Prior investments in fiber-optic backbones and cellular towers (for 3G) have had a significant impact on the viability of the latest wireless technologies (4G and 5G). It will be difficult for countries in the early stages of infrastructure development to make a rapid progress. However, richer countries will continue to invest in the fiber-optic ba...

Introduction. A brief overview of the properties and architecture of one of the components of the National Cloud of Open Science prototype – the cloud platform OpenStack is given. The list of software and hardware components of the OpenStack test cloud environment and the sequence of actions required for the deployment of both OpenStack itself and...

The organization of modern cloud services is based on theoretical results in logistics, operations research, supply chains, information transmission (transportation) networks, and on the practical achievements of the novel information and communication technologies. As all the inhabitants of the planet become regular users and at the same time crea...

The experience of the use of applied containerized biomedical software tools in cloud environment is summarized. The reproducibility of scientific computing in relation to modern technologies of scientific calculations is discussed. The main approaches to biomedical data preprocessing and integration in the framework of the intelligent analytical s...

The prototype of the intelligent analytical system was planned as
a regular software application. However, in the process of development and exploration,
it was realized the need to take into account the possibility of deploying the system
in different conditions, namely: in a cloud environment, a personal computer, and a powerful cluster.

The options of an intelligent analytical system for the analysis of heterogeneous clinical and biomedical data in order to improve the diagnosis of complex diseases are described. The software implementations of data processing and analysis have been developed − construction of classifiers, selection of informative features, processing of heterogen...

Introduction. The use of various cloud services is becoming an integral part of modern life. At the same time, the owners of such services usually are not going to inform users with the theoretical foundations of the deployment and provision of these services, as well as with issues of security. On the other hand, as the above literature review sho...

New approaches to estimating the coefficients of exact penalty functions for constrained optimization problems are considered. The results of computational experiments using simplified procedures for estimating coefficients in solving some classes of problems are presented. Such approaches are most relevant when applying methods of decomposition by...

We consider ways of transformation of convex optimization problems with constraints to equivalent problems with better computational properties. Sufficient attention is paid to use of conic approximations and conic prolongation of objective functions from admissible domain of optimization problem on the whole space of variables. The problem of conv...

The main purpose of this study is to propose Johansen's [6] methodology of linear cointegration analysis as a tool to measure the purchasing power of the Ukrainian mean total wages (MTW) within the period of November 1993 to December 2004 expressed in terms of prices of some basic food products or of the Consumer Price Index (CPI). Nineteen monthly...

A group of scientists, from Ukraine, the United Kingdom and Switzerland met at the 3rd International Congress on Industrial and Applied Mathematics (ICIAM95) Hamburg. They decided to pool their applied research efforts and experiences in the domain of mathematics, statistics and economics and to collaborate in empirical research on the subject of t...

The State Committee of Statistics of Ukraine (Derzhkomstat) has published several economic time series covering the last decade. In this paper a cointegration analysis of the Ukrainian time series, the Consumer Price Index (CPI), the mean monthly total wages of individuals, four price time series of basic foods: white bread, flour, semolina and mac...

Nonsmooth-optimization methods with space expansion are considered as applied to decomposition schemes realized in solving two-stage problems of stochastic programming in the SLP—IOR simulation systems.

This paper is a sequel to part I [Ukr. Mat. Zh.,47, No. 4, 443–452 (1995)]. By using the results of the first part, we obtain the initial terms of the asymptotic expansions of the bias and variance for the jackknife estimator of the variance of the error of observations in a nonlinear regressive model.

We obtain an asymptotic expansion of the functional of the jackknife method, which is used for the estimation of the variance of observational errors in a nonlinear regression model.

A cointegration analysis of the Ukrainian time series, the Consumer Price Index (CPI), the mean monthly total wages of individuals, four price time series of basic foods: white bread, flour, semolina and mac- aroni is proposed. The results give rise to existence of linear equilibrium relations for the couples wages-bread, wages-flour, wages-semolin...

The authors investigate the nonlinear regression model x j =g(j,θ)+ε j , j=1,⋯,n, θ∈Θ⊂ℝ q , q≥1, and present an asymptotic expansion of the distribution of the functional (L n (θ)-L n (θ ^ n ))/σ 2 , where L n (θ)=∑ j=1 n [x j -g(j,θ)] 2 , θ ^ n is the least square estimator of an unknown parameter θ∈Θ constructed from the observations x 1 ,⋯,x n ,...

The project builds up on the seminal mathematical analyses of PCMC, realised by Bertram Schefold (1976), L. L. Pasinetti (1977) and Kurz & Salvadori (1995). The background is the Theorem of Perron-Frobenius (1907, 1912). The aim is to present a modern presentaton of the material to get an operational level with a lot of calculated examples and applications up to Input-Output Tables.
