  1. 1. Investigating Gas Turbulence in Galactic Discs

    Master-uppsats, Lunds universitet/Astronomi

    Författare :Timmy Ejdetjärn; [2019]
    Nyckelord :galaxies; gas; turbulence; interstellar medium; star formation; feedback; gravitational instability; local; high redshift; Physics and Astronomy;

    Sammanfattning : The interstellar medium of both local and distant disc galaxies is observed to be supersonically turbulent and the turbulent motion of the gas is thought to be important for galaxy formation and evolution, particularly as a key ingredient for star formation. Consequently, this generates a striking relation between the star formation rate (SFR) and gas velocity dispersion ($\sigma_{\rm g}$; a measurement on the level of turbulence). LÄS MER

  2. 2. RF BiST för att detektera IQ-imbalanser avseende överhörningseffekter för avancerade antennsystem

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

    Författare :Kishore Khed; [2018]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Internet of Things (IoT) is a network constituted by uniquely identifiable commodity objects or devices equipped with some sensing system. To achieve high data rates required for IoT devices, a modern wireless communication system, known as Advanced Antenna Systems(AAS), leads to significant improvement, by increasing not only the data rate but also spectrum efficiency and the channel capacity.

  3. 3. En ekonomisk analys av att använda en Quartzenebaserad puts vid energieffektivisering av äldre q-märkta byggnader.

    M1-uppsats, Högskolan i Gävle/Avdelningen för bygg- energi- och miljöteknik; Högskolan i Gävle/Avdelningen för bygg- energi- och miljöteknik

    Författare :Anton Fredriksson; Christoffer Fors Edman; [2017]
    Nyckelord :Energy efficiency; Q-label buildings; thermal insulation plaster; Quartzene; LCC; Energieffektivisering; q-märkta byggnader; värmeisolerande puts; Quartzene; LCC.;

    Sammanfattning : Older q-labeled buildings may not be changed according to the corruptions banning, resulting in difficulties in energy efficiency of q-marked buildings, as traditional energy efficiency methods cannot be used without altering the building's properties. This report examines the profitability to energy-efficient a q-labeled building with a heat insulating plaster based on Z1 quartzene and lime cement render. LÄS MER

  4. 4. Waveform Generator Implemented in FPGA with an Embedded Processor

    Uppsats för yrkesexamina på grundnivå, Linköpings universitet/Institutionen för systemteknik

    Författare :Anna Goman; [2003]
    Nyckelord :Electronics; Waveform Generator; I Q mixing; FPGA; Virtex; MicroBlaze; Embedded Development Kit; VHDL; Elektronik;

    Sammanfattning : Communication and digital signal processing applications of today are often developed as fully integrated systems on one single chip and are implemented as application specific integrated circuits using e.g. VLSI technology. LÄS MER
