  1. 1. Simulate Bacterial Movement through Chemotaxis

    University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

    Author : Rasmus Durgé; Johan Ek; Jonny Fredriksson; Emil Logren; Mohamad Melhem; Rik Muijs; [2021-09-14]
    Keywords : chemotaxis; computational biology; agent-based simulation; Unity engine;

    Abstract : This thesis describes the development of an agent-based simulation of E. coli chemotaxis in C# and the Unity game engine. The agents use a mathematical model of the chemical pathway underlying chemotaxis to produce either forward-motion (running) or rotation (tumbling), in response to the concentration of ligand in their immediate environment.

    Abstract : The purpose of this project was to study Svenska Aerogel AB’s product Quartzene®, and develop its capacity as a thermal insulator. Quartzene® is a silica based mesoporous material developed by Svenska Aerogel AB, with properties similar to aerogels produced by the sol-gel process. READ MORE

  6. 5. Seeking Active Returns - A Study of Restructing Strategies for Equity Index-Linked Notes

    University essay from Göteborgs universitet/Företagsekonomiska institutionen

    Author : Johan Edvardsson; Karl-Johan Ek; [2013-06-28]
    Keywords : Equity index-linked notes; restructuring; structured products; index-linked products; GARCH 1; 1 ; principal-protection; time series analysis;

    Abstract : Aim and purpose: The aim of the study is to examine whether an active strategy for restructuring of equity index-linked notes can generate higher returns than a passive ‘buy-and-hold’ strategy. More specifically, the purpose of the study is to examine how an active restructuring strategy, using specific variables to govern market timing, for equity index-linked notes may affect the returns over a given time period, compared with a passive ‘buy-and-hold’ strategy.
