1. 1. Causal links of past climate change in Coupled Model Intercomparison Project Phase 5 climate models

   Författare :Thanh Le; MERGE: ModElling the Regional and Global Earth system; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; solar forcing; volcanic forcing; greenhouse gases radiative forcing; Granger causality; near-surface air temperature; ENSO; IOD; CMIP5; North Atlantic;

   Sammanfattning : The climate system is influenced by various external forcings (e.g. volcanic forcing, solar forcing and change of greenhouse gas concentrations) and its own internal climate variability. LÄS MER

3. 2. Nonlinear dynamics of flexible structures using corotational beam elements

   Författare :Thanh-Nam Le; Jean-Marc Battini; Reijo Kouhia; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; corotational method; nonlinear dynamics; large displacements; finite rotations; time stepping method; thin-walled cross-section; beam element;

   Sammanfattning : The purpose of this thesis is to develop corotational beam elements for the nonlinear dynamic analyse of flexible beam structures. Whereas corotational beam elements in statics are well documented, the derivation of a corotational dynamic formulation is still an issue. LÄS MER

4. 3. Corotational formulation for nonlinear analysis of flexible beam structures

   Författare :Thanh Nam Le; Jean-Marc Battini; Jari Mäkinen; KTH; []
   Nyckelord :Corotational method; nonlinear dynamic analysis; beam element; large displacements; finite rotations; time stepping method; cubic interpolations;

   Sammanfattning : Flexible beam structures are popular in civil and mechanical engineering. Many of these structures undergo large displacements and finite rotations, but with small deformations. Their dynamic behaviors are usually investigated using finite beam elements. A well known method to derive such beam elements is the corotational approach. LÄS MER

5. 4. Defining strong ownership: Institutional Determinants and Stakeholder Interests in Vietnamese Development Planning

   Författare :Thi Le Thanh Nguyen Forsberg; Ekonomisk-historiska institutionen; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Social and economic history; and Vietnam.; poverty reduction; foreign aid; development politics; development ownership; political institutions; Ekonomisk och social historia;

   Sammanfattning : The current development debate emphasizes national ownership of the development agenda as a precondition for sustainable development and aid effectiveness. Vietnam is often held up as a good example of strong ownership. Yet, the ownership concept is not clearly defined or understood due to a lack of empirically rooted evidence and analysis. LÄS MER

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

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

   Sammanfattning : 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. LÄS MER
