purpose: to compare the outcomes of deep anterior lamellar keratoplasty (dalk) using the big-bubble technique with that of penetrating keratoplasty (pk) in patients with keratoconus. methods: this double-blind clinical trial included patients with moderate to advanced keratoconus and poor spectacle-corrected visual acuity or contact lens intolerance. refractive errors, best corrected visual acu...

In this paper, a computational intelligence method is used for the solution of fractional optimal control problems (FOCP)'s with equality and inequality constraints. According to the Ponteryagin minimum principle (PMP) for FOCP with fractional derivative in the Riemann- Liouville sense and by constructing a suitable error function, we define an unconstrained minimization problem. In the optimiz...

This deliverable specifies the traffic handling mechanisms for the second trial. Traffic handling in AQUILA is composed of four related mechanisms operating at different time scales: provisioning (days to weeks), resource pools (hours), admission control (seconds to minutes), traffic control (milliseconds). Keyword List: AQUILA, QoS, Internet, Traffic Control, Admission Control, MBAC, Provision...

This paper uses a 2D system setting in the form of repetitive process stability theory to design an iterative learning control law that is robust against model uncertainty. In iterative learning control the same finite duration operation, known as a trial over the trial length, is performed over and over again with resetting to the starting location once each is complete, or a stoppage at the e...
