However, rPPG signals are inherently weak and exhibit regional variations across facial areas. Accurate heart rate estimation necessitates analysis of extended-duration video sequences (exceeding 100 frames). To address these challenges, this paper proposes a novel deep neural network (DNN) based on self-attention mechanism, named spatial–temporal self-attention network (STSA-Net). This convolution-free DNN primarily adopts a transformer architecture. Initially, differential processing is applied to the input video to accentuate frame-to-frame variations and amplify subtle rPPG signals. These differential frames are subsequently passed through a spatial self-attention encoding module. This module models spatial dependencies within facial regions, allowing the network to focus on informative areas while suppressing irrelevant noise. Following spatial encoding, the features are processed by a temporal self-attention module, which captures long-term dependencies across frames using transformer-based techniques. The proposed method is rigorously evaluated through comprehensive experiments, including ablation studies, intra-database evaluations, and cross-database comparisons, using three benchmark databases: UBFC-RPPG, PURE, and MAHNOB-HCI. Our model demonstrates performance on par with state-of-the-art methods for remote heart rate measurement, achieving a MAE of 0.4 bpm on PURE, 0.48 bpm on UBFC, and 3.75 bpm on MAHNOB-HCI in intra-database experiments, and 1.36 bpm (UBFC<span><math><mo>→</mo></math></span> PURE) and 1.27 bpm (PURE<span><math><mo>→</mo></math></span> UBFC) in cross-database experiments.

This eliminates the need for a costly backpropagation procedure, resulting in a substantial decrease in training time. The integration of VCNN with I-RVFLwoDL utilizes the I-RVFLwoDL’s rapid learning efficency and robust generalization capabilities. I-RVFLwoDL simplifies the network structure by eliminating the complex neuron pathways typically found in other established methodologies.

The 2D-ICCM is designed to exhibit complex dynamic properties and high sensitivity to initial conditions, the chaotic behaviors of which are verified through the Lyapunov exponent, bifurcation diagrams, sample entropy, and 0-1 test. In addition, a cross bit-plane permutation method is proposed to rearrange the bits in high four bit-planes and low four bit-planes, which further increases the complexity of the encryption and provides stronger protection against attacks. In the diffusion process, an independent bit-plane multi-direction diffusion method using a Zigzag scan is proposed.

In this context, this study introduces both linear and nonlinear control algorithms that might be implemented on a grid-connected wind energy conversion system (G-CWECS) to optimize the extraction of the global maximum power point (GMPP) and improve active and reactive power regulation. The foundation of these strategies lies in linear active disturbance rejection control (LADRC), which is well-known for its capability to handle uncertainties and disturbances, relying on its observer. The current-based bidirectional LSTM (CBi-LSTM) and optimum torque control (OTC) MPPT method integrated with LADRC are employed to extract GMP from WECS. A powerful metaheuristic technique, named catch fish algorithm (CFA), is utilized to update the Bi-LSTM weights. The LADRC approach is applied to regulate both active and reactive power by controlling grid currents, ensuring a unity power factor. Matlab simulation and Hardware-In-the-Loop (HIL) experiment are carried out to verify the feasibility of the implementation. Comparing with well-known-MPPT methods, the output outcomes prove the efficiency of the recommended Bi-LSTM-OTC-LADRC regarding GMPP extraction during wind speed variation.

This paper's main goal is to present a new decentralized information flow control system for cloud virtual machines with multiple tenants. Three main elements make up the cloud computing environment: (a) Cloud Service Provider (CSP), (b) Data Store (DS), and (c) User. The Cloud Service Provider (CSP) is embedded with the newly proposed decentralized information flow control, and it enables the flow of control of data policies for regulating the flow of data between the cloud users within the cloud. The proposed technique involves three primary stages (i) data identification (ii) trust evaluation (iii) optimal key-based cipher-text information flow security. Initially, according to the security values, tactful information is derived from the input data, which is secured in the CA of CSP to safeguard the labels and keys authentically, subsequently, the decryption process takes place. Then the EP exhibit the flow of ciphertext data based on the proposed estimation of trust. The proposed improved Signcryption algorithm is employed to cipher the user's information and the optimal key is generated by using the proposed improved Sun Flow Optimization Algorithm, which ensures that data remains confidential and tamper-proof. Ultimately, based on the proposed trust value, a decryption key will be offered to users like direct users and indirect users, in which the direct users are the old users already having access rights whereas the indirect users are the new users.

However, the diversity and resource constraints of IoT devices present ongoing challenges. Existing studies on key agreement often focus on devices with specific conditions and specialized communication models. Their broader applicability is limited by that reason. This study addresses this gap by identifying and compiling the necessary features and conditions for key agreement algorithms in IoT environments.

This paper aims to categorize, analytically and statistically, the current research techniques on key agreement approaches in IoT published from 2016 to 2024. We present three technical taxonomies for the key agreement approaches in IoT based on the content of current studies. Our findings reveal that crucial parameters such as communication models, essential resources, and required tools are often overlooked in current IoT key management approaches. Notably, only 2% of the reviewed algorithms are lightweight and suitable for device-to-device communication models without prerequisites.
