In this paper, the problems of market monitoring and control of ancillary services of 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 s...

The aim of this study was to investigate the effect of group size and stocking density on the welfare and performance of hens housed in furnished cage systems during summer. A total of 924 Hy-Line Brown hens were assigned to three housing systems: a standard battery cage system (control, 4 hens per cage and 398 cm per hen), two furnished systems (including perches and nest); one with a small (S...

The lateral frontal cortex (LFC) is thought to represent contextual and rule-based information that allows adaptive behavior according to circumstance. Recent progress has suggested that the representations of the LFC vary along its rostral-caudal axis with more abstract, higher level representations associated with rostral areas of the LFC and more concrete, lower level representations associa...

Investigations of the cellular and connectional organization of the lateral frontal cortex (LFC) of the macaque monkey provide indispensable knowledge for generating hypotheses about the human LFC. However, despite numerous investigations, there are still debates on the organization of this brain region. In vivo neuroimaging techniques such as resting-state functional magnetic resonance imaging...

This experiment was conducted to determine whether increasing the net energy (NEL ) of a total mixed ration (TMR) with mainly unsaturated fat from corn distillers dried grains with solubles (DDGS) vs. rumen inert (RI)-saturated fat has similar impacts on animal performance. The experiment was an incomplete Youden square with three treatments and four 28-days periods, completed on a large commer...

Lagrangian flux through a fixed curve segment within a time interval (tn, tn + k) can be formulated as an integral at the initial time tn over a compact point set called donating region, in which each particle will pass through the curve during the time interval and contribute to the flux. Based an explicit, constructive, and analytical solution of the donating region, the author proposes algor...

The objective of this paper is to investigate the cause of several unexpected high amplitude oscillations that occurred in the surge tank water level of a real hydropower plant during secondary load-frequency control (LFC) maneuvers, after the replacement of the turbine runner, and to propose solutions that allow the power plant to continue providing secondary LFC in a safe and reliable manner....

Traditional cache replacement algorithms are not easily applicable to a dynamic and heterogeneous environment. Moreover, the frequently used hitratio and byte-hit ratio are not appropriate measures in grid applications, because non-uniformity of the resource object sizes and non-uniformity cost of cache misses in resource information traffic. In this paper, we propose a Least Frequently Cost ca...
