  2. 1. Characterization and Correction of Analog-to-Digital Converters

    Author : Henrik Lundin; Peter Händel; Mikael Skoglund; Paolo Carbone; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; analog-to-digital converter; ADC; correction; post-correction; look-up table; characterization; calibration; Signal processing; Signalbehandling;

    Abstract : Denna avhandling behandlar analog-digitalomvandling. I synnerhet behandlas postkorrektion av analog-digitalomvandlare (A/D-omvandlare). A/D-omvandlare är i praktiken behäftade med vissa fel som i sin tur ger upphov till distorsion i omvandlarens utsignal. READ MORE

  4. 2. Automated static code analysis : A tool for early vulnerability detection

    Author : Dejan Baca; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Software vulnerabilities are added into programs during its development. Architectural flaws are introduced during planning and design, while implementation faults are created during coding. Penetration testing is often used to detect these vulnerabilities. READ MORE

  5. 3. Assessment of attenuation correction methods for quantitative neuro-PET/MR

    Author : Joao M. Sousa; Mark Lubberink; Lieuwe Appel; Håkan Ahlström; Mathias Engström; Ivo Rausch; Radiologi Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PET; MRI; attenuation correction; 68Ge transmission; quantification; 11C-PE2I; MRAC; DAT; CBF; Medicinsk radiofysik; Medical Radiophysics;

    Abstract : Hybrid PET/magnetic resonance (MR) can provide physiological, functional, and structural information simultaneously, facilitating research in neurological disorders. For quantitative PET, correction for photon attenuation (AC) is necessary. READ MORE

  6. 4. Time-lapse Analysis of Borehole and Surface Seismic Data, and Reservoir Characterization of the Ketzin CO2 Storage Site, Germany

    Author : Can Yang; Christopher Juhlin; Rob Arts; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Amplitude anomaly; AVO analysis; Carbon dioxide storage; Moving source profile survey; Reflection coefficient; Reservoir characterization; Static correction; Time-lapse analysis; Geophysics with specialization in Seismology; Geofysik med inriktning mot seismologi;

    Abstract : The CO2SINK (and CO2MAN) project is the first onshore CO2 storage project in Europe. The research site is located near the town of Ketzin, close to Potsdam in Germany. Injection started in June 2008, with a planned injection target of 100,000 tonnes of CO2. READ MORE

  7. 5. Modeling and post-correction of pipeline analog-digital converters

    Author : Samer Medawar; Peter Händel; Martin Gustafsson; KTH; []
    Keywords : ;

    Abstract : Integral nonlinearity (INL) for pipelined analog-digital converters (ADCs) operating at radio frequency is measured and characterized. A parametric model for the INL of pipelined ADCs is proposed and the corresponding least-squares problem is formulated and solved. READ MORE
