Line and load transients are step functions that inject disturbances into the power supply. A load transient injects disturbance into the output by stepping the load current, and a line transient does so by stepping the line voltage. The supply’s output response demonstrates its ability to attenuate the various frequency components of a line or load step. The following discussion describes thes...

the aim of this study was to determine the monthly dtr mass load of amphetamine-type compounds in poland as well as an investigation of cyclical behaviour by using time series analysis and especially trends analysis.amphetamine, methamphetamine and mdma (ecstasy) were detected in wastewater samples collected from the main wastewater treatment plant in the city of poznan using liquid chromatogra...

– A sample transmission line, which is laid at the bottom of the GUI. There is a slider in the line that indicates the position of measurement probes. The probes are measuring the information of the line, toward the load. By default, the probe is laid next to the load. Thus the initial impedance, measured by the probe is the same as the load. It is possible to enter desired values as a load. Un...

Load balancing algorithms improve a program’s performance on unbalanced datasets, but can degrade performance on balanced datasets, because unnecessary load redistributions occur. This paper presents a cost-effective data-parallel load balancing algorithm which performs load redistributions only when the possible savings outweigh the redistribution costs. Experiments with a data-parallelpolygon...

We consider the problem of schedulingpermanent jobs on related machines in an on-line fashion. We design a new algorithm that achieves the competitive ratio of for the deterministic version, and for its randomized variant, improving the previous competitive ratios of 8 and ! " # . We also prove lower bounds of $ on the competitive ratio of deterministic algorithms and % on the competitive ratio...

the graphical technique for nonlinear circuits was described that enable us to optimize circuits to obtain maximum output power, maximum efficiency or minimum intermodulation. according to this method a high power amplifier in the ka band was designed. using a nonlinear model of the transistor, optimum slope for load-line was determined so that maximum power at the output was obtainable, then ...

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 ...

Total transfer capability TTC is an important index in a power system with large volume of inter-area power exchanges. This paper proposes a novel technique to determine the TTC and its confidence intervals in the system by considering the uncertainties in the load and line parameters. The optimal power flow OPF method is used to obtain the TTC. Variations in the load and line parameters are in...
