1. Comparative Analysis of In-Body to Out-Body Wireless CommunicationModules: Test Design and PerformanceEvaluation
Master-uppsats, Högskolan i Halmstad/Akademin för informationsteknologiSammanfattning : Wireless communication for biomedical equipment is rapidly improving with the invention of new technologies. Due to the absence of cables, wireless technology is a growing area of interest for biomedical applications. As technology advances, many gadgets are becoming smaller and more portable. LÄS MER
2. Förbättring av energieffektiviteten för villor genom att implementera grund geotermisk ventilation
Kandidat-uppsats, Jönköping University/JTH, Byggnadsteknik och belysningsvetenskapSammanfattning : Introduction: The world is facing an economic crisis that has led to high energy prices in the EU. These high energy prices have been a contributing factor to the challenging economic situation in Sweden, affecting businesses, industries, and households. EU countries have limited access to energy and rely mostly on imports. LÄS MER
3. Avluftkanalers inverkan på energiförluster i flerbostadshus : En parameterstudie i Comsol Multiphysics 6.1
Master-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)Sammanfattning : Den globala uppvärmningen blir en alltmer central fråga i samhället i takt med att det 1,5°C- mål som sattes i Parisavtalet kommer allt närmre. Mot bakgrund av denna växande oro har EU under energikrisen 2022/2023 enats om att främja energieffektivisering, och poängterar dess vikt för att bland annat uppnå en hållbar energiproduktion och minska den negativa klimatpåverkan en stor energikonsumtion medför.

4. Characterisation of Ionic Liquid doped Polybenzimidazole Membranes for Application in High-Temperature Proton Exchange Membrane Fuel Cells
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : In this study four membranes were tested and evaluated against each other for use in high-temperature proton exchange membrane fuel cell (HT-PEMFC) applications. A phosphoric acid (PA) doped polybenzimidazole (PBI) membrane, was used as a reference as the current state-of-the-art. LÄS MER
5. Plume-Spacecraft Interaction Analysis : Study on the Plume Effects of Hall-Effect Thrusters (HET) and High-Efficiency Multistage Plasma Thrusters (HEMPT).
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Plume-spacecraft interactions play an important role in the performance and integrity of spacecraft during their missions in space. The study encompasses a thruster’s plume simulation and its impact on spacecraft geometries to understand and predict the effects and consequences of the impingement on spacecraft surfaces, such as erosion, contamination, forces, and torques.
