Chaos viscosity and turbulent viscosity II

Shibata, Hiroshi - In: Physica A: Statistical Mechanics and its Applications 276 (2000) 3, pp. 441-447

Chaos viscosity which was considered in the previous paper is extended so that the decomposed components of the … chaos viscosity is expressed explicitly by the use of the function of the nonlinear term in the equation of motion …

Chaos viscosity and turbulent viscosity

Shibata, Hiroshi - In: Physica A: Statistical Mechanics and its Applications 274 (1999) 3, pp. 476-483

Chaos or turbulence induces a viscosity by the contraction of motion. The driven damped pendulum which shows chaos is … rewritten in the form that has viscosity derived from the nonlinear term. It is shown that the fluctuation–dissipation theory … which takes account of the chaos viscosity has smaller low-frequency power and larger high-frequency power compared to the …

Determination of the density and the viscosities of biodiesel–diesel fuel blends

Alptekin, Ertan; Canakci, Mustafa - In: Renewable Energy 33 (2008) 12, pp. 2623-2630

In this study, commercially available two different diesel fuels were blended with the biodiesels produced from six different vegetable oils (sunflower, canola, soybean, cottonseed, corn oils and waste palm oil). The blends (B2, B5, B10, B20, B50 and B75) were prepared on a volume basis. The key...

Explicit characterization of the super-replication strategy in financial markets with partial transaction costs

Bouchard, Bruno; Ben Tahar, Imen - Université Paris-Dauphine (Paris IX) - 2007

We consider a continuous time multivariate financial market with proportional transaction costs and study the problem of finding the minimal initial capital needed to hedge, without risk, European-type contingent claims. The model is similar to the one considered in Bouchard and Touzi [B....
