Performance of band-limited baseband synchronous CDMA using the orthogonal Independent Component Analysis (ICA) spreading sequences is compared with that using the Walsh-Hadamard sequences. The system we focus on here is where the transmitted signal powers after passing band-limiting filter are not controlled. The orthogonal ICA sequences are generated by ICA. We use ICA not as separator for re...

We show that the Bers embedding of the Teichmüller space of a once-punctured torus converges to the cardioid in the sense of Carathéodory up to rotation when the base torus goes to the boundary of its moduli space.

We prove that the Bers and Maskit slices of the quasi-Fuchsian space of a once-punctured torus have a dense, uncountable set of points in their boundaries about which the boundary spirals infinitely.

Recently the author has presented a new approach to solving coefficient problems for holomorphic functions based on deep features of Teichmüller spaces. It involves Bers isomorphism theorem spaces punctured Riemann surfaces. The aim present paper is provide applications this and extend indicated results more general classes functions.

In this paper we give a uni ed description of the archimedean and the totally split degenerate bers of an arithmetic surface, using operator algebras and Connes' theory of spectral triples in noncommutative geometry.

An injective map from the vertex set of a graph G—its order may not be finite—to the set of all natural numbers is called an arithmetic (a geometric) labeling of G if the map from the edge set which assigns to each edge the sum (product) of the numbers assigned to its ends by the former map, is injective and the range of the latter map forms an arithmetic (a geometric) progression. A graph is c...

Chaos-based communication systems are known to offer advantages that are shared by spread-spectrum communications. One important aspect of the performance of any spread-spectrum communication system is the ability to resist jamming. In this paper, an analysis of the antijamming performance of a coherent chaos shift keying system under the influence of a common pulsed-noise jammer is presented. ...

We provide an upper bound on the `2–torsion of a free-bycyclic group, −ρ(2)(F oΦ Z), in terms of a relative train-track representative for Φ ∈ Aut(F). Our result shares features with a theorem of Lück–Schick computing the `2–torsion of the fundamental group of a 3–manifold that bers over the circle in that it shows that the `2–torsion is determined by the exponential dynamics of the monodromy. ...

We propose to implement a \multi-argus" facility at CFHT. The main scientiic driver of this project is the study of the evolution of the Tully-Fisher relation at intermediate redshift, thanks to the use of the optical rotation curves of spiral galaxies. The multiplex gain makes this project quite attractive, even on a 4m-size telescope such as CFHT. From the instrumental side, the idea is to mo...
