  1. 16. A Chemometric Approach to Process Monitoring and Control - With Applications to Wastewater Treatment Operation

    Author : Christian Rosén; Industriell elektroteknik och automation; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robotics; Automation; Elektroteknik; Electrical engineering; wastewater treatment; supervisory control; simulation; process monitoring; principal component analysis PCA ; multivariate statistics; modelling; activated sludge; detection; control engineering; Automatiska system; robotteknik; reglerteknik; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp;

    Abstract : In this work, various aspects of multivariate monitoring and control of wastewater treatment operation are discussed. A number of important difficulties face operators and process engineers when handling online measurements from wastewater treatment processes. READ MORE

  2. 17. Long-term exposure to transportation noise in relation to metabolic and cardiovascular outcomes

    Author : Andrei Pyko; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Transportation noise exposure is increasing because of rapid urbanization and transportation growth. Environmental noise exposure affects a large part of the population and gives rise to widespread annoyance and sleep disturbances. READ MORE

  3. 18. The urban form and the sound environment - Tools and approaches

    Author : Laura Estévez Mauriz; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; road traffic noise; prediction; Urban sound planning; modelling; quiet side; urban systems; traffic dynamics;

    Abstract : Cities are always confronted with transition and adaptation. Awareness on urban environmental quality is leading the vision about the built environment’s resilience and sustainability, highlighting the importance of a multidisciplinary framework for urbanisation processes. READ MORE

  4. 19. Large Eddy Simulation of Turbulent Compressible Jets

    Author : Bernhard Semlitsch; Mihai Mihaescu; Laszlo Fuchs; Paul G. Tucker; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Compressible Flow; Large Eddy Simulation; Acoustic Noise Generation; Near-field Acoustics; Flow Control; Optimization; Modal Flow Decomposition; Engineering Mechanics; Teknisk mekanik;

    Abstract : Acoustic noise pollution is an environmental aggressor in everyday life. Aero- dynamically generated noise annoys and was linked with health issues. It may be caused by high-speed turbulent free flows (e.g. READ MORE

  5. 20. Sound field separation with microphone arrays

    Author : Elias Zea; Ines Lopez Arteaga; Mats Åbom; Leif Kari; Jean-Hugh Thomas; KTH; []
    Keywords : 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; Vehicle and Maritime Engineering; Farkostteknik;

    Abstract : 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. READ MORE
