    Abstract : The rate at which stars have formed throughout the history of theuniverse is not constant, it started out slow, increased until around redshift ∼ 2 when it reversed and became slower again. The reason for this behaviour is still being investigated with various models and simulations usually based upon dark matter halos. READ MORE

  3. 2. Moisture Transport in PA6

    University essay from Lunds universitet/Hållfasthetslära; Lunds universitet/Institutionen för byggvetenskaper

    Author : Emanuel Markström; [2022]
    Keywords : Technology and Engineering;

    Abstract : Polyamide 6 (PA6) is known to absorb water from its environment due to its chemical structure. The water absorption leads to changes in the mechanical properties as well as an increase in volume (swelling) of the polyamide. READ MORE

  4. 3. Near-Surface Energy Balance on an Alpine Rock Glacier: Murtèl-Corvatsch

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Luisa Pruessner; [2017]
    Keywords : rock glaciers; energy balance; SNOWPACK; permafrost;

    Abstract : This project investigates the near surface energy balance on the Murt`el-Corvatsch rock glacier in the Upper Engadine, Swiss Alps, using the 1D physical SNOWPACK model. A correct representation of the near surface energy balance is important to predict the long term evolution of permafrost below rock glaciers. READ MORE

  5. 4. Investigation of granular materials deformations under an unconfined compaction with x-ray computed tomography.

    University essay from KTH/Väg- och banteknik

    Author : Zhu Li; [2013]
    Keywords : X-Ray Computed Tomography; Unconfined compaction; Digital image;

    Abstract : The behavior of the asphalt mixtures under large deformations, for example an unconfined compaction is of high practical importance. Quantitative measurement of the spatial distribution of internal structure of asphalt mixtures is crucial to study deformation behavior of asphalt mixtures. READ MORE
