  2. 1. High-Performance Finite Element Methods : with Application to Simulation of Diffusion MRI and Vertical Axis Wind Turbines

    Author : Van-Dang Nguyen; Johan Hoffman; Johan Jansson; Axel Målqvist; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; High performance finite element method; computational diffusion MRI; turbulent flow; vertical axis wind turbine.; Computer Science; Datalogi;

    Abstract : The finite element methods (FEM) have been developed over decades, and together with the growth of computer engineering, they become more and more important in solving large-scale problems in science and industry. The objective of this thesis is to develop high-performance finite element methods (HP-FEM), with two main applications in mind: computational diffusion magnetic resonance imaging (MRI), and simulation of the turbulent flow past a vertical axis wind turbine (VAWT).

    Abstract : Background InVietnam, the proportion of people aged 60 and above has increased rapidly in recent decades. The majority live in rural areas where socioeconomic status is more disadvantaged than in urban areas.Vietnam’s economic status is improving but disparities in income and living conditions are widening between groups and regions.

  6. 4. Soil Degradation of Raised-beds on Orchards in the Mekong Delta Field and Laboratory Methods

    Author : Quang Pham Van; Per-Erik Jansson; Khoa Le Van; Ingmar Messing; KTH; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; citrus orchards; nutrient; soil fertility; soil strength; soil degradation; alluvial soil; Mekong delta;

    Abstract : Soil degradation is a complex process which may occur anywhere and at any time. It directly affects the physical, chemical and biological processes within the soil profile. Soil degradation can either be as a result of natural hazards or due to manmade actions, such as mismanagement on cropping patterns, soil preparation and cultivation practices. READ MORE
