  1. 6. Performance Evaluation of a Photovoltaic/Thermal (PVT) Collector with Numerical Modelling

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

    Author : Mila Ebrahim; [2021]
    Keywords : Solar energy; Renewable energy; Photovoltaic thermal collector; PV Thermal; PVT Collector; Performance; Numerical modelling; COMSOL Multiphysics; Ground Source Heat Pump; Solenergi; Förnybar energi; kominerad solcell solfångare; PVT panel; Prestanda; Numerisk modellering; COMSOL Multiphysics; Bergvärme;

    Abstract : 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.

  3. 7. Treatment of dissolved metals in highway runoff water : Pilot-scale trial with four reactive filter media and sand filter

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Serena Bianchi; [2021]
    Keywords : stormwater treatment; metal removal; adsorption; reactive filter media; sand filtration; Petrit-T; Polonite; D-Rainclean; Filtralite-P; de-icing salt; pressure drop; filter clogging; rening av dagvatten; avl ̈agsnande av metaller; adsorption; reaktiva filterme- dier; sandfiltrering; Petrit-T; Polonite; D-Rainclean; Filtralite-P; avisningssalt; tryckfall; filterstoppning;

    Abstract : The increasing highway traffic is leading to higher and higher levels of pollutants in the stormwater, such as suspended solids, metals, oils, nutrients and PAH. This runoff water causes the degradation of water bodies quality, leading to increased interest in the treatment of highway runoff for the removal of contaminants. READ MORE

  4. 8. Test Equipment for Physical Testing of Vibration Isolator

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

    Author : ADAM ALVETEG; MARKUS JOHANSSON; [2021]
    Keywords : Test rig; vibration isolator; hysteresis; Testrigg; vibrationsisolator; hysteres;

    Abstract : Vibrations is a phenomenon that can cause problems to systems if not dealt with. In heavy duty trucks, vibrations are mainly caused by uneven roads and from the combustion engine. Vibrations can damage components, reduce their service life and cause discomfort for the driver.

  5. 9. Study of different methodologies to determine relative dielectric constant of given substrate using fabrication, modelling and measurement strategies

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Anders Lundberg; [2021]
    Keywords : Relative dielectric constant; relative permittivity; PCB substrate material;

    Abstract : In this thesis, different methods for measuring the relative dielectric constant is investigated using simulations and experimental approaches. The first method is known as the S-parameter inversion method. In this method formulae is used to calculate the characteristic impedance of the microstrip line from measured S-parameters. READ MORE

  6. 10. Feasibility of adaptive SBRT of prostate cancer: Investigating uncertainties in AI-driven and CBCT-guided online adaptive radiotherapy

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Sevgi Emin; [2020]
    Keywords : Medicine and Health Sciences;

    Abstract : Purpose: Recent developments in external radiotherapy and its utilization with artificial in- telligence (AI) enables advanced treatment plans for a range of different disease sites. By adapting to the anatomy of the day, target coverage can be ensured while sparing more healthy tissue. READ MORE
