  1. 6. Determining the effects of regulatory parameters on the structural dynamics of P-type ATPase membrane transporters

    Författare :Fredrik Orädd; Magnus Andersson; Magnus Wolf-Watz; Marco Cammarata; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; protein dynamics; regulation; time-resolved x-ray solution scattering; MD simulation; membrane protein; P-type ATPase; SERCA; CopA; HMA4; adenylate kinase; Physical Chemistry; fysikalisk kemi;

    Sammanfattning : Proteins are macromolecular machines with roles in all cellular activities and structures. The functional properties of each protein is the result of its combination of 3D-structure and inherent dynamics, and a wealth of structural and dynamic mechanisms have evolved to regulate protein activity.

  3. 7. Adaptive Finite Element Procedures in Structural Dynamics

    Författare :Xiangdong Li; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; finite element; h-adaptivity; Newmark method; structural dynamics; space-time; a posteriori; superconvergent patch recovery; postprocessing; automatic time-stepping; semidiscretization; error estimation; discontinuous Galerkin;

    Sammanfattning : This thesis deals with a posteriori error estimation and adaptivity in finite element procedures for the analysis of structural dynamic problems. First, error estimation and adaptivity for the Newmark time integration method are studied. LÄS MER

  4. 8. Carbody and Passengers in Rail Vehicle Dynamics

    Författare :Pelle Carlbom; KTH; []
    Nyckelord :Rail-Vehicle Dynamics; Human-Body Dynamics; Ride Comfort; Structural Dynamics;

    Sammanfattning : The carbody plays an important role in rail vehicle dynamics.This thesis aims atdeveloping validated modelling methods tostudy its dynamics, how it is excited on trackand how itinteracts with the passengers. The primary interest is ridecomfort,considering vibrations up to 20 Hz. LÄS MER

  5. 9. Timber-concrete hybrid structural systems : Examples, long and short-term dynamic monitoring, and numerical analysis

    Författare :Carl Larsson; Michael Dorn; Åsa Bolmsvik; Thomas K. Bader; Henrik Danielsson; Linnéuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Timber-Concrete Hybrid Structures; Timber Design; Structural Dynamics; Structural Health Monitoring; Byggteknik; Civil engineering;

    Sammanfattning : Timber-concrete hybrid buildings are an innovative solution to increase the amount of timber materials in modern buildings. Due to its lower impact on the environment than materials like steel and concrete, the demand for timber products is rising as the construction industry aims to decrease its environmental footprint.
