1. The design of a hydraulic equalizer bar for the feeding mechanism on forest harvester heads
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : Due to the importance of a correct tree placement and the wear that occurs to equalizer bars inharvester heads, Komatsu Forest AB in Umeå was interested if the bar could be replaced with ahydraulic system. According to Komatsu, the problems were that the equalizer bars that are responsible forsynchronizing the delimbing knives and feeding mechanism add weight, take up space and have atendency to break before their life expectancy.

2. Jet Grout Bottom Plug in Deep Excavations : Numerical Analysis of a Tunnel Project
Master-uppsats, KTH/Jord- och bergmekanikSammanfattning : This master thesis has investigated the performance of a deep excavation with a jet grout bottom plug used to prevent bottom heave and hydraulic uplift failure. The concept of a jet grout plug as a structural and sealing component in a specific case was studied, namely one of the tunnel sections of The West Link tunnel project in Gothenburg. LÄS MER
3. Co-Simulation Development for Improved Cavitation Predictions in Oil-Hydraulics Systems : An investigation into the cavitating flow behavior of repetitive water hammers.
Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningsläraSammanfattning : Numerical modeling of cavitation using computational software is a highly pursued topic of research due to its impact in different industrial sectors. While some industrial applications such as wastewater treatment and mineral processing are known to advantageously use this phenomena, it remains an unwanted process in others where it is known to induce vibration, reduce performance and cause structural damage.

4. Efficiency Analysis of a Wave Energy Converter Penstock
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Novige develops a wave energy converter (WEC) concept that utilizes wind-generated wave to create electricity. The system uses a float and a hydraulic cylinder to pump water up to a turbine, similar to an inverted hydro power plant. LÄS MER
5. Automatisk justeringsmekanism för borrvinkeln på en stigortsborrmaskin
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : I dagens gruvindustri används stigortsborrmaskinen för mekanisk bergsavverkning. Stigortsborrmaskinens främsta uppgift är att borra vertikala hål från markplan eller en gruvort, ned till en underliggande gruvort. LÄS MER
