Scenario analysis as a decision-support tool: a maritime patrol case study Inproceedings André Negrão Costa; Rafael Lemos Paes; Marcelo Zawadzki; Diego Geraldo Resumo | Links | BibTeX | Tags: Maritime, optimization, Scenario analysis @inproceedings{Andr\'{e}2015Scenariob, This article argues for the use of scenario analysis as a decision-support tool, regarding incentives and investments on either the development or the acquisition of new military systems. In particular, it presents a study on the maritime patrol operations scenario with the availability of synthetic aperture radar satellite images during its planning process. Through a proper analysis, the images may serve as a powerful subsidy for enhancing mission effectiveness and reducing costs. The effectiveness may be measured by the number of encountered vessels and the cost reductions may come from the fewer flight hours necessary for the mission through path optimization. As a conclusion, not only it is possible to observe clear improvements on the mission success, but also the potential this kind of analysis has for force sizing and capacity development. |

Compressão de imagens utilizando o padrão H.264 Inproceedings Paulo Henrique F T Soares; Rafael Lemos Paes; Marcelo Silva Pinho Resumo | Links | BibTeX | Tags: compression, H264, optimization @inproceedings{Paulo2011H264b, The H.264 video coding standard is used from applications which high definition is required, such as at Blue-Rays, to lower bit rate uses, like video conference. Its intra prediction out- performs any image compression standard, but the price is the computer complexity. In this paper, it will be described briefly a way to achieve a good rate compression for images without demanding too much of a processor. |
