The book contains new models of bibliometric analysis based on centrality measures in network analysis, pattern analysis and stability analysis. A distinctive feature of these centrality measures is that they account for the parameters of vertices and group influence of vertices to a vertex. This reveals specific groups of publications, authors, terms, journals and affiliations ...

In this paper, we introduce a refined and rigorous methodological framework for the validation and quality assessment of pattern analysis outcomes. Our approach synergistically integrates a formal algorithmic model with novel conceptual constructs - specifically, the notions of the empty pattern and pattern complexity. A comprehensive array of metric approaches is employed to evaluate pattern analysis ...

An agglomerative pattern analysis algorithm is presented that groups objects using ordinal-invariant pattern clustering, with the goal of maximizing the coefficient of determination. Key stages are described: constructing initial pattern pattern by grouping objects according to permutations of feature values; computing centroids and variances; and defining a merge criterion based on the maximal increase in ...

We propose a novel method for rapid pattern analysis of high-dimensional numerical data, termed tunnel clustering. The main advantages of the method are its relatively low computational complexity, endogenous determination of cluster composition and number, and a high degree of interpretability of final results. We present descriptions of three different variations: one with fixed hyperparameters, ...

A new method for searching patterns in data using interval estimates is proposed. The computational complexity, algorithmic implementation, and some properties that allow the method to be applied to high-dimensional data are described, including the characteristics of ordering the studied indicators in groups obtained from the analysis, the unambiguous definition of such groups, and their ...

Abstract: COVID-19 pandemic (2020-2022) and following sanction crisis (since February 2022) provided a new background for tourism cluster activity. The background mentioned has formed a basis for new set of tourism cluster support measures. The problem mentioned tends to be actual for Perm krai, which has launched a discussion on region tourism potential support in ...

We present methods for finding patterns using sorting algorithms. Two modifications of diffusion-invariant pattern clustering are proposed, which allow finding structurally similar objects under study. The proposed modifications allow you to reduce the time spent on searching for templates, which allows you to work with big datasets. It assumes endogenous quantification and distribution of income ...

The purpose of the article is to consider innovation development in Russian regions and suggest certain opportunities for BRICS member countries. Our findings implicate that for many regions in Russia, where innovation areas are absent, taking part in interregional cooperation may be a good chance to enforce their innovative performance. Our results also demonstrate that ...

Целью работы является исследование методов идентификации отдельно взятых фрагментов компьютерных файлов и разработка процедуры восстановления фрагментированных файлов формата JPEG. Разработанный метод позволяет определить принадлежность фрагмента файла к указанному формату и тем самым выявить лишние (чужеродные) фрагменты в файле. Данный метод может применяться, в том числе, и в задачах восстановления файлов данного формата. Необходимость восстановления данных ...

New cobalt‐iron chalcogenide clusters C5HMe4Co(CO)E2Fe2(CO)6 (E = Se, Te) were prepared and characterized by IR and NMR spectroscopy; their structures were determined by single‐crystal XRD. Catalysts consisting of nanoparticles of bimetallic chalcogenides of cobalt and iron deposited on highly dispersed carbon black Vulcan XC‐72 were made from the synthesized clusters. Structural characteristics of these catalysts were ...

Несмотря на популярность темы кластеров в мировой научной литературе, специфика в этом вопросе стран с бывшей плановой экономикой не является до конца раскрытой. В частности, мало эмпирических исследований кластеров России. Указанная специфика выражается в том, что предприятия в данных странах либо являются наследниками плановой системы, либо слишком молодыми в сравнении с аналогичными компаниями стран с ...
