Bug severity is the degree of impact that a defect has on the development or operation of a component or system, and can be classified into different levels based on their impact on the system. Identification of severity level can be useful for bug triager in allocating the bug to the concerned bug fixer. Various researchers have attempted text mining techniques in predicting the severity of bu...

Anonymous CVS is an advanced source file distribution mechanism we created to allow open source software projects to distribute source code and information about code to Internet users. Built on top of the Concurrent Versions System (CVS) revision control system, Anonymous CVS safely allows anonymous read-only access to a CVS source repository. Prior to the introduction of Anonymous CVS, access...

Context: Although reliability is a major concern of most open source projects, research on this problem has attracted attention only recently. In addition, the optimal versiondating for open source software considering its special properties is not yet discussed. Objective: In this paper, the reliability analysis and optimal version-updating for open source software are studied. Method: A modif...

Rajaee port in Bandar Abbas is one of the important-oil transport hubs in Persian Gulf and any oil spill incidents can result in pollution, which impact on human habitats and the marine environment. Oil spill trajectory modeling is a tool which applied to increase the knowledge about oil spill fate. The GNOME model is a physical model which indicates the oil spill movements on sea water and pot...

In three experiments, participants named target pictures by means of German compound words (e.g., Gartenstuhl-garden chair), each accompanied by two different distractor pictures (e.g., lawn mower and swimming pool). Targets and distractor pictures were semantically related either associatively (garden chair and lawn mower) or by a shared semantic category (garden chair and wardrobe). Within ea...

Modern program analysis environments lack a principled method of monitoring low-level memory events. Such monitoring is of great value to activities like debugging, reverse engineering, vulnerability analysis, and security policy enforcement. Although current systems can be coerced to produce streams of memory events, most such techniques are inefficient or overly invasive and offer an unconstr...

Countries located on the Black Sea coast perform most of their sea trade through Istanbul Strait (IS). Approximately 50,000 ships pass IS each year, with crude oil tankers making up majority. Thus, aim study is to determine acute toxic effect pollution that may occur as a result tanker accidents in IS. By utilising data related have occurred IS, locations concentrated accidents, or “hot spots,”...

1935-1939 yılları arasında Polonya Tayyare Fabrikaları, Türkçeye daha tam çeviriyle “Devlet Havacılık Sanayi İmalathaneleri” [Państwowe Zakłady Lotnicze] PeZeLet’in gövdesi tamamen metalden yapılma avcı uçağı P-24, havacılık uzmanları tarafından dünyadaki en iyi uçakları sayılıyordu. Uçağın bu modeli martı kanatlı P-11’in yurt dışına ihraç edilmek üzere geliştirilmiş, üzerinde 900 HP’lik (662 k...

Traditional logic-based speci cation approaches x the structure and the dynamics of an object system at speci cation time. Information systems are applications with a very long life-time. Therefore, object and speci cation evolution to react on changing requirements is a relevant aspect of describing information systems as object societies. We present a logical speci cation framework for evolvi...

Laser-based missile-defence systems are being increasingly employed on aircraft to provide protection when attacked by optically-guided weapons. In some engagements the laser beam must pass through the exhaust gases of the aircraft. To predict the increase in laser beam divergence and jitter of the laser beam direction, an understanding of the exhaust gas structure and its influence is required...
