In this paper we present several efficient computational procedures for defeasible reasoning while the plausible and well-defined semantics, viz. preferred models and stable mode...
0-stable 0-categorical linked quaternionic mappings are studied and are shown to correspond (in some sense) to special groups which are 0stable, 0-categorical, satisfy AP(3) and ha...
Databases may not satisfy integrity constraints (ICs) for several reasons. Nevertheless, in most of the cases an important part of the data is still consistent wrt certain desired...
Abstract. A longstanding open problem is whether there exists a nonsyntactical model of the untyped -calculus whose theory is exactly the least -theory . In this paper we investiga...
In this paper the control of exible joint manipulators is studied in detail. A composite control algorithm is proposed for the exible joint robots, which consists of two main part...
