  1. 1. Implementation of Flight Mechanical Evaluation Criteria in an Aircraft Conceptual Design Tool with focus on Longitudinal Motions

    University essay from Linköpings universitet/Fluida och mekatroniska system

    Author : Argyro Giota; Aleksandra Roszkowska; [2023]
    Keywords : flight mechanics; Pacelab APD 8.1; aerodynamic derivatives; equations of motion; B747; stability and control; longitudinal dynamics; phugoid mode; short period mode; DATCOM ; OpenVSP;

    Abstract : This report focuses on the utilisation of flight mechanics in the context of aircraftconceptual design to assess stability, control, and motion characteristics. The pri-mary objective is to acquire the equations of motion and implement longitudinalstability and control criteria using Pacelab Aircraft Preliminary Design 8. READ MORE

  3. 2. 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

  4. 3. Navigability of a Web Application : How different factors alter the perceived navigability of a web application focused on letting users rent out private belongings

    University essay from Linköpings universitet/Institutionen för datavetenskap

    Author : Tobias Johansson; Axel Eklund; Axel Schmid; Kajsa Gudmundson; Louise Andersson; Martin Sörme; Oscar Lundström; Victor Olofsson Bargues; [2023]
    Keywords : navigability; web application; e-commerce; navigerbarhet; webbapplikation; e-handel;

    Abstract : The primary aim of this study was to examine the effects of a web application’s navigability on user satisfaction. This was studied by developing a web application for the rental of pri- vate belongings such as tools, party equipment, outfits, et cetera. The study’s scope was hav- ing students at Linköping University as the target group. READ MORE

  5. 4. Federated Learning for edge computing : Real-Time Object Detection

    University essay from Högskolan i Skövde/Institutionen för informationsteknologi

    Author : Ardit Memia; [2023]
    Keywords : Federated Learning; Artificial Intelligence; Machine Learning; Edge computing; Object Detection; Decentralized AI;

    Abstract : In domains where data is sensitive or private, there is a great value in methods that can learn in a distributed manner without the data ever leaving the local devices. Federated Learning (FL) has recently emerged as a promising solution to collaborative machine learning challenges while maintaining data privacy. READ MORE

  6. 5. Waveform agility for robust radar detection and jamming mitigation

    University essay from Uppsala universitet/Fasta tillståndets elektronik

    Author : Karl-Johan Hällgren; [2021]
    Keywords : radar; electronic warfare; jamming; jamming resistance; waveforms; phase codes; MIMO; radar; telekrig; störning; störskydd; vågformer; faskoder; MIMO;

    Abstract : In this report metrics for jamming resistance and radar performance of waveform sets are described and developed, and different sets of waveforms are optimized, evaluated and compared. It is shown that without additional processing or PRI jitter, waveform sets can reach jamming resistance a few dB worse than what is provided by PRI jitter alone, and together with PRI jitter a few dB better.
