MAGNETORESISTANCE-TEMPERATURE RELATIONSHIP: CALCULUS OF VARIATION APPROACH
Journal Title: Journal of Science And Arts - Year 2011, Vol 17, Issue 4
Abstract
To account for the varied index of power law Tn for temperature (T) dependence of giant magnetoresistance (GMR); an exponential model is developed through calculus of variation. The model yields temperature coefficient α, that is strongly dependent on the system involved and plays the role of performance index. For instance, for Fe(1nm)/ITO(3nm) [1] and Co(3nm)/ITO(1.76nm) [2], ... corresponding predicted GMR of 6.46% and 2.62% at 1K. The model fits all experiment data considered.

TIMELIKE BIHARMONIC S-CURVES ACCORDING TO SABBAN FRAME IN (S1^2)H
In this paper, we study timelike biharmonic curves according to Sabban frame in the (S1^2)H. We characterize the timelike biharmonic curves in terms of their geodesic curvature. Finally, we find out their explicit parame...
ON THE REPRESENTATION OF A H1 (a, b) DISTRIBUTION THAT FULFILS u (a) = 0
We define the closed cone of increasing functions and represent each u as a sum of its projection on cone and the remaining part. We then define a scalar product and prove that the induced norm convergence implies the un...
EVOLUTION OF ALGORITHMS: A CASE STUDY OF THREE PRIME GENERATING SIEVES
In this paper, the algorithmic analysis is done with a view of inspecting the evolution of better and better algorithms. This has been with reference to three prime generating sieves. The Three sieves, starting with the...
NEW GENERALIZATIONS AND NEW APPROACHES FOR TWO IMO PROBLEMS
Success in problem solving requires effort. These are not routine exercises. They are problems whose solutions depend of trying something new (like approaches and generalization for IMO problems).This article presents so...

In this paper we shall try to transpose the conditions of the existence of propagators for kernel on *-semigroups, notion introduced by P. Masani [6]. We will start with a few additional observations concerning *-represe...
