Lyα absorber correlations contain information about the underlying density distribution associated with a particular class of absorbers. As such, they provide an opportunity to independently measure the “bias” of the Lyman alpha forest, i.e. the relationship between H I column density and underlying dark matter density. In these proceedings we use hydrodynamic simulations to investigate whether...

To design a high-quality vehicle shock absorber, the internal structure of piston assembly absorber is analyzed in this study. Using fluid–solid coupling method, high-precision flow grid model and solid finite element stacked valve are built analyzed. A bidirectional method proposed, which can be adopted to simulate analyze dynamic nonlinear response characteristics for slice Workbench software...

In this paper, the authors focus on presenting methodology for tuning optimization algorithm parameters, with a special evolutionary applications. The problem considered concerns phenomenon of nonlinear buckling automotive shock absorber, which itself is solved using commercial application finite element method (FEM) simulation. These analyses are usually time-consuming; therefore, decided to u...

Elastomeric proteins are molecular springs that confer excellent mechanical properties to many biological tissues and biomaterials. Depending on the role performed by the tissue or biomaterial, elastomeric proteins can behave as molecular springs or shock absorbers. Here we combine single-molecule atomic force microscopy and protein engineering techniques to create elastomeric proteins that can...

OBJECTIVES Despite many hypotheses, the pathophysiology of syringomyelia is still not well understood. In this report, the authors propose a hypothesis based on analysis of cerebrospinal fluid dynamics in the spine. METHODS An electric circuit model of the CSF dynamics of the spine was constructed based on a technique of computational fluid mechanics. With this model, the authors calculated h...
