Designing embedded system is a non-trivial task during which wrong choices can lead to extremely costly re-design loops. The extra cost is even higher when wrong choices are made during the algorithm speci cation and mapping over the selected architecture. In this paper we propose a high-level approach for design space exploration, based on a usual standard(More)
The purpose of the current investigation was to study the effect of Ca2+ (0, 3.5 and 20 mM concentrations) on the antioxidant systems in the halophyte Cakile maritima under NaCl stress (0, 100, 200 and 400 mM NaCl). Plants treated with both moderate calcium (3.5 mM) and salt levels (100 mM) showed the maximum growth, and the addition of 20 mM calcium to the(More)
The objective of this study was to see whether a mathematical model of fracture healing was able to mimic bone formation around an unloaded screw-shaped titanium implant as it is well-believed that both processes exhibit many biological similarities. This model describes the spatio-temporal evolution of cellular activities, ranging from mesenchymal stem(More)
Media-processing applications, such as signal processing, 2D and 3D graphics rendering, and image compression, are the dominant workloads in many embedded systems today. The real-time constraints of those media applications have taxing demands on today's processor performances with low cost, low power and reduced design delay. To satisfy those challenges, a(More)
Though halophytes are naturally adapted to salinity, their salt-tolerance limits are greatly influenced by their provenance and developmental stage. In the present study, physio-biochemical responses of two Tunisian ecotypes of the oilseed coastal halophyte Cakile maritima (Brassicaceae) to salinity (0–400 mM NaCl) were monitored during germination and(More)
This Embeddd systems use emerges in the electronic field. Many applications have been embedded such as network, image processing, signal processing ... The emergency of multimedia applications particularly in mobile embedded systems puts new challenges for the design of such systems. The major difficulty is the embedded system’s reduced computational(More)
This paper deals with the reactive control of an autonomous mobile robot which should move safely in a unknown three-dimensional(3D) environment to reach a desired goal. In order to proceed with the problem, we propose a hybrid approach based on fuzzy logic controller (FLC) for goal seeking behavior and Deformable Virtual Zone (DVZ) reactive algorithm to(More)
The main aim of this work is to propose a HMI alternative for hands-free control of an electrical wheelchair using both face and eyes information. An image processing based technique for the guidance of an electrical wheelchair is used. As processing unit, we choose the Panda board ES development kit based on the TI OMAP 4 SoC (System on Chip). This board(More)
