This narrative review focuses on biodegradable magnesium-based materials, emphasizing their biocompatibility, mechanical properties, and clinical potential for orthopedic applications. The aim of the study is to assess the suitability of magnesium alloys - particularly the ZX00 alloy (Mg-0.45Zn-0.45Ca)-for the stabilization of the tibiofibular syndesmosis (syndesmosis tibiofibularis). The work summarizes recent advances in material science, alloy optimization, surface modification, and additive manufacturing techniques that enhance the corrosion resistance and mechanical integrity of magnesium implants. It compares the biomechanical performance of...
Using Power BI to Analyse Withdrawals from Company Dispensing Machines
Andrea Šimerová, Pavel Raška, Michal Šimon
Acta Mechanica Slovaca 2026, 30(1):16-19 | DOI: 10.21496/ams.2026.009
This paper describes the design, development and deployment of an interactive Power BI report intended for the finance department of a manufacturing company. The report analyses material withdrawals from in‑plant dispensing machines and relates them to monthly production hours at the cost centre level. A complete workflow is presented, including data acquisition from multiple Microsoft Excel sources, data cleaning and transformation, construction of a relational data model, and the definition of key metrics using Data Analysis Expressions (DAX). The resulting solution comprises a set of report pages for (i) comparing total withdrawals with production...
Numerical Analysis of the Buildability of a 3D-Printed Cylindrical Concrete Wall: A VoxelPrint-Abaqus Approach

Additive manufacturing (AM) of silicate-based materials has emerged as a significant research area, with adoption across construction, automotive and electrical engineering, as well as art and design. The rheology of fresh mixtures, along with process parameters (printing speed, layer height, bead width), strongly influences printability and buildability. In addition to experiments, numerical methods - particularly finite-element analysis - are increasingly used to predict the structural response and assess the stability of printed components. This study investigates the buildability of an extrusion-printed cylindrical concrete wall using a finite-element...
Visual-Inertial Tracking in Augmented Reality: Impacts on Wayfinding Behaviour and User Experience
Tomáš Macháč, Petr Hořejší, Michal Šimon
Acta Mechanica Slovaca 2026, 30(1):26-32 | DOI: 10.21496/ams.2026.008
Accurate pose estimation is a prerequisite for usable handheld augmented reality (AR) wayfinding indoors, yet users experience navigation less as a positioning number and more as a sequence of micro-corrections shaped by visual-inertial tracking. This paper examines how inertial measurement unit (IMU)-driven drift, heading instability and re-anchoring events influence spatial orientation, trust and comfort during smartphone-based AR guidance. We introduce a human-computer interaction (HCI)-oriented evaluation approach that couple's sensor diagnostics (e.g., inertial bias indicators, heading stability, and relocalisation frequency) with human measures...
Numerical Kinematic and Dynamic Analysis of a 6-DOF Industrial Manipulator Using a Lagrangian Formulation
Martin Uzik, Anton Hovana
Acta Mechanica Slovaca 2026, 30(1):34-41 | DOI: 10.21496/ams.2026.010
This paper presents a numerical kinematic and dynamic analysis of a six-degree-of-freedom (6-DOF) industrial manipulator based on the Denavit-Hartenberg convention and the Euler-Lagrange formulation. The objective of the study was to combine analytical modeling with numerical implementation in order to evaluate joint torque requirements relevant for actuator dimensioning and control system design. The forward kinematic model was derived using homogeneous transformation matrices and validated through MATLAB-based simulation. A predefined circular spatial trajectory was applied to determine joint positions, velocities, and accelerations. Based on the...
Process Management Model of a Control System in Organizations Providing Quality Services for the Automotive Industry
Milan Ďuračka
Acta Mechanica Slovaca 2026, 30(1):42-50 | DOI: 10.21496/ams.2026.012
The article addresses the issue of the effectiveness of corporate control systems in the environment of the automotive industry. It presents a proposal for an innovative model of process management and control based on an analysis of the current state, contextual interviews, and process mapping. The aim is to demonstrate that control does not necessarily have to be perceived as a repressive tool, but rather as a motivating element supporting organisational improvement and development. The paper presents the results of the implementation of new process and audit procedures in a company providing quality-related services for OEMs, as well as their contribution...
Optimization of Paper Machine Vacuum Systems Using Turboblowers: Industrial Implementation and Energy Savings
Peter Demčák, Milan Fiľo
Acta Mechanica Slovaca 2026, 30(1):52-56 | DOI: 10.21496/ams.2026.xxx
Vacuum system on paper machine line is one of the main drivers for electricity consumption. By optimizing vacuum usage, optimizing water flow measurement, and implementing Turboblowers, mills can significantly reduce energy consumption in the vacuum system. Furthermore, exhaust heat recovery, regular maintenance, and tailored dewatering solutions help achieve remarkable energy savings, ultimately benefiting both the environment and operational efficiency.
Metrological Comparison of Ocular Tonometers for Optometric Use
Stela Levická, Dominik Pražák, Václav Sedlák, Eliška Najmanová, František Pluháček
Acta Mechanica Slovaca 2026, 30(1):58-63 | DOI: 10.21496/ams.2026.013
This paper presents an international metrological comparison of non-contact tonometers used for measuring intraocular pressure (IOP), a critical parameter in glaucoma diagnosis. Since non-contact tonometry is affected by biological variability and lacks direct linkage to SI units, reliable calibration standards are essential. A newly developed universal model eye, independent of specific manufacturers and traceable to SI units, served as the primary metrological standard. The comparison involved tonometers tested at institution in the Czech Republic and Slovakia according to the ISO 8612:2009 standard under controlled laboratory conditions. Accuracy,...
