  1. 1. Evolutionary Properties of Neural Networks: Exploration of Robustness and Evolvability in the Genotype-Phenotype Map

    Master-uppsats, Lunds universitet/Beräkningsbiologi och biologisk fysik

    Författare :Daesung Cho; [2022]
    Nyckelord :robustness; evolvability; genotype-phenotype map; canalization; Bayesian inference; simulation-based inference; information theory; neural networks; pyloric rhythm; Physics and Astronomy;

    Sammanfattning : Evolution is a fundamental and crucial part of life that hinges on two central properties: robustness and evolvability. Robustness is required to maintain essential traits despite mutations while evolvability produces novel traits that might prove beneficial in survival. LÄS MER

  2. 2. Prognostics for Condition Based Maintenance of Electrical Control Units Using On-Board Sensors and Machine Learning

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Gabriel Fredriksson; [2022]
    Nyckelord :machine learning; random forest; random survival forest; condition based maintenance; cbm; reliability; solder joint failure; thermomechanical cycling; ECU; lifetime prediction; data-driven; statistics; BGA; PCBA; field quality; maintenance; truck; bus; vehicle;

    Sammanfattning : In this thesis it has been studied how operational and workshop data can be used to improve the handling of field quality (FQ) issues for electronic units. This was done by analysing how failure rates can be predicted, how failure mechanisms can be detected and how data-based lifetime models could be developed. LÄS MER

  3. 3. How does a beef x dairy calving affect the dairy cow’s following lactation period?

    Master-uppsats, SLU/Dept. of Animal Breeding and Genetics

    Författare :Roberto Espinola Alfonso; [2022]
    Nyckelord :beef cattle; dairy cattle; crossbreeding; milk yield; fertility; survival;

    Sammanfattning : In dairy x beef breeding, much of the research has focused on the performance of the crossbred calves, yet little focus has been given to the subsequent performance of the cow itself. This study aimed to evaluate the performance of dairy cows for milk yield, fertility, and survival traits after giving birth to crossbred calves, and to compare this to the performance of dairy cows after giving birth to purebred dairy calves.

  4. 4. Simulate Bacterial Movement through Chemotaxis

    Kandidat-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

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

    Sammanfattning : 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.

  5. 5. Interactive Ecosystem Simulator

    Kandidat-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

    Författare :JOHAN ATTERFORS; CARL HOLMBERG; ALEXANDER HUANG; ROBIN KARHU; BRAGE LAE; ALEXANDER LARSSON VAHLBERG; [2021-09-07]
    Nyckelord :Ecosystem; Simulation; Unity; AI; ML; RL; ABM; GA; PCG; Welford;

    Sammanfattning : As ecosystems are complex domains, both analytical and computer-aided models can aid in gaining insights about their dynamics. One such computer-aided model is the concept of ecosystem simulation. This project aims to build an interactive and visual ecosystem simulation in the Unity game engine. LÄS MER
