There are rare reports of young women with moyamoya disease associated with Graves' disease; we are unaware of any previous reports of this association in prepubescent girls. We report a 10-year-old girl who presented with multiple bilateral strokes. Cerebral angiography demonstrated moderate to severe stenosis of her bilateral distal internal carotid(More)
An efficient numerical bifurcation and continuation method for the Navier–Stokes equations in cylindrical geometries is presented and applied to a nontrivial fluid dynamics problem, the flow in a cylindrical container driven by differential rotation. The large systems that result from discretizing the Navier–Stokes equations, especially in regimes where(More)
In this paper, an echo canceller is presented, using an adaptive filter with a modified LMS (Least Mean Square) algorithm, where this modification is achieved coding error on conventional LMS algorithm. Simulation results, show a better convergence speed than conventional LMS algorithm, furthermore, Coded Error algorithm presents less complexity for digital(More)
In disaster situations, where ad hoc mobile networks are normally used, the location and quantity of existing obstacles is random. Most existing mobility models have not been developed with consideration of the obstacles that exist in a disaster environment. This paper proposes two methods of mobility that realistically represent movement in an environment(More)
In this paper it is described an adaptive method for Heart Rate Variability (HRV) signal filtering, which uses a noise canceller structure formed by a Finite Impulse Response (FIR) filter together with the Least Mean Squares (LMS) adaptation algorithm in order to reduce respiration influence on HRV information. Respiration and electrocardiogram (ECG)(More)
