The Distributed Denial of Service (DDoS) attack is a serious cyber security that attempts to disrupt the availability principle computer networks and information systems. It's critical detect DDoS attacks quickly accurately while using as less computing power possible in order minimize damage cost efficient. This research proposes fast high-accuracy detection approach by features selected propo...

BACKGROUND In order to help assess resident performance during training, the Residency Affair Committee of the Pediatric Residency Program of the University of Padua (Italy) administered a Resident Assessment Questionnaire (ReAQ), which both residents and faculty were asked to complete. The aim of this article is to present the ReAQ and its validation. METHODS The ReAQ consists of 20 items th...

The development of methods to deal with the informative contents of the text units in the matching process is a major challenge in automatic summary evaluation systems that use fixed n-gram matching. The limitation causes inaccurate matching between units in a peer and reference summaries. The present study introduces a new Keyphrase based Summary Evaluator (KpEval) for evaluating automatic sum...

Two measures of association for dichotomous variables, the phi-coefficient and the tetrachoric correlation coefficient, are reviewed and differences between the two are discussed in the context of the famous so-called Pearson-Yule debate, that took place in the early 20th century. The two measures of association are given mathematically rigorous definitions, their underlying assumptions are for...

CONTEXT Increased 5-year survival for cancer patients is generally inferred to mean that cancer treatment has improved and that fewer patients die of cancer. Increased 5-year survival, however, may also reflect changes in diagnosis: finding more people with early-stage cancer, including some who would never have become symptomatic from their cancer. OBJECTIVE To determine the relationship ove...

Elements in a sample date are demonstrated based on their characteristics and in turn the characteristics are represented by variables. Identifying the relationship between these variables is crucial for prediction, hypothesis testing, and decision making. The relation between two variables is often quantified using a correlation factor. Once correlation is known it can be used to make predicti...
