Time travel has always been a fascinating topic in literature and physics. In cryptography, one may wonder how to keep data confidential for some time. In this dissertation, we will study how to make private information travel to the future. This dissertat ...
The present invention concerns a computer-implemented method for secure data exchange between a sender (A) and a recipient (B), wherein the method is performed by the sender (A) and comprises encrypting data using a symmetric key k, creating a write transa ...
Le projet s'inscrit dans le prolongement de mon étude théorique sur la compréhension et l'évolution d'un système traditionnel agraire en milieu himalayen, et des conséquences d'une ouverture récente au tourisme, à l'occupation militaire et à un système éco ...
Dissolution of Fe(III) phases is a key process in making iron available to biota and in the mobilization of associated trace elements. Recently, we have demonstrated that submicromolar concentrations of Fe(II) significantly accelerate rates of ligand-contr ...
In this work we present a new fabrication technique to print thin dielectric elastomer actuators (DEAs), reducing the driving voltage below 300 V while keeping good actuation performance. With operation voltages in the kV-range, standard DEAs are limited i ...
L'évolution des sciences et des techniques a favorisé le développement d'un système économique fondé sur une croissance sans limite, entraînant de profonds bouleversements. La dissolution du lien social et les menaces environnementales suscitent de plus en ...
The Data Encryption Standard (DES) is a cryptographic algorithm, designed by IBM, that was selected to be the national standard in 1977 by the National Bureau of Standards. The algorithm itself was entirely published but the design criteria were kept secre ...
L'habitat traditionnel est porteur de nombreuses réflexions dès lors qu'il entre en rupture avec les modes de vie contemporains. Comment perpétuer les qualités du patrimoine bâti et immatériel qu'il constitue, tout en proposant aux habitants un lieu de vie ...
Recently, ISO/IEC standardized a dataflow-programming framework called Reconfigurable Video Coding (RVC) for the specification of video codecs. The RVC framework aims at providing the specification of a system at a high abstraction level so that the functi ...
L’évaluation parasismique des constructions existantes est plus exigeante que le dimensionnement des constructions neuves. En effet, il est primordial de cerner au mieux le comportement sismique réel des structures existantes afin notamment d’éviter de coû ...
