In this paper two criteria for evaluation of power balance control performance in control areas of the UCTE interconnection are proposed: the mean value of Area Control Error (ACE) and the standard deviation of ACE. A methodology for assigning fair values of the two criteria to individual control areas is presented. This methodology ensures that the UCTE grid is operated in a safe manner and no...

The problem of consensus reaching in the group decision making situations is considered. Assuming a heterogeneous and linguistic group decision making context various linguistic consensus measures are presented to guide the consensus process. Considering linguistic preference relations to provide experts' opinions, they are deened in three levels of action: level of the pairs alternatives, leve...

In a number of recent experimental studies it has been reported that synaptic transmission is activity-dependent process. In this paper we study whether and how the synaptic plasticity, in particular, short-term depression a!ects coincidence detection. We explore the responses of a neuron to massive input of Poisson distributed spike trains containing a signal of coincident presynaptic spikes. ...

We prove that there is a coincidence index for the inclusion F (x) ∈ Φ(x) when Φ is convex-valued and satisfies certain compactness assumptions on countable sets. For F we assume only that it provides a coincidence index for single-valued finite-dimensional maps (e.g. F is a Vietoris map). For the special case F = id, the obtained fixed point index is defined if Φ is countably condensing; the a...

We study the interference pattern of biphotons passing through a dispersive medium, and devise a method for measuring dispersion in coincidence counting of entangled photons. By measuring the Gouy phase shift accompanying dispersion, we show that it fundamentally differs from the Gouy phase expected from classical models. Finally, we show that the second-order correlation function of the disper...

for analyzing the issue of coincidence of immanence with transcendence in whitehead’s process philosophy, the present paper attempts at the beginning to show that in this process system, especially in the framework of inclusive and comprehensive categories, entities should be interweave and have organic interrelation; because all the actual entities have reaction against each other. so the prer...

pet (positron emission tomography) is a powerful imaging technique that can provide quantitative information on the distribution of positron emitter labeled radiopharmaceuticals (pet radiopharmaceuticals) in the body. positrons (ß+) are positively charged beta particles. they are emitted when the atom is proton rich. a positron has only a transient existence. after losing all of its kinetic ene...

We consider the coincidence problem for the square lattice that is translated by an arbitrary vector. General results are obtained about the set of coincidence isometries and the coincidence site lattices of a shifted square lattice by identifying the square lattice with the ring of Gaussian integers. To illustrate them, we calculate the set of coincidence isometries, as well as generating func...

delay lines gating neurons Jeffress (1948) model of auditory localization. (a) Elementary delay line and coincidence counting neuron. (b) Array of coincidence counters organized tonotopically and by interaural delay (correlation lag). (c) Pattern evoked by a wideband sound source displaced from the axis. A ridge occurs at the internal delay that compensates for the external interaural delay of ...

A common coincidence point theorem for R-weakly commuting mappings is obtained. Our result extend several ones existing in literature. 2000 Mathematics Subject Classification. 54H25.
