In microgrids, intermittency of renewable energy sources (RES) and uncertain state-of-charge (SoC) storage systems (ESS) can cause power deficiency to some distributed generation units (DGs). this case, DGs with may not meet the demand, resulting in voltage collapse or frequency divergence. Unfortunately, is seldom considered inverter control design existing literature. Thus, in-depth investiga...

This paper describes the design of a study of visitors to a science museum who are equipped with wirelessly connected handheld devices. The museum exhibits are augmented with information and services in the form of web pages, and the users can access those pages conveniently when in the proximity of the exhibits as well as from their desktops outside the museum. The goal of the study is to exam...

A virtual impedance-based flying start considering transient characteristics for permanent magnet synchronous machine drive systems is proposed. The conventional based on resistance (VR) assumes that the load of system resistive. However, maximum value VR, which determined by parameter and sampling frequency, sometimes small. In this case, non-resistive. This assumption error causes an estimate...

Introduction: Electrical impedance of tissues on low frequencies includes useful information about functional and structural changes in tissues. This property is used in Electrical Impedance Tomography (EIT) imaging modality for the detection of lesions in tissues.Objective: The goal of this article is to study changes in electrical impedance of tissues in the presence of gold nanoparticles.Mat...
