Dentigerous cyst (DC) and keratocystic odontogenic tumor (KOT) are odontogenic lesions arising from epithelial elements, such as those observed in dental follicles (DF), that have been part of the tooth forming apparatus. These lesions show different clinical and histological characteristics, as well as distinct biological behavior. This study aimed to qualify and quantify collagen and elastic ...

Power supply systems in telecommunication applications employ several parallel-connected ac-to-dc and dc-to-dc power converters. Such a system offers modularity, redundancy, and is easily scalable to higher power levels. Such parallel-connected systems normally consist of several single-phase powerfactor-correction (PFC) stages connected to the same input utility. In this paper, a modular singl...

The volume scalability of nonequilibrium plasmas produced by electrical discharges in atmospheric pressure air has been investigated. A variety of direct current (DC) and pulsed glow discharges obtained in either slow flow of ambient or fast flow of preheated (~2000 K) air at atmospheric pressure is presented. Single DC and repetitively pulsed discharges represent the first approach. Stable dis...

This project mainly deals with the study of obtained output power by interfacing multiple wind turbine by using pulse width modulation(PWM) current source wind energy conversion system based on a parallel configuration. This has some of the advantages of the VSC based system, but is inherently robust to both dc and acshort circuit faults. Furthermore, this configuration overcomes some disadvant...

A new approach to the design of decentralised controllers, using Multi-Objective Evolutionary Algorithm (MOEA), for loadfrequency control of interconnected power systems with AC-DC parallel tie-lines and considering Governor Dead Band and Generation Rate Constraint nonlinearities, is proposed in this paper. The HVDC link is used as system interconnection in parallel with AC tie-line to effectiv...

The Mantel Test, discovered in the 1960s, determines whether two distance metrics on a graph are related. We describe DC-RST, an algorithm to accelerate key step of network science statistical computation associated with DimeCost, approach that is faster Test. DC-RST parallel, divide-and-conquer compute random spanning tree complete n vertices. Relative implementation Wilson’s sequential random...

This paper proposes a parallel energy-sharing control for fuel cell electric vehicles (FCEVs) application. The hybrid source consists of a fuel cells (FCs) generator, battery packs and Ultracapacitor (UC) modules. In the proposed parallel energy-sharing control, each source is connected to the direct current (DC) bus via power electronics converters. A total of six control loops are applied in ...

In this paper, the fault current limiting (FCL) characteristics of a flux-coupled type superconducting limiter (SFCL) with parallel connection between two windings in DC system were analyzed. The SFCL was composed coils connected and element (SE), which series secondary coil. works systems similar to those AC systems. Before occurs, respective magnetic fluxes generated by offset each other, mai...
