  1. 1. Thermo-electric temperature measurements in friction stir welding Towards feedback control of temperature

    University dissertation from Trollhättan : University West

    Author : Ana Magalhães; Högskolan Väst.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; FSW; Robotic; Temperature; TWT; Plunge; Control; Production Technology; Produktionsteknik;

    Abstract : Friction Stir Welding has seen a fast uptake in many industry segments. Mechanical properties superior to fusion welding, the ability to weld "unweldable" aluminium alloys and low distortion are often described as the main reasons for the fast industrial implementation of FSW. Most existing applications consist of long straight welding joints. READ MORE

  2. 2. Compartment Fire Temperature Calculations and Measurements

    University dissertation from Luleå University of Technology

    Author : Alexandra Byström; Luleå tekniska universitet.; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; compartment fire temperature; heat transfer; FEM; calculation of temperature; temperature measurement; fire scenario; validation; flashover; Stålbyggnad; Steel Structures;

    Abstract : This thesis is devoted to heat transfer and fire dynamics in enclosures. It consists of a main part which summarizes and discusses the theory of heat transfer, conservation of energy, fire dynamics and specific fire scenarios that have been studied. READ MORE

  3. 3. Bacterial and fungal growth in soil: The effect of temperature and substrate addition

    University dissertation from Department of Biology, Lund University

    Author : Stephanie Reischke; Lunds universitet.; Lund University.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bacterial growth; Fungal growth; Respiration; Carbon loading; Glucose mineralisation; Temperature adaptation; Temperature sensitivity; Temperature dependence;

    Abstract : Bacteria and fungi are the main agents in decomposition of soil organic matter. Their activity is determined by the availability and quality of substrate, especially its content of carbon, but also nitrogen and phosphorus. Other environmental factors, which affect the activity of the microbial community in soil, are temperature, moisture and pH. READ MORE

  4. 4. Spatial variations of the urban climate and its influence on thermal comfort and behaviour

    University dissertation from Göteborg : Göteborg University

    Author : Fredrik Lindberg; Göteborgs universitet.; Gothenburg University.; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sky view factor; air temperature; surface temperature; GIS; raster modelling; mean radiant temperature; globe temperature; the SOLWIEG-model; human behaviour; outdoor activity;

    Abstract : The increased number of people living in urban areas emphasises the need for an improved understanding of how the urban climate affects human activity and behaviour. The spatial and temporal variation of climate within cities is an important factor in people’s health and well-being. READ MORE

  5. 5. Climate and dengue fever early warning based on temperature and rainfall

    University dissertation from Umeå : Umeå University

    Author : Yien Ling Hii; Umeå universitet.; [2013]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; dengue fever; temperature; rainfall; forecasting model; early warning; epidemic; dengue risk index; Public health; folkhälsa;

    Abstract : Background: Dengue is a viral infectious disease that is transmitted by mosquitoes. The disease causes a significant health burden in tropical countries, and has been a public health burden in Singapore for several decades. Severe complications such as hemorrhage can develop and lead to fatal outcomes. READ MORE
