Wideband signals are expected to be used to achieve the required quality of service (QoS) in the next generation ofwireless communications, civil and military radar, and many wireless sensor network (WSN) scenarios. Widebandsignal detection has been identified as one of the most challenging problems in the proliferation of the cognitiveradio techno...
Wireless Sensors Networks (WSN) are more and more used in structural health monitoringapplications since they represent a less expensive and non-invasive way to monitorinfrastructures. Most of these applications work by merging or comparing data fromseveral sensors located across the structure. These data often comprise measurementsof physicals phe...
We present the Extended-Sub-domain Decomposition Iterative Method (E-SDIM), as the generalization of theSDIM, in order to rigorously solve the problem of electromagnetic scattering by a randomly rough and perfectlyconducting 2D surface. An iterative scheme is used to efficiently solve the linear system resulting from thediscretization by the Method...
Fluid flow in porous media is known to be ruled by relative permeability. The relative permeability itself is dramatically impacted by the wettability state of the medium. Wettability refers to the relative preference of a solid material for one fluid in a diphasic or multiphasic system. Despite its great impact in oil recovery, a proper characteri...
Systematic literature reviews (SRs) are a way of synthesising scientific evidence to answer a particular research question in a way that is transparent and reproducible, while seeking to include all published evidence on the topic and appraising the quality of this evidence. SRs have become a major methodology in disciplines such as public policy r...
Monitoring properly the circularity performance of technical products is a point of increasing importance. Yet, evaluating the circularity potential of products during (re)design and development phases is a challenging task. In this study, several C-indicators are experienced by doctoral students and industrialists through two workshops on a real-w...
Breakthrough technologies introduce a radically new capability or a drastic performance improvement. However, the existing engineering design literature does not specifically pay attention to them. In this paper, we present a conceptual framework for breakthrough technologies, aiming for a more detailed characterization of breakthrough technologies...
Current healthcare delivery challenges are multi-faceted, requiring multiple perspectives to be addressed using a systems approach. However, a significant amount of healthcare systems design research work is carried out within single disciplines or at best a few disciplines working together. There appears to be little deliberate attempt to draw tog...
In this paper, we firstly study the security enhancement of three steganographic methods by using a proposed chaotic system. The first method, namely the Enhanced Edge Adaptive Image Steganography Based on LSB Matching Revisited (EEALSBMR), is present in the spatial domain. The two other methods, the Enhanced Discrete Cosine Transform (EDCT) and En...
