  2. 6. Angle-resolved photoemission study of unconventional cuprate superconductors

    Author : Qinda Guo; Oscar Tjernberg; Andrea Damascelli; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Unconventional superconductivity; cuprate; high harmonic generation; narrow bandwidth light source; spherical grating based monochromator; time- and angle-resolved photoemission spectroscopy; Okonventionell supraledning; kuprat; hög övertonsgenerering; ljuskälla med smal bandbredd; sfäriskt gitterbaserad monokromator; tids- och vinkelupplöst fotoemissionsspektroskopi;

    Abstract : Understanding unconventional superconductivity remains one of the most important unsolved problems in physics. A particularly noteworthy case is the copper-based high-temperature superconductor, which stands out due to its remarkably high transition temperature and relatively simple structure. READ MORE

  4. 7. Sources and Diagnostics for Attosecond Science

    Author : Miguel Miranda; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Pulse Compression; High-order Harmonic Generation; Ultrafast; Ultrashort; Attosecond; Femtosecond; Pulse Characterization; Fysicumarkivet A:2012:Miranda;

    Abstract : Ultrafast science refers to physical events that happen on the femtosecond (1 fs=10^-15 s) and attosecond (1 as=10^-18 s) timescales. Generation of attosecond pulses is usually achieved by interacting high-intensity femtosecond pulses with matter (typically gases), in a process called high-order harmonic generation (HHG).

  5. 8. Flexible Receivers in CMOS for Wireless Communication

    Author : Anders Nejdel; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Consumers are pushing for higher data rates to support more services that are introduced in mobile applications. As an example, a few years ago video-on-demand was only accessed through landlines, but today wireless devices are frequently used to stream video. READ MORE

  6. 9. Direct RF sampling receivers for wireless systems in CMOS technology

    Author : Darius Jakonis; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : The fast development of wireless communication systems asks for more flexible and more cost-effective radio architectures. A long term goal is a software defined radio, where communication standards are chosen by reconfiguration of hardware. READ MORE

  7. 10. Models and Algorithms - with applications to vehicle tracking and frequency estimation

    Author : Joakim Gunnarsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; motion models; subspace methods; radar detections; Automotive; F-ESPRIT.; vehicle tracking; frequency estimation;

    Abstract : This thesis considers two different research problems; one concerned with the issue of tracking vehicles and one related to estimating frequencies in harmonic signals. The vehicle-tracking problem is addressed from the perspective of an automotive-safety application, which seeks to monitor the course of surrounding road users with the objective to make decisions regarding if, how and when to intervene.
