harmonics have become an important issue in modern power systems. the widespread penetration of non-linear loads to emerging power systems has turned power quality analysis into an important operation issue under both steady state and transient conditions. this paper employs an extended harmonic domain (ehd) based framework for dynamic analysis of long term analysis over voltages during the tra...

this paper addresses the problem of the fractional sliding mode control (fsmc) for a mems optical switch. the proposed scheme utilizes a fractional sliding surface to describe dynamic behavior of the system in the sliding mode stage. after a comparison with the classical integer-order counterpart, it is seen that the control system with the proposed sliding surface displays better transient per...

This paper presents the determination of power transfer between two buses that takes into account the dynamic security constraint. The dynamic security constraint based transient stability has been found to be one of the limiting factors in determining the power transfer so-called as the available transfer capability (ATC). The multimachine integral square generator angle (ISGA) index is used t...

Dynamic response of a converter plays an important role in many applications which change load in a rapid manner, especially in PoL(Point of load)applicat ions. Here a new method for improving the dynamic response of a converter is presented. Here separate control schemes are implemented during steady state as well as transient load conditions. A three level buck converter topology with fast tr...

conclusions carriage of pvl-positive s. aureus is common in this region, even in the low frequency of mrsa colonization. the detection of acme-arca gene in s. aureus isolates is a public-health concern and demands continued surveillance and close monitoring. results among the 813 subjects screened, 83 (10.2%) were persistent carriers, 86 (10.6%) were transient carriers and 644 (79.2%) cases wer...

Many control schemes have been proposed for induction motor and permanent magnet synchronous motor control, which are almost highly complex and non-linear. Also, a simple and efficient method for unified control of the electric moto are rarely investigated. In this paper, a novel control method based on rotor flux orientation is proposed. The novelties of proposed method are elimination of q-ax...

Dynamic, dissipative reactions play important roles in biological processes, and emulating such processes by artificial circuits networks is a challenging topic the area of Systems Chemistry. The present article summarizes efforts to apply information encoded base sequence nucleic acids assemble transient, DNA-based mimicking natural processes. design principles transient acid-based systems are...

A mathematical model is formulated, and a numerical study of magneto-plasma compressor (MPC) discharges in gases for wide range changes the main electrical parameters characteristics surrounding gas environment carried out. The performed calculations showed, depending on role one or another heating mode (Ohmic, transient, plasma dynamic), three different types quasi-stationary spatial distribut...
