Un león de montaña (Felis concolor), macho de 23 años de edad Montaña desarrollo una claudicación crónica en el parque zoológico “El Pinar”, Caracas-Venezuela. Se le practico eutanasia. Macroscópicamente, la ...

Se compararon dos métodos de diagnóstico de Trichinellosis: triquinoscopía y digestión artificial. Se examinaron los músculos de 35 ratas Wistar infectadas per os con inóculos (10, 50, 100, 200, 300, 400, 500 larva...

Segmentation is often a critical step in image analysis. Microscope image components show great variability of shapes, sizes, intensities and textures. An inaccurate segmentation conditions the ulterior quantification a...

An updated edition of the classic book on computer architecture by J. L. Hennessy and D. A. Patterson. Authors show their high level standards for technological ideas, writing style, and teaching methodologies, all in o...

The use of evolutionary and swarm intelligence algorithms, has become a very popular option to solve complex real-world optimization problems. However, in their original versions, these algorithms lack a mechanism to han...

Providing Quality of Service (QoS) in Video on Demand systems (VoD) is a challenging problem. In this paper, we analyse the fault tolerance on a P2P multicast delivery scheme, called Patch Collaboration Manager / Multica...

For centuries, experimentation has been at the center of all successful scientific studies. Experimental explorations can offer new perceptions, weed out unproductive approaches and validate theories and practices. Compu...

Component Based Software Development (CBSD) relies upon utilization of previously developed software components OTS (Off-The-Shelf), which are appropriately merged to satisfy particular system requirements. However, wide...

In the first paragraph of the Introduction of the book the authors say "The definition of computer architecture has generated many discussions since the emergence of what could be considered the first computer in 1943, t...
