This paper presents a vision-based robot homing method capable to deal with a series of dynamic changes in the environment. First we build a robust and stable representation of the goal location using scale invariant features (SIFT) as visual landmarks of the scene, followed by a matching and a voting scheme. We end up with a description that contains the(More)
BACKGROUND AND AIM Several biological and epidemiological studies support a relationship between smoking and Helicobacter pylori (H. pylori) to increase the risk of pathology. However, there have been few studies on the potential synergistic association between specific cagA and vacA virulence factors and smoking in patients infected by Helicobacter pylori.(More)
INTRODUCTION The behavior disorder occurring during REM (Rapid Eye Movement) sleep is a parasomnia characterized by absence of atonia typical of this phase of sleep, although the other characteristics are maintained, namely rapid eye movements and desynchronization of cortical electrical activity. Clinically it is accompanied by abrupt, often violent(More)
ACCOMPANY Deliverable 2.4 Implementation and integration of context-aware planner for empathic behavior generation. This deliverable reports the on the work outcomes for T2.4 comprising a brief literature review on context-aware systems and human-robot proxemics and the requirements for developing a context-aware planner suitable for empathic behaviour(More)
A model has been developed to provide an UPnP communication implementation that reduces QoS negotiation delay. The proposed model extends the UPnP QoS Architecture standard by adding status information about the network topology and the established traffic flows. The introduced extensions are compatible to the existing UPnP standard. The implementation has(More)
INTRODUCTION Stroke is one of the main causes of morbidity and mortality in developed countries today. Smoking is a risk factor that is associated with arteriosclerotic disease. AIM To evaluate the risk of having a stroke associated to both active and passive smoking in a case-control study. PATIENTS AND METHODS A case-control study was conducted which(More)
INTRODUCTION Infantil progressive polydystrophy was described by Alpers in a child with psychomotor retardation, crises which were resistant to treatment and diffuse loss of cortical neurons. OBJECTIVE The aim of this study was to review the neurophysiological aspects of Alpers syndrome and their clinical correlation. MATERIAL AND METHODS We present(More)
INTRODUCTION The Proteus Syndrome was defined in 1983 by Wiedeman. However, the first case mentioned in the literature was that of Joseph Merrick, the Elephant Man, presented by Sir Frederick Treves in 1884. It is a rare pathological condition. Its multiple clinical features include; partial gigantism of hands and/or feet, pigmented nevi, hemihypertrophy of(More)
