  1. 1. The Importance of Radiation Damage for Molecular Reconstruction from FEL Diffraction Experiments

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Molekyl- och kondenserade materiens fysik

    Författare :Nicklas Bjärnhall Prytz; [2018]
    Nyckelord :Radiation damage; SFX; XFEL; Diffraction; Protein; Crystallography;

    Sammanfattning : Serial Femtosecond X-ray crystallography (SFX) is a rapidly growing experimental technique by which the structure of a crystalline sample may be determined. The X- rays arrive at the sample in pulse trains of the order of femtoseconds. LÄS MER

  2. 2. Architecture Designfor Compressed Sensing-Based Low Power Systems

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Giovanni Zamolo; [2016]
    Nyckelord :;

    Sammanfattning : In the Internet of Things scenario, a desirable feature of wireless sensors is the energy autonomy. However, the transmitter stage needs a great amount of energy to modulate and transmit the interested information. LÄS MER

  3. 3. Upgrading the Control and Monitoring system for the TOFOR neutron time-of-flight spectrometer at JET

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Johan Valldor-Blücher; [2013]
    Nyckelord :control and monitoring system; upgraded control and monitoring system; C Mu system; C M system; TOFOR; spectrometer; time-of-flight; JET; fusion; plasma diagnostics; energy spectrum; monitoring time delays; pulse reconstruction; timing measurements;

    Sammanfattning : This report describes the development and testing of the upgraded Control and Monitoring (C&Mu) system for the TOFOR neutron spectrometer. TOFOR is currently performing plasma diagnostics for the JET experimental fusion reactor. The purpose of the C&Mu system is to enable monitoring of the amplitude dependent time delays of TOFOR.

  4. 4. Enhancement of SAR Image Resolution with Implementation of Circular GB-SAR System

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Författare :Dheeraj Nehru Neravati; [2013]
    Nyckelord :Synthetic Aperture Radar; UWB; GB-SAR; Circular SAR; Circular Aperture; Resolution; Enhancement; Radar; GBP;

    Sammanfattning : Radars were used for surveillance and remote sensing but nowadays they handle a vast range of applications, radar imagery being one of them. The need for high resolution images was inevitable which lead to Synthetic Aperture Radar (SAR) systems. SAR plays a prominent role in remote sensing applications and geophysical studies. LÄS MER

  5. 5. Method for Acquisition and Reconstruction of non-Cartesian 3-D fMRI

    Magister-uppsats, Linköpings universitet/BildbehandlingLinköpings universitet/Tekniska högskolan

    Författare :Per Thyr; [2008]
    Nyckelord :MRI; PRESTO; PRESTO CAN; rotation; sequence development; image reconstruction; gridding; phase correction;

    Sammanfattning : The PRESTO sequence is a well-known 3-D fMRI imaging sequence. In this sequence the echo planar imaging technique is merged with the echo-shift technique. This combination results in a very fast image acquisition, which is required for fMRI examinations of neural activation in the human brain. LÄS MER
