This paper studies numerical integration (or cubature) over the unit sphere S2 ⊂ R3 for functions in arbitrary Sobolev spaces Hs(S2), s > 1. We discuss sequences (Qm(n))n∈N of cubature rules, where (i) the rule Qm(n) uses m(n) points and is assumed to integrate exactly all (spherical) polynomials of degree ≤ n, and (ii) the sequence (Qm(n)) satisfies a certain local regularity property. This lo...

pose changes, the distribution of skin colors in color planes is very employ color histogram based approaches to skin color segmentation. sis of skin colors directly in the RGB color space. Our idea is simple observation that skin colors of a person in the RGB color space are linear fashion, we apply PCA techniques to RGB values of skin colors s collected online. The axis along which the data i...

Attention is given to the initial-boundary-value problems (IBVPs) ut + ux + uux + uxxx = 0, for x, t ≥ 0, u(x, 0) = φ(x), u(0, t) = h(t)  (0.1) for the Korteweg-de Vries (KdV) equation and ut + ux + uux − uxx + uxxx = 0, for x, t ≥ 0, u(x, 0) = φ(x), u(0, t) = h(t)  (0.2) for the Korteweg-de Vries-Burgers (KdV-B) equation. These type of problems arise in modeling waves generated by a wa...

An understanding of dynamic processes of proteins on the electrode surface could enhance the efficiency of bioelectronics development and therefore it is crucial to gain information regarding both physical adsorption of proteins onto the electrode and its electrochemical property in real-time. We combined high-speed atomic force microscopy (HS-AFM) with electrochemical device for simultaneous o...

We introduce a new formal logic, called equality propositional logic. It has two basic connectives, $boldsymbol{wedge}$ (conjunction) and $equiv$ (equivalence). Moreover, the $Rightarrow$ (implication) connective can be derived as $ARightarrow B:=(Aboldsymbol{wedge}B)equiv A$. We formulate the equality propositional logic and demonstrate that the resulting logic has reasonable properties such a...
