This paper presents the sensitivity analysis of the behavior of a synchronous machine using the winding function theory considering the effect of static air-gap eccentricity. The winding function theory as a method to calculate the inductances of synchronous machines from the geometry and the actual arranging of the windings is presented. Then, detailed numerical simulations are carried out to ...

The effect of retinal eccentricity on stimulus identification was investigated by measuring observers' ability to identify digits of various sizes presented briefly at different locations in their visual fields. The stimuli were either presented one at a time or presented in pairs with each member of the pair at a different eccentricity and having a different size. Stimulus-response confusion m...

We study the dynamic self-assembly and propulsion of a ribbon formed from paramagnetic colloids in a dynamic magnetic field. The sedimented ribbon assembles due to time averaged dipolar interactions between the beads. The time dependence of the dipolar interactions together with hydrodynamic interactions cause a twisted ribbon conformation. Domain walls of high twist connect domains of nearly c...

In a clinical setting, emphasis is given to foveal visual function, and tests generally only utilize static stimuli. In this study, we measured static (SVA) and dynamic visual acuity (DVA) in the central and peripheral visual field on healthy, young emmetropic subjects using stationary and drifting Gabor patches. There were no differences between SVA and DVA in the peripheral visual field; howe...

The Minimum Eccentricity Shortest Path Problem consists in finding a shortest path with minimum eccentricity given undirected graph. problem is known to be NP-complete and W[2]-hard respect the desired eccentricity. We present fpt-algorithms for parameterized by modular width, distance cluster graph, combination of treewidth eccentricity, maximum leaf number.

the wiener index w(g) of a connected graph g is defined as the sum of the distances betweenall unordered pairs of vertices of g. the eccentricity of a vertex v in g is the distance to avertex farthest from v. in this paper we obtain the wiener index of a graph in terms ofeccentricities. further we extend these results to the self-centered graphs.

We explored the buildup and decay of threshold elevation during and after adaptation to sinewave gratings in a series of experiments investigating the effects of adapting time, adapting contrast, spatial frequency and retinal eccentricity. Contrast thresholds for vertical sinewave gratings truncated in space by a one-dimensional Gaussian envelope were measured before and after adaptation to a f...

Abstract Aiming at the current mainstream flying anchor payload for space debris removal, a solid thruster was proposed as separation driving force, and complete dynamic model of spacecraft platform were established. The effects gap between directional button tube, thrust eccentricity initial attitude on target accuracy under studied. analysis results showed that main factor affecting payload. ...
