This paper describes a pattern-based approach to building packet classifiers. One novelty of the approach is that it can be implemented efficiently in both software and hardware. A performance study shows that the software implementation is about twice as fast as existing mechanisms, and that the hardware implementation is currently able to keep up with OC-12 (622Mbps) network links and is like...

The Fukushima Daiichi nuclear power plant accident in Japan triggered by a magnitude 9.0 earthquake and resulting tsunami on March 11, 2011 caused the month-long discharge of radioactive materials into the atmosphere. It is urgent to assess the radiological dose to the public resulting from this release, using both environmental monitoring data and computer simulation based on atmospheric dispe...

To minimize industrial accidents, it's critical to evaluate a firm's priorities for prevention factors and strategies since such evaluation provides decisive information for preventing industrial accidents and maintaining safety management. Therefore, this paper proposes the evaluation of priorities through statistical testing of prevention factors with a cause analysis in a cause and effect mo...

A better understanding of the risk involved in riding different sizes and types of motor vehicles is required to make informed decisions regarding a reasonable level of protection for wheelchair riders. Wheelchair rider accident information that can be used to estimate risk is quite limited. This paper reviewed the resources available, including the National Electronic Injury Surveillance Syste...

DESIGN Analysis of national databases for cost of illness. SETTING United Kingdom, 1999, cost to the National Health Service (NHS) and Personal Social Services (PSS). PARTICIPANTS Four age groups of people ...

We conducted a systematic review and meta-analysis of prospective cohort studies of subjects with acute whiplash injuries. The aim was to describe the course of recovery, pain and disability symptoms and also to assess the influence of different prognostic factors on outcome. Studies were selected for inclusion if they enrolled subjects with neck pain within six weeks of a car accident and meas...

One of the major health consequences of the Chernobyl Nuclear Power Plant accident in 1986 was a dramatic increase in incidence of thyroid cancer among those who were aged less than 18 years at the time of the accident. This increase has been directly linked in several analytic epidemiological studies to iodine-131 (131I) thyroid doses received from the accident. However, there remains limited ...

In 2002 the Department for Transport (Df T) added a requirement to the 2010 casualty reduction target to tackle the significantly higher incidence in disadvantaged communities. In October 2002, the Government launched the £17 million Neighbourhood Road Safety Initiative (NRSI). Fifteen local authorities, mainly in the north of England, with high casualty rates and levels of deprivation were inv...
