  1. 1. Data Driven Model Identification for Remote Electrical Tilt Systems

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Raphaël Ashruf; [2023]
    Keywords : ;

    Abstract : This thesis explores the use of supervised machine learning for modelling the dynamics of Remote Electrical Tilt (RET) telecom systems. Three methodologies, including linear regressionfor linear dynamics models, Gaussian Process (GP) regression, and Recurrent Neural Networks (RNN) with Gated Recurrent Units (GRU) are proposed.

  3. 2. Fouling modelling in a UHT unit based on plant data.

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Thai Lam; [2023]
    Keywords : UHT; dairy; tubular heat exchanger; fouling development; fouling removal; food engineering; Technology and Engineering; Agriculture and Food Sciences;

    Abstract : Heat treatment of dairy products is essential for food safety, one way to perform this is ultra-high temperature (UHT) processing. During the process, macronutrients and minerals form fouling deposits which impairs heat transfer. Eventually the fouling needs to be removed chemically by alkaline and acidic detergents. READ MORE

  4. 3. Data-driven modelsfor estimating heatpump powerconsumption

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Monika Peskova; [2023]
    Keywords : heat pump; data-driven model; modelling; regression model; värmepump; data modell; modellering; regressionsmodell;

    Abstract : The number of installed heat pumps has been rapidly increasing in recent years, acceleratingthe decarbonisation of the heating sector. The impact of the increasing deployment of heatpumps on the grid can be evaluated with the help of models estimating the heat pumppower consumption. READ MORE

  5. 4. Physics-Enhanced Machine Learning for Energy Systems

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Henrik Lindström; Emil Sundström; [2022]
    Keywords : Technology and Engineering;

    Abstract : Building operations account for a large amount of energy usage and the HVAC (Heating, Ventilation and Air Conditioning) systems are the largest consumer of energy in this sector. To reduce this demand, more energy-efficient control algorithms are implemented and a popular choice for a controller is the model predictive control. READ MORE

  6. 5. Artificial Neural Network in Exhaust Temperature Modelling : Viability of ANN Usage in Gasoline Engine Modelling

    University essay from Linköpings universitet/Fordonssystem; Linköpings universitet/Tekniska fakulteten

    Author : Musa Nibras; Roos Linus; [2022]
    Keywords : Artificial Neural Network; Data-driven Modelling; Engine Modelling; Transient behaviour; Static behaviour; Feed Forward Network; Layer Recurrent Network; NARX; Long Short Term Memory; Gated Recurrent Network; Data processing;

    Abstract : Developing and improving upon a good empirical model for an engine can be time-consuming and costly. The goal of this thesis has been to evaluate data-driven modelling, specifically neural networks, to see how well it can handle training for some static models like the mass flow of air into the cylinder, mean effective pressure and pump mean effective pressure but also for transient modelling, specifically the exhaust gas temperature.
