Navigating in an unknown area safely is counted as the underlying work which can support swarm agents for more complex tasks. When available information of search regions are lacking, agents make real-time action decisions according to surrounding environments they have perceived. For swarm agent system, connectivity maintenance and collision avoidance are both essential. Based on optimal Reciprocal Collision Avoidance (ORCA) algorithm, we proposed a method that agents can provide assistances to surrounding agents by spreading the status information of themselves, which is the neighbor reward method (NRM). This kind of status information contains ambient information and perceptions of the task which are transferred to reward data for convenient and uniform distributions. In other words, individuals utilize inter-neighbor interactions to achieve the same high-level goal, as well as result in an intelligent independent swarm agents system. This method solves the velocity selection problem of ORCA and optimizes the obstacle avoidance of the original NRM. The algorithm has been integrated in ROS framework and simulated on GAZEBO. In the tested scenario, our method is efficient for swarm agents collision avoidance in decentralized way. © Published under licence by IOP Publishing Ltd.

File transmission is a key concern of Intranet Security Monitoring. Compared with explicit file transmission within a single system, the implicit transmission of files across various business systems is a difficult problem in current Intranet Security Monitoring. In order to shield the differences of file operations in various business systems, explore the clues of implicit file transmission across different business systems, and realize the retrospective security analysis of complex scenarios related to file transmission, this paper proposes an effective technical framework. Firstly, it takes network flow as the main data source, aiming at different business applications and focusing on files, and extracts valuable business information from flow data. Secondly, it reorganizes key elements such as files, users, and terminals in business information, and uses the file transmission process as a link to form unified high-value clue data. Thirdly, it integrates multiple clues, designs and builds a unified file transmission graph data based on an open-source graph database. Finally, an example of security analysis on the implicit transmission of suspicious files based on the above is given, the results show that the organized file element graph data proposed in this paper can effectively describe the transmission of the same files across different business systems. © 2022 SPIE.

An essential feature of the intelligent transportation system is the automatic detection and recognition of license plate information. The e-payment systems for parking and toll collection in traffic control security could be utilized with this application. Numerous algorithms have been created for License Plate Recognition (LPR) and Identification, each with pros and cons depending on the circumstances. computer vision has increased in terms of techniques and developments since deep learning emerged and became popular in several artificial intelligence domains. It is one of the most efficient ways to monitor traffic signals, tax paid for parking, and police monitoring through Automatic LPR. Although it, as a technology, is widely used and developed, much more must be done to improve the system's accuracy. The current science community has excelled in efficiency and problem-solving in recent years. Along with the You Only Look Once (YOLO), targeted at the object detection area and applied to this study, our primary goal is to summarize and analyze several methods and advancements in LPR in the deep learning age. © 2024 IEEE.

Chronic melancholy, lack of interest or enjoyment in activities, changes in diet or weight, abnormalities in sleep patterns, feelings of guilt or unworthiness, difficulty in concentration, and suicide or death thoughts are all symptoms of depression. Depression, if left untreated, can lead to a variety of problems, including an increased risk of self-harm or suicide, substance abuse, physical health issues, and social isolation. In this work we attempt to utilize machine learning techniques to detect a likely depressed social media user based on social media posts and compare the accuracy of built-in models using a variety of comparison methodologies. The machine learning algorithms were fine-tuned on five various optimization techniques. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.

This paper proposes an algorithm of divide-compare-swap-based (DCS) sorting that reduces time complexity by utilizing quantum parallelism. A new cost optimized comparator circuit has been designed and simulated using qiskit for comparing two quantum numbers. The sorting process consists of divide, compare-swap and merge. The set of n quantum numbers are divided equally into two sub arrays followed by comparing-swapping of two middle elements. This process continues in two sub arrays till array with single element is found. The sorting circuit performs well in qiskit with time complexity n, which has a significant improvement over existing quantum sorting technique. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.
