Combined use of modeling techniques for the development of the conceptual model in simulation projects
The objective of this paper is to utilize the SIPOC, flowchart and IDEF0 modeling techniques combined to elaborate the conceptual model of a simulation project. It is intended to identify the contribution of these techniques ...
Ontologias e Unified Modeling Language: uma abordagem para representação de domínios de conhecimento.
This article emphasizes the use of Unified Modeling Language, UML in the specification of models based on ontologies in the representation of domains of knowledge, emphasizing the importance of semantic and of treatment ...

MOOGLE: a metamodel-based model search engine
(SPRINGER HEIDELBERGHEIDELBERG, 2012)
Models are becoming increasingly important in the software development process. As a consequence, the number of models being used is increasing, and so is the need for efficient mechanisms to search them. Various existing ...
Comparison of friction models applied to a control valve
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
Eight different models to represent the effect of friction in control valves are presented: four models based on physical principles and four empirical ones. The physical models, both static and dynamic, have the same ...
Comments about some species abundance patterns: classic, neutral, and niche partitioning models
(Int Inst Ecology, 2008-11-01)
The literature on species abundance models is extensive and a great deal of new and important contributions have been published in the last three decades. Broadly speaking, one can recognize five families of species abundance ...
Towards an intelligent graphical interface for linear programming modelling
The increase of computing power of the microcomputers has stimulated the building of direct manipulation interfaces that allow graphical representation of Linear Programming (LP) models. This work discusses the components ...
On liability dollarization: a simple model with domestic and foreign creditors
(Universidad de San Andrés. Departamento de Economía, 2011)
Is it physically sound to add a topologically massive term to three-dimensional massive electromagnetic or gravitational models?
(World Scientific Publ Co Pte Ltd, 2006-01-30)
The addition of a topologically massive term to an admittedly nonunitary three-dimensional massive model, be it an electromagnetic system or a gravitational one, does not cure its nonunitarity. What about the enlargement ...
