  1. 1. Dynamic principles in craniofacial surgery. Expander elements in craniofacial surgery

    Author : Fredrik Gewalli; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Scaphocephaly; Brachycephaly; Dynamic cranioplasty; Pi-procedure; DCB; Expander elements; Distraction; Mental development; ICP; Cephalometry; Cephalic index;

    Abstract : Lannelongue & Lane described strip removal of ossified skull sutures in craniosynostosis in the 1890s. More complex osteotomies with bone grafting were developed during the 1960s. Dynamic techniques, utilizing force to direct the growing brain for skull reshaping was introduced by Jane 1978 with the p-plasty for sagittal synostosis. READ MORE

  2. 2. Regularization of Parameter Problems for Dynamic Beam Models

    Author : Sara Rydström; Börje Nilsson; Fredrik Berntsson; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Euler-Bernoulli beam equation; parameter identification; bending stiffness; refractive index; Tikhonov regularization; Applied mathematics; Tillämpad matematik; Mathematics; Matematik;

    Abstract : The field of inverse problems is an area in applied mathematics that is of great importance in several scientific and industrial applications. Since an inverse problem is typically founded on non-linear and ill-posed models it is a very difficult problem to solve. READ MORE

  3. 3. Exposure assessment for the prevention of musculoskeletal disorders

    Author : Istvan Balogh; Avdelningen för arbets- och miljömedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Yrkesmedicin; industrial medicine; Occupational health; heart rate; interindividual variation; index; arbetsmiljömedicin; job strain; Questionnaire; mechanical exposure;

    Abstract : Work-related musculoskeletal disorders of shoulder/neck are a major and increasing problem. Beside the pain, they involve high cost for the employer and society. The total expenditure for the musculoskeletal disorders of the neck and upper limb have been estimated to 0.5-2. READ MORE

  4. 4. Heterogeneous Bonded Particle Modelling of Rock Fracture

    Author : Albin Wessling; Jörgen Kajberg; Simon Larsson; Pär Jonsén; Timo Saksala; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rock; DEM; BPM; fracture; drilling; dynamic; Solid Mechanics; Hållfasthetslära;

    Abstract : The dynamic fracture process of rock materials is of importance for several industries, such as the rock drilling process in geothermal and mining applications. Gaining knowledge and understanding of dynamic rock fracture through numerical simulations can enhance the rock drilling process, for example by optimising the drill bit geometry and drilling parameters.

  5. 5. Pricing Portfolio Credit Derivatives

    Author : Alexander Herbertsson; Göteborgs universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Portfolio credit risk; intensity-based models; dynamic dependence modelling; default contagion; CDS; synthetic CDO tranches; index CDS; k-th-to-default swaps; CDS-correlation; default-correlation; Markov jump processes; multivariate phase-type distributions; matrix-analytic methods;

    Abstract : This thesis consists of four papers on dynamic dependence modelling in portfolio credit risk. The emphasis is on valuation of portfolio credit derivatives. The underlying model in all papers is the same, but is split in two different sub-models, one for inhomogeneous portfolios, and one for homogeneous ones. READ MORE
