BACKGROUND Humans spontaneously mimic the facial expressions of others, facilitating social interaction. This mimicking behavior may be impaired in individuals with Parkinson's disease, for whom the loss of facial movements is a clinical feature. OBJECTIVE To assess the presence of facial mimicry in patients with Parkinson's disease. METHOD Twenty-seven non-depressed patients with idiopathi...

This thesis examines the provision of on-demand multimedia streaming services using clusters of commodity PCs. In the proposed HammerHead multimedia server cluster architecture, a dynamic content replication policy is used to assign non-disjoint subsets of the presentations in a multimedia archive to cluster nodes. Replicas of selected presentations can be created on more than one node to achie...

This study investigated how spacing and massing affected the extent to which photographs of paintings are favoured. In this study, 50 individuals participated in one two conditions. We used a survey conduct experiment. survey, images were displayed groups six on web page. One massed set presented by artist. The other spaced paintings, each different artist, shown directly after another. All set...

in this paper by use of mathematical modeling of an observer [14,15] the notion of relative information functional for relative dynamical systemson compact metric spaces is presented. we extract the information function ofan ergodic dynamical system (x,t) from the relative information of t fromthe view point of observer χx, where x denotes the base space of the system.we also generalize the inv...
