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

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

    Sammanfattning : 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. LÄS MER

  2. 2. David Helldén : modernistisk visionär på traditionens grund

    Författare :Martin Rörby; Riitta Nikula; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; David Helldén; Architecture; Modernism; Sweden; Hötorgscity; Sergels Torg; Stockholm University; Art; Konstvetenskap; konstvetenskap; History Of Art;

    Sammanfattning : Architect David Helldén (1905-1990) took part in the formation of some of the most well-known buildings and environs in Stockholm. Hötorgscity, Sergels Torg and the turquoise glass complex of Stockholm University at Frescati all bear his signature, as does Hökarängen Centre, which includes the first pedestrianised shopping street in Sweden.

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

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

    Sammanfattning : 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.

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

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

    Sammanfattning : 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. LÄS MER

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

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

    Sammanfattning : 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’.
