In this paper we introduce two methods for the construction of asymmetric multivariate copulas. The …rst is connected with products of copulas. The second approach generalises the Archimedean copulas. The resulting copulas are asymmetric and may have more than two parameters in contrast to most of the parametric families of copulas described in the literature. We study the properties of the pro...

This Document presents the findings to date for task 3.3 from work package 3 of eRENA (ESPRIT project 25379). It continues from deliverable 3.1 on a new area of research, i.e. Inhabited Television. We begin with summarising the evolution of digital broadcast as well as justifying mixed reality’s suitability to Inhabited TV, finally describing the current implementation – eTV. Specifically, this...

This report sumarizes the steps taken in the development of an accelerated version of the electrical circuit simulator CINNAMON. The architectural and functional features of an Alliant FX/4 computer are briely described and its use as the underlying hardware accelerator is outlined. This work was partially supported by the Esprit 1058 Project

We propose in this paper a historical perspective of programming issues found in the implementation of control systems, based on the author’s observations for more than fifteen years, but especially during the Crisys Esprit project. We show that in contrast with the asynchronous tradition of computer scientists, control engineers were naturally led to a synchronous practice that was later forma...

This article presents a new approach of implementing signal direction-of-arrival estimation, in which subarray beamforming is applied prior to estimation of signal parameters via rotational invariance techniques (ESPRIT). Different from the previous approaches, the beam-domain data from multiple adjacent pointing angles are combined in a way that the displacement invariance structure required b...

Two algorithms are proposed for estimating the quadratically coupled frequency pairs (QC pairs) in a signal consisting of complex sinusoids in white noise, which may be nongaussian in general. Three matrices are constructed from the complex third order moments of the noisy signal, the latter two being time shifted versions of the first. The list of coupled frequencies is obtained from the rank ...

Distributed memorymachines have been around for quite a long time, but, in spite of their excellent performance/price ratio, they are not widely used for scientiic applications. The main reason for that setback is that no compiler is available for these applications, usually written in Fortran, and for this machine architecture. We developped in PUMA Esprit Project a prototype compiler, taking ...

Content-based indexing methods are of great interest for image and video retrieval in audio-visual archives, such as in the Esprit project DiVAN that we are currently developing. Detecting and recognizing human faces automatically in video data provide users with powerful tools for performing queries. In this article, a new scheme for face recognition using a wavelet packet decomposition is pre...

Angle estimation for a bistatic MIMO radar system based on Unitary Esprit techniques is proposed in this study. The algorithm exploits the dual invariance in distinct directions and centrosymmetry of the bistatic MIMO radar system to provide real valued computations and automatically paired Directions of Departures (DOD) and Directions of Arrival (DOA) estimates. Simulation results show the eff...

A construction is described of a cartesian closed category . with exactly two elements out of a C-monoid that 9.can be recovered from A without reference to the construction. Note: The first author was partially supported by the Dutch government through the SPIN project PRISMA; the second author was partially supported by the EEC through Esprit project 415. We answer a question of Lambek and Sc...
