1. Performance Evaluation of a Photovoltaic/Thermal (PVT) Collector with Numerical Modelling
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : In Photovoltaic/Thermal (PVT) technology, both PV and solar thermal technology are integrated in the same module for simultaneous electricity and heat production. Research has shown that there are multiple benefits from integrating PVT collectors with a ground source heat pump (GSHP) system, since it allows for seasonal storage of thermal energy over the year.

2. Mathematical modelling of Degussa Furnace
Kandidat-uppsats, KTH/MaterialvetenskapSammanfattning : The energy demands in the world is rapidly increasing and with this, a supply nuclear power is of much interest. Nuclear fuel is relatively efficient when comparing to power sources like wind and hydropower plants. LÄS MER
3. Comparing Different Approaches for Solving Large Scale Power Flow Problems on the CPU and GPU with the Newton-Raphson Method
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Power system modelling is increasing in importance. It is vital for power system operations and transmission grid expansions, and therefore the future energy transition. The Swedish power system is under fast development to face the progress of more flexible demand, a higher share of distributed renewable sources, and updated capacities. LÄS MER
4. Investigation of Outflow Boundary Conditions for Convection-Dominated Incompressible Fluid Flows in a Spectral Element Framework
Master-uppsats, KTH/Numerisk analys, NASammanfattning : In this thesis we implement and study the effects of different convective outflow boundary conditions for the high order spectral element solver Nek5000 in the context of solving convective-dominated fluid flow problems. By numerical testing we show that the convective boundary conditions preserve the spatial and temporal convergence rates of the solver. LÄS MER
5. Utveckling av en trådlös bioelektrisk signalinsamlingsmodul
Master-uppsats, KTH/Maskinkonstruktion (Inst.)Sammanfattning : Där finns många intressanta forskningsområden kring utvecklingen av mekatroniskaproteser, ett av dessa områden berör specifikt möjligheterna till trådlöskommunikation mellan protesen och omvärlden. Huvudmålet med detta arbete var att utveckla ett trådlöst bioelektrisk signal-insamlingssystem för elektromyografiska signaler i real-tid hos patienter som har genomgått enarmamputation. LÄS MER
