The aim of this study was to investigate the application of classical machine learning algorithms for the detection of rectal tumors on computed tomography (CT) images of patients following neoadjuvant chemoradiotherapy. The study included 138 patients, of whom 136 had a confirmed tumor, while two subjects with a healthy rectum were included to bal...

Within the ATMOLCOL project, experimental investigations of electron–molecule collisions increasingly require theoretical input capable of clarifying the molecular mechanisms that lead to fragmentation. The work presented here contributes to this effort through the development of a computational model aimed at simulating fragmentation of mole...

This paper presents a novel and computationally efficient algorithm for improving the accuracy of phasor estimation in the presence of a decaying DC (DDC) component in fault current signals of transmission lines. In digital protective relays, the Discrete Fourier Transform (DFT) is widely employed for estimating the fundamental frequency phasor. Ho...

The honey market in Bosnia and Herzegovina faces significant challenges regarding product authenticity and quality control. The lack of a well-regulated inspection system, combined with limited consumer awareness, creates favorable conditions for the distribution of adulterated products. This study examined 25 samples in total: 10 honey samples wit...

This paper analyzes a model of sustainable organic waste management through the utilization of rabbit manure via vermicomposting. Rabbit manure, consisting of solid and liquid excreta combined with bedding materials (straw, sawdust), is not directly applied to agroecosystems but is biologically transformed using California red worms (Eisenia fetida...

Ionic liquids represent a highly tunable class of compounds whose physicochemical and biological properties can be modified through rational selection of cations and anions. In this study, three imidazolium-based ionic liquids containing oxychlorine anions were synthesized and characterized: 1-butyl-3-methylimidazolium chlorite, chlorate and perchl...

Dreams occupy a central place in classical psychoanalytic theories, where they are seen as meaningful expressions of unconscious psychic processes. In the Freudian and Jungian theoretical tradition, dreams are viewed as an important source of insight into the inner psychic dynamics of an individual, whereby their interpretation and integration are ...

The paper presents an insight into the mathematical basis of fuzzy linguistic modeling and discusses the sensitivity of fuzzy rule-based systems with respect to membership function parameters, rule structure, and inference mechanisms. Examples with different inference models are analyzed and compared in order to illustrate their influence on the be...

The subject of this paper is a combined integer-valued autoregressive time series model with both positive and negative values, constructed by means of a new thinning operator. The proposed model can be regarded as a precursor of random environment integer-valued INAR models with state space on the entire set , providing a flexible framework for mo...
