A methodology is proposed for modifying computer ontologies (CO) for electronic courses (EC) in the field of information and communication technologies (ICT) for universities, schools, extracurricular institutions, as well as for the professional retraining of specialists. The methodology includes the modification of CO by representing the formal ontograph of CO in the form of a graph and using techniques...
Traditional availability, reliability, and safety models face the dimension problem due to a huge number of components in modern systems, motivating further research in this field. This paper focuses on multi-fragmental and multiphase models for availability and functional safety assessment of the information and control (I&C) systems with two-cascade redundancy considering design faults manifestation...
Electrocardiography is an examination performed frequently in patients experiencing symptoms of heart disease. Upon a detailed analysis, it has shown potential to detect and identify various activities. In this article, we present a deep learning approach that can be used to analyze ECG signals. Our research shows promising results in recognizing activity and disease patterns with nearly 90% accuracy...
This work aims to create an ANN-based system for a musical improviser. An artificial improviser of "hearing" music will create a melody. The data supplied to the improviser is MIDItype musical data. This is the harmonic-rhythmic course, the background for improvisation, and the previously made melody notes. The harmonic run is fed into the system as the currently ongoing chord and the time...
Virtual digital representation of a physical object or system, created with precision through computer simulations, data analysis, and various digital technologies can be used as training set for real life situations. The principal aim behind creating a virtual representation is to furnish a dynamic, data-fueled, and digital doppelgänger of the physical asset. This digital counterpart serves multifaceted...
Large concrete structures such as buildings, bridges, and tunnels are aging. In Japan and many other countries, those built during economic reconstruction after World War II are about 60 to 70 years old, and flacking and other problems are becoming more noticeable. Periodic inspections were made mandatory by government and ministerial ordinance during the 2013-2014 fiscal year, and inspections based...
We consider the real-life problem of planning tasks for teams in a corporation, in conditions of some restrictions. The problem takes into account various constraints, such as for instance flexible working hours, common meeting periods, time set aside for self-learning, lunchtimes and periodic performance of tasks. Additionally, only a part of the team may participate in meetings, and each team member...
Creotech Instruments is advancing a game-changing sCMOS camera series. The Final Prototype Model of an astronomical camera for Space Surveillance and Tracking (SST) is in the test campaign phase. Designed for SST, NEO, and debris detection, its adaptable platform suits quantum tech and biological microscopy. Edge computing sets it apart, leveraging FPGA-based SoC for real-time processing and Linux-based...
In this paper we derive mathematical description of TCP (Transmission Control Protocol) retransmission probability based on Jacobson’s smoothing algorithm that belongs to EWMA (Exponentially Weighted Moving Average) category. This description is parametrized on the probability density function (pdf) of RTT (Round Trip Time) samples and α, β – two primary parameters of Jacobson’s algorithm. Although...
The aim of the paper is to show how graduated engineering students in classical ICT view practically the advent of the QIT. The students do their theses in El.Eng. and ICT and were asked how to implement now or in the future the QIT in their current or future work. Most of them have strictly defined research topics and in some cases the realization stage is advanced. Thus, most of the potential QIT...
The method of evaluating the resonant frequencies of multilayered resonator containing demagnetized ferrites is presented. The detailed solution of Maxwell's equations for such a structure by means of the radial modes matching method for TE0mn modes is given. The results of calculations using developed and launched computer program are given. Results of calculations are compared with those obtained...
Many contemporary technical elements (such as railings, light switches, power sockets, security cameras, etc.) have a very different aesthetic from the historical interiors to which they are added. Their placement in historical architectural interiors raises the question of their visibility and their power to disrupt the visual unity of an indoor space. Using logical argumentation and knowledge from...
This paper discusses public spaces for special purposes, increasingly often designed in Poland, including the gardens presented, which a form of land development. The aim of this study is to present various types of practical activities using sensory gardens for the education and rehabilitation of children and people with disabilities. An increasing number of such spaces is being created, and they...
The aim of this paper is to trace the links between Professor Wiktor Zin’s artistic work and activity and his hometown - Hrubieszów. The Professor’s message on the importance of documenting and protecting this heritage has not lost its relevance, especially today, when historical wooden buildings are being destroyed. The paper concludes that the place of birth was an important motif in Wiktor Zin’s...
For centuries, the roof has been a reminiscence, the symbol of basic human shelter and territory. Using the example of several ethnic groups living in Southeast Asia, Bhutan and Poland, the basic determinants of roof shape creation in vernacular architecture are discussed and similarities highlighted. In wooden architecture in different regions of the world, the form and construction of the roof are...
This article describes the role of street art in the context of the city’s competitiveness and creativity. In addition, the study examines the perception of street art by residents of various cities in terms of its acceptance, associations, and impact on the image and competitiveness of cities. Based on selected examples from Poland, manifestations of street art were indicated as a determinant of...
Congestion is a significant problem affecting the operational processes of a hospital’s outpatient department (OPD). Congestion especially affects the OPD’s architectural space, due to the increased number of patients. Recently, digital tools have been used in healthcare systems to reduce congestion and help the OPD improve its operational processes; one of these tools is the virtual examination room...
Rapid urban development in the second half of the 20th century led to increasingly urbanized structures. As a result, industrial areas that were previously located on the periphery have found themselves in the inner city areas, contributing to the deterioration of the environmental quality and the attractiveness of these areas. Their closure requires the revitalization of decayed areas. The aim of...
During the interwar period, period many examples of sports facilities were built in the Second Polish Republic. These groups of facilities had one function designed for practicing a specific sport discipline but also multifunctional facilities were also built. Sports centres played a role not only enabling amateur exercises and improving sports skills but they were also the seats of sports societies,...
Glass is a significant material in shaping contemporary architecture. Its main feature is transparency, which is related to the possibility of letting daylight into building interiors. Glass facades mark the almost invisible border between the interior and exterior space, which is a source of endless design inspiration. This situation is facilitated by the development of technology and knowledge on...
