  2. 1. Reliability-based Assessment of Concrete Dam Stability

    Author : Marie Westberg; Avdelningen för Konstruktionsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; assessment; stability; concrete dam; structural reliability analysis; probability; uplift; system reliability;

    Abstract : Risk management is increasingly used in dam safety and includes risk analysis, risk evaluation and risk reduction. Structural Reliability Analysis (SRA) is a probabilistic methodology that may be used in the risk assessment process. READ MORE

  4. 2. Filament assembly and structural studies of intermediate filament like protein, FilP, in Streptomyces coelicolor

    Author : Ala Javadi; Linda Sandblad; Martin Thanbichler; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cytoskeleton; Intermediate filament-like; FilP; Streptomyces coelicolor; filament assembly; cryoelectron tomography; single particle analysis; crystallography; cellulose affinity;

    Abstract : The cytoskeleton, known as intracellular connected filaments, has a prominent role in cellular behavior, motility, and stability. The following three major types of polymers have been characterized as cytoskeleton in eukaryotes: microtubules that are 25 nm in diameter, actin filaments that are 7 nm in diameter, and intermediate filaments (IF) that are 10 nm in diameter.

  5. 3. Some Aspects of Wear and Structural Dynamics

    Author : Jakob Knudsen; Hållfasthetslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vibration and acoustic engineering; Mechanical engineering; hydraulics; chaos; interfacial breakdown; stability; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik; vacuum technology; fretting wear; fretting map; vibro-impact dynamics;

    Abstract : The topic of this thesis is dynamics and wear of structures. In the six appended papers different aspects of wear and dynamics of a model system are studied. The considered system consists of a long slender rod with unilateral supports, subject to harmonic and stochastic excitation. READ MORE

  6. 4. Community Robustness Analysis : Theoretical Approaches to Identifying Keystone Structures in Ecological Communities

    Author : Sofia Berg; Tomas Jonsson; Bo Ebenman; Daniel Stouffer; Linköpings universitet; []
    Keywords : ;

    Abstract : Most of the world’s ecosystems suffer from stress caused by human activities such as habitat destruction, fragmentation, overexploitation of species and climate change. These factors affect the reproduction and/or survival of individual species as well as interactions between species in ecological communities. READ MORE

  7. 5. A concrete dam assessment approach using probabilistic non-linear finite element analysis and scale model testing

    Author : Adrian Ulfberg; Gabriel Sas; Oisik Das; Jaime Gonzalez; Richard Malm; Fredrik Johansson; Marie Westberg Wilde; Leif Lia; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Finite element analysis; Scale model testing; Probabilistic analysis; Byggkonstruktion; Structural Engineering;

    Abstract : Dams are vital infrastructure for society as they provide various services (e.g., flood prevention, storage of byproducts from mining operations, water storage for irrigation and hydropower generation) by the impoundment of liquids. READ MORE
