Using a function algebra characterization of exponential time due to Monien 5], in the style of Bellantoni-Cook 2], we characterize exponential time functions of linear growth via a safe course-of-values recursion scheme.

This paper presents an analysis-by-synthesis technique to evaluate the perceptual importance of multimedia packets for ratedistortion optimized streaming. The proposed technique, instead of relying on a priori information, computes the distortion that would be caused by the loss of each single packet, including the effects of error propagation and receiver-side error concealment. A rate-distort...

Many connectionist learning models are implemented using a gradient descent in a least squares error function of the output and teacher signal. The present model Fneralizes. in particular. back-propagation [1] by using Minkowski-r power metrics. For small r's a "city-block" error metric is approximated and for large r's the "maximum" or "supremum" metric is approached. while for r=2 the standar...

in this paper, we proposed an algorithm for solving the problem of task scheduling using particle swarm optimization algorithm, with changes in the selection and removing the guide and also using the technique to get away from the bad, to move away from local extreme and diversity. scheduling algorithms play an important role in grid computing, parallel tasks scheduling and sending them to appr...

in this work, the adsorption of carbon dioxide from model flue gas on different adsorbents has been investigated. using simplified modeling, parameters such as the total mass transfer coefficient and the effective diffusivity have been determined. experiments were carried out in two sections: firstly, adsorption of pure carbon dioxide on different adsorbents was measured at pressures ranging fr...

This article is a critical review of some of the methods that have been used for the sampling, analysis, and monitoring of vapor-phase toluene diisocyanate (TDI). Only some of the methods that have received relatively widespread application have been addressed in this article. This review includes a "tutorial style" discussion of basic definitions and basic principles and procedures of quality ...

Figure 2. Regional ADC and FA values at 2 hour and 4 hour after TBI for hippocampus ipsilateral (hip_ips) and contralateral (hip_con) , thalamus ipsilateral (tha_ips) and contralateral (tha_con), olfactory ipsilateral (of_ips) and contralateral (of_con). Error bar shows standard error (= standard deviation/√sample size). ( * is for significance level of p < 0.05. # is for significance level of ...
