As a key component of the Photonic network on chip (PNoC). The electro-optic modulator converts the electrical signal of the processor into optical signal, which is transmitted in the PNoC. The performance of the PNoC is directly affected by the property of the electro-optic converter. A novel electro-optic (EO) modulator adopt dual ITO layers directional coupler is proposed in this paper. Utilizing double layer ITO activation materials Designed a photonic electro-absorption (EA) ITO modulator, it has a double-waveguide structure on both sides, and electro-optic modulation is realized by the EA effect of the ITO surface plasma in the middle island. Due to the double waveguide structure, this EO modulator is extremely suitable for on-chip optical network processor of exceptional architecture, for example, the PRNoC (Photonic Ring Network-on-Chip). We simulated the component adopting FDTD (finite time domain difference method) software. Simulation results and analysis show that the coupling ratio at the input of the modulator is up to 52%, and the extinction ratio (ER) of the EO modulator is −14.2 dB, and the insertion loss (IL) is less than 1.0 dB. The modulator is compact footprint only 9 μm × 1.4 μm, the bandwidth up to 0.4963T bit/S, and the power consumption per bit is 4.354 fJ/bit. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

With many online recruitment portals requesting job applicants to upload their resumes, the automated process of screening and shortlisting candidates can accelerate selection and decision-making. This study explores the use of text similarity measures as an alternative to experienced human hiring managers in processing resumes. Three text similarity measures: Cosine, Sqrt-Cosine, and Improved Sqrt-Cosine (ISC) similarity were utilized as computer programs in scanning resumes for the recruitment of a business development manager and a software engineer. The decisions of the algorithms were compared to those of an expert hiring manager within the same scenarios. The findings indicate that ISC and Sqrt-Cosine were closer to the expert-human decision than Cosine similarity. These specific text-similarity algorithms can also make acceptable decisions even when recruiting for high-level positions and can do so in seconds when executed as a program on a normal CPU processor. This study suggests that these algorithms can efficiently facilitate the process of decision-making in recruitment and shortlisting candidates and can be an effective alternative to expert hiring managers. © 2023 Bharati Vidyapeeth, New Delhi.

Micro-expressions (MEs) refer to spontaneous, subtle, and fleeting facial movements that usually only occur in local facial areas, which can effectively reveal genuine emotions that humans try to hide. However, micro-expression recognition (MER) is still a difficult task due to its low intensity and local movements, and existing datasets are usually small-scale with class imbalance problem. To address these problems, we propose a novel MER framework named Global and Local Mixer (GL-Mixer) based on MLP-Mixer, which can focus on local regions where MEs appear and reduce the influence of ME-irrelevant regions. Specifically, the GL-Mixer mainly consists of three parts: Global Feature Learning (GFL) module, Local Feature Learning (LFL) module, and Feature Refinement (FR) module. The GFL module is designed to learn the global ME features from the whole face region. Meanwhile, the LFL module is composed of multiple parallel local mixers, and each local mixer extracts fine-grained features in a specific facial region. Then, Feature Refinement (FR) module aims to refine the fin e-grained ME features by focusing more on the local features of the effective ME regions and suppressing the features of the irrelevant region under the guidance of the global feature. Last, the model fuses the global and fine-grained ME features for classification. In addition, to solve the problem of insufficient data and class imbalance in ME datasets, we introduce class-balanced implicit semantic data augmentation. Extensive experiments are conducted on CASMEII, SAMM, and SMIC datasets, and the experimental results demonstrate the effectiveness of our method. © 2023 IEEE.

The metaverse is a universal and immersive virtual world, which are components of cyber-physical-social systems (CPSS). The traditional centralized approach to building a metaverse poses risks to user privacy, security, and autonomy. A growing movement towards a decentralized metaverse, built on blockchain and distributed networks, has emerged as a response. This paper presents a conceptual framework for building a de-centralized metaverse emphasising security, user autonomy, and inclusivity within situation-aware CPSS. Drawing on literature from blockchain, virtual worlds, and decentralized systems, we explore the technical and regulatory challenges that must be addressed to create a more secure, autonomous, and inclusive virtual world. Our framework highlights the importance of community-driven governance and transparent data management for building a decentralized metaverse that empowers users and promotes collaboration. © 2023 IEEE.

We often open our eyes in the morning with the appalling news of data breaches of different popular companies. This is a significant threat not only to giant companies but also to the general people's privacy. Various methods are maneuvered for data breaches, and identifying these methods in a short can help understand the loss and take proper steps against these incidents. Researchers nowadays focus on the data breaches issue to reduce its threats to the tech industry. In this research, we have used advanced deep learning methods(e.g., BERT, XLNet, and Electra) to predict data breach methods using the data breach story. The proposed classifier has provided an accuracy of 92.86%. © 2024 IEEE.

This paper proposes an improved semantic segmentation algorithm based on the split attention network resnest. The original icnet semantic segmentation model has some defects in the segmentation of foreground objects. In view of these problems, we optimized the icnet model with resnest network and CBAM convolution attention module. On the one hand, we replace the backbone network in the original model with resnest network, which enhances the feature extraction capability of the model. On the other hand, we introduce the CBAM convolution attention module to improve the segmentation ability of the model to the target in the foreground region. Without affecting the inference rate of the original model, the training effect of the improved idea proposed in this paper on the cityscapes open data set is improved separately from 71.0% to 71.3% and 71.9%. Respectively compared with the MIoU of the baseline model, the MIoU of the icnet model combined with the resnest backbone network and the CBAM convolution attention module on the cityscapes open data set is increased from 71.0% to 72.1%, and the segmentation effect of the foreground area target is significantly optimized in the visualization images, which has certain positive significance for the application of the semantic segmentation algorithm in the field of unmanned driving. © 2023 IEEE.

Smart Grids (SG) rely on Home Area Networks (HAN) and Neighborhood Area Networks (NAN) to ensure efficient power distribution, real-time monitoring, and seamless communication between smart devices. Despite these advantages, the use of public communication channels in HAN and NAN networks introduces critical challenges, such as vulnerability to impersonation, physical tampering, and scalability issues in resource-constrained environments. These issues compromise the stability, reliability, and security of SG environments. Existing protocols often fail to adequately address these challenges, particularly in ensuring resistance to physical tampering of supply lines and impersonation attacks. Additionally, they struggle to minimize the computation, communication, and energy costs associated with securing a resource-constrained SG environment. Therefore, we propose a robust key exchange and tamper-resistant protocol for HAN and NAN networks to address these limitations. The proposed protocol leverages the Physical Unclonable Function (PUF) mechanism to offer physical tampering resistance to smart meters. We validate our protocol formally using the Random or Real (RoR) model, which confirms its security robustness. Additionally, our informal security analysis highlights the protocol's resilience against impersonation, physical tampering attacks, etc. We analyze and compare the performance of the proposed protocol, which further demonstrates our protocol's effectiveness and security compared to competing protocols. Moreover, the proposed protocol achieves resource efficiency with 45.99% and 58.85% substantial reductions in computation overhead and energy overhead, respectively, compared to competing protocols. These results showcase the protocol's enhanced security and practicality for resource-constrained SG environments. © 2014 IEEE.

Deploying task caching at edge servers has become an effectiveway to handle compute-intensive and latency-sensitive tasks on the industrialinternet. However, how to select the task scheduling location to reduce taskdelay and cost while ensuring the data security and reliable communicationof edge computing remains a challenge. To solve this problem, this paperestablishes a task scheduling model with joint blockchain and task cachingin the industrial internet and designs a novel blockchain-assisted cachingmechanism to enhance system security. In this paper, the task schedulingproblem, which couples the task scheduling decision, task caching decision,and blockchain reward, is formulated as the minimum weighted cost problemunder delay constraints. This is a mixed integer nonlinear problem, which isproved to be nonconvex and NP-hard. To solve the optimal solution, thispaper proposes a task scheduling strategy algorithm based on an improvedgenetic algorithm (IGA-TSPA) by improving the genetic algorithm initializationand mutation operations to reduce the size of the initial solutionspace and enhance the optimal solution convergence speed. In addition,an Improved Least Frequently Used algorithm is proposed to improve thecontent hit rate. Simulation results show that IGA-TSPA has a faster optimalsolution-solving ability and shorter running time compared with the existingedge computing scheduling algorithms. The established task scheduling modelnot only saves 62.19% of system overhead consumption in comparison withlocal computing but also has great significance in protecting data security,reducing task processing delay, and reducing system cost.
