  2. 11. Reconfigurable and Wideband Receiver Components for System-on-Chip Millimetre-Wave Radiometer Front-Ends

    Author : Shakila Bint Reyaz; Robert Malmqvist; Anders Rydberg; Luca Roselli; Uppsala universitet; []
    Keywords : Reconfigurable; Wideband; Receivers; Millimetre-Wave; Radiometers; System-on-Chip; Passive Imaging.; Engineering Science with specialization in Microwave Technology; Teknisk fysik med inriktning mot mikrovågsteknik;

    Abstract : This thesis presents solutions and studies related to the design of reconfigurable and wideband receiver circuits for system-on-chip (SoC) radiometer front-ends within the millimetre-wave (mm-wave) range. Whereas many of today’s mm-wave front-ends are bulky and costly due to having discrete RF components, single-chip receiver modules could potentially result in a wider use for emerging applications such as wireless communication, short range radar and passive imaging security sensors if realised with adequate performances and at a lower cost.

  4. 12. Integrated Antennas : Monolithic and Hybrid Approaches

    Author : Erik Öjefors; Anders Rydberg; Sayan Mukherjee; Duixian Liu; Uppsala universitet; []
    Keywords : Electronics; antenna travelling wave arrays; antenna phased arrays; phase shifters; micromachining; silicon; monolithic microwave integrated circuits; dipole antennas; loop antennas; slot antennas; Elektronik;

    Abstract : This thesis considers integration of antennas and active electronics manufactured on the same substrate. The main topic is on-chip antennas for commercial silicon processes, but hybrid integration using printed circuit board technology is also addressed. READ MORE

  5. 13. Äventyrets tid : den sociala äventyrsromanen i Sverige 1841-1859

    Author : Anders Öhman; Umeå universitet; []
    Keywords : HUMANIORA; HUMANITIES; social-adventure novel; popular literature; romance; history of the novel; the study of plot; Mikhail Bakhtin; Carl Fredrik Ridderstad; Viktor Rydberg; Carl Jonas Love Almqvist;

    Abstract : The subject of this thesis is the social-adventure novel which was popular in the 1840s and early 1850s in Sweden. In contrast to literary critics who have tended to regard the thrilling plot of the genre as merely a way of creating effects, I try to analyze the plot as a bearer of both meaning and ideology.

  6. 14. Chemical Bonding of Hydrocarbons to Metal Surfaces

    Author : Henrik Öström; Anders Nilsson; Phil Woodruff; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Adsorption; hydrocarbon; core-level; spectroscopy; Physics; Fysik;

    Abstract : Using x-ray absorption spectroscopy (XAS), x-ray emission spectroscopy (XES) and x-ray photoelectron spectroscopy (XPS) in combination with density functional theory (DFT) the changes in electronic and geometric structure of hydrocarbons upon adsorption are determined. The chemical bonding is analyzed and the results provide new insights in the mechanisms responsible for dehydrogenation in heterogeneous catalysis. READ MORE
