  1. 1. PID tuning with Ant Colony Optimization (ACO) : A framework for a step response based tuning algorithm

    University essay from Mittuniversitetet/Avdelningen för elektronikkonstruktion

    Author : Carl Johan Björk; [2018]
    Keywords : PID; self-tuning; control system; building automation; ant colony optimization; neural networks; open-loop; closed-loop; step response.; PID; självtrimning; reglersystem; byggnadsautomation; myrkolonioptimering; neurala nätverk; öppen slinga; sluten slinga; stegsvar.;

    Abstract : The building automation industry lacks an affordable, simple, solution for autonomous PID controller tuning when overhead variables fluctuate. In this project, requested by Jitea AB, a solution was developed, utilising step response process modelling, numerical integration of first order differential equations, and Ant Colony Optimization (ACO).

  3. 2. Fluctuations in the CMB through inflation

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Kevin Björk; [2017]
    Keywords : ;

    Abstract : The goal of this project is to gain a better understanding of the temperature fluctuations observed in the CMB. This goal is reached with the aid of a literature study. READ MORE

  4. 3. A Novel Transfer Function for Continuous Interpolation between Summation and Multiplication in Neural Networks

    University essay from KTH/Skolan för datavetenskap och kommunikation (CSC)

    Author : Wiebke Koepp; [2016]
    Keywords : Machine Learning; Neural Networks; Transfer Functions;

    Abstract : In this work, we present the implementation and evaluation of a novel parameterizable transfer function for use in artificial neural networks. It allows the continuous change between summation and multiplication for the operation performed by a neuron. READ MORE

  5. 4. Non-contact High Voltage Measurements: Modeling and On-site Evaluation

    University essay from Institutionen för fysik

    Author : Joacim Törnqvist; [2012]
    Keywords : Capacitive; Measurement technique; Modeling; Optimization; Non-contact; Voltage measurement; Low cost; transient detection; Kapacitiv; Mätteknik; Modellering; Optimering; Beröringsfri; Spänningsmätning; Låg kostnad; Transientövervakning;

    Abstract : In the high voltage grid, voltage measurements are made in dedicated voltage-transformers. These devices are expensive and insulation failures could impact directly on the system, and even cause a power outage. READ MORE

  6. 5. Fatigue life of butt welds - a numerical study on the influence of real geometry

    University essay from KTH/Hållfasthetslära

    Author : Karthickeyan Arasu; []
    Keywords : Real weld geometry; fatigue life; edge offset; weld toe radius; crack propagation; transfer function; Monte Carlo simulation; Verklig svetsgeometri; utmattningslivslängd; kantförskjutning; svetsradie; sprickutbredning; överföringsfunktion; Monte Carlo simulering;

    Abstract : Welds play a crucial role in the product portfolio of GKN Aerospace. For ease of manufacturing and repairability, butt welds are preferred in the aerospace industry. Weld regions undergo local distortions during manufacturing due to the external heat-input, and the resulting local geometries are complex and stochastic in nature. READ MORE
