  2. 21. Design, Optimization and Evaluation of a Transonic Aeroelastic Rig

    Author : Simeng Tian; Andrew R. Martin; Mauricio Gutierrez Salas; Dieter Peitsch; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transonic compressor; Aeroelastic rig; Design; CFD; Unsteady flow; Energiteknik; Energy Technology;

    Abstract : The compressor is one of the most essential components of a modern turbomachinery engine. This component is exposed to vibrations that without proper design can damage structural integrity and lead to failure. READ MORE

  4. 22. Analysis of Fatigue Characteristics in Mooring Lines and Low Voltage Cables for Wave Energy Converters

    Author : Shun-Han Yang; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wave energy converter; de-coupled analysis; power cable; fatigue; dynamic cable; heaving point absorber; mooring line; coupled analysis; power absorption; marine biofouling effect on absorbed power; low voltage cable; catenary mooring chain; marine biofouling effect on fatigue;

    Abstract : To reduce both carbon emission and fossil fuel consumption, there is a pressing need for the exploitation of renewable sources of energy such as biomass, hydropower, solar power, waves, and wind. This thesis addresses the application of wave energy, which has a large potential to contribute to the world’s renewable emission-free energy supply. READ MORE

  5. 23. Seasonal flight patterns of the Spruce bark beetle (Ips typographus) in Sweden : phenology, voltinism and development

    Author : Petter Öhrn; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : The major bark beetle threat to Norway spruce (Picea abies (L.) Karst.) in Eurasia is the spruce bark beetle Ips typographus. Beetles cause damage after population build-up in defenseless trees. READ MORE

  6. 24. Pesticide use in periurban areas : farmers’ and neighbours’ perceptions and attitudes, and agricultural field influences on pests in nearby garden plants

    Author : Ahmed Nur; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Public concern about pesticide use is very high, although it varies with social, ethical and political factors. In periurban regions, farmers live close to people with other occupations. Thus farming activities such as pesticide spraying may cause tensions. READ MORE

  7. 25. Analysis of the Fatigue Characteristics of Mooring Lines and Power Cables for Floating Wave Energy Converters
