Random peptide libraries that cover large search spaces are often used for the discovery of new binders, even when the target is unknown. To ensure an accurate population representation, there is a tendency to use large libraries. However, parameters such as the synthesis scale, the number of library members, the sequence deconvolution and peptide structure […]

Local-Entropy Based Approach for X-Ray Image Segmentation and Fracture Detection
The paper proposes a segmentation and classification technique for fracture detection in X-ray images. This novel rotation-invariant method introduces the concept of local entropy for de-noising and removing tissue from the analysed X-ray images, followed by an improved procedure for image segmentation and the detection of regions of interest. The proposed local Shannon entropy was […]

Digital transformation of society: Legal aspects
Digitalisation transforms and accelerates not only the ways of doing business, but also the ways of thinking. Unprecedented interconnectedness and access in the cyberspace, where everything is available at the touch of a finger, give rise to many issues concerning the transfer and impact of new technologies from the digital world on social relations in […]
Support Vector Machine State Estimation
The power system state estimator based on the support vector machine (SVM) and the weighted least squares (WLS) method is presented in the paper. The WLS provides state estimations necessary for creating SVM model which is then used for state estimation. The developed algorithm was tested on the IEEE systems, and the performance indicators were […]
Development of machine-learning-based techniques for illness and injury detection in medical images
Clinical decision-support systems are often built by manually gathering, formalising and implementing specialist knowledge. Therefore, they are limited by existing human knowledge concerning modelling clinical conditions, diagnosis and therapy, and can be inaccurate because of variations and complexity inherent to medical data. In order to circumvent these limitations, following an obvious growth of publicly available […]
QR Code Alternative – Increased Storage Capacity for Offline Transfer
Research on QR code alternatives with goal of increasing code storage capacity. The project is conducted at the Faculty of Engineering, University of Rijeka (www.riteh.uniri.hr).
The Influence of Feature Representation of Text on the Performance of Document Classification
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 at the Johannes Kepler University of Linz, Austria
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 […]
