"In Semantic Web languages, such as RDF and OWL, a property is a binary relation: it is used to link two individuals or an individual and a value. However, in some cases, the natural and convenient way to represent certain concepts is to use relations to link an individual to more than just one individual or value. These relations are called n-ary relations. For example, we may want to represent properties of a relation, such as our certainty about it, severity or strength of a relation, relevance of a relation, and so on. Another example is representing relations among multiple individuals, such as a buyer, a seller, and an object that was bought when describing a purchase of a book. This document presents ontology patterns for representing n-ary relations in RDF and OWL and discusses what users must consider when choosing these patterns."
Retired professional graphic and fine artist. Creating unique plastic models and dioramas using artistic talent, skills and web resources and writing a blog about my experiences.
This study guide should provide you with a solid foundation for creating your own models. It is designed to be done in conjunction with Learning Lab 6, which provides a detailed lab for starting with an idea and ending up with a completed original model, although if you are new to NetLogo, you are probably better offer completing the earlier Learning Labs first as Lab 6 is more advanced.
The NetLogo User’s Manual provides a lot of good resources for learning NetLogo. These tutorials build upon many of them, drawing from the Programming Guide, and expanding on important concepts.
Icon Models, Toronto has partnered up with Japanese Forza Models in an effort to broaden their business potential and to provide more opportunities for their models.
Visual Paradigm, with products Visual Paradigm for UML (VP-UML), Smart Development Environment (SDE) and DB Visual Architect (DB-VA), is a world-recognized company in UML modeling and CASE tool technologies. VP-UML is a UML modeling tool that supports UML 2.1 with the most intuitive and innovative visual modeling user interface. SDE is a division of VP-UML that is fully-integrated into leading IDEs, including Eclipse and Visual Studio, to provide sophisticated code model synchronization capabilities. DB-VA is a single, easy-to-use object-relational mapping (ORM) environment which acts as a bridge between object model, data model and relational model.
Strictly spoken it's a piece of software, simulating the Solar System's bodies in 3D on your Windows or Linux PC (will work in most *NIX's as well). In difference to quite a few other programs it does so in realtime. Meaning you can view all the planets, moons and spaceships move along their paths, trace them, follow them, orbit them and even control them (time and spaceship contol). And you won't have to fight your way through hordes of green, slimey and one-eyed aliens for that ;-)
Software for constructing and reflecting on diagrams of one's ideas
Belvedere 4.1 is designed to help support problem-based collaborative learning scenarios with concept and evidence moodels, and provides multiple representational views (tables and graphs) on those models.
Belvedere was originally intended to help secondary school students learn critical inquiry skills that they can apply in everyday life as well as in science, but can be adopted to other applications as well.
