In recent times there has been a shift in the interpretation of Aristotle’s logic. Many researchers have pointed out that the concept of existential import appears in Aristotle’s logic and philosophy, and that Aristotle worked with the concept of empty terms although his concept&#x...

Stanisław Leśniewski developed a system of logic and foundations of mathematics that considerably differs from Russell and Whitehead’s system. The difference between these two approaches to logic is significant primarily in the case of Leśniewski’s calculus of names, Ontology, and the concep...

The article reports on the influence of a compressive macrostress in the Ti(Al,V)N films on their mechanical properties, structure, microstructure, and resistance to cracking. The macrostress is controlled by the energy Ebi delivered into the growing film by bombarding ions. The Ti(Al,V)N&#x...

Magnetron-based gas aggregation cluster source (GAS) was used to prepare high-purity CuO (cupric oxide) nanoclusters on top of sputter-deposited thin film of tungsten trioxide (WO3). The material was assembled as a conductometric hydrogen gas sensor and its response was tested and evaluated....

Amorphous quaternary Zr–Hf–Al/Si–Cu thin-film metallic alloys were prepared by non-reactive magnetron co-sputtering using four unbalanced magnetrons equipped with Zr, Hf, Al or Si, and Cu targets. The Zr, Hf and Al or Si targets were sputtered in dc regimes while the Cu target ...

The ion-flux characteristics at a substrate position and the corresponding discharge characteristics were investigated during controlled low-temperature (300 °C) reactive HiPIMS depositions of thermochromic VO2 films onto conventional soda-lime glass substrates without any substrate bias voltage and without...

Augmented reality (AR) glasses with GPS navigation represent the rapidly evolving technology which spares (and externalizes) navigational capacities. Regarding the expected everyday usage of this device, its impact on neuroplastic brain changes and navigation abilities should be evaluated. This study&...

Barium titanate (BaTiO3, BTO) is a perovskite class material of remarkable dielectric, ferroelectric and ferromagnetic properties. Our previous studies on optical properties of BTO thin films proved high visible transmittance and sharp absorption edge at ~ 300 nm. Therefore the usage of ...

In this article, we deal with the problem of potential stigmatization and social exclusion of people that have voice/speech problems due to neck cancer, especially those who have lost their voice because of total laryngectomy, and we analyze how this potential stigmatization could&...

The developed helmet is tested for 8 impact configurations (4 impact directions for both anvils). The ECE R22.05 regulation [9] defines, that the maximum acceleration must not exceed 275 g and the maximum HIC must not exceed 2400 for each impact and the helmet fulfils the...

A total knee arthroplasty (TKA) is in rare cases followed by an extra-articular fracture of distal femur. One type of fracture is a simple extra-articular fracture (A1 according to Schewring and Meggitt). It can be stabilized only by surgical treatment. Several implant types are&#x...

The operation of steam turbines is related to the extreme conditions such as high pressure and temperature, which can lead to fatigue issues and subsequent undesirable problems. This paper is focused on the methodology for the fracture analysis of turbine casings. The evaluation me...

In electronic structure calculations, various material properties can be obtained by means of computing the total energy of a system as well as derivatives of the total energy w.r.t. atomic positions. The derivatives, also known as Hellman–Feynman forces, require, because of practical c...

The principle of emergence is, today, a key paradigm in the area of the development of systems of artificial intelligence. This article sketches the prospects for tackling emergence in artificial intelligence using Vopěnka’s alternative set theory applied to a model of interaction betwe...

Behavior of various, even hypothetical, materials can be predicted via ab-initio electronic structure calculations providing all the necessary information: the total energy of the sys- tem and its derivatives. In case of non-periodic structures, the existing well-established methods for electronic...

SymPy is an open source computer algebra system written in pure Python. It is built with a focus on extensibility and ease of use, through both interactive and programmatic applications. These characteristics have led SymPy to become a popular symbolic library for the scientific&#x...

In this paper a novel approach in developing a simplified model of a vehicle front-end is presented. Its surface is segmented to form an MBS model with hundreds of rigid bodies connected via translational joints to a base body. Local stiffness of each joint is calibrated&...

The objective of this study was to develop a sophisticated MRI-based model to simulate changes in the levator ani muscle (MLA) during vaginal delivery. The female pelvis and the fetal head were modeled by rigid bodies. The MLA and obturator were represented by Ogden material&#...
