The inertia of an n × n matrix A is defined as the triple (i+(A), i−(A), i0(A)), where i+(A), i−(A), and i0(A) are the number of eigenvalues of A, counting multiplicities, w...
We consider coverage problems in sensor networks of stationary nodes with minimal geometric data. In particular, there are no coordinates and no localization of nodes. We introduc...
Abstract. In this paper we present a novel approach for the predicative specification of user rights in the context of an object oriented use case driven development process. We e...
Simplification has been long recognised to be a fundamental problem within computer algebra[17]. However, even for the class of elementary functions, it has not been resolved in ...

In this paper we present a volume data model amenable to querying volumes in databases. Unlike most existing volume models, which are directed towards specific applications (notab...
