  1. 21. Prediction of battery lifetime using early cycle data : A data driven approach

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

    Author : Isabelle Enholm; Olivia Valfridsson; [2022]
    Keywords : early prediction; Support Vector Regression; Elastic Net; battery lifetime; cycle life; battery degradation;

    Abstract : A form of laboratory tests are performed to determine battery degradation due to charging and discharging of batteries (cycling). This is done as part of quality assurance in battery production since a certain amount of degradation corresponds to the end of the battery lifetime. Currently, this requires a significant amount of cycling. READ MORE

  3. 22. Investigation of the wing design and endurance of an ultralight electrical aircraft

    University essay from Lunds universitet/Innovation

    Author : Vanda Ericson; Jonathan Palmgren; [2022]
    Keywords : Aerodynamics; Electrical Aviation; CFD; Endurance; Drag; Technology and Engineering;

    Abstract : The goal of this thesis was to explore the conversion of a propeller driven two-seater combustion airplane to an electrical airplane. Four different wing designs were considered. Two variations of Blackwing Sweden AB’s current Blackwing wing (BW), a longer wing (BW-L) and a shorter wing (BW-S), as well as a new wing with a different airfoil (GW). READ MORE

  4. 23. Data-driven forecasting of electric vehicle charging for frequency regulation

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Fredrik Sidh; Gustaf Sundell; [2022]
    Keywords : Technology and Engineering;

    Abstract : Electric vehicle (EV) charging may be used in aggregation as virtual batteries to provide a frequency regulating service to the power grid. The service is sold on the Frequency Containment Reserve (FCR) markets, and is traded one and two days ahead. Forecasts of charging patterns are essential to reliably provide this ancillary service.

  5. 24. A Study on Data-driven Methods for Selection and Evaluation of Beam Subsets in 5G NR

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

    Author : Nic Ekman; Ilias Theodoros Skordas; [2022]
    Keywords : 5G; NR; telecom; telecommunications; ML; machine learning; algorithms; beam; widebeam; propagation; beamforming; subset; RAN; radio; radio environment; ericsson; Technology and Engineering;

    Abstract : 5G New Radio is the next generation of mobile networks and it comes with promises of ultra-high speeds, ultra-high reliability and ultra-low latency. This has posed a challenge for the engineers entrusted with the task of finding solutions which could fulfil the specification, and as a result, some promising areas have received increased attention in recent years.

  6. 25. Simulations of current transport phenomena in ferroelectric tunnel junctions

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

    Author : Ivan Lubar; [2022]
    Keywords : Technology and Engineering;

    Abstract : Ferroelectric memories pose as a potential candidate as resistive memory devices that could be used for in-memory computing and artificial synapses. One promising type of ferroelectric memory device is the ferroelectric tunnel junction (FTJ). READ MORE
