    Sammanfattning : Grey-box models are constructed by combining model components that are derived from first principles with components that are identified empirically from data. In this thesis a grey-box modelling method for describing distributed parameter systems is presented. LÄS MER

  3. 2. An Adaptive Surface Finite Element Method for the Laplace-Beltrami Equation

    Master-uppsats, KTH/Numerisk analys, NA

    Författare :Gökce Tuba Masur; [2017]
    Nyckelord :;

    Sammanfattning : In this thesis, we present an adaptive surface finite element method for the Laplace-Beltrami equation. The equation is known as the manifold equivalent of the Laplace equation. LÄS MER

  4. 3. Development of a pipeline for patientspecific finite element modelling of the left ventricle of the human heart

    Master-uppsats, KTH/Numerisk analys, NA

    Författare :Mbah Chrameh Fru; [2014]
    Nyckelord :;

    Sammanfattning : In order to perform simulations of the human heart using a heart finite element solver developed at the Computational Technology Laboratory at KTH with a data set provided by Philips consisting of surface meshes of a whole heart, the surface mesh has to be converted to a volume mesh. The conversion is manual and time consuming. LÄS MER

  5. 4. Parameter optimization of linear ordinary differential equations with application in gene regulatory network inference problems

    Master-uppsats, KTH/Numerisk analys, NA

    Författare :Yue Deng; [2014]
    Nyckelord :Ordinary differential equations; parameter optimization; gene regulatory network inference; DREAM4 project;

    Sammanfattning : In this thesis we analyze parameter optimization problems governed by linear ordinary differential equations (ODEs) and develop computationally efficient numerical methods for their solution. In addition, a series of noise-robust finite difference formulas are given for the estimation of the derivatives in the ODEs. LÄS MER

  7. 5. FE analysis of interlocking C3C solid concrete blocks without casting

    Magister-uppsats, Institutionen för teknik, TEK

    Författare :Emina Deumic; Damir Sadic; [2011]
    Nyckelord :Concrete blocks; Retaining wall; Temporary construction; Overturning; Finite Element Model; Betongblock; Stödmur; Tillfälliga konstruktioner; Vältning; Finita Element Modell;

    Sammanfattning : Solid concrete Lego blocks can be used as temporary retaining wall systems or as wall separators between different materials such as sand, salt, compost, etc. The advantage of concrete blocks is that you can create temporary constructions. It is easy to move or expand the constructions when no casting is required between the blocks.
