Due to their performance and flexibility, dynamically reconfigurableFPGA-based systems on chip find their uses in industry. Thosearchitectures require dynamic context management of their computingresources to adapt to their environment.Our manager dynamically changes the application quality scenarios tofulfill the system’s constraints. Based on a h...
Massive MIMO and filtered multi-carrier waveforms are considered as key enabling technologies for next-generation wireless networks. In this work, the Filter Bank Multi-Carrier (FBMC) waveform solution applying our previously proposed short filter and advanced receivers is extended to massive MIMO systems and evaluated in comparison to OFDM. Simula...

Anomaly detection is a crucial aspect of embedded applications. However, limited computational power, evolving environments or lack of training data are difficulties that can limit anomaly detection algorithms. Anomaly detection can be performed by one class classification algorithms to remove the need for anomalous data in the training set. This p...
The performances of two microstrip patch antennas with low visual impact are presented in this paper and compared to an opaque solution. These consist in a copper film deposited on a Borofloat 33 glass substrate through a thin titanium gripping layer. The mesh is obtained by wet chemical etching. Antennas differ by the dimensions in the ground plan...

This paper presents a multifunctional battery-free wireless sensing node (SN) designed to monitor physical parameters (e.g., temperature, humidity and resistivity) of reinforced concrete. The SN, which is intended to be embedded into a concrete cavity, is autonomous and can be wirelessly powered thanks to the wireless power transmission technique. ...
The separation of several regions of interest in an image constitutes an frequent, important, and particularly challenging task in artificial intelligence, typically known as image segmentation. The difficulties found when approaching this problem include but are not limited to the presence of several types of noise, varying focus, shadows, reflect...
Given two or more concentrations, an interesting and important related issue concerns the quantification of how strongly they are spatially interrelated. The concept of colocalization has been frequently considered as an indication of the tendency of the values of two concentrations to spatially vary together. While this frequently adopted approach...
The spinal cord is a major structure of the central nervous system allowing, among other things, the transmission of afferent sensory and efferent motor information. During spinal surgery, such as scoliosis correction, this structure can be damaged, resulting in major neurological damage to the patient. To date, there is no direct way to monitor th...
