At present, the scattered and closed steel logistics resource should be integrated. Reasonable benefit allocation mechanism is the prerequisite for steel logistics resources integration. Based on previous studies on steel logistics resource integration, this paper proposes an important problem in steel logistics resources integration: benefit distribution. First, this paper gives the classifica...

We construct an hyperinterpolation formula of degree n in the three-dimensional cube, by using the numerical cubature formula for the product Chebyshev measure given by the product of a (near) minimal formula in the square with Gauss-Chebyshev-Lobatto quadrature. The underlying function is sampled at N ∼ n/2 points, whereas the hyperinterpolation polynomial is determined by its (n + 1)(n + 2)(n...

Algorithms for estimating the integral over hyper-rectangular regions are discussed. Solving this problem in high dimensions is usually considered a domain of Monte Carlo and quasi-Monte Carlo methods, because their power degrades little with increasing dimension. These algorithms are compared to integration routines based on interpolatory cubature rules, which are usually only used in low dime...

SCADA systems are widely spread in automation, monitoring and control systems for industrial processes. These systems are used to develop the factories of the future. Currently, the most SCADA systems allow data sharing only within a local network. With the development of the Internet of Things concept, it was started to be used in the systems for the factories of the future. One of the most po...

Zipf’s law appears in many application areas but does not have a closed form expression, which may make its use cumbersome. Since it coincides with the truncated version of the Zeta distribution, in this paper we propose three approximate closed form expressions for the truncated Zeta distribution, which may be employed for Zipf’s law as well. The three approximations are based on the replaceme...

A new mode matching method is developed for acoustic modes in axially sectioned lined ducts with parallel, but otherwise arbitrary mean flow. The method is evaluated in detail for a circularly symmetric configuration (where the mean flow only depends on the radial coordinate), with so-called Pridmore-Brown modes, satisfying the radial Pridmore-Brown equation. Classically, the matching of the mo...

Executive Summary The objective of Reservoir Monitoring Consortium (RMC) is to develop new methods for dynamic reservoir monitoring. We will carry out a number of focused applied research projects in reservoir monitoring that are directly pertinent to the current and future needs of our industry sponsors. We will develop specific workflows for different types of reservoirs. This will include th...
