The early detection of the transformer faults with high accuracy rates guarantees continuous operation power system networks. Dissolved gas analysis (DGA) is a technique that used to detect or diagnose based on dissolved gases due electrical and thermal stresses influencing insulating oil. Many attempts are accomplished discover an appropriate correctly fault types, such as Duval Triangle metho...

In this work, a new and effective algorithm called hybrid teaching–learning-based optimization (TLBO) charged system search (CSS) algorithms (HTC) are proposed to solve engineering mathematical problems. The CSS is inspired by Coulomb Gauss’s electrostatic laws of physics as well the Newtonian mechanic motion. TLBO interaction between teacher student in classroom. Usually, gets trapped local op...

This paper presents an improved Teaching-Learning-Based Optimization (TLBO) for optimal tuning of power system stabilizers (PSSs) and static VAR compensator (SVC)-based controllers. The original TLBO is characterized by easy implementation mainly free control parameters. Unfortunately, may suffer from population diversity losses in some cases, leading to local optimum premature convergence. In ...

Non-orthogonal multiple access (NOMA) and coordinated multi-point (CoMP) are two fundamental techniques considered for the fifth generation (5 G) of wireless communications. In this paper, a hybrid satellite-unmanned aerial vehicle (UAV) relay network (HSURN) is proposed where UAV relays (URs) employ CoMP transmission to serve terrestrial users (UEs). Furthermore, all UEs associated with CoMP-U...

In this work, the process of dissimilar resistance spot welding (RSW) for AISI 304 and 1060 steel sheets is experimentally investigated. The effects main parameters such as current, electrode force, cycle, cooling cycle on tensile-shear strength (TSS) RSW joints are studied. To aim, using a central composite experimental design based response surface methodology (RSM), tests were performed. Fur...

Developing new optimization algorithms and data mining has improved traditional engineering structural analysis models (meaning basically swarm-based solutions). Additionally, an accurate quantification of in situ friction capacity (ISFC) driven piles is paramount importance design/construction geotechnical infrastructures. A number studies have underscored the use developed via artificial neur...

This article proposes an intelligent control strategy to enhance the frequency dynamic performance of interconnected multi-source power systems composing thermal, hydro, and gas plants high penetration level wind energy. The proposed is based on a combination fuzzy logic with proportional-integral-derivative (PID) controller overcome PID limitations during abnormal conditions. Moreover, newly a...

The Internet of Things (IoT) is a network numerous devices that are consistent with one another via the internet. Wireless sensor networks (WSN) play an integral part in IoT, which helps to produce seamless data highly influence network’s lifetime. Despite significant applications several challenging issues such as security, energy, load balancing, and storage exist. Energy efficiency considere...
