In the context of ESA Climate Change Initiative project, a new coastal sea level altimetry product has been developed in order to support advances variability studies. Measurements from Jason-1,2&3 missions have retracked with Adaptive Leading Edge Subwaveform (ALES) Retracker and then ingested X-TRACK software best possible set corrections. These two processing approaches, previously successfu...

In this paper we describe the Secure Method Invocation (SMI) framework implemented for Jason, our Javacard As Secure Objects Networks platform. Jason realises the secure object store paradigm, that reconciles the card-as-storage-element and card-as-processing-element views. In this paradigm, smart cards are viewed as secure containers for objects, whose methods can be called straightforwardly a...

We consider interactions between atomic intentions and plan failures in the Jason BDI-based agent programming language. Atomic intentions allow the agent developer to control the execution of intentions in situations where a sequence of actions must be executed ‘atomically’ in order to ensure the success of a plan. However, while atomic intentions in Jason enforce mutual exclusion, they are not...

Form Approved OMB No. 0704-0188 Public reporting burden for this collection of information is estimated to average 1 hour per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing this collection of information. Send comments regarding this burden estimate or any other aspect of this coll...

MAS research pushes the notion of openness related to systems combining heterogeneous computational entities. Typically, those entities answer to different purposes and functions and their integration is a crucial issue. Starting from a comprehensive approach in developing agents, organizations and environments, this paper devises an integrated approach and describes a unifying programming mode...

Almost one year of TOPEX/Poseidon (T/P) and Jason-1 data are processed to analyze the contribution of the tandem mission to mesoscale studies. To merge T/P and Jason-1 sea level anomaly (SLA) data, the main difficulty is to estimate consistent mean profiles for the two missions. An ocean variability correction is thus applied to T/P data before computing the mean profile. As a result, T/P and J...
