The management of computing resources through the computing power network (CPN) has gradually become a focal point of research. With the development of the 6th generation (6G) mobile networks, some promising technologies such as satellite-terrestrial integrated network (STIN) and smart endogenous network driven by artificial intelligence (AI) are increasingly being applied in Industrial Internet of Things (IIoT). However, several issues in current studies are worthy of attention: 1) the large number of devices powered by battery in IIoT, 2) the complex communication environments, 3) the finite computing resources for task data processing. To cope with these challenges, a satellite-terrestrial integrated computing power network (STICPN) framework is introduced in this article. Within this framework, a task offloading link selection scheme is proposed, which minimizes the delay and the consumption of energy. The task offloading optimization problem is modeled as a Markov Decision Process (MDP). Meanwhile, deep reinforcement learning (DRL) algorithm is employed to adapt to the dynamic states of environment. Specifically, a Dueling Double Deep Q Network (D3QN) is used to make optimal decisions and delay as well as energy consumption can be reduced significantly. Moreover, the D3QN-based scheme extends the usage time of IIoT devices. The simulation results indicate that the proposed scheme outperforms the comparison schemes significantly. © 2025 IEEE.

SN computer Science 2025年第1期6卷 1-18页

In automated software testing;optimization of test suites is an important and challenging problem. In the literature of test suite optimization, various single-objective and multi-objective optimization approaches have been proposed by researchers and practitioners. Even though the multi-objective optimization approaches have demonstrated effective performance in test case optimization, their performance tends to degrade when the number of objectives exceeds by more than or equal to three. To tackle this issue, recently few approaches have been proposed. Even though these approaches perform well, there is still scope for improvement. In this work, we introduce a Many-objective Differential Evolution Feedback Evolutionary Algorithm (MDEFEA) for the test case optimization problem. In this approach, we exploit the Differential Evolution (DE) algorithm and information Feedback Model (IFM) concept to optimize line coverage (LC), branch coverage (BC), mutation coverage (MC), and multi-criteria coverage (MCC) simultaneously. To assess the performance of the proposed MDEFEA, we evaluated it across 41 complex projects and compared its results with other similar optimization techniques, including NSGA-III, MOPSO, LSMaOA, and MOEA. The findings of the proposed and existing approaches indicate that MDEFEA outperforms the existing approaches in terms of the Mean Coverage Value (MCV) and Worst Coverage Value (WCV) success rates. Overall, the results demonstrate that the proposed MDEFEA is an effective method for test case optimization containing more than three criteria. © The Author(s), under exclusive licence to Springer Nature Singapore Pte Ltd. 2024.

Blockchain technology has the potential to revolutionize the education sector by improving the legitimacy and security of academic procedures. The academic learning record management records the learner’s academic qualifications and achievements. Keeping track of higher education academic learning records is essential to assess students’ credentials and advance their careers. The COVID-19 outbreak highlighted the need for flexible and collaborative learning systems. However, the processes of recording credit accumulation, verification, and transfer are complicated by the disparate credit schemes found in different universities. This creates the need for an academic credit management system. Secure learning record management is necessary because validating the professional and academic accomplishments listed on the resumé currently poses a challenge. Blockchain can remedy this scenario by guaranteeing data privacy, reducing the possibility of hacking, and offering transparent, traceable academic credentials as well as verification of other achievements. Despite these benefits, challenges are still associated with implementing blockchain in academic learning record management. These include handling multiple credentials with a unique identity, absence of smart contracts, on-chain and centralized storage, scalability problems, transaction costs, restricted control over student data, and inadequate student data recording standards. The main objective of this review is to examine recent studies on blockchain-driven academic learning record management by categorizing them into learning record management and academic credit management. This paper identifies research gaps and suggests further studies and practical applications to enhance transparency, efficiency, and trust in the education system. © The Author(s), under exclusive licence to Springer Nature Singapore Pte Ltd. 2025.

This paper investigated the predictive capabilities of three decision tree models for IoT botnet attack prediction using packet information while minimizing the number of predictors. The study employed three decision tree models (C5, CHAID, and Random Forest) and two additional models (Logistic Regression and Bayesian Network) for comparison purposes. The IoT botnet attack dataset comprised various devices, mainly two types of attacks (Gafgyt and Mirai) and 23 feature engineering variables. Simulation results from all models showed that Accuracy, Precision, Recall, and False Omission Rate (FOR) values are approximately one, with an F1 score of around 0.5. CHAID and C5 models outperform other models in predicting IoT botnet attacks, as they are developed using only four and two variables, respectively. These results demonstrated that decision tree models with fewer variables can perform better than models that utilize all predictors. © 2024 IEEE.

In response to the escalating demand for electricity, the aging process and inherent failures in power lines have become unavoidable challenges in their operational integrity. This research addresses the imperative need for a robust method to detect damage in power insulator disc images, introducing a novel feature extraction technique grounded in color intensity profile transformation and ensemble learning. For the purposes of the research, a specific dataset was developed based on publicly available images of power insulators. The collection consists of 9232 images of insulator discs which included 2184 images of damaged discs. The discernible damages include breakages and burnouts. Two distinct analysis variants were employed. In the first variant (V1), two classification groups were selected: disc with damages and disc without damages. In the second variant (V2), three classification groups were selected: discs without damage, broken discs, and burnout discs. The described research was divided into two successive stages. In the first of them (S1), the transformed color intensity profiles for the prepared data set were built and various machine learning models for their classification were trained and evaluated. In the next stage (S2), previously developed, highest efficient machine learning models, were used to make the detection of various damaged types of overhead line insulator discs. For the first stage of research high-performance results and a high value of the F1 score parameters were obtained (F1 score = 0.999 for the first variant (S1V1) and F1 score = 0.992 for the second variant (S1V2). In the second stage of research and the first variant (S2V1), the highest result of the F1 score was 0.932 and for the second variant (S2V2) F1 score was 0.930. © The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2024.

Sign language recognition is a critical technology for enhancing communication accessibility for individuals with hearing impairments. In this paper, we present a robust and efficient system for sign language recognition using Long Short-Term Memory networks and Mediapipe, a versatile framework for machine learning solutions. Our approach leverages Mediapipe's pre-trained hand detection and tracking models to extract key hand landmarks from video sequences in real-time. These landmarks are then fed into an LSTM network, which is adept at capturing temporal dependencies, to classify various sign language gestures. There are learning aids available for those who are deaf or have trouble speaking or hearing, but they are rarely used. Real-time image processing would be used in the proposed system to handle live sign movements. After that, classifiers would be used to discriminate between different signs, and text would appear in the translated output. The existing systems can detect movements with a significant lag because they only use image processing. Our goal in our work is to develop a cognitive system that is trustworthy and sensitive enough for people with speech and hearing problems to use it in daily activities. © 2024 Copyright held by the owner/author(s).
