Speech recognition in a command and control workstation environment
No full textDistinguished Alumni Award Program author. RADM Michael A. LeFever, USN (Presented 30 May 06)This thesis investigates speech recognition in a command and control workstation environment. It discusses the Navy's need for a command and control workstation (CCWS) and the importance of the human interface design. In particular, it evaluates the performance of Stanford Research Institute International (SRI's) 1000 word discrete speech recognizer. The speech board is intended to be used in the Command and Control Multi-Media workstation being developed by SRI. Additionally, it investigates a VOTAN continuous recognizer (currently for use by research and commercial vendors) in an interactive warfare simulation game. The results indicate that speech recognition systems could increase the capability of the commander to input and access information, provide more rapid response to information desired or displayed, and enhance human interaction in the man-machine interface. Past, current, and future speech applications are discussedApproved for public release; distribution is unlimited.Lieutenant Commander, United States Navyhttp://archive.org/details/speechrecognitio109452283

Dynamical Behavior of the Fractional Goldbeter-Lefever Model
No full textDue to the importance of the historical memory in the analysis of a class of dynamical systems, weintroduce in this paper a time fractional-order derivative into the Goldbeter-Lefever model, which is a generalized form of its corresponding first-derivative model. For this system, we investigate the local stability of the proposed system, and we discuss the Hopf bifurcation. Some numerical simulations are performed to confirm the analytical obtained results

She explains the options students and employees have, and encourage WSU community to engage in healthy practices recommended by Sedgwick County officials, such as vaccination and wearing masks when appropriate
COLLE : a Matlab toolbox for solving the Lugiato-Lefever equation in the stationary regime
No full textCOLLE is a Matlab toolbox developed to solve the stationary Lugiato-Lefever equation (LLE) both for ring-shaped optical resonators and for Fabry-Perot optical resonators.
In optics, the stationary Lugiato-Lefever equation is a model for Kerr comb generation in optical resonators.
The Lugiato-Lefever equation for a ring-shaped optical resonator (RS-LLE) is solved by using a collocation method as implemented in Matlab bvp4c solver.
Since Matlab bvp4c solver can not handle the case of Lugiato-Lefever equation for a Fabry-Perot optical resonator (FP-LLE), we have implemented a dedicated approach based on a Finite Difference discretization of the FP-LLE together with a solving of the resulting system of non-linear equations by Matlab fsolve solver
pyLLE: a Fast and User Friendly Lugiato-Lefever Equation Solver
No full textWe present the development of pyLLE, a freely accessible and cross-platform Lugiato-Lefever equation solver programmed in Python and Julia and optimized for the simulation of microresonator frequency combs. Examples illustrating its operation, the simplicity of use, and performance against other programming language are presented.

The logic of the contradictory in the work of Tomás Lefever
No full textLa obra de Tomás Lefever (1926-2003) plantea una crítica orientada a desaprender los fundamentos musicales adquiridos como consecuencia de un expansivo determinismo racional para, en cambio, robustecer el carácter afectivo de su naturaleza expresiva. Este artículo sondea el terreno trazado por Lefever en textos y composiciones alrededor de un conjunto de nociones que provienen de la “lógica del antagonismo” formulada por el filósofo rumano-francés Stéphane Lupasco, y que acompañan a toda la obra del compositor. A partir de lo anterior, se inquiere en la perspectiva de su invención musical, específicamente en aquella fracción que Lefever denominó como partituras en potencia. Finalmente, se sostiene que la obra de Lefever constituye un espacio experimental en donde se pone en juego el dominio de la música por la vía de la improvisación como operación afectiva por antonomasia, y se examina su participación en el derrotero inaugurado por John Cage.The work of Tomás Lefever (1926-2003) proposes a critique aimed at unlearning the musical foundations acquired because of an expansive rational determinism in order, instead, to strengthen the affective character of its expressive nature. This article explores the terrain traced by Lefever in texts and compositions around a set of notions coming from the “logic of antagonism” formulated by the Romanian-French philosopher Stéphane Lupasco; notions emanating from this thought accompanied the whole work of the composer. Based on the above, we enquire into the perspective of his musical invention, specifically in that fraction that Lefever called as potential scores. Finally, it is argued that the work of Tomás Lefever constitutes an experimental space where the mastery of music through improvisation is put into play as an affective operation par excellence, in addition to examining his participation in the path inaugurated by John Cage

Stability of a stationary solution for the Lugiato-Lefever equation
No full textWe study the stability of a stationary solution for the Lugiato-Lefever equation with the periodic boundary condition in one space dimension, which is a damped and driven nonlinear Schrodinger equation introduced to model the optical cavity. In this paper, we prove the Strichartz estimates for the linear damped Schrodinger equation with potential and external forcing and investigate the stability of certain stationary solutions under the initial perturbation within the framework of .Articledepartmental bulletin pape
