  1. 1. Thrust Performance and Heat Load Modelling of Pulse Detonation Engines

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Konstantin Ragozin; [2020]
    Nyckelord :Pulse Detonation; PDE; Heat Modelling; Thrust Modelling;

    Sammanfattning : Pulse Detonation Engines (PDEs) are propulsion systems that use repeated detonations to generate thrust. Currently in early stages of development, PDEs have been theorised to have advantages over current deflagration based engines. LÄS MER

  3. 2. Experimental Procedures for Operational Modal Analysis of a Power Pack on a Drill Rig

    Master-uppsats, Linköpings universitet/Mekanik och hållfasthetslära

    Författare :Oscar Nilsson; [2017]
    Nyckelord :Operational modal analysis; OMA; engine sweep; modal identication; harmonic scaling;

    Sammanfattning : All structures have modal properties such as natural frequencies and damping. In engineeringit is often of interest to estimate these modal properties for certain structures, to be used whenmodelling for example fatigue. This is done by computing them from finite element models, by using experimental measurements or both. LÄS MER

  4. 3. Peer to Peer Search Protocol

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Abhimanyu Babbar; [2015]
    Nyckelord :;

    Sammanfattning : Decentralized full-text search is still an unsolved problem in peer-to-peer research. As part of this thesis, we introduce Sweep, a fully decentralized full-text search engine built on Apache Lucene, that takes significant steps towards providing reliable, low-latency, and accurate search results.

  5. 4. Strontium -90 Radiation Detection

    Kandidat-uppsats, Mittuniversitetet/Avdelningen för elektronikkonstruktion

    Författare :Jingyi Jia; [2014]
    Nyckelord :Radiation; Strontium; Arduino; Processing;

    Sammanfattning : The objective of this thesis is to construct a measurement system, measuring Radiation from Strontium with mass number 90 ( 90 Sr). The absorbed beta particle has a kinetic energy of 546 keV. The constructed scanning system makes it possible to sweep over a larger area than the actual Silicon detector. The used detector has an area of 1cm 2 . LÄS MER

  7. 5. Experimental comparison of DI and PFI in terms of emissions and efficiencyrunning Ethanol-85

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Daniel Ottosson; Konstantinos Zioris; [2014]
    Nyckelord :;

    Sammanfattning : It has in recent year become more and more important to find an alternative to fossil fuel in our vehicles due to the increasing fuel price and to reduce their negative impact on the environment. One alternative is already in widespread use around the world, namely ethanol. LÄS MER
