  1. 1. Image-based quantitative infrared analysis and microparticle characterisation for pulp and paper applications

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Kari Hyll; KTH.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metrology; stock; papermaking; refining; fibrillation; fines; filler; morphology; classification; flow microscopy; fibre analyser; flow cytometry; laser diffraction; dynamic image analysis; process variation; thermography; emittance; emissivity; infrared; MWIR; LWIR; goniometer; Production Engineering; Industriell produktion; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : Measurements of process variations and particle morphology are widely employed in the pulp and paper industry. Two techniques with high potential, infrared thermography and microparticle characterisation, are mainly used qualitatively. READ MORE

  2. 2. Studies of Tropospheric and Stratospheric Aerosol using Ion Beam Analysis

    University dissertation from Div. of Nuclear Physics, Dept. of Physics, Lund Institute of Technology, Lund University, P.O. Box 118, SE-221 00 Lund, Sweden

    Author : Giorgos Papaspiropoulos; Lunds universitet.; Lund University.; [2001]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; atmosphere; Aerosols; troposphere; stratosphere; ion beam analysis; PIXE; impactors; particulate sulphur; chemical speciation; elemental analysis; thermography; Physics; Nuclear physics; Fysik; Metrology; Kärnfysik; physical instrumentation; Metrologi; fysisk instrumentering; Fysicumarkivet A:2001:Papaspiropoulos;

    Abstract : Popular Abstract in Swedish Aerosolpartiklar i atmosfären har på senare år fått allt större betydelse i debatten om det globala klimatet och dess förändringar. Medan ökningen av växthusgaser bidrar till att medeltemperaturen på jorden ökar, är teorierna de motsatta vad gäller aerosolpartiklarna. READ MORE

  3. 3. Through air drying The influence of formation and pulp type on non-uniform drying and air flow

    University dissertation from Karlstad : Karlstads universitet

    Author : Aron Tysén; Karlstads universitet.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drying; Dewatering; Water removal; Moisture; Non-uniformity; Variability; Tissue; TAD; Through air drying; Thermography; Formation; Pulp; Chemical Engineering; Kemiteknik;

    Abstract : The removal of water is an integral part of tissue paper production. Through air drying (TAD) is used for water removal when producing premium tissue grade products, however, at the price of higher energy demand. A better understanding of TAD may therefore lower the energy demand. READ MORE

  4. 4. Accelerator-Based Chemical and Elemental Analysis of Atmospheric Aerosols

    University dissertation from Division of Nuclear Physics, P. O. Box 118, SE-221 00 Lund, Sweden

    Author : Besim Mentes; [1999]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; elemental analysis; chemical speciation; ammonium bisulphate; ammonium sulphate; sulphuric acid; ammonium chloride; Fysicumarkivet A:1999:Mentes; ammonium nitrate; sodium sulphate; volatile carbon; non-volatile carbon; Kärnfysik Fysicumarkivet A:1999:Mentes; Nuclear physics; Ion beam analysis IBA ; thermography; atmosphere; aerosols;

    Abstract : Aerosol particles have always been present in the atmosphere, arising from natural sources. But it was not until recently when emissions from anthropogenic (man made) sources began to dominate, that atmospheric aerosols came into focus and the aerosol science in the environmental perspective started to grow.

  5. 5. On reliability and maintenance modelling of ageing equipment in electric power systems

    University dissertation from Stockholm : KTH

    Author : Tommie Lindquist; KTH.; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reliability; maintenance; electric power systems; circuit breaker; disconnector; thermography; TECHNOLOGY Electrical engineering; electronics and photonics Electric power engineering; TEKNIKVETENSKAP Elektroteknik; elektronik och fotonik Elkraftteknik;

    Abstract : Maintenance optimisation is essential to achieve cost-efficiency, availability and reliability of supply in electric power systems. The process of maintenance optimisation requires information about the costs of preventive and corrective maintenance, as well as the costs of failures borne by both electricity suppliers and customers.
