RESUMO: O presente artigo tem como objetivo apresentar um relato sobre os estudos e as experiências de práticas artísticas no Grupo de Estudos Estúdio de Pintura Apotheke utilizando possibilidades de técnicas de impressão que convergem para um campo expandido experimental da poética do artista/pesquisador. Nesse sentido, relatam-se principalmente duas experiências, sendo a primeira a técnica de monotipia a óleo, originada por Castiglione em 1648, tendo como referência o artista Kahn (2013) e Meyer (2006). A segunda, a técnica de cianotipia, uma reprodução artística pela fórmula de sais de ferro descoberta por Herschel em 1842. Como fio condutor, utilizo-me de minhas próprias obras, reconfigurado-as como experiências pessoais para meu aprendizado e conhecimento.
Abstract. Non gaussian sources of erros need to be taken into consideration when searching for planetary transits. Such phenomena are mostly caused by the impact of high energetic particles on the detector (Pinheiro da Silva et al. 2008). The detection efficiency of transits, therefor, depend significantly on the data quality and the algorithms utilized to deal with these errors sources. In this work we show that a modified detrend algorithm CDA (CoRoT Detrend Algorithm; Mislis et al. 2010) using a robust statistics and an empirical fit, instead of a polynomial one, can eliminate more efficiently gaps in the data and other long-term trends from the light-curve. Using this algorithm enables us to obtain a reconstructed light-curve with better signal-to-noise ratio that allows to improve the detection of exoplanet transits, although long term signals are destroyed. The results show that these modifications lead to an improved BLS (Box-fitting Least Squares; Kovács, Zucker & Mazeh 2002) algorithm spectrum. At the end we have compared our planetary search results with CoRoT (Convection, Rotation and planetary Transits) satellite chromatic light-curves available in the literature.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
