MATHEMATICS AND MENTAL CALCULUS
Journal Title: Journal of Science And Arts - Year 2010, Vol 12, Issue 1
Abstract
This paper presents some great skills of both mathematicians and nonmathematicians in mental calculus. These information are important because the personalities we spoke about were very significant for their times and their work meant a lot for the progress of the mathematical science.

OPTICALLY ACTIVE BISMUTH HETEROBIMETALLIC COMPLEXES CONTAINING ALKALI METAL-CAPPED BINAPHTHOXIDE LIGATION
The reaction of monometallated (Li, Na, K) (R)-2,2’-dihydroxy-1,1’-binaphthyl (BINOL) with [Bi(OBut)3] affords optically pure bismuth tris(binaphthoxides) with three capping Group I counterions. The stable monomeric comp...
ON A PROPERTY OF THE SPLINE FUNCTIONS
The definition of the spline functions as solutions of a variational problem is presented in the preliminaries of this paper and are shown some theorems regarding to the existence and uniqueness. The main result of this...
THE STRUCTURAL INFLUENCE OF THE FORCES ON THE STABILITY OF DYNAMICAL SYSTEMS
In this paper consider the autonomous dynamical system linear or linearized with 2 degree of freedom. In the system of equation of 4th degree, appear the structure generalized forces: K(q) - the conservative forces...
A NON-DESTRUCTIVE METHOD FOR MEASUREMENT OF MOISTURE IN BUILDING MATERIALS
The measurement of moisture in porous building materials is an important issue in many situations. Especially in the case of the restoration of historical monuments, it is desirable to use non-destructive methods that ca...
OPERATION TRANSFORM FORMULAE FOR GENERALIZED FRACTIONAL HILBERT TRANSFORM
The generalized fractional Hilbert transform has many applications in several areas including signal processing. In this paper we have proved some Operation Transform Formulae for the generalized fractional Hilbert trans...
