  2. 11. Branch Identification in Elastic Stability Analysis

    Author : Anders Magnusson; Hållfasthetslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vacuum technology; hydraulics; Mechanical engineering; Produktionsteknik; Production technology; FEM; computer simulation; bifurcation; stability; vibration and acoustic engineering; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik;

    Abstract : In this thesis, methods to determine the static postbuckling behaviour of elastic structures undergoing large deformations, are considered and developed. Since the governing non-linear equations usually becomes too complex to be handled analytically, the main focus has been on developing methods that can be incorporated into a numerical solution scheme, such as the finite element method.

  5. 13. SOD1 Aggregation : Relevance of thermodynamic stability

    Author : Lisa Lang; Mikael Oliveberg; Michele Vendruscolo; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Aggregation; misfolding; Superoxide dismutase SOD1 ; Amyotrophic lateral sclerosis ALS ; unfolding; thermodynamic stability; Biochemistry; biokemi;

    Abstract : Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease affecting the upper and lower motor neurons causing muscle atrophy and paralysis followed by death. Aggregates containing superoxide dismutase (SOD1) are found as pathological hallmark in diseased ALS patients. READ MORE

  6. 14. On Stability and Surge in Turbocharger Compressors

    Author : Bertrand Kerres; Andreas Cronhjort; Mihai Mihaescu; Jörg Seume; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbocharger; Radial Compressor; Stability; Surge; Hurst exponent; Fractals; Machine Design; Maskinkonstruktion;

    Abstract : Turbochargers are used on many automotive internal combustion engines to increase power density. The broad operating range of the engine also requires a wide range of the turbocharger compressor. At low mass flows, however, turbo compressor operation becomes unstable and eventually enters surge.

  7. 15. 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
