The Omega polynomial(x) was recently proposed by Diudea, based on the length of strips in given graph G. The Sadhana polynomial has been defined to evaluate the Sadhana index of a molecular graph. The PI polynomial is another molecular descriptor. In this paper we compute these three polynomials for some infinite classes of nanostructures.

telemedicine has changed the way of health care. it is an indispensable tool in the hands of doctors to accelerate and facilitate the process of data interchange. wireless networks consist of small nodes with communications capabilities. development of wireless networks of telemedicine system is highly demanded since these networks promise a wide range of potential applications. in this paper t...

The aim of this study is to demonstrate the feasibility of estimating the strength of the moving radiation source during patient implantation. The requirement for the counting time was investigated by comparing the results of the measurements for the static source with those for the source moving at 2, 5, 10 and 20 cm s(-1). The utilized source was (125)I with an air-kerma strength of 0.432 U (...

Let G = (U; V; E) be a bipartite graph with jUj = jV j = n. The factor size of G, f, is the maximum number of edge disjoint perfect matchings in G. We characterize the complexity of counting the number of perfect match-ings in classes of graphs parameterized by factor size. We describe the simple algorithm, which is an approximation algorithm for the permanent that is a natural simpliication of...

Background Traditionally, the identification of cognitive impairment is based on neuropsychological tests and supported with not widely available biomarkers. This study aimed to establish association between motor function (Gait Speed Handgrip Strength) performance in a global various domains. Our secondary objective was determine cut-off point for Gait Strength classify older adults as cogniti...

We discuss quantum algorithms that calculate numerical integrals and descriptive statistics of stochastic processes. With either of two distinct a p proaches, one obtains an exponential speed increase in comparison to the fastest known classical deterministic algorithms and a quadratic speed increase in comparison to classical Monte Carlo (probabilistic) methods. We derive a simpler and slightl...

Video based vehicle detection technology is an integral part of Intelligent Transportation System (ITS), due to its non-intrusiveness & comprehensive vehicle behavior data collection capabilities. Digital Image processing has been applied to traffic analysis in recent years, with different goals. In recent years, image processing has been applied to field of traffic research with goals that inc...
