  1. 1. Molecular Insights into the Interactions of Monovalent Cations with Highly charged Fatty Acid Monolayers

    University essay from KTH/Kemi

    Author : Ran Carlhamn Rasmussen; [2023]
    Keywords : VSFS; Langmuir monolayer; ion specific effects; modified Poisson Boltzmann; carboxylic acid; VSFS; Langmuir monolager; jonspecifika effekter; modifierad Poisson Boltzmann; karboxylsyra;

    Abstract : Vibrational sum frequency spectroscopy har använts för att studera interaktionerna mellan monovalenta joner och laddade fettsyramonolager. Subfasen bestod av utvalda alkalihydroxidsaltlösningar med pH12, med huvudfokus på cesiumjonen. READ MORE

  3. 2. 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.

  4. 3. Evaluating the Effects of Neural Noise in the Multidigraph Learning Rule

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Gustav Bressler; Sigvard Dackevall; [2023]
    Keywords : ;

    Abstract : There exists a knowledge gap in the field of Computational Neuroscience, where many learning models for neural networks fail to take into account the influence of neural noise. The purpose of this thesis was to address this knowledge gap by investigating the robustness of the Multidigraph learning rule (MDGL) when exposed to two kinds of neural noise: external noise and internal noise.

  5. 4. Analyzing Survey Response Time and Response Rate for Colorectal Cancer Patients Using Logistic and Poisson Regression

    University essay from KTH/Matematisk statistik

    Author : Anna Möller; Martina Lagerros; [2023]
    Keywords : Applied Mathematics; Regression; Poisson Regression; Logistic Regression; Statistics; Cancer; Patients; Healthcare; Tillämpad Matematik; Statistik; Regression; Logistisk Regression; Poisson Regression; Cancer; Patientvård;

    Abstract : Cancer is a highly prevalent disease worldwide, claiming hundreds of lives each year. In the field of cancer research, it is customary to conduct surveys in which patients are asked to self-report and assess their symptoms and overall health. READ MORE

  6. 5. A Novel Method for Finding Overlap Depth : Development of ArtiaX, a ChimeraX plugin

    University essay from Linköpings universitet/Tillämpad matematik; Linköpings universitet/Tekniska fakulteten

    Author : Gunnar Arctaedius; [2023]
    Keywords : Cryo-electron tomography; image processing; surface visualization; overlap measurement; normal projection method; Kryoelektrontomografi; bildbehandling; ytvisualisering; överlapsmätning; normalprojektionsmetoden;

    Abstract : Visualization and image filtering are important parts of cryo-electron tomography analysis. ArtiaX, a plugin developed for UCSF ChimeraX, has been extended to improve the functionality of these two parts. For the visualization, a method of moving 3D surfaces to remove overlap between them has been developed and implemented. READ MORE
