The link between these malformations and defective erythropoiesis is unclear: a defect in a molecule acting both on embryo development and haemopoiesis has been proposed. Inheritance is autosomal(More)
This paper presents CiVedi, a scalable system providing a flexible and customizable virtual environment for displaying multimedia contents. Using CiVeDi, both the final users and the exhibition curators can personalize the content of the visit as well as the visit appearance and its duration. The proposed solution aims to be used transparently over(More)
In this paper we present the results from an analysis focusing on security threats that can arise against an SQL server when included in Web application environments. The approach used is based on the STRIDE classification methodology. The results presented provide also some general guidelines and countermeasures against the different attacks that can(More)
In the Internet of Things (IoT) era, we need to face increased masses of cross-domain data stored in different formats (either relational, XML, JSON, textual) and data streams (produced by sensors), that can be highly or loosely structured and need to be integrated for analysis. Recently, many NoSQL systems (e.g., MongoDB, Cassandra, HBASE) have been born(More)
