  1. 1. Multichannel Audio Signal Processing : Room Correction and Sound Perception

    Författare :Adrian Bahne; Anders Ahlén; Lars-Johan Brännmark; Mathias Johansson; Peter Händel; Uppsala universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; Audio signal processing; multichannel sound reproduction; equalizers; human sound perception; room correction; Electrical Engineering with specialization in Signal Processing; Elektroteknik med inriktning mot signalbehandling;

    Sammanfattning : This thesis concerns and combines multichannel sound reproduction, digital room correction, audio signal processing, and human sound perception. It investigates perceived sound quality and new methods to improve timbral and spatial fidelity of loudspeaker-based multichannel sound reproduction in reverberant environments. LÄS MER

  2. 2. Improvements in Bioimpedance Spectroscopy Data Analysis : Artifact Correction, Cole Parameters and Body Fluid Estimation

    Författare :Rubén Buendía López; Högskolan i Borås; []
    Nyckelord :Bioimpedance; Cole; Body Fluid; Medicinteknik;

    Sammanfattning : The estimation of body fluids is a useful and common practice in the status assessment of disease mechanisms and treatments. Electrical bioimpedance spectroscopy (EBIS) methods are non-invasive, inexpensive, and efficient alternatives for the estimation of body fluids. LÄS MER

  3. 3. Ions in cold electrostatic storage devices

    Författare :Peter Reinhed; Henning Schmidt; Henrik Cederquist; Jason Greenwood; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Atomic and molecular physics; Atom- och molekylfysik; Physics; fysik;

    Sammanfattning : We have constructed a compact purely electrostatic ion-beam trap, ConeTrap, which we have mounted inside a double-walled vacuum chamber. In the inner vacuum chamber, we can obtain ultra-high vacuum (UHV) conditions and reach thermal equilibrium at well controlled temperatures down to 10 K. LÄS MER

  4. 4. Acoustic modelling and testing of advanced exhaust system components for automotive engines

    Författare :Sabry Allam; Hand Bodén; Antonio Torregrosa; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Theoretical physics; acoustic modelling; testing; two-port; diesel particulate filter; after treatment device; Teoretisk fysik; Physics; Fysik;

    Sammanfattning : The increased use of the diesel engine in the passenger car, truck and bus market is due to high efficiency and lower fuel costs. This growing market share has brought with it several environmental issues for instance soot particle emission. LÄS MER

  5. 5. Defining Reality in Virtual Reality: Exploring Visual Appearance and Spatial Experience Focusing on Colour

    Författare :Beata Stahre Wästberg; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; architectural visualization; Virtual Reality; light; colour appearance; Visual appearance; Virtual Environment; simulation; spatial experience;

    Sammanfattning : Today, different actors in the design process have communication difficulties in visualizing and predictinghow the not yet built environment will be experienced. Visually believable virtual environments (VEs) can make it easier for architects, users and clients to participate in the planning process. LÄS MER
