The damping of inter-area oscillations is an important problem in electric power systems (Klein et al., 1991; Kundur, 1994; Rogers, 2000). Especially in China, the practices of nationwide interconnection and ultra high voltage (UHV) transmission are carrying on and under broad researches (Zhou et al., 2010), bulk power will be transferred through very long distance in near future from the viewp...

Unconscious processing has been convincingly demonstrated for task-relevant feature dimensions. However, it is possible that the visual system is capable of more complex unconscious operations, extracting visual features even when they are unattended and task irrelevant. In the current study, we addressed this question by measuring unconscious priming using a task in which human participants at...

In recent years, a great need for large scale servers has arisen. One practical solution is to construct such servers as cluster systems. For applications reside on them, inter process communications(IPCs) among them must be high performance. The current generation of System Area Networks(SANs) have very wide bandwidths, and very low communication latencies, and they usually consume relatively ...

Large distributed storage systems use erasure codes to reliably store data. Compared to replication, erasure codes are capable of reducing storage overhead. However, repairing lost data in an erasure coded system requires reading from many storage devices and transferring over the network large amounts of data. Theoretically, Minimum Storage Regenerating (MSR) codes can significantly reduce thi...

the present study aimed at investigating the specific discourse cycles of someintroductory textbooks across disciplines and languages to see to what extent theyacculturate students into the new subjects. to this end, 2 well-established and mostlyused english and persian introductory textbooks in sociology and 2 other wellestablishedenglish and persian introductory textbooks in linguistics were ...

objective: in view of the effect of hard labor on pregnancy outcomes and to determine risk factors, in this study, the effect of spacing between pregnancies was evaluated for probable effect on the incidence of dystocia in labor. materials and methods: this is a cross - sectional study used the records of 210 pregnant women referred to azad university hospitals between january 2000 and december...

A field experiment was conducted at wondo genet Agriculture research center under irrigated condition to determine the effect of intra and inter-row spacing on growth and yield of Artemisia (Artemisia annua L.) during the two successive seasons of 2013 and 2014. Factorial combinations of four intra-rows (40, 60, 80, 100 cm) and four inter-row plant spacing’s (60, 80, 100, 120 cm) were laid out ...

Multicast trees can be shared across sources (shared trees) or may be source-speciic (shortest path trees). Inspired by recent interests in using shared trees for interdomain mul-ticasting, we investigate the trade-oos among shared tree types and source speciic shortest path trees, by comparing performance over both individual multicast group and the whole network. The performance is evaluated ...

The wireless systems entered a phase characterized by the integration of the existing platforms into hybrid access wireless IP architectures. The requests of the real time applications ran in heterogeneous environments need the presence of a mechanism for resource negotiation and management. The paper suggests the design and implementation of an inter-domain QoS mechanism in a hybrid access wir...
