Abstract In this study, the stability dependence of turbulent Prandtl number ( $$Pr_t$$ P r t ) is quantified via a novel and simple analytical approach. Based on variance flux budget equations, hybrid length scale formulation fir...

The distribution in a niixed crystal A1-,B,C grown from an either (A, B)-rich or C-rich solution zone (e.g. travelling heater method or related techniques) is to be described by PFANN’S zone melting function which depends on the segregation coefficient and a characteristic length. Using pseudobinary mole fractions x the characteristic length of the distribution function is not the actual length...

In this paper, electrical characterization and modeling of conductive textiles are presented. A dedicated measurement setup has been developed to allow reliable connection of the textile samples with the equipment cables. Geometrical fabric structures and fabrication tolerances as well as high frequency properties up to 6 GHz for four types of textiles have been determined. Transmission lines w...

To an integral lattice L in the euclidean space (R, (, )), one associates the set of characteristic vectors v ∈ R with (v, x) ≡ (x, x) mod 2Z for all x ∈ L. They form a coset modulo 2L, where L = {v ∈ R | (v, x) ∈ Z ∀x ∈ L} is the dual lattice of L. Recall that L is called integral, if L ⊂ L and unimodular, if L = L. For a unimodular lattice, the square length of a characteristic vector is cong...
