We demonstrate that the typical problem of loss in performance due
to disk I/O can be efficiently dealt with by using separate strategies
for the storage of file data and data structures required for file
management. Furthermore, to make the design very reliable, stable
storage is provided. In fact the design is reliable to the extent that
even aft...

In this article we propose a peer to peer system able to permit a collaborative information exchange between public administrations. The system acts as a peer to peer network for document retrieval but in every single peer of network there is a search engine capable to index documents and able to share index information with other members
Access to real-time data while in field observations is often a requested issue in environmental management. Additionally, it is easier to see that information spatially distributed where it makes sense, leveraging users of the task of searching for the context where the retrieved information can be applied. Augmented Reality (AR) is a technology t...
When interacting with natural or urban environments there are many situations where the ability to access data in real time becomes relevant. Augmented Reality (AR) technologies allow real time superimposition of synthetic objects on real images, providing an augmented knowledge about the surrounding world. Using a Head Mounted Display, the user of...

We demonstrate that it is possible to have a file facility
architecture where separate interfaces are provided for the basic file
service and transaction oriented file service. Thus, depending upon the
requirement a user can perform I/O on a file either using the semantics
of the basic file service or the transaction oriented file service. The
concept of stable storage is exploited to make our design very reliable.
To achieve the best possible performance we have successfully
established a very fruitful and yet new relationship among the storage
policy of file data and the methods to make changes in the intentions
list permanent to commit a transaction
In this paper a high performance and adaptive commit protocol is presented. The proposed protocol is the result of research into developing a very important relationship between the file storage strategy and techniques to commit transactions. It is demonstrated that the proposed protocol is capable of combining the powers of different methods for committing transactions.
