  1. 11. Robust Scalable Video Multicast and Performance Issues in Wireless LANs

    Författare :Daniel Forsgren; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap;

    Sammanfattning : The successful deployment of multimedia streaming services, over a multiservice IP-based heterogeneous infrastructure, requires resource-efficient, scalable and reliable network transport. This can be achieved using end-to-end methods, e.g. adaptive application-level source and channel coding. LÄS MER

  3. 12. Empirical Studies in Corporate Finance, Taxation and Investment

    Författare :Joakim Jansson; Otto Toivanen; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economics; Nationalekonomi; Economics; Nationalekonomi; nationalekonomi; Economics;

    Sammanfattning : This thesis consists of four self-contained essays. Essay 1 extends previous research focusing on firms' discrete external financing decision by adapting an estimation procedure accommodating both fixed effects and a lagged dependent variable. This makes it possible to establish the nature of the dependence. LÄS MER

  4. 13. A new approach for considering the interference impact on digital radio systems from complex interference environments

    Författare :Kia Wiklundh; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; minimum shift keying; class A; amplitude probability distribution; bandwidth conversion; Gaussian approximation; emission; non-Gaussian interference; performance estimation; man-made noise; measurement; emission requirements; micro-wave oven; MSK; coding gain; APD; interference;

    Sammanfattning : Interference from electrical equipment can severely degrade aco-located digital radio receiver. To avoid such performance degradation, it isnecessary to have estimation methods to predict the influence of an interferenceenvironment on a radio receiver. LÄS MER

  5. 14. DSP-based Coherent Optical Systems : Receiver Sensitivity and Coding Aspects

    Författare :Miu Yoong Leong; Sergei Popov; Gunnar Jacobsen; Soren Forchhammer; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : User demand for faster access to more data is at a historic high and rising. One of the enabling technologies that makes the information age possible is fiber-optic communications, where light is used to carry information from one place to another over optical fiber. LÄS MER

  7. 15. Development of the read-out link and control board for the ATLAS Tile Calorimeter Upgrade

    Författare :Eduardo Valdés Santurio; Samuel Bryant Silverstein; Costas Foudas; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; HL-LHC; ATLAS; Tile Calorimeter; TileCal; Demonstrator; Daughterboard; Read-out; Digital electronics; Data acquisition; Radiation tolerant; GBTx; TID; NIEL; SEU; SEL; FPGA; Kintex 7; Ultrascale; Ultrascale ; Optic Links; fysik; Physics;

    Sammanfattning : The Phase-II upgrade plan for the ATLAS Hadronic Tile Calorimeter facing the High-Luminosity LHC (HL-LHC) era includes approximately 1000 radiation tolerant read-out link and control boards (Daughterboards) that will provide full-granularity digital data to a fully-digital trigger system off-detector through multi-Gbps optic fibres. Different Daughterboard (DB) revisions have been developed, each successively aiming to meet the demanding HL-LHC requirements. LÄS MER
