In recent years, the voltage quality in rural areas has aroused strong concern from the Stat Grid Corporation of China. This paper firstly analyze the over-voltage issues in the rural distribution networks from HUNAN province, and then proposes an output voltage control scheme of the Electric Spring (ES) to alleviate severe over-voltage problem in rural areas. The control objective of the ES is to...
This paper discusses the existing approaches of competitiveness' management of small and medium enterprises. Porter's diamond approach is analyzed. The way of building competitive advantages is discussed and case study about Indian companies is provided.
The author focuses on the issue of IT security for micro enterprises, specifically enterprises carrying out manual work considering German law and industrial requirements, with the aim of developing a self-implemented IT security assessment designed to identify threats and aid in increasing their security level. This is necessary because micro-enterprises contributing to the national economy have...
Data is becoming more and more valuable as technology advances. Through crowdsourcing organizations are able to collect large amounts of data at an effective rate with little cost. This paper proposes a crowdsourcing-based music playing system, where the next song to play is determined by the listening preferences of realtime online users. Unlike conventional radio play system, where songs are randomly...

This is caused by numerous inconsistencies between the responsibility in the framework of the Boards of Directors in the current corporate practice and the principles and recommendations of the Code of Corporate Governance...
Modern aspects of innovative management in transport system are based on strategic priorities in branch development and the project management approach. This approach can solve the problem of justification of the system of criteria for selecting technical and technological innovations and assessing their competitiveness. The result of this approach is determination of the balance level of the aggregate...
Euro-fuzzy instruments are implemented to help, but not replace, the managers in making decisions process. The up-to-date corporate management is based on the conceptual paradigm of governance and sustainable innovative growth. The machine learning is now a necessary tool for competitive companies' management: the business intelligence is a systemic approach to base the making decisions upon the use...
Free/Open Source Software developers come from a myriad of different backgrounds, and are driven to contribute to projects for a variety of different reasons, including compensation from corporations or foundations. Motivation can have a dramatic impact on how and what contribution an individual makes, as well as how tenacious they are. These contributions may align with the needs of the developer,...
In this study, we apply machine learning algorithms to predict technical failures that can be encountered in Oracle databases and related services. In order to train machine learning algorithms, data from log files are collected hourly from Oracle database systems and labeled with two classes; normal or abnormal. We use several data science approaches to preprocess and transform the input data from...
Companies of the engineer-to-order (ETO) business face various trends such as digitalization and globalization. These trends will radically impact our ways of engineering. The Engineering framework translates Dave Snowden's Cynefin framework [2] to the engineering world. Cynefin for Engineers allows structuring future ways of engineering and guiding ETO companies along their transformation of engineering...
The proposed model is intended to assessment of company's operation effectiveness, which is an important factor at investment decisions making. There are compared indicators of the growth rate, profitability and risk for shares placed on various stock exchanges with an assessment of the intrinsic value and management efficiency of company. The information received is useful for investors and company...
Many sentences create certain impressions on people. These impressions help the reader to have an insight about the sentence via some entities. In NLP, this process corresponds to Named Entity Recognition (NER). NLP algorithms can trace a lot of entities in the sentence like person, location, date, time or money. One of the major problems in these operations are confusions about whether the word denotes...
In a process collaboration, changes rarely confine themselves to a single company, but can spread over the network of partners, resulting in a whole process of negotiation. This paper employs techniques from the domains of multiple criteria decision making (MCDM) and group decision to deal with change negotiation in process collaborations. In particular, it utilizes multi-criteria reasoning to model...
In this article as an object of study is considered the transport system and mechanism of self-organization. The subject of research is social and economic power in the mechanism of self-organization of the transport system. The essence of our suggested scientific hypothesis is that transport system of a different level has to be regarded as a whole system. So it needs complex measurement instrument...
Encryption is often not sufficient to secure communication, since it does not hide that communication takes place or who is communicating with whom. Covert channels hide the very existence of communication enabling individuals to communicate secretly. Previous work proposed a covert channel hidden inside multi-player first person shooter online game traffic (FPSCC). FPSCC has a low bit rate, but it...
The emerging blockchain technologies have enabled development of crypto-currencies and autonomous smart contracts that can operate in decentralized and trustless settings. Distributed autonomous organizations can be implemented using smart contracts available on the Ethereum blockchain. In this paper, we propose a distributed autonomous software organization model and its Ethereum smart contract implementation...
The paper proposes company's investment activity simulation model; on its basis we investigate the behavior of company's fundamental value under different control parameters. The interaction of bank and corporate borrower's value growth is analyzed. On the basis of regularities obtained a set of decision principles has been formulated determining bank's decision on appropriateness of financial resources...
This paper examines the problem of choice investment strategies of firms in an oligopoly markets. We study the impact of investment strategies of companies on its financial performance and the efficiency of investment under demand uncertainty and competition in the market. A mathematical model describing the investment behavior of firms in an oligopoly markets presented. A solution of the problem...
Processes of technological transformations allow moving to a qualitatively new level of technology business. This makes it possible to speak about occurrence of so-called cognitive era. In these circumstances, new management technologies and approaches are developing, in particular, the cognitive technologies in management. The paper describes the application of cognitive technologies in business...
Estimating the difficulty of tasks is imperative for project planning, task assignment, and cost calculation. However, little is known about how and for what purpose software practitioners estimate task difficulty in their day-to-day work. In this paper, we interviewed 15 professionals to understand their needs and perceptions when estimating task difficulty. We find that practitioners do estimate...
