Blind source separation algorithm for noisy hydroacoustic signals based on decoupled convolutional neural networks

Wireless communication technology has been widely used in marine engineering, marine ranching and Marine environmental monitoring. However, structural redundancy and functional confusion exist in applying neural networks in signal separation technology in underwater communication environments, which can result in a slower rate of signal separation and lead to confusion of parameters during transfer learning. Based on this, an end-to-end, internal functionally structured decoupled neural network (D-CNN) blind source separation (BSS) model is proposed in this paper, which can realize a neural network BSS algorithm with a well-defined structure and function. The one-dimensional convolutional neural network layer is used in algorithm to automatically extract observed signal's features, based on the features, and there are two generation modules of separation matrix and scaling coefficients. Then the two modules can be used to separate the observed signal and adjust the signal coefficients to obtain the separated signal. Finally the transfer learning technique is used to generalize the model, which reduces the transfer cost of the model in different application scenarios. Experimental results show that when the communication distance is set to 0.02 km–2 km, the MSE of independent signal and related signal can be reduced by 14.24% and 14.95% respectively compared with the nearest Neural FCA algorithm. The results prove that the proposed algorithm can accurately estimate the source signal and improve the signal reception quality.

A deep reinforcement learning based distributed multi-UAV dynamic area coverage algorithm for complex environment

Dynamic area coverage algorithm is often used in multiple unmanned aerial vehicle (multi-UAV) systems to realize searching or monitoring an area of interest (AOI). Improving coverage efficiency is one of the important research issues of dynamic area coverage. In this paper, we propose a distributed dynamic area coverage algorithm based on a reinforcement learning (RL) algorithm to enhance the coverage efficiency in complex application environments. A coverage information fusion based discrete soft actor–critic algorithm (herein FDSAC) is proposed to solve the non-stationary problem of RL algorithm in area coverage task under the communication constraint environment. Considering the equivalence of UAVs in the area coverage tasks, we introduce a multi-UAV cooperative learning method for FDSAC by sharing the strategy and experience of the UAVs to accelerate the learning speed of FDSAC in multi-UAV system. With the FDSAC algorithm, the UAVs can intelligently select the best coverage points and achieve almost optimal coverage point planning for the entire coverage process. In addition, we also provide a coverage point adjustment method based on the distribution of obstacles to enable the proposed algorithm adapt to obstacle environments. The experimental results demonstrate that the proposed algorithm can efficiently complete the area coverage task in complex communication and stochastic control noise environment. The good scalability, environment adaptability, and practicality of our algorithm have been also confirmed in different complex environments of different experimental platforms.

Visible scientists in digital communication environments: An analysis of their role performance as public experts on Twitter/X during the Covid-19 pandemic.

An optimization scheme of data link security transmission based on mobile edge computing

For the past few years, the security of data transmission links has been increasingly valued. However, with the increasing requirements for the security performance of data transmission links, how to cut the cost of upgrading while improving security has become a serious challenge. In response to the issue of ensuring low-cost and secure data transmission in wireless communication environments with eavesdroppers, this article innovatively starts with idle roadside units and studies how to incentivize roadside units to transmit interference power to interfere with eavesdroppers, thereby efficiently and economically improving the security performance of mobile user data transmission. Firstly, the impact of roadside unit transmission interference power on the security performance of data transmission links was analyzed by establishing a theoretical model; Then, this paper proposes a three-layer model consisting of ground user groups, eavesdropping users, roadside units, and UAVs equipped with mobile edge computing servers. In this model, by encouraging idle roadside units to send interference power, ground users are assisted to safely unload their own data to mobile edge computing servers. Meanwhile, considering the selfishness of idle roadside units, an improved algorithm based on simulated annealing algorithm is proposed to achieve the optimal mapping between ground users and idle roadside units. Finally, through the analysis of simulation results, this scheme can achieve the goal of reducing system costs while improving the security of data transmission.

Polarization and coherence properties of a partially coherent elegant Laguerre–Gaussian vortex beam in turbulent plasma

The analytical expressions for the cross-spectral density matrix elements of the partially coherent elegant Laguerre–Gaussian (eLG) vortex beam propagating through anisotropic turbulent plasma were derived based on the extended Huygens-Fresnel principle and used to study the changes in the polarization degree and the coherence degree of the partially coherent eLG vortex beam in the turbulent plasma. The numerical results show that the polarization degree of a partially coherent eLG vortex beam reaches a specific value (which is equal to the degree of polarization in the source plane) after a long propagation distance in the turbulent plasma. Moreover, this value is independent of the beam order, topological charge, correlation coefficient, wavelength of the source plane, anisotropy parameter, refractive index fluctuation variance, and outer and inner scales of the turbulent plasma. The results also show that with increasing distance, the coherence degree first decreases from unity and then oscillates around zero. However, this oscillation gradually disappears after traveling a long distance. Our results intuitively present the beam polarization and coherence properties through anisotropic hypersonic turbulence, which can be useful for optical communication in hypersonic turbulent environments.

Hardware implementation of a mirror array-based optical intelligent reflecting surface for VLC: prototype and experimental results

Faced with growing demands for high-speed and reliable communication systems, optical intelligent reflecting surfaces (OIRS) have recently attracted a lot of interest in visible light communication (VLC). With potential applications in a variety of scenarios, including indoor wireless communications and the Internet of Things (IoT), OIRS is expected to have a transformative impact on optical wireless communications. However, current research is predominantly theoretical, and the hardware implementation of OIRS is insufficient. Therefore, this paper introduces an OIRS prototype based on a mirror array, which is capable of adjusting the reflected lightwave by manipulating the orientation of individual OIRS units to realize an adjustable optical wireless communication environment. Additionally, a hardware platform with a configurable control system for OIRS-based VLC has been developed in this paper. Finally, experimental results demonstrate significant improvements in the amplitude of the received signal and the signal-to-noise ratio of the developed prototype, thereby verifying the enhancement of communication efficiency and the potential of practical OIRS deployment.

Strengthening collaborative learning in secondary school: Development and evaluation of a lesson-integrated training approach for transactive communication

BackgroundTransactive communication in collaborative learning environments occurs when students refer to their learning partners' ideas, build on them, and transform them into more elaborate ideas. This learning activity is essential for students to be able to benefit from collaboration, but they need scaffolding to produce transactive statements. From the teachers’ perspective, this intervention should take little effort. AimsWe developed and evaluated a lesson-integrated training in transactive communication for secondary school students, including instructions, exercises, and feedback on transactive communication, materials and tasks on curriculum-related content, and working with various cooperative learning methods. SampleIn a quasi-experimental pre-test post-test design, 594 ninth-grade students in 23 classes received training in transactive communication or presentation skills. A complete set of data exists for a parallelized sample of 82 students in each condition. MethodsAt both points of measurement, students worked in dyads, and their communication was audiotaped, transcribed, and their transactive statements and non-transactive, content-related externalizations were coded. Furthermore, students completed knowledge tests about the topic of partner work and reported on their experiences with collaboration and motivation for group work (trait). ResultsAnalyses revealed positive effects of the training in transactivity on transactive statements and experiences with collaboration. Students with the training in transactive communication also produced more externalizations. However, no differences were found for students’ knowledge acquisition and motivation for group work. ConclusionThe training in transactive communication was effective for the collaborative working process, but transfer effects need to be further investigated.

ЕФЕКТИВНІ СТРАТЕГІЇ ДЛЯ ПОКРАЩЕННЯ НАУКОВОЇ КОМУНІКАЦІЇ АНГЛІЙСЬКОЮ МОВОЮ

The article discusses the main strategies for improving scientific communication in English. It has been determined that the process of obtaining a university education includes educational and research components. The educational component includes the formation of English-language academic competence, the research component requires mastery of a scientific style of speech, since the essence of scientific communication in English is the exchange of information between a group of people united by common ideas and interests. In addition, it has been determined that effective formation of scientific communication in English for students is possible if a systematic approach to learning a foreign language is implemented. Formal (scientific publications and dissertation defenses) and informal communication in a virtual environment (conversations of scientists, speeches at conferences, electronic correspondence, other forms of computer communication) have been considered. Various aspects of scientific communication have been analyzed. It has been found that effective scientific communication requires an understanding of the audience (interacting with different groups, such as scientists, students, the public, politicians and financial partners, requires adapting the communication approach to their unique interests, technical level and perception of information), creating active interaction (creating forums for discussion where scientists and the audience can exchange ideas, questions and answers), using simple and understandable speech (avoiding complex terms and technical vocabulary, using analogies, definitions), using visual aids (interactive presentations, videos, graphics), use of modern technologies (social networks Twitter, Facebook and LinkedIn, websites and multimedia tools). Based on the analysis, the conclusions have been drawn that effective scientific communication is possible if the right strategies and tools are used. We see the study of scientific communication as a component of scientific and pedagogical activity as a perspective for further exploration.
