We introduce a typed variant of Safe Ambients, named Secure Safe Ambients (SSA), whose type system allows behavioral invariants of ambients to be expressed and verified. The most ...
Geographical information systems are more and more based on a DBMS with spatial extensions, which is also the case for the system described in this paper. The design and implementa...
We study the accuracy of data on some local topographic attributes derived from digital elevation models (DEMs). First, we carry out a test for the precision of four methods for ca...
