  1. 1. Computational modelling in systems biology: from rewriting cell fates to detecting tumours

    Författare :Emil Andersson; Centrum för miljö- och klimatvetenskap (CEC); []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Beräkningsmodeller; Systembiologi; Genreguleringsnätverk; Cellomprogrammering; Energilandskap; iPSC; Agentbaserad modellering; T-cellsutveckling; Maskininlärning; Tumördiagnostik; Computational modelling; Systems biology; Gene regulatory network; Cell reprogramming; Energy landscape; iPSC; Agent-based modelling; Multi-scale modelling; T-cell development; Machine learning; Tumour diagnostics;

    Sammanfattning : Computational modelling is becoming an increasingly important tool in biological research. By performing computer simulations of models, it becomes possible to test theories about a biological system against experimental data. Simulations can also be used as a replacement for experiments otherwise unattainable. LÄS MER

  3. 2. Leaching of concrete : experiments and modelling

    Författare :Tomas Ekström; Avdelningen för Byggnadsmaterial; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; betongdammar; urlakning; dammar; beständighet; skador; laboratorieförsök; beräkningsmetoder; simulering; beräkningsmodeller;

    Sammanfattning : Many concrete dams, and other concrete structures within the hydropower industry are old and in a more or less severe state of degradation. Leaching is, together with freeze-thaw, the most common degradation problem in Swedish hydraulic concrete structures. LÄS MER

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

    Författare :Lars-Erik Harderup; Avdelningen för Byggnadsfysik; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  5. 4. Behaviour of fracture process zones in concrete influenced by simultaneously applied normal and shear displacements

    Författare :Manouchehr Hassanzadeh; Avdelningen för Byggnadsmaterial; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; softening; mixed mode; fictitious crack model; concrete; deformationer; betong; brottmekanik; hållfasthet; brotthållfasthet; spänningar; skjuvspänningar; sprickor; beräkningsmodeller; brottenergi; teori; laboratorieförsök; interlock; crack path; diagonal crack; microcracking; instability; fracture energy; fracture mechanics; shear; tension; process zone;

    Sammanfattning : The thesis deals with the determination of the post peak behaviour of concrete in pure tension, and combined tension (compression) and shear. A test arrangement has been developed in order to determine the post peak behaviour of concrete expressed as stress - displacement curves. LÄS MER

    Sammanfattning : The main focus in this licentiate thesis is a description of the environmentally introduced action of diffusing and chemically reactive (e.g. carbonation and chemical-physical adsorption-desorption) matter in the pore solution and in the air-filled space in the pore system of the material.
