  1. 31. Classical molecular dynamics simulations of collision-induced absorption : method development and evaluation

    Författare :Wissam Fakhardji; Magnus Gustafsson; Javier Martin-Torres; Jean-Michel Hartmann; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Applied Physics; Tillämpad fysik;

    Sammanfattning : In this thesis collision-induced absorption (CIA) coefficients are computed using molec-ular dynamics (MD) simulations. Part I is dedicated to the theoretical frame of the method, from the classical theory radiation to the derivation of an absorption coefficient. LÄS MER

  3. 32. Simulation of individual cells in flow

    Författare :Lailai Zhu; Luca Brandt; Michael Graham; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydrodynamic interaction; swimming microorganisms; capsule; Stokes flow; finite element method; boundary integral method; general geometry Ewald method; spectral element method; viscoelastic fluid; cellular deformation; flow cytometry; cell sorting; microrheology; Teknisk mekanik; Engineering Mechanics;

    Sammanfattning : In this thesis, simulations are performed to study the motion ofindividual cells in flow, focusing on the hydrodynamics of actively swimming cells likethe self-propelling microorganisms, and of passively advected objects like the red bloodcells. In particular, we develop numerical tools to address the locomotion ofmicroswimmers in viscoelastic fluids and complex geometries, as well as the motion ofdeformable capsules in micro-fluidic flows.

  4. 33. Model-Based Verification of Dynamic System Behavior against Requirements : Method, Language, and Tool

    Författare :Wladimir Schamai; Peter Fritzson; Hans Vangheluwe; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Modeling and simulation of complex systems is at the heart of any modern engineering activity. Engineers strive to predict the behavior of the system under development in order to get answers to particular questions long before physical prototypes or the actual system are built and can be tested in real life.

  5. 34. Efficiency Improvements in Waste-to-Energy Combustion Processes : Method Development and Evaluation

    Författare :Eboh Francis Chinweuba; Simon Harvey; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solid waste; exergy; entropy; higher heating value; improvement potential; waste-to-energy plant; efficiency improvement; cost evaluation; simulation; modelling; Resource Recovery; Resursåtervinning;

    Sammanfattning : is the energy recovery method. The electrical efficiency of this technology, however, is generally low when compared with other solid fuel-fired combustion plants as a result of low steam properties. Furthermore, there is lack of efficient methods to evaluate the performance of this system. LÄS MER
