A three‐dimensional parabolic equation with fast reordered‐alternate direction decomposition in atmosphere duct environment

AbstractIn the design and optimisation of marine wireless communication and navigation systems, a thorough investigation of radio wave propagation characteristics under atmospheric ducting conditions is essential. The authors aim to enhance the efficiency of radio wave propagation loss prediction in marine atmospheric ducting environments, proposing a prediction model based on Fast Reordered‐Alternate Direction Decomposition (FR‐ADD). By approximating the diffraction term into three independent components, exploiting the commutative properties of the Fourier transform to reduce the spatial dimensions, and incorporating a rapid algorithm for the parabolic equation, the model optimises the stepping process and significantly improves computational efficiency. Simulation experiments demonstrate that, in the long‐distance and complex marine ducting environments, the model not only maintains prediction accuracy but also substantially reduces computational load and prediction time, effectively realising over‐the‐horizon propagation prediction. In the experiment of radio wave propagation characteristics in the Yellow and Bohai Seas, the simulation data from the FR‐ADD model showed significant correlation with actual measurements and simulations from the AREPS software, confirming the method's efficiency and practicality.

Research on a Real-Time Control System for Discrete Factories Based on Digital Twin Technology

Gear factories are most typical discrete manufacturing factories. Many gear factories are striving to explore how to achieve intelligent manufacturing in order to improve efficiency and reduce costs. Digital twin technology is currently one of the most reliable ways to achieve intelligent manufacturing. This article aims to establish a real-time control system in order to promote intelligent manufacturing for discrete manufacturing factories. Firstly, a model for a digital twin gear factory is put forward based on the characteristics of gear factories, and the composition of a real-time control system for gear factories is clarified. Then, a human–computer interaction architecture for the real-time control system is proposed. The real-time control system consists of three parts as follows: a monitoring module, a virtualizing module, and a controlling module. At work, it appears as a kind of human–machine interaction form with the three following interfaces: a monitoring window, a virtualizing window, and a controlling window. Finally, a gear factory, which is specialized in manufacturing the intermediate shaft dual gear of a new energy vehicle gearbox, develops a set of software for the real-time control system. The prototype software is obtained through some development activities such as 3D MAX and WebGL virtualization modeling and OPC UA and REST communication design.

Teaching child-computer interaction: Critical reflections on a project-based interaction design course

As a response to a recent call for developing teaching materials and sharing examples of good teaching practice in Child-Computer Interaction (CCI), this paper describes previous experiences from incorporating an existing CCI curriculum into an Interaction Design course, that is mandatory for third year Bachelor students enrolled in Communication Design program. This article is an attempt to reflect on the four-year experience constructively and critically in teaching and progressively developing an existing CCI course. The paper describes key elements to teaching how to carry out a theory-oriented and project-based design course formulated around the challenge of interaction design with and for children. As the paper reflects on previous experiences, the contribution of this paper is including formal procedural research ethics into student project proposals as part of core principles and giving students the possibility to manage a group work on several iterations for the same project throughout the semester. I discuss some of the reflections on the teaching experience for interaction design and children have posed to me as a CCI researcher and university teacher and outline a set of lessons learned that I think would shed a light for taking ethical approval for student project works in future CCI teaching practices.

Joint In-Orbit Computation and Communication for Minimizing Download Time From LEO Satellites

Downloading a large amount of data from a low Earth orbit satellite to a ground station can be challenging due to the limited contact window, dynamic channel quality, solar energy supply, and thermal management without an atmosphere. Considering such dynamics, this paper proposes a joint design of in-orbit computation and communication for download time minimization. We combine the non-convex thermal constraints and energy constraints into unified energy budget constraints with upper bound approximation, and computational efficiency is achieved by decomposing the resulting large-scale problem into a non-convex communication sub-problem, a convex computation sub-problem solvable with interior point method and a master problem that optimizes the energy budget allocation between computation and communication. The communication sub-problem is solved with a generalized-benders-decomposition-based algorithm that decouples downlink scheduling and power allocation based on a closed-form solution of optimal dual variables in the power allocation primal problem. And the master problem is solved with ternary search by proving the minimal download time is quasi-convex with respect to the energy budget allocation between computation and communication. Simulation results demonstrate that the proposed solution effectively reduces the download time, especially under strict energy constraints and severe channel variations.

A Joint Communication and Computation Design for Probabilistic Semantic Communications.

In this paper, the problem of joint transmission and computation resource allocation for a multi-user probabilistic semantic communication (PSC) network is investigated. In the considered model, users employ semantic information extraction techniques to compress their large-sized data before transmitting them to a multi-antenna base station (BS). Our model represents large-sized data through substantial knowledge graphs, utilizing shared probability graphs between the users and the BS for efficient semantic compression. The resource allocation problem is formulated as an optimization problem with the objective of maximizing the sum of the equivalent rate of all users, considering the total power budget and semantic resource limit constraints. The computation load considered in the PSC network is formulated as a non-smooth piecewise function with respect to the semantic compression ratio. To tackle this non-convex non-smooth optimization challenge, a three-stage algorithm is proposed, where the solutions for the received beamforming matrix of the BS, the transmit power of each user, and the semantic compression ratio of each user are obtained stage by stage. The numerical results validate the effectiveness of our proposed scheme.

The application of graphic language personalized emotion in graphic design

Emotion Recognition is the experience of attitude in graphic language expression and composition. People use both verbal and non-verbal behaviours to communicate their emotions. Visual communication and graphic design are always evolving to meet the demands of an increasingly affluent and culturally conscious populace. When graphic designing works, designers should consider their own opinions about related works from the audience's or customer's standpoint so that the emotion between them can resonate. Hence, this study proposes a personalized emotion recognition framework based on convolutional neural networks (PERF-CNN) to create visual content for graphic design. Graphic designers prioritize the logic of showing objects in interactive designs and use visual hierarchy and page layout approaches to respond to users' demands via typography and imagery. This ensures that the user experience is maximized. This research identifies three tiers of emotional thinking: expressive signal, emotional experience, and emotional infiltration, all of which affect graphic design. This article explores the subject of graphic design language and its ways of emotional recognition, as well as the relationship between graphic images, shapes, and feelings. CNN initially extracted expressive features from the user's face images and the poster's visual information. The clustering process categorizes the poster or advertisement images into positive, negative, and neutral classes. Research and applications of graphic design language benefit from the proposed method's experimental results, demonstrating that it outperforms conventional classification approaches in the dataset. In comparison to other popular models, the experimental results demonstrate that the proposed PERF-CNN model improves each of the following: classification accuracy (97.4 %), interaction ratio (95.6 %), emotion recognition ratio (98.9 %), rate of influence of pattern and colour features (94.4 %), and prediction error rate (6.5 %).

Family Emotional Decorative Paintings: Interaction Design for Communication

This paper describes an approach applied to decorative home paintings: an emotional interaction approach. The study utilizes the theory of constructed emotion and the Wizard of Oz research methodology to extend the user's emotional experience in home scenarios with emotional self-reflection and regulation. Family Emotion Decorative Painting uses the family-shared photo library as the image base data, obtains the emotion type through facial expression and voice emotion recognition, and correlates the moment's emotion with the emotion reacted in the picture. Through qualitative research, we found that family emotional decorative painting can bring emotional arousal and soothing to participants. Family Emotional Decorative Paintings also provoked reflection on technology in and around the home. These findings suggest several opportunities, such as designing for anticipation, better supporting reflection on the past. The study also allowed the team to question the traditional interaction design view that more frequent and prolonged human-computer interactions are a measure of good design. The team will next focus on ways for users to engage in novel and meaningful ways outside of the application.
