1. Investigating the influence of the tidal regime on harbour porpoise Phocoena phocoena distribution in Mount’s Bay, Cornwall
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : Investigating the influence of the tidal regime on harbour porpoise Phocoena phocoena distribution in Mount’s Bay, Cornwall Abstract Unintentional by-catch in fishing gear is a significant cause of mortality of harbour porpoises in UK waters. Understanding the spatial distribution of harbour porpoises at fine scales and how this changes over time is essential when trying to understand where these lethal interactions might occur. LÄS MER
2. The Ecological and Anthropogenic Impacts of fishing gear in a tropical system : How the size of Spotted Rose Snapper (Lutjanus guttatus) and the ratio of target catch, is influenced by approved fishing gear within a marine area of responsible fishing in the South-Western Gulf of Nicoya, Costa Rica.
Kandidat-uppsats, Linnéuniversitetet/Institutionen för biologi och miljö (BOM)Sammanfattning : The oceans are essential for humanity, yet these systems continue to be degraded and suffer from pollution, habitat destruction and overexploitation. The Costa Rican Gulf of Nicoya is a productive gulf that is fished by both large-scale industrial fisheries and small-scale artisanal fishermen. LÄS MER
3. Modeling and Control of a PMSM Operating in Low Speeds
Master-uppsats, Linköpings universitet/FordonssystemSammanfattning : A permanent magnet synchronous motor is a type of motor that is used in several different application areas, not least in an autonomous robots where it is the motor that drives the wheels. Today, many actors choose simulation as a tool to save money and time when product tests are performed. LÄS MER
4. On the friction and failure mechanisms of bearing and gear surfaces lubricated by a novel nanoadditive in highly stressed operating conditions
Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : Obtaining an enhanced lifespan for mechanical transmissions has become a challenge in diverse application sectors. Micropitting as a contact fatigue mechanism has seriously jeopardized the well-being of rolling-sliding elements present for instance in gearboxes. LÄS MER
5. Steer-by-wire system safety aspects
Master-uppsats, KTH/Väg- och spårfordon samt konceptuell fordonsdesignSammanfattning : This thesis research the system safety aspects of a Steer-by-Wire system by studying how a driver handles faults in the system. To start with, identification of risks in the SbW system was performed, followed by identification of potential faults with the help of a HAZOP study. LÄS MER
