  2. 16. Multiparty Quantum Communication and fs-laser Written Integrated Optics Circuits

    Author : Ashraf Mohamed El Hassan; Mohamed Bourennane; Guillermo Andler; Marcos Curty; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Quantum optics; quantum communication; quantum cryptography; fs-laser written waveguides; integrated optics circuits; Physics; fysik;

    Abstract : Quantum information science, the rapidly developing interdisciplinary field,  gives power to the information and communications technologies (ICT) by  providing secure communication, precision measurements, ultra-powerful simulation and ultimately computation. It is well known that photons are an ideal candidate for encoding the quantum bit, or "qubit", in quantum information and specially for quantum communication. READ MORE

  4. 17. CMOS circuits for digital RF systems

    Author : Ingemar Söderquist; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : This thesis describes some high performance CMOS circuits and architectures developed for digital signal processing of Radio Frequency (RF) signals. Experimental results are demonstrated in a generic radar jammer architecture. READ MORE

  5. 18. The hepatitis B virus – Insights into genetic variability, evolution and Bayesian phylogeographic inference

    Author : Mikael Ingman; Malmö Klinisk virologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hepatit B; evolutionsbiologi; fylogeni; Hepatitis B; evolutionary dynamics; Phylogeography;

    Abstract : In terms of genome size, the hepatitis B virus is the smallest virus known to infect humans and its compactness with multiple overlapping reading frames puts restraints on the emergence of mutations. In the papers included in this thesis we aimed to investigate genetic variation within the precore and core promoter region and to describe the origin, spread and diversification of HBV genotype A.

  6. 19. Description and Analysis of Data and Errors in GPS Meteorology

    Author : Borys Stoew; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; atmospheric water vapor; global positioning system; propagation delay; meteorology; ensemble assimilation; GPS;

    Abstract : This report presents the relation between remote sensing techniques used for estimation of atmospheric water vapor content, and numerical weather prediction. The thesis makes an overview of the methods for estimation of the zenith wet/total delay (ZWD/ZTD) for radio waves in the neutral atmosphere, and a statistical description of data in relation to the sampling problem for atmospheric water vapor.

  7. 20. Energy-Centric Scheduling for Real-Time Systems

    Author : Flavius Gruian; Institutionen för datavetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; numerisk analys; Datalogi; Computer science; numerical analysis; System-Level Synthesis; Variable Speed Processors; Dynamic Voltage Scaling; Real-Time Scheduling; Energy Efficient Systems; control; systems; system; kontroll;

    Abstract : Energy consumption is today an important design issue for all kinds of digital systems, and essential for the battery operated ones. An important fraction of this energy is dissipated on the processors running the application software. To reduce this energy consumption, one may, for instance, lower the processor clock frequency and supply voltage. READ MORE
