Metrological Aspects of Pulsed Optical Tomography of Micro-Objects of Nuclear Fuel

Optoelectronics, Instrumentation and Data Processing. 2021. Vol. 57. No. 3. P. 257–264.
Baibikova T., Domoratsky E.

The developed and testedmethods of dynamic control ofmicro-objects(MOs) of nuclear
fuel, based on the reconstruction of spatial geometric characteristics of MOs along the contours of
two-dimensional shadow projections, are considered. To describe the dimensions of the MOs, the
overall dimensions and the average projected diameter are chosen, and their shape is described using
the nonsphericity coefficient, which is defined as the ratio of the maximum overall size of the object
to its minimum overall size. Metrological characteristics of control methods are given.

Effects of Elevation Changes and Multilevel Structures on Vehicular Signal Propagation
Stepanyants V., Andrey V. Fizulin, Chibirov A. et al., FUTURE TRANSPORTATION 2026 Vol. 6 No. 5 Article 225
Reliable Vehicle-to-Everything (V2X) evaluation requires propagation models that represent terrain and multilevel infrastructure. Most integrated vehicular simulators still rely on planar models, but the magnitude of the resulting bias is unclear. This study quantitatively compares flattened two-dimensional (2D) and terrain-aware three-dimensional (3D) variants of three scenarios using identical Sionna RT settings. The pipeline combines OpenStreetMap ...

Automated Ranking of Soybean Plots from Close-Range RGB Video via Depth Filtering and Point-Based Counting
Groshev Maksim, Rybakov Petr, Teterin N. et al., Sensors 2026 Article 6171
Manual assessment of soybean yield components, such as pod number, is laborious, time-consuming, and subjective. Existing computer-vision approaches based on object detection or instance segmentation perform poorly on close-range RGB imagery of soybean canopies due to severe occlusions, ambiguous plant boundaries, and the high cost of bounding-box annotation. To address these challenges, we propose a ...

Modeling weather-resilient laser communication: PPM performance with SNSPD in satellite links
Merzlinkin V., Khmelev A. V., Севрюков Д. О. et al., St. Petersburg Polytechnical University Journal: Physics and Mathematics 2025 No. 3 P. 205–209
Laser communication using satellites represents a promising avenue for data transmission in geographically distant areas without advanced infrastructure. This approach is characterized by its high transmission rate and low power requirements, providing substantial benefits over optical fiber and radio communication. However, the optical channel should exhibit greater transparency for light transmission, resulting in a severely restricted application of this technique for information ...

Quantum key distribution via satellites enables the technology to be applied attranscontinental scale; nevertheless, in contrast to fiber systems, using a free-space opticalcommunication channel presents certain extra technological obstacles. The contribution of theacquisition, pointing and tracking system’s operation to the potential quantum bit error valueis investigated in this research.

A satellite-constellation based global quantum network could allow secure quantum communication between remote users worldwide. Such a constellation could be formed of micro- or even nanosatellites, which have the advantage of being more cost-effective than larger expensive spacecrafts. At the same time, the features of quantum communication impose a number of technical requirements that are more difficult to meet when ...

Инкрементальный метод обновления многомерного куба по неупорядоченному потоку событий журналов информационных систем
Zykov S. V., Уфимцев Г. А., Моделирование, оптимизация и информационные технологии 2026 Т. 14 № 8 С. 1–13
Информационные системы формируют большие объёмы событийных журналов, которые используются для анализа работы приложений и сервисов. При этом события могут поступать в аналитический контур позже момента их фактического возникновения и не в исходном порядке. Такая рассинхронизация приводит к ошибкам при построении агрегированных временных показателей, а регулярный полный пересчёт многомерного аналитического куба требует значительных вычислительных затрат. Целью ...

Enhancing Boundary Stability in Decision Trees and Random Forests: A Weighted Sample Duplication Approach
Konstantinov A., Elizarova Anastasiya P., Utkin L., Computing, Telecommunications and Control 2026 Vol. 19 No. 1 P. 16–25
Decision trees and their ensemble extensions, such as random forests, are widely used as classification models due to their simplicity and interpretability. However, in many real-world tasks where class labels overlap in the feature space, standard decision trees rely on hard splits that create fragile decision boundaries. In these regions, small perturbations in the input ...

Bayesian Adaptive Sparse Copula
Prokhorov A., Burda M., Journal of Computational and Graphical Statistics 2026 P. 1–13
Bayesian nonparametric density estimation procedures are typically based on single-scale priors, such as Dirichlet process mixtures. Alternative multiscale density priors built on decision trees have many well-known advantages, including the ability to characterize abrupt local changes and to provide an estimate with a desired level of resolution. Despite their theoretical appeal, multiscale methods have typically ...

Ryumina E., Aksenov A., Сысоев Д. С. et al., IEEE Computer Society, 2026.
Ambivalence/hesitancy recognition in unconstrained videos is a challenging problem due to the subtle, multimodal, and context-dependent nature of this behavioral state. In this paper, a multimodal approach for video-level ambivalence/hesitancy recognition is presented for the 10th ABAW Competition. The proposed approach integrates four complementary modalities: scene, face, audio, and text. Scene dynamics are captured with ...
