[EN]In recent years, several historical rock art sites have been located in Alcazar de San. Given its fragility, one of the most important and urgent tasks being undertaken within the framework of the DIPAR research project is the documentation of these sites. Among the various techniques used to this, two stand out above the rest: the application of digital photography at night, and three-dimensional documentation.

Networked control over data networks has received increasing attention in recent years. Among many problems in networked control systems (NCSs) is the need to reduce control latency and jitter and to deal with packet dropouts. This paper introduces our recent progress on a queuing communication architecture for real-time NCS applications, and simple strategies for dealing with packet dropouts. Case studies for a middle-scale process or multiple small-scale processes are presented for TCP/IP based real-time NCSs. Variations of network architecture design are modelled, simulated, and analysed for evaluation of control latency and jitter performance. It is shown that a simple bandwidth upgrade or adding hierarchy does not necessarily bring benefits for performance improvement of control latency and jitter. A co-design of network and control is necessary to maximise the real-time control performance of NCSs
