In the production enterprises, interoperability between information systems used is the key for a successfull Product Lifecycle Management approach. Despite many research works, the preservation of the information ow along the product life is still problematical because of the scienti c and technological locks existing. These locks are identi ed in this paper and a new federative approach of in...

Now days, manufacturers are focusing on increasing the concurrency in multiprocessor system-on-a-chip (MPSoC) architecture instead of increasing clock speed, for embedded systems. Traditionally lock-based synchronization is provided to support concurrency; as managing locks can be very difficult and error prone. Transactional memories and lock based systems have been extensively used to provide...

Storing, querying, and updating XML documents in multi-user environments requires data processing guarded by a transactional context to assure the well-known ACID properties, particularly with regard to isolate concurrent transactions. In this paper, we introduce the taDOM tree, an extended data model which allows finegrained lock acquisition for XML documents. For this reason, we design a tail...
