  2. 1. Time Spectral Methods - Towards Plasma Turbulence Modelling

    Author : Kristoffer Lindvall; Jan Scheffel; Carl Sovinec; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Fusion; Turbulence; Micro-instabilities; Time-spectral; Navier-Stokes; MHD; Weiland model; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Energy comes in two forms; potential energy and kinetic energy. Energyis stored as potential energy and released in the form of kinetic energy. This process of storage and release is the basic strategy of all energy alternatives in use today. This applies to solar, wind, fossil fuels, and the list goes on. READ MORE

  4. 2. Timing Diagnostics and Coherent Harmonics from a test-FEL

    Author : Nino Cutic; Lunds universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Free electron laser; undulator radiation; coherent harmonic generation; circular polariyation; vacuum ultra-violet; seed pulse timing; bunch length; electro-optical spectral decoding;

    Abstract : The test free-electron laser (test-FEL) at MAX-lab in Lund demonstrated for the first time circularly polarized coherent femtosecond pulses at 66 nm wavelength. A 375 MeV electron bunch was seeded by a femtosecond laser at 263 nm and coherent harmonics were extracted in an APPLE-II type elliptical undulator. READ MORE

  5. 3. Clinical fluorescence cytometry : improvements to preparation methods and instrumentation

    Author : Thomas Heiden; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Fluorescence analysis; flow cytometry; image cytometry; DNA ploidy; proliferation; apoptosis; paraffin-embedded tissues; fresh tissues; S-phase fraction; debris; aggregates; spectral overlap; wavelength switching;

    Abstract : Fluorescence cytometry, which can be carried out by flow or image cytometry (FCM, ICM), provides a highly sensitive and specific tool for quantitative analysis of cell material. It is emerging from being a pure research method and becoming an important adjunct to clinical practice. To better realize its potential, more research is needed. READ MORE

  6. 4. The structure and conformation of saccharides determined by experiment and simulation

    Author : Roland Stenutz; B. Meyer; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chemistry; Kemi; Organic Chemistry; organisk kemi;

    Abstract : A computer program, CASPER, for sequence determination of oligosaccharides and regular polysaccharides using NMR-data, has been extended to support multiply branched structures. The program has been modified to allow the use of incomplete experimental data since spectral overlap can be a problem even at high fields. READ MORE

  7. 5. Multiuser Serially Concatenated Continuous Phase Modulation

    Author : Pär Moqvist; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : A multiuser communication system using serially concatenated and randomly interleaved continuous phase modulation (SCCPM) over the additive white Gaussian noise (AWGN) channel is investigated. The users, which may be asynchronous, are allowed to have individual energy levels as well as carrier frequencies and phases. READ MORE
