Authors: Kou Renke , Wang Chunping , Huang Fuyuan , Yu Ying , Peng Zhenming , Fu Qiang
Published: March 2023

It is a challenging task to separate infrared small targets from complex backgrounds quickly and accurately. With the development of deep learning, to effectively extract the features of infrared small targets, many algorithms use classic networks (VGG, UNet, or ResNet, etc.) as a backbone in the encoding phase. At the same time, various multiscale feature fusion modules, channel, and space attention mechanism fusion modules are designed. Although these designs are slightly helpful to the improvement of infrared small target detection accuracy, they will cause a significant increase in params and floating-point operations per second (FLOPs). To reduce the computational complexity, a lightweight infrared small target segmentation network (LW-IRSTNet) is proposed. The Depthwise separable-Atrous-Asymmetric-Atrous (DAAA) module is built by taking full advantage of the combination of depthwise separable, atrous and asymmetric convolution. The ablation experiment shows that the DAAA module plays an important role in improving segmentation accuracy and reducing params and FLOPs. To verify the accuracy, robustness, and computational complexity of LW-IRSTNet, 17 state-of-the-art networks are used as baselines for comparative analysis. The experimental results showed that the segmentation accuracy indexes (mIOU, F1, ROC) of LW-IRSTNet are all above or equal to the baseline best results on the five public datasets. Meanwhile, the network params are compressed to 0.16M and FLOPs to 303M, which is much lower than the baseline results. In addition, LW-IRSTNet is deployed on the Orange Pi 5 embedded platform. Through the ONNX framework, NPU acceleration and CPU multi-threaded resource utilization, the high-performance inference capability of LW-IRSTNet is realized, with FPS up to 50. A lot of comparative experimental results and the LW-ISTSNet inference model based on the Ptorch and onnx frameworks is published at https://github.com/kourenke/LW-IRSTNet.

Data generated from sources such as wearable sensors, medical imaging, personal health records, pathology records, and public health organizations have resulted in a  massive information increase in the medical sciences over the last decade. Advances in computational hardware, such as cloud computing, Graphical Processing Units (GPUs), and Tensor  Processing Units (TPUs), provide the means to utilize these data.  Consequently, many Artificial Intelligence (AI)-based methods have been developed to infer from large healthcare data. Here,  we present an overview of recent progress in artificial intelligence  and biosensors in medical and life sciences. We discuss the role  of machine learning in medical imaging, precision medicine,  and biosensors for the Internet of Things (IoT). We review the  most recent advancements in wearable biosensing technologies  that use AI to assist in monitoring bodily electro-physiological  and electro-chemical signals and disease diagnosis, demonstrating  the trend towards personalized medicine with highly effective, inexpensive, and precise point-of-care treatment. Furthermore,  an overview of the advances in computing technologies, such as  accelerated artificial intelligence, edge computing, and federated  learning for medical data, are also documented. Finally, we investigate challenges in data-driven AI approaches, the potential  issues that biosensors and IoT-based healthcare generate, and the distribution shifts that occur among different data modalities,  concluding with an overview of future prospects 
On enhancing Network Slicing Life-Cycle through an AI-native Orchestration Architecture
Authors: Moreira Rodrigo , Martins Joberto , de Oliveira Silva Flávio
Published: March 2023

Legacy experimental network infrastructures can still host innovative services through novel network slicing orchestration architectures. Network slicing orchestration architectures available in state-of-the-art have building blocks that structurally change depending on the problem they are trying to solve. In these orchestrators, life-cycle functions of network slices experience advances on numerous fronts, such as combinatorial methods and Artificial Intelligence (AI). However, many of the state-of-the-art slicing architectures are not AI-native, making heterogeneity and the coexistence and use of machine learning paradigms for network slicing orchestration hard. Also, using AI in a non-native way makes network slice management a challenger and shallow. Hence, this paper proposes and evaluates a distributed AI-native slicing orchestration architecture that delivers machine learning capabilities in all life cycles of a network slice. Carried experiments suggest lower error using distributed machine learning models to predict RAN resource consumption in slicing deployed over different target domains.
Antenna Setup for Future Joint Radar-Communications – Characteristics and Mounting Positions
Authors: Lübke Maximilian , Fuchs Jonas , Dubey Anand , Frank Martin , Franchi Norman , Lurz Fabian
Published: March 2023

The development of millimeter wave systems is driven by the strong trend toward new communications generations and especially by the emerging joint radar and communications design approach. Safety-critical applications like platooning or intersection assistance will significantly benefit from the combination of sensing and communications. While radar performs a channel measurement and thus, needs a wide field of view (especially in city/intersection scenarios), communications aims to minimize the interference for other not addressed receivers (e. g. in a platoon) by a focused antenna design. The proposed work extends the analysis of the influence of various antenna positioning for a typical automotive scene by taking also different characteristics (antenna gain, half power beamwidth, and sidelobe level) into account. Hereby, it is mandatory to investigate the communications and sensing performance simultaneously. The positions at the front bumper – typical for radar sensors – and especially at the left mirror convinced regarding the vehicular communications as well as the sensing behaviour. Applying focused antennas is promising, however, has also limits if the signals are not received out of the main beam but out of the sidelobes, resulting in a critical communications performance. Thus, beam steering is recommended to be applied in the future.

 
Zero-shot Transferable and Persistently Feasible Safe Control for High Dimensional Systems by Consistent Abstraction
Authors: Wei Tianhao , Kang Shucheng , Liu Ruixuan , Liu Changliu
Published: March 2023

Safety is critical in robotic tasks. Energy function based methods have been introduced to address the problem. To ensure safety in the presence of control limits, we need to design an energy function that results in persistently feasible safe control at all system states. However, designing such an energy function for high-dimensional nonlinear systems remains challenging. Considering the fact that there are redundant dynamics in high dimensional systems with respect to the safety specifications, this paper proposes a novel approach called abstract safe control. We propose a system abstraction method that enables the design of energy functions on a low-dimensional model. Then we can synthesize the energy function with respect to the low-dimensional model to ensure persistent feasibility. The resulting safe controller can be directly transferred to other systems with the same abstraction, e.g., when a robot arm holds different tools.  The proposed approach is demonstrated on a 7-DoF robot arm (14 states) both in simulation and real-world. Our method always finds feasible control and achieves zero safety violations in 500 trials on 5 different systems. 
Security-Enhanced Directional Modulation Symbol Synthesis using High Efficiency Time-Modulated Arrays

Published: March 2023

Time-modulated arrays (TMAs) have been found useful to construct directional modulation (DM) transmitters, offering physical-layer security. Two issues, however, exist in conventional TMA DM, which are high power loss and generation of mirror harmonic frequency signals that may compromise wireless security. In this letter, we propose to construct DM transmitters using a high efficiency TMA. By carefully designing the time sequences of the selected phase shifters, the DM symbols modulated upon multicarrier can be synthesized with suppressed mirror harmonic frequencies. It is shown that the proposed TMA DM transmitters here enjoy feeding network efficiency of 100%, and the transmit DM symbols can be synthesized at a pre-selected frequency only, significantly enhancing security performance. The effectiveness of the proposed scheme is validated via bit error rate (BER) simulations. Meanwhile, The TMA DM also can be used as a potential technique for the integrated sensing and communication (ISAC).

The Covid-19 pandemic has been around for more than two years. One of them is Indonesia. School closures are one of the consequences of Covid-19 for the world of education. In the face of the Covid-19 pandemic, educational institutions such as schools carry out online or online learning processes (in the network) as an effort to stop the spread of the Covid-19 virus. After approximately 2 years of face-to-face learning held again, of course it will cause changes in the learning process and there will be adjustments to the new habits of students after online learning. In addition, one of the impacts that affect learning is the enthusiasm and motivation of school students to learn. During the pandemic, of course, online learning that is less effective and maximally makes a significant impact on the way students learn, who tend to only be given assignments, of course, causing boredom, which can certainly have an impact on other aspects. The return of students' enthusiasm and motivation to learn does not just happen in a short period of time, but takes a long time because of a new adaptation process with new learning activities. All elements involved in the student learning process, both in the school and home environment, must all be interrelated and support one another.

Представлены основные соотношения для расчета расстояний между излучателями для разных структур антенных решеток. Приводится сравнение расстояния между элементами в прямоугольной сетке с радиальной по критерию равного коэффициента заполнения антенного полотна излучающими элементами, при этом площадь прямоугольного раскрыва равна площади круглого. Для этого была показана зависимость шага для радиальной сетки расположения излучающих элементов в узлах антенной решетки, рассчитанная при заданном шаге между излучателями в прямоугольной сетке. Показано отличие двух структур плоских антенных решеток по максимальному боковому лепестку. Сравнение проводилось для структур антенных решеток, содержащих на раскрыве различное количество элементов: 25 и 145. Отмечено, что диаграмма направленности антенной решетки с радиальной структурой имеет более равномерное распределение боковых лепестков в различных плоскостях обзора φ, по сравнению с прямоугольной. При этом продемонстрированно, что наивысший боковой лепесток в радиальной структуре никогда не достигает уровня 0 дБ

in this paper, studies of the position and level of the lateral diffraction maxima of the radiation pattern in a flat antenna array with a radial grid arrangement of radiating elements are carried out. The basic relations for calculating the distances between emitters for different antenna array structures are presented. A comparison of the distance between elements in a rectangular grid with a radial one is given, according to the criterion of equal filling factor of the antenna web with radiating elements, while the area of a rectangular opening is equal to the area of a round one. To do this, the step dependence for the radial grid of the location of the emitting elements in the nodes of the antenna array was shown, calculated at a given step between the emitters in a rectangular grid. The difference between the two structures of flat antenna arrays along the maximum side lobe is shown. The comparison was carried out for antenna array structures containing a different number of elements on the opening: 25 and 145. It is also noted that the radiation pattern of an antenna array with a radial structure has a more uniform distribution of side lobes in different viewing planes φ, compared with a rectangular one. At the same time, it is demonstrated that the highest lateral lobe in the radial structure never reaches the level of 0 dB

исследуется методика синтеза полосовых фильтров в SIW-исполнении на основе E- и H-диафрагм. Реализация полосового фильтра предполагает формирование резонансных полостей в канале волновода. Для синтеза полосовых фильтров сгенерирована модель SIW-волновода с критической частотой 8 ГГц, после чего в канале сформированы резонансные полости на основе диафрагм. Для установления размеров диафрагм сформированы модели на основе прямоугольного волновода с воздушным заполнением и полосой рабочих частот, увеличенной с учётом неединичной относительной диэлектрической проницаемости среды. В соответствии с принципом электродинамического подобия получены оценочные частоты полос пропускания SIW-фильтров. После формирования полной модели SIW полосовых фильтров установлено, что удается сохранить высокие показатели передачи в полосе пропускания и подавления в полосе задержания. Смещение частоты среза от предполагаемого значения, полученного на основе принципа электродинамического подобия, составило порядка 0.5 ГГц. Представленные результаты свидетельствуют о том, что волноводные полосовые фильтры могут быть эффективно реализованы в SIW-исполнении, а рассмотренная методика синтеза фильтров по SIW-технологии вполне пригодна для практического использования. Для коррекции смещения полосы рабочих частот и ширины полосы пропускания показаны предыскажения указанных показателей на начальных этапах синтеза

the article studies the possibility of forming a band-pass filter in SIW design based on E- and H-diaphragms. Formation of a bandpass filter is based on the principle of the appearance of resonant cavities in the wave-water channel. To form a bandpass filter, an SIW waveguide model with a critical frequency of 8 GHz was created, after which resonant cavities were formed in the channel using diaphragms. To determine the dimensions of the diaphragms, models of a rectangular waveguide with air filling and a range of operating frequencies increased by the root of the dielectric constant of the medium times were obtained. By applying the principles of electrodynamic similarity, estimated passband frequencies for the SIW filter were obtained. After the formation of the full SIW model of the band pass filter, it was found that it is possible to maintain high transmission in the passband and rejection in the stopband. The frequency shift from the target value obtained using the electrodynamic similarity method was about 0.5 GHz. The above results show that waveguide bandpass filters can be implemented in the SIW design, which allows for the selection of electromagnetic waves, which will expand the range of devices in which the use of SIW waveguides is possible

проведено экспериментальное распознавание человеком-оператором оптико-электронного средства на экране монитора изображений различных объектов и символов при искажении их пространственно-частотной фильтрацией (имитирующей «размытие» изображения оптической системой с учетом ее конечной угловой разрешающей способности) и случайным коррелированным (некоррелированным) шумом (имитирующим шум приемного тракта, а также возможные случайные искажения и помехи на трассе наблюдения). Во время проведения эксперимента для оценки степени искажения изображений объектов и символов, а также для исследования потенциальной возможности их распознавания использовался показатель, характеризующий сходство формы изображения объекта с его эталоном, на основе второй производной их корреляционного интеграла. На основе анализа и обработки полученных экспериментальных данных о вероятности распознавания человеком-оператором на экране монитора изображений различных объектов и символов при их искажении установлена зависимость вероятности распознавания от степени искажения изображений объектов и символов и получено аналитическое выражение для численного расчета вероятности их распознавания. Использование описанного подхода позволяет решать задачу оценки эффективности распознавания человеком-оператором изображений объектов и символов, а также задачу обоснования требований к оптическим средствам и объектам наблюдения

an experimental recognition of images of various objects and symbols on the monitor screen by a human operator of an optoelectronic device was carried out when they were distorted by spatial-frequency filtering (simulating the "blurring" of the image by an optical system taking into account its finite angular resolution) and random correlated (uncorrelated) noise (simulating the noise of the receiving path, as well as possible random distortions and interference on the observation track). During the experiment, to assess the degree of distortion of images of objects and symbols, as well as to investigate the potential for their recognition, an indicator was used that characterizes the similarity of the shape of the image of an object with its standard, based on the second derivative of their correlation integral. Based on the analysis and processing of experimental data obtained in the article on the probability of recognition by a human operator on the monitor screen of images of various objects and symbols when they are distorted, the dependence of the recognition probability on the degree of distortion of images of objects and symbols is established and an analytical expression for numerical calculation of the probability of their recognition is obtained. The use of the described approach makes it possible to solve the problem of evaluating the effectiveness of recognition by a human operator of images of objects and symbols, as well as the problem of substantiating the requirements for optical means and objects of observation

рассматриваются два метода исследования характеристик диаграмм обратного рассеяния (ДОР) для самолетов пятого поколения: Lockheed Martin F-22A Raptor и Сухой Су-57. Для определения характеристик ДОР предлагается использование асимптотического моделирования объекта с получением полной картины эффективной площади рассеяния (ЭПР), блестящих точек, направлением распространения отраженных волн; экспериментального исследования с использованием ультразвукового радиолокатора. Проведенное исследование показывает, что применение современных методов разработки самолетов позволяет снизить ЭПР объекта, что подтверждается как полноразмерными моделями при моделировании, так и при экспериментальном исследовании масштабных моделей. Так как при экспериментальном исследовании использовался ультразвуковой локатор, то в соответствии с правилом электродинамического подобия были выбраны частоты, которые соответствуют волнам, которые облучали бы полноразмерную модель. Результаты исследования приводятся в виде диаграмм обратного рассеяния с шагом в 1 градус для моделирования и 10 для экспериментального исследования. Картины диаграмм обратного рассеяния имеют похожую форму, но присутствуют различия, которые вызваны меньшим шагом измерения при эксперименте, а также экспериментальные данные представлены в виде дБмВ вместо квадратных метров, так как не производился пересчет в значения эффективной площади рассеяния

the article discusses two methods for studying the characteristics of backscatter diagrams for the fifth generation military planes: Lockheed Martin F-22A Raptor and Sukhoi Su-57. To determine the characteristics of the monostatic scattering, it is proposed to use asymptotic modeling of the object to obtain a whole picture of the effective scattering area, bright points, and the direction of the reflected waves propagation. Experimental study using ultrasonic radar is also proposed. The study shows that the use of modern aircraft development methods can reduce the RCS of an object, which is confirmed both by full-size models in modeling and by experimental study of scale models. Since an ultrasonic locator was used in the experimental study, in accordance with the rule of electrodynamic similarity, frequencies that correspond to the waves that would irradiate the full-size model were chosen. The results of the study are presented in the form of backscatter diagrams with a step of 1 degree for simulation and 10 for experimental study. The patterns of backscatter diagrams have a similar shape, but there are differences that are caused by a smaller measurement step in the experiment, and the experimental data are presented in the form of dBmV instead of square meters, since no conversion to the values ​​of the effective scattering area was made

поставлен вопрос подробного описания областей теории электрической связи, распределение параметров в которых отличается от «обычного», наиболее часто встречаемого во всех областях науки распределения – гауссовского (нормального), приведены не только причины подобного отклонения от привычной картины, но и математическая формализация. Ввиду сложности рассмотрения вопроса в целом показывается только распределение Рэлея и, как вырожденный случай – распределение Райса. Помимо физических процессов описан применяемый математический аппарат из области математической статистики и высшей математики, введены применяемые термины, подготовлена теоретическая база, позволяющая погрузиться в рассматриваемую тематику даже слабо подготовленному читателю. В ходе исследования приводится общая информация о теории электрической связи, распространении радиоволн и статистической радиотехнике. Исследованы варианты принимаемых ЭМВ и особенности распределения их характеристик. Объектом исследования является распределение амплитудных и частотных характеристик принимаемых волн, предметом - особенности принимаемых волн с учетом искажения в канале связи. Тема исследования имеет междисциплинарный характер и предполагает привлечение источников как из сферы теории электрической связи, так и теории вероятностей и математической статистики

we raised the question of a detailed description of the areas of the theory of electrical communication, the distribution of parameters in which differs from the “usual” distribution most often encountered in all fields of science - the Gaussian (normal) distribution, not only the reasons for such a deviation from the usual picture are given, but also mathematical formalization. Due to the complexity of considering the issue as a whole, we shown only the Rayleigh distribution and, as a degenerate case, the Rice distribution. In addition to physical processes, we described the applied mathematical apparatus from the field of mathematical statistics and higher mathematics, the terms used are introduced, a theoretical base is prepared that allows even a poorly prepared reader to immerse themselves in the subject under consideration. The study provides general information about the theory of electrical communication, propagation of radio waves and statistical radio engineering. We investigated variants of received EMW and features of distribution of their characteristics. The object of the study is the distribution of the amplitude and frequency characteristics of the received waves, the subject is the features of the received waves, taking into account the distortion in the communication channel. The research topic is interdisciplinary in nature and involves the involvement of sources from both the theory of electrical communication and the theory of probability and mathematical statistics
