In this paper, a study of the recent advancements in occluded face recognition is made. Recently, this has become very relevant due to the outburst of corona virus. Because of the seriousness of the spread of the disease, every person wore a mask, and it became challenging for automated systems to identify the person. So, it became the need of the hour to find new techniques for occluded face detection. In the years 2021 to 2022, many papers have been published in this regard. Researchers all over the world have contributed significantly towards occluded face recognition. Also, the advancement of deep learning has helped researchers a lot in implementing innovative techniques to deal with the challenges in face recognition, especially occluded faces, which is considered one of the most difficult challenges to overcome. This paper intends to push the limits further and encourage researchers to find more innovative techniques for occlusion-independent face recognition. In this paper, the recent publications in this field are studied. This paper gives an insight into different algorithms which use Convolutional Neural networks, Deep Learning, Attention mechanism, Dictionary representation, Simultaneous segmentation, Joint segmentation and identification, etc., for occluded face detection and recognition. Incorporating these strategies in face recognition has substantially improved the recognition rate, specifically for occluded face recognition. Additionally, the databases for training occluded face recognition algorithms lack adequate data. This paper also gives an insight into the recent databases available for training occluded face recognition algorithms. Also, different methods for obtaining synthesised occluded faces are discussed. © 2024 IEEE.

In this article, an intelligent fault detection mechanism is proposed to classify multiple electrical faults. Various electrical faults like line-line fault, open circuit fault, short circuit faults, and line-to-ground faults are studied in detail. Voltage and current sensors placed at each solar photovoltaic (SPV) array string collect the data during these fault conditions. Machine learning and Deep learning techniques are used to classify the type of fault and can even detect the exact location of the fault. A mismatch detection circuit consisting of a boost converter and optocoupler is designed to differentiate between mismatch faults and electrical faults;this circuit design also indicates the exact location of a mismatch fault. The proposed method is implemented in the Python platform and the results are analysed. © 2025 IEEE.

Plenty of Bayesian-consistent, heuristic and statistical classifiers have been introduced. Although support vector machines, deep neural networks, and random forests exhibit acceptable performance in several fields, their primary challenge lies in the lengthy training phase, especially when dealing with big data. K-nearest neighbors (KNN) is one of the simplest, Bayesian consistent and most common algorithms for classification tasks which locally makes its decision and there is no need to any training phase, can be implemented by parallel processing algorithms which makes it suitable to deal with big datasets. The core of this classifier relies on measuring the distance between test samples and its neighbors. Therefore, designing a hybrid distance technique to better find relevant neighbors is of interest. In this research, a weighted combination five distances has been proposed to optimize the performance of the KNN algorithm on diverse 28 datasets. To select appropriate weights of distances for each dataset, particle swarm optimization algorithm was used due to its simplicity and high convergence speed. The proposed method was applied to the datasets, demonstrating acceptable performance compared to its rivals. © 2023 IEEE.

IEEE/CAA Journal of Automatica Sinica 2023年第10期10卷 2014-2025页

High-speed rail(HSR) has formed a networked operational scale in China. Any internal or external disturbance may deviate trains’ operation from the planned schedules, resulting in primary delays or even cascading delays on a network scale. Studying the delay propagation mechanism could help to improve the timetable resilience in the planning stage and realize cooperative rescheduling for dispatchers. To quickly and effectively predict the spatial-temporal range of cascading delays, this paper proposes a max-plus algebra based delay propagation model considering trains’ operation strategy and the systems’ constraints. A double-layer network based breadth-first search algorithm based on the constraint network and the timetable network is further proposed to solve the delay propagation process for different kinds of emergencies. The proposed model could deal with the delay propagation problem when emergencies occur in sections or stations and is suitable for static emergencies and dynamic emergencies. Case studies show that the proposed algorithm can significantly improve the computational efficiency of the large-scale HSR network. Moreover, the real operational data of China HSR is adopted to verify the proposed model, and the results show that the cascading delays can be timely and accurately inferred, and the delay propagation characteristics under three kinds of emergencies are unfolded.

In recent years, the rapid development of UAV technology has opened up a wide range of application prospects, but unauthorized UAV flights pose potential threats to low-altitude airspace security. Existing monitoring methods often rely on expensive high-precision equipment or single-sensor systems, making it difficult to achieve low-cost yet high-accuracy UAV localization and identification. A localization method based on a multi-sensor fusion strategy combining RF and visual data, that is, integrating RF TDOA localization technology with lightweight YOLO visual localization technology (TAYT, TDOA, and YOLO technology) is proposed in this paper. The method isolates the radio frequency bands used by the UAV, discovers the UAV through RF TDOA frequency scanning positioning, and combines Yolo images to locate the UAV. Experimental results demonstrate that this approach overcomes issues such as large errors caused by the susceptibility of spectrum sensors to environmental noise interference and non-line-of-sight effects. The minimum error of the positioning error is about 2.79 meters compared to the reference standard. A low-cost and high-efficiency positioning technology for effective low-altitude UAV monitoring is provided in this paper. © 2025 Institute of Physics Publishing. All rights reserved.

The world is filled with exciting technologies and ideas;scientists build machines to avoid human intervention in completing work. It is highly challenging to complete the task without the Artificial Intelligence (AI) Technology intervention. With the technological development, certain processes or consultations are performed with the aid of doctors available around the world. In this scenario, it could be noticed that health care is one of the world's expected domains that require the most incredible attention in data security while performing data transfer. Nodes in the network are considered based on the weakest link to overcome the cyber attacker's issues. Besides building the software for data storage, a better mechanism has to be incorporated to provide security to the stored data. This process is a delicate task for every network engineer. This paper will explain such concepts related to health prediction and health care by building the most robust network security systems. Finally, the discussion would cross over human-looping systems, which act as one of the common problems that are affected mentally for a person. The proposed optimized neural network model is compared with the existing data summarization method. From the results it is observed that the proposed model achieves an accuracy of 98.89% which is 4.76% higher than the existing model. © 2022 IEEE.

Leptospirosis is one of the zoonotic infectious diseases that was usual in tropical countries. The Leptospira bacteria that causes the infection comes from the urine of infected rodents and other animals and they can affect both humans and other animals by urinating on water and contaminate it. The symptoms of infection are confusing. Confusion and wrong medication can result to slow handling of the case. A software-based detection system was developed for the detection of Leptospira through image processing using 2D cross-correlation and normalized 2D cross-correlation. Bacteria features were used to compare and match to the captured images. For validation, sample images captured from a mobile phone were sent to the laboratory testing center. Result of bacteria count, confirmation of detection and data set collections were achieved by the study and translated in the Graphical User Interface (GUI) created. An accuracy of 100% was achieved during validation. © 2022 IEEE.

Cell-Free ISAC MIMO Systems: Joint Sensing and Communication Beamforming

引用

IEEE Transactions on Communications 2024年

作者： Demirhan, Umut Alkhateeb, Ahmed Arizona State University School Of Electrical Computer And Energy Engineering United States

This paper considers a cell-free integrated sensing and communication (ISAC) MIMO system, where distributed MIMO access points (APs) jointly serve the communication users and sense the target. For this setup, we derive a sensing SNR for multi-static sensing where both joint communication and sensing signals transmitted by different APs are utilized. With this sensing objective, we develop two baseline approaches that separately design the sensing and communication beamforming vectors, namely communication-prioritized sensing beamforming and sensing-prioritized communication beamforming. Then, we consider the joint sensing and communication (JSC) beamforming design and derive the optimal structure of these beamforming vectors based on a max-min fairness formulation. In addition, considering any pre-determined JSC beam design, we devise a power allocation approach. The results show that the developed JSC beamforming is capable of achieving nearly the same communication signal-to-interference-plus-noise ratio (SINR) of the communication-prioritized sensing beamforming solution with almost the same sensing SNR of the sensing-prioritized communication beamforming approach. The proposed JSC beamforming optimization also provides a noticeable gain over the power allocation with regularized zero-forcing beamforming, yielding a promising strategy for cell-free ISAC MIMO systems. © 1972-2012 IEEE.
