  1. 16. Entrained flow black liquor gasification : detailed experiments and mathematical modelling

    Författare :Per Carlsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Sammanfattning : Black liquor, a by-product from the Kraft pulping process is a highly viscous fluid consisting of approximately 30% water, 30 % alkali salts and 40 % combustible material. The alkali salts originating from the pulp making process need to be recovered in order for the pulp mill to be economical and to satisfy environmental regulation. LÄS MER

  3. 17. Mathematical Modelling in Catalytic Automotive Pollution Control

    Författare :Lennart Andersson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; automotive pollution control; matematical modelling; monolith; selective catalytic reduction; mass transfer;

    Sammanfattning : Design and control of honeycomb monolith reactors for catalytic automotive pollution control by mathematical modelling of the reactor has been studied. One aspect of the design has been that the use of metallic monolithic catalysts for automotive emission control raises certain optimization possibilities. LÄS MER

  5. 19. Modelling crack-induced ultrasonic scattering in a thick-walled pipe

    Författare :Jacob Rubenson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Cylindrical pipes; Non-Destructive Testing; Crack; Ultrasonic waves; Hypersingular integral method;

    Sammanfattning : Ultrasonic testing is used in several industries where there are high demands on safety, e.g. nuclear power and aerospace industries. In the nuclear industry and elsewhere there are many pipes that need to be tested. LÄS MER

  7. 20. Stochastic dynamic modelling and statistical analysis of infectious disease spread and cancer treatment

    Författare :Theresa Stocks; Tom Britton; Michael Höhle; Daniela De Angelis; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematical modelling; infectious disease spread; cancer treatment; statistical inference; population dynamics; birth-death process; partially observed Markov process; Mathematical Statistics; matematisk statistik;

    Sammanfattning : Mathematical models have proven valuable for public health decision makers as they can provide insights into the understanding, control and, ultimately, the prevention of diseases. This thesis contains four manuscripts dealing with stochastic dynamic modelling and statistical analysis of infectious disease spread and optimization of cancer treatment. LÄS MER
