  1. 16. Model Predictive Control for Ground Source Heat Pumps : Reducing cost while maintaining comfort

    University essay from Linköpings universitet/Reglerteknik

    Author : Isak Bokne; Charlie Elf; [2023]
    Keywords : MPC; Model Predictive Control; heat pump control; electricity spot price; weather prediction; reducing cost;

    Abstract : Today, the control of heat pumps aims to first and foremost maintain a comfortable indoor temperature. This is primarily done by deciding input power based on outside temperature. The cost of electricity, which can be rather volatile, is not taken into account. READ MORE

  3. 17. Joint CFR and DPD optimization for 5G Digital Front Ends

    University essay from Lunds universitet/Matematik LTH

    Author : Gustav Olsson; [2023]
    Keywords : Crest Factor Reduction; Digital Pre-Distortion; Power Amplifier; Parameter Optimization; 5G; Base Station; Memory Polynomial; Technology and Engineering;

    Abstract : This thesis project investigates the topic of joint optimization for crest factor reduction and digital predistortion blocks, which are used for digital correction of analogue impairments in digital radio front ends. The work first investigates the effects of joint parameter variation of the above blocks on the global performance and computational cost of the digital chain, given reference CFR and DPD algorithms.

  4. 18. Topic Modeling for Customer Insights : A Comparative Analysis of LDA and BERTopic in Categorizing Customer Calls

    University essay from Umeå universitet/Institutionen för matematik och matematisk statistik

    Author : Henrik Axelborn; John Berggren; [2023]
    Keywords : Customer Insights; Natural Language Processing; Topic Modeling; Latent Dirichlet Allocation; BERTopic;

    Abstract : Customer calls serve as a valuable source of feedback for financial service providers, potentially containing a wealth of unexplored insights into customer questions and concerns. However, these call data are typically unstructured and challenging to analyze effectively. READ MORE

  5. 19. Ray-tracing Based Investigations on the Deployment of RISs in Indoor Scenarios

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Swaroop Divya Sai Prem Nambala; Dexin Kong; [2023]
    Keywords : Reconfigurable intelligent surface; RIS; optimization; Ray-tracing; Mixed integer linear programming MILP ; Complex impulse response; Wireless Insite.; Technology and Engineering;

    Abstract : Reconfigurable intelligence surface (RIS) is a promising candidate technology for future 6G wireless communication systems. In existing communication systems, the network operators are unable to control the propagation environment, which causes significant limitations on communication performance. READ MORE

  6. 20. Grey-box Modeling of Hydropower Plants for Improved Frequency Regulation : Evaluation of Double-Regulated Hydropower Turbines for Fulfillment of the New FCR-requirements

    University essay from Uppsala universitet/Elektricitetslära

    Author : Karolina Engström; Rebecca Waldenfjord; [2023]
    Keywords : Double-regulated hydroturbines; Grey-box modeling; FCR-requriements; Frequency contaminent reserve; Hydropower modeling; Dynamic stability; Dynamic performance;

    Abstract : Over the last decades, the frequency on the Nordic electrical power grid has deteriorated. Therefore, new stricter requirements are developed for the hydropower delivering regulating active power on the Frequency Containment Reserve market (FCR). READ MORE
