In many practical experiments, both the level combinations of factors and the addition orders will affect the responses. However, virtually no construction methods have been provided for such experime...
Extremal Distribution for the Discrete 5-convex Stochastic Ordering and Applications
s-convex order moment space extremal distribution branching process Lundberg's coeffici
2011/11/9
In this paper, motivated by the idea from Courtois and Denuit et al.(2006), we derive extremal distribution for the discrete 5-convex stochastic ordering. As applications,We improve lower and upper bo...
An effective method to compute closure ordering for nilpotent orbits of $θ$-representations
compute closure nilpotent orbits of $θ$-representations Algebraic Geometry
2011/8/31
Abstract: We develop an algorithm for computing the closure of a given nilpotent $G_0$-orbit in $\g_1$, where $\g_1$ and $G_0$ are coming from a $\Z$ or a $\Z/m\Z$-grading $\g= \bigoplus \g_i$ of a si...
Counterexamples to Ferromagnetic Ordering of Energy Levels
Heisenberg model quantum spin systems simple exclusion process ordering of energy levels Aldous ordering spectral gap
2011/8/26
Abstract: The Heisenberg ferromagnet has symmetry group ${\rm SU}(2)$. The property known as ferromagnetic ordering of energy levels (FOEL) states that the minimum energy eigenvalue among eigenvectors...
Ordering of small particles in one-dimensional coherent structures by time-periodic flows
time-periodic flows small particles Ordering one-dimensional coherent structures
2011/7/7
Small particles transported by a fluid medium do not necessarily have to follow the flow. We show that for a wide class of time-periodic incompressible flows inertial particles have a tendency to spon...

Curve Reconstruction Riemannian Manifolds Ordering Motion Frames
2011/3/3
In this article we extend the computational geometric curve reconstruction approach to curves in Riemannian manifolds.We prove that the minimal spanning tree, given a sufficiently dense sample set of ...
Supply chain model for the retailer's ordering policy under two levels of delay payments in fuzzy environment
Fuzzy numbers Function Principle
2010/9/21
In this paper we discuss the retailer’s ordering policy under two levels of delay payments by considering the selling price per item to be higher than the purchasing cost per item. The demand and sell...
Retailer's pricing and ordering strategy for Weibull distribution deterioration under trade credit in declining market
Finance Weibull deterioration trade credit
2010/9/21
In this research article, an ordering and pricing policy is formulated for a retailer when the supplier offers a delay in payments to settle the accounts against the retailer’s due. The problem is to ...
Ordering subsets of (partially) ordered sets: Representation theorems
partial orders ordering subsets of a poset
2010/9/20
In many practical situations, we have a (partially) ordered set V of different values. For example, we may have the set of all possible values of temperature, or the set of all possible degrees of con...
Ordering policy for Weibull deteriorating items for quadratic demand with permissible delay in payments
Weibull deterioration trade credit Quadratic demand
2010/9/26
This paper deals with the development of an inventory model for Weibull deteriorating items in quadratic demand market when delay in payments is allowed to the retailer to settle the account against t...
On Random Field Induced Ordering in the Classical XY Model
Random Field Induced Ordering Classical XY Model
2010/12/13
Consider the classical XY model in a weak random external field pointing along the Y axis with strength . We study the behavior of this model as the range of the interaction is varied.
We prove that...
Ritt-Wu's Characteristic Set Method For Ordinary Di®erence Polynomial Systems With Arbitrary Ordering
dierence polynomial ascending chain characteristic set Ritt-Wu's zero decomposition theorem
2013/9/9
In this paper, a new Ritt-Wu's characteristic set method for ordinary di®erence systems is proposed, which is valid for any admissible ordering. New deˉnition for irreducible chains and new zero ...

The Laplace order and ordering of reversed residual life
Laplace transform order Laplace transform order of reversed residual life
2010/9/15
The purpose of this paper is to study new stochastic comparisons based on the Laplace transform order of reversed residual life. Some basic properties of the new order are given. We also provide sever...
A new ordering method is proposed for automated theorem proving of differential geometry,by which Cartan's moving frame method can be combined with Wu's elimination principle.
