7. Performance Investigation & Gas Exchange Assessment of Exhaust Piston–assisted Turbocharged Engine (EPTE) Concept : A simulation-based assessment
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : There is an increasing stringency in the emission legislation within the transport industry along with ambitious performance demands from the customer side. These have pushed the vehicle manufacturers and relevant component suppliers to develop and integrate a wide portfolio of engine technologies. LÄS MER
8. Optimering av dubbelspaltigt värmefönster
Kandidat-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : Utvecklad för att bibehålla termisk komfort och minska exergianvändningen, Free Heat Exchange Window [FHEW] är en fönsterdesign som är tänkt att ersätta konventionella värmesystem i bostäder och kontorsbyggnader. Baserat på dubbelspaltkonceptet kommer fönstret utgöra en värmekälla under kalla vinterdagar och en värmesänka under varmare sommardagar. LÄS MER
9. Analysis of fault performanceof heat pump-PV systems
Master-uppsats, Uppsala universitet/Institutionen för samhällsbyggnad och industriell teknikSammanfattning : Air source heat pumps coupled with a photovoltaic system is onefeasible technology to reduce the emissions from the building sector.These systems usually have an auxiliary heating device that is able tocover the whole heat demand on its own.

10. Improving cell secretome analysis and bacteria evolution by means of acoustophoresis
Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Sammanfattning : In both, cell secretome analysis and bacteria evolution, controlled handling of particles with a few to sub-micrometers in size and media exchange are inevitable in order to investigate body fluid’s proteins or change the surrounding culture conditions for pivoted evolution. Typically, nanofiltration and ultra-centrifugation are employed which can lead to cell damage, need large sample volumes and have a high sample loss. LÄS MER
