Nowadays every network is susceptible on a daily basis to a significant number of different threats and attacks both from the inside and outside world. Some attacks only exploit system vulnerabilities and their traffic pattern is undistinguishable from normal behavior, but in many cases the attack mechanisms combine protocol or OS tampering activity with a specific traffic pattern having its ow...

conclusions our findings reveal that there are temporal variations in traffic accidents, and long holidays significantly influence accident rates. traffic injuries have different patterns on outer/inner city roads, based on weekday and holiday status. thus, these findings could be used to create effective initiatives aimed at traffic management. materials and methods all road traffic accidents ...

Experiments using real traffic traces are of key importance in many network management research fields, such as traffic characterization, intrusion detection, and accounting. Access to such traces is often restricted due to privacy issues; research institutions typically have to sign non-disclosure agreements before accessing such traces from a network operator. Having such restrictions, resear...

In this paper, some issues in scheduling multimedia traffic over the HSDPA link of UMTS are addressed. Unlike previous contributions, the focus is on the case where packets having different QoS attributes need to be delivered to a specific user as part of a multimedia application packet delivery process. The following packet scheduling algorithms were considered: Max C/I, Proportional Fair (PF)...

BACKGROUND Previous research suggests that children born prematurely or with a low birth weight are more vulnerable to the mental health effects of ambient neighbourhood noise; predominantly road and rail noise, at home. This study used data from the Road Traffic and Aircraft Noise Exposure and Children's Cognition and Health (RANCH) study to see if this finding extends to aircraft and road tra...

This study was carried out to analyze the variations of Benzene, Toluene, and para- Xylene (BTp-X) present in the urban air of Delhi. These pollutants can enter into the human body through various pathways like inhalation, oral and dermal exposure posing adverse effects on human health. Keeping in view of the above facts, six different locations of Delhi were selected for the study during summe...

conclusions better understanding of the effectiveness and efficiency mechanism and having valid evaluation required considering specific theories and points in this field. applying a dynamic approach with considering epidemiological concepts and sophisticated statistical models could improve quality of studies in this field. results from a total of 797 articles, 20 were eligible which among the...

conclusions willingness to pay can be affected by experiencing an accident, the distance of the daily trip, and helmet use. the cost of traffic injuries among motorcyclists shows that this rate is much higher than the global average. thus, expenditure should be made on effective initiatives such as the safety of motorcyclists. results the mean wtp was 888,110 irr (iranian rial) among motorcycli...

The primary weakness of the paper is having only a single day of sampling. The potential for a single day to have unusual meteorological or traffic characteristics is high, and without more details and more analysis of how representative this day was of typical, I feel it is incomplete and not ready for publishing. This is unfortunate because it seems to be a well-conducted study. Are more days...
