Calibración de modelos de elementos finitos de muros de adobe por optimización : Using optimisation for calibrating finite element models for adobe walls
(2009-06-02)
This paper presents a proposal for applying optimisation schemes to calibrating 3D linear and non-linear finite element models for analysing structural walls made out of adobe. The calibration was based on laboratory data ...

Effect of magnetic field on off-axis donor binding energy in a nanotube
(2006-04-05)
We analyze the effect of the mixing of the low-lying s and px, y subbands on the ground-state binding
energy of the off-axis donors in cylindrical nanotubes in the presence of a magnetic field parallel to the
axis. We ...
Hinf controller design for a variable wind speed turbine
(2008-10-10)
Abstract: This paper gives a description of a wind
generator system composed by a doubly fed induction
generator (DFIG), its dynamic model and each one of its
subsystems. Also, the control logic that regulates the
active ...
The construction of a prototype of a 5OMBS free space laser optic transmitter
(2004-10-21)
Light emitting diodes or LEDs, which are special for telecommunications, and laser diodes were characterized. A free
space optical data transmitter and its corresponding receptor were built. A power of 10mW semiconducting
laser ...
Caracterización fisicoquímica y morfológica de asfaltos modificados con material reciclado : Physicochemical and Micromorphological Evaluation of Asphalt Modified with Recycled Materials
(2008-10-21)
For more than 30 years, modified asphalt obtained by adding elastomer and plastomer type polymers has been used in flexible pavements.However, the high cost of modifiers has prevented their use from becoming
popular; ...
Design and test of nonlinear Class-E and Class-F RF power amplifiers
(2009-10-30)
RF power amplifiers of high efficiency and low
consume are very important for applications where the size
of the device is important, such as mobile phones, network
sensors or PDAs. The classical operation modes as ...
