We investigate algorithmic properties of infinite transition graphs that are generated by rewriting systems over unranked trees. Two kinds of such rewriting systems are studied. ...
— The use of a manageable optical network is an important requirement for the new advanced data-intensive grid applications that begin to emerge on the e-Science field. In this ...
A new model for representing temporal access control policies is introduced. In this model, temporal authorizations are represented by time attributes associated with subjects and...
