Human interfaces for computer graphics systems are now evolving towards a total multi-modal approach. Information gathered using visual, audio and motion capture systems are now becoming increasingly important within user-controlled virtual environments. This paper discusses real-time interaction through the visual analysis of human face feature. The underlying approach to recognize and analyze...

The present research explores the relationship between the two components of autobiographical memory--episodic and semantic self-knowledge--and identity strength in older adults living in the community and residential care. Participants (N= 32) completed the autobiographical memory interview and measures of personal identity strength and multiple group memberships. Contrary to previous research...

What do we mean when we say action is possible in disequilibrium? If we adopt Hayek's approach to equilibrium, we must mean that we can act in a world where the plans that motivate and define those actions are not mutually compatible. This is hardly controversial. After all, the market process features rivalrous actions, that is, actions that are part of mutually inconsistent plans. Successful ...

Human interfaces for computer graphics systems are now evolving towards multi-modal approach. Information gathered using visual, audio and motion capture systems are now becoming increasingly important within user-controlled virtual environments. This paper discusses real-time interaction with virtual world through the visual analysis of human facial features from video. The underlying approach...

Criteria to design MR (Magnetic Resonance) compatible mechatronic devices, e.g., surgical robots, are discussed. Some of critical interactions between MRI and mechatronic devices are discussed. Experimental results of the effects from several passive and active mechanical elements are demonstrated. Some passive elements, e.g., ball screw and linear guide have point contacts therefore, they are ...

OBJECTIVE To study the frequency of positive serology for celiac disease (CD) in patients with duodenal biopsies suggestive of this disease. MATERIAL AND METHODS Cross sectional study. We included patients with duodenal biopsies histologically compatible with CD and antigliadin, antiendomysial and IgA antitransglutaminase antibodies. We defined a "case" of CD if there was a positive biopsy an...

Multiplicity-free actions are symplectic manifolds with a very high degree of symmetry. Delzant 2] showed that all compact multiplicity-free torus actions admit compatible KK ahler structures, and are therefore toric varieties. In this note we show that Delzant's result does not generalize to the non-abelian case. Our examples are constructed by applying U (2)-equivariant symplectic surgery to ...
