“Design, Development, Integration and Sea Trials of ROVLatis : A Smart Remotely Operated Tethered Underwater Vehicle”
Dr.Hammad Ahmad, Univ. of Limerick Ireland
Abstract
An ROV is a remotely operated Underwater Vehicle. ROVs are controlled and powered remotely from the surface via a tether cable and are designed to operate in underwater environments which are hostile or inaccessible to human divers. ROVLatis is the first such vehicle designed, built and tested in Ireland. ROVLatis has been developed for ocean exploration, high-resolution seabed mapping, marine environment monitoring and operations supporting roll-out of Ocean Energy Devices. It is designed to operate from the beach out to the edge of the continental shelf at depths of 1,000m and more. The smart technologies deployed on Latis are cutting edge, with advanced integrated control systems incorporating auto-pilot, fault-tolerant thruster control and Pilot aiding tools/simulation for practice / training of complex operations prior to execution in the real world. The vehicle is equipped with the latest in sidescan and multibeam sonar and vision-based navigation with patented data capture from several acoustic devices simultaneously. Featuring capabilities normally only found on much larger work class ROVs, Latis' smaller footprint allows it to be deployed more cost effectively from smaller inshore vessels.

Celestijenlaan 200A 05.01 (5th floor)
"Quarterly Meeting of OPTEC Working Group 3 on Parameter and State Estimation"
Next WG3 meeting takes place Friday 29 April from 09.00 to 11.00 in
Computer Science room A05.01 (5th floor).
Important:
- We will make the list of parameter estimation software used during the
meeting, so everyone is kindly asked to think of the parameter
estimation software he/she uses. As suggested, this list will be put on
the intranet such that it can be accessed by any OPTEC member.
- The idea is also to start some joint reading of parameter estimation
book(s). So everyone is invited to propose an interesting book to be read.
Agenda:
09.00-09.10: Welcome and agenda
09.10-09.20: Update
09.20-09.50: OED in biochemical systems (Eva Van Derlinden)
09.00-10.00: Break
10.00-10.20: Compilation of list of software used
10.20-10.40: Book reading: start-up discussion
10.40-11.00: Varia

Dynamic Resource Allocation of Partial Crosstalk Cancellation in DSL networks"
Beier Li
The data rate performance of DSL broadband access networks is severely degraded by crosstalk among the different copper lines. The linear zero-forcing partial crosstalk cancellation (PCC) is a promising technique to mitigate the crosstalk. Other than the data rate performance, the delay performance is also very important for the user's experience. In this talk we introduce a set dynamic resource allocation algorithms of PCC in DSL networks, which can improve the data rate performance of PCC and meanwhile take the consideration of delay performance into account. The resource allocation at each time slot is formulated as weighted-sum optimization problem with constraints, and is solved efficiently through dual decomposition. Moreover, the adaptation of the resource budget parameter at each time slot is seen to have similarities with the tuning procedure of Lagrange multipliers as known from optimization theory.
