Background: When conventional petroleum-based liquid fuels are combusted, several hazardous pollutants are produced. These pollutants are noxious for both human beings and the environment. Objective: This study aims to analyze the stability of Hydrogen-CNG powered vehicles. Hydrogen has the potential to be one of the most sustainable fuels of the future, decrease the global dependence on fossil fuel resource Read More

Background: The Sensor Nodes (SNs) are deployed in an environment where human beings are not able to perform the tasks. Wireless Sensor Network (WSN) is used for applications in security, military surveillance, habitat monitoring, agriculture, etc. All these applications require SNs to have good battery backup so that they can perform for a long duration. Recent research shows that agent-based strategies increase th Read More

Background: Harmonic resonance is one of the apprehensive power quality problems in electric railway traction power supply systems. Harmonic resonances result in big harmonic voltage distortions or harmonic currents. Different harmonic resonance frequencies existing in a power system possess varying propagation areas and amplification levels. The frequency scan analysis technique and the resonance mode analysis te Read More

This paper focuses on designing and modeling multiple-output wireless chargers for electric vehicles (EVs). This paper uses a closed loop buck converter to obtain variable output dc voltage of a wireless electric vehicle charger (WEVC). For designing a closed-loop buck converter, a PI controller is used. The tuning of a PI controller for a nonlinear system is a typical task; therefore, in the paper, three optimization techni Read More

Background: In this paper, a new frequency-selective structure (FSS) for 3 to 4 GHz frequency band of fifth generation (5G) is proposed as a result of an analytical mode-matching method. Methods: A new periodic structure with stepped rods is designed using a closed-form equation derived by the analytical mode-matching method. Performance of the structure is simulated by different numerical packages. Results: The analytic Read More

Background: The research in this paper aims to address the effect of large-span AC lines on ion currents in parallel DC lines. This paper proposes an algorithm for solving mixed ion flow fields based on meshless radial point interpolation, which can accurately solve the ion flow field of large-span AC-DC parallel lines. Methods: The shape function of the traditional meshless method is modified by polynomial radial point interpolation Read More

Introduction: In order to solve the problems of time-consuming and poor effects of traditional mechanical vibration control methods for the relay, the mechanical characteristics and vibration control of railway signal relays are studied in this paper. Based on the analysis of the mechanical characteristics of railway signal relays, the mechanical characteristic parameters of the relay, such as contact force, initial pressure, co Read More

Background: Facial emotion recognition (FER) is a vital research area in machine vision and artificial intelligence due to its application in academics and industry. Although FER can primarily be conducted using multiple sensors, research shows that using facial images/videos to recognize facial expressions is a better way to convey emotions because visual expressions carry essential information. Objective: This paper focuses on Read More
