most of the contour detection methods suffers from some drawbacks such as noise, occlusion of objects, shifting, scaling and rotation of objects in image which they suppress the recognition accuracy. to solve the problem, this paper utilizes zernike moment (zm) and pseudo zernike moment (pzm) to extract object contour features in all situations such as rotation, scaling and shifting of object i...

Kashihara[2] defined the Pseudo-Smarandache function Z by m(m+l) } Properties of this function have been studied in [1], [2] etc. 1. By answering a question by C. Ashbacher, Maohua Le proved that S(Z(n»-Z(S(n» changes signs infmitely often. Put d s,z (n) = I S(Z(n»-Z(S(s» I We will prove first that lim inf d s,z (n) ~ 1 (1) n-oo and (2) n-+oo p(p+l) Indeed, let n = , where p is an odd prime. Th...

Ginger waste material (GWM) has been utilized as adsorbent for removal of hazardousPatent Blue VF (PBVF) dye from aqueous solution. Batch adsorption experiments wereperformed as a function of pH, contact time, dye concentration, adsorbent dose and temperature.The optimum pH required for the maximum adsorption was found to be 2. The experimentalequilibrium adsorption data were tested using Langm...

The RP 2 gauge model which allows interpolation between the RP 2 and O(3) spin models is studied in 2D. We use Monte-Carlo renormalization techniques for blocking the mean spin-spin interaction, 〈A〉, and the mean gauge field plaquette, 〈P 〉. The presence of the O(3) renormalized trajectory is verified and is consistent with the known three-loop β-function. The first-order ‘vorticity’ transition...

We survey current term-wise techniques for quadratizing high-degree pseudo-Boolean functions and introduce a new one, which allows multiple splits of terms. We also introduce the first aggregative approach, which splits a collection of terms based on their common parts.

Three important properties in aggregation theory are investigated, namely horizontal min-additivity, horizontal max-additivity, and comonotonic additivity, which are defined by certain relaxations of the Cauchy functional equation in several variables. We show that these properties are equivalent and we completely describe the functions characterized by them. By adding some regularity condition...
