    Sammanfattning : 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. LÄS MER

  3. 3. Signal Processing for Radar with Array Antennas and for Radar with Micro-Doppler Measurements

    Detta är en avhandling från Karlskrona : Blekinge Tekniska Högskola

    Sammanfattning : Radar (RAdio Detection And Ranging) uses radio waves to detect the presence of a target and measure its position and other properties. This sensor has found many civilian and military applications due to advantages such as possible large surveillance areas and operation day and night and in all weather. LÄS MER

    Sammanfattning : Genetically structured populations arise when gene flow between groups of individuals is hindered by geographical, behavioural or temporal barriers. The identification of such groups is important for understanding evolution and has large implications for conservation concern. LÄS MER
