This paper considers the concept of presence in virtual environments with respect to a Situationist critique of spectacularised urban space. The aim is to explore the concepts of space and place that have become bound up with presence research from an alternative critical viewpoint. The adopted Situationist perspective distinguishes between representations of places and inhabitable spaces, high...

A design approach to low-vision device development-vision multiplexing-was introduced recently. This approach has been applied successfully to the design of novel electronic and optical low-vision aids. This paper discusses the application of the vision-multiplexing concept to spectacle lens design to address issues of low vision and to resolve problems of color discrimination and glare in driv...

Ptosis has usually been treated by surgery and the literature contains suggestions of over eighty different operations for its correction. Duke-Elder (I952) has pointed out that, in spite of the variety and ingenuity of remedial operations, the results are by no means invariably brilliant and in cases due to neuromuscular disease shortening of the lid is usually unsatisfactory. Apart from the c...

in this paper we get some results and applications for duals and approximate duals of g-frames in hilbert spaces. in particular, we consider the stability of duals and approximate duals under bounded operators and we study duals and approximate duals of g-frames in the direct sum of hilbert spaces. we also obtain some results for perturbations of approximate duals.
