We present a set of algorithms for simulating and visualizing real-time crowds in GPU (Graphics Processing Units) clusters. First we present crowd simulation and rendering techniques that take advantage of single GPU machines. Then, using as an example a wandering crowd behavior simulation algorithm, we explain how this kind of algorithms can be extended for their use in GPU cluster environment...

In this paper we present a methodology for blind source separation (BSS) based on a coherence function to solve the problem of linear instantaneous mixtures of signals. The proposed methodology consists of minimizing the coherence function using a heuristic algorithm based on the simulating annealing method. Also, we derived an analytical expression of the coherence for the BSS model, in which ...

Kasai K, Salamon-Murayama N, Levrier O, et al. Theoraetical situation of brain white matter tracts evaluated by three-dimensional MRI. Surg Radiol Anat 1996;18: 295–302 The location and course of the white matter tracts in the cerebrum are described and shown by means of diagrams in Tailarach space. If you want to understand the location and course of the major and the obscure white matter trac...

Ferlito A, Devaney KO, Rinaldo A, et al. Ear cholesteatoma versus cholesterol granuloma. Ann Otol Rhinol Laryngol 1997;106:79–85 This is an excellent histopathology-based review (no images) that defines and differentiates these two entities. Very interesting information. Authors reiterate that cholesteatoma is a misnomer: it is not a neoplasm (-oma), there are no cholesterol crystals (chole-), ...

Zumkeller M, Behrmann R, Heissler HE, Dietz H. Computed tomographic criteria and survival rate for patients with acute subdural hematoma. Neurosurgery 1996;39: 708–713 Among 174 patients with acute subdural hematomas, hematoma thickness exceeding 18 mm was associated with survival rates that progressively fell below 50%. A 50% survival rate was reached when the midline shift reached 50%, and su...
