  1. 16. Geological Structure and Time-Lapse Studies of CO2 Injection at the Ketzin Pilot Site, Germany

    Författare :Alexandra Ivanova; Christopher Juhlin; Milovan Urosevic; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : 3D seismic time-lapse surveys (“4D seismics”) are an essential tool for large scale reservoir characterization. The target reservoir of the Ketzin pilot project for CO2 storage is a saline aquifer of the heterogeneous Stuttgart Formation (Upper Triassic) in the Northeast German Basin. LÄS MER

  3. 17. Evaluation and Compensation of Nonlinear Distortion in Multicarrier Communication Systems

    Författare :Ali Behravan; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nonlinearity; Multicarrier communication systems; peak-to-average power ratio;

    Sammanfattning : In modern wireless communication systems with increasing data transfer rateand mobility, designing efficient transceivers is a key issue. Among differentchallenges, nonlinearity of high power amplifiers is a problem that has to beovercome by means of adding extra hardware or using more efficient signalprocessing algorithms. LÄS MER

  4. 18. System identification of large-scale linear and nonlinear structural dynamicmodels

    Författare :Vahid Yaghoubi Nasrabadi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Finite element model; Surrogate modeling; Bootstrapping; Polynomial chaos expansion; System identification; Exponential integration; Uncertainty quantification;

    Sammanfattning : System identification is a powerful technique to build a model from measurement data by using methods from different fields such as stochastic inference, optimization and linear algebra. It consists of three steps: collecting data, constructing a mathematical model and estimating its parameters. LÄS MER

  5. 19. Understanding didactic strategies based on the Laban-Malmgren technique when developing the technical and musical proficiency of singers

    Författare :Bo Rosenkull; Göteborgs universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; interpretive description; Jung; Laban; Laban-Malmgren technique; Malmgren; movement and singing; participatory action research; self-study; singing technique; Stanislavski; voice pedagogy; Yat Malmgren;

    Sammanfattning : In this thesis multiple methods were used to explore how the use of didactic strategies based on the LMT may enable a voice pedagogue to develop the technical and musical proficiency of singers who specialise in Western art music. Data for this qualitative study were collected by working with fourteen singers in South Africa and Sweden during workshops, masterclasses and individual lessons. LÄS MER

  7. 20. DSP based Chromatic Dispersion Equalization and Carrier Phase Estimation in High Speed Coherent Optical Transmission Systems

    Författare :Tianhua Xu; Sergei Popov; Gunnar Jacobsen; Jie Li; Seb Savory; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; coherent detection; chromatic dispersion; carrier phase estimation; quadrature phase shift keying; SRA - ICT; SRA - Informations- och kommunikationsteknik;

    Sammanfattning : Coherent detection employing multilevel modulation formats has become one of the most promising technologies for next generation high speed transmission systems due to the high power and spectral efficiencies. Using the powerful digital signal processing (DSP), coherent optical receivers allow the significant equalization of chromatic dispersion (CD), polarization mode dispersion (PMD), phase noise (PN) and nonlinear effects in the electrical domain.
