantum Portfolio Optimization : a Multi-Level Perspective Study of the Swedish Fund Management Industry

    Master-uppsats, KTH/Industriell ekonomi och organisation (Inst.); KTH/Industriell ekonomi och organisation (Inst.)

    Författare :Olle Malmberg; Joakim Wellenstam; [2021]
    Nyckelord :Quantum computers; portfolio optimization; multi-level perspective; technological transition; finance; socio-technical; Kvantdatorer; portföljoptimering; multi-level perspective; teknisk omvandling; finans; socio-teknisk;

    Sammanfattning : In recent years, quantum computers have achieved new levels of sophistication and are by some estimates only a few years from being used in production. A growing body of literature points toward their potential uses within various industries, with the finance industry identified as exceptionally full of prospective applications. LÄS MER

  4. 4. Generalizations of the Mandelstam-Tamm Quantum Speed Limit

    Master-uppsats, Stockholms universitet/Fysikum

    Författare :Niklas Hörnedal; [2021]
    Nyckelord :Quantum Information; Quantum Speed Limits; Unitary Dynamics; Time-Optimization; Mandelstam-Tamm;

    Sammanfattning : Quantum speed limits are lower bounds on the evolution time for quantum systems. In this thesis, we consider closed quantum systems. We investigate how different principal bundles offers a geometrical method for obtaining generalizations of the Mandelstam-Tamm quantum speed limit for mixed states. LÄS MER

  5. 5. Development of a novel quantitative PCR analysis method for HIV-1

    Master-uppsats, Lunds universitet/Tillämpad biokemi; Lunds universitet/Teoretisk kemi

    Författare :Anna-Malin Hallberg; [2021]
    Nyckelord :HIV; PCR; primers; probes; virus; detection; blood plasma; pathogen; biological pharmaceutical; protein-based pharmaceutical; genotype; subtype; RT qPCR; extraction; TaqMa; RNA virus; cross-dimer; applied biochemistry; tillämpad biokemi; Biology and Life Sciences; Technology and Engineering; Chemistry;

    Sammanfattning : Biological pharmaceuticals are the answer to many severe diseases of today’s society. Some of these are protein-based drugs and can be produced from human blood plasma. In order to guarantee the safety of patients, absence of any pathogens needs to be ensured. LÄS MER
