представлена методика на искусственной основе нейронной сети для настройки оптимальных параметров пропорционально-интегрально-производного (ПИД) управления, позволяющая повысить эффективность управления траекторией движения беспилотных летательных аппаратов (БПЛА). Эта система управляется тремя различными структурами ПИД-регулирования для движений по крену (Roll), тангажу (Pitch) и рысканью (Yaw). Таким образом, адаптация БПЛА к линейным параметрам ПИД облегчается за счет использования нелинейных поведенческих параметров при обучении нейронной сети. Для этой цели моделирование полета системы летающего БПЛА выполнялось с 200 различными случайно определенными комбинациями параметров ПИД в среде моделирования Mission Planner, и набором данных о местоположении, входных данных и ПИД-параметров при создании выходного сигнала. Моделирование, выполненное на траектории, используемой в качестве контрольной при создании набора данных, показывает, что изменение ПИД-параметров управления рысканьем не вызывает существенного изменения ошибки траектории. Набор данных, полученный для настройки крена и тангажа, используется для моделей, разработанных с использованием нейронной сети прямого и обратного распространения, которая часто используется для определения оптимальных параметров усиления ПИД
this article presents a technique based onan artificial neural network for configuring optimal parameters of proportional integral derivative (PID) control,which allows to increase the efficiency of controlling the trajectory of unmanned aerial vehicles (UAVs). This system is controlled by three different PID control structures for Roll, Pitch and Yaw movements. Thus, the adaptation of UAVs to linear PID parametersis facilitated by the useof nonlinear behavioral parameters in neural network training. For this purpose, flight simulation of the flying UAV system was performed with 200 different randomly determined combinationsof PID parameters inthe Mission Planner simulation environment, and a set of locationdata, both input data and PID parameters when creatingthe output signal. The simulationperformed on the trajectory used as a control when creatingthe dataset shows that changing the PID parametersof the yaw control does not causea significant change in the trajectory error.The data set used to adjustthe roll and pitchis used for models developed using a forward and backward propagation neural network, which is often used to determinethe optimal parameters of PID amplification
FREE-SPACE OPTICAL COMMUNICATION LINE USING FORWARD ERROR CORRECTION CODING
Authors: Краснов Р.П. 
Published: September 2024

в связи с постоянным ростом объема передаваемых данных и высоким спросом на пропускную способность абонентских каналов в качестве широкополосной технологии «последней мили» может выступать атмосферная оптическая линия связи (АОЛС). Высокая спектральная и информационная эффективность по сравнению с радиочастотными линиями ухудшается за счет воздействия атмосферных эффектов в канале связи, в том числе и за счет атмосферной турбулентности. Для повышения качества связи предложено совместное использование методов помехоустойчивого кодирования и ортогонального частотного разделения каналов (OFDM). В статье рассмотрена система атмосферной оптической связи OFDM-типа, в которой для сигналов на поднесущих использовалась бинарная фазовая манипуляция (BPSK). Турбулентный атмосферный оптический канал описывался статистической моделью экспоненциального распределения Вейбулла. В качестве методов помехоустойчивого кодирования рассмотрены сверточные коды, коды Рида-Соломона и турбо-коды. Результаты показывают, что помехоустойчивые коды повышают качество связи системы передачи. Показано также, что турбо-коды значительно улучшают возможности коррекции ошибок по сравнению с другими методами в тех же условиях турбулентности и протяженности линии связи
due to the constant growth in the volume of transmitted data and the high demand for the capacity of subscriber channels, an free space optical communication line (FSO) can act as a “last mile” broadband technology. High spectral and information efficiency compared to radio frequency lines is at the same time deteriorated by atmospheric effects in the communication channel, including atmospheric turbulence. To improve the quality of communication, the joint use of noise-resistant coding and orthogonal frequency division (OFDM) methods has been proposed. The article discusses an OFDM-type atmospheric optical communication system in which binary phase shift keying (BPSK) was used for subcarrier signals. Turbulent atmospheric optical channel was described by a statistical model of exponential Weibull distribution. Convolutional codes, Reed-Solomon codes and turbo codes considered as noise-resistant coding methods. The results show that noise-resistant codes improve the communication quality of the transmission system. It is also shown that turbo codes significantly improve error correction capabilities compared to other methods under the same turbulence and link length conditions

Published: September 2024

Abstract: This study delves into the meaning behind visual elements and the significance of using photographic visuals in the cover of Orang Asli books based on Semiotic analysis, which is one of the areas of meaning study besides Semantics. In pursuing this aspect, two research objectives are outlined: to elucidate the photographic visuals on the covers of Orang Asli books based on Semiotic theory and to analyze the significance of using photographic visuals on the covers of Orang Asli books. This study applies Peirce's Semiotic analysis theory (1839-1914) as the main framework for the research data on four Orang Asli books investigated. The data collection and analysis process employs library methods, through material selection, survey forms, and document analysis. Findings indicate that the technique of using photographic visuals in Orang Asli book covers is more effective in capturing readers' attention because it portrays the reality or authenticity of the community's civilization. Additionally, the findings show that there are four main interests in photographic visuals that are more relevant for use: providing information, attracting attention, explaining concepts, and facilitating the audience in distinguishing book categories in the market.

Abstract: The advent of the COVID-19 pandemic has ushered in a new educational paradigm, initially exerting a negative impact on the mental well-being of students globally, including those enrolled in Malaysian universities. It is noteworthy that conventional, face-to-face learning at Universiti Teknologi MARA resumed in September 2022, which directly forced students’ transition from virtual learning during the pandemic to physical learning post pandemic. Consequently, this research project was undertaken with the objective of assessing the perceived stress levels among students pursuing a Diploma of Pharmacy at Universiti Teknologi MARA Cawangan Pulau Pinang (UiTMCPP) Bertam Campus. The study also explored into the origins of stress, encompassing both academic and non-academic factors, which students encountered in the post-pandemic era, as well as the strategies they employed to manage this stress. Data for this study were collected from 220 students through an online questionnaire, which incorporated the Perceived Stress Scale (PSS) to gauge their perceived stress levels, inquiries pertaining to academic and non-academic stressors, and investigations into the methods they adopted for stress management. Data from completed questionnaires were recorded into SPSS version 26 software for analysis. The outcomes of this research project revealed that a majority of the students reported experiencing a moderate level of stress. In summary, this study provides insights into the challenges confronted by Diploma of Pharmacy students at UiTMCPP Bertam Campus, with a specific emphasis on their perceived stress levels, the factors contributing to their stress, and the coping mechanisms they employ. These findings offer valuable information concerning the mental health of students in this context and may serve as a basis for devising strategies to support their well-being during these demanding circumstances.

Imperial Residues and the Birth of the Russian Federation: Maternal Care, Racialization and Economic Migration in <em>Ayka </em>and<em> Mama</em>
Authors: Lee Sophie 
Published: September 2024

Taking as its objects of study two contemporary films, Sergei Dvortsevoy’s 2018 Ayka and Anastasia Borisova’s 2019 film Mama, this article considers the vicissitudes of life as a female economic migrant and young mother in Moscow, with Mama representing the internal migration of its main protagonist from Sakha (known also as Yakutia) and Ayka the experience of a new mother from Kyrgyzstan. Both films engage the themes of pregnancy, childcare and racialised labour within post-Soviet Moscow, and they do so in analogous ways, each employing a documentary style that we might see as gesturing towards the ‘ethnofictions’ of Jean Rouch. Central to my inquiry is that both Ayka and Iye appeared at a time when pronatalist policies were actively being pursued within the Russian Federation, as part of the highly conservative agenda of V.V. Putin, and yet the dire material conditions of the films’ migrant heroines leave them unable to fully ‘assent’ to their new maternal roles. My article considers each film’s attempt to document the unequal access to postpartum care in Russia’s metropolis and draws upon theories of cinematic spectatorship to ask whether ‘intersectional’ Russophone films can transcend the violence of voyeurism and play an active role in feminist advocacy.
Gaussian Process Models Impact the Inferred Properties of Giant Planets around Active Stars
Authors: Tran Quang H. , Bowler Brendan P. 
Published: September 2024

Abstract
The recent development of statistical methods that can distinguish between stellar activity and dynamical signals in radial velocity (RV) observations has facilitated the discovery and characterization of planets orbiting young stars. One such technique, Gaussian process (GP) regression, has been regularly employed to improve the detection of a growing number of planets, but the impact of this model for mitigating stellar activity has not been uniformly analyzed for a large sample with real observations. The goal of this study is to investigate how GPs can affect the inferred parameters of RV-detected planets. We homogeneously analyze how two commonly adopted GP frameworks, a GP trained on RVs alone and a GP pretrained on photometry and then applied to RVs, can influence the inferred physical and orbital parameters compared to a traditional Keplerian orbit fit. Our sample comprises 17 short-period giant planets orbiting stars that exhibit a broad range of activity levels. We find that the decision to adopt GPs, as well as the choice of GP framework, can result in variations of inferred parameters such as minimum planet mass and eccentricity by up to 67% and 95%, respectively. This implies that the method for modeling stellar activity in RVs of young planet-hosting stars can have widespread ramifications on the interpretation of planet properties including their masses, densities, circularization timescales, and tidal quality factors. When mitigating stellar activity with GPs, we recommend carrying out comparative tests between different models to assess the sensitivity of planet physical and orbital parameters to these choices.
Entrapment in CO2 and H2O Ices: Impact of Ice Matrix Thickness
Authors: Pesciotta Cara , Simon Alexia , Rajappan Mahesh , Öberg Karin I. 
Published: September 2024

Abstract
The volatile inventories of planets depend on the precise partitioning of different volatiles between the gas and solid phases across the planet birth disk. For the case of hyper-volatiles (e.g., CO, N2, and noble gases), the partitioning also depends on how efficiently they are trapped into less volatile ice matrices. The thicknesses of these ice matrices can range from a few molecular layers to macroscopic bodies, and in this study we explore how entrapment efficiency depends on the ice thickness between tens of nanometers and a few micrometers (∼50–3000 monolayers, ML). We carry out a series of temperature-programmed desorption (TPD) experiments on H2O:CO and CO2:CO mixtures with 5:1 and 15:1 matrix-to-CO mixing ratios. Entrapment efficiencies range from 41% to 64%, with higher entrapment efficiencies for the more dilute ices. Surprisingly, we find no significant difference in entrapment across the studied ice thicknesses for either H2O or CO2 ice matrices. Complementary TPD experiments with the additional hyper-volatiles N2 and Ar see a similar trend with ice thickness. We speculate that these results may be due to surface topography such as cracks that lead to hyper-volatile escape from deep ice layers. In either case, these experiments show that entrapment in microscopic ices is relatively insensitive to ice thickness (above ∼50 ML). In protoplanetary disks we therefore expect efficient entrapment in icy grains of a range of grain sizes.
