  1. 1. Structural assessment procedures for existing concrete bridges : Experiences from failure tests of the Kiruna Bridge

    Författare :Niklas Bagge; Björn Täljsten; Paulo Cruz; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anchorage; carbon fibre reinforced polymers; concrete; existing bridges; finite element analysis; flexure; full-scale test; load-carrying capacity; residual prestress force; punching; safety verification; shear; structural assessment; structural behaviour; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : Assessing existing bridges is an important task in the sustainable management ofinfrastructure. In practice, structural bridge assessments are usually conducted usingtraditional and standardised methods, despite knowledge that these methods oftenprovide conservative estimates. LÄS MER

  3. 2. Structural Studies of Large dsDNA Viruses using Single Particle Methods

    Författare :Hemanth Kumar Narayana Reddy; Martin Svenda; Sarah Butcher; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; PR772; phage; PRD1; Bacteriophage; coliphage; Melbournevirus; Cedratvirus; lurbo; Pithovirus; CryoEM; Single particle imaging; Coherent; Diffractive; Imaging; Soft X-ray; Microscopy; Microscope; GDVN; High resolution; XFEL; aerosol; Injection; electrospray; gas dynamic virtual nozzle; CDI; CXI; FEL; Chemistry with specialization in Biophysics; Kemi med inriktning mot biofysik;

    Sammanfattning : Structural studies of large biological assemblies pose a unique problem due to their size, complexity and heterogeneity. Conventional methods like x-ray crystallography, NMR, etc. are limited in their ability to address these issues. To overcome some of these limitations, single particle methods were used. LÄS MER

  4. 3. Structural and evolutionary aspects of stochastic processes

    Författare :Olof Görnerup; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Proto-cells.; Emergence; Self-organization; Coarse graining; Model reduction; Hierarchical dynamics; Pre-biotic evolution; Complexity;

    Sammanfattning : Stochastic processes constitute a broad class of objects of central importance in complex systems. The main structural aspect of stochastic processes that is treated in this thesis is their hierarchical dynamics. LÄS MER

  5. 4. On the Design of Functionally Integrated Aero-engine Structures: Modeling and Evaluation Methods for Architecture and Complexity

    Författare :Visakha Raja; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Product Architecture; Aero-engine Structures; Configurable Components; Load Paths; Design Product Complexity; Functionally Integrated Product Architecture; Product Development; Structural Complexity; Function–Means Modeling;

    Sammanfattning : The drive for airplanes with radically reduced fuel consumption and emissions motivates engine manufacturers to explore innovative engine designs. The novelty of such engines results in changed operating conditions, such as newly introduced constraints, increased loads or rearranged interfaces. LÄS MER

  7. 5. Unveiling Mechanistic Details of Macromolecular Interactions: Structural Design and Molecular Modelling of DNA-Protein Systems in Their Active State

    Författare :Anna Reymer; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; molecular modelling; intercalation; homologous recombination; DNA; ruthenium II polypyridyl compounds; human Rad51;

    Sammanfattning : Molecular structure is fundamental for understanding mechanisms of molecular interactions. This applies not least to understanding biological function: every biological cell, whether bacterial or human, is an immensely complex system of thousands of molecules that exist in constant motion and interaction with each other.
