Identity configurations across love and work in emerging adults in romantic relationships
2014
Love and work constitute two life-defining identity domains for emerging adults. The present study utilized a five-dimensional identity model and examined identity configurations across these two domains, capturing the degree to which identity statuses correspond across domains. A sample of German 18–30-year-olds who were either working or studying and engaged in a romantic relationship was assessed at baseline and three years later. Six identity clusters emerged in each domain. Combining identity clusters across love and work domains, 7 identity configurations were distinguished. Whereas some configurations were characterized by strong commitments in one or both domains, other configuratio…
Biometric sensors rapid prototyping on field-programmable gate arrays
2015
AbstractBiometric user authentication in large-scale distributed systems involves passive scanners and networked workstations and databases for user data acquisition, processing, and encryption. Unfortunately, traditional biometric authentication systems are prone to several attacks, such as Replay Attacks, Communication Attacks, and Database Attacks. Embedded biometric sensors overcome security limits of conventional software recognition systems, hiding its common attack points. The availability of mature reconfigurable hardware technology, such as field-programmable gate arrays, allows the developers to design and prototype the whole embedded biometric sensors. In this work, two strong an…
Mechanism of Antibacterial Activity via Morphology Change of α-AgVO3: Theoretical and Experimental Insights
2017
The electronic configuration, morphology, optical features, and antibacterial activity of metastable α-AgVO3 crystals have been discussed by a conciliation and association of the results acquired by experimental procedures and first-principles calculations. The α-AgVO3 powders were synthesized using a coprecipitation method at 10, 20, and 30 °C. By using a Wulff construction for all relevant low-index surfaces [(100), (010), (001), (110), (011), (101), and (111)], the fine-tuning of the desired morphologies can be achieved by controlling the values of the surface energies, thereby lending a microscopic understanding to the experimental results. The as-synthesized α-AgVO3 crystals display a …

Extensions of the witness method to characterize under-, over- and well-constrained geometric constraint systems
2011
International audience; This paper describes new ways to tackle several important problems encountered in geometric constraint solving, in the context of CAD, and which are linked to the handling of under- and over-constrained systems. It presents a powerful decomposition algorithm of such systems. Our methods are based on the witness principle whose theoretical background is recalled in a first step. A method to generate a witness is then explained. We show that having a witness can be used to incrementally detect over-constrainedness and thus to compute a well-constrained boundary system. An algorithm is introduced to check if anchoring a given subset of the coordinates brings the number …
A nonlinear oscillators network devoted to image processing
2004
A contrast enhancement and image inverting tool using a lattice of uncoupled nonlinear oscillators is proposed. We show theoretically and numerically that the gray scale picture contrast is strongly enhanced even if this one is initially very small. An image inversion can be also obtained in real time with the same Cellular Nonlinear Network (CNN) without reconfiguration of the network. A possible electronic implementation of this CNN is finally discussed.
Integrability and Non Integrability of Some n Body Problems
2016
International audience; We prove the non integrability of the colinear 3 and 4 body problem, for any positive masses. To deal with resistant cases, we present strong integrability criterions for 3 dimensional homogeneous potentials of degree −1, and prove that such cases cannot appear in the 4 body problem. Following the same strategy, we present a simple proof of non integrability for the planar n body problem. Eventually, we present some integrable cases of the n body problem restricted to some invariant vector spaces.

Méthodologie de conception de haut niveau pour la génération automatique des systèmes dynamiquement reconfigurables en utilisant IP-XACT et le profil…
2013
The main contribution of this thesis consists on the proposition and development a Model-driven Engineering (MDE) framework, in tandem with a component-based approach, for facilitating the design and implementation of Dynamic Partially Reconfigurable (DPR) Systems-on-Chip. The proposed methodology has been constructed around the Metadata-based Composition Framework paradigm, and based on common standards such as UML MARTE and the IEEE IP-XACT standard, an XML representation used for storing metadata about the IPs to be reused and of the platforms to be obtained at high-levels of abstraction. In fact, a componentizing process enables us to reuse the IP blocks, in UML MARTE, by wrapping them …
