In this paper, the performance of two types of FACTS devices in order to enhance the power system static voltage stability has been investigated. These devices include Static Var Compensator (SVC) and Thyristor Controlled Series Capacitor (TCSC). The modeling of the Single Machine Infinite Bus (SMIB) and aforesaid devices has been made up in steady state mode with disregarding of the generator ...
BACKGROUND In high-income countries, viral load is routinely measured to detect failure of antiretroviral therapy (ART) and guide switching to second-line ART. Viral load monitoring is not generally available in resource-limited settings. We examined switching from nonnucleoside reverse transcriptase inhibitor (NNRTI)-based first-line regimens to protease inhibitor-based regimens in Africa, Sou...
conclusions it seems that, the preventive instructions are not optimally respected by ers possibly due to the crowded wards, high work load and the need to work rapidly. results cleaning blood tainted skin before phlebotomy or iv line preparation and hand washing before donning latex gloves achieved the maximum (88/150) and minimum (0/150) scores. the most observed barriers of pm were frequent ...
the management of sedimentation problems in rivers and reservoirs depend greatly on the sediment yield from the catchment land surface. in this research the effects of biological measures and ranges enclose on suspended load in two sub-catchments of kakhk experimentalwatershed in gonabad has been studied. this catchment contains both control and experimental sub-catchments. these sub-catchments...
The map overlay-operation is one of the most important and most time consuming operations in the Geographic Information System. In general, a map consists of a huge number of line segments. The major cost for overlaying two maps is that of computing the intersection points between the line segments. Parallel processing is one of the ways to reduce the computing time. If one can partition the li...
In this paper a hybrid active DC line conditioner for fluctuations and ripples reduction in voltage and current of DC power systems is proposed. Malfunctions in operation of equipments and systems which are supplied by low quality distribution power systems are one of the main effects of DC voltage ripple. In the proposed configuration a hybrid system including series and shunt active line ...
In this paper, buckling behavior of functionally graded carbon nanotube-reinforced composite (FG-CNTRC) plates is studied in line with the plates thikness. All governing equations are presented incrementally, based on a First-order Shear Deformation Theory (FSDT) of plates and von Karman strain field. In order to find the critical buckling load, the axial load is applied to the plate incr...
In this paper, a new principle for an adaptive line driver using Fuzzy logic is presented. This type of line driver can adapt its output impedance and gain, automatically to the applied load using a fuzzy logic controller (FLC). This results in automatically corrected output impedance for different cables with terminations. Also, the line driver output impedance and gain become insensitive to p...
Currents are established on the surface of conductors by the propagation of electromagnetic waves in the insulating material between them. If the load is less than the characteristic impedance of the line, multiple reflections and retransmissions eventually build up the line current to that required by the load. The currents are initially established on the surface of the conductors before diff...
This paper gives new methods for calculating the time-domain response for a nite-length distributed RC line. We begin with the solution for di usion in a semi-in nite distributed RC line [4, 12] and apply the method of images (re ections) to obtain the voltage response for a nite-length RC line. Second, we describe a general approach for calculating the time-domain response for nite RC lines wi...
