  1. 21. Millimetre wave waveguide enclosed grid frequency multipliers and imaging

    Author : Robin Dahlbäck; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Millimeter wave; THz imaging; THz sources; Grid; Heterostructure Barrier Var- actors HBVs ; Varactors; Array; FMCW; 2D-grid; Quasi-optical.; Frequency multipliers; Radars; sub-millimetre waves; Schottky diodes;

    Abstract : The utilisation of the THz spectrum ( 0.3-10 THz ) is hampered by fundamental difficulties in generating power at these frequencies. READ MORE

  2. 22. Test Design for Finite Element Model Updating - Identifiable Parameters and Informative Test Data

    Author : Andreas Linderholt; Thomas Abrahamsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modal tests; test design; identifiability; Fisher information; optimization; data informativeness; model updating; Maskinteknik;

    Abstract : It is important to predict structural phenomena, such as noise and fatigue, stemming from vibrations. To do this, reliable structural dynamic models are needed. To be useful the models have to compare well with reality in the validation against test data; if not, the models should be modified. READ MORE

  3. 23. Employment Status and Inequalities in Health Outcomes : Population-based Studies from Gävleborg County

    Author : Anne-Sofie Hiswåls; Gloria Macassa; Joaquim Soares; Gebrenegus Ghilagaber; Peter Öberg; Örjan Sundin; Charli Eriksson; Mittuniversitetet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Employment status; self-reported health; health inequalities; suicidal ideation; anxiety; depression; out of work; perceived well-being; qualitative approach; recession time; Gävle; Anställningsstatus; självrapporterad hälsa; ojämlikhet i hälsa; självmordstankar; ångest; depression; utanför arbetsmarknaden; upplevt välbefinnande; kvalitativt tillvägagångssätt; lågkonjunktur; Gävle;

    Abstract : Background and objectives: From a public health perspective, it is important not only to improve and maintain health, but also to promote equality in health. Epidemiological research has showed the importance of work and unemployment in the development of socio-economic health inequalities, and peoples life chances are suggested to be conditioned by participation or exclusion from the labour market.

  4. 24. Underwater radiated noise from Point Absorbing Wave Energy Converters : Noise Characteristics and Possible Environmental Effects

    Author : Kalle Haikonen; Jan Sundberg; Sigray Peter; Uppsala universitet; []
    Keywords : Wave energy conversion; renewable energy; environmental impact; marine ecology; underwater noise;

    Abstract : The conversion of wave energy into electrical energy has the potential to become a clean and sustainable form of renewable energy conversion. However, like all forms of energy conversion it will inevitably have an impact on the marine environment, although not in the form of emissions of hazardous substances (gases, oils or chemicals associated with anticorrosion).

  5. 25. Environmental Assessment and Strategic Technology Choice : The Case of Renewable Transport Fuels

    Author : Karl Hillman; Björn Sandén; Ken Green; Göteborg Chalmers Tekniska Högskola Miljösystemanalys Institutionen för energi och miljö; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; environmental assessment; life cycle assessment LCA ; socio-technical change; strategic technology choice; renewable fuels;

    Abstract : The scale of the required changes is huge, and time is limited if we are to avoid the most severe effects of climate change. To reduce greenhouse gas emissions from road transport, several fuels and electricity originating from renewable energy sources have been proposed, all of them in different stages of development and with various and shifting environmental impacts.
