  1. 21. Clothing Evaporative Resistance: Its Measurements and Application in Prediction of Heat Strain

    University dissertation from Lund University (Media-Tryck)

    Author : Faming Wang; Lunds universitet.; Lund University.; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal manikin; clothing ensemble; evaporative resistance; localised evaporative resistance; thermophysiological response; heat stress; heat strain; the Predicted Heat Strain PHS model;

    Abstract : Popular Abstract in English Clothing plays an important role in our lives. It serves four main functions: adornment, status, modesty and protection. Wearing popular clothing with one’s favourite decorations, contributes to a person reaching his or her mental comfort. Clothing is also a symbol of status, and was particularly so in ancient times.

  2. 22. Thermal detector with integrated absorber structure for mid-IR gas detection

    University dissertation from Sundsvall : Mid Sweden University

    Author : Shakeel Ashraf; Mittuniversitetet.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal detectors; Thermopile detectors; Infrared absorbers; SU-8 epoxy; Interferometric and Multi-layered absorber; Seebeck coefficient; Molybdenum di-sulfide;

    Abstract : Measurement of the concentration of greenhouse gases, such as carbon dioxide(CO 2 ) and methane (CH 4 ), in the atmosphere has received significant attention in the last few decades. This work focusses on the development of high-performance thermopile detectors for use with the non-dispersive infrared (NDIR) measurements of such gases. READ MORE

  3. 23. Active heat capacity : models and parameters for the thermal performance of buildings

    University dissertation from Byggnadsfysik LTH, Lunds Tekniska Högskola

    Author : Gudni Jóhannesson; [1981]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Time domain solutions; RC-models; Admittance; Frequency response; Simplified models; Non-steady state; Building heat transfer; värmeflöden; transienta förlopp; byggnader; beräkningsmodeller;

    Abstract : The thesis concerns the characterization and evaluation of nonsteady heat transfer in building components and building enclosures. The major aim of the underlaying research has been to assemble and develop simplified calculation procedures for this purpose. READ MORE

  4. 24. Design, Fabrication and Optimization of Thermal Radiation Detectors Based on Thin Polymer Membranes

    University dissertation from Sundsvall : Kopieringen Mittuniversitetet

    Author : Claes Mattsson; Mittuniversitetet.; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal detector; Polymer; Membrane; SU-8; TECHNOLOGY Electrical engineering; electronics and photonics Electronics; TEKNIKVETENSKAP Elektroteknik; elektronik och fotonik 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

  5. 25. On the impact of temperature perturbations on the creep of sensitive clay

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Yanling Li; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; thermal cycles; sensitive clays; oedometer tests; temperature; natural bonding; apparent preconsolidation pressure; multi-physics modelling; geothermal; static thermal loading;

    Abstract : Temperature affects the soil response, but is not fully understood and quantified and thus often ignored. The temperature fluctuations resulting from energy foundations and construction activities, such as excavations and soil stabilization, however, may lead to changes in the hydromechanical response of the clay.
