The paper deals with the problematics of the dense volume datasets representation, in which voxels are formed as multi-bit scalar values, and is oriented to the use of hierarchical data structures, not only as the medium for encoding and storing of volume datasets, but also for their lossless compression. The main contribution of the paper is in the design of the hierarchical data structure, that allows carving out of subtrees, that are homogenously filled not only by the symbol 0 or symbol 1, but any binary representation of voxel value from defined set of values. Designed data structure provides the possibility of fixed-length and also variable-length (Huffman) encoding of voxel values in leaf node level of the data structure and also in the non-leaf nodes. Results of tests, performed on medical volume datasets that were obtained by various non-invasive imaging techniques, including Computed Tomography and Magnetic Resonance Imaging, along with conclusions that were made, based on the test results, take place in the second part of the paper.

The aim of the pilot study was to determine the mechanical load using a glass-coated microwire on 3 experimental samples at different positions of the microwire (vertical, horizontal, diagonal position) for possible application in the field of implantology. The production of experimental samples was created by additive technology from a flexible material. The mechanical load ranged from F = 40 N to F = 50 N and was measured by a force sensor. A frequency generator (GW instek GFG-3015) and an oscilloscope (Tektronix TDS 2001C) were used to generate and detect the signal. The switching field of the microwire was excited and sensed through 0.4 mm diameter (excitation coil) and 0.056 mm (sense coil) coils. The results of the study indicate a relationship between the switching field of the microwire and the mechanical load, and it was shown that in experimental samples 1 and 2 a decrease in the switching field of the microwire was detected as a result of poor fixation or bending of the microwire. Experimental sample 3 showed the best switching field values. However, by solving the fixation of the microwire into the implemented object, this type of microsensor makes a suitable candidate in the field of implantology.

Lead times are key to good market positioning of providers of automated solutions based on a programmable logic controller (PLC). Testing control software against a digital twin (DT) of the process, any programming errors that may have incurred are detected before commissioning, which reduces project duration. This work raises the possibility of reducing that probability of error when programming discrete event dynamic systems (DEDS), by implementing a Petri net (PN) managing algorithm. A framework is presented which combines the use of this algorithm, by means of pre-incidence and post-incidence matrices and initial marking vector of a net, with code validation through emulation. A use case is brought forward in which the control program of a sequential process with parallel operations is implemented, with both virtual (VC) and real commissioning.

This paper presents the application of edit distance functions for the measuring of morphological ambiguity and similarity between the natural languages. We propose sequence and tree edit distance functions for the Universal dependencies framework, which compare both morphological and syntactical annotations of the words in the sentences. The experiments were performed with the Slovak as a reference language and set of Slavic languages for comparison.

Heat treatment process represents an important part of metal-ceramic dental prostheses production process. The presented paper deals with the influence of heat treatment on the geometry of dental prostheses manufactured using SLM additive technology. Dental prostheses (crowns, two-unit bridges, thee-unit bridges) made from cobalt-chromium alloy on the device Mlab cusing R (Concept Laser, USA) via SLM technology. to-piece batch from each type of prostheses were produced. Subsequently, the pre- and post-heat treatment change in prosthesis geometry compared against the original.stl model was examined using GOM Inspect software (GOM, Germany). Crowns and two-unit bridges did not meet the normality requirement, therefore a non-parametric t-test (Wilcoxon test) was applied for variation comparison. Three-unit bridges met the normality criterion, therefore a parametric t-test was used to identify statistically relevant variations in dependent samples. Based on the results, we may conclude that the crowns and two-unit bridges manufactured via SLM technology do not change their geometry prior to or following the heat treatment. Three-unit bridges undergo geometry changes, therefore the heat treatment must be performed before the bridges are removed from a manufacturing platform.

Friction effect between joints needs to be considered in the fast changeover process of the dulcimer robot which is oriented to precise position control. A complete nonlinear dynamic equation with coulomb friction model for a six-degree-of-freedom robot is proposed. Based on Solidworks and Matlab SimMechanics dynamics model, the transformation and simulation of the above dynamic equations are completed, and the joint motion parameter recognition for the end positions is obtained. The results show that with and without considering the friction, the maximum difference on the moment response of joints of the robot is 7%. In order to precisely control the movement of each joint, a track tracking method combining traditional PID control and adaptive fuzzy PID control is proposed, and the angular difference of each joint track can keep within the range below 0.08 rad. The research process and results provide a theoretical reference for improving the high-speed position accuracy and evaluating the response characteristics of the multi -degree-of-freedom dulcimer robot, and have important engineering reference for ensuring the accurate acquisition of the multi-degree-of-freedom robot's motion.

The Internet is becoming more and more accessible and widespread. With a growing user base, we also encounter more often the anti-social behavior of users. One of these forms of behavior is a trollism. The problem of troll's comments regulation becomes more and more important. One of possible solutions is a recognition of trolls by machine learning models. The work deals with the behavior of trolls on the Internet, the possibilities of the trollism detection and types of data, which can be used to it. The proposed approach is based on the use of Support Vectors Machine, Multinomial Naïve Bayes, and Logistic Regression. The best results were achieved by Multinomial Naïve Bayes model up to 0,92 of Recall.

Predictive analytics has a significant potential to support different decision processes. We aimed to compare various machine learning algorithms for the selected task, which predicts credit card clients' default based on the free available data. We chose Random Forest, AdaBoost, XGBoost, and Gradient Boosting algorithm and applied them to a prepared data sample. We experimentally evaluated the classification models within metrics like accuracy, precision, recall, ROC, and AUC. The results show a very similar performance of the selected algorithms on this dataset. The Gradient boosting (0.7828) achieved the best performance within AUC, but the best precision for target class 1 reached the Bagging algorithm (0.72). The simple data processing brought only minimal improvements in individual metrics. Our results are comparable to the mentioned studies instead of MCC metrics that resulted in better value (0.4111) achieved by the Gradient Boosting model.

The invention of certain systems/tools for text transcription for people who are visually impaired or blind stands as a surge in technology and helps the people become independent, learned, and skillful. In the past decades, several systems/tools have evolved. However, each one of these systems/tools has advantages and disadvantages, limitations and strengths, and functional analysis accuracy. In this paper, the Braille system, the types of Braille, and tools which are applicable and most suitable with the Braille system for teaching mathematical geometry are explored. Thus, the Nemeth Braille code which stands out for teaching mathematical geometry is explicitly explained in this paper. The Nemeth Braille code is an advanced mathematical application of the Braille code which is used for teaching primitive and advanced mathematical geometry. This paper includes a review of the existing Nemeth Braille code and other Braille system. It introduces a software development that can be used for accessing and transcribing text documents containing ordinary mathematical geometry (which include shapes, formulas, functions, and equations) into Nemeth Braille code readable formats.

Digital technologies have pervaded medicine and healthcare systems and brought innovations with unprecedented speed, benefiting all stakeholders from patients to healthcare professionals, researchers and administrators. Health outcomes are defined as the measurable change in health as a result of interventions. The ultimate goal of medicine and health systems is to improve patients' health outcomes. Digital technologies have brought a revolution in the measurement of health outcomes from sensors and digital biomarkers recording physiological and behavioural data to the more precise measurement of patient reported outcomes and experiences - how themselves feel about the effect of health interventions or the participation in healthcare. From the analysis of big data to simple web surveys, the new possibilities and innovative solutions bring new insights but new methodological challenges and ethical dilemmas as well. This presentation will summarise why health outcomes matter to health economists and what are the contributions and ongoing research projects of the HECON - Health Economics Research Center in the measurement of health outcomes via digital technologies.
