  1. 1. Black Box Optimization Framework for Reinsurance of Large Claims

    Master-uppsats, Stockholms universitet/Statistiska institutionen

    Författare :Sina Mozayyan; [2022]
    Nyckelord :augmented Lagrangian; constraint optimization by linear interpolation; derivative-free black box optimization; DIRECT L ; evolutionary optimization; NLopt package; mean-variance premium principle; risk management; Solvency II;

    Sammanfattning : A framework for optimization of reinsurance strategy is proposed for an insurance company with several lines of business (LoB), maximizing the Economic Value of purchasing reinsurance. The economic value is defined as the sum of the average ceded loss, the deducted risk premium, and the reduction in the cost of capital. LÄS MER

  3. 2. Improving Knee Cartilage Segmentation using Deep Learning-based Super-Resolution Methods

    Master-uppsats, KTH/Medicinteknik och hälsosystem

    Författare :Max Kim; [2021]
    Nyckelord :Deep learning; knee cartilage; segmentation; super-resolution; Djupinlärning; knäbrosk; segmentering; superupplösning;

    Sammanfattning : Segmentation of the knee cartilage is an important step for surgery planning and manufacturing patient-specific prostheses. What has been a promising technology in recent years is deep learning-based super-resolution methods that are composed of feed-forward models which have been successfully applied on natural and medical images.

  4. 3. Design of equalization filter for non-linear distortion of the loudspeaker array with listener's movement

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Akshaya Ravi; [2018]
    Nyckelord :;

    Sammanfattning : The importance of the real-time virtual auditory environment is dependent on the fidelity of reproducing the sound. The loudspeaker array provided with its ideal response is suitable for the sound reproduction. However, there exists frequency and phase distortions in the loudspeaker response that cause audible artifacts at the listener's ears. LÄS MER

  5. 4. Accuracy in Swedish unsegmented and segmented rating curves : Accounting for measurement uncertainty and heteroscedasticity

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Mattias Sörengård; [2016]
    Nyckelord :Rating curve; Non-linear-regression; Projection variable method; river discharge; gauging station; stage; uncertainty; validation; Overparametrization; overfit; hydrology;

    Sammanfattning : River discharge estimation is the basic hydrological information for most hydrological applications in various socioeconomic planning. Increasing the accuracy of the traditional rating curve in relation to river discharge estimation would be very valuable to hydrological applications. LÄS MER

  7. 5. The Equity Premium Puzzle post the Financial Crisis

    Master-uppsats, Lunds universitet/Nationalekonomiska institutionen

    Författare :Bergsveinn Snorrason; Ívar Alfreð Grétarsson; [2011]
    Nyckelord :Equity Premium Puzzle; Survivorship Bias; Non-linear interpolation; Risk aversion; Bond; Equity; Business and Economics;

    Sammanfattning : The purpose of this paper is to take a closer look at the equity premium puzzle which is one of the most intriguing puzzles in economics and has been challenging researchers for the last 25 years since Mehra and Prescott first introduced the puzzle. It refers to the empirical fact that risky equity has been outperforming default free debt with about 6 percentage points for the U. LÄS MER
