The application of logarithmic transformations to speckle images is sometimes desirable in converting the speckle noise distribution into an additive, constant-variance noise distribution. The optical transmission properties of some bacteriorhodopsin films are well suited to implement such a transformation optically in a parallel fashion. I present experimental results of the optical conversion...

BACKGROUND In most biological experiments, especially infectious disease, the exposure-response relationship is interrelated by a multitude of factors rather than many independent factors. Little is known about the suitability of ordinary, categorical exposures, and logarithmic transformation which have been presented in logistic regression models to assess the likelihood of an infectious disea...

In this paper we analyze the convergence and stability of the iterated Lubkin transformation and the θ-algorithm as these are being applied to sequences {An} whose members behave like An ∼ A+ ζn/(n!)r ∑∞ i=0 αin γ−i as n → ∞, where ζ and γ are complex scalars and r is a nonnegative integer. We study the three different cases in which (i) r = 0, ζ = 1, and γ 6= 0, 1, . . . (logarithmic sequences...

Ultrasound imaging is an incontestable vital tool for diagnosis, it provides in non-invasive manner the internal structure of the body to detect eventually diseases or abnormalities tissues. Unfortunately, the presence of speckle noise in these images affects edges and fine details which limit the contrast resolution and make diagnostic more difficult. In this paper, we propose a denoising appr...

Estimation of genetic trends is necessary to monitor and evaluate selection programs. The objective of this study was to estimate the genetic trends for milk yield in Iranian Holsteins cows using random regression test day model. Data set was consisted of 743205 test-day records from 1991 to 2008, which were collected by the Animal Breeding Centre of Iran. Breeding, environmental and phenotypic...

This paper studies the stability of a network flow model with transmission and queuing delays in the forward and backward channels. We present a novel small gain approach to prove global asymptotic stability for arbitrary time delays and network routing. This approach uses a logarithmic state transformation suggested recently in the literature, and establishes a linear input-to-state gain for t...

In the article, we propose a new estimator of the hazard rate function in the framework of the multiplicative point process intensity model. The technique combines the reflection method and the method of transformation. The new method eliminates the boundary effect for suitably selected transformations reducing the bias at the boundary and keeping the asymptotics of the variance. The transforma...
