Address Event Representation (AER) approach to resistive sensor arrays
2020
Address event representation (AER) has become an excellent strategy when approaching traditional frame based applications, mainly vision sensors. In this paper, and Within this scope, the potential of the AER paradigm is demonstrated when considering resistive (non-vision) sensor arrays. For showing quantitative evidences, MOS AMS 0.35 μm versions of some of the circuit cells typically used in AER systems, such as Winner-Take-All (WTA) circuits, have been implemented and analyzed. In these unit-cells, basic resistance-controlled sources are considered as per sensing devices. Preliminary simulation results demonstrate that this approach is valid for a wide range of resistive sensors.
Frame-based and frameless endoscopic procedures in the third ventricle.
1997
Stereotactic guidance is useful for planning an accurate trajectory to the third ventricle. A guiding block with a ball joint was developed for frame-based endoscopy and adaptors for arm-based and armless navigation systems. Between 1992 and 1996, 52 patients were operated on endoscopically in the third ventricle under stereotactic guidance. Thirty-eight ventriculostomies, 13 biopsies and 10 cystic lesions were performed. The coordinates of two points were calculated; one in the foramen of Monro and the second in the third ventricle. The ventriculostomy was performed under endoscopic control bluntly with a Fogarty catheter in front of the basilar artery. Twenty-seven (71%) of the patients h…
Análisis de contenido de la representación del cuerpo en un libro de texto de Educación Preescolar
2012
La construccion social y cultural del cuerpo influye en el conocimiento personal y de los otros. Los libros de texto transmiten el capital cultural de una sociedad a sus ciudadanos mas pequenos. El objetivo del estudio consiste en describir la forma en que se representa el cuerpo en las imagenes de un libro de texto de educacion preescolar. Se realizo un analisis de contenido de las imagenes a traves de un codigo elaborado en estudios previos. Las ninas y ninos son representados con gran diferencia respecto a otros sectores poblacionales y se observo igualdad de presencia de mujeres y hombres independientemente de su edad. Con gran diferencia se representa un cuerpo entero vestido con ropa …
