Matrix Quantization of Turbulence

Based on our recent work on Quantum Nambu Mechanics \cite{af2}, we provide an explicit quantization of the Lorenz chaotic attractor through the introduction of Non-commutative phase space coordinates as Hermitian $N \times N$ matrices in $R^{3}$. For the volume preserving part, they satisfy the commutation relations induced by one of the two Nambu Hamiltonians, the second one generating a unique time evolution. Dissipation is incorporated quantum mechanically in a self-consistent way having the correct classical limit without the introduction of external degrees of freedom. Due to its volume phase space contraction it violates the quantum commutation relations. We demonstrate that the Heisenberg-Nambu evolution equations for the Matrix Lorenz system develop fast decoherence to N independent Lorenz attractors. On the other hand there is a weak dissipation regime, where the quantum mechanical properties of the volume preserving non-dissipative sector survive for long times.Comment: 14 pages, Based on invited talks delivered at: Fifth Aegean Summer School, "From Gravity to Thermal Gauge theories and the AdS/CFT Correspondance", September 2009, Milos, Greece; the Intern.

IMPLEMENTACIÓN EN SIMUL8 DE UN MODELO SOBRE LOS DEPARTAMENTO DE ACCIDENTES Y EMERGENCIAS

Los departamentos de accidentes y emergencias son de gran interés en el área de la simulación de eventos discretos ya que por la importancia de los servicios que prestan se hace apremiante encontrar alternativas que hagan que su rendimiento en cuanto a tiempos de atención sea lo más óptimo posibles. En este trabajo se implementa en el software Simul8 un modelo genérico desarrollado por Günal y Pidd (2006) sobre estos departamentos con el fin de comprender el funcionamiento de estos sistemas y obtener respuestas de investigación sobre la implementación de modelos genéricos y la pertinencia de la simulación de eventos discretos para este tipo de sistemas.The departments of accidents and emergencies are very interesting in simulation and discrete events areas because the importance of the services that they give became important to find alternatives to make their performance in time attention the most optimal. In this work it’s carried out in the software Simul8 a generic model developed by Günal y Pidd (2006) about these departments in order to understand the performance of these systems and to get research answers about the carrying out of generic models and the relevance of simulation of discrete events for this kind of systems
