aims: it is very important to detect the coagulase-negative staphylococci, which produce the hospital infections. being one of the most expensive and time-consuming stages before the polymerase chain reaction (pcr), dna extraction is one of the primary stages of pcr. then, it should be noticed that the elimination of the stage might save time and costs. the aim of this study was to compare two ...

abstract—today, botnets have become a serious threat to enterprise networks. by creation of network of bots, they launch several attacks, distributed denial of service attacks (ddos) on networks is a sample of such attacks. such attacks with the occupation of system resources, have proven to be an effective method of denying network services. botnets that launch http packet flood attacks agains...

For the past few months the Ulster Medical Society has had a presence on the worldwide web. It was not launched with any ceremony and so far it is not listed by a Google search but it is there. The site has been kept simple to ease construction and the pages have been kept small to reduce loading times. Only 50% of web surfers will wait more than 8 seconds for a page to download and while we wo...

The HTTP=1.1 protocol is the result of four years of discussion and debate among a broad group of Web researchers and developers. It improves upon its phenomenally successful predecessor, HTTP=1.0, in numerous ways. We discuss the differences between HTTP=1.0 and HTTP=1.1, as well as some of the rationale behind these changes.  1999 Published by Elsevier Science B.V. All rights reserved.

With the standardization of HTTP/2, content providers want to understand the benefits and pitfalls of transitioning to the new standard. Using a large dataset of HTTP/1.1 resource timing data from production traffic on Akamai’s CDN, and a model of HTTP/2 behavior, we obtain the distribution of performance differences between the protocol versions for nearly 280,000 downloads. We find that HTTP/...

Abstract— Bot networks are a serious threat to cyber security, whose destructive behavior affects network performance directly. Detecting of infected HTTP communications is a big challenge because infected HTTP connections are clearly merged with other types of HTTP traffic. Cybercriminals prefer to use the web as a communication environment to launch application layer attacks and secretly enga...
