Collaboration systems require an appropriate uurhorizarion model to specifL and winrain policies that iiut only facilitate group activities but also enforce restrictions and uccountubility. Existing models fail to incorporate adequately into authorization decisions the rich notion of context rhut is inherent to any collaborative setting. In this paper we present the Locale-based Access Control ...

Within the categoryW of archimedean lattice-ordered groups with weak order unit, we show that the objects of the form C (L), the set of continuous real-valued functions on a locale L, are precisely those which are divisible and complete with respect to a variant of uniform convergence, here termed indicated uniform convergence. We construct the corresponding completion of aW-object A purely alg...

If X is a locale then its valuation locale VX has for its points the valuations on X. V is the functor part of a strong monad on the category of locales, a localic analogue of the Giry monad. It is commutative, i.e. product valuations exist and a Fubini Theorem holds. An analogue of the Riesz Representation Theorem holds. Concrete representations are given for the tensor product of lattices and...

Deeply hidden in the artistic treasury of Northwest China, the Mogao Caves is a green land in yellow sand and a shining pearl on the Silk Road. But, thousands of years’ damages from the nature factors and artificial destroy and over-load tours cause diseases for all the caves in different extents. Consequently, the speed of painted statues and fresco degenerate dramatically. In order to protect...
