Abstract With the rapid development of telecommunication networks, predictability network traffic is significant interest in analysis and optimization, bandwidth allocation, load balancing adjustment. Consequently, recent years, research attention has been paid to forecasting traffic. Telecommunication problems can be considered a time‐series problem, wherein periodic historical data fed as input model. Time‐series approaches are broadly categorized statistical machine learning (ML) methods...
Home energy management requires accurate information about the appliances' consumption pattern. This can help consumers save energy, control their usage by shifting to off-peak hours and reduce electricity costs. Non-intrusive load monitoring (NILM) in which power profile of appliances are extracted from aggregated signal a household, provides this information. For NILM problem, machine learning approaches as training-based solutions require large training datasets for an disaggregation...
Extensive research has focused on enhancing the efficiency and stability of robotic arms. Sliding mode control (SMC) is commonly used in industrial robots due to its robustness simplicity. However, SMC approaches have challenges such as chattering slow convergence rates which can compromise tracking accuracy. To address these issues, this paper proposes a novel Super-Twisting Fast Non-singular Terminal Mode Control (ST-FNTSMC) strategy for 3-DOF arm robot. The proposed approach significantly...
Abstract Deep learning-based approaches for diagnosing bearing faults have attracted considerable attention in the last years. However, real-world applications, these methods face challenges. For proper training of models, a amount labeled data are necessary, and due to limitations industry, obtaining this may not be possible. Because load variations, distribution test vary, which reduces accuracy trained model various working conditions. Furthermore, noise has significant impact on fault...
In this paper, we introduce a distributed secondary frequency control scheme for an islanded ac microgrid under event-triggered communication.

Synchronization between two coupled complex networks with fractional-order dynamics, hereafter referred to as outer synchronization, is investigated in this work. In particular, we consider systems consisting of interconnected nodes. The state variables each node evolve time according a set (possibly nonlinear and chaotic) differential equations.

In this paper, a robust fractional-order controller is designed to control the congestion in transmission protocol (TCP) networks with time-varying parameters. Fractional controllers can increase stability and robustness. Regardless of advantages fractional controllers, they are still not common TCP networks. The network parameters time-varying, so important design. Therefore, we focused on PID developed based active queue management (AQM). D-partition technique used. most property...
