1. Patienters upplevelse av invasiv mekanisk ventilering och/eller lätt sedering på en intensivvårdsavdelning : En litteraturöversikt
Magister-uppsats, Röda Korsets HögskolaSammanfattning : Bakgrund: På en intensivvårdsavdelning (IVA) förekommer det ofta mekaniskt ventilerade samt sederade patienter. Detta kan vara en stressfull upplevelse både fysiskt och psykiskt för patienter. Intensivvården har funnits i ca 70 år och utvecklas varje dag. LÄS MER
2. Thermal fatigue and soldering experiments of additively manufactured hot work tool steels
Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)Sammanfattning : Modern manufacturing processes are under a never ending evolvement. Lowered manufacturing costs, higher part quality, shorter lead times and lower environmental impact are some important drivers for this development. Aluminum die casting is an effective and attractive process when producing components for e.g. LÄS MER
3. Fatigue Life Analysis of Weld Ends : Using FE-Calculations and Mechanical Testing
Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för maskinteknikSammanfattning : Fatigue life estimation of welds is a complex issue since the characteristics of each weld are unique depending on load case, geometry and properties. Fatigue life estimation on weld ends is limited and often the weakest point of a weld. LÄS MER
4. A tramming concept for a mechanical rock excavation machine
Master-uppsats, KTH/Maskinkonstruktion (Inst.)Sammanfattning : This report is the result of a thesis project at KTH in cooperation with Svea Teknik AB and Atlas Copco Mining and Rock Excavation. Atlas Copco is currently developing a family of machines for mechanical rock excavation. All machines in the family have two propulsion methods. LÄS MER
5. Thermo-mechanical fatigue of castiron for engine applications
Master-uppsats, KTH/Maskinkonstruktion (Inst.)Sammanfattning : In an engine component the repeated start-stop cycles cause temporal and local inhomogeneous temperatures, which in turn lead to a type of low-frequency loading, plastic deformation and eventually failure due to thermo-mechanical fatigue. Simultaneously, high-frequency mechanical loading arises from the cyclic combustion pressure and from road induced vibrations. LÄS MER
