Między solidarnością a wykluczeniem. Nauczyciele jako grupa zawodowa w sytuacji kryzysu
Authors: Karwatowska Małgorzata
Published: February 2025

The author presents teachers as that professional group that has experienced serious crises over the past few years (the 2019 strike and the COVID-19 pandemic) that have had a significant impact on their integrity and being evaluated by society. In these difficult situations, teachers have been faced with many challenges and not easy decisions, which have resulted in, among other things, destabilization of the teaching process, disunity and lack of solidarity within the professional group. They also entailed a strong polarization of society (including parents and students), who represented far extreme views. The purpose of the undertaken study is to attempt to answer the question: Are teachers victims of the system, the pandemic or of themselves? The analyses referred to in the text proved that teachers are victims not only of the system, but also of the excessive expectations often placed on them. False generalizations (teachers perceived as oversensitive about themselves, despotic, shouty, infantile, intrusive, manifesting a lack of mutual respect) are not only detrimental to educators, but also contribute to creating barriers to interpersonal communication. Moreover, it turned out that in crisis situations that require “speaking with one voice,” teachers as a professional group did not quite pass the test of practicing such an important value as solidarity.
Teatr dobry na wszystko – między dydaktyką a glottodydaktyką polonistyczną
Authors: Wacławek Maria
Published: February 2025

Theatre provides many educational benefits. A new Polish educational reality encourages combining the teaching of Polish as a native language and as a foreign language. The author explains the importance of theatre education and the needs of learners with migration experience. Then she describes the work on preparing the adaptation and staging of Krzyżacy [The Knights of the Cross] by Henryk Sienkiewicz, adapted to the needs of foreigners learning Polish as a foreign language. The author hopes that describing the experience will become an inspiration for Polish teachers in primary and/or secondary schools to create their own theatre projects following the needs of their pupils – both Polish and foreign. It is important to act less schematically, creatively crossing the boundaries of the literary text. This frees the subjectivity of the participants in the educational process.

Authors: Showalter Nicholas E. , Hamel John M. , de Weck Olivier L. , Hastings Daniel E.
Published: February 2025

Recent growth in space activities has led to increased interest in on-orbit refueling and repositioning (OORR) systems. Despite this interest, limited analysis has been conducted to quantify their anticipated impacts. Using the Advanced Technology Roadmap Architecture, this work evaluates the state of progression of OORR systems by incorporating historical technologies, stakeholder relationships, and technical and financial modeling. The results of this analysis aim to inform future design considerations for OORR systems that are rooted in a novel dataset of historical, current, and future refueling and repositioning systems. To capture the client–servicer relationship of these technologies, a new method of developing and validating figures of merit (FOMs) based on adjoined client–servicer needs is introduced. This process identifies OORR-enabling technologies, expanded applications, projected maturation rates, and FOMs to quantitatively track technological progression. Historic client lifetime extension rates between 30 and 39% and timelines greater than 2 years to receive maneuverability servicing were found alongside projected fuel mass ratios of 46–54% and average costs of $277k–$290k per kilogram of fuel launched on servicing systems over the coming decade. Overall, it is shown that OORR technologies are in a phase of rapid development progress and offer prospective performance and financial benefits to on-orbit users.
Aerodynamic Evaluation of Static and Dynamic Stability Characteristics of Double-Delta Wings
Authors: Brody Nolan A. , Fagley Casey , Morris Craig
Published: February 2025

Vortex interactions and breakdown play a critical role in determining the static and dynamic stability of aircraft, particularly at high angles of attack. This study investigates the relationship between vortex interactions and aircraft stability characteristics, focusing on how chord ratio, angle of attack, and sideslip angle influence stability metrics. Utilizing force and moment measurements along with pressure-sensitive paint (PSP) for surface pressure distributions, the results show the effects of varying double-delta wing chord ratios at a target Mach number of 0.15. The stability metrics derived from force and moment measurements demonstrate directional stability improvements with increasing sideslip angle due to larger vortex-induced differential drag induced by advanced windward wing vortex breakdown. This asymmetric vortex breakdown was confirmed through PSP-measured surface pressure distributions. The study metrics revealed trend reversals in lateral stability due to the varying state of vortex systems on different models, and higher reduced frequencies, pitch rates, and chord ratios correlated with greater dynamic instability and sensitivity. This is attributed to the more rapid and extensive vortex breakdown associated with these higher parameters. These findings provide deeper insights into the flow physics governing high-alpha maneuvers, offering a foundation for future research, enhancing the design and performance of next-generation aircraft.
Data-Driven Event-Triggered Predictive Post-Impact Control of Space Robot with Uncertainties
Authors: Chaudhary Saurabh , Dubey Richa , Tripathy Niladri S. , Shah Suril V.
Published: February 2025

Satellite-mounted robotic systems play an important role in various on-orbit services. The present work focuses on controlling a multi-arm space robot in the post-impact phase under the presence of uncertainties, which may arise due to dynamical parameter variation, joint friction, and disturbances. This work proposes a Gaussian Process-based Model Predictive Control (GP-MPC) to achieve the desired motion by mitigating the effects of uncertainties. Whereas the GP helps in predicting uncertainties from collected data, the MPC provides control inputs subject to the cost function and constraints. Further, an event-triggered control strategy is employed to reduce the computational burden associated with GP-MPC. It uses a Chernoff-bound-based triggering threshold to decide the occurrence of events. The generated control inputs may disturb the base’s attitude, and reactionless manipulation is also presented as a special case to mitigate it. The analytical outcomes are verified through numerical simulations on a dual-arm planer space robot.
Aerodynamic Noise from Circular Cylinders Under Turbulent Inflow Conditions
Authors: Geyer Thomas F. , Lucius Andreas , Schneider Marc , Enghardt Lars
Published: February 2025

The aerodynamic noise generated by a circular cylinder in a subsonic crossflow is a classical problem in aeroacoustics, which has been investigated experimentally and numerically in the past. The presence of a turbulent inflow is known to have an effect on the generation of tonal noise due to vortex shedding, although the available experimental data are sparse. The present paper describes an experimental study on the noise generated by a set of circular cylinders in grid-generated turbulence conducted in an aeroacoustic wind tunnel facility. Acoustic measurements were performed using microphone array technology. The results show that the free stream turbulence broadens the spectral peak of the vortex shedding tones, especially for cylinders with a diameter that is small compared to the turbulent integral length scale. One key result of the study is that the turbulent inflow leads to an increase in the vortex shedding Strouhal number compared to the case with clean inflow as well as to an additional increase of the Strouhal number with Reynolds number. This trend can also be observed qualitatively in the velocity power spectral densities measured in the wake of a selected cylinder using hot-wire anemometry.

Published: February 2025

This study presents wall pressure sensors based on wall-flush Kevlar-covered cavities. The sensor dynamic response is characterized using a variety of acoustic and flow experiments, including a flow disturbance quantification performed using wall-parallel particle image velocimetry. Various sensor configurations are studied to understand the relation between cavity shape and Kevlar scrim on the sensor response. Using a localized excitation study, the sensor’s spatial sensitivity is characterized, and a mathematical model to estimate the wall pressure spectrum is presented. It is shown that these sensors have a well-defined, second-order dynamic response without grazing flow. Their performance in flow shows the disturbance to the flow below the measurement uncertainty, indicating no significant flow disturbance. Comparing measured data with the model estimates reveals close agreement, within [Formula: see text], and that discrepancy is accounted for by grazing flow effects and sensor spatial sensitivity.
Tip Vortex Effects on Rotor Aeroacoustics via Hybrid Blade Element Momentum Theory–Free Vortex Wake Prediction
Authors: Wang Zimo , Chen Qidong , Zhong Siyang
Published: February 2025

During rotor operation, wakes and tip vortices form and convect downstream, generating unsteady velocities on the blade surface, which act as significant noise sources. High-fidelity numerical simulations account for these effects but are computationally expensive, while the rapid predictions based on blade element momentum theory (BEMT) alone cannot capture the fluid mechanisms associated with tip vortex wakes. This paper presents a hybrid BEMT and free vortex wake (FVW) method to compute mean and unsteady flow variables on blade sections. The BEMT solver accommodates arbitrary flow directions, accounting for variations with the rotational phase angle, while the FVW models tip vortex dynamics with initial strength from BEMT computations. Unsteady airfoil theory is applied to compute time-varying loadings in inflight conditions, serving as noise sources for acoustic calculations. The method is validated with a benchmark rotor in hover and axial flow conditions, where wake correction alters thrust but has negligible noise impact. In inflight conditions, the FVW significantly improves prediction accuracy for blade passing frequency harmonics compared to BEMT alone. Near-field velocity and vortex structures also match high-fidelity simulations well. Application to a multirotor vehicle demonstrates the method’s potential for rapid and efficient noise estimation in low-altitude flight scenarios.
Investigation of Coaxial Surface Junction Thermocouples Under Different Materials on Thermal Measurement
Authors: Qi Li , Chen Hongchu , Yu Zhichao
Published: February 2025

Coaxial surface junction thermocouples (CSJTs) are commonly applied to transient thermal measurements. Based on the measurement principle of CSJT, one-dimensional analytical inversion is applied for obtaining surface heat fluxes. However, with the thermophysical properties difference between the wall material and CSJT, transverse thermal conduction occurs that leads to a measurement error of surface temperature by CSJT. Hence, conventional temperature data processing methods can lead to surface heat flux measurement error. Therefore, quantitative analysis of lateral structural heat transfer should be carried out in the junction region and the interface between the sensor and the wall. In this paper, the multidimensional transmission of heat between three types of CSJTs and wall material under transient and long duration was investigated by numerical simulations. And the derivation of the axisymmetric heat transfer government equation was obtained by the improved Crank–Nicolson discrete scheme. We found the best wall materials for thermal matching with E-, J-, and K-type CSJTs, respectively. And the stainless steel tube can maintain a stable heat flux curve within a certain period. The conclusions of this study offer practical guidance for the selection of wall material and design improvement of CSJTs.
Exploring tourists' intention to use smart tourism apps
Authors:   Universidad de La Laguna (España), David-Negre Tatiana , Gutiérrez Taño Desiderio ,   Universidad de La Laguna
Published: February 2025

This study investigates tourists’ intention to use apps when travelling and the factors that influence this intention. Although various studies have addressed the adoption of different technologies, how tourists approach technologies featuring smart destination functions has scarcely been studied. To study this area, we used a model based on the theoretical UTAUT2 model to understand the motivations behind the adoption of these apps. An online survey was conducted, resulting in 107 responses. We then tested our model using partial least squares structural equation modelling (PLS-SEM). The results suggest that outcome expectancy, habit, and facilitating conditions positively influence intention to use tourism apps. However, we were unable to confirm that effort expectancy, social influence, hedonic motivation, and the price/value relationship affect intention to use. At the end of the article, we discuss possible practical implications for developers and tourist destination managers

Published: February 2025

Relationships between members of a social/cultural group have been a topic of study for decades, with shame being one main feeling generated from non-compliance with previously established norms, which may vary from one society and generation to another. Due to a fall in ethical values, the culture of complaints and the exchange of opinions, shame seems to have been diluted in several industries, especially hospitality, and therefore it has generated benefits for the client and negative feelings for the hotelier. The aim of this study was to analyse the close relationship between having no shame and calling someone shameless. The research instrument used for data collection was a questionnaire based on the Likert-scale with 5 response possibilities in relation to the hypotheses of this study and questions sent to a Whatsapp group. Through the method based on the structural equation model (SEM-PLS), a total of 116 responses from hoteliers were collected. The results revealed that not being ashamed to request extra services benefits guests, however it generates a negative word among hoteliers when referring to guests.

Authors: Nainggolan Rexon
Published: February 2025

ABSTRACT
The primary aim of this study is to illustrate how logarithmic calculation and equation can effectively replace traditional table usage and interpolation techniques in time value of money calculations. It proposes the application of algorithmic computation to calculate the interest rate and period when the future value and present value are known. It developed and formulated two primary equations utilizing an algorithmic approach as an alternative to the conventional reliance on financial tables and linear interpolation prevalent in the existing literature. The two methods are validated and substantiated upon reevaluating the fundamental time value of money calculation, yielding far more precise results than the traditional method. The measurement can also be utilized in the statistical realm to compute the compounded average yearly growth or growth period when other parameters are available.
ABSTRAK

Проведены совместные измерения осадков радиолокационными и наземными методами в районе г. Лабинска на базе Краснодарской военизированной службы на основе развёрнутой сети осадкомеров, входящих в состав автоматических метеостанций Davis Vantage Pro 2. Выполнен анализ измерений осадков двух радиолокаторов: «МРЛ-5» с длиной волны 10 см и радиолокатором «ДМРЛ-С» с длиной волны 5, 3 см. Установлено, что с учётом расстояния между радиолокаторами и наземной сетью приборов 122 км средняя относительная ошибка измерения суммарных осадков достигает 51,36 и 58,0 % для длины волны 5, 3 и 10 см соответственно.

Introduction. When employing any method to measure precipitation, the primary goal is to acquire representative data for the studied area. Hence, careful consideration of the precipitation gauge's location, type, and its ability to mitigate losses from evaporation and wind effects is crucial. In this study, the authors aimed at assessing the accuracy of measurements using radar systems. Technique and conditions of the experiment. Radar enables the observation of precipitation area positions and movements. The study utilized the Doppler meteorological radar DMRP-C, dual-wavelength meteorological radar MRL-5, and a precipitation gauge within the automated weather station Davis Vantage Pro 2. These instruments were positioned in close proximity at the Stavropol Air Force Base in the city of Stavropol, with a distance of 170 meters between them. In the Labytnangi area, near the Krasnodar Air Force Base, a network of precipitation gauges was deployed, with a distance of 122 kilometers between the radars and the ground instrument network. Findings.The study examined five days with varying intensities of rainfall. The average relative error in measuring total precipitation was 51.36% and 58.00% for wavelengths of 5.3 cm and 10 cm, respectively. The higher measurement error at 10 cm is attributed, in our view, to the insufficient calibration of the MRL-5 radar at the Stavropol Air Force Base, primarily designed for active hail impact. Additionally, the MRL-5's larger probing pulse volume at such a distance from the precipitation zone contributes to increased measurement error. Conclusion. Future efforts should focus on optimizing the arrangement of hardware devices (radars and ground-based instruments), conducting thorough radar calibration, and exploring more appropriate coefficients in the I-Z relationship to minimize precipitation measurement errors.

На основе изучения более 50 публикаций выявлены и обобщены методы и модели, которые обычно используют авторы на различных континентах для прогнозирования дорожно-транспортных происшествий и разработки технологий по снижению их риска. Проанализированы результаты прогнозирования на основе моделей двумерной конволюционной (свёрточной) нейронной сети, долговременной кратковременной памяти, оптимизационных моделей, с открытым исходных кодом, рекуррентных блоков, роя частиц, графовой нейронной сети, классификации дерева решений машинного обучения, статистической модели и др., а также с использованием различных методов и показателей: время обработки, точность обработки, точность и полнота данных, ¥1-оценка, область под ROC-кривой, кривая точности воспроизведения, статистика каппа Коэна, средняя абсолютная ошибка. Выделено семь типов недостатков нейросетевых методов и моделей прогнозирования дорожно-транспортных происшествий, которые не снижают интенсивности исследований как в направлении применения различных моделей и методов, так и в создании новых. Сделано предположение, что в ближайшем будущем появятся специальные карты прогнозов вероятностей дорожно-транспортных происшествий по всем дорогам и перекрёсткам всех стран мира, по аналогии с существующими ныне географическими картами и электронными навигаторами.

Based on the study of more than 50 publications, methods and models that are commonly used by authors on different continents for predicting road accidents and developing technologies to reduce their risk are identified and summarized. Prediction results are analyzed on the basis of two-dimensional convolutional (convolutional) neural network models, longterm short-term memory, optimization models, open-source, recurrent blocks, particle swarm, graph neural network, machine learning decision tree classification, statistical model, etc., as well as using different methods and indicators, as well as using various methods and indicators: processing time, processing accuracy, data accuracy and completeness, F1-estimation, area under the ROC curve, reproduction accuracy curve, Cohen's kappa statistic, mean absolute error. Seven types of shortcomings of neural network methods and models of traffic accident prediction are identified, which do not reduce the intensity of research both in the direction of applying different models and methods and in creating new ones. The assumption is made that in the near future there will be special maps of forecasts of road accident probabilities for all roads and intersections of all countries of the world, by analogy with the currently existing geographical maps and electronic navigators.

Structural motifs based on tetraphenylmethane have drawn substantial interest as components of molecular electronic circuits, self-assembled monolayers, and three-dimensional polymers. However, the broad utility of such motifs is limited, for example, by the broken conjugation though the central, sp3-hybridized, carbon or silicon atom(s). To enrich their functionality, we reason the central atom could be exchanged for a transition metal to improve electronic coupling between the 𝜋-conjugated substituents and impart reversible redox properties. In evaluating this hypothesis, here we probe single-molecule junctions comprising oligoaryl wires with tetrahedral osmium(IV), silane, or methane centers. Surprisingly, we find that transport through junctions formed from the intact molecules in a non-polar, inert solvent appears largely independent of the central atom identity. In contrast, the conductance of junctions comprising an osmium(IV) wire can be modulated in an electrochemical environment by a factor of 47, to values 80× higher than for a silane analogue, by opening the bias window asymmetrically about the electrode Fermi level (EF). These measurements also indicate that such compounds can undergo in situ reactions that result in junctions comprising their dissociated oligoaryl arms, linked by chemisorbed Au-C(sp2) contacts. Our experimental results are supported by first principles calculations, which predict the osmium(IV) wires are substantially more conductive than the organic analogues due to their delocalized and well-coupled frontier orbitals with energies close to EF. This work highlights the promising potential of transition metal tetraaryl complexes as isotropic building blocks for functional circuits and extended materials, while opening avenues for further studies to enhance the connection between experimental observations and theoretical calculations.
