  1. 1. Integrated Frequency Synthesis for Convergent Wireless Solutions

    Författare :Jad G. Atallah; Mohammed Ismail Elnaggar; Erik Bruun; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wireless; transceiver; Bluetooth; DECT; GSM; 3G; LTE; WLAN; WiMAX; multi-standard; vertical handover; Sniffer; frequency synthesizer; phase-locked loop; PLL; sigma-delta; calibration; Electronics; Elektronik;

    Sammanfattning : Wireless transceivers combining several standards in one unit are of key importance. In order to reach the ultimate goal of maximizing the performance-to-cost ratio of such modules, a careful study of the target application, the architecture, and the frequency planning is strongly required.

  3. 2. Remote Measurements of Ship Emissions

    Författare :Niklas Berg; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; airborne; Ship emissions; sulphur dioxide; nitrogen dioxide; DOAS; in situ measurements; carbon dioxide;

    Sammanfattning : The combustion of sulphur-containing fossil fuels gives rise to emissions of sulphurdioxide. Nitrogen oxides are also emitted when fuels are burned. The InternationalMaritime Organization (IMO) has ratified regulations regarding Sulphur Fuel Content(SFC) and NOx emissions from the shipping sector. LÄS MER

  4. 3. Methane production in dairy cows : individual cow variability in methane production

    Författare :Edward Hernando Cabezas Garcia; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Enteric methane (CH4) emissions vary between individual cows, and this variation is attributed to both animal and dietary factors. In addition, measurement technique of in vivo CH4 emissions from individual animals still represents a major challenge for successful emissions mitigation strategies. LÄS MER

  5. 4. Reuse and Recycling of Food Packaging - Odour Related Aspects of the Use and Misuse of PET Beverage Bottles

    Författare :Heléne Widén; Avdelningen för livsmedel och läkemedel; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Livsmedelsteknik; Food and drink technology; aroma transfer; reuse; recycling; migration; contaminants; post consumer material; food packaging; polyethylene terephthalate PET ;

    Sammanfattning : The reuse and closed-loop recycling of food packaging was studied in order to assess consumer safety and the sensory quality (e.g. taste and smell) of packaged food. LÄS MER

  7. 5. Remote Measurements of Gas and Particulate Matter Emissions from Individual Ships

    Författare :Jörg Beecken; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; pollution; compliance monitoring; shipping; ship emission; particle emissions; identification of polluting ships; emission factors;

    Sammanfattning : Shipping significantly contributes to the world's anthropogenic emissions of sulfur, nitrogen species and particulate matter. These species affect the global radiative forcing as well as local acidification, eutrophication and human health. LÄS MER
