The first sequencing of a complete genome was published forty years ago by the double Nobel Prize in Chemistry winner Frederick Sanger. That corresponded to the small sized genome of a bacteriophage, but since then there have been many complex organisms whose DNA have been sequenced. This was possible thanks to continuous advances in the fields of(More)
Web applications development using various technologies has become a standard procedure for shops and businesses. These web applications require distribution systems of web requests that allow and support the dynamism of these environments, to provide service availability and resource use, commonly heterogeneous.
In this paper we propose a new protocol to manage multicast key distribution. The protocol is based on the use of orthogonal systems in vector spaces. The main advantage in comparison to other existing multicast key management protocols is that the length and the number of the messages which have to be sent are considerably smaller. This makes the protocol(More)
Prevention and detection of bullying due to racial stigma was studied in school contexts using a system designed following "gamification" principles and integrating less usual elements, such as social interaction, augmented reality and cell phones in educational scenarios. "Grounded Theory" and "User Centered Design" were employed to explore coexistence(More)
In this paper we use the Diffie–Hellman key exchange protocol to introduce a decentralized key agreement protocol based on elliptic curves. We do not use any public key infrastructure, which makes it suitable for light devices with low computational and storage capabilities. Thus mobile devices can directly authorize other mobile devices to exchange keys in(More)

Corporations invest amounts of capital in building plans to organize their workers. Academic institutions, especially in Europe, is moving towards the student so a much more coordination is required for both teachers and students. There are pretty much methodologies to organize how task should be accomplished but they lack effectiveness due to a poor(More)
