ON A CLASS OF POSITIVE LINEAR OPERATORS
Journal Title: Journal of Science And Arts - Year 2012, Vol 21, Issue 4
Abstract
A new class of positive linear operators have been introduced which contains a number of well known positive linear operators such as Gamma-Operators of Muller, Post-Widder and Modi.ed Post-Widder Operators as particular cases.Some basic approximation properties of this class of operators have been studied in this paper.

OPTICAL PROPERTIES OF CdTe/CdS SOLAR CELLS DETERMINED BY INFRARED FOURIER TRANSFORMER (FTIR) SPECTROSCOPY
CdS/CdTe solar cells have attracted much attention as the most suitable candidate for thin-film compound solar cells, and research is being conducted to establish the viability of these devices. Although the films are po...
QUANTUM TUNNELLING AND MAGNETIZATION DYNAMICS IN LOW DIMENSIONAL SYSTEMS
Quantum mechanics allows a system to overcome a classically-unsurmountable energy barrier through a mechanism called Quantum Tunnelling (QT). Although pertaining to the quantum domain, QT is the cause of important physic...
