background and objectives:hbv and htlv-i are life threatening infectious agents in patients who receive blood and blood products. although serological methods have been proved to be useful, detection of these viruses has remained a challengingissue due to the many obstacles. by the advent of nucleic acid testing methods, especially in multiplex format, more precise detection is possible.the obj...

This paper presents the results of a survey on cluster of rice industries that investigates the effect of voltage sag on the industries feeding from same source. The survey also observed factory operation, products, equipment and processes used in production. In this paper we analyzed an electrical system sensitivity regarding voltage sags. Several proposals are there to analyzing the sensitivi...

Today lymphomas are defined according to a combination of morphology, immunophenotype, genetic features and clinical presentation, so beside the pure cytomorphologic analysis in diagnosis of lymphoma ancillary techniques such as cytochemistry, immunocytochemistry, molecular diagnosis and flow cytometry (FC) are often used. Our goal was to determinate how is information given by fine-needle aspi...

When analyzing neuron spike trains, it is always the problem of how to set the time bin. Bin width affects much to analyzed results of such as periodicity of the spike trains. Many approaches have been proposed to determine the bin setting. However, these bins are fixed through the analysis. In this paper, we propose a randomizing method of bin width and location instead of conventional fixed b...

Applications of machine learning have shown repeatedly that the standard assumptions of uniform class distribution and uniform misclassification costs rarely hold. Little is known about how to select classifiers when error costs and class distributions are not known precisely at training time, or when they can change. We present a method for analyzing and visualizing the performance of classifi...

This paper describes a technique for analyzing the stochastic structure of the vectorial capacity using moment–generating functions. In such formulation, for an infectious disease transmitted by a vector, we obtain the generating function for the distribution of the number of infectious contacts (e.g., infectious bites from mosquitoes) between vectors and humans after a contact to a single infe...
