The reactive diffracting trees are known efficient distributed data structures for supporting synchronization. They not only distribute a set of processes to smaller groups accessing different parts of the memory in a global coordinated manner, but also adjust their size in order to attain efficient performance across different levels of contention. However, the existing reactive adjustment pol...

This paper presents a novel control approach used in shunt active power filter based on variable structure control combined with Random PWM technique (RVSC) that provides robust, fast, and more favorable performance for active power filter. This control strategy is compared with two other strategies to show the effectiveness of the introduced methods; pulse width modulated proportional-integral...

Geometric iterative method, also called progressive-iterative approximation (PIA), is an iterative method with clear geometric meaning. Just by adjusting the control points of curves or surfaces iteratively, the limit curve or surface will interpolate (approximate) the given data point set. In this paper, we introduce the geometric iterative method in two aspects, i.e., theory and application. ...

In this paper we present a novel subdivision scheme that can produce a nice-looking interpolation of the control points of the initial polyline, giving the possibility of adjusting the local shape of the limit curve by choosing a set of tension parameters associated with the polyline edges. If compared with the other existing methods, the proposed model is the only one that allows to exactly re...

The Photovoltaic (PV) system is an eco-friendly renewable energy that integrated with a DC-DC buck-boost converter to generate electrical as per the variations in solar irradiance and outdoor temperature. This article proposes novel Adaptive Fractional Order PID (A-FOPID) compensator self-adjusting fractional orders extract maximum power from stand-alone PV ambient conditions change. reference ...
