Remote sensing images are the product of information obtained by various sensors, and the higher the resolution of the image, the more information it contains. Therefore, improving the resolution of the remote sensing image is conducive to identify Earth resources from the remote sensing image. In this article, we present a multiple-branch panchromatic image resolution restoration network based on the convolutional neural network to improve the spatial and spectral resolution of the panchromatic image simultaneously, named MBPRR-Net. Specifically, we adopt a multibranch structure to extract abundant features and utilize a feature channel mixing block to enhance the interaction of adjacent channels between features. Feature aggregation in our method is used to learn more effective features from each branch, and then a cubic filter is utilized to enhance the aggregated features. After feature extraction, we use a recovery architecture to generate the final image. Moreover, we utilize image super-resolution to restore spatial resolution and image colorization to restore the spectral resolution so that we can compare it with some image colorization and super-resolution methods to verify the proposed method. Experiments show that the performance of our method is outstanding in terms of visual effects and objective evaluation metrics compared with some existing excellent image super-resolution and colorization methods. © 2008-2012 IEEE.

software testing is a critical phase in software development to ensure the reliability and quality of software systems. With the increasing complexity of software applications, the number of test cases can grow significantly, posing challenges in terms of execution time and resource utilization. Test Case Prioritization (TCP) has emerged as a crucial technique to optimize the order of test case execution, aiming to detect defects early in the testing process. This paper presents a novel approach to Test Case Prioritization by harnessing the power of Rat Swarm Optimization (RSO), an algorithm inspired by the collective behavior of rat colonies. Experimental results demonstrate the efficacy of our approach compared to another algorithm. This study evaluates the performance of the proposed method using the execution time taken and compared it with the others algorithm like Ant Colony Optimization (ACO), Artificial Bee Colony (ABC) algorithm, and Firefly algorithm. The results indicate that the Rat Swarm Optimizer (RSO) algorithm is notably more efficient in terms of execution time compared to the other tested algorithms. The results highlight the potential of RSO for applications requiring rapid test case prioritization, where minimizing execution time is critical. This paper underscores the potential of RSO as a viable and innovative solution for Test Case Prioritization, offering software developers and testers a valuable tool for enhancing the efficiency and effectiveness of software testing processes. © 2024 IEEE.

Addressing the need for improved GPS accuracy, especially for low-dynamic users, this study introduces a GPS augmentation system employing Low Earth Orbit (LEO) satellites. We detail the principles of satellite navigation and augmentation and simulate the GPS-LEO constellation to analyse its performance in terms of satellite visibility and Position Dilution of Precision (PDOP). The results demonstrate substantial augmentation in navigation accuracy with the integrated system, as verified by UAV flight experiments. The integration of LEO satellites is anticipated to advance global navigation capabilities, with implications for intelligent transportation, logistics, and precision agriculture. © 2025 Institute of Physics Publishing.

Towards Understanding Machine Learning Testing in Practise

Visualisations drive all aspects of the Machine Learning (ML) Development Cycle but remain a vastly untapped resource by the research community. ML testing is a highly interactive and cognitive process which demands a human-in-the-loop approach. Besides writing tests for the code base, bulk of the evaluation requires application of domain expertise to generate and interpret visualisations. To gain a deeper insight into the process of testing ML systems, we propose to study visualisations of ML pipelines by mining Jupyter notebooks. We propose a two prong approach in conducting the analysis. First, gather general insights and trends using a qualitative study of a smaller sample of notebooks. And then use the knowledge gained from the qualitative study to design an empirical study using a larger sample of notebooks. Computational notebooks provide a rich source of information in three formats-text, code and images. We hope to utilise existing work in image analysis and Natural Language Processing for text and code, to analyse the information present in notebooks. We hope to gain a new perspective into program comprehension and debugging in the context of ML testing. © 2023, CC BY.

In the era of digital transformation, the sheer volume of network security data poses significant challenges in terms of organization and retrieval. Traditional search engines fail to provide contextual answers, necessitating the development of more advanced systems. This paper presents the design and implementation of a network security knowledge base enhanced with a knowledge graph. The proposed system aims to improve the efficiency of information management and retrieval for network security professionals. We discuss the multi-layer architecture of the knowledge base, which includes the UI, service, data access, and data storage layers. The knowledge graph is constructed through a four-layer architecture comprising the data, extraction, knowledge, and application layers. Using the Scrapy framework, we efficiently crawl and extract data from various online sources. This data is processed with the Jena tool and stored in Neo4j as structured triples, enabling complex queries and advanced analytic. Our system supports semantic queries, knowledge association discovery, and intelligent question answering, improving user experience and decision-making in network security management. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.

With the development of science and technology, modern war has changed from traditional mechanized war to electronic war. Electronic warfare has become the mainstream combat mode in modern war. At present, the electromagnetic environment is very chaotic and complex, the pulse density increases rapidly, and the pulse modulation mode is complex and changeable. In order to deal with the low efficiency of traditional methods in complex electromagnetic environment, a distributed feature reduction signal sorting method is proposed. Firstly, attribute entropy regularization is added to the objective function, and different weights are given to different features. Secondly, the feature reduction process is added to select which dimension of features to be discarded by setting the threshold. Each iteration of the algorithm will update the membership matrix, cluster center and feature weight matrix until the termination conditions is satisfied. Simulation results show that the algorithm can reduce the number of iterations and time, and improve the accuracy of radar signal sorting results by reducing the number of features. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

作者： Leonhard Applis Annibale Panichella Software Engineering Research Group (SERG) Delft University of Technology Delft Netherlands

We present HasBugs, an extensible and manually-curated dataset of real-world 25 Haskell Bugs from 6 open source repositories. We provide a faulty, tested, and fixed version of each bug in our dataset with reproduction packages, description, and bug context. For technical users, the dataset is meant to either help researchers adapt techniques from other programming languages to Haskell or to provide a human-verified gold standard for tools evaluation and enable future reproducibility. We also see applicability for qualitative research, e.g., by analysis of bug lifecycles and comparison to other languages. We provide a companion website for easy access and overview under https://***/HasBugs/.
