A theoretically exact computational boundary is introduced, that is based on modal residual potentials for the spherical geometry. The boundary produces a set of first-order, uncoupled ordinary differential equations for nodal boundary responses, and a set of uncoupled time-stepping equations for modal boundary responses. The two sets are coupled through nodal-modal transformation based on the ...

Initial commissioning results from the PEP-II transverse coupled-bunch feedback systems are discussed. In particular, the performance of key hardware and coupled-bunch damping results are described in some detail. Beam dynamics related measurements presented include beam transfer functions and selected modal growth and damping rates.

A self-contained coupled-mode formulation for coupled two-dimensional photonic-crystal waveguides (PCWs) is discussed. Using a perturbation theory, the first-order coupled-mode equations are systematically derived, which govern the evolution of the modal amplitude of individual PCWs in isolation. The coupled-mode equations are used to analyze the coupled symmetric PCWs consisting of a square la...

We participated both in the photo annotation and conceptbased retrieval tasks of CLEF 2011. For the annotation task we developed visual, textual and multi-modal approaches using multi-label learning algorithms from the Mulan open source library. For the visual model we employed the ColorDescriptor software to extract visual features from the images using 7 descriptors and 2 detectors. For each ...

â â€œshodan” is a multifunctional verb in persian language. this paper deals with six different functions of “shodan” based on a purely formal approach. these functions are as follows: liking verb, light verb in some compound predicates, auxiliary verb, helping verb in passive voice, modal verb, and simple verb. the interface between lexicon and syntax, and the ways to show this relations...

This paper investigates the dynamics of the engine driveline system for achieving accurate and online diagnostics of engine conditions using instantaneous angular speed (IAS). Based on a state space modelling approach and key structures of the system, a torsional vibration model is developed and its modal properties: modal frequency, damping ratio and shapes are evaluated. Then taking the outpu...
