  2. 1. Evolution and taxonomy of Cambrian arthropods from Greenland and Sweden

    Author : Martin Stein; John S. Peel; Dieter Waloszek; David J. Siveter; Reinhardt M. Kristensen; David L. Bruton; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cambrian; Arthropods; Trilobites; Evolution; Greenland; Sweden; Historical geology and palaeontology; Historisk geologi och paleontologi;

    Abstract : Arthropods have a rich fossil record spanning the Phanerozoic. Biomineralized forms such as the extinct trilobites are particularly common and are proven index fossils for biostratigraphy. Forms with an unmineralized cuticle are more rare, preserved only in so called konservat lagerstätten. READ MORE

  4. 2. Electro-Acoustic and Electronic Applications Utilizing Thin Film Aluminium Nitride

    Author : David Michael Martin; J. Olsson; I. Katardjiev; S. Gevorgian; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; AlN; FBAR; FPAR; CMP; SOI; Nickel Silicide; Wafer Bonding; Electronics; Elektronik; Elektronik; Electronics;

    Abstract : In recent years there has been a huge increase in the growth of communication systems such as mobile phones, wireless local area networks (WLAN), satellite navigation and various other forms of wireless data communication that have made analogue frequency control a key issue. The increase in frequency spectrum crowding and the increase of frequency into microwave region, along with the need for minimisation and capacity improvement, has shown the need for the development of high performance, miniature, on-chip filters operating in the low to medium GHz frequency range.

  5. 3. Distributed Stochastic Programming with Applications to Large-Scale Hydropower Operations

    Author : Martin Biel; Mikael Johansson; Lennart Söder; David Woodruff; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stochastic programming; distributed; algorithms; large-scale; optimization; hydropower; software; julia language; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Stochastic programming is a subfield of mathematical programming concerned with optimization problems subjected to uncertainty. Many engineering problems with random elements can be accurately modeled as a stochastic program. In particular, decision problems associated with hydropower operations motivate the application of stochastic programming. READ MORE

  6. 4. For the Benefit of Everyone? : Explaining the Significance of Swedish Public Housing for Urban Housing Inequality

    Author : Martin Grander; David Clapham; Malmö universitet; []
    Keywords : Housing; Inequality; Social Housing; Universalism; Discretion; Structures of Housing Provision; Public Housing; Housing Regimes;

    Abstract : Housing has a special place in the Swedish welfare state. Ever since Gustav Möller, Minister for Social Affairs, in 1945 was handed the result of Bostadssociala utredningen, a state investigation on housing from a social perspective, housing has been a bearing pillar in the Swedish ‘Folkhem’.

  7. 5. Deposition of Al-doped ZnO films by high power impulse magnetron sputtering

    Author : Martin Mickan; David Horwat; Ulf Helmersson; Aline Rougier; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Transparent conducting oxides (TCOs) are an important class of materials with many applications such as low emissivity coatings, or transparent electrodes for photovoltaics and flat panel displays. Among the possible TCO materials, Al-doped ZnO (AZO) is studied due to its relatively low cost and abundance of the raw materials. READ MORE
