  1. 1. Value at Risk and Expected Shortfall risk measures using Extreme Value Theory

    University essay from Göteborgs universitet/Institutionen för nationalekonomi med statistik

    Author : Peter Johansson; [2019-01-22]
    Keywords : Extreme Value Theory; Generalized Pareto Distribution; Point-Over-Threshold method; risk measures; Value at Risk; Expected Shortfall;

    Abstract : Calculating risk measures as Value at Risk (VaR) and Expected Shortfall (ES) has become popular for institutions and agents in financial markets. A main drawback with these risk measures is that they traditionally assume a specific distribution, as the Normal distribution or the Student’s t distribution. READ MORE

  2. 2. Production optimization for district heating : Short-term planning of district heating grid in Gävle, Sweden

    University essay from Mälardalens högskola/Akademin för ekonomi, samhälle och teknik; Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Author : Nicolas Lindgren; Karl Brogren; [2019]
    Keywords : Short-term planning; Optimization; District heating; Linear programming; Mixed integer non-linear programming; Branch and bound; Heat storage; MATLAB; TOMLAB;

    Abstract : Energy systems with a high portion of renewable energy from wind and solar power can suffer from fluctuations in production due to weak winds or cloudy weather, which may affect the electricity price. When producing heat and power in a combined heat and power plant, an additional heat storage tank can be used to store the heat surplus which is obtained when the power production is high, and the heat demand is low.

  3. 3. Evaluation of Model-Based Design Using Rapid Control Prototyping on Forklifts

    University essay from Linköpings universitet/Reglerteknik; Linköpings universitet/Reglerteknik

    Author : Lovisa Jansson; Amanda Nilsson; [2019]
    Keywords : Rapid Control Prototyping; Model-Based Design; Forklift; Automatic control; Speedgoat; Model Predictive Control; MPC; P Controller; Models; Simulink; Matlab; Minimum Jerk Trajectory;

    Abstract : The purpose of this thesis is to evaluate Rapid Control Prototyping which is apart of the Model-Based Design concept that makes it possible to convenientlytest prototype control algorithms directly on the real system. The evaluation ishere done by designing two different controllers, a gain-scheduled P controllerand a linear Model Predictive Controller (mpc), for the lowering of the forks of aforklift. READ MORE

  4. 4. Metamodelling of a Finite Element Analysis of a Drilling Process with Replaceable Inserts

    University essay from Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Author : Samy Akrouh Ettaghadouini; [2019]
    Keywords : drilling; speed; feed; CAD; FEM; simulations; metamodel; neural network; optimization;

    Abstract : The aim of this project is to create a metamodel from a drilling tool with replaceable inserts from FEA of the machining process using MATLAB and ABAQUS. This report contains research in drilling and in metamodeling using neural networks and the work from the design of the CAD, through FEA and simulations, to the metamodeling, excluding the optimization.

  5. 5. DISTRICT HEAT PRICE MODEL ANALYSIS : A risk assesment of Mälarenergi's new district heat price model

    University essay from Mälardalens högskola/Akademin för ekonomi, samhälle och teknik; Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Author : Erik Landelius; Magnus Åström; [2019]
    Keywords : district heating; multilinear regression; Bootstrapping; Mälarenergi; weather parameters; heat prediction; statistical inference; Unscrambler;

    Abstract : Energy efficiency measures in buildings and alternative heating methods have led to a decreased demand for district heating (DH). Furthermore, due to a recent increase in extreme weather events, it is harder for DH providers to maintain a steady production leading to increased costs. These issues have led DH companies to change their price models. READ MORE
