The universities motto is "Great labor overcomes everything."The Carol I National Defence University seeks to train military and civilian experts in security and national defense. It undertakes scientific studies related to these matters when requested by relevant state authorities. The university is a member of the International Association for Military Pedagogy (IAMP), whose members include military and civilian professionals from military institutions of advanced learning.
The paper shows the feasibility of reconstructing signals from a computer monitor by intercepting its compromising electromagnetic radiation. For the detection and reconstruction process, the pixel clock frequency of the HDMI interface was utilized. Based on this pixel frequency, its integer multiples were calculated, and the corresponding center frequencies were used to detect the unintended emissions. Reconstructed images are presented across six different frequency bands, representing the spectral harmonics of the pixel clock frequency. Furthermore, the paper discusses protective measures to prevent the leakage of sensitive information via compromising electromagnetic emanations.
This study considers the process of detecting a low-altitude, low-speed air object in the presence of ground clutter. The principal hypothesis assumes that improving the method could make it possible to increase the signal/noise ratio. A method has been improved for detecting a low-altitude, low-speed air object in the presence of ground clutter using a synchronous multi-radar system, which, in contrast to known ones, allows for the following: – a synchronous survey of the airspace in azimuth and range by two radars by emitting mutually orthogonal probing signals; – forming signals reflected from the air object at the output of the radar receivers; – incoherent, joint signal processing in a synchronous multi-radar system from two survey radars; – coordinated filtering of received signals; – formation of Doppler channels; – equalization by delay time and Doppler frequency; – formation of an additive processing channel where incoherent summation of signals is carried out and formation of air object detection marks in the additive channel; – formation of a multiplicative processing channel where multiplication of signals is carried out and formation of air object detection marks of the multiplicative channel; – combination of air object detection marks of the additive and multiplicative channels and formation of final detection marks. An experimental study was conducted on the detection of a low-altitude, low-speed air object. The use of a synchronous multiradar system made it possible to increase the signal/noise ratio by 4 times. Additional multiplicative signal processing provides an increase in the signal/noise ratio and improves the discrimination of the signal from the air object in the presence of ground clutter
Мета роботи. Кількісно оцінити витрати на енергоресурси для практичної підготовки водіїв категорій C і C1 на електричній вантажівці BYD T5 порівняно з ГАЗ-66 та потенціал покриття відповідної енергетичної потреби за рахунок власної сонячної генерації. Методи дослідження. Застосовано розрахунково-аналітичну модель на основі чинної нормативної бази. Враховано обсяг практичного керування, параметри вправи № 5, витрати на енергоресурси на одного курсанта, пропускну здатність автопарку та строк окупності. Проведено аналіз чутливості до тарифу на електроенергію, питомого енергоспоживання та середньої швидкості руху. Результати дослідження. За базовими параметрами витрати на енергоресурси становлять 9 809 грн на одного курсанта для ГАЗ-66 і 1 111 грн для BYD T5, що відповідає 8,8-кратній перевазі електричної вантажівки. Для 100 курсантів розрахункова економія становить близько 870 тис. грн. Окупність BYD T5 становить 257 курсантів, а повного комплекту із шести машин та енергетичного комплексу — 7,3 року. Сонячний масив потужністю 29,25 кВтп потенційно здатний забезпечити енергетичну потребу підготовки до 312 курсантів на рік. Теоретична цінність дослідження. Запропоновано поєднання моделі витрат навчального процесу з оцінюванням PV–BESS-енергозабезпечення автопарку. Практична цінність дослідження.

Поєднано оцінювання витрат підготовки військових водіїв на електротранспорті з оцінюванням потенціалу сонячного енергозабезпечення. Обмеження дослідження/майбутні дослідження. Модель не є повною оцінкою TCO/LCC. Подальші дослідження мають охопити повний профіль вправ, TCO/LCC і місячний профіль генерації. Тип статті: розрахунково-аналітична стаття (прикладне модельне дослідження).
The relevance of the study lies in the global extension of segment reporting requirements, driven by calls from the investment community and harmonization projects between countries. The article highlights a trend in segment reporting regulation, leading to numerous studies examining practices, determinants, value relevance, and the IASB’s IFRS 8 Post-Implementation Review. The objective of the study is to provide a comprehensive overview of existing literature on Segment Reporting, elucidate the methodology used (including bibliometric analysis, PRISMA framework, and ADO-TCM analysis), and present results and conclusions derived from the data analyzed through these methodologies. The study aims to contribute to the understanding of segment reporting practices and their implications for stakeholders in the financial reporting landscape. In the realm of positive outcomes, it is observed that the adoption of a management approach significantly enhances the accuracy of analysts’ forecasts. Furthermore, the alignment between segmentation notes and Management Discussion and Analysis (MD A) proves to be instrumental in augmenting the depth and effectiveness of analysis. Additionally, the implementation of IFRS 8 manifests as a noteworthy positive aspect, bringing about a quantitative upswing in reporting practices. Conversely, a less favorable aspect surfaces concerning the use of non-IFRS segment data. This alternative data source is associated with a decline in the precision of forecasts, concurrently giving rise to heightened levels of uncertainty in the analytical predictions.
The article considers a boundary value problem of the Dirichlet type for generalized analytic functions of arbitrary order n in simply connected domains. Using the method of conjugation of analytic functions, an explicit solution to the considered boundary value problem is obtained in the class of first-order generalized analytic functions, for the case when the boundary conditions are specified on an arbitrary circle centered at the origin. It is proven that in circular domains, solving of the studied problem reduces to sequential solving of the classical Riemann boundary value problem (conjugation problem) for analytic functions of a complex variable and two first-order linear Euler differential equations. Furthermore, it is established that the corresponding homogeneous Dirichlet problem for first-order generalized analytic functions in circular domains is unconditionally solvable, and its general solution depends linearly on six arbitrary real constants.
