Human retina consists of repeating pattern of arteries and veins. This repeating pattern is known as Fractals. Fractal Dimension is the quantity which is to be determined for analyzing disorder in retina using fractal analysis. There are two disorders of retina which leads to complete vision loss. They are Occlusion and Diabetic Retinopathy. Occlusion is due to arteries crossing over vein leadi...
Introduction Stripped to its essence, the highest requirement of any election is that it produces an accurate published count of the eligible voters’ intended choices – that is, it must be “counted-as-intended.” Typically, this process is divided into two stages: casting and counting. To maintain the electorate’s belief and willingness to be bound by the outcome of an election, both voters and ...
We recently presented a method of analyzing invariant-mass spectra of kaon pairs resulting from decay of φ mesons produced in high-energy heavy-ion collisions. It can be used to extract the shifts in the mass and the width (∆M and ∆Γ) of the φ mesons when they are inside the dense matter formed in these collisions. We have now performed a Monte-Carlo simulation of this process. We illustrate ou...
With the introduction of the Schrödinger equation in 1926, it was in principle clear how to describe a molecular system and its properties exactly in a nonrelativistic sense. However, for most molecular systems of chemical interest, the analytic solution of the Schrödinger equation is not possible. Therefore, since 1926, a multitude of hierarchical approximations (some of which are displayed in...
Various methods have been developed for detecting functional couplings among proteins. These include recently developed computational techniques such as the protein phylogenetic profile method [1] and the Rosetta Stone method [2], as well as experimental techniques such as mRNA expression profiling [5]. Here, we present a general approach for quantitatively discriminating more informative funct...
The communication between a developer and a domain expert (or manager) is very important for successful deployment of formal methods. On the one hand it is crucial for the developer to get feedback from the domain expert for further development. On the other hand the domain expert needs to check whether his expectations are met. An animation tool allows to check the presence of desired function...
This work presents a new Visual Basic 6.0 application for estimating the fractal dimension of images, based on an optimized version of the box-counting algorithm. Following the attempt to separate the real information from “noise”, we considered also the family of all band-pass filters with the same band-width (specified as parameter). The fractal dimension can be thus represented as a function...
Multifractal box counting analysis has been widely applied to study the scaling characteristics of grayscale images. Since bit depth is an important property of such images it is desirable know the impact of varying bit depths on the estimation of the generalized dimensions (Dq). We generated random geometrical multifractal grayscale fields, which were then transformed from double precision to ...
Alzheimer’s disease (AD) is the common neurodegenerative and irreversible disease in the population. Early detection and treatment to this disease will control the disease progression. Mostly classification of this disease is performed manually in the clinical studies. It is time consuming as well as manual classification is difficult and it is purely based on clinician’s ability. Multimodality...
