The COVID-19 pandemic has already ravaged the world for two years and infected more than 600 million people, having an irreparable impact on the health, economic, and political dimensions of human society. There have been many papers proposing various Internet of Things (IoT) solutions to stop the spread of COVID-19, such as virus tracking, infection control, medical treatment, and health management. Due to the high popularity of IoT devices, many studies have systematically investigated related technologies, evaluating the development, and application of IoT solutions from different aspects, such as electronic security, personal privacy, disaster prediction, and artificial intelligence (AI). However, the usefulness of IoT in combating COVID-19 has not been thoroughly evaluated. Therefore, this article systematically analyzes high-quality articles published in well-known international journals and conferences from 2019 to 2022 and divides them into the technical development of prevention and treatment according to the application field of the solution, cross-comparing the research results. It provides a comprehensive assessment of the maturity of the current IoT solutions through the Standard Technology Readiness Level (TRL). Finally, through the technical efficacy matrix, the application status and development direction of the international IoT technology are analyzed by patent. Our results reveal the maturity and limitations of existing technologies to fight COVID-19. Possible future research directions are also discussed. © 2014 IEEE.

Food Infestation Detection is more important for food safety and health concerns. It is a challenging task to separate the grains into infested or non-infested. It is found that in the existing system, there is no effective approach for the early detection of pest populations and for classifying crops as infested or non-infested. Therefore, the identification and categorization of early-stage grain infestations is in high demand. To address the above problem, this research presents a better technique for detecting and classifying infested and non-infested grains. Initially, the maize, wheat and olive image datasets are collected, which are then pre-processed using data normalization and adaptive wiener filtering (AdwF) approach to improve the excellence of the input images. Image quality helps in achieving better performance and also helps in analyzing the quality of food grains effectively. Feature extraction is done using the Dense Residual Pyramidal Dilated Convolution Network (DR-PDCNet) technique, and feature selection is done using the Linear Discriminant Coati Optimization (LD-CoA) algorithm. The Hybrid Convolutional Bi-LSTM based Deep Maxout Network (HCBiL-DMN) model is used to detect the infected food grains in the preserved food grains with high accuracy. This research explores the potential and future possibilities for using technology to ensure the quality, assessment, and monitoring of nutritional grains during storage. The performance results are achieved with 98.3% accuracy, 99.12% recall, 98.65% precision, 98.02% MCC, and 99.32% F1 score. © The Author(s), under exclusive licence to Springer science+Business Media, LLC, part of Springer Nature 2024.

LS-SIFT: Enhancing the Robustness of SIFT During Pose-Invariant Face Recognition by Learning Facial Landmark Specific Mappings

引用

IEEE Access 2024年 12卷 76648-76662页

The proper functioning of many real-world applications in biometrics and surveillance depends on the robustness of face recognition systems against pose, and illumination variations. In this work, we employ ensemble systems in conjunction with local descriptors to address pose-invariant face recognition (PIFR). Facial landmarks are detected during the first step with a two fold usage. The landmark locations are employed to perform head pose classification (HPC). HPC allows to select only the visible landmarks for further processing. Then, local descriptors are extracted from the selected landmarks within a face image. We are proposing a novel learned descriptor (LS-SIFT) to overcome the robustness limitations of SIFT against large viewpoint variability during face recognition. Second, the extracted descriptors are used to train the base learners comprising an ensemble system for each subject in a face database (one ensemble per subject, one base learner per landmark). A novel GMM-based base learner model, named Mahalanobis Similarity (MS), is introduced in this work. Finally, face recognition is performed based on the ensemble systems' outputs from all the subjects in a face database. During the experimental trials, SIFT and LS-SIFT are employed individually for local feature extraction, whereas GMM and MS are used to build the ensemble systems, in an independent manner, for further comparison. The whole PIFR system is tested on CMU-PIE, Multi-PIE, and FERET databases, outperforming most of the state-of-the-art works regarding images with pose angles in the range of pm 90{o}. © 2013 IEEE.

Minimum spanning tree cycle intersection problem on outerplanar graphs

引用

Discrete Applied Mathematics 2024年 343卷 328-339页

作者： Su, Tai-Yu Department of Computer Science and Information Engineering National Taiwan University Taipei10617 Taiwan

We study the minimum spanning tree cycle intersection (MSTCI) problem on outerplanar graphs in this paper. Consider a connected simple graph G=(V,E) and any spanning tree T=(V,ET) of G, it is well-known that each non-tree edge e∈E∖ET induces a fundamental cycle in T∪{e}. We say that two distinct fundamental cycles intersect if they share at least one edge. The MSTCI problem seeks a spanning tree such that the number of pairwise cycle intersections is minimized. We provide a linear-time algorithm to solve the problem on outerplanar graphs by exploiting the cycle-cut duality on plane graphs. Besides, we show that the minimum cycle intersection number is bounded by O(n) for outerplanar graphs with n vertices. © 2023 Elsevier B.V.

Multi-Tree-Based Avoidance Multicast Routing for Wireless Sensor Networks

IEEE Transactions on Green Communications and Networking

Multi-path avoidance routing for wireless sensor networks (WSNs) is a secure routing paradigm against adversaries with unbounded computational power. The key idea of avoidance routing is to encode a message into several pieces by the XOR coding, and each piece is routed via different paths. Then, an adversary cannot obtain the original message unless she eavesdrops on all message pieces from all the paths. In this paper, we extend such an approach into secure multicast routing, which is a one-to-many communication primitive. To this end, we propose the multi-tree-based avoidance multicast routing protocol (AMRP) for WSNs, in which a set of adversary disjoint trees is discovered, i.e., a set of multicast trees with no common adversaries. When a set of multicast trees is adversary disjoint, no adversary can eavesdrop on all message pieces to recover the original message. In addition, optimized AMRP (OAMRP) is proposed in order to reduce the control overhead of AMRP, where additional multicast trees are used for only a subset of destination nodes with no single safe tree. The simulation results demonstrate that the proposed protocols achieve higher secure delivery rates than a simple extension of the existing unicast avoidance routing protocol. IEEE

Multistage Parameter Optimization for Rule Generation for Multistage Manufacturing Processes

引用

IEEE Transactions on Industrial Informatics 2024年第3期20卷 3857-3867页

作者： Wahyuni, Ida Chang, Chin-Chun Yang, Hua-Sheng Wang, Wei-Jen Liang, Deron National Central University Department of Computer Science and Information Engineering Taoyuan32001 Taiwan National Taiwan Ocean University Department of Computer Science and Engineering Keelung20224 Taiwan

Defects in multistage manufacturing processes (MMPs) decrease profitability and product quality. Therefore, MMP parameter optimization within a range is essential to prevent defects, achieve dynamic accuracy, and accommodate manufacturing tolerances. However, existing studies only focused on optimization in a single manufacturing stage of MMP, such as the weaving stage in fabric manufacturing. Furthermore, existing methods optimize for a single value rather than a range. Thus, we propose a novel approach called multistage parameter optimization for rule generation (MPORG) to prevent the occurrence of defects in MMPs. In the proposed approach, key parameters are identified and optimized to a range for each defect type. Subsequently, the optimized parameters for each defect type are merged. Our approach is novel because it optimizes parameters to a range rather than a single value, allowing engineers to select a value in this range according to their experience. It also provides results that are specific to a product type. Our approach outperformed the classification and regression tree (CART) algorithm and multiresponse CART method in experiments on an empirical fabric manufacturing dataset that we gathered. The experimental results demonstrated that the MPORG approach can prevent the occurrence of single-type or multiple-type defects by approximately 89%. © 2005-2012 IEEE.
