  2. 21. From recovery boiler to integration of a textile fiber plant : Combination of mass balance analysis and chemical engineering

    Author : Hans Magnusson; Ulf Germgård; Gunnar Henriksson; Hans Theliander; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; kraft pulping; recovery boiler; smelt properties; non-process elements; oxygen delignification; viscose manufacturing; integrated production; regenerated cellulose; sulfatmassa; fysikaliska egenskaper; smälta; sodapanna; processfrämmande ämnen; bioraffinaderi; integrerad produktion; regenererad cellulosa; Chemical Engineering; Kemiteknik;

    Abstract : Modern chemical technology is an efficient tool for solving problems, particularly within the complex environment of the pulp and paper industry, and the combination of experimental studies, mill data and mass balance calculations are of fundamental importance to the development of the industry. In this study various examples are presented, whereby chemical technology is of fundamental importance. READ MORE

  4. 22. Relativenobility of precipitated phases in stainless steels : Evaluation with a combination of local probing techniques

    Author : Namurata Sathirachinda; Jinshan Pan; Thomas Ladwein; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Teknisk materialvetenskap;

    Abstract : Stainless steels often exhibit complex transformation and precipitation behaviour due to a high content of alloying elements. Secondary phases can be formed in the temperature range of 300-1000°C and are generally undesirable due to their detrimental effect on mechanical properties and corrosion resistance of stainless steels.

  5. 23. Evaluation of hand skin temperature : Infrared thermography in combination with cold stress tests

    Author : Katarina Leijon Sundqvist; Niklas Lehto; James Mercer; Luleå tekniska universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cold provocation; rewarming; thermoregulation; dynamic IR thermography; Health Science; Hälsovetenskap;

    Abstract : AbstractSince ancient times, warm or cold skin on the human body has been used as a parameter in evaluating health. Changes in body temperature are attributed to diseases or disorders. The assessment of body temperature is often performed to measure fever by detecting an elevated core temperature. READ MORE

  6. 24. Transportation Mission-Based Optimization of Heavy Combination Road Vehicles and Distributed Propulsion, Including Predictive Energy and Motion Control

    Abstract : This thesis proposes methodologies to improve heavy vehicle design by reducing the total cost of ownership and by increasing energy efficiency and safety. Environmental issues, consumers expectations and the growing demand for freight transport have created a competitive environment in providing better transportation solutions. READ MORE

  7. 25. Combination of space-geodetic techniques in the era of VGOS and multi-GNSS

    Author : Periklis Diamantidis; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Local Ties; EOP; Reference Systems; GNSS; VLBI; Combination on the Observation Level; multi-GNSS; Space Geodesy; VGOS;

    Abstract : The definition and maintenance of accurate and stable Earth-fixed and inertial reference frames is crucial in studying, among else, geophysical and geodynamical phenomena, precise positioning, and space navigation. The tools used to this end are space-geodetic techniques, like e.g. READ MORE
