We present a Chebyshev-type characterization for the best uniform approximations of periodic continuous functions by functions of the class M = ff(x) : f(x) = Z 2 0 K(x; y)h(y) dy; jh(y)j 1 a: e:; y 2 0; 2)g; where K(x; y) is a strictly cyclic variation diminishing kernel. x1 Introduction Let W r 1 a; b] be the Sobolev class of functions in C r?1 a; b] whose (r?1)st derivative is absolutely con...

We report high-power and single-frequency operation of a continuous-wave singly resonant potassium titanyl phosphate (KTiOPO(4)) optical parametric oscillator in a ring-cavity configuration. The ring singly resonant optical parametric oscillator threshold is 4.3 W. When the oscillator is pumped by 6.7 W of 532-nm radiation from an 11.2-W single-frequency resonantly doubled Nd:YAG laser, 1.9 W o...

To have a uniform distribution of reactants is an advantage to fuel cell. We report results for such distributor with tree-like flow field plates (FFP). Numerical simulations shown that the width scaling parameters patterns in FFPs used polymer electrolyte membrane cells (PEMFC) reduces viscous dissipation channels. In this study, experimental investigations were conducted on 2-layer FF plate p...

Context. Studies of the stellar and H I gas kinematics in dwarf low surface brightness (LSB) galaxies are essential for deriving constraints on their dark matter distribution. Moreover, a key component to unveil evolution LSBs is determine why some them can be classified as superthin. Aims. We aim investigate nature proto-typical superthin galaxy Fourcade-Figueroa (FF) understand role played by...
