Using geographical information systems for management of back-pain data

This is the post-print version of the Article. The official published version can be accessed from the link below - Copyright @ 2002 MCB UP LtdIn the medical world, statistical visualisation has largely been confined to the realm of relatively simple geographical applications. This remains the case, even though hospitals have been collecting spatial data relating to patients. In particular, hospitals have a wealth of back pain information, which includes pain drawings, usually detailing the spatial distribution and type of pain suffered by back-pain patients. Proposes several technological solutions, which permit data within back-pain datasets to be digitally linked to the pain drawings in order to provide methods of computer-based data management and analysis. In particular, proposes the use of geographical information systems (GIS), up till now a tool used mainly in the geographic and cartographic domains, to provide novel and powerful ways of visualising and managing back-pain data. A comparative evaluation of the proposed solutions shows that, although adding complexity and cost, the GIS-based solution is the one most appropriate for visualisation and analysis of back-pain datasets

Desenvolvimento e utilização de um simulador de chuvas para estudos de atributos físicos e químicos do solo relacionados a impactos ambientais.

Estudos sobre o efeito das chuvas em atributos do solo são difíceis de serem realizados com chuva natural, pois não se tem controle sobre a duração , intensidade, distribuição e tipo de chuva. Uma alternativa que se apresenta é a utilização de simuladores de chuvas que permitem controlar as características das mesmas e têm a vantagem de poderem ser utilizados a qualquer tempo. Este tipo de equipamento já vem sendo utilizado em estudos de manejo de solos há bastante tempo. Já foram construídos vários modelos e atualmente existem alguns totalmente controlados por computador. No caso presente utilizou-se o princípio de funcionamento do simulador descrito por Meyer & Harmon (1979), simplificando?se o sistema de funcionamento, que era elétrico, para um sistema mecânico.bitstream/item/12266/1/documentos_37.pd

Phase-space reconstruction of an atomic chaotic system

We consider the dynamics of a single atom submitted to periodic pulses of a far-detuned standing wave generated by a high-finesse optical cavity, which is an atomic version of the well-known ``kicked rotor''. We show that the classical phase-space map can be ``reconstructed'' by monitoring the transmission of the cavity. We also studied the effect of spontaneous emission on the reconstruction, and put limits to the maximum acceptable spontaneous emission rate.Comment: 5 figures, submitted to PR
