  1. 11. Dataset Drift in Radar Warning Receivers : Out-of-Distribution Detection for Radar Emitter Classification using an RNN-based Deep Ensemble

    University essay from Uppsala universitet/Avdelningen för systemteknik

    Author : Kevin Coleman; [2023]
    Keywords : Radar Emitter Classification; Pulse Descriptor Word; Out of Distribution Detection; Dataset Drift; Uncertainty Estimation; Deep Ensembles; Recurrent Neural Networks; LSTM;

    Abstract : Changes to the signal environment of a radar warning receiver (RWR) over time through dataset drift can negatively affect a machine learning (ML) model, deployed for radar emitter classification (REC). The training data comes from a simulator at Saab AB, in the form of pulsed radar in a time-series. READ MORE

  3. 12. Software Defined VNA : Measure Coupling Between Elements in an Antenna Array

    University essay from Uppsala universitet/Signaler och system

    Author : Alexander Söderlund; [2023]
    Keywords : VNA; Vector Network Analyser; SDR; KrakenSDR; S-parameter; Antenna Coupling;

    Abstract : With improvements in hardware of antenna receivers, fully digital arrays have been made possible to use in real time systems. These systems have a greater complexity, with the advantage of more dynamic system design since the use of the communication system can be changed with only a software change. READ MORE

  4. 13. Vehicle to Home and Vehicle to Grid : a study and modeling of the technical system when charging and discharging electric vehicles for households with PV systems

    University essay from Uppsala universitet/Elektricitetslära

    Author : Christine Timm; [2023]
    Keywords : electric vehilce; EV; bidirectional charging; smart charging; smart charging algorithms; optimization; PV;

    Abstract : As the world undertakes global climate goals to lower the emissions of greenhouse gases, more renewable energy sources are introduced in the electrical energy system, and fossil fuel driven combustion engines aims to be replaced by electric vehicles. New problems connected to the transition such as voltage fluctuations, production and consumption mismatch and high peak loads, requires new solutions. READ MORE

  5. 14. Research and Analysis of Suspension Dynamics of an Autonomous Bidirectional Road Vehicle

    University essay from KTH/Väg- och spårfordon samt konceptuell fordonsdesign

    Author : Isabelle Gürsac; Tsimafei Klimantovich; [2023]
    Keywords : Bidirectional vehicle; 4WS; 4WD; suspension angles; kingpin inclination; camber angle; caster angle; toe angle; relative importance; suspension setup; suspension system; drivetrain; efficiency.; Dubbelriktat fordon; fyrhjulsstyrning; fyrhjulsdrift; hjulvinklar; Kingpin-lutningsvinkel; cambervinkel; castervinkel; toevinkel; relativ betydelse; fjädringsinställning; hjulupphängningssystem; drivlina; effektivitet.;

    Abstract : The bidirectionality of road vehicles is a novel research area, which is directly connected with autonomy, efficiency, flexibility and sustainability of transportation. The research in this area is mostly performed with stringent restrictions in corporate secrecy. This fact makes the area publicly unexplored, moreover highly future oriented. READ MORE

  6. 15. Classifying personal data on contextual information

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Carl Dath; [2023]
    Keywords : Natural Language Processing; Machine Learning; Word2Vec; GloVe; BERT; Personal Data classification; Språkteknologi; Maskininlärning; Personlig Data Klassificering;

    Abstract : In this thesis, a novel approach to classifying personal data is tested. Previous personal data classification models read the personal data before classifying it. However, this thesis instead investigates an approach to classify personal data by looking at contextual information frequently available in data sets. READ MORE
