  1. 1. Adjoint-based Formulation for Shape Optimization Problems in Computational Fluid Dynamics

    University essay from KTH/Matematik (Avd.)

    Author : Anton Scotte; [2023]
    Keywords : ;

    Abstract : A continuous adjoint formulation for exterior optimization of Dirichlet data on the boundary for potential flow applications has been developed in this thesis. This has been performed by utilizing boundary integral methods for both the primal problem (Laplace’s equation) and for the corresponding adjoint equation (Poisson’s equation) on the unit disc.

  2. 2. Private Equity Portfolio Management and Positive Alphas

    University essay from KTH/Matematisk statistik

    Author : Rikard Franksson; [2020]
    Keywords : Nordic private equity performance; private equity valuation; CAPM; portfolio optimization; multivariate linear regression; quadratic optimization; Nordiskt privatkapitals prestation; värdering av privatkapital; CAPM; portföljoptimering; multipel linjär regression; kvadratisk optimering;

    Abstract : This project aims to analyze Nordic companies active in the sector of Information and Communications Technology (ICT), and does this in two parts. Part I entails analyzing public companies to construct a valuation model aimed at predicting the enterprise value of private companies. READ MORE

  3. 3. Evaluation of Homogeneity in Drug Seizures Using Near-Infrared (NIR) Hyperspectral Imaging and Principal Component Analysis (PCA)

    University essay from Linköpings universitet/Kemi

    Author : Olle Strindlund; [2020]
    Keywords : Homogeneity; drug seizures; pharmaceuticals; NIR hyperspectral imaging; chemometrics; PCA;

    Abstract : The selection of a representative sample is a delicate problem when drug seizures comprised of large number of units arrive at the Swedish National Forensic Centre (NFC). If deviating objects in the selected sample size are found, additional analyzes are required to investigate how representative the results are for the entire population. READ MORE

  4. 4. LES Modelling of Turbulent Flow Through an Array of Cylinders Using OpenFOAM

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Hanna Isaksson; [2019]
    Keywords : Porous media; OpenFOAM; premeability; LES; packed cylinders; turbulence;

    Abstract : The objective for this master thesis project was to perform simulations for high and low Reynolds number for a porousmedia modelled as quadratic packed cylinders. The simulations were to be performed by using the open source codeOpenFOAM and the turbulence should be modelled by the LES turbulence model in order to resolve details about theturbulence.

    Author : Joar Bagge; [2015]
    Keywords : Fluid mechanics; Stokes flow; rigid body dynamics; spheroidal particles; inertia; integral equations; boundary integrals; double layer potentials; quadrature by expansion; Jeffery orbits; linear shear flow; quadratic flow; paraboloidal flow; Strömningsmekanik; Stokesflöde; stelkroppsdynamik; sfäroidiska partiklar; tröghet; integralekvationer; randintegraler; dubbellagerpotentialer; quadrature by expansion; Jeffery-banor; linjärt skjuvflöde; kvadratiskt flöde; paraboloidiskt flöde;

    Abstract : Particle suspensions occur in many situations in nature and industry. In this master’s thesis, the motion of a single rigid spheroidal particle immersed in Stokes flow is studied numerically using a boundary integral method and a new specialized quadrature method known as quadrature by expansion (QBX).
