the purpose of this study is to investigate the effect of injection parameters on a heavy duty diesel engine performance and emission characteristics. in order to analyze the injection and spray characteristics of diesel fuel with employing high-pressure common-rail injection system, the injection characteristics such as injection delay, injection duration, injection rate, number of nozzle hole...

Problem statement: Modern power system consists of the complicated network of transmission lines and carries heavy demand. Thus they cause in the stability problem. Approach: Static Synchronous Series Compensator (SSSC) is a power electronic based device that has the capability of controlling the power flow through a line. The series voltage injection model of SSSC is modeled into power flow eq...

A considerable progress has been achieved in transient stability analysis (TSA) with various FACTS controllers. But, all these controllers are associated with single transmission line. This paper is intended to discuss a new approach i.e. a multi-line FACTS controller which is interline power flow controller (IPFC) for TSA of a multi-machine power system network. A mathematical model of IPFC, t...

The FACTS (Flexible AC Transmission System) devices have been considered as excellent controllers in a power system for better reliability and transmission capacity on a long-term and cost-effective basis. In this paper, a novel power flow controller topology is proposed for FACTS in order to improve static voltage stability characteristics and loading margin enhancement. Employing hybrid topol...

This paper presents an ultra-wideband injection-locked frequency divider (ILFD) design which is applicable to a multi-applications system. A transformer-based multi-order resonator utilized in the ILFD attain flat phase response. The passive injection-boosted technique proposed increase injection signal amplitude and thus widen locking range. With resonator, demonstrates measured range of 50GHz...

Sathishkumar*** Department of Electrical and Electronics Engineering, Gnanamani College of Technology, Tamilnadu Abstract: Due to the merits of sinusoidal input currents and excellent conversion efficiency, buck-type active third-harmonic injection converters have received increasing attentio...

BACKGROUND Liquid needle-free injection devices (NFIDs) employ a high-velocity liquid jet to deliver drugs and vaccine through transdermal injection. NFIDs for animal vaccination are more complicated than those used for human beings for their much larger and more flexible power sources, as well as rapid, repetitive and continuous injection features. METHOD In the paper, spring-powered NFID is...
