A number of studies have shown that stationary backgrounds compromise smooth pursuit eye movements. It has been suggested that poor attentional selection of the pursuit target was responsible for reductions of pursuit gain. To quantify the detrimental effects of attention, we instructed observers to either pay attention to background objects or to ignore them. The to-be-attended object was indi...

Abstract Fixed-energy quantum inversion method is applied to determine model independent $$\alpha $$ α -particle scattering potentials within the energy range between 0 and 50 MeV. Only experimentally allowed even phase shifts are used in calculation. Detailed results exhibited at low higher energies show up ...

We analyze the performance of the Maastricht convergence criteria (inflation, long-term interest rate, annual and overall public debt) of the European Monetary Union (EMU) that led to the introduction of the Euro on Jan. 1 1999 as book currency. Defining 3 regimes, 1992-97, 1997-1999 and 2000-2001, we analyse convergence properties, like a smooth or a rough transition in the mean or variance sh...

Environmental crisis and shortage of fossil fuels make Electric Vehicles (EVs) alternatives for conventional vehicles. With growing numbers of EVs, the coordinated charging is necessary to prevent problems such as large peaks and power losses for grid and to minimize charging costs of EVs for EV owners. Therefore, this paper proposes an optimal charging schedule based on Dynamic Programming (DP...

nowadays nmr spectroscopy becomes a powerful tool in chemistry because of the nmr chemical shifts. hartree–fock theory and the gauge-including atomic orbital (giao) methods are used in the calculation of 29si nmr chemical shifts of various silicate species in the silicate solution as initial components for zeolite synthesis both in gas and solution phase. calculations have been performed at geo...

The 13C chemical shifts for a series of compounds which includes carboxylic acids, aldehydes, ethers, ketones and hydrocarbons were simulated by using the parametric techniques. The observed chemical shifts were related to numerically encoded structural parametes called descriptors. Two new electronic descriptors were added to the previous descriptors. Ploting of experimental ver...

in this paper we present a method for optimal design of combined ewma-ewma control scheme. shewhart control chart, introduced by walter shewhart, only takes into account present information of the process, so it is insensitive in detecting small shifts. ewma and cusum control charts are good choices for detecting small shifts. a combined control scheme monitors the process for large and small s...

Strong positive feedback is considered a necessary condition to observe abrupt shifts of ecosystems. A few previous studies have shown that demographic noise -- arising from the probabilistic and discrete nature birth death processes in finite systems makes transitions gradual or continuous. In this paper, we show may, fact, promote would otherwise continuous transitions. We present our methods...
