Monitoring unused or dark IP addresses offers opportunities to extract useful information about both on-going and new attack patterns. In recent years, different techniques have been used to analyze such traffic including sequential analysis where a change in traffic behavior, for example change in mean, is used as an indication of malicious activity. Change points themselves say little about d...

Urban traffic plans (UTPs) are tactical planning tools for managing urban areas and traffic noise abatement is one of their objectives, explicitly provided for under Italian law. To date, the various models and methods for estimating traffic noise have concerned its estimation in a point (or on a road segment). In this paper we propose a method that is able to evaluate the effects of UTPs on no...

To properly define countermeasures to improve traffic safety it is necessary to determine the specific causes and circumstances of accidents. In this sense, the current practice, developed a series of tools for the analysis of accidents that can accurately point to the problem. In-depth analysis of accidents or as they are called independent assessment of traffic accidents is one of the modern ...

We consider the fixed-cycle traffic-light (FCTL) queue, where vehicles arrive at an intersection controlled by a traffic light and form a queue. The traffic light signal alternates between green and red periods, and delayed vehicles are assumed to depart during the green period at equal time intervals. Most of the research done on the FCTL queue assumes that the vehicles arrive at the intersect...

The use of IP traffic prediction techniques for DAMA TDMA protocols is investigated in this paper. The predicted traffic distribution is derived when the input traffic shows long-range dependence features. Furthermore, an equivalent bandwidth is calculated, which allows the wireless terminal to request a certain amount of bandwidth (slot duration) in terms of a target traffic loss probability. ...

background: iran is one of the countries with considerable road traffic injuries.  pre-hospital interventions have an important role in preventing mortalities and disabilities caused by traffic accidents.the present study aimed to explore the barriers of pre-hospital care in traffic injuries in tehran, iran. methods: a qualitative content analysis approach was conducted based on 21 semi-structu...

There is an imperative need to understand how, where and when traffic accidents occur in order to develop appropriate accident reduction strategies. An improved understanding of the location, time and reasons for traffic accidents makes a significant contribution to preventing them. Traffic accident occurrences have been extensively studied from different spatial and temporal points of view usi...

Fast and accurate network traffic identification is becoming essential for network management, high quality of service control and early detection of network traffic abnormalities. Techniques based on statistical features of packet flows have recently become popular for network classification due to the limitations of traditional port and payload based methods. In this paper, we propose a metho...

background: traffic accidents are the main cause of death and disability in the world and iran. the injuries caused by traffic accidents may result in severe limitations and worst outcomes in various aspects of lives of traffic accident injured people and their families. therefore, understanding their experiences is very important to design better programs with regard to their treatment and ret...
