Reverse degree distance of unicyclic graphs
Degree Distance Reverse degree distance Diameter Unicyclic graph Pendant vertices Maximum degree
2011/9/1
Abstract: The reverse degree distance is a connected graph invariant closely related to the degree distance proposed in mathematical chemistry. We determine the unicyclic graphs of given girth, number...
Optimal control of reverse logistics model with logistic demand and return rates
Optimal control reverse logistics model logistic demand return rates
2010/9/27
Pontryagin minimum principle (PMP) is applied in this paper to find the optimal control of the reverse logistics model of a production inventory system with deteriorating items. The total cost of the ...
Linearized inverse scattering based on seismic Reverse Time Migration
Linearized inverse seismic Reverse Time Migration
2011/2/23
In this paper we study the linearized inverse problem associated with imaging of re ection seismic data.
Higher-order derivatives of the QR and of the real symmetric eigenvalue decomposition in forward and reverse mode algorithmic differentiation
univariate Taylor polynomial arithmetic higher-order derivatives QR decomposition real symmetric eigenvalue decomposition
2010/12/15
We address the task of higher-order derivative evaluation of computer programs that contain QR
decompositions and real symmetric eigenvalue decompositions. The approach is a combination of univariate...
Reverse mathematics and equivalents of the axiom of choice
Reverse mathematics equivalents axiom of choice
2010/12/8
We study the reverse mathematics of countable analogues of several maximality principles that are equivalent to the axiom of choice in set theory.
Reverse Engineering Financial Markets with Majority and Minority Games using Genetic Algorithms
agent-based models Genetic Algorithms
2010/4/27
Using virtual stock markets with artificial interacting software investors, aka agent-based models (ABMs), we present a method to reverse engineer real-world financial time series. We model financial ...
The Refinement and Reverse of a Geometric Inequality
Geometric inequality Best constant Triangle
2010/4/16
In this paper, we give a refinement and a reverse of a geometric inequality in a triangle posed by Jiang [2] by making use of the equivalent form of a fundamental inequality [6] and classic analysis.
The Reverse and Generalized Poincaré Inequality
equivalent norms unbounded operators Poincar´ e inequality Banach space embeddings Hilbert spaces
2009/6/16
In this paper we show that, by the use of an equivalent norm, one can make unbounded
linear operators exhibit one of the most important properties of bounded operators
without using the graph norm. ...
The Reverse Ultra Log-Concavity of the Boros-Moll Polynomials
log-concavity reverse ultra log-concavity Boros-Moll polynomials
2014/6/3
We prove the reverse ultra log-concavity of the Boros-Moll polynomials. We further establish an inequality which implies the log-concavity of the sequence {i!di(m)} for any m ≥ 2, where di(m) are the ...
A review of reverse logistics
reverse logistics recovery options reuse remanufacturing recycling
2009/1/8
The impact of economics and environmental statutes has caused a new set of
generic issues in reverse logistics. The other challenges in this field have been
caused by the rapid development of e-comm...

2010/9/10
New generalizations of Hardy-Hilbert's integral inequality and its reverse via new methods are established.
Further Reverse Results for Jensen's Discrete Inequality and Applications in Information Theory
Convex functions Jensen's Inequality Entropy Mappings
2008/7/1
Some new inequalities which counterpart Jensen's discrete inequality and improve the recent results from [20] and [22] are given. A related result for generalized means is established. Applications in...
