This paper presents the comparative evolutionary optimization techniques to optimize the design and implementation of the walking pattern generator (WPG) permitting the biped robot able to stably walking with pre-set hip-shift magnitude. The novel jaya optimization algorithm is initiatively applied and comparatively investigated with four different efficient evolutionary optimization techniques including Genetic algorithm (GA), Particle Swarm optimization (PSO), Modified Differential Evolution (MDE), and Central Force optimization (CFO). The comparative performance of five optimization techniques applied on the generic small-sized nonlinear uncertain biped robot (HUBOT-5) comprehensively considered by executing each technique 10 times with the same initial parameters. Using obtained results, it gives the best evolutionary optimization approach for optimize the walking gait generator applied for allowing a stable walking with pre-set hip-shift value. Simulation and experimental results on biped robot HUBOT-5 prove that the jaya optimization algorithm is most feasible.

This paper presents a generalized technique for unique selection of both phase shifts of dual phase shift (DPS) control of DAB. The technique is basically used to minimize the peak current stress while maintaining required amount of power flow with soft switching. For optimizing the current stress at different voltage conversion ratio, multi-objective, multi-constraint jayaalgorithm is used. This algorithm basically uses unified current stress as the objective function with mathematical expression of unified power flow is the equality constraint and phase shift boundaries are inequality constraint. This control flow not only provided unique selection criterion for phase shift with minimized current stress but also the phase shift selection considers soft switching performance under all loading conditions. It shows the simulation as well as experimental results on a 1.5 kW designed system. The results are taken with voltage conversion ratio 'K=V-1/NV2' varying from 1 to 0.28 under different loading condition. From obtained results it is shown that when voltage conversion ratio is K=1, then no extra increment in peak of series inductor current. When K=0.28 there is slightly increment in peak of series inductor current. A detailed Simulink control flow model is shown with its closed loop DSP experimental implementation. This model is designed for the control of dual active bridge based off-board charging system.

Direct current (DC) motor plays an important role in industries to convert energy from electrical to mechanical. The speed of DC motor is important in the process control industries so we have to control the speed of DC motor. For this speed control proportional-integral-derivative (PID) controllers are used. For better performance and optimum parameters, PID tuning is used. Traditional tuning techniques for classical PID controller suffer from many disadvantages like non-customized performance measure and insufficient process information. In this paper, we use the jaya optimization algorithm (JOA) for better performance in speed control and time response of the system. Experimental results are presented to study the performance of JOA based PID controller in comparison with particle swarm optimization (PSO) based PID controller. Practical validation is done on QNET 2.0 DC motor by using LabVIEW (R) software.

Ransomware is a serious security concern to mobile devices, as it prevents the use of the device and its contents until a ransom is paid, resulting in considerable financial losses for both people and corporations. The existing anti-malware measures have shown to be inadequate in combatting new malware variants that utilize advanced evasion strategies like Polymorphic, Metamorphic, Dynamic Code Loading, Time-based evasion, and Reflection. Furthermore, these primary defences have also suffered from low detection rates, significant false positives, high processing times, and excessive processing and power consumption that is inappropriate for smartphones. This paper offers the binary jaya (Bjaya) for ransomware detection in Android mobile devices using the Bjayaoptimization-based algorithm. The developed algorithm's effectiveness has been assessed against two datasets, the 0-1 knapsack, and real ransomware dataset. The proposed Bjaya method surpassed the other algorithms on 85% of the 0-1 knapsack datasets. The suggested Bjaya method was also tested on a ransomware dataset in two phases. In the first stage of testing, Bjaya outperformed other standard classifiers with sensitivity and Gmean values of 97% and 98.2%, respectively. In the second stage of testing, Bjaya outperformed other GA, FPA, and PSO metaheuristic algorithms in terms of specificity, sensitivity, and Gmean. These findings indicate the applicability of the suggested Bjayaalgorithm for ransomware detection.

This paper is concerned with the application of hybrid fuzzy-jaya optimization algorithm to find the solution of non-linear optimal reactive power dispatch (ORPD) problem in power systems. The proposed hybrid optimizationalgorithm combines the merits of fuzzy principle and the jaya optimizer. Fuzzification of the ORPD variables is employed by pseudo goal strategy. Two technical objectives are minimized individually and simultaneously to enhance the overall power systems performance. These objectives are transmission active power losses and voltage deviation at load buses. The ORPD objectives are optimized considering both inequality and equality constraints that reflect the operation needs. The hybrid fuzzy-jaya is established as efficient optimization method that is achieving the global optimal solution. The effectiveness of the proposed hybrid algorithm for solving the ORPD problem is proven by using three standard IEEE test networks. An assessment of the proposed hybrid algorithm is carried out compared with other optimizationalgorithms those reported in the literature. The simulation results assure that the fuzzy jaya hybrid algorithm leads to significant power system performance enhancement for different scale power systems.

The continual increase in the power network topological structure and long distances between load-generation sources lead to modern powers systems are operated near theirs stability margins. For this issue, reliable and secure operations of electric devices through inter-area oscillations remain an essential issue in the system dynamic stability. In the case of improper actions of controlling devices, the severe inter-area interactions may lead to wide-area instabilities and large blackouts. Using wide-area measurement system (WAMS), remote signals are transferred through communications links with different inherent time latencies. In the case of large time delays, the main controllers cannot work appropriately which leads to improper performance of damping controllers through severe inter-area fault event scenarios. For this issue, this paper presents an adaptive wide-area damping controller (AWADC) for damping inter-area oscillations in large power systems equipped with WAMS technology consisting of various time latencies. In this case, based on the IEEE C37.118.1 protocol, the generator buses are equipped with phasor measurement unit devices. Also, owing to the different communication links, the measured global signals (GSs) are involved within different time latencies. In this case, at each time window, considering time delay compensator (TDC) technology provided through Simevents discrete event tool, the overall time delay is evaluated and compensated. For identifying the best controlling GSs, considering two observability and controllability concepts, the system dynamic signals are evaluated which the best input decisioning signals and corresponding output controlling signals are provided. The proposed AWADC scheme consists of different compensating blocks which are adjusted through simple and well-known jaya optimization algorithm (JOA) through online evaluations. The structure of the proposed AWADC controlling scheme is carried out on a modified 39-bus New E

Aiming at the problem of large location errors of traditional ranging-free algorithms in Wireless Sensor Network (WSN), a novel node location algorithm based on proximity-distance mapping (PDM) and jayaoptimization was proposed. In this algorithm, proximity and Euclidean distance are extracted from the relationship of anchor nodes to construct a mapping matrix by using the idea of PDM. It is calculated by using the mapping matrix that the estimated distance from the unknown node to the anchor node can be used for the subsequent calculations. After the estimated distance is obtained, the jaya optimization algorithm is imported to calculate the location of the unknown one. To accelerate the convergence and enhance the accuracy of the algorithm, the idea of a boundary box is used to limit the initial feasible region of unknown nodes. The experiment results show that the PDM-jayaalgorithm has better positioning accuracy than the original PDM in the same condition.

This article proposes a new method used to optimize the design process of nature-walking gait generator that permits biped robot to stably and naturally walk with preset foot-lift magnitude. The new jaya optimization algorithm is innovatively applied to optimize the biped gait four key parameters initiatively applied to ensure the uncertain nonlinear humanoid robot walks robustly and steadily. The efficiency of the proposed jaya-based identification approach is compared with the central force optimization and improved differential evolution (modified differential evolution) algorithms. The simulation and experimental results tested on the original small-sized biped robot HUBOT-4 convincingly demonstrate that the novel proposed algorithm offers an efficient and stable gait for humanoid robots with precise height of foot-lift value.

Internet of Things (IoT) security is paramount for enterprises, as it includes several strategies, techniques, actions, and protocols that aim to alleviate the high vulnerability of cutting-edge businesses. IoT consumer devices, from smart home appliances to wearable gadgets, have become ubiquitous daily, facilitating automation and seamless connectivity. However, ensuring their reliability and security presents a tremendous challenge. Anomaly detection methods offer a promising solution, especially those powered by TinyML (Machine Learning (ML) on Tiny Devices). These IoT devices can autonomously identify unusual behaviours or patterns that diverge from regular operation by leveraging the proficiencies of deep learning (DL) techniques enhanced for resource- constraint environments, like neural networks. Incorporating DL, anomaly detection, and TinyML allows realtime monitoring and proactive mitigation of malfunctions or security breaches in IoT devices. This advanced technology ensures improved reliability, privacy, and overall user experience in the dynamic landscape of connected devices, whether identifying irregular health data or detecting unauthorized access attempts on a smart door lock from the wearable fitness tracker. Therefore, this study develops a new Deep Learning technique to secure IoT consumer devices with TinyML Driven Real-time Anomaly Detection for Predictive Maintenance (DLTML-RTADPM). The DLTML-RTADPM technique aims to recognize and categorize the anomalies in IoT consumer devices. At the primary phase, the DLTML-RTADPM model normalizes the input data using Z-score normalization. In the DLTML-RTADPM method, the Fennec Fox optimizationalgorithm (FFA) is used for a high dimensionality reduction process where the optimal feature set is chosen. The DLTML-RTADPM technique implements gradient least mean squares with a bidirectional long short-term memory (GLMS-BiLSTM) approach for anomaly detection. To further improve the detection results of the DL
