—Existing works for semantic trajectory data analysis have focused on the intersection of trajectories with application important geographic information and the use of the speed to find interesting places. In this paper we present a novel approach to find interesting places in trajectories, considering the variation of the direction as the main aspect. The(More)
Chagas disease (CD), caused by Trypanosoma cruzi, affects approximately eight million individuals in Latin America and is emerging in nonendemic areas due to the globalisation of immigration and nonvectorial transmission routes. Although CD represents an important public health problem, resulting in high morbidity and considerable mortality rates, few(More)
Parkinson's disease (PD) is an incurable progressive neurodegenerative disorder. Clinical presentation of PD stems largely from the loss of dopaminergic neurons in the nigrostriatal dopaminergic pathway, motivating experimental strategies of replacement based on cell therapy. Transplantation of dopaminergic neurons derived from embryonic stem cells(More)
Enormous quantities of trajectory data are collected from many sources, as GPS devices and mobile phones, as sequences of points. These data can be used in many application domains such as traffic management, urban planing, tourism, and bird migration. However, in most applications a higher level of abstraction should be used instead of sample points. In(More)
Chagas disease is caused by infection with the intracellular protozoan parasite Trypanosoma cruzi. At present, nifurtimox and benznidazole, both compounds developed empirically over four decades ago, represent the chemotherapeutic arsenal for treating this highly neglected disease. However, both drugs present variable efficacy depending on the geographical(More)
Aromatic diamidines have been successfully used to combat a wide range of parasites that cause important human infections. Recently we reported that a N-phenyl-substituted analogue of furamidine (DB569) exerts a micromolar trypanocidal activity against Trypanosoma cruzi in vitro. Since DB569 also reduces the cardiac parasitism and increases the survival(More)
Trajectory data play a fundamental role to an increasing number of applications, such as traffic control, transportation management, animal migration, and tourism. These data are normally available as sample points. However, for many applications, meaningful patterns cannot be extracted from sample points without considering the background geographic(More)
—Real-time digital simulators (RTDS) are used for real-time simulation of power systems. As the complexity of the electric power grid and associated control increases in the future, modeling and simulation of the power network as well as the control becomes essential. This requirement will be even more prominent in the context of smart grid. As enabling(More)
T he unprecedented availability of data promised by linked data 1 on the Web represents a major paradigm shift over the existing Web's structure. By building on Web infrastructure (URIs and HTTP), Semantic Web standards (such as the Resource Description Framework and RDF Schema [RDFS]), and vocabularies, linked data can effectively reduce barriers to data(More)
