The EVs battery has the ability to enhance the balance between the load demand and power generation units. The EV aggregators to manage the random behaviour of EV owners and increasing EVs participation in the ancillary services market are employed. The presence of aggregators could lead to time-varying delay in load frequency control (LFC) schemes. The effects of these delays must be considere...

background non-alcoholic fatty liver disease (nafld) is considered as the hepatic manifestation of insulin resistance (ir) syndrome. the effect of insulin sensitizers on liver function tests and metabolic indices in nafld patients is a matter of debate. objectives the aim of study was to compare the effects of two different insulin sensitizers, pioglitazone, and metformin, on liver function tes...

Load frequency control (LFC) is one of the significant ancillary services in the electricity markets. The major concerns with LFC models have long been their dynamic response and complexity, as well as market price sensitivity. To cater to the complexity of the dynamic model that is introduced by the LFC and algebraic constraints by the transmission network, the differential-algebraic equation ...

In this paper the problems of market monitoring and control of ancillary services of a future energy systems are presented. We envision that future system operation of electric power systems will evolve into completely unbundled ancillary service markets that are governed by spot price signals. The grid operators need to acquire ancillary services through competitive markets for control of the ...

A set of killer whale sounds from Marineland were recently classified automatically [Brown et al., J. Acoust. Soc. Am. 119, EL34-EL40 (2006)] into call types using dynamic time warping (DTW), multidimensional scaling, and kmeans clustering to give near-perfect agreement with a perceptual classification. Here the effectiveness of four DTW algorithms on a larger and much more challenging set of c...

Abstract For a long time, research on the pre-Han (before 202 BCE) Chinese use of lost-wax process was targeted at demonstrating that it no all. That position severely shaken when zun-pan set Zeng Hou Yi (“Marquis Zeng,” d. 433 unearthed Hubei Suizhou in 1978, along with subsequently excavated finds or rediscovered artifacts carrying similarly interpenetrating openwork. Since early 2000s, howev...
