  1. 1. Patterning of the neural tube: A 3D computational modelling approach

    Master-uppsats, Lunds universitet/Institutionen för astronomi och teoretisk fysik; Lunds universitet/Beräkningsbiologi och biologisk fysik

    Författare :Ariane Ernst; [2019]
    Nyckelord :gene regulatory networks; neural tube patterning; patterning of the neural tube; dopaminergic neurons; parkinson s disease; computational modelling; stem cell; GRN; Biology and Life Sciences; Physics and Astronomy;

    Sammanfattning : Neurodegenerative diseases such as Parkinson’s can be treated with stem-cell derived specialized neurons. In order to achieve precise directed neural differentiation in vitro we need to understand the gene regulatory mechanisms behind in vivo neural tube patterning. LÄS MER

  2. 2. Estimation of fatigue life by using a cyclic plasticity model and multiaxial notch correction

    Master-uppsats, Linköpings universitet/Mekanik och hållfasthetslära

    Författare :Nils Johansson; [2019]
    Nyckelord :Multiaxial load; fatigue; notch; elastic-plastic; stress-strain; non-proportional load; incremental Neuber; damage parameter;

    Sammanfattning : Mechanical components often possess notches. These notches give rise to stress concentrations, which in turn increases the likelihood that the material will undergo yielding. The finite element method (FEM) can be used to calculate transient stress and strain to be used in fatigue analyses. LÄS MER

  3. 3. Traffic Model for Cellular Network Analysis

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Mohanad Amer; Shishira Puttaswamy; [2019]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The development of new wireless cellular network technologies is always in progress. As 3G has been considered the foundation of mobile broadband, the latest generation of cellular mobile communications, that is, 5G New Radio, is expected to realize the networked society, where everyone and everything are seamlessly connected everywhere and every time.

  4. 4. Modelling and Measurement of Industrial Manipulators for High-Precision Contact Applications

    Master-uppsats, KTH/Mekatronik

    Författare :Arian Hosseini; [2019]
    Nyckelord :;

    Sammanfattning : This study was conducted with the objective of predicting the accuracy of robotic manipulator models in contact applications. A number of computational robot models, including lumped-parameters models and flexible-body elastic models were used and refined to evaluate the behavior of a manipulator under static, quasi-static and dynamic loading conditions.

  5. 5. A COMPARISON OF THE OBSERVED WAKE EFFECT WITH SEVERAL WAKE MODELS USING BOTH ANALYTIC AND CFD SIMULATION METHODS - FOR THE CASE OF BLOCK ISLAND OFFSHORE WIND FARM

    Magister-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Robbie Pratt; [2019]
    Nyckelord :Block Island Wind Farm; Offshore Wind Power; Wake Effect; Wake Modelling; WindPRO; WindSIM; Openwind; CFD modelling.;

    Sammanfattning : This paper sets out to analyze the observed wake effect at Block Island Wind Farm. A comparison is made between several wake simulation methods and the observed data at Block Island using analytic and CFD (Computational Fluid Dynamics) modelling methods. LÄS MER
