Freedom to provide services is one of the cornerstones of the EU internal market. Facilitated by the digital technologies, new and innovative service markets are emerging. However, innovations often bump into existing obstacles. Whether constrained by inadequate regulatory environment, or opposition from existing service providers in the market, the fact remains that ‘old economy’ is […]

Design and Implementation of Anonymized Social Network-based Mobile Game System for Learning Mathematics
Group work and student collaboration during problem solving sessions are teaching methods which positively affect learning outcomes and socialisation. It is extremely complex to find a way of applying these methods to make them appropriate for and interesting to the new digital generation of students. This paper proposes a model which enables social network collaboration […]
Adaptive State Estimator With Intersection of Confidence Intervals Based Preprocessing
The paper presents an effective solution for improving power system state estimation performance by applying the intersection of confidence intervals (ICI) algorithm, a state-of-the-art adaptive signal processing technique used in signal denoising. Since many power utilities worldwide still run state estimators based on the weighed least squares (WLS) algorithm using supervisory control and data acquisition […]

Analytical implementation of Roe solver for two-layer shallow water equations with accurate treatment for loss of hyperbolicity
A new implementation of the Roe scheme for solving two-layer shallow-water equations is presented in this paper. The proposed A-Roe scheme is based on the analytical solution to the characteristic quartic of the flux matrix, which is an efficient alternative to a numerical eigensolver. Additionally, an accurate method for maintaining the hyperbolic character of the governing system […]
A Network for Gravitational Waves, Geophysics and Machine Learning
The breakthrough discovery of gravitational waves on September 14, 2015 was made possible through synergy of techniques drawing from expertise in physics, mathematics, information science and computing. At present, there is a rapidly growing interest in Machine Learning (ML), Deep Learning (DL), classification problems, data mining and visualization and, in general, in the development of […]
Making a Living in the “Gig” Economy: Last Resort or a Reliable Alternative
Modern work arrangements in the collaborative or ‘gig’ economy challenge and redefine traditional work patterns. Extensive scholarly writings in the last years have been dedicated to revealing the true nature and implications of such work, and this topic is a matter of heated debates. However, empirical research on the prevalence of ‘gig’ work is still […]
