The paper is dedicated to the development of modern education technologies in distinct regions on the example of Yamalo-Nenets Autonomous Okrug. The author showed that students in this region are underprivileged besides the level of average income and salary because of a lack of ordinary higher education programs and low Internet quality. The development of e-learning opportunities can increase quality...
Online professional social networks such as LinkedIn have enhanced the ability of job seekers to discover and assess career opportunities, and the ability of job providers to discover and assess potential candidates. For most job seekers, salary (or broadly compensation) is a crucial consideration in choosing a new job. At the same time, job seekers face challenges in learning the compensation associated...
Spreadsheets often contain faults that are difficult to localize. Spectrum-based Fault Localization (SFL) assists users in the fault localization process by ranking cells by their suspiciousness to contain a fault. Since the ranking of the basic SFL approach is often imprecise, we propose three techniques to improve it, i.e., dynamic cones, grouping, and tie-breaking. We evaluate these techniques...
Passengers and freight mobility in urban areas represents an increasingly relevant component of modern city life. On one side, it fosters economic growth, but, on the other, it also generates high social costs. Congestion and pollution are two problems policy-makers want to curb adopting appropriate measures. The pervasive use of information and communication technology will contribute to the fuller...
Compared to living alone, sharing housing with others is usually much cheaper. Meanwhile, share-housing life would exert mammoth impact on people's social activity and self development by help them save house rental cost and improve their life quality. This paper proposes an allocation information system for share-housing management, which takes into account preference on roommates' living habits,...
A Distribution System Operator (DSO) might consider a capacity contract as a planning alternative to defer grid investments. A Virtual Power Plant (VPP) might be able to provide such capacity and change its production as requested by the DSO. This article presents an assessment of the impact of this type of distribution capacity contract (DCC) on VPP's remuneration. This assessment is done by comparing...
Electricity market design varies across countries throughout Europe. Thereby the provision and remuneration of flexibility always takes place in short-term market segments. Taking into consideration the fundamental changes of the power system, this paper discusses options for the future short-term market design. We develop a conceptual basis for a possible integration of currently separated short-term...
The aim of this paper is to study the implications of the decision of the French regulator to join the FCR Cooperation, a common platform for cross-border procurement of primary reserve. Two aspects will be analyzed: 1) cost of procurement and increase of social welfare by cross-border procurement and 2) implications for entry of new entrants like aggregators of Electric Vehicles. Our results are...
The first part of the article presents the assumptions of the capacity market in Poland that was recently presented by the Ministry of Economy. The mechanism is based on the centralized capacity market solution already implemented in Great Britain, however, introduces novel solutions such as separate auctions for new and existing power units. In the second part, we described the modifications that...
The increase of distributed energy resources in energy systems and current legislation concerning the participation in energy markets, is causing a high wasted potential of energy supply and flexibility services. In this paper, it is proposed a methodology for the management and integration of distributed energy resources in energy systems and markets, through the application of an aggregator. Also,...
The analysis of the human migration process has been studied in various fields of science. This work, focuses on migration indicators proposed by the International Migration Policy, with the aim of identifying the most important indicator from the point of view of data mining. This study identifies migrant stock as the most important factor related to the values obtained by the F1Score and the ROC...
Using the case of organization H, this paper studies the current development of scientific and technological talents. Based on recent research in this filed, we develop an index system of incentive factors, including material incentive, implicit incentive, support incentive and growth incentive. Then we survey 244 scientific and technological talents and use factor analysis method to study the valid...
The aim of this paper is to investigate the relationship between labour productivity and labour remuneration among agricultural and non-agricultural sectors in selected EU countries. The issue under investigation pertains to the question of whether remunerations for labour and their rate of growth are attributable to changes in labour productivity. The problem is analyzed via static and dynamic approaches...
One of our goals is to formalize an equivalence class(FEC) of the fuzzy relational database(FRDB). FRDB, an extension of RDB using a soft computing technique, fuzzy theory. Using our relational formulas of relational calculus, we can denote its properties by simple and correct formulas. Also, we can prove its properties formally using relational calculus. There are many applications of FRDB such as...
Offshoring software development activities to a remote site in another country continues to be one of the key strategies to save development cost. However, the assumed economic benefits of offshoring are often questionable, due to a large number of hidden costs and too simple cost calculations. This study is a continuation of our work on calculating the true hourly cost that includes the extra direct...
Crowdsourcing coordinates a large group of workers online to do self-contained small tasks that are published by job requesters on a crowdsourcing platform. Many papers propose incentive strategies to motivate workers to participate in crowdsourcing. In this paper, we shift the focus from the workers to the job requesters by addressing two of their issues: how to design a good payment scheme to maximize...
The concept of a team collective intelligence is based on the series of focused expert interviews with enterprise managers and entrepreneurs. The theoretical analysis helped to formulate the main positions of the concept of collective intelligence, compared with collected intelligence as a simplified sum of the knowledge, visions, perception and understandings of the team members. The team's collective...
Firstly, the definitions of software combination coverage test and several combinatorial coverage algorithms are briefly introduced, and the advantages and defects of the combinatorial testing methods are compared. Then the concepts of input parameters constraints are descripted in detail. At last, a method of reducing the combinatorial test case sets based on parameter constraint relations is presented,...
One of the fundamental applications for a practically useful system of money is remuneration. Information pertaining to the amount of compensation awarded to different individuals is often considered sensitive, commanding a certain degree of privacy. As Bitcoin and similarly designed cryptocurrencies evolve into a recognized medium of exchange for larger swaths of the world economy, an increasing...
Privacy preserving of multi-sensitive attributes datasets (MSA-Datasets) has received increasing attention because of its huge social and economic benefits. In this paper, we introduce a novel and general privacy framework called Transparent Link. The Transparent Link framework can be used to anonymize MSA-Datasets by designing an algorithm based on probabilistic graphical model, which is referred...
