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)
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)
Deafness brings consequences to deaf people's life as well as to their families, who usually has its dynamic changed in the struggle to adapt to the new needs and demands. In this sense, the families not only use their internal resources, but also, they look for help and support out of their group, in their social network. The goal of this paper is to(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)
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)
BACKGROUND It has been demonstrated that a new reconstruction algorithm for myocardium perfusion imaging (MPI) allows faster acquisition with similar accuracy. The prognostic value of MPI performed with this software and short acquisition time is unknown. METHODS To determine the prognostic value we followed 3184 consecutive MPI patients between March(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)
OBJECTIVE To investigate, in patients with known or suspected coronary artery disease (CAD) undergoing myocardial perfusion single-photon emission computed tomography (MPS),the interaction between patient symptoms and single-photon emission computed tomography (SPECT) results, and their effects on patient outcomes. Previous data have shown that medical(More)
A misconception regarding the human metabolism has been shown to be widespread among high school students. The students consider glucose as the sole metabolic fuel, disregarding that lipids and amino acids can be oxidized for ATP production by human cells. This misconception seems to be a consequence of formal teaching in grade and high schools. The present(More)
