This paper presents a Vienna-focused conceptual framework for urban microclimate analysis in smart sustainable city design. The study is based on a targeted review of microclimate monitoring approaches, GIS-based morphology indicators, and simulation workflows, which is used to identify recurring limitations and translate them into a multi-layer structure. This framework models how...
In this paper the problem of obtaining a complete picture of monitored military objects is resolved with computer vision tools. The research is focused on the necessity for the correctly arrangement of photos obtained in different ways to promptly obtain a comprehensive picture of the situation in an area of monitored military operation. The consecutive stages with functional operations are...
This article considers the Dirichlet type integrals, for which closed form formulas have been obtained. In particular, it is proven that all these integrals are rational numbers. The Lobachevsky integral formula is also considered.
This article considers the method of posterior predictive distributions as an effective tool for checking the correspondence between data and the
statistical model. The examples considered show that in the role of posterior predictive testing statistics, dispersion measures should be taken, because the central tendency measures do not give the natural expected results.
When configuring temporary or hastily built, field or other computer networks, it is necessary that they meet all modern standards and requirements for computer networks and for cybersecurity when connecting to the Internet. This study proposes an approach for designing, configuring and setting up a firewall for a computer network, built and configured on the basis of a Raspberry Pi...
Mobile tourism applications are expected to provide not only functional usability but also emotionally engaging experiences. This study explores how visual style influences emotional engagement in mobile tourism interfaces. Focusing on a comparative sample of Bulgarian tourism apps, the research applies a mixed-method UX design combining user ratings, emotional assessment, and targeted...
This paper presents the steps and the possibility realization a "Brute force" reduced attack implementation on 256_AES encrypted voice stream in a MATLAB Simulink environment. The research focus is selecting the correct decrypted ciphertext from many candidates. Possible selection hypoteses leading to the interpretation of the transmitted information are considered.
Nowadays, unmanned aerial systems play a very important role in the economy, environmental protection, research, and military operations. This is accompanied by constantly increasing requirements for the quality and accuracy of the information received and the commands issued.
The elements of these systems operate and perform their tasks by transmitting data and commands over communication...
This article presents a comprehensive study of classical and modern approaches to enhancing images captured in low-light conditions. An adaptive ensemble method is proposed that combines four classical image processing algorithms and automatically weights them based on local quality. The developed system uses CLAHE, gamma correction, the Retinex algorithm, and automatic contrast stretching as...
We would like to present the dictionary we are collecting already for two decades as well as the electronic lexicographical system which is used for the creation of this dictionary and was especially developed twenty three years ago for this purpose. It is a good example of almost-without-financing long-term development strategies of IT systems for language technology purposes, and it could be...
University training within the Fourth Industrial Revolution should equip students with knowledge and skills to face the challenges of the labour market and, more importantly, successfully navigate their daily personal and professional lives. Given the ongoing development of digital technologies, learning in the 21st century is a significant challenge. Although the use of AI tools in the...
Artificial intelligence has become part of daily life in universities, for both students and educators. However, despite the fact that we all understand that AI is shaping and changing the education paradigm, the question of how often and for what we use AI remains on the agenda. Yes, AI has made many daily tasks easier; however, are students using AI for tasks they could solve without it? The...
Colorizing monochromatic images is crucial for enhancing the informativeness of visual data in modern information technology and computer vision systems. However, automatic colorization poses an inherently ill-posed mathematical challenge due to the multimodal nature of color distributions, where multiple valid color mappings exist for any given grayscale input. This article conducts a...
This paper examines the DCSync attack from an adversarial perspective, focusing on its operational logic, execution techniques and implications for both offensive tradecraft and defensive detection. Rather than treating DCSync solely as a credential access technique, the study situates it within the broader context of Active Directory exploitation and privilege abuse, emphasizing its role in...
This paper presents a comparative analysis of the command-and-control (C2) frameworks PoshC2 and SliverC2, examined within the context of evolving adversarial tradecraft, shifting infrastructure paradigms and the increasing maturity of defensive capabilities. While C2 frameworks are traditionally associated with the post-exploitation phase, this study adopts a broader perspective, arguing that...
In the era of rapid technological advancement, access to digital opportunities makes it possible to prepare students for the jobs of the future and have a positive influence on the development of their future-proof skills, which will be of paramount value. Amid unpredictable changes in the labor market, critical thinking skills are becoming increasingly strategic and enabling labor market...
Modern day full text search relies on a simple yet robust inverted index data structure to find documents matching a text query. However, this approach is limited by the required spelling checker, which often has memory requirements comparable to the index itself. In this work, a novel approach to text indexing is introduced. Based on the navigable small world data structure, it offers a...
High-risk facilities (HRF) are subject to strict regulatory oversight, encompassing mandatory registration, periodic technical inspections, and systematic maintenance of technical documentation. In practice, the management of these processes is hindered by a range of organizational shortcomings: facility data are scattered across heterogeneous registers and files, there are no automated...
The aim of this article is to present an approach for preventing service overload in Elastic Compute Cloud (EC2) within Amazon Web Services (AWS). The study analyzes methods for preventing overload of virtual machines in AWS EC2 by comparing vertical and horizontal scaling. Developed block diagrams are presented to visually illustrate the architecture and processes involved in dynamic resource...
One of the most effective ways to test a company’s security posture is through red team assessments and targeted penetration testing. This article defines one of the most effective approaches for determining the scope of the tests and the stages they go through.
The stages include getting to understand the potential attackers, their tactics, techniques and procedures, the modus operandi and...
The accelerating processes of digital and energy transformation are fundamentally reshaping contemporary societies, economies, and governance systems. While technological innovation and the transition to sustainable energy are essential for long-term development, their success increasingly depends on the level of public trust. In this context, trust emerges as a critical factor and a central...
This paper examines how students used artificial intelligence (AI) while writing professional bachelor theses and asks how those patterns can be described in a way that is useful for future support and governance in higher education. The study compared the 2024 graduating class and the 2025 graduating class from the same Lithuanian institution. The target population was 399 students, and the...
This research described is focused on computer vision tools implemented for detection of a particular military object (or many objects) in a observed scene, given a reference image(s) of the object(s). An algorithm for detecting a specific object based on finding point correspondences between the reference and the target image is designed. It can detect objects despite a scale change or...
