Analytical design of nonlinear optical loop mirrors for fiber-optic communication systems

2006

International audience; We propose an easy and efficient method for analytically designing nonlinear optical loop mirrors (NOLMs) for fiber-optic communication systems. This analytical design is based on a Taylor series expansion of the transfer function of the NOLM, from which highly stable dynamical regimes can be readily obtained for any desired pulse parameters. We present numerical simulations showing dramatically improved performances in a 160 Gb/s transmission system that incorporates the NOLMs designed analytically.

Stiffness-Adaptive Taylor method for the integration of non-stiff and stiff kinetic models

1992

A systematic derivation procedure that greatly facilitates the application of the Taylor method to the integration of kinetic models is developed. In addition, an algorithm that gives the integration step as a function of the required level of accuracy is proposed. Using the Taylor method, application of this algorithm is immediate and largely reduces the integration time. In addition, a new method of integration of kinetic models, whose most important feature is the self-adaptability to the stiffness of the system along the integration process, is developed. This “stiffness-adaptive” Taylor method (SAT method) makes use of several algorithms, combining them to meet the particular requireme…

What culture must be recognised in the politics of multiculturalism?

2009

Liberalism offers a very broad range of responses and theoretical constructions when it comes to addressing the issue of the cultural diversity of societies and their cultural management. Compare the responses of Charles Taylor, Clifford Geertz and Michael lgnatieff, to name three important thinkers. They all claim to defend liberalism, but their viewpoints are very different. I have chosen these three because they come from three different disciplinary fields: philosophy, empirical anthropology and political theory.My purpose is to show that their differences do not derive only from their different political sensibilities, from the position they adopt within the broad spectrum of liberalis…

La religión en el mundo secular : trascendencia e individualidad. Un estudio del problema desde el pensamiento de Charles Taylor

2013

Las teorías clásicas del secularismo vaticinaron, durante decenios, el lento declinar de las religiones, su marginación al espacio privado y, finalmente, su disolución y muerte. Con todo, las profecías seculares no se han cumplido. Las religiones siguen gozando de relativa buena salud y siguen estado muy presentes en el espacio público. De esta manera, la religión está siendo ¿y vaticinamos que lo seguirá siendo en el futuro- un fenómeno importante, que continuará marcando, de una u otra manera, nuestra cultura, y que seguirá siendo un interlocutor significativo, con capacidad de aportar constructivamente en los distintos debates que se generen en el espacio público. Por esto se hace necesa…

Bacteria of the Genus Roseobacter Associated with the Toxic Dinoflagellate Prorocentrum lima

1998

The dinoflagellate Prorocentrum lima is known to produce diarrhetic shellfish poisons. However, it is yet unclear if the dinoflagellates themselves or the bacteria associated with them produce the toxins. Here we analyze the toxicity as well as the spectrum of bacteria in two cultures of P. lima, namely P. lima-SY and P. lima-ST, which initially derived from the same P. lima strain PL2V. Toxicity tests, applying the Artemia bioassay revealed in both cultures high levels of toxins. The bacteria, associated with the two cultures, were identified by PCR/nucleotide sequence analysis of the 16S rRNA gene. From cultures of P. lima-SY the dominant sequence was found to share a 93.7% similarity wit…

Towards an efficient meshfree solver

2016

In this paper we focus on the enhancement in accuracy approximating a function and its derivatives via smoothed particle hydrodynamics. We discuss about improvements in the solution by reformulating the original method by means of the Taylor series expansion and by projecting with the kernel function and its derivatives. The accuracy of a function and its derivatives, up to a fixed order, can be simultaneously improved by assuming them as unknowns of a linear system. The improved formulation has been assessed with gridded and scattered data points distribution and the convergence has been analyzed referring to a case study in a 2D domain.

Approximate Taylor methods for ODEs

2017

Abstract A new method for the numerical solution of ODEs is presented. This approach is based on an approximate formulation of the Taylor methods that has a much easier implementation than the original Taylor methods, since only the functions in the ODEs, and not their derivatives, are needed, just as in classical Runge–Kutta schemes. Compared to Runge–Kutta methods, the number of function evaluations to achieve a given order is higher, however with the present procedure it is much easier to produce arbitrary high-order schemes, which may be important in some applications. In many cases the new approach leads to an asymptotically lower computational cost when compared to the Taylor expansio…
