La aparición de la teoría de las revoluciones científicas de Thomas S. Kuhn supuso una intensa alteración para la didáctica de las ideas del pensamiento de las ciencias —entre ellas, la geografía—; desde entonces éste se presenta como una sucesión…

The chemical effects of acoustic cavitation are obtained in sono-reactors built-up from a vessel and an ultrasonic
source. In this paper, simulations of an existing sono-reactor are carried out, using a linear acoustics model, accounting
for the vibrations of the…

En este artículo ofrecemos algunas ideas sobre la actividad científica, en Venezuela. En la evolución de la cultura y comunidad académica en Venezuela durante la primera década de gobierno de la revolución bolivariana socialista (1998-2008) nos hemos propuesto llenar lo…

We develop a qualitative method for understanding and representing phase space structures of complex systems and demonstrate the method with a program, MAPS --- Modeler and Analyzer for Phase Spaces, using deep domain knowledge of dynamical system theory. Given a…

Automated Program Analysis is the process of discovering decompositions of a system into sub-units such that the behavior of the whole program can be inferred from the behavior of its parts. Analysis can be employed to increase the explanatory power…

Consider a world of 'objects.' Our goal is to place these objects into categories that are useful to the observer using sensory data. One criterion for utility is that the categories allow the observer to infer the object's potential behaviors,…

There has been a long-standing desire in computer science for a way of collecting and using libraries of standard software components. The limited success in actually doing this stems not from any resistance to the idea, nor from any lack…

We wish to design a diagnostic for a device from knowledge of its structure and function. the diagnostic should achieve both coverage of the faults that can occur in the device, and should strive to achieve specificity in its diagnosis…

La hemoncosis, causada por el nematodo del abomaso de rumiantes Haernonchus contortus, constituye una de las enfermedades parasitarias más notables del ganado ovino en todo el mundo. Las infecciones provocan síndromes anémicos y de mala digestión/absorción que pueden causar la…
