Development of a Neuroergonomic Assessment for the Evaluation of Mental Workload in an Industrial Human–Robot Interaction Assembly Task: A Comparative Case Study
The disruptive deployment of collaborative robots, named cobots, in Industry 5.0 has brought attention to the safety and ergonomic aspects of industrial human–robot interaction (HRI) tasks. In particular, the study of the operator’s mental workload in HRI activities has been the research object of a new branch of ergonomics, called neuroergonomics, to improve the operator’s wellbeing and the efficiency of the system. This study shows the development of a combinative assessment for the evaluat...

APPLICATION OF ROBOTICS SYSTEMS FOR QUALITY INSPECTION IN INDUSTRY
Quality inspection (QI) is one of the key segments of modern industrial processes and has crucial role in meeting high standards and product expectations. Advanced QI systems and practices enable companies to create products that are safe, reliable and compliant with specifications, thereby improving their position on market and ensure customer confidence. The rapid development of technology results in dynamic changes in the QI segment. Trends in the application of principles and tools ...

IMPLEMENTATION OF A NOVEL BIOCLIMATIC-PASSIVE ARCHITECTURE CONCEPT IN SERBIAN AND POLISH RESIDENTIAL BUILDING SECTORS
This paper presents a novel integration of bioclimatic-passive architectural elements—Trombe walls, pergolas, and deciduous climbers—in the context of residential buildings in Eastern and Central Europe, a combination that remains largely underexplored in the current literature. The innovativeness of the proposed concept is reflected in the combined use of the following building elements: three types of passive Trombe wall (single-glazed, double-glazed, and triple-glazed), pergolas, and four ...

Research on the possibility of improving the safety and health and effectiveness of workers who perform manual work activities using exoskeletons
The main focus of the paper is to explore the possibilities of improving the occupational safety and health and effectiveness of workers who perform manual work in the automotive industry using industrial exoskeletons. Exoskeletons are mechanical devices that workers carry and that support workers and strengthen their physical abilities (strength and endurance) when performing difficult, manual and physically demanding tasks that cannot be automated (such as lifting loads and handling loads, ...

Serbian Export to the EU Market: A Dynamic Shift-Share Analysis
The paper deals with the analysis of Serbian export competitiveness in regards to the EU market in the period between 2012 and 2021, using the location quotient and dynamic shift-share analysis, which breaks down changes in exports into three components: the national, the industrial, and the regional component. The results show that EU countries are suitable destinations for Serbian products. Also, products from several Serbian sectors are attractive in the European market. The location quoti...

Domestic Competition, Trade Openness and Entrepreneurial Culture: Canonical Correlation Analysis
The paper analyses canonical correlations between domestic competition, trade openness and entrepreneurial culture. The research covered 141 countries ranked by World Competitiveness Index in 2019. Canonical correlation analysis is applied to find relationship between two canonical variables. The first canonical variable includes sub-indexes from Domestic competition and Trade openness pillars. The second variable contains sub-indexes from Entrepreneurial culture pillar. The results of the an...

Comprehensive Experimental Analysis of Electrochemical Jet Machining (ECJM) for Advanced Material Processing
This study examines the capabilities and optimisation of electrochemical jet machining (ECJM), a component of the electrochemical machining (ECM) production chain. A localised electrolyte jet helps remove material from selective areas; it is a suitable process for contoured parts and hard-to-machine material without inflicting thermal or mechanical stresses. In this regard, the study incorporates details of an experimental layout and variation in parameters in terms of voltage, electrolyte co...

Kinetic investigation of phenylselenoetherification of some Δ4-alkenols in presence of catalytic amount of CoCl2
The phenylselenoetherification of unsaturated alcohols is the one of the most rapid and convenient methods for formation of THF and THP type of rings. The convenient position of a double bond and a hydroxyl group in an alkenol can easily lead to formation of corresponding cyclization product. The reaction of selenium electrophiles with alkenols is a stereospecific anti addition where the nucleophile (pendant hydroxyl group) attacks usually at higher substituted carbon atom (Markownikoff stere...

Biological evaluation of the 3,4-dihydro-2(1H)-quinoxalinones and 3,4-dihydro-1,4-benzoxazin-2-ones
In order to investigate new potential therapeutically active agents, we investigated the biological properties of two small libraries of quinoxalinones and 3,4-dihydro-2(1H)-quinoxalinones (Fig. 1). The results obtained showed that compounds 5, 9–11 have good cytotoxic activity against HeLa cells where the lowest IC50 ǀalue ;ϭϬ.ϰϲ ± Ϭ.ϴϮ μM/ŵLͿ ǁas measured for compound 10. Additionally, the most active compounds (5, 9–11) showed much better selectivity for MRC-5 cells (up to 17.4) compared...
