comparative analysis

This review paper provides a comprehensive comparative analysis of abandoned object detection algorithms, specifically contrasting rule-based approaches with artificial intelligence (AI-based) models. The manuscript synthesizes existing research, technical documentation, and publicly available benchmark data to evaluate the applicability of these approaches in dynamic video surveillance environments.

This article presents an expanded experimental comparison of the effectiveness of machine learning methods for the task of three-class sentiment classification (negative, positive, neutral). The research focuses on the specific domain of Ukrainian-language citizen appeals to city administration bodies, which is a relevant and practically significant task for the development of modern e-Governance and decision support systems.

The article investigates the effectiveness of structural solutions for reinforcing steel frames of frames designed to withstand explosive loads. Design approaches for resistance to progressive (disproportionate) collapse are considered. A comparative analysis of options for strengthening and complete replacement of the structure is performed, taking into account the cost of steel, manufacturing and installation work.

The article considers the issues of increasing the efficiency of steel combined sprengel trusses by developing rational design solutions by improving their stressed-strain state. The research methodology is based on a comparative analysis of technical and economic indicators in terms of material consumption of traditional typical and lightweight combined steel trusses. Three levels of adaptation are considered that affect the consumption of steel in the panels of the upper chord of a combined truss. Examples of achieving structure efficiency of trusses are given.

The article examines the issue of the occurrence and influence of bending moments on the bearing capacity of a combined steel truss made of rectangular bent-welded profiles. A comparative analysis of technical and economic indicators in terms of material intensity, labor intensity, and cost of traditional-typical and lightweight combined steel trusses was carried out. The paper examines steel trusses of long-span buildings with a span of 30 m. The force graphs (bending moments and axial forces) for various calculation schemes of the combined steel truss are shown.

Для прийняття об’єктивних обґрунтованих рішень у всіх сферах діяльності необхідно створювати інформаційні системи підтримки прийняття рішень на основі статистичних даних і експертних оцінок та з використанням відповідних математичних моделей та методів. Запропоновано процедуру побудови інформаційної системи підтримки прийняття рішень за методологією системного аналізу на основі сучасних методів і моделей прогнозування, яка надає можливість оцінювати та прогнозувати фінансово- економічні та інші процеси в умовах впливу збурень довільних типів та різної природи.

The article notes that the integration of the Ukrainian economy into the EU is partially hampered by purely logistical factors. The positions of Ukraine in the world ranking of the Logistics Performance Index are analyzed. Attention is focused on the component of «logistics competence», which is significantly behind the average European level. The authors suggested that the existing backlog could offset the new generation of potential managers who were the target audience of this study.

This article examines the main generally accepted indicators for assessing certain aspects of public administration, which are used in international practice. The study of these indicators will provide a general description of the quality of the existing system of public administration and the effectiveness and efficiency of its operation, as well as reflect the existing features of socio-political life and economic policy implemented in the country by public (primarily and largely public) government and administration.
