  1. 1. Modeling and Estimation of Phase Noise in Oscillators with Colored Noise Sources

    Detta är en avhandling från Chalmers University of Technology

    Författare :Mohammad Reza Khanzadi; Chalmers tekniska högskola.; Chalmers University of Technology.; Chalmers tekniska högskola.; Chalmers University of Technology.; Chalmers tekniska högskola.; Chalmers University of Technology.; Chalmers tekniska högskola.; Chalmers University of Technology.; [2013]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Oscillator Phase Noise; Voltage-controlled Oscillator; Phase-Locked Loop; Colored Phase Noise; Phase Noise Model; Bayesian Cramer-Rao Bound; Maximum a Posteriori Estimator; Extended Kalman Filter Smoother; Mean Square Error.;

    Sammanfattning : The continuous increase in demand for higher data rates due to applications with massive number of users motivates the design of faster and more spectrum efficient communication systems. In theory, the current communication systems must be able to operate close to Shannon capacity bounds. LÄS MER

  2. 2. Assessing Soil Functions for Sustainable Remediation of Contaminated Sites

    Detta är en avhandling från Chalmers University of Technology

    Författare :Yevheniya Volchko; Chalmers tekniska högskola.; Chalmers University of Technology.; Chalmers tekniska högskola.; Chalmers University of Technology.; Chalmers tekniska högskola.; Chalmers University of Technology.; [2014]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Contaminated sites soil; minimum data set; remediation; soil functions; soil ecosystem services; soil quality indicators; sustainability assessment;

    Sammanfattning : Soil contamination is a worldwide problem. Soil remediation is often carried out to reduce the risks posed by contaminants in the soil to human health and environment. Contaminant concentration is typically the only soil quality aspect maintained in remediation projects. LÄS MER

  3. 3. Load and risk based maintenance management of wind turbines

    Detta är en avhandling från Chalmers University of Technology

    Författare :Pramod Bangalore; Chalmers tekniska högskola.; Chalmers University of Technology.; Chalmers tekniska högskola.; Chalmers University of Technology.; Chalmers tekniska högskola.; Chalmers University of Technology.; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Artificial neural network ANN ; condition monitoring system CMS ; life cycle cost; maintenance management; maintenance strategy; maintenance planning; optimization; supervisory control and data acquisition SCADA ; wind energy.;

    Sammanfattning : Wind power has proven to be an important source of renewable energy in the modern electric power systems. Low profit margins due to falling electricity prices and high maintenance costs, over the past few years, have led to a focus on research in the area of maintenance management of wind turbines.

  4. 4. Multi-scale characterisation of pasta - Effects of raw materials on water absorption, water distribution, and microstructure

    Detta är en avhandling från Chalmers University of Technology

    Författare :Thomas Steglich; RISE.; Chalmers tekniska högskola.; Chalmers University of Technology.; Chalmers tekniska högskola.; Chalmers University of Technology.; [2015]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; pasta; light microscopy; magnetic resonance imaging; microstructure; water distribution; texture properties; starch; gluten; bran; dietary fibre;

    Sammanfattning : Pasta is a product with a long history, but is also still being developed today. Producers want to use new raw materials to make pasta more nutritious, less allergenic, and less dependent on durum wheat. All have in common that new raw materials shall not compromise the desired texture properties of cooked pasta such as the “al dente” feeling. LÄS MER

  5. 5. In situ Studies of Platinum Catalyst Sintering

    Detta är en avhandling från Chalmers University of Technology

    Författare :Pooya Tabib Zadeh Adibi; Chalmers tekniska högskola.; Chalmers University of Technology.; Chalmers tekniska högskola.; Chalmers University of Technology.; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; platinum; catalyst deactivation; nanoparticle sintering; sintering kinetics; operando spectroscopy; indirect nanoplasmonic sensing; transmission electron microscopy;

    Sammanfattning : The damaging effect of pollutants from combustion engine exhaust on human health and environment is well recognized. Since the 70s, the three-way catalytic converter (TWC) has substantially improved the urban air quality by simultaneous conversion of CO, NOx and unburned hydrocarbons to O2, N2 and H2O. LÄS MER
