    Explozívne tvárnenie dielcov a jeho podstata
    (University of Žilina, 2025) Moravec, Ján; Melo, Branislav
    The article focuses on explosive forming of metals, in this case pipes, where the text provides the necessary information about the process of this type of forming. In the second part, based on knowledge from the theory of metal forming, a theoretical analysis of the process is given.

    Bezpečnosť účastníkov cestnej premávky a ich vplyv na vnímanie dopravnej situácie
    (University of Žilina, 2023) Ballay, Michal; Macurová, Ľudmila; Kohút, Pavol; Rédl, Miroslav
    When analysing an accident scene, one of the significant tasks is to evaluate the driver's ability to perceive the traffic situation according to different aspects. Currently, there are various eye movement measurement systems designed to perform a high-quality reconstruction of the direction of eye movement of road users depending on time. In addition to the basic physiology of the perception of road users, the paper deals with using the Viewpointsystem® measurement system designed to analyse eye movement when perceiving the traffic situation. The article assesses the development of traffic accidents in the Slovak Republic according to the consequences of traffic accidents and categories of road users. As part of determining the decisive moment for a collision situation, an analysis of the direction of the eye movement of the driver of the vehicle during a dangerous traffic situation while driving on a road section located in a rural area is performed.

    Posúdenie stability lesného kolesového traktora vybaveného hydraulickou rukou
    (University of Žilina, 2023) Dižo, Ján; Blatnický, Miroslav; Ishchuk, Vadym; Lovska, Alyona; Fidrik, Filip
    Wheeled forests tractors are inseparable part of a forest economy. Wheeled forests tractors serve for logging of logs in forests. Current wheeled forests tractors are usually equipped with hydraulic arms, which allow to expand the utility of such tractors. A tractor with a hydraulic arm can handle with wood logs without a need additional forest machine, which helps to reduce costs. On the other hand, it is necessary to analyse tractors abilities, which has such an additional equipment. This article is focused on assessment of stability of a heeled forest tractor, which is equipped by such a hydraulic arm. As the hydraulic arm changes the centre of gravity of an entire tractor, mainly with the load, safe operation of the tractor needs to know limit conditions of stability under the maximal load and in the given slope inclination.

    Rozbor bezpečnosti letov UAV a konspekt aktuálnych legislatívnych požiadaviek
    (University of Žilina, 2021) Škultéty, Filip; Kandera, Branislav; Janovec, Michal
    Despite the recent legislation, which has been formed in the last five years to its current form, the safety for the UAV operation is borne by the pilot, as he/she is the one who is responsible for the direction of UAV movement thus for any collision. For this reason, it is necessary to increase the safety of UAV operations outside the duties and competencies of the pilot at a distance, for example, through anti-collision systems and air traffic management systems. This article was initially focused on analysing aviation events in Slovakia associated with the operation of the UAV. Another factor that significantly affects the operation of UAVs to a large extent is the legislation itself. A special part was devoted to the legislation in terms of airspace determination, procedures and rules of operation of the UAV. From a legislative point of view, it is currently an important aspect to define the correct and reasonable level between the restrictions in order to increase the safety of operation only on an indispensable scale, not to be very restrictive to operators.

    ANALÝZA RUŠENIA SIGNÁLU GNSS NA LETISKU POPRAD- TATRY
    (Žilinská univerzita v Žiline, 2020) Novák, Andrej; Novák Sedláčková, Alena; Stelmach, Anna
    The paper is focused on the GNSS signal interference during the airport approach procedures at small Slovak regional airport Poprad-Tatry. The paper analyzes the simulation of the situation during the identification and monitoring of GNSS signal interference by ground station situated at the airport. Nowadays is still important to develop air transport and increasing the safety and continuity of provided services even at small regional airports. One of the most appropriate possibilities is to use at this kind of airports with insufficiently equipped navigation infrastructure the GNSS approach. The monitoring of reliability of this system and implementation of monitoring the GNSS signal interference in the final phase of the instrument approach will increase the safety of the flight.
