  1. 16. Area Efficient ADC for Low Frequency Application

    Master-uppsats, Linköpings universitet/Elektroniska Kretsar och System; Linköpings universitet/Tekniska högskolan

    Författare :Abdul Wahab Sami; [2014]
    Nyckelord :Cyclic ADC; Sample and Hold; Multiply-By-Two-Amplifier; Bottom Plate Sampling; OTA; Area; Low power.;

    Sammanfattning : Analog to digital converters (ADCs) are the fundamental building blocks in communication systems. The need to design ADCs, which are area and/or power efficient, has been common. Various ADC architectures, constrained by resolution capabilities, can be used for this purpose. LÄS MER

  3. 17. Organic-inorganic hybrid perovskites as light absorbing/hole conducting material in solar cells

    Uppsats för yrkesexamina på avancerad nivå, Fysikalisk kemi

    Författare :Saman Ghanavi; [2013]
    Nyckelord :;

    Sammanfattning : Solar cells involving two different perovskites were manufactured and analyzed. The perovskites were (CH3NH3)PbI3 and (CH3NH3)SnI3. Both perovskites have a shared methyl ammonium group (MA) and are used as both light absorbing material and hole conducting material (HTM) in this project. LÄS MER

  4. 18. Parametric Study to understand Ethanol Partially Premixed Combustion

    Magister-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Marcus Lundgren; [2012]
    Nyckelord :Ethanol premixed combustion; Technology and Engineering;

    Sammanfattning : As global concern increases regarding pollution does the demand to develop more ecient and environmental friendlier propulsion system come in high focus. The main systems for transportation have been dominated by the Otto and Diesel engine for a long time, but both are trade-o in local and global emissions, i.e. NOX, soot, HC and CO versus CO2.

  5. 19. Experimental analysis of variable capacity heat pump system equipped with vapour injection and permanent magnet motor

    Master-uppsats, KTH/Tillämpad termodynamik och kylteknik

    Författare :Umer Khalid Awan; [2012]
    Nyckelord :heat pump; variable capacity; scroll compressor; vapour injection; permanent magnet motor; R410A;

    Sammanfattning : This study analyzes the performance of variable capacity heat pump scroll compressor which is equipped with vapour injection and permanent magnet motor. Refrigerant used in the system is R410A. The study is divided in two phases. In first phase, tests are carried out for heat pump without vapour injection. LÄS MER

  7. 20. Introduction of water to reduce NOx emissions

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Martin Axelsson; [2009]
    Nyckelord :;

    Sammanfattning : Bakgrunden till detta examens arbete är behovet av att få lägre emissioner och då speciellt NOx emissioner. I detta arbete är olika NOx reduktions metoder beskrivna och utvärderade. Tyngdpunkten har lagts på de ”våta NOx reduktions teknologierna” och då speciellt teknologier för att befukta insugsluften.
