    Sammanfattning : Images are an important data source in modern science and engineering. A continued challenge is to perform measurements on and extract useful information from the image data, i.e., to perform image analysis. LÄS MER

  4. 3. Hanging wall stability of sublevel caving mines in Sweden

    Författare :Alvaro Herdocia; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

    Sammanfattning : Mining with sublevel caving implies a drastic destruction of the ground surface in the area conforming the hanging wall of the mine. The extent of this affected zone is of little importance in unpopulated areas, but becomes of utmost economic significance when there are mine installations or a town site located on it. LÄS MER

  5. 4. Identification and characterisation of the novel mammalian gene family Elovl

    Författare :Abolfazl Asadi; Leif Andersson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; zoofysiologi; Zoological physiology;

    Sammanfattning : Comparative analysis is one of the foremost tools in biology. The most common comparative method is sequence alignment, which can be performed in many ways. By using any sort of alignments, competing sequences are evaluated by scoring schemes for estimating similarity. LÄS MER
