Application-layer overlay networks have been proposed as an alternative method to overcome IP-layer path anomalies and provide users with improved routing services. Running at the application layer, overlay networks usually rely on probing mechanisms for IP-path performance monitoring and failure detection. Their service performance is jointly determined by their topology, parameters of probing...

Pavement systems have significant impacts on the environment and economy due to large material consumption, energy input, and capital investment. To evaluate the sustainability of rigid pavement overlay designs, an integrated life cycle assessment and life cycle cost analysis model was developed to calculate the environmental impacts and costs of overlay systems resulting from material producti...

Lately, peer-to-peer overlay networks and their ability to reflect the underlying network topology have been a focus in research. The main objective has been to reduce routing path lengths, stretched by the overlay routing process. In most solutions developed, a kind of fixed infrastructure in the form of so called landmarks or excessive message exchange are necessary to guarantee good overlay ...

It is a widely accepted notion that the native layer of the current Internet has begun to stagnate in terms of the services offered. Consequently, overlay networks have gained attention as a viable alternative to overcome functionality limitations of the Internet. A common approach to overlay network design holds the native network inviolable, implying that the overlay has to take on all the ta...

Byzantine faults in a peer-to-peer (P2P) system are resulted from adversarial and inconsistent peer behaviors. Malicious peers can disrupt the routing functions in peer joining and lookup services. Byzantine attackers may collude with each other to paralyze the entire P2P network operations. We discover a new class of DHT-based overlay networks, called inverse de Bruijn (IDB) graph, to enable m...

Due to the overwhelming amount of information on the Internet, it is becoming increasingly difficult for people to find relevant information in a timely fashion. Information filtering and dissemination systems allow user to register persistent queries called user profiles. They detect new contents, match them against the profiles, and continuously notify users when relevant information becomes ...

background institut pasteur international network (ipin), which includes 32 research institutes around the world, is a network of research and expertise to fight against infectious diseases. a scientometric approach was applied to describe research and collaboration activities of ipin.   methods publications were identified using a manual search of ipin member addresses in science citation inde...

As the web evolves, it is becoming easier to form communities based on shared interests, and to create, publish, and query data on a wide variety of topics. In order to fully deliver on the promise of free data exchange, any community-supporting infrastructure needs to enforce the key requirement to preserve privacy of the association of content providers with potential sensitive published info...

Reflective cracking is a common distress of semi-rigid base asphalt pavements and overlay pavement projects. An rubber stress-absorbing membrane interlayer (AR-SAMI) prepared by waste tires an effective engineering solution for treating reflective cracking. This method can also reduce black pollution. However, there no unified test index crack resistance evaluation. In this work, AR-SAMIs with ...

The research community has turned to create Semantic Overlay Networks for information retrieval in large scale peer-to-peer networks. Much research work in semantic overlay protocols and searching algorithms is done and their results indicate that semantic overlay is powerful for content searching in peer-to-peer network. However, very limited work has been done in analyzing and evaluating char...
