Fontes visuais, cultura visual, história visual: balanço provisório, propostas cautelares

After a survey of contributions brought in by Art History, Visual Anthropology, Visual Sociology and Visual Culture Studies, concerning visual records and visual regimes, the author introduces a few prerequisites for a Visual History - intended not as a new academic feud, but as a set of strategic operational means of enhancing historical research in all its domains.
Early Stage Diagnosis of Parkinson’s Disease Using HOS Features of EEG Signals
Parkinson’s disease (PD) is a common neurodegenerative disease that causes involuntary muscle movements and tremor among other symptoms. One approach to diagnosing this disease is by analyzing the electroencephalography (EEG) signals of the patients. However, due to the complexity of this type of signal, more advanced feature extraction and classification methods are required. The goal of this study is to combine six well-known features in EEG analysis with eight higher order statistical features and use them for classification of early stage PD (1st and 2nd stage) from a healthy control group. After extracting the required features, eight classifiers are employed to classify the signals.
