Serial segment method for measuring remnant

For tracking tasks where a sum of sine waves forcing function is used it is often difficult and/or expensive to obtain the pilot's remnant in the vicinity of the sine waves. For the case where each sine wave has at least four times an integer number of cycle per run length, this paper illustrates the serial segments method for measuring remnant power spectral density in a frequency band centered on each sine wave. This method can be implemented on digital, hybrid, or analog Fourier coefficient analyzers, and is particularly advantageous on the latter since properties of Fourier coefficients are exploited to yield both a remnant measure and an improved estimate of the correlated component

Roll tracking effects of G-vector tilt and various types of motion washout

In a dogfight scenario, the task was to follow the target's roll angle while suppressing gust disturbances. All subjects adopted the same behavioral strategies in following the target while suppressing the gusts, and the MFP-fitted math model response was generally within one data symbol width. The results include the following: (1) comparisons of full roll motion (both with and without the spurious gravity tilt cue) with the static case. These motion cues help suppress disturbances with little net effect on the visual performance. Tilt cues were clearly used by the pilots but gave only small improvement in tracking errors. (2) The optimum washout (in terms of performance close to real world, similar behavioral parameters, significant motion attenuation (60 percent), and acceptable motion fidelity) was the combined attenuation and first-order washout. (3) Various trends in parameters across the motion conditions were apparent, and are discussed with respect to a comprehensive model for predicting adaptation to various roll motion cues

Topological gravitation on graph manifolds

A model of topological field theory is presented in which the vacuum coupling constants are topological invariants of the four-dimensional spacetime. Thus the coupling constants are theoretically computable, and they indicate the topological structure of our universe.Comment: 3 pages, a talk delivered at the 11th Marcel Grossmann Meeting (2006

The Image of Valladolid in William Dean Howells’ Familiar Spanish Travels (1913): Romanticism or Realism?

El objeto de estudio del presente trabajo de investigación será el análisis de la imagen de Valladolid que se proyecta en Familiar Spanish Travels, libro de viajes publicado por el critico y escritor realista norteamericano William Dean Howells en 1913, tras su breve estancia en España en 1911. Con este objetivo, el ensayo se dividirá en cuatro apartados: (1) una base teórica esencial para entender la obra de Howells – abarcará las nociones de literatura de viajes, Orientalismo español e Hispanismo en los Estados Unidos; (2) un acercamiento biográfico al autor en relación con su pasion por España (apartado basado en tanto en fuentes externas como en el comentario de Familiar Spanish Travels: “Capítulo I. Acercamientos Autobiográficos” de Howells; (3) el análisis y comentario crítico de la imagen de Valladolid en el libro; y (4) la presentación de conclusiones.Departamento de Filología InglesaGrado en Estudios Inglese
