1. 1. Flexible Sector Coupling (FSC) of Electrical and Thermal Sectors via Thermal Energy Storage (TES) : A Case Study on Oskarshamn Energi

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

   Author : Raúl Calvo García; Jose María Marín Arcos; [2023]
   Keywords : Flexible sector coupling FSC ; district heating DH ; thermal energy storage TES ; heat pump HP ; capacity optimization; dispatch optimization; open-access tools; Flexibel sektorkoppling; fjärrvärme; termisk energilagring; värmepump; kapacitetsoptimering; leveransoptimering; verktyg med öppen tillgång;

   Abstract : The integration of distributed energy sources and systems is of high relevance for the transition towards a more sustainable energy system. Taking into consideration the  amount of emissions produced by the heating sector, which account for at least half of the energy demand in buildings, district heating systems have the potential to play a key role in the transition, by enabling the integration of various energy sources and provide flexible energy services to the grid.

3. 2. Expression Simplification Using E-Graphs for Interval Evaluation

   University essay from Uppsala universitet/Institutionen för informationsteknologi

   Author : Simon Björklund; [2023]
   Keywords : ;

   Abstract : Daisy is a framework for verifying and bounding the magnitudes of rounding errors introduced by floating-point arithmetic in numerical programs. As part of this, Daisy employs a rudimentary algorithm for simplifying expressions derived from the programs. READ MORE

4. 3. Adjoint optimization of a liquid-cooled heat sink

   University essay from KTH/Teknisk mekanik

   Author : Roven Pinto; [2023]
   Keywords : Adjoint method; topology optimization; porosity; OpenFOAM;

   Abstract : Improving the design of flow channels in a liquid-cooled heat sink is critical for boosting the capabilities of electronic components as well as reducing energy usage by the pump. This work explores the use of topology optimization to minimize the pressure difference across a heat sink and consequently, the energy used to supply the liquid. 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. A Comparative Study on Optimization Algorithms and its efficiency

   University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

   Author : Kareem Ahmed Sheik; [2022]
   Keywords : Optimization; Heuristic Search Algorithms; Benchmark Optimization Problems; Systematic literature review; Benchmark functions; Genetic Algorithm; Plant intelligence based optimization algorithm;

   Abstract : Background: In computer science, optimization can be defined as finding the most cost-effective or notable achievable performance under certain circumstances, maximizing desired factors, and minimizing undesirable results. Many problems in the real world are continuous, and it isn't easy to find global solutions. READ MORE
