   Nyckelord :DGPS; short-term ice velocity; infinitesimal strain; Storglaciären; ablation area; DGPS; korttidsvariationer i isflöde; deformation; Storglaciären; ablationsområde;

   Sammanfattning : short time scale. Four differential GPS stations were installed in the lower ablation area of Storglaciären in Sweden for one week in August 2012. The position data over the period were then compared with the environment information including temperature, precipitation, known hydrology and topography. LÄS MER

   Sammanfattning : As many of the world’s nuclear power plants are near the end of their supposed life span a need arise to assess the components crucial to the safety of these plants. One of these crucial components is the concrete reactor confinement; to assess its condition, non-destructive testing (NDT) is an attractive method. LÄS MER
