Complexity

Por • 10 oct, 2011 • Category: sociologia

The term complexity derives etymologically from the Latin plexus, which means interwoven. Intuitively, this implies that something complex is composed by elements that are difficult to separate. This difficulty arises from the relevant interactions that take place between components. This lack of separability is at odds with the classical scientific method – which has been used since the times of Galileo, Newton, Descartes, and Laplace – and has also influenced philosophy and engineering. In recent decades, the scientific study of complexity and complex systems has proposed a paradigm shift in science and philosophy, proposing novel methods that take into account relevant interactions.



Education for Computational Science and Engineering

Por • 24 ago, 2011 • Category: Educacion

Computational science and engineering (CSE) has been misunderstood to advance with the construction of enormous computers. To the contrary, the historical record demonstrates that innovations in CSE come from improvements to the mathematics embodied by computer programs. Whether scientists and engineers become inventors who make these breakthroughs depends on circumstances and the interdisciplinary extent of their educations. The USA currently has the largest CSE professorate, but the data suggest this prominence is ephemeral.



Bases de datos de venezolanos en manos cubanas

En 2005, la UCI creó lo que denomina su “cara comercial”, la empresa Albet Ingeniería y Sistemas S. A., que vende los servicios y productos de la universidad cubana. “Sus resultados en la exportación la ubican como una de las principales empresas de su sector en el país, con una destacada participación en el Convenio de Cooperación Integral Cuba-Venezuela y con grandes perspectivas de crecimiento en su proyección internacional”, afirma la compañía en su sitio web. De acuerdo con documentos que la UCI ha presentado en eventos internacionales, Albet esperaba facturar 174 millones de dólares en 2009 y proyecta ganancias de 252,3 millones de dólares en 2010. Las facturas se pagan con petróleo venezolano.

For decades, CSE has been misunderstood to require massive computers, whereas breakthroughs in CSE have historically been the mathematical programs of computing rather than the machines themselves.



PDVSA ha dispuesto más de 83 mil millones de dólares al sector social

Por • 18 feb, 2011 • Category: Nacionales

Los gobernantes de la vieja Pdvsa a través de la firma de convenios de asociaciones estratégicas de la Faja Petrolífera del Orinoco, se entregaron a estas empresas más de 600 mil barriles de producción de la Faja. “Se estableció la regalía de 1%, un impuesto no petrolero de 34%, además de que Pdvsa no podía tener la participación mayoritaria en ninguno de estos proyectos”.



Evolutionary Mechanics: new engineering principles for the emergence of flexibility in a dynamic and uncertain world

Por • 7 feb, 2011 • Category: Ciencia y tecnología

Engineered systems are designed to deftly operate under predetermined conditions yet are notoriously fragile when unexpected perturbations arise. In contrast, biological systems operate in a highly flexible manner; learn quickly adequate responses to novel conditions, and evolve new routines/traits to remain competitive under persistent environmental change.



The Fantastical Promise of Reversible Computing

Reversible logic could cut the energy wasted by computers to zero. But significant challenges lie ahead



Physicist Discovers How To Make Quantum Foam In A Test Tube

Por • 29 ene, 2011 • Category: Leyes

That’s handy because it allows engineers to recreate all kinds of exotic astrophysical objects in the lab. We’ve already talked about the first black hole made using a metamaterial and seen how it ought to be possible to recreate the Big Bang and even entire multiverses.



White Holes And Kitchen Sinks

Scientist have long believed that it is possible to create a white hole in your kitchen sink. Now they’ve proved it experimentally.



Nuevas antenas de nanotubos de carbono revolucionan la captación de energía solar

Por • 12 oct, 2010 • Category: Ciencia y tecnología

Ingenieros químicos del Massachusetts Institute of Technology (MIT) han desarrollado una nueva metodología de captación de energía solar, que sería mucho más eficaz que las células o paneles tradicionales.
