  2. 2. Frequency Transfer Techniques and Applications in Fiber Optic Communication Systems

    University dissertation from Chalmers University of Technology

    Author : Sven-Christian Ebenhag; RISE.; Chalmers tekniska högskola.; Chalmers University of Technology.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Time transfer; synchronization; UTC; optical fiber network; GPS carrier phase; synchronous optical networking SONET ; synchronous digital hierarchy SDH ; global positioning system GPS ; optical fiber;

    Abstract : Modern society is dependent on communications and the developments of these increases constantly through a seemingly endless demand for communication services and thereby synchronization and time. This is confirmed by a vast range of research on communications, irrespective of technology and protocol. READ MORE

  3. 3. Thick and Thin Ti2AlC Coatings

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Jenny Frodelius; Linköpings universitet.; Linköpings universitet.; RISE.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : This Thesis explores the deposition techniques of magnetron sputtering and high velocity oxy-fuel (HVOF) spraying for Ti2AlC as a promising high-temperature material. Magnetron sputtering aims at producing thin (≤1 μm) Ti2AlC films of high crystal quality for use as a model system in understanding the material’s basic properties. READ MORE

  4. 4. Computed tomography of sawlogs knot detection and sawing optimization

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Erik Johansson; Luleå tekniska universitet.; RISE.; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Träteknik; Wood Technology;

    Abstract : Branches on trees introduce defects on sawn timber called knots. By scanning sawlogs using computed tomography, knots can be detected and accounted for so that the sawing process can be optimized with respect to outgoing product value. READ MORE

  5. 5. Embedded Element Patterns in Combination with Circuit Simulations for Multi-Port Antenna Analysis

    University dissertation from Chalmers University of Technology

    Author : Kristian Karlsson; Högskolan i Jönköping.; RISE.; Chalmers tekniska högskola.; Chalmers University of Technology.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektrofysik; Electrophysics; Embedded element pattern; optimization; multi-port antenna; antenna arrays; antenna efficiency; correlation; antenna diversity; impedance matching; Greens function; reverberation chamber;

    Abstract : This thesis is a result from work on two different subjects, electromagnetic simulations of reverberation chambers and a methodology for the analysis of multi-port antennas. The subjects can be linked together by their contribution to knowledge in electromagnetic simulations and characterization of antennas. READ MORE
