Vehicular ad hoc networks (VANETs) are an essential element and building block of the autonomous vehicle system. VANETs, a subcategory of mobile ad hoc networks (MANETs), stand out due to certain predetermined attributes. In VANETs, optimal path routing offers solutions to address issues like traffic density, node mobility, link failure, and bandwidth. Finding the optimal VANET road path between source and destination conditions is difficult. Extensive paths increase network overhead, communication costs, and failure probability, reducing routing efficiency. We present the new traffic density-based stigmergic ant colony optimization routing (CSG_IACO) to improve routing performance. Improved ant colonies stimulate the proposed CSG_IACO, which measures inter-vehicular density. Ant behavior serves as the inspiration for the improved ACO technique, a meta-heuristic methodology. Phase 1 of the CSG_IACO involves using the traffic density to form a cluster among the vehicles. Phase 2 of the suggested approach is Stigmergy-based ant colony optimization, which guides ants to indirectly communicate with each other to act upon the change in the environment to find a best path. This improves protocol efficiency in all aspects. The simulations using NS 2.35 and SUMO indicate that the proposed system considerably reduces obstacles to finding the optimal path compared to existing systems. The simulations show that our suggested scheme performs better than AODV-DATRLD, ACO-DATRLD, and CaCOIoV in terms of performance including the count of delivered packets, throughput, end-to-end delay, the average count of cluster formations per cluster head, and the number of dropped packets. © Bharati Vidyapeeth's Institute of Computer Applications and Management 2025.

引用

Acta Mathematicae Applicatae Sinica 2025年第2期41卷 400-413页

This paper deals with numerical solutions for nonlinear first-order boundary value problems(BVPs) with time-variable delay. For solving this kind of delay BVPs, by combining Runge-Kutta methods with Lagrange interpolation, a class of adapted Runge-Kutta(ARK) methods are developed. Under the suitable conditions, it is proved that ARK methods are convergent of order min{p, μ+ν +1}, where p is the consistency order of ARK methods and μ, ν are two given parameters in Lagrange interpolation. Moreover, a global stability criterion is derived for ARK methods. With some numerical experiments, the computational accuracy and global stability of ARK methods are further testified.

The increasing complexity of cryptocurrency markets necessitates the development of efficient portfolio management tools that provide real-time tracking, price updates, and market awareness. This paper focuses on an advanced concept of a cryptocurrency wallet service provision that provides a summary of available coins, their prices, available quantities, and customers' transaction histories. Developed for the 'frontend' using *** and for the 'backend' using ***, which uses the CoinGecko API for receiving live market prices and collecting curated news blog articles from other APIs. The data related to the wallets are efficiently managed since the application is built based on the MongoDB schema, and in addition to this, the user authentication is also integrated. A responsive design of the user interface allows for showing both a portfolio summary and the latest news related to cryptocurrencies, thus suggesting an 'everything in one place' solution for users interested in cryptocurrencies. This system shows how real-time data integration could be implemented, how the system is friendly to users, and how the system manages the content. This system could be expanded in the future with predictive analytics and an AI recommendation system for the portfolio management and contents. © 2025 IEEE.

IMGWOFS: A Feature Selector with Trade-off between Conflict Objectives for EEG-based Emotion Recognition

引用

IEEE Transactions on Affective computing 2024年第02期16卷 1-13页

作者： Luo, Gang Sun, Shuting Yan, Chang Qu, Shanshan Wang, Dixin Chu, Na Liu, Xuesong Tian, Fuze Qian, Kun Li, Xiaowei Hu, Bin Beijing China Gansu Provincial Key Laboratory of Wearable Computing School of Information Science and Engineering Lanzhou University Lanzhou China

Feature selection is a crucial step in EEG emotion recognition. However, it was often used as a single objective problem to either reduce the number of features or maximize classification accuracy, while neglecting their balance. To address the issue, we proposed Improved Multi-objective Grey Wolf Optimization Feature Selection (IMGWOFS). Firstly, we designed a population initialization operator via discriminability and independence of features to accelerate search speed. Secondly, we employed a two-stage update strategy to improve the global search capabilities of the EEG feature subsets. Finally, we incorporated an adaptive mutation operator to escape the local optima. We conducted experiments on SEED and DEAP datasets, and the accuracy were 86.87$\pm$1.62 % and 60.65$\pm$1.51 % in the beta band using a smaller number of EEG features. In addition, the frontal lobe was related to emotion processing. In conclusion, IMGWOFS is an effective and feasible feature selection method for EEG-based emotion recognition. IEEE

Virtual consultation systems in healthcare also known as telemedicine a two-way technologically driven platforms or tools that enable healthcare providers to connect with patients virtually or remotely to deliver medical services, diagnoses, consultations, or treatments. This research examines the impact of virtual consultation systems (telemedicine) on patients in Kano state, Nigeria, and identifies associated challenges, limitations, and ethical and legal considerations. Using a survey descriptive research design, 211 patients from six hospitals were selected through purposeful and stratified random sampling. Data were collected via the Patient Satisfaction Survey Questionnaire (PSSQ), validated by experts, and tested for reliability. Analysis indicated several recommendations: prioritization of virtual consultation by the government, emphasis on AI by healthcare professionals, provision of online medical data, adoption of 5G technology, use of virtual consultations for chronic condition monitoring, and increased sensitization efforts by hospital management. A descriptive survey research design was utilized in the study, which involved 211 patients from six primary and general hospitals located around the state of Kano. The purpose of the study was to evaluate the effects that Kano patients received from virtual consultation systems, as well as the difficulties and restrictions associated with virtual conferences and the related ethical and legal issues. © 2024 IEEE.
