  1. 11. Climate Related Thermal Actions for Reliable Design of Concrete Structures

    Author : Oskar Larsson; Avdelningen för Konstruktionsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal stress; solar radiation; FE-analysis; climate data; box-girder bridge; KstrConcrete; KstrReliability;

    Abstract : When the temperature changes in the environment the temperature will also change in a structure. Complex interactions of climate factors affect the temperature changes. When the temperature is varied in a material it will expand or contract, and movements will be produced. READ MORE

  2. 12. Comfort climate evaluation with thermal manikin methods and computer simulation models

    Author : Håkan O. Nilsson; Högskolan i Gävle; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; equivalent temperature; subject; thermal manikin; mannequin; thermal climate assessment; heat loss; office environment; cabin climate; ventilated seat; computer model; CFD; clothing-independent; comfort zone diagram; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur;

    Abstract : Increasing concern about energy consumption and the simultaneous need for an acceptable thermal environment makes it necessary to estimate in advance what effect different thermal factors will have on the occupants. Temperature measurements alone do not account for all climate effects on the human body and especially not for local effects of convection and radiation. READ MORE

  3. 13. Design, Fabrication and Optimization of Thermal Radiation Detectors Based on Thin Polymer Membranes

    Author : Claes Mattsson; Hans-Erik Nilsson; Göran Thungström; Ylva Bäcklund; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal detector; Polymer; Membrane; SU-8; Electronics; Elektronik;

    Abstract : The number of applications in which infrared radiation sensors are used is increasing. In some applications, the cost of the sensor itself is an issue, and simple solutions are thus required. In this thesis, the investigations have related to the use of thin polymer membranes in thermal infrared sensors, such as bolometers and thermopiles. READ MORE

  4. 14. Microclimate and Thermal Comfort of Urban Spaces in Hot Dry Damascus- Influence of urban design and planning regulations

    Author : Moohammed Wasim Yahia; Boende och bostadsutveckling; []
    Keywords : HUMANIORA; HUMANITIES; Architecture; Arid zones; Damascus; Hot dry regions; Thermal indices; Urban climate; Built environment; Microclimate; Urban design; Climate; Climatic design; Planning regulations; Thermal comfort; Urban planning;

    Abstract : The aim of this study is to develop better understanding of the relationship between microclimate and urban design in the hot dry city of Damascus. This is done by studying the impact of urban regulations on microclimate in different urban design patterns in modern Damascus. READ MORE
