  1. 1. Modeling and Control of the Paper Machine Drying Section

    University dissertation from Department of Automatic Control, Lund Institute of Technology, Lund University

    Author : Ola Slätteke; Lund University.; Lunds universitet.; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reglerteknik; robotteknik; Automatiska system; Moisture control; Paper-making; Pressure control; Predictive Control; Mid-ranging Control; Wood; Drying Section Modeling; Automation; control engineering; robotics; pulp and paper technology; Pappers- och massateknik;

    Abstract : The topic of this thesis is modeling and control of the last part of the paper machine - the drying section. Paper is dried by letting it pass through a series of steam heated cylinders and the evaporation is thus powered by the latent heat of vaporization of the steam. READ MORE

  2. 2. Automated Manufacture of Fertilizing Agglomerates from Burnt Wood Ash

    University dissertation from IEA, LTH, Box 118, SE-221 00 Lund, Sweden

    Author : Thomas Svantesson; Lund University.; Lunds universitet.; [2002]

  3. 3. On Sahelian-Sudan rainfall and its moisture sources

    University dissertation from Stockholm : Department of Meteorology, Stockholm University

    Author : Abubakr A. M. Salih; Stockholms universitet.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sudan; Sahel; rainfall; land use; deforestation; moisture sources; moisture transport; Lagrangian; moisture tagging; regional model; climate modeling; Atmospheric Sciences and Oceanography; atmosfärvetenskap och oceanografi;

    Abstract : The African Sahel is one of the most vulnerable regions to climate variability at different time scales. It is an arid to semi-arid region with limited water resources. The summer rainfall is one of these sources, but it exhibits pronounced interannual variability. This thesis presents several aspects of Sahelian Sudan rainfall. READ MORE

  4. 4. Concrete slab on the ground and moisture control : verification of some methods to improve the moisture conditions in the foundation

    University dissertation from Byggnadsfysik LTH, Lunds Tekniska Högskola

    Author : Lars-Erik Harderup; Lund University.; Lunds universitet.; [1991]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Concrete slab; moisture; repair methods; ventilated foundation; drainage; numerical methods; grunder; grundplattor; platta på mark; betongplattor; fuktskador; reparationsmetoder; dränering; ventilerade konstruktioner; fukt; fukttransport; relativ fuktighet; temperatur; luftflöden; beräkningsmodeller; teori; fältundersökningar; mätresultat;

    Abstract : This work deals with different types of repair methods for concrete slab on the ground damaged by moisture. Many of the available methods involve some kind of mechanical ventilation of the foundation. The basic principle for all these systems is the same. READ MORE

  5. 5. Active friction control by using CO2 and moisture

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Jing Hua; Luleå tekniska universitet.; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; friction control; Machine Elements; Maskinelement;

    Abstract : Nowadays the demand for intelligent control of tribological interactions is strongly increasing in various applications. We often strive to minimize friction but there are also many situations where high friction is desirable. In some cases, something in between, i.e. READ MORE
