Connections are a persistent challenge for traditional reinforced concrete construction and even more digital fabrication with (DFC). The latter, on the other hand, opens up new possibilities producing connections tailored geometries surface roughness. Based findings of an exploratory, experimental campaign, this paper discusses design, structural testing digitally fabricated joints using DFC t...

The density peaks clustering (DPC) algorithm is a novel density-based clustering approach. Outliers can be spotted and excluded automatically, and clusters can be found regardless of the shape and of dimensionality of the space in which they are embedded. However, it still has problems when processing a complex data set with irregular shapes and varying densities to get a good clustering result...

A bottleneck situation in one-lane traffic flow is typically modelled with a constant demand of entering cars. However, in practice this demand may depend on the density of cars in the bottleneck. The present paper studies a simple bimodal realization of this mechanism to which we refer to as density-feedback control (DFC): If the actual density in the bottleneck is above a certain threshold, t...

Modern feature-rich telecommunications services offer significant opportunities to human users. To make these services more usable, facilitating personalisation is very important since it enhances the users’ experience considerably. However, regardless how service providers organise their catalogues of features, they cannot achieve complete configurability due to the existence of feature intera...

We propose an adaptive modification of the delayed feedback control (DFC) method that automatically finds the optimal feedback gain of the DFC systems. The system under control is perturbed by a Gaussian white noise with a low amplitude, and the variance of the delayed difference is estimated by a simple integrator. The problem of minimization of the variance is substituted by a minimization of...

Dans l’étude des bases de données, il est intéressant de déceler les liens entre les attributs. Pour ça, plusieurs outils sont disponibles. Les Règles d’Association (RA) permettent de savoir quelles valeurs des attributs dépendent d’autres valeurs. Les Dépendances Fonctionnelles (DF) permettent de savoir quels attributs dépendent des autres. Les RA donnent des informations à un niveau de granul...

This paper shows how an engineer could write a full formal description of the service layer of a telecommunication system, organized according to the Distributed Feature Composition virtual architecture. Descriptions in Promela and Z can be composed using a joint semantics based on the transition-axiom method. The described system can be reasoned about in several ways, including use of tools de...

In response to the call for candidates issued by the National Institute for Standards and Technologies (the Advanced Encryp-tion Standard project) the Ecole Normale Sup erieure proposed a candidate called DFC as for \Decorrelated Fast Cipher", based on the decor-relation technique that provides provable security against several classes of attacks (in particular the basic version of Biham and Sh...
