The paper presents an approach to specify in an integrated way by visual , diagrammatic languages the structural and behavioural aspects of database applications. Hereby, well-known extended Entity-Relationship diagrams are employed to specify the structural aspects. The behavioural aspects of a database application are speciied by using ViAL (Visual Action Language). ViAL speciications are a s...

The self-assembly of sphere-forming triblock copolymers confined between two thin homogeneous surfaces is investigated based on mean-field dynamic density functional theory. The morphologies deviating from the bulk sphere-forming phase are revealed, including cylinders oriented perpendicular to the surface, cylinders oriented parallel to the surface, perforated lamellae and lamellae by varying ...

Global systems – systems which may operate over transient networks including mobile elements and in which computation itself may be mobile – are gaining in importance. Nevertheless, the means for their modelling are still underdeveloped. The Unified Modelling Language (UML) is well developed for convenient modelling of behavior, but is not yet so useful for modelling aspects of design relevant ...

In contrast to the conventional methodology of object-oriented program design focused on the interaction of objects, object-oriented database design should be based on the representation of objects. We put more emphasis in the application semantics pertinent to the structures of, relationships between, and constraints on objects than operations on the objects. Enhanced Entity-Relationship (EER)...

The isothermal compressibility of a general crystal is analyzed within classical density functional theory. Our approach can be used for homogeneous and unstrained crystals containing an arbitrarily high density of local defects. We start by coarse-graining the microscopic particle density and then obtain the long-wavelength limits of the correlation functions of elasticity theory and the therm...

The potential influence diagram is a generalization of the standard "conditional" influence diagram, a directed network representation for probabilistic inference and decision analysis [Ndilikilikesha, 1991). It allows efficient inference calculations corresponding exactly to those on undirected graphs. In this paper, we explore the relationship between potential and conditional influence diagr...

Data Warehouse (DWH) information is accessed by business processes. Today, no conceptual models exist that make the relationship between the DWH and the business processes transparent. In this paper, we extend a business process modeling diagram, namely the UML 2 activity diagram with a UML profile, which allows to make this relationship explicit. The model is tested with example business proce...

Through calculating the scatter diagrams of the streamfunction ( P or T) versus potential vorticity (PV) (qP or qT), where P and T are the planetary-scale streamfunction and total streamfunction, respectively, and using a weakly nonlinear NAO model proposed in Part I of this paper, it is suggested that negativeand positive-phase NAO events may approximately correspond to free modes even though ...

Exploration of new ferroic (ferroelectric, ferromagnetic or ferroelastic) materials continues to be a central theme in condensed matter physics and to drive advances in key areas of technology. Here, using thin-film composition spreads, we have mapped the functional phase diagram of the Ni-Mn-Ga system whose Heusler composition Ni(2)MnGa is a well known ferromagnetic shape-memory alloy. A chara...
