  1. 1. 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

  2. 2. 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.

  3. 3. Development of fuel efficiency improvements for a single cylinder internal combustion engine. An investigation and implementation of five fuel efficiency improving technologies on an Eco Marathon engine.

    Kandidat-uppsats, Chalmers tekniska högskola/Institutionen för tillämpad mekanik

    Författare :Adam Brandt; Anna Engelbrektsson; Niklas Hidman; Oskar Isaksson; Marcus Sandberg; Malin Settergren; [2015]
    Nyckelord :Internal combustion engine; Atkinson cycle; Variable compression; Air assisted direct injection; Laser ignition; Ceramic materials; Low friction materials; Low heat rejection engine; Chalmers Vera Team;

    Sammanfattning : This thesis describes the work of developing a technology demonstrating single cylinderengine for Chalmers Vera Team. The engine was to display five different technologies thatcould be of use to Chalmers Vera Team in the continued development of their fuel efficientengine. LÄS MER

  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
