Abstract
The Airline Operations Control Centre (AOCC) tries to solve unexpected problems during the airline operation. Problems with aircraft, crew members and passengers are common and very hard to solve due to the several variables involved. This paper presents the implementation of a real-world multi-agent system for operations recovery in an airline company. The analysis and design of the system was done following a GAIA based methodology. We present the system specification as well as the implementation using JADE. A case Study is included, where we present how the system solved a real problem.

Abstract
Nowadays the total sum of Distributed Generation (DG) in the Portuguese Distribution Network (DN) is extremely significant. Previously, load shedding schemes were designed without taking into consideration this type of generation. In this paper, the Portuguese Electrical System is studied through a static analysis using real data, and the new relay parameters to be applied in substations are evaluated, continuously bearing in mind the strict coordination with those of the DN. In order to achieve these purposes, an algorithm was developed to rank possible candidate substation feeders to the load shedding plan, using Ms Excel to process data and perform the calculations. The obtained results show that by using the designed algorithm it is possible to find a systematic process for determining under-frequency relay parameters considering the trade-off between shedding critical consumers and shedding DG. © 2009 IEEE.

Abstract
This study was carried out to improve diagnosis and prediction of geomaterials status from coastal protection structures. A methodology is proposed for the characterization of rock materials and management of the structures. The characterization was organized in different phases: i) visual inspection; ii) field techniques to study geologic-geotechnical features; iii) in situ measurement of geomechanical parameters; and iv) development of GIS-based mapping and assessment of the block materials. The results obtained allowed to define a geotechnical zonation for the structure armor layer, according to the type of geomaterial source, weathering/degradation grade and geomechanical rebound values. The GIS project developed, combined an applied cartography of the groins' superficial layer with the results of the field techniques. The interactive base included the pilot case presented in this work, from Espinho coastal area (NW Portugal, Iberian Peninsula), which comprises four different sectors. The results of this work, support the need to apply geomechanic concepts to coastal structures, since they allow the evaluation of deterioration levels and improve the planning of intervention works. This methodology contributes to ameliorate the efficiency of monitoring and maintenance, in an economically beneficial mode. © ISRM International Symposium on Rock Mechanics, SINOROCK 2009.

Abstract
This paper describes the strategy and implementation details of a cooperative agent team for the CiberMouse@RTSS08, a, robotics simulation competition. The paper introduces several concepts concerning cooperative robotics, giving all overview of its applications and challenges. It also presents the CiberMouse@RTSS08 competition rules and the associated simulation system. The proposed approach is based oil a deliberative architecture, thus providing an autonomous intelligent behaviour. A probabilistic mapping procedure, based on the Bayes' theorem, is used to maintain all internal world state. Quadtrees and A* are used for path planning and plan execution. A specific methodology was developed for beacon finding. The agents cooperate oil exchanging world and beacon information. In order to overcome the simulator's broadcasting distance limitation, a communication network between the agents was, created. The paper analyses the impact; of cooperation on this particular problem, by comparing the team's performance in four different situations: communication with network and beacon exchanging, communication without network, communication without beacon exchanging and no communication at all.

Abstract
The effects of delta mesons on the dynamical instabilities of cold and warm nuclear and stellar matter at subsaturation densities are studied in the framework of relativistic mean-field hadron models (NL3, NL rho, and NL rho delta) with the inclusion of the electromagnetic field. The distillation effect and the spinodals for all the models considered are discussed. The crust-core transition density and pressure are obtained as a function of temperature for beta-equilibrium matter with and without neutrino trapping. An estimation of the size of the clusters formed in the nonhomogeneous phase and the corresponding growth rates are made. It is shown that cluster sizes increase with temperature. The effects of the delta meson on the instability region are larger for low temperatures, very asymmetric matter, and densities close to the spinodal surface. It increases the distillation effect above similar to 0.4 rho(0) and has the opposite effect below that density.

Abstract
This study was carried out to develop a systematic methodology for the analysis of coastal protection structures in a GIS database project. This work contributes to ameliorate the efficiency of monitoring and maintenance, in an economically beneficial mode. Low-level aerial surveys were conducted from a light aircraft, providing high-resolution digital images Suitable for armour layer integrity analysis. Combining photogrammetric and field techniques, this research aims to define an applied cartography for geomaterials characterisation in hydraulic works. This research comprehends different phases: i) Visual inspection; ii) field techniques to study geologic-geotechnical features; iii) in situ measurement of geomechanical parameters; and iv) development of GIS mapping and assessment of the block materials. The GIS project incorporates high-resolution aerial imagery surveys and the results of the field techniques applied for the structures' cartography. The interactive base included the pilot case presented in this work, from Espinho coastal area (NW Portugal), which comprises five sectors. Based on the described methodology, different geomaterials were recognised, providing an evaluation of the current condition of the structure and the revetment material status. The results obtained allowed to define a geomaterial zonation for the structures' armour layer, according to the type of rock source, weathering/degradation grade and in situ, geomechanical tests. Also, the outcome established by these results indicates the need for repairing/maintenance works in some parts of the studied structures. This guidance may be helpful during pre-design or planning assessments, supported by coastal geoengineering concepts. It also generates useful knowledge for repairing recommendations and conceptual coastal management.
