Specifically, we present the number of publications over the years, the areas to which the publications belong, the authors, the journals, and a (…)
One of the most progressive technologies in foundry is die casting, where a significant part is formed by die casting of castings of a lower weight category. In the case of castings cast by pressure casting technology, one of the important quality indicators is the internal quality of the casting presented by internal defects. In addition to the alloy used, the shape of the mold and the filling chamber (…)

Furthermore, this paper seeks to address with analysis and evaluation of the elements of the adaptive assembly system. The work presents a taxonomy in the field of adaptive assembly. The core of the work consists of the design of the architecture of individual systems. It is necessary to broaden knowledge about this topic (…)
As a potential source of a major accident, aviation fuel tanks represent a potential source of danger not only for the airport but also for businesses in the vicinity of the airport. Fire is one of the main hazards associated with the operation of fuel storage tanks. Depending on the type of storage tanks, there may be a fire in the tank itself or a fire in the bund. An important factor in an actual fir (…)
A new method to simulate the varying static receptance of a thin-walled workpiece based on the Cholesky decomposition is presented in this paper. In this method, the system stiffness matrix is updated by subtracting the elemental stiffness matrices of the removed elements from the initial system stiffness matrix. The updated system stiffness matrix is permuted by using a novel method based on element re (…)
The process design for the manufacturing of surface structures with functional tribological properties is a major challenge when machining workpieces with freeform surfaces. Distortion effects of the structures and limitation of CAD/CAM-systems require the development of novel technological solutions. The paper presents a new approach for designing the machining processes of functional textures on freef (…)
Human resource management (HRM) is of strategic importance for the management of organizations, therefore management measures in the field of HRM are of considerable importance for the performance of any organization. For the management of HR in the organization, it is important to have an information system that provides timely and reliable information necessary for decision-making. The article is focu (…)
When manually processing complex contours or surfaces, there is a risk of incomplete or unnecessary multiple processing. The support of such processes with an augmented reality (AR) application will be presented in this work using the example of manual deburring. Firstly, the positions of the component and tool are determined based on camera recordings. For this purpose, approaches for 6 Degrees of Fre (…)
Among the key activities of managing an organisation is to be able to make timely and correct decisions. Making the right decision is necessary to ensure the organisation's competitiveness [Lestyanszka 2014a]. Organisations are trying to reduce production costs as much as possible, but this, on the other hand, brings negatives in the form of products that do not meet customer expectations. This phenomen (…)
Due to the fact that emission reduction has become an important topic and due to the upcoming EURO 7 standard, the automotive industry is focusing on reducing the carbon footprint. One of the ways to do so is enhancing the efficiency of internal combustion engines by technologies such as cylinder deactivation. This technology offers fuel economy benefit, therefore, also CO2 emission reduction. However, (…)
Every advanced knowledge about the process, object, or workplace is fundamental. It concerns current trends (digitalization, automation, intelligent industry) and the need to fill the missing technological gaps. Their goal is to increase quality and competitiveness. Therefore, this article aims to present a framework of the systematic approach as an affordable way to obtain relevant information about th (…)
The article is devoted to the identification of friction in the joints of a 3-DOF manipulator with fluidic muscles. For the identification of friction, four different models were proposed, namely linear friction model, extended friction model, non-linear friction model and LuGre model. The values of the coefficients of the proposed models were estimated in the Matlab Simulink program environment based o (…)
Effective business management is based on the use of relevant information. To be useful, information must be available in the right quantity, quality, place and time. In an enterprise, this function is often provided by an information system. The enterprise information system is one of the key factors for the competitiveness of not only large and multinational companies but also small and medium-sized e (…)
This paper deals with the kinematic and dynamic analysis of a two-element robot model. We have solved the problem using inverse kinematics.
