In this paper we present R-DEVICE, a deductive rule language for reasoning about RDF metadata. R-DEVICE includes features such as normal and generalized path expressions, stratified negation, aggregate, grouping, and sorting, functions. The rule language supports a second-order syntax, where variables can range over classes and properties. Users can define views which are materialized and, opti...

This paper describes PalymSys -an extended version of the CLIPS language that is designed to facilitate the implementation of blackboard systems. The paper first describes the general characteristics of blackboards and shows how a control blackboard architecture can be used by AI systems to examine their own behavior and adapt to real-time problem-solving situations by striking a balance betwee...

Film clips are an important tool for evoking emotional responses in the laboratory. When compared with other emotionally potent visual stimuli (e.g., pictures), film clips seem to be more effective in eliciting emotions for longer periods of time at both the subjective and physiological levels. The main objective of the present study was to develop a new database of affective film clips without...

Suicide attempt linked to breakdown he Golgi apparatus breaks down temporarily to segregate into daughter cells during mitosis, but during apoptosis the organelle fragments irreversibly.

Fatigue crack growth in different panels, made of AA6156 T6, was investigated experimentally and numerically. Three types panels were used, simple one, so-called base metal (BM), panel with 4 welded stringers 3 clips. Experimental investigation indicated benefits stringers, especially respect to residual life, since the number cycles more than doubled (420 Kcyc vs 195 for initial length 14 mm),...
