  1. 11. A Vision Based Sensor System For Spacecraft Relative Navigation

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

    Författare :Sebastian Stauch; [2016]
    Nyckelord :;

    Sammanfattning : Docking is one of the crucial key elements in many aerospace applications and missions where despite all endeavors and precautions accidents and incidents occur far too often. Those events can lead in the worst case scenario to a total loss of the space system and payload. LÄS MER

  3. 12. Quality of experience for adaptive streaming using HTTP Dynamic Streaming

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Stefan Johansson; Daniel Norén; [2015]
    Nyckelord :HTTP TCP streaming; Adaptive steaming; HDS; no reference method; PI; QoE; Linear Bitrate.; Technology and Engineering;

    Sammanfattning : This thesis investigates how to establish the relationship between OSI layer 7 parameters of video streaming and the QoE of the user, and to evaluate which methods are most tting for the estimation of QoE. The project is made in cooperation with LTH and Acreo, and is a part of the Next generation over-the-top multimedia services (NOTTS) 7and the Eco system for Future Media Distribution (EFRAIM) project.

  4. 13. The impact of stumps’ height on secondary spread of Heterobasidion parviporum in precommercial thinning stands of Norway spruce (Picea abies)

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Iwona Urban; [2015]
    Nyckelord :Norway spruce; Heterobasidion parviporum; precommercial thinning; wysokość pnia; świerk pospolity; czyszczenia późne;

    Sammanfattning : The economic losses caused by Heterobasidion spp. infection is an important issue in the Swedish forestry sector where Scots pine and Norway spruce make up to 80% of the standing volume. Both of the fungi species naturally existing in Sweden: H. annosum and H. LÄS MER

  5. 14. DATA LINK LAYER SECURITY PROBLEMS AND SOLUTIONS

    Kandidat-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Ali Mustafa; Nasir Siddique; Mubeen Zubair; [2015]
    Nyckelord :data link layer;

    Sammanfattning : The Open Systems Interconnect Model (OSI) is a conceptual model of networking thatcategorizes network functions into seven layers. It is defined in this model that how layerscommunicate with each other. In this thesis, we address common Layer 2 attacks and theirsolutions. Layer 2 is considered a very weak link in a secure network. LÄS MER

  7. 15. Modulation Coding In A Radio Link And Data Transfer Application Using L2 VPN Ethernet Over MPLS In A Large Network

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

    Författare :Dogan Varli; [2015]
    Nyckelord :Radio Link; Path Loss; GNS3; QAM; MPLS;

    Sammanfattning : In this thesis work, the locations where we are unable to reach via fiber are considered for wireless transmission links. In the practical part of this thesis different modulation techniques and antenna sizes were analyzed  in order to provide the most efficient way of data transmission. LÄS MER
