  2. 2. Sound field separation with microphone arrays

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Elias Zea; KTH.; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sound field separation; Microphone arrays; Near-field acoustic holography; Reflecting surfaces; Railway rolling noise; Farkostteknik; Vehicle and Maritime Engineering;

    Sammanfattning : Sound field analysis is a fundamental tool in the design, manufacturing, testing and diagnosis of machines and transportation means, as well as the legislations that regulate noise levels in order to minimize environmental pollution. Customary solutions to the problem of sound field analysis are microphone array technologies such as near-field acoustic holography (NAH) and beamforming. LÄS MER

    Sammanfattning : This thesis aims to assess the environmental consequences of management strategies for wood waste in Sweden. There is a special focus on separation strategies and in what way such measures influence environmental aspects such as the presence of heavy metals in the waste. LÄS MER

  4. 4. Conditions and constraints for waste management : collection, characterisation and producer responsibility in Sweden

    Detta är en avhandling från Göteborg : Chalmers tekniska högskola

    Författare :Cecilia Mattsson Petersen; Högskolan Dalarna.; [2004]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; collection; household waste; landfill ban; producer responsibility; source separation; waste characterisation; waste component analysis; waste management;

    Sammanfattning : Waste management has changed from being mainly a question of transporting out of sight to being an issue entwined in all parts of society, from product planning to the private domestic sphere. This has imposed new conditions and constraints for waste management, the description of which is the objective of this thesis. LÄS MER
