1. 1. Identifying Graph Characteristics in Growing Vascular Networks

   Master-uppsats, Uppsala universitet/Tillämpad beräkningsvetenskap

   Författare :Christopher Finn Plummer; [2024]
   Nyckelord :Anigogenesis; Vascular Networks; Network Science;

   Sammanfattning : One of the ways that a vascular network grows is through the process of angiogenesis, wherebya new blood vessel forms as a branch from an existing vessel towards an area which isstimulating vascular growth. Due to the demands for nutrients and waste transport, growingtumour cells will access the surrounding vascular network by inducing angiogenesis. LÄS MER

3. 2. Solving the incompressible Navier-Stokes equations in 3-D to model gas flow in a room

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för beräkningsvetenskap

   Författare :Fredrik Malmström; [2024]
   Nyckelord :;

   Sammanfattning : The thesis proposes to model the flow of gases in a room by solving the incompressible Navier-Stokes equations in three dimensions. The transportationof scalars such as temperature and concentration of CO2 is modeled by solving the advection-diffusion equation, and the effects of temperature on thevelocity is accounted for by employing the Boussinesq approximation.

4. 3. Resource Usage Prediction for Parameter Sweeps with Biochemical System Simulations

   Master-uppsats, Uppsala universitet/Tillämpad beräkningsvetenskap

   Författare :Minjia Zhou; [2024]
   Nyckelord :;

   Sammanfattning : Exploring the behavior of biochemical systems when subjected to certain internal and external changes is fascinating, and these variations can be investigated through computational simulations. However, the computational cost of simulations is often quite high, necessitating an understanding of the computational requirements and resource utilization of these simulations. LÄS MER

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

   Kandidat-uppsats, Uppsala universitet/Avdelningen för beräkningsvetenskap

   Författare :William Samuelsson; [2023]
   Nyckelord :C ; Quantum Chemistry; Matrix functions;

   Sammanfattning : 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.

7. 5. Restaurant Daily Revenue Prediction : Utilizing Synthetic Time Series Data for Improved Model Performance

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för beräkningsvetenskap

   Författare :Stella Jarlöv; Anton Svensson Dahl; [2023]
   Nyckelord :demand forecasting; data augmentation; time series data; machine learning; restaurant industry; generative adversarial networks; TimeGAN; XGBoost;

   Sammanfattning : This study aims to enhance the accuracy of a demand forecasting model, XGBoost, by incorporating synthetic multivariate restaurant time series data during the training process. The research addresses the limited availability of training data by generating synthetic data using TimeGAN, a generative adversarial deep neural network tailored for time series data. LÄS MER
