  1. 1. The An-Archical State : Logics of Legitimacy in the Social Contract Tradition

    Author : Sofia Näsström; Bo Lindensjö; Stephen K White; Stockholms universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; legitimacy; social contract; state; responsivity; anarchy; dissent; subjectivity; freedom; action; Levinas; Arendt; Political science; Statsvetenskap;

    Abstract : The modern state is today under great pressure. In the face of globalization, many theorists seek to rethink the boundaries of the state. They call for a transformation of the state from the national to the global level. But there is a deeper theoretical question at stake. READ MORE

  2. 2. Ultrasensitive Cold-Electron Bolometer

    Author : Ian Jasper Agulo; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; responsivity; electron cooling; cold-electron bolometer CEB ; SIN tunnel junctions; superconducting cold-electron bolometer SCEB ; noise equivalent power;

    Abstract : The Cold-Electron Bolometer (CEB) is an ultrasensitive device designed for the detection of cosmic microwave background radiation. The key to its sensitivity is the electron cooling of the absorber by the superconductor-insulator-normal metal (SIN) tunnel junction. READ MORE

  3. 3. Infrared Photodetectors based on Nanowire Arrays with Embedded Quantum Heterostructures

    Author : Mohammad Karimi; NanoLund: Center for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Nanowires; infrared photodetectors; intersubband nanowire photodetector; quantum discs-in-nanowire; high responsivity;

    Abstract : Optical sensors operating in the infrared range of the electromagnetic spectrum are key components in a variety ofapplications including optical communication, night vision, medical diagnosis, surveillance, and astronomy.Semiconductor nanowires have great potential for realizing broadband infrared photodetectors with excellentresponsivity, low dark current and low noise, and a unique compatibility with commercial silicon-based electronics.

  4. 4. Novel Terahertz Emitters and Detectors: InGaAs Slot Diodes and InAs Self-Switching Diodes

    Author : Andreas Westlund; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; InAs; InGaAs; slot diode; self-switching diode; zero-bias diode;

    Abstract : Two novel types of diodes for emission and detection of THz radiation have been investigated. The diodes are based on high electron mobility III-V heterostructures. Both diodes are aimed for room-temperature operation, for which there is a demand for new THz technology. For emission, slot diodes based on an InGaAs heterostructure were studied. READ MORE

  5. 5. Staging Science : Some aspects of the production and distribution of science knowledge

    Author : Piotr Szybek; Pedagogik; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; hermeneutics; phenomenology; philosophy of education; history and philosophy of science; ethical and political aspects; science curriculum; school science; Education; science education; life-world; Pedagogy and didactics; Pedagogik; didaktik;

    Abstract : The dissertation presents a phenomenological view on the interaction between science knowledge and prescientific knowledge. Drawing on Husserl, Merleau-Ponty and Lévinas the human bodily grounded existence is described, the central feature of this existence being its responsivity to the Other. READ MORE
