1. 1. Improvement of anautomatic networkdrawing algorithm in thecontext of utility networks

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Hyacinthe Ménard; [2024]
   Keywords : District Heating Network; Mathematical Optimization; Python; Fjärrvärme; Optimeringslära; Python;

   Abstract : The European Union’s ambitious climate targets necessitate substantial reductions in greenhouse gas emissions, particularly within the heating and cooling sector, which accounts for a significant portion of energy consumption. District Heating and Cooling (DHC) systems emerge as a key solution for decarbonizing this sector by enabling high efficiency heat production and the integration of renewable and carbon-neutral energy sources.

3. 2. Machine Learning for State Estimation in Fighter Aircraft

   University essay from KTH/Optimeringslära och systemteori

   Author : Axel Boivie; [2023]
   Keywords : State estimation; machine learning; fighter aircraft; neural networks; long short- term memory; LSTM; sensor fusion; air data system; ADS.; Tillståndsestimering; maskininlärning; stridsflygplan; neurala nätverk; sensorfusion; luftdatasystem.;

   Abstract : This thesis presents an estimator to assist or replace a fighter aircraft’s air datasystem (ADS). The estimator is based on machine learning and LSTM neuralnetworks and uses the statistical correlation between states to estimate the angleof attack, angle of sideslip and Mach number using only the internal sensorsof the aircraft.

4. 3. Numerical simulations oflovastatin crystallization in aT-shaped 2D mixer

   University essay from KTH/Optimeringslära och systemteori

   Author : Anton Bergman; [2023]
   Keywords : ;

   Abstract : The rise of battery driven technology and the strive towards circular economy calls for the indefinite recycling of metals used in batteries. To be able to study and optimize the processes used in recycling, mathematical models are required. READ MORE

5. 4. Minimum Cost Distributed Computing using Sparse Matrix Factorization

   University essay from KTH/Optimeringslära och systemteori

   Author : Seif Hussein; [2023]
   Keywords : Applied mathematics; optimization; convex optimization; matrix factorization; sparse matrix factorization; distributed computing; linearly separable distributed computing; ADMM; alternating direction method of multipliers; tillämpad matematik; optimering; konvex optimering; matrisfaktorisering; gles matrisfaktorisering; distribuerade beräkningar; admm; alternating direction method of multipliers;

   Abstract : Distributed computing is an approach where computationally heavy problems are broken down into more manageable sub-tasks, which can then be distributed across a number of different computers or servers, allowing for increased efficiency through parallelization. This thesis explores an established distributed computing setting, in which the computationally heavy task involves a number of users requesting a linearly separable function to be computed across several servers.

6. 5. Optimal Control of An Energy Storage System Providing Fast Charging and Ancillary Services

   University essay from KTH/Optimeringslära och systemteori

   Author : Max Völcker; Hugo Rolff; [2023]
   Keywords : Optimal Control; Model Predictive Control; Dynamic Programming; State-Space Representation; Monte Carlo Simulation; Frequency Regulation; Fast Charging; Energy Storage Systems; Net Present Value; Optimal styrteori; Modell-prediktiv reglering; Dynamisk programmering; Frekvensreglering; Snabbladdning; Energilager; Nuvärde;

   Abstract : In this thesis, we explore the potential of financing a fast charging system with energy storage by delivering ancillary services from the energy storage in an optimal way. Specifically, a system delivering frequency regulation services FCR-D Up and FCR-D Down in combination with energy arbitrage trading is considered. READ MORE
