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

    University essay from Institutionen för fysik och astronomi

    Author : Johan Valldor-Blücher; [2013]
    Keywords : 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;

    Abstract : 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.

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

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

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

    Abstract : 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. READ MORE

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

    University essay from Bildbehandling; Tekniska högskolan

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

    Abstract : 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. READ MORE

  5. 14. Modelling and Design of Oversampled Delta-Sigma Noise Sharpers for D/A Conversion

    University essay from Institutionen för systemteknik

    Author : Vikram Singh Parihar; [2005]
    Keywords : Electrical engineering; Oversampled Delta- Sigma Noise shapers; Elektroteknik; elektronik och fotonik;

    Abstract : This thesis demonstrates the high- level modelling and design of oversampled delta- sigma noise shapers for D/A conversion. It presents an overview and study on digital- to- analog converters (DAC) followed by the noise shapers. It helps us to understand how to design a noise shaper model and algorithmic expressions are presented. READ MORE
