  1. 1. Perfectly matched layers for second order wave equations

    Author : Kenneth Duru; Gunilla Kreiss; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Beräkningsvetenskap med inriktning mot numerisk analys; Scientific Computing with specialization in Numerical Analysis;

    Abstract : Numerical simulation of propagating waves in unbounded spatial domains is a challenge common to many branches of engineering and applied mathematics. Perfectly matched layers (PML) are a novel technique for simulating the absorption of waves in open domains. READ MORE

  3. 3. Historical Urban Agriculture : Food Production and Access to Land in Swedish Towns before 1900

    Author : Annika Björklund; Mats Widgren; Johannes Renes; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; urban agriculture; urban history; urban geography; Sweden; town; food production; food consumption; Uppsala; historical geography; land allocation; cadastral maps; urban land-use; Human geography; Kulturgeografi; Human Geography; kulturgeografi;

    Abstract : This doctoral thesis analyses the role of historical urban agriculture in a long-time perspective, through a combination of overarching surveys of Swedish towns and detailed studies of one town – Uppsala in east-central Sweden. The study shows how agricultural land – town land – of various sizes was donated to towns repeatedly during medieval times and in the 16th and 17th centuries. READ MORE

  4. 4. The morphology and evolutionary significance of the anomalocaridids

    Author : Allison Daley; Graham E. Budd; Nigel C. Hughes; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; anomalocaridids; Cambrian; Burgess Shale; exceptional preservation; palaeontology; Historical geology and palaeontology; Historisk geologi och paleontologi; Historical Geology and Paleontology; Historisk geologi och paleontologi;

    Abstract : Approximately 600 to 500 million years ago, a major evolutionary radiation called the “Cambrian Explosion” gave rise to nearly all of the major animal phyla known today. This radiation is recorded by various fossil lagerstätten, such as the Burgess Shale in Canada, where soft-bodied animals are preserved in exquisite detail. READ MORE

  5. 5. Experimental Vertical Axis Wind Turbine System

    Author : Jon Kjellin; Uppsala universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Vertical axis wind turbines may have mechanical advantages compared to conventional horizontal axis wind turbines, which make vertical turbines interesting to study. A 12 kW straight-bladed Darrieus turbine has been designed and constructed by the Division of Electricity at Uppsala University. READ MORE
