We present a method for segmenting the thalamus and its subnuclei from Diffusion Tensor Magnetic Resonance Images(DT-MRI) using coupled, region based, level sets in 3D. Each surface, formed from the zero’th level set of the level set function, is associated with the most representative tensor contained within the surface. All neighboring voxels are then assigned to a region by finding the surfa...

This study demonstrates that an integrated operator can benefit from cost savings, customer retention and prevention of revenue erosion by FMC migration strategy with introduction of advanced service packages. This development is driven by increasing importance of mobile network capabilities and services, as well as the lessening gap between fixed and mobile systems, in terms of technological m...

A method for finding correspondences between widely separated views is presented. The proposed solution consists in estimating the local perspective distortion between the neighborhoods of junctions. To this end, a formulation is proposed, based on a constrained minimization involving an estimated fundamental matrix. An application is also proposed to fundamental matrix recovery using crude cam...

We consider ghetto as a community of people ruled against their will by an external power. Members of the community feel that their laws are broken. However, attempts to leave ghetto makes their situation worse. We discuss the relation of the ghetto inhabitants to the ruling power in context of their needs, organized according to the Maslow hierarchy. Decisions how to satisfy successive needs a...

This first part of Chapter 5 covers the background to the development of reactive dyes, explains the history which led to their belated discovery and gives the reasons for their present importance. The nature of the dye-fiber bond is covered as well as the processes by which it is formed. The overall procedure for reactive batch dyeing, which involves the three steps of dyeing, fixation and was...

As has been widely discussed [1], the presence of extra dimensions may provide a possible explanation not only for the hierarchy problem of the fundamental interactions, but also for the late time cosmic acceleration, with no need to invoke either a cosmological constant Λ or a quintessence field Φ. In this paper we use a model independent formulation of the so-called brane-world program [2, 3]...

Huntebrinker's research was supported by the Deutsche Forschungsgemeinschaft. Let H 3 be three-dimensional hyperbolic space and a group of isometries of H 3 that acts discontinuously on H 3 and that has a fundamental domain of finite hyperbolic volume. The Laplace operator of H 3 gives rise to a positive, essentially selfadjoint operator on L2( nH 3). The nature of its discrete spectrum dspec i...

Schelling [1969, 1971a, 1971b, 1978] presented a microeconomic model showing how an integrated city could unravel to a rather segregated city, notwithstanding relatively mild assumptions concerning the individual agents' preferences, i.e., no agent preferring the resulting segregation. We examine the robustness of Schelling's model, focusing in particular on its driving force: the individual pr...

We study fluctuations in the drag force experienced by an object moving through a granular medium. The successive formation and collapse of jammed states give a stick-slip nature to the fluctuations which are periodic at small depths but become ”stepped” at large depths, a transition which we interpret as a consequence of the long-range nature of the force chains and the finite size of our expe...
