Reliability and Sensitivity Analysis of Harvesting Systems
Published In: GJSFR Part: F: Mathematics & Decision Volume: 14 Issue: 3
The objective of the present paper is to obtain the reliability of a harvesting system having three unit tractor (T), combine (C) and wagon (W) using supplementary variable technique. For successful operation of the system units T and C must be remain operative while when unit W fails system works partially. Two repairmen are involved in repairing of the system. One of the repairmen (the...

Homeotopy Groups of 2â€â€Dimensional Manifolds with One Boundary Component
Published In: GJSFR Part: F: Mathematics & Decision Volume: 14 Issue: 2
Let Y be a compact, connected 2â€â€dimensional manifold with boundary. The homeotopy group of Y, denoted H(Y), is defined to be the group of isotopy classes in the space of all homeomorphisms of Yonto Y. This group (also known as the mapping class group) has been studied for various manifolds (see, for example, [2] and [3 ]). It is also possible to consider “...

Effect of Variable Thermal Conductivity & Heat Source/Sink Near a Stagnation Point on a Linearly Stretching Sheet using HPM
Published In: GJSFR Part: F: Mathematics & Decision Volume: 14 Issue: 2
Aim of the paper is to investigate effects of variable thermal conductivity on flow of a viscous incompressible fluid in variable free stream near a stagnation point on a non-conducting stretching sheet. The equations of continuity, momentum and energy are transformed into ordinary differential equations and solved numerically using Similarity transformation and Homotopy Perturbation Met...

Some Statistical Properties of Exponentiated Weighted Weibull Distribution
Published In: GJSFR Part: F: Mathematics & Decision Volume: 14 Issue: 2
This article basically focused on some statistical properties of exponentiated-weighted weibull model which of course numerous authors have written one thing or the other on exponential weibull distribution and not on exponential weighted weibull. This model is established with a view to obtaining a model that is better than both weighted weibull and weibull distribution in terms of the ...

On the Relation between the Average Complexity of Trajectorries and the Complexity for Zn Action
Published In: GJSFR Part: F: Mathematics & Decision Volume: 14 Issue: 2
The complexity of finite object was introduced by A.Kolmogorov and V.Tihomirov in [2] and it was conjectured that for Z actions complexity coincides with topo- logical entropy, [2] ; [12] , [14] : In the present paper we introduce complexity for Zn actions and prove the Kolmogorov assertion for continuous actions of Zn: After, We will examine the relation between the average complexity o...

On the Valuation Credit Risk Via Reduced-Form Approach
Published In: GJSFR Part: F: Mathematics & Decision Volume: 14 Issue: 1
This paper presents the valuation of credit risk via reduced-form approach. Credit risk arises whenever a borrower is expecting to use future cash flows to pay a current debt. It is closely tied to the potential return of investment, the most notable being that the yields on bonds correlate strongly to their perceived credit risk. Credit risk embedded in a financial transaction, is the r...
