Publications
Main Projects I am involved in

Description: The CERBERO EU project aims at developing a design environment for Cyber-Physical Systems based on two pillars:
1. a cross-layer model-based approach to describe, optimize, and analyze the system and all its different views concurrently, and
2. an advanced adaptivity support based on a multilayer autonomous engine.
The targeted three applications of CERBERO are a self-healing system for planetary exploration, unmanned vehicles for ocean monitoring and a smart travel network for electric vehicles.
|
Description: The COMPACT-SL-MODELS project, financed by US National Science Foundation, develops new techniques to help advanced computing systems for signal processing better adapt to the environments in which they operate.
|
 |
Description: The ARTEFaCT project aims to ease the design of energy efficient circuits by using approximate computing techniques. The project will contribute along three main research directions:
1- Approximate, ultra low-power circuit design,
2- Modeling and analysis of variable levels of computation precision in applications
3- Accuracy-energy trade-offs in software.

Description: The aim of the ANR HPeC project is to develop self-adaptive, energy-efficient high performance embedded computing in the context of Unmanned Aerial Vehicles.
|
 |
Description: The aim or the FUI GreenVIDEO project is to study and develop mechanisms for reducing energy consumption of image/video creation, transformation, broadcast and rendering.
