   Abstract : In this report, we study how finite differences can be used to simulate acoustic wave propagation originating from a point source in the ocean using the Helmholtz equation. How to model sediment layers and the vast size of the ocean is studied in particular. READ MORE

3. 2. Towards stimuli-reformable paperboard and flipped classroom in chemistry education : A study of how to create a paper with controllable mechanical properties and a study in how the flipped classroom is used in chemistry education

   University essay from KTH/Skolan för teknikvetenskaplig kommunikation och lärande (ECE)

   Author : David Pettersson; [2017]

5. 4. Observed Ice Supersaturated Layers over Sweden and Implications for Aviation Induced Contrails over the Baltic Sea

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

   Author : Elin Björklund; [2011]
   Keywords : -;

   Abstract : In the atmosphere vertical extended layers that are in the state of super saturation with respect to ice can appear; these layers have been termed ice-supersaturated layers (ISSL). If an aircraft passes through an ISSL, persistent condensation trails can form. READ MORE
