  1. 1. Development of a cable analysis theory based on integral equation derivation

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

    Author : Sandra Larsson; [2023]
    Keywords : ;

    Abstract : Electrification of transportation is a major subject of research today, especially in air travel. The increasing number of electronics and cables also increases the interference between them. From this, interest grew to increase the accuracy of electromagnetic modeling of cables. READ MORE

  3. 2. A C++ Matrix library for computing the Gateaux derivative of the Fermi-Dirac operator

    University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

    Author : William Samuelsson; [2023]
    Keywords : C ; Quantum Chemistry; Matrix functions;

    Abstract : Computing the Fermi-Dirac operator is done through recursive polynomial expansions, using the SP2 and SP2 Acc algorithms. The Gateaux derivative is computed for both schemes by mapping the zeroth and first order matrices onto a block upper triangular matrix, which is implemented in Python using Numpy arrays to store full matrices and in C++ by first constructing a basic matrix library to use as blocks in a later created block upper triangular matrix library which only directly references two blocks in a 2 x 2 block matrix.

  4. 3. Method development of flow cytometry analysis of yeast and lactic acid bacteria viability for alcohol fermentation

    University essay from Lunds universitet/Teknisk mikrobiologi; Lunds universitet/Bioteknik

    Author : Megha Komahan; [2023]
    Keywords : Flow cytometry; yeast; lactic acid bacteria; fermentation; cell viability; applied microbiology; Technology and Engineering;

    Abstract : The usage of yeast in conventional brewing techniques involving alcoholic fermentation is an age-old process. Analyzing the viability and obtaining physiological information regarding the microbial diversity of the fermentation samples plays a pivotal role in obtaining real-time information as well as developing a more efficient process design.

  5. 4. System Identification of a Fixed-Wing UAV Using a Prediction Error Method

    University essay from Linköpings universitet/Reglerteknik

    Author : Trulsa Eriksson; [2023]
    Keywords : System identification; Fixed-wing UAV; Modelling; Parameter estimation;

    Abstract : Unmanned aerial vehicles (UAVs) is a rapidly expanding area of research due to their versatile usage, such as inspection of places inaccessible to humans and surveillance missions. This creates a demand for a reliable model that can accurately describe the dynamics of the system in order to improve the performance of the vehicle.

  6. 5. Improved Statistical Methods for Elliptic Stochastic Homogenization Problems : Application of Multi Level- and Multi Index Monte Carlo on Elliptic Stochastic Homogenization Problems

    University essay from Uppsala universitet/Tillämpad beräkningsvetenskap

    Author : Khalil Daloul; [2023]
    Keywords : Homogenization; Multilevel Monte Carlo; Multi-Index Monte Carlo; Monte Carlo; Multiscale methods;

    Abstract : In numerical multiscale methods, one relies on a coupling between macroscopic model and a microscopic model. The macroscopic model does not include the microscopic properties that the microscopic model offers and that are vital for the desired solution. READ MORE
