  1. 26. Development of a Simulation Model for Combined PVT and Ground Source Heat Pump Systems : A TRNSYS Model Created for Commercial Use

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

    Author : HANNA OLAUSSON; EMMA WERNIUS; [2021]
    Keywords : Electrify everything; Solar assisted heat pump; Solar Energy; TRNSYS; Elektrifiera allt; solassisterad värmepump; Solenergi; TRNSYS;

    Abstract : The Swedish government has set a target of a 100% renewable electricity system by 2040. To reach this goal, many actions have to be undertaken. Electrification of buildings is one action to be undertaken as the residential sector accounts for a large share of greenhouse gas emissions, where the most energy efficient method is to use heat pumps.

  3. 27. 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.

  4. 28. A bonded discrete element approach to simulate loading with hydraulic mining excavators

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Carl Andersson; [2021]
    Keywords : DEM; bonded DE; granular material; hydraulic excavator; wear; Archard s wear law; LS-DYNA; simulation;

    Abstract : When operating hydraulic mining excavators the loading equipment is exposed to harsh conditions which lead to extensive wear of the equipment, especially the bucket and bucket teeth. Simulations are used to better understand the wear development and to evaluate new methods to operate excavators more efficiently. READ MORE

  5. 29. Gender differences in debt collection

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

    Author : ARMAN KARÉGAR; [2021]
    Keywords : Debt collection; Debt collection measures; Human psyche; Risk-taking; Status; Regression; Machine learning; Open banking; Inkasso; Inkassoåtgärder; Mänskligt psyke; Risktagande; Status; Regression; Maskininlärning; Open banking;

    Abstract : From the perspective of debt collectors, the goal of debt collection processes is to maximize the chances of a debt being repaid, while minimizing the time to repayment taking place. The purpose of this thesis is to investigate what measure that is most commonly leading to debt being repaid within 30 days. READ MORE

  6. 30. Mitigating garbage collection in Java microservices : How garbage collection affects Java microservices andhow it can be handled

    University essay from Mittuniversitetet/Institutionen för informationssystem och –teknologi

    Author : Amanda Ericson; [2021]
    Keywords : Garbage collector; Microservice; Docker; docker-compose; CMS; G1GC; Shenandoah GC; ZGC;

    Abstract : Java is one of the more recent programming languages that in runtime free applications from manual memory management by using automatic Garbage collector (GC) threads. Although, at the cost of stop-the-world pauses that pauses the whole application. READ MORE
