We consider waves propagating through multiscale media. Much is known about waves propagating through a medium that satisfies a scale separation assumption with random fluctuations on a microscale. Here we go beyond this situation and consider waves propagating through a medium defined in terms of a long range process. Such a medium can for instance be modeled in terms of a one-dimensional frac...

INTRODUCTION Prospective motion correction using an external tracking device is an effective technique for motion correction in fMRI [1]. It has advantages over image-based correction methods [2], which require full volume coverage to compute motion parameters in a full six degrees of freedom (6DOF). The ultimate goal of this project is to use prospective correction to perform fMRI experiments ...

In this paper we analyze the dynamic stability of the hovering magnetic top from first principles without using any preliminary assumptions. We write down the equations of motion for all six degrees of freedom and solve them analytically around the equilibrium solution. Using this solution we then find conditions which the height of the hovering top above the base, its total mass, and its spinn...

A typical shadow-eliminating algorithm is presented in this paper. Algorithms for vehicle detection, edge detection and shadow detection are also given. If the shadow is not separated from the vehicle, the next traffic control processes, like vehicle classification, tracking and speed calculation, will be rather difficult. Our approach for shadow processing runs in real time in low-cost hardwar...

The influence of separation from dam on suckling behavior of lambs was tested from day 5 after lambing until the lambs were 8 days old. The twelve ewes with their lambs were randomly assigned in equal numbers to two treatments; separating from dam (S) and non-separating without suckling (NS). Separation from dam resulted in lower duration and higher frequency of suckling. The lambs in S treatme...

To extract the platinum group metals from the ore, and to refine them to the very high purity required for their many applications, requires a multitude of complex operations. A t present the final re.fining stage that produces the individual platinum group metals is carried out by selective precipitation from a solution of mixed platinum group metals, but this is inefficient as far as the degr...

The RoboCup Rescue competition aims at boosting research in robots and infrastructure able to help in real rescue missions. The task is to find and report victims in areas of different grades of roughness, which are currently indoor. It challenges to some extreme the mobility of robot platforms as well as the autonomy of their control and sensor interpretation software. In the 2004 competition,...

Research in 3-D object tracking is typified by approaches which attempt to recover the six degrees of freedom of an object in each frame, e.g., [ l l , 14, 6 , 171. Once a correspondence between image and model features is determined, changes in the positions of image features in successive frames is used to update the pose of the object. Although providing accurate pose of the object at each f...
