  2. 1. Characterisation and Some Statistical Aspects of Univariate and Multivariate Generalised Pareto Distributions

    Author : Nader Tajvidi; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; generalised Pareto distribution; multivariate extreme value theory; multivariate Pareto distribution; small sample properties; Bartlett s correction; maximum likelihood; statistical computations; simulation AMS 1991 subject classification: 62F11; 62E20; 60F17; 65U05; 62E20;

    Abstract : Extreme value theory is about the distributions of very large or very small values in a time series or stochastic process. This has numerous applications connected with environmental science, civil engineering, materials science and insurance. READ MORE

  4. 2. On Development Planning of Electricity Distribution Networks

    Author : Viktoria Neimane; KTH; []
    Keywords : Electric power systems; electricity distribution; planning; risk management; network optimization;

    Abstract : Future development of electric power systems must pursue anumber of different goals. The power system should beeconomically efficient, it should provide reliable energysupply and should not damage the environment. At the same time,operation and development of the system is influenced by avariety of uncertain and random factors. READ MORE

  6. 4. On Quality in Radiotherapy Treatment Plan Optimisation

    Author : Hunor Benedek; Lund Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Pareto optimisation; Pareto fronts; Dose prediction; Machine learning; Deliverable treatment plans; Volumetric modulated arc therapy; IMRT; patient-specific plan quality; plan quality; Multi Criteria Optimisation; Automated Treatment Planning;

    Abstract : Radiotherapy is one of the essential treatments used in the fight against cancer. The goal of radiotherapy is to deliver a high dose of ionising radiation to the tumour volume and at the same time minimise the effect on healthy tissue by reducing the radiation to critical organs.

  7. 5. Moment Estimation Using Extreme Value Methods

    Author : Joachim Johansson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Pareto distribution; mean estimation; heavy tailed distributions; telecommunication; m -dependence; superpopulation sampling; peaks over threshold; telecommunication;

    Abstract : The thesis is composed of three papers, all dealing with the application of extreme value methods to the problem of moment estimation for heavy-tailed distributions. In Paper A, an asymptotically normally distributed estimate for the expected value of a positive random variable with infinite variance is introduced. READ MORE
