The present paper describes the design of a hybrid actuation control concept, a fuzzy logic proportional-integral-derivative plus a conventional on-off controller, for a new morphing mechanism using smart materials as actuators, which were made from shape memory alloys (SMA). The research work described here was developed for the open loop phase of a morphing wing system, whose primary goal was...

Magnetic instruments such as cross-wing gradiometers, vertical gradiometers and full tensor SQUID magnetometers presented challenges for geological interpretation and geophysical inversion. In particular, the full tensor magnetometer presents many new challenges for an interpreter where only the vertical derivative of the vertical magnetic component presents a useful geological analogue for vis...

In the current bandwidth market, Internet Service Providers (ISPs) provide guaranteed Internet bandwidth within their domains. However, they are incapable of providing such assurances for data crossing their domain boundaries. In this paper, we present a spot pricing scheme for Internet bandwidth contracts within an ISP domain. These models when implemented at access or exchange points of diffe...

An n-crossing projection of a link L is onto plane such that n points on are superimposed top each other at every crossing. We prove for all k?? and links L, the inequality c2k+1(L)?2g(L)+r(L)?1k2 holds, where c2k+1(L), g(L) r(L) (2k+1)-crossing number, 3-genus, number components respectively. This result used to new bound odd crossing numbers torus knots generalizes Jablonowski (see [M. Jab?on...

Singularly perturbed delay differential equations arising from the regularization of state dependent neutral delay equations are considered. Much insight into the solution of the regularized problem and into its limit for ε→ 0+ is obtained by the study of asymptotic expansions. Due to discontinuities in the derivative of the solution of the neutral delay equation and the presence of different t...

We studied the relation between vertical eye movements and binocular torsion in five subjects with dissociated vertical deviation (DVD). During trials, subject viewed a well illuminated Snellen letter chart, with both eyes uncovered during 4 seconds, Subsequently, DVD was induced by covering one eye during 4 seconds. Finally, both eyes were uncovered during 4 seconds. Several trials were record...
