  1. 1. Radar and sea clutter simulation with Unity 3D game engine

    M1-uppsats, Linköpings universitet/Programvara och system

    Författare :Mikael Johnsson; Linus Bergman; [2023]
    Nyckelord :radar simulation; sea clutter simulation; game engine; Unity; ray tracing; compute shader; graphics programming; GPU; radarsimulering; sjöklottersimulering; spelmotor; Unity; strålspårning; compute shader; grafisk programmering; GPU;

    Sammanfattning : Game engines are well known for their use in the gaming industry but are starting to have an impact in other areas as well. Architecture, automotive, and the defence industry are today using these engines to visualise and, to some extent, test their products. LÄS MER

  3. 2. ISAR Imaging Enhancement Without High-Resolution Ground Truth

    Master-uppsats, Linköpings universitet/Datorseende

    Författare :Moltas Enåkander; [2023]
    Nyckelord :SAR; SAR Imaging; ISAR; ISAR Imaging; Machine learning; Convolutional neural network; CNN; neural network; Super resolution; Unsupervised learning;

    Sammanfattning : In synthetic aperture radar (SAR) and inverse synthetic aperture radar (ISAR), an imaging radar emits electromagnetic waves of varying frequencies towards a target and the backscattered waves are collected. By either moving the radar antenna or rotating the target and combining the collected waves, a much longer synthetic aperture can be created. LÄS MER

  4. 3. An online study of L2 relative clause processing: Evidence from self-paced reading in Persian learners of English

    Master-uppsats, Lunds universitet/Allmän språkvetenskap; Lunds universitet/Masterprogram: Språk och språkvetenskap

    Författare :Abdolnoor Khaleghi; [2022]
    Nyckelord :relative clause; online L2 processing; second language comprehension; attachment preference; self-paced reading; heuristic processing; good-enough approach; working memory span.; Languages and Literatures;

    Sammanfattning : This study examines relative clause (RC) processing in Persian learners of English and native speakers of English to explore whether or how different task demands, referential context information with three potential RC antecedents along with the variables noun type (definite, indefinite), RC length (short, long) and RC type (extraposed, non-extraposed) affect their processing, using both an online non-cumulative self-paced reading task and an offline questionnaire. In the self-paced reading task, the online processing of RC attachment resolution was examined when participants read temporarily ambiguous sentences with RCs preceded by one clause or two clauses containing three NPs followed by comprehension questions to explore L2 RC attachment preferences.

  5. 4. Deformationsmätning av kubhörnsreflektorer med fotobaserad skanning och terrester laserskanning

    Kandidat-uppsats, Högskolan i Gävle/Samhällsbyggnad

    Författare :Mathias Erkkilä; Torkel Pettersson; [2022]
    Nyckelord :close-range photogrammetry; terrestrial laser scanning; deformation measurement; corner reflectors; InSAR; fotobaserad skanning; Terrester laserskanning; deformationsmätning; kubhörnsreflektor; InSAR;

    Sammanfattning : Kubhörnsreflektorer används som måltavlor med kontinuerlig och identifierbar reflekterad signalstyrka vid fjärranalys, bland annat för tekniken ”interferometric synthetic aperture radar” [InSAR]. Kubhörnsreflektorer tillämpas exempelvis för bevakning av sättningar i jordytan och kalibrering av [SAR]-system (”synthetic aperture radar”). LÄS MER

  7. 5. Developing Random Compaction Strategy for Apache Cassandra database and Evaluating performance of the strategy

    Master-uppsats, Blekinge Tekniska Högskola

    Författare :Roop Sai Surampudi; [2021]
    Nyckelord :Apache Cassandra; Compaction; Random Probability Distributions; IBM Cloud; NoSQL databases;

    Sammanfattning : Introduction: Nowadays, the data generated by global communication systems is enormously increasing.  There is a need by Telecommunication Industries to monitor and manage this data generation efficiently. Apache Cassandra is a NoSQL database that manages any formatted data and a massive amount of data flow efficiently. LÄS MER
