Moulay Rchid Sidi Ammi, Delfim F. M. Torres • Discrete Dynamics in Nature and Society
(2013)
We obtain, by using the Leggett-Williams fixed point theorem, sufficient conditions that ensure the existence of at least three positive solutions to some p-Laplacian boundary value problems on time scales....

Liuna Qin, Changguo Xiao, Yinghui Zhang • Electronic Journal of Differential Equations
(2022)
We investigate optimal decay rates for higher-order spatial derivatives of solutions to the 3D compressible
Navier-Stokes-Poisson equations with external force. The main novelty of this article is twofold: First, we prove the first and seco...

Elahe Mohammadzadeh, Akbar Rezaei • Neutrosophic Sets and Systems
(2020)
In this paper, we introduce the notion of commutator of two elements in a specific NeutroGroup. Then we define the notion of a NeutroNilpotentGroup and we study some of their properties. Moreover, we show that the intersection of two Neutro...

针对注水开发的多层砂岩油藏分层动态分析难度大等问题，在常规井层开发指标计算基础上，结合动、静态劈分方法，综合考虑渗透率、孔隙度、地层系数、含水饱和度、位置系数、措施系数及注水量系数，提出了一种既可将油、水井作为统一整体，又可对小层、方向流动分量开发指标进行定量计算的体现渗流力学本质的方法。用大庆油田N2-O1井组的产液剖面资料进行验证。结果表明，所提方法的计算结果与测量结果吻合度较高，精度平均值达75.11%。用该方法计算开发指标，适用性强，能较真实地反映各小层、各方向的产液...
