The objectives of the study were to demonstrate the suitability of methodology based on a text mining toolset for detecting trends in scientific papers and to find trends that were present in the field of project management during the research time span (2000–2019).

An approach based on text mining tools supported by expert analysis was adopted due to an extensive number of publications in the field of project management. The novelty of the approach lies in the proposed method of trends discovery instead of the commonly used trends predefinition. The use of computer support allowed the full texts of papers, and not only abstracts, to be analysed, which significantly increased the reliability of the achieved results. Overall, 3,544 papers from seven journals were analysed.

As a result, 43 trends were discovered including seven long-lasting, four declining, 17 emerging and 15 ephemeris trends. Trends were analysed in comparison with the results of previous studies and project management frameworks. New trends and potential gaps were discussed.

The results highlight the topics of research that gain popularity among researchers, and which are related to the current problems that arise in project management. Therefore, the results can help focus studies on the most important areas, as well as find new ones which are not so popular yet. The knowledge of current trends is also important for those project managers who seek to improve the efficiency of their work.

The purpose of this paper is to compare the accuracy of tracking the amplitude and frequency changes of non‐stationary electric signals.

Short‐time fourier transform (STFT) and S‐transform algorithms were applied to analyze non‐stationary signals originating from switching of capacitor banks in a power system.

The S‐transform showed possibilities of sharp localization of the basic component, and allowed improvement of tracking dynamism the transient components in comparison to STFT.

S‐transform is a better tool for the analysis of non‐stationary waveforms in power systems and its properties can be used for diagnostic and power quality applications.

The dynamic tracking of the changes in time and frequency of real‐like signals originating from a power system are investigated in this paper.

Gives introductory remarks about chapter 1 of this group of 31 papers, from ISEF 1999 Proceedings, in the methodologies for field analysis, in the electromagnetic community. Observes that computer package implementation theory contributes to clarification. Discusses the areas covered by some of the papers ‐ such as artificial intelligence using fuzzy logic. Includes applications such as permanent magnets and looks at eddy current problems. States the finite element method is currently the most popular method used for field computation. Closes by pointing out the amalgam of topics.

The purpose of the paper is to determine the future role of virtual currencies. This paper indicates their pros and cons as alternatives to “real” money and explains their appearance as the reflection of the present trends. It also presents the possible scenarios of their development.

The paper is based on the former foresight research results and literature review. It highlights the main trends in contemporary economy and their impact on financial services. The Bitcoin case is the starting point for the virtual currencies’ market analysis and construction of possible market changes scenarios.

Virtual currency schemes are the reflection of present trends. They are just ahead of our times but may become a common means of payment, changing the way of providing financial services, eliminating intermediaries and marginalizing the role of financial institutions.

The multiplicity of virtual currencies and ceaseless introduction of innovations impede the presentation of the complete market picture. The lack of reliable statistical data makes the estimation of the market growth difficult.

This paper indicates influence of technology development, virtualization and networking on payment systems’ functioning.

This paper shows the impact of environmental changes on consumers’ acceptance of virtual currencies.

The virtual currency as a payment system is quite new and still a marginalized phenomenon. Nevertheless, the pace of virtual currency market growth after its recent introduction and appearance of Bitcoin successors seems to be the signs of future changes in financial service sector.
