Supporting learning activities in virtual worlds: methods, tools and evaluation
(2013-02-27)
Continuing advances and reduced costs in computational power, graphics and network bandwidth let 3D immersive multi‐user Virtual Worlds (VWs) become increasingly accessible while offering an improved and engaging quality ...
Sequence analysis in bioinformatics: methodological and practical aspects
(2013-04-02)
My PhD research activities has focused on the development of new
computational methods for biological sequence analyses.
To overcome an intrinsic problem to protein sequence analysis, whose aim was
to infer homologies in ...
Secure computation under network and physical attacks
(2013-04-22)
This thesis proposes several protocols for achieving secure com-
putation under concurrent and physical attacks. Secure computation
allows many parties to compute a joint function of their inputs, while
keeping the privacy ...

La progressiva diffusione dei social network, sia generalisti (quali Twitter, Facebook o Google+, la recente piattaforma messa a punto da Google) sia specializzati (ad esempio le comunità professionali di Linkedin), ha ...
Memetic algorithms for ontology alignment
(2013-04-24)
Semantic interoperability represents the capability of two or more systems to
meaningfully and accurately interpret the exchanged data so as to produce
useful results. It is an essential feature of all distributed and open ...
On the Generalizations of Identity-Based Encryption
(2013-04-16)
Today public-key cryptographic is widely deployed and successfully used but still a major drawback
exists. In fact, from encrypted data a party can either decrypt or cannot learn anything at all about the
message other ...
Steganographic methods for information hiding in MS-Office files
(2013-04-20)
The simplest container of digital information is “the file" and among the vast array of files currently available, MS-Office files are probably the most widely used. These files, starting from MS-Office 2007, respect the ...
Hybrid approaches based on computational intelligence and semantic web for distributed situation and context awareness
(2013-04-29)
The research work focuses on Situation Awareness and Context Awareness topics.
Specifically, Situation Awareness involves being aware of what is happening in the vicinity
to understand how information, events, and one’s ...
