In this paper we perform a comparative analysis of three models for a feature representation of text documents in the context of document classification. In particular, we consider the most often used family of bag-of-words models, the recently proposed continuous space models word2vec and doc2vec, and the model based on the representation of text documents […]

Invited lecture on “Computer-Aided Signal Analysis: Methods and Applications” by Assis. Prof. Jonatan Lerga, PhD, at the Johannes Kepler University (JKU) of Linz, Institute of Signal Processing, Austria, was held on the 28th of February and 1st of March, 2019.
ECDIS transitional period completion: Analyses, observations and findings
During the past three decades, the Electronic Chart Display and Information System (ECDIS) evolved from its initial purpose to a complex navigation support tool. The transition from paper to electronic charts represents a substantial step in navigation, contributing to the reduction of the navigator’s workload, ease of execution of navigational tasks and integrated information and […]
Customizing morphology, size, and response kinetics of matrix metalloproteinase-responsive nanostructures by systematic peptide design
Overexpression and activation of matrix metalloproteinase-9 (MMP-9) is associated with multiple diseases and can serve as a stimulus to activate nanomaterials for sensing and controlled release. In order to achieve autonomous therapeutics with improved space-time targeting capabilities, several features need to be considered beyond the introduction of an enzyme-cleavable linker into a nanostructure. We introduce […]
Data Stream Mining for Smart Cold Chain Management (SmaCC)
As a result of declining natural resources and growing populations, perishable food chains face the challenge of increasing food handling efficiency and minimizing post-harvest damage. The project proposes an SmaCC system based on the application of in-depth data flow analysis procedures for the analysis of sensory stream data. The data is generated by the latest […]
Computer-Aided Digital Analysis And Classification of Signals
Various natural phenomena are described by stochastic signals, the analysis of which requires utilizing advanced, computationally demanding algorithms (such as simultaneous processing of signals in time and frequency domain using quadratic time-frequency distributions). Besides being stochastic, these signals are usually non-stationary and multi-componential. Hence, to process them, it is necessary to develop adaptive algorithms for […]

“Old Economy“ Restrictions in the Digital Market for Services
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 […]
