An Extensible Architecture for Avionics Sensor Health Assessment Using Data Distribution Service (Draft)

Avionics Sensor Health Assessment is a sub-discipline of Integrated Vehicle Health Management (IVHM), which relates to the collection of sensor data, distributing it to diagnostics/prognostics algorithms, detecting run-time anomalies, and scheduling maintenance procedures. Real-time availability of the sensor health diagnostics for aircraft (manned or unmanned) subsystems allows pilots and operators to improve operational decisions. Therefore, avionics sensor health assessments are used extensively in the mil-aero domain.

DARGOS: a Highly Adaptable and Scalable Monitoring Architecture for Multi-Tenant Clouds

One of the most important features in Cloud environments is to know the status and the availability of the physical resources and services present in the current infrastructure. A full knowledge and control of the current status of those resources enables Cloud administrators to design better Cloud provisioning strategies and to avoid SLA violations.

Standardizing the Data Distribution Service (DDS) API for Modern C++

Technical presentation give at BoostCon describing the new standard C++ PSM for the OMG DDS specification.

The new C++ language API to DDS takes advantage of the C++ standard features to create a simpler, safer, more compact API. This presentation describes the main features of the API as well as some of the technical design decisions and challenges.

Data Distribution Service for Industrial Automation

Master's Thesis in Intelligent Embedded Systems, School of Innovation, Design and Engineering, Marardalen University, Sweden.

This work focuses on applying DDS in the context of IEC 61499. The specific objectives are to: 1) present the structure and key feature of DDS, 2) map node-to-node communication in IEC 61499 to the DDS real-time publish-subscribe model including mapping timing requirements to QoS attributes of the publish-subscribe model, and 3) evaluate the performance of DDS communication while comparing it with the more traditional socket-based Ethernet communication.
