Information Security Risk Assessment Based on Information Entropy and Three-parameter Interval [PDF]

open access: yesJisuanji gongcheng, 2018
Information security risk assessment is a process that needs to deal with a lot of fuzzy information.In order to increase the accuracy of information processing,an information security risk assessment method based on three-parameter interval and ...

A novel approach based on preference-based index for interval bilevel linear programming problem

open access: yesJournal of Inequalities and Applications, 2017
This paper proposes a new methodology for solving the interval bilevel linear programming problem in which all coefficients of both objective functions and constraints are considered as interval numbers.

SMOOTH NUMBERS IN SHORT INTERVALS [PDF]

open access: yesInternational Journal of Number Theory, 2007
We show that for any ∊ > 0, there exists c > 0, such that for all x sufficiently large, there are x1/2 ( log x)- log 4 - o(1) integers [Formula: see text], all of whose prime factors are [Formula: see text].

Cubicity of Interval Graphs and the Claw Number [PDF]

open access: yesElectronic Notes in Discrete Mathematics, 2009
AbstractLet G(V, E) be a simple, undirected graph where V is the set of vertices and E is the set of edges. A b‐dimensional cube is a Cartesian product I1×I2×···×Ib, where each Ii is a closed interval of unit length on the real line. The cubicity of G, denoted by cub(G), is the minimum positive integer b such that the vertices in G can be mapped to ...

Interval Optimization-Based Unit Commitment for Deep Peak Regulation of Thermal Units

open access: yesEnergies, 2019
The deep peak regulation of thermal units is an important measure for coping with significant wind power penetration. In this paper, based on interval optimization, a novel multi-objective unit commitment method is proposed considering the deep peak ...

A note on the interval number of a graph

open access: yesDiscrete Mathematics, 1985
Three results on the interval number \(i(G)\) and d-dimensional interval number \(i_d(G)\) of a graph \(G\) with n vertices are presented. Theorem 1. The inequalities \(i(G)\geq n/4 lg_2 n\), \(i_d(G)\geq n/4d lg_2 n\) hold for almost every graph (i.e.

The Number of Intervals in the $m$-Tamari Lattices [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2012
An $m$-ballot path of size $n$ is a path on the square grid consisting of north and east steps, starting at $(0,0)$, ending at $(mn,n)$, and never going below the line $\{x=my\}$. The set of these paths can be equipped with a lattice structure, called the $m$-Tamari lattice and denoted by $\mathcal{T}_n^{(m)}$, which generalizes the usual Tamari ...

Health‐Related Social Needs in Children With Sickle Cell Disease Are Associated With Worse Health‐Related Quality of Life

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Children with sickle cell disease (SCD) face multiple acute and chronic medical complications that may impact their quality of life as reported by patients themselves. Health‐related social needs (HRSNs), such as food and housing insecurity, are common in people with SCD, but the association between HRSNs and patient‐reported ...

The Combined Effect of Obesity and Contraceptive Use on Pulmonary Embolism in Adolescent Females Residing in the United States

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Combined oral contraceptive (COC) use in obese adult women dramatically increases the relative risk of developing a pulmonary embolism (PE). The risk of a PE in obese adolescent females taking contraceptives is currently unknown. The purpose of this investigation was to determine the effect of body mass index (BMI) and contraceptive
