21. Simulation of solidification and cooling of a casting product using COMSOL Multiphysics
Master-uppsats, Lunds universitet/Institutionen för energivetenskaperSammanfattning : In this project, the cooling and solidification processes for a Valmet Foundry product have been simulated in order to shorten the cooling time. The study has also been done in cooperation with RISE Swecast in Jönköping, as a part of finding ways to make casting procedures more energy efficient. LÄS MER
22. Catching Ash : Methodology for ash accumulation in diesel particulate filters
Master-uppsats, KTH/MaterialvetenskapSammanfattning : The diesel particulate filter captures particulate matter that is produced in the diesel engine. A small fraction of particulate matter is comprised by ash forming matter. When the combustible fraction of particulate matter is removed from the filter, the ash, which is incombustible, remains.

23. GOTTSUNDA DISTRICT CENTRE
Magister-uppsats, KTH/ArkitekturSammanfattning : IN BETWEEN GOTTSUNDA SQUARE AND A NATURE AREA IS THE NEW DISTRICT CENTER INTENDED TO BE PLACED.THE PLACE IS A POSSIBILITY THAT CREATES CONDITIONS FOR A BUILDING WHICH EXPANDS PRIDE, JOY AND OPENITY. ONE OF THE AMBITIONS IS TO CREATE A VIVID BUILDING OPENING UP TO THE SQUARE, AT THE SAME TIME THAT IT RELATES AND ENHANCES THE NEARBY BUILDING. LÄS MER
24. Partikelavlagring i ventilationssystem vid brand : Hur påverkar det igensättningen av ventilationsfilter
Kandidat-uppsats, KTH/Byggteknik och designSammanfattning : Fläkt-i-drift är ett ventilationstekniskt brandskydd, som nyttjar frånluftsfläkten för att tryckavlasta ett brandrum och därmed förhindra brandgasspridning. Ett problem för dessa system är att ventilationsfilter riskerar att sätta igen, då brandrök transporteras genom systemet. LÄS MER
25. Proposed Design and Feasibility Study of a Hybrid-Electric Propulsion System for a Ten Passenger Aircraft
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : This study aims to propose a hybridized version of a propulsion system for a 10-passenger aircraft and compare it to a conventional (reference) aircraft which uses a fossil fuelled turbofan for propulsion. The hybridized powertrain includes a fossil fuelled gas turbine, which is only used for producing electricity, coupled in a series configuration with a battery storage, that provide power to two electrically ducted fans.
