1. Preliminary Design and Conceptual Analysis of an Electrically Actuated Pintle Injector
Master-uppsats, Luleå tekniska universitet/RymdteknikSammanfattning : ”The Eagle has landed”. With this words, astronaut Neil Armstrong, together with astronaut Edwin ”Buzz” Aldrin, confirmed the safe landing on the Moon of the Apollo11 on July 20th, 1969. This achievement would have never been possible without the engineering behind the construction of the Moon lander. LÄS MER
2. Rotorsaksanalys av avvikande ventiler : En fallstudie hos Nordhydraulic AB
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälleSammanfattning : Mobila hydrauliska ventiler används ofta i tunga industrier för att styra hydrauliska system för att hantera material. Funktionaliteten är kritisk i dessa situationer då det utgör en miljöfara och säkerhetsfara om funktionaliteten inte är uppnådd. LÄS MER
3. Construction and Control of a 3-axisAutomated Liquid Sampling UnitUtilizing Hybrid Stepper Motors
Master-uppsats, KTH/Mekatronik och inbyggda styrsystemSammanfattning : High accuracy autonomous positioning systems are becoming increasingly important in today’s chemical industry because they can obtain precise experiment results automatically and hence allow lab technicians to focus on other tasks concurrently. One time consuming process is the process of sampling chemical test results into the correct container, especially when the tests are many and infrequent. LÄS MER
4. Development of Elastic Mechanism for actuation of Valve
Master-uppsats, KTH/MaskinkonstruktionSammanfattning : The HGR valve, or hot gas recirculation valve, is an essential component of modern internal combustion engines. Its main function is to reduce emissions of nitrous oxide (NOx), which is a harmful pollutant produced during combustion. LÄS MER
5. Design of a Bistable Origami Stent with Pneumatic Actuation
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknikSammanfattning : What if stents could be easier removed when complications arise or removed once theirjob has been done? No matter how perfect a stent design becomes, the fundamental issueis that a foreign object in the body under extended periods eventually will cause devicedegradation and complications. So instead of making a long-term solution of a perfectstent, the focus in this paper is redirected from expensive materials to a simple design,with simple materials. LÄS MER
