Distributed directory protocols for shared objects play an important role in providing access to higher level abstractions like transactional memory. They offer primitives to retrieve data and read it, or to move data and allow to write it. This chapter describes directory protocols for large-scale distributed systems and discusses the subtleties of incorporating them in a large-scale distribut...

In this paper, we present a method for correcting a skeleton-based vectorization. The method robustly segments the skeleton of an image into basic features, and uses these features to reconstruct analytically all the junctions. It corrects some of the topological errors usually brought by polygonal approximation methods, and improves the precision of the junction points detection. We rst give s...

Machines that provide TCP services are often susceptible to various types of Denial of Service attacks from external hosts on the network. One particular type of attack is known as a SYN flood, where external hosts attempt to overwhelm the server machine by sending a constant stream of TCP connection requests, forcing the server to allocate resources for each new connection until all resources ...

A survey was conducted on the use of ICT by visually impaired people. Among 304 respondents, 81 used smartphones and 44, tablets. Blind people used feature phones at a higher rate and smartphones and tablets at lower rates than people with low vision. The most popular smartphone model was iPhone and the most popular tablet model was iPad. While almost all blind users used the speech output acce...

In early stages of experimentation, one often has many candidate factors of which only few have signiŽ cant in uence on the response. Supersaturated designs can offer important advantages. However, standard regression techniques of Ž tting a prediction line using all candidate variables fail to analyze data from such designs. Stepwise regression may be used but has drawbacks as reported in the...

According to the different analysis methods, the intrusion detection is divided into anomaly detection and misuse detection. In this thesis, we analyze the advantages and drawbacks of detection technology, Due to that, this paper proposes a IDS model based on multi-technique with misuse detection and anomaly detection which can overcome their drawbacks and develop their advantages to detect the...

A literature review of tile treatment of cartilage defects was conducted, examining the current literature on the well-known treatments. In particular, advantages and drawbacks of each of the discussed treatments were evaluated considering outcomes available in literature. The literature search was conducted on PubMed and Scopus using appropriate keywords in relation to cartilage defects. Main ...
