Dinatural transformations, which generalise the ubiquitous natural transformations to the case where the domain and codomain functors are of mixed variance, fail to compose in general; this has been known since they were...
This study provides forecasts of tourist arrivals for the most popular destinations in Greece, using the ARIMA and Holt-Winters (H-W) forecasting models. The Holt-Winters (H-W) approach forecasts increase in tourism, while the...
The use of local data journalism has the power to fundamentally change local news. Local journalists can find vital insights, spot trends, and shed light on significant issues that have an impact on their communities by...

The paper explains the need for a standard way of defining modelling constructs from different enterprise modelling languages and proposes a template for defining enterprise modelling constructs in a way that facilitates...

Safety is a fundamental concern in modern society, and security is a precondition for safety. Ensuring safety and security of complex integrated systems requires a coordinated approach that involve different stakeholder groups...
There are concerns amongst researchers and the general public that social media platforms threaten democratic values. Social media corporations and their engineers have responded to these concerns with various design solutions....
Text entry remains key to many tasks on touchscreen smartphones and is an important factor in the usability of such devices. The known problems of text entry can be particularly acute for older adults due to physical and...
In the guise of artificial neural networks (ANNs), genetic/evolutionary computation algorithms (GAs/ECAs), fuzzy logic (FL) inference systems (FLIS) and their variants as well as combinations, the computational intelligence (CI)...
Recently, a technical draft of the international standard ISO/DIS 30500 for non-sewered sanitation systems has been developed (publication expected for 2018). Its innovative feature is the inclusion of sustainable aspects. This...
This article provides a listing of known copies of the first two folio editions of Andreas Vesalius’ $\textit{De humani corporis fabrica}$ (1543 and 1555), revising earlier estimates. It shows that the $\textit{Fabrica}$...
Structural flexibility in a petroleum pitch-derived carbon material has been indirectly evaluated using X-ray diffraction (XRD), immersion calorimetry and inelastic neutron scattering (INS) measurements. Exposure of the carbon...
In this paper, we integrate fertility and educational choices into a scale-invariant model of directed technological change with non-renewable natural resources, in order to reveal the interaction between population dynamics...
We propose an overlapping generations model with three social classes to investigate the effects of higher education on the evolution of inequality. Initially, no social class invests in higher education and inequality is driven...
Response to: 'Prevention of infections in patients with antineutrophil cytoplasm antibody-associated vasculitis: Potential role of hydroxychloroquine' by Novikov et al
We develop a model of monetary policy implementation in which banks bid for liquidity provided by the central bank in fixed rate auctions, considering liquidity injections and extractions as well as the impact of a subsequent...
