Afonso d’Escragnolle Taunay, diretor do museu entre 1917 e 1945, ao montar as salas expositivas dedicadas as moncoes – expedicoes fluviais durante o seculo XVIII e inicios do seculo XIX –, acabou nao so por obscurecer eventos da expedicao Langsdorff retratados pelos ilustradores, como tambem contribuiu para uma discutivel associacao entre moncoes e bandeirantes – expedicoes de exploracao colonial durante o seculo XVII-XVIII –, cujos movimentos eram distintos em termos de personagens, roteiros e objetivos. Esta associacao e uma hipotese que tem sido levantada por varios autores, nomeadamente para o caso da exposicao inaugurada em 1929 no Museu Paulista. No entanto, este artigo perspetiva uma visao de conjunto, examinando a representacao das moncoes durante a direcao de Afonso d’Escragnolle Taunay nos dois museus, em particular as duas exposicoes no Museu Paulista dedicadas as moncoes – A-9 (1929) e B-4 (1944) – e no Museu Republicano Convencao de Itu a azulejaria na entrada deste museu. Nos tres casos analisa-se a forma como as obras de ilustradores do seculo XIX, nomeadamente as de Hercule Florence (1804-1879) e de Aime-Adrien Taunay (1803-1828), foram apropriadas, e em que contexto, para a representacao das moncoes, nomeadamente atraves da encomenda de pinturas e azulejos.","PeriodicalId":89440,"journal":{"name":"MIDAS journal","volume":"95 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83931419","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We introduce three additional capabilities, however, that we believe are especially important for research and development of CAI systems. The first is the ability to deploy components among different processes (as conventionally done) or within the same process (for optimal real-time performance), without requiring source-level modifications to the component. This is particularly relevant for real-time video processing, where the use of multiple processes could cause perceptible delays in the video stream. The second key feature is the ability to dynamically reconfigure the system. In a system composed of multiple processes on multiple computers, this allows one process to be restarted (e.g., after correcting a problem) and reconnected to the rest of the system, which is more convenient than restarting the entire distributed application and enables better fault recovery. The third key feature is the availability of run-time tools for data collection, interactive control, and introspection, and offline tools for data analysis and playback. The above features are provided by the open-source cisst software package, which forms the basis for the Surgical Assistant Workstation (SAW) framework. A complex computer-assisted intervention system for retinal microsurgery is presented as an example that relies on these features. This system integrates robotics, stereo microscopy, force sensing, and optical coherence tomography (OCT) imaging to transcend the current limitations of vitreoretinal surgery.","PeriodicalId":89440,"journal":{"name":"MIDAS journal","volume":"2011 ","pages":"2-9"},"PeriodicalIF":0.0,"publicationDate":"2011-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4167373/pdf/nihms370197.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"32685853","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
