In this paper we describe a tangible user interface “Tangible Tiles”, which utilizes optically tracked transparent Plexiglass tiles for interaction and display of projected im...
Abstract. A competition between systems for doing exact real number computations was held in September 2000. We present the results obtained and give a short evaluation of the di...
This paper presents a novel local image descriptor that is robust to general image deformations. A limitation with traditional image descriptors is that they use a single support ...
For sums of radicals Pk i=1 i di p i, where i; i are elements of some real algebraic number eld Q( ); di p i 2 R; we present a deterministic polynomial time algorithm to decide wh...
Let β be a real number with 1 < β < 2. We prove that the language of the β-shift is ∆0 n iff β is a ∆n-real. The special case where n is 1 is the independently inter...
