  2. 1. Food for Thought. Communication and the transformation of work experience in web-based in-service training

    Author : Mona Nilsen; Göteborgs universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; in-service training; food production industry; quality assurance; computer-mediated communication; chat interaction; digital technologies; appropriation; mediation; communicative strategies; framing; footing; hybrid learning activity;

    Abstract : The background of the present study is an interest in the use of digital technologies for in-service training activities in industry. Globalization, international competition and transnational production are elements that currently transform work practices and work organizations. READ MORE

  4. 2. Footing with Settlement-Reducing Piles in Non-Cohesive Soil

    Author : Duc Long Phung; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Although the design concept based on the idea of limiting the settlement of footings by settlement-reducing piles is gaining more and more support, there have been very few experimental studies of the behaviour of piled footings in non-cohesive soil. The influences of the contact between the pile cap and the soil on the capacity and the load-settlement behaviour of a piled footing are considerable but this has not been well understood. READ MORE

  5. 3. Towards a relativistically covariant many-body perturbation theory - With numerical implementation to helium-like ions

    Author : Daniel Hedendahl; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; many-body perturbation theory; bound state QED; helium-like ions; Green s operator; covariant evolution operator; combined effects of QED and correlation; atomic structure calculations;

    Abstract : The experimental results for simple atomic systems have become more and more accurate and in order to keep up with the experimental achievements the theoretical procedures have to be refined. Recent accurate experimental results obtained for helium-like ions in the low- and moderate-Z regions proclaim the importance of theoretical calculations that combines relativistic, QED and electron correlation effects.

  6. 4. Spatiotemporal carrier dynamics in graphene

    Author : Roland Jago; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; spatiotemporal dynamics; density matrix formalism; graphene; relaxation dynamics; carrier multiplication; Bloch equations; photoconduction effect; bolometric effect;

    Abstract : Graphene as an atomically thin material exhibits remarkable optical and electronic properties that suggest its technological application in novel optoelectronic devices, such as graphene-based photodetectors and lasers. To understand the properties of such devices on a microscopic level, we study the interplay of optical excitation, carrier-carrier, carrier-phonon, and carrierphoton scattering as well as diffusion processes.

  7. 5. A generalized quantum chemical approach for nano- and bio-electronics

    Author : Jun Jiang; Yi Luo; Sven Stafström; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biotechnology; Bioteknik; Bioengineering; Bioteknik;

    Abstract : A generalized quantum chemical approach for electron transport in molecular devices is developed. It allows to treat the devices where the metal electrodes and the molecule are either chemically or physically bonded on equal footing. READ MORE
