  1. 1. Nonlinear dynamics of flexible structures using corotational beam elements

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Thanh-Nam Le; KTH.; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; corotational method; nonlinear dynamics; large displacements; finite rotations; time stepping method; thin-walled cross-section; beam element;

    Abstract : 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. READ MORE

  2. 2. Molecular Evolution of the Vertebrate Genome

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Kiwoong Nam; Uppsala universitet.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In this thesis, I studied molecular evolution of the vertebrate genome, focusing on sex chromosomes, protein coding genes, and genome size variation. The evolutionary history of avian sex chromosomes was analyzed by comparing substitution rate among 12 gametologous gene pairs on the Z and W chromosomes. READ MORE

  3. 3. Electron transport properties of graphene and graphene field-effect devices studied experimentally

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Youngwoo Nam; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; dual-gated graphene field effect devices; thermopower; quantum Hall effect; graphene; Aharonov-Bohm effect; chemical vapour deposition;

    Abstract : This thesis contains experimental studies on electronic transport properties of graphene with the Aharonov-Bohm (AB) effect, thermopower (TEP) measurements, dual-gated graphene field effect devices, and quantum Hall effect (QHE). Firstly, in an effort to enhance the AB effect in graphene, we place superconducting-metal (aluminium) or normal-metal (gold) mirrors on the graphene rings. READ MORE

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Nam Nguyen Van; Lunds universitet.; Lund University.; [2011]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Vietnam; komparativ rätt; comparative law;

    Abstract : The thesis is written within the project Strengthening Legal Education in Vietnam.... READ MORE

  5. 5. Numerical Model of Beach Topography Evolution due to Waves and Currents: Special Emphasis on Coastal Structures

    University dissertation from Lund University (Media-Tryck)

    Author : Thanh Nam Pham; Lunds universitet.; Lund University.; [2010]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; morphodynamics; surface roller; wave-induced currents; random waves; sediment transport; coastal structures;

    Abstract : The beach topography change in the nearshore zone may be induced by natural phenomena such as wind, wave, storm, tsunami, and sea level rise. However, it can also be caused by man-made structures and activities, for example, groins, detached breakwaters, seawalls, dredging, and beach nourishment. READ MORE
