artificial neural networks (anns) are computer techniques that attempt to simulate the functionality and decision-making processes of the human brain. in the past few decades, artificial neural networks (anns) have been extensively used in a wide range of engineering applications. there are only a few applications in liquid membrane process. the objective of this research was to develop artific...

BACKGROUND An unknown input function can be determined by deconvolution using the systemic bolus input function (r) determined using an experimental input of duration ranging from a few seconds to many minutes. The quantitative relation between the duration of the input and the accuracy of r is unknown. Although a large number of deconvolution procedures have been described, these routines are ...

conclusions the distribution patterns of phase-variable genes in pakistani h. pylori strains were found to be somewhat different. the dominant prevalence of the hsdr gene was an interesting finding, considering its role in bacterial defense in both micro- and macroenvironments. results on culturing, the prevalence of h. pylori infections in the samples was 44.7%. the prevalence was higher in fe...

In many quantum key distribution (QKD) protocols, the receiver has to randomly change a measurement basis for each pulse or each train of pulses. This random change requires us to generate a huge amount of random numbers. It is also cumbersome for some QKD protocols, such as the round-robin differential phase shift QKD protocol, to change the basis rapidly. In this presentation, we address thes...

â  in order to determine the snowfall threshold temperature in different regions of kurdistan province, first the occurrence times of the non shower snow, associated with dry-bulb temperature and dew point temperature at the time of observation were extracted for 7 synoptic stations of the province. then, the frequency, relative frequency and cumulative frequency of snowfall in different temper...

It has been argued that pension funds should have limitations on their asset allocation, based on the risk profile of the different financial instruments available on the financial markets. This issue proves to be highly relevant at times of market crisis, when a regulation establishing limits to risk taking for pension funds could prevent defaults. In this paper we present a framework for eval...

The connection between the instantaneous frequency and the angle derivative of the fractional power spectra is established. It permits to solve the signal retrieval problem if only two close fractional power spectra are known. This fact is used in the reconstruction of the Wigner distribution or the pseudo Wigner distribution from two close projections. Keywords—Wigner distribution, fractional ...

Round-Robin Differential Phase-Shift (RRDPS) is a Quantum Key Distribution (QKD) scheme proposed by Sasaki, Yamamoto and Koashi in 2014 [1]. It works with highdimensional quantum digits (qudits). Its main advantage is that it tolerates more noise than qubit-based schemes while being easy to implement. The security of RRDPS has been discussed in several papers [1, 2, 3]. However, these analyses ...

Functional principal component analysis (FPCA) based on Karhunen–Loève (K–L) expansion allows to describe the stochastic evolution of main characteristics associated multiple systems and devices. Identifying probability distribution scores is fundamental characterize whole process. The aim this work consider a family statistical distributions that could be accurately adjusted previous transform...
