Geophysical Investigations in the Old Panama Archaeological Site
(2006-06-28)
The results of geophysical prospections in an archaeological site of hispanic type in Panama (Central America) are presented in this article. The archaeological site of Old Panama has been intensively investigated with the ...
Seismic Response of Single-Degree-of-Freedom Systems with Structural Fuses
(2004-06-25)
Passive energy dissipation (PED) devices have been implemented to enhance structural performance by reducing seismically induced structural damage. In this article, metallic dampers are defined to be structural fuses (SF) ...
A Multiagent Based Strategy for Detecting Attacks in Databases in a Distributed Mode
(2009-07-01)
This paper presents a distributed hierarchical multiagent architecture for detecting SQL injection attacks against databases. It uses a novel strategy, which is supported by a Case-Based Reasoning mechanism, which provides ...
Tunable optical filters using compound ring resonators for DWDM
(07/28/2003)
The device is based on a loop mirror in a ring resonator. The loop mirror allows tuning by changing the coupling coefficient of a directional coupler. The loop mirror is implemented using a Sagnac configuration to have the ...
Adding extra sensitivity to the SMART non‐linear actuator using sensor fusion
(Industrial Robot: The International Journal Of Robotics Research And ApplicationIndustrial Robot: The International Journal Of Robotics Research And Application, 03/01/2004)
The prospect of using humanoid robots in practical applications attracts an important research effort and the latest steps forward in robot technology show many remarkable achievements where design aspects, control systems ...
Cuadro de mando integral para el diseño y validación de instrumentos para valorar el desempeño académico de docentes
(2009-12-22)
La valoración de la labor docente es un pilar de la acreditación universitaria. En un momento, particularmente sensible relacionado a esta tendencia global y a la imagen que emerge de las diferentes unidades académicas y ...
Scintillometer networks for calibration and validation of energy balance and soil moisture remote sensing algorithms
(05/07/2007)
Accurate estimation of sensible and latent heat fluxes as well as soil moisture from remotely sensed satellite images poses a great challenge. Yet, it is critical to face this challenge since the estimation of spatial and ...
Demultiplexers for ultranarrow channel spacing based on Mach-Zehnders and ring resonators
(09/01/2004)
Novel demultiplexer configurations based on concatenated Mach-Zehnders and a ring resonator are presented. These new devices exhibit high channel isolation, flexibility, no loss, and megahertz-adjustable full width at half ...
On the Design and Development of Climbing and Walking Robots for the Maritime Industries
(2005-06-27)
Modern robotic systems are increasingly powerful in terms of sensor fusion and mobility. Present technological progress allows advanced robots to cope progressively much better also with complex environments such as those ...
Estimation Aveugle Itérative par Filtrage H∞ des Décalages Doppler d’un Système OFDMA Entrelacé en Liaison Montante
(2009-07-01)
Il s'agit d'estimer et de compenser de multiples décalages Doppler dans un contexte multi-(porteuses, utilisateurs) OFDMA en liaison montante. Pour cela, nous proposons une architecture de réception itérative capable ...
