Recent growth in online learning has created a need for reliable methods to monitor learner engagement, cognitive load, and fatigue. This study presents a deep learning framework that integrates eye-tracking data with electroencephalogram features to classify engagement levels in digital learning environments. Eye-tracking indicators of cognitive load, including pupil dilation, blink rate, fixation duration, and saccade velocity, were extracted from a publicly available dataset and combined with electroencephalography (EEG) measures. Engagement level was modelled as a three-class problem, including low, moderate, and high, using hybrid CNN-LSTM architecture designed to capture both spatial and temporal patterns. The model achieved an overall accuracy of approximately 89 percent with high precision and recall across categories. ANOVA analysis showed that no single feature could reliably distinguish engagement levels, underscoring the benefit of multimodal deep learning. The study highlights how combining eye-tracking measures with EEG signals can offer a clearer, real-time picture of learners’ cognitive states during e-learning activities. By detecting moments when attention declines or cognitive fatigue begins to set in, such systems can enable genuinely adaptive learning platforms, ones that know when to suggest brief breaks, adjust the pace of instruction, or provide timely, targeted support to help learners stay engaged.

This article addresses the challenge of building Android applications within secure, network-isolated environments where no direct internet connection is available. The primary objective is to develop a reliable method for the continuous integration and delivery (CI/CD) of Android artifacts under these constraints. The proposed solution methodologically integrates Docker containerization to ensure a standardized build environment with the Nexus Repository Manager for creating a comprehensive local mirror of all external dependencies, such as those from Google Maven. This local repository cache is then made accessible inside the isolated network via a configured nginx proxy server. The implemented system successfully enables a complete and automated Android build pipeline, entirely eliminating the need for external access during compilation. The results demonstrate significant enhancements in security by mitigating risks associated with public repositories, while also ensuring build stability, reproducibility, and protection against upstream outages. In conclusion, this approach provides a practical and robust framework for secure mobile application development in high-security or restricted corporate network infrastructures.

The article discusses the problem of feature selection when training machine learning (ML) models in the task of identifying fake (phishing) websites. As a solution, a set of key metrics is proposed: efficiency, reliability, fault tolerance, and retrieval speed. Efficiency measures impact of feature to prediction accuracy. Reliability measures how well feature distinct phishing from legitimate. Fault tolerance score measures empirical probability of feature to be valid and fulfilled. And retrieval speed is logarithmic time of feature extraction. This approach allows for the ranking of features into categories and their subsequent selection for training machine learning models, depending on the specific domain and constraints. In this article, 82 features was measured, and 6 fully-connected neural networks was trained to evaluate the effectiveness of metrics. Experiments has shown that proposed approach can increase the accuracy of models by 1-3%, precision by 0.03, and significantly reduce overall extraction time and so improve response rate.

Abstract: The scope of applying fiber-reinforced concrete in critical load-bearing structures, such as aerodrome pavements, is often limited by insufficient information regarding material behavior and life-cycle economics. This study addresses this gap by developing and evaluating an optimal hybrid mix of micro and macro-basalt fibers consisting of 1.5% and 0.5% of cement mass, respectively for high-performance airfield concrete, followed by a 30-year Life-Cycle Cost Analysis (LCCA). Mechanical testing confirmed the technical feasibility, showing significant performance gains over baseline concrete: 14.5% increase in compressive strength 72.8MPa and 18.2% increase in flexural strength 10.4MPa. These gains are attributed to enhanced durability, multi-scale crack control, and superior post-crack load-carrying capacity. The LCCA, conducted using a 6% discount rate, revealed that the hybrid option, which incurs a 13.03% higher upfront material cost, is economically viable only under the optimistic scenario where the improved durability eliminates the need for major rehabilitation over 30 years. This scenario yields a marginal LCC saving of 4% compared to the baseline. In conservative and moderate scenarios, the upfront cost outweighed the delayed or reduced rehabilitation costs. Overall, Hybrid Basalt Fiber Reinforced Concrete is a promising high-performance material that achieves cost parity if its durability benefits are maximized to prevent major rehabilitation. Future work should involve field trials and expanded LCCA incorporating operational downtime and risk-based performance modeling.

This article examines the design of efficient nodal connections for steel frame elements, taking into account international experience. A comparative analysis of the calculation approaches adopted in the European standard EN 1993-1-8, the Chinese standard GB 50017-2017, and domestic regulatory documents is provided. Particular attention is paid to the impact of calculation assumptions and consideration of the deformative rigidity of nodal connections on the performance of frame systems. To verify the validity of the adopted models, numerical simulation of flange connections was performed using the finite element method. The results of the study confirm that the use of modern regulatory approaches allows for a more accurate consideration of the actual performance of nodal connections and contributes to a more rational design.

The article examines the environmental impact of ferrous metallurgy waste, with particular emphasis on its contribution to the formation of the fine particulate fraction PM10. The analysis shows that dispersed materials generated during waste handling participate in the formation of stable aerosol structures, the role of which has long been underestimated due to fragmented data and limitations in monitoring. Previously unrecognized mechanisms of metal-containing particles contributing to the overall aerosol load were identified. Based on the synthesized information, a methodological approach is proposed that enables a new perspective on assessing the influence of metallurgical waste on ambient air quality.

In the current conditions of metallurgy development, the task of ensuring uniformity and stability of the raw material base is of key importance, as the main technological indicators and quality of the produced metal directly depend on these parameters. Agglomerate ore, which is an essential component of the blast furnace charge, has high requirements for the uniformity of its properties. Variations in the chemical and granulometric composition of agglomerate ore negatively affect the stability of the blast furnace operation, leading to increased coke consumption, reduced overall productivity, and inferior technological characteristics of the produced pig iron.
This article discusses the results of research on modeling alternative technologies for averaging agglomerate ore.

The article presents a digital processing algorithm for monitoring short-circuit currents in the power supply network. It is proposed to carry out control by calculating the rate of change of current. An algorithm based on a digital differentiating filter with suppression of high-frequency components has been developed. Based on the Fourier series, a non-recursive filter is formed, the characteristics of which are improved using the Lanczos smoothing method. It is proposed to use a recursive filter transformed from a non-recursive one using the B.L. Ho algorithm to save processing. The algorithm is easily implemented as programs for microprocessor systems. A filter based on an analog prototype is presented. A simulation of the short circuit process has been carried out.
