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 […]
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 […]
Koopman-based model predictive control of a nanometric positioning system
Nonlinear frictional disturbances limit the performances of high-precision mechatronics systems. Recently it was shown that nanometric positioning can be achieved only if these disturbances are identified, modelled and compensated for via suitable control approaches. A PID controller, complemented with feed-forward based on the Generalized Maxwell-slip model, allows hence to achieve nanometric positioning but its real-time […]
Near Real-time S-AIS: Recent Developments and Implementation Possibilities for Global Maritime Stakeholders
Adaptive Methods for Video Denoising Based on the ICI, FICI, and RICI Algorithms
In various applications, reducing noise from video sequence is of crucial importance. In this paper, we have presented performance analysis of the novel video denoising method based on the relative intersection of confidence intervals (RICI) rule, and compared it to the methods based on the intersection of confidence intervals (ICI) rule and the fast ICI […]
Sharing Economy and Workers’ Protection
The creation of the single market in the European Union is a continuing commitment. The European Commission published a series of documents in order to facilitate its accomplishment. In the Single Market Strategy and the Digital Single Market Strategy actions are focused on different levels. One of the targeted measures concerns creating additional opportunities for […]
New approach to flap-type wavemaker equation with wave breaking limit
The limitations of the classical wavemaker theory motivated the development of a new equation that can directly predict both regular and broken waves based on the flap-type wavemaker setup. This is achieved first by coupling a commonly accepted wave breaking formula with the linear wavemaker equation. Both these equations were then rewritten in terms of […]
