  1. 11. Weld Quality in Aluminium Alloys

    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : Rujira Ninni Deekhunthod; [2014]
    Keywords : Weld Aluminium Alloys MIG MAG;

    Abstract : The aims of this project are to present an understanding in what happens when aluminium-(Al) alloys are welded, and to investigate how the Mg-, Si- and Cr-contents in AA6005A influence the weld strength and cracking susceptibility. It is known that heat from welding affects the mechanical properties (strength) of the material. READ MORE

  3. 12. Evaluating and improving remembered sets in theHotSpot G1 garbage collector

    University essay from KTH/Skolan för datavetenskap och kommunikation (CSC)

    Author : ANDREAS SJÖBERG; [2014]
    Keywords : ;

    Abstract : In this master’s thesis project the remembered set implementation in Java HotSpot’s implementation of G1 is evaluated. It is verified by benchmarking that using Bloomfilters can reduce region scanning times when used as an intermediate data structure between card-precision bitmaps and region coarsening. READ MORE

  4. 13. Upper slope sedimentation environments in the Gaoping river-sea system of SW Taiwan

    University essay from Institutionen för geologiska vetenskaper

    Author : Lina Hansson; [2013]
    Keywords : Marine geology; sediment; Pb210; Grain size; Taiwan; hyperpycnal;

    Abstract : The Gaoping Slope, off the south west coast of Taiwan, is a tectonically active sedimentation environment attaining most of its sediment from the Gaoping River. This study examines sediment cores from two localities at 375 m and 495 m water depth by using X-radiography, Grain size- and 210Pb analysis, with the purpose of comparing the sedimentation environment at the two sites and examine how they were both affected by high sediment delivery during typhoon Morakot.

  5. 14. Coarsening of Simplicial Meshes for Large ScaleParallel FEM Computations with DOLFIN HPC : A parallel implementation of the edge collapse algorithm

    University essay from KTH/Numerisk analys, NA

    Author : Balthasar Reuter; [2013]
    Keywords : ;

    Abstract : Adaptive mesh refinement and coarsening methods are effective techniques to reduce the computation time of finite element based solvers. Parallel imple- mentations of such adaption routines, suitable for large scale computations on distributed memory machines, need additional care. READ MORE

  6. 15. Precipitation during Tempering of Martensite in Fe-Cr-C alloys

    University essay from KTH/Materialvetenskap

    Author : Chanachon Techaboonanek; [2012]
    Keywords : precipitation; microstructure; tempered martensite; Fe-C-Cr alloys; carbide; simulation;

    Abstract : The martensite structure is the most important microstructure in tool steel due to its high hardness. However, a lack of ductility is the major drawback. In order to improve the ductility and still maintaining a suitable hardness a tempering process is needed. READ MORE
