faults in computer networks may result in millions of dollars in cost. faults in a network need to be localized and repaired to keep the health of the network. fault management systems are used to keep today’s complex networks running without significant cost, either by using active techniques or passive techniques. in this paper, we propose a novel approach based on imperialist competitive alg...

systems of computers and their application in the lives of modern human beings are vastly expanding. in any kind of computer application, failure in computer systems can lead to a range of financial and mortal losses. indeed, the major origin of software failure can be located in designing or implementing software. with regard to these statistics, 30% of the software projects have been prospero...

background: routine repeat testing of critical laboratory values is very common these days to increase their accuracy and to avoid reporting false or infeasible results. we figure that repeat testing of critical laboratory values has any benefits or not.   methods : we examined 2233 repeated critical laboratory values in 13 different hematology and chemistry tests including: hemoglobin, white b...

Background: Epidemiological studies are shown robust association between human papillomavirus (HPV) and cervical cancer. From 1990 HPV was known as a necessary but insufficient cause of cervical invasive cancer. The purpose of this study was to evaluate the cost effectiveness of HPV test in cervical cancer screening. Materials and Methods: This is a systematic review article; the newest scienti...

In this paper, we propose a method for extracting an object region from an image. First, we investigate the properties of the Intelligent Scissors (IS) method, which has been proposed as a method for extracting contours. As a result, we verify that the IS method’s route search according to total cost requires multiple seed points to extract a complex contour. Next, we show that this problem can...

Our project work includes the embedding of a normalized cuts algorithm and testing its application for image segmentation. Proposed solution minimizes a graph bi partitioning based on a modified cost function. Final result has a form of partition candidates based on a low-level image description. To increase the stability of the proposed method, algorithm has an iterative form. Computational co...

In this paper, we introduce the novel parameters indicating Normalized Tenacity ($T_N$) and Normalized Toughness ($t_N$) by a modification on existing Tenacity and Toughness parameters.  Using these new parameters enables the graphs with different orders be comparable with each other regarding their vulnerabilities. These parameters are reviewed and discussed for some special graphs as well.
