  1. 1. Deep Autoencoders for Compression in High Energy Physics

    Master-uppsats, Lunds universitet/Partikelfysik; Lunds universitet/Fysiska institutionen

    Författare :Eric Wulff; [2020]
    Nyckelord :ATLAS; hadron jet; machine learning; autoencoder; dimensionality reduction; artificial intelligence; high energy physics; data compression; Physics and Astronomy;

    Sammanfattning : Current technological limitations make it impossible to store the enormous amount of data produced from proton-proton collisions by the ATLAS detector at CERN's Large Hadron Collider. Therefore, specialised hardware and software is being used to decide what data, or which proton-proton \textit{collision events}, to save and which to discard. LÄS MER

  2. 2. The Information Bottleneck : Connections to Other Problems, Learning and Exploration of the IB Curve

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Borja Rodriguez Galvez; [2019]
    Nyckelord :;

    Sammanfattning : In this thesis we study the information bottleneck (IB) method. This is an informationtheoretic framework which addresses the question of what are the relevant factors of arandom variable X to explain another statistically dependent random variable Y . Thesefactors are embedded into a bottleneck variable T obeying the Markov condition Y $X $ T. LÄS MER

  3. 3. Effect of additional compression features on h.264 surveillance video

    Kandidat-uppsats, Mittuniversitetet/Avdelningen för informationssystem och -teknologi

    Författare :Erik Comstedt; [2017]
    Nyckelord :Video stream; compression; frame rate; GOP; surveillance;

    Sammanfattning : In video surveillance business, a recurring topic of discussion is quality versus data usage. A higher quality allows for more details to be captured at the cost of a higher bit rate, and for cameras monitoring events 24 hours a day, limiting data usage can quickly become a factor to consider.

  4. 4. Signal Processing for mmWave MIMO Radar

    Master-uppsats, Högskolan i Gävle/Avdelningen för elektronik, matematik och naturvetenskap

    Författare :Óscar Faus García; [2015]
    Nyckelord :radar; automotive; MIMO; CW; 79 GHz; short-range radars SRR ; millimeter wave; CFAR; simulations; phase modulation; algorithms; system gain;

    Sammanfattning : This thesis addresses the design study, implementation and analysis of signal processing algorithms for a 79 GHz millimeter-wave Phase Modulated Continuous Wave (PMCW) Multi Input Multi Output (MIMO) short range radar; performed in IMEC research institute (Leuven, Belgium). The radar system targets high resolution performance with low power consumption in order to integrate a full MIMO radar transceiver with digital processor and antennas in a compact package featuring a size of 1 cm2.

  5. 5. Inverkan av flisig krossballast på betong

    Uppsats för yrkesexamina på avancerad nivå, KTH/Betongbyggnad; KTH/Betongbyggnad

    Författare :Amer Halabi; Tor Grimlund; [2013]
    Nyckelord :concrete; coarse aggregate; flakiness; packing factor; workability; rheology; strength; betong; grovballast; flisighet; packningsgrad; arbetbarhet; reologi; hållfasthet;

    Sammanfattning : Concrete is one of the world’s most common construction materials and is composed of 70-80 % stone material. Today crushed stone is used as aggregate in concrete in order to replace natural aggregates due to strong environmental reasons. LÄS MER
