2. 1. PDEModelica – A High-Level Language for Modeling with Partial Differential Equations

   Author : Levon Saldamli; Peter Fritzson; Bernhard Bachmann; Francesco di Casella; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; mathematical modeling; PDEModelica; Modelica; object-oriented modeling; equation-based modeling; declarative modeling; high-level modeling languages; mathematical modeling languages; Computer science; Datavetenskap;

   Abstract : This thesis describes work on a new high-level mathematical modeling language and framework called PDEModelica for modeling with partial differential equations. It is an extension to the current Modelica modeling language for object-oriented, equation-based modeling based on differential and algebraic equations. READ MORE

4. 2. Four Proposals for Enterprise Modeling

   Author : Darek Eriksson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; change; development; enterprise; modeling process; enterprise modeling language; systems science; constructivist epistemology; organization; modeling; multi-modal modeling; model;

   Abstract : Any enterprise whether a major corporation, a small family-owned business, a public school, a hospital, or a military unit needs to develop itself continuously in order to adapt to the challenges originating within itself and from its environment, in relation to its overall purpose or mission. Deliberate development and management of an enterprise manifest complexity that gives rise to a central challenge: how can we obtain a comprehensive intelligibility of an enterprise? One conceptual tool to overcome this challenge is enterprise modeling; it supports articulation of an enterprise and consequently intelligibility of its complexity. READ MORE

5. 3. Design and Implementation of Object-Oriented Model Libraries using Modelica

   Author : Hubertus Tummescheit; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modeling languages; thermo-fluid systems; process modeling; process control; control systems; thermo-hydraulic systems; non-linear models; model library design; object-oriented; modeling; simulation; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

   Abstract : This thesis describes basic models for thermo-fluid systems and the implementation of the models using a flexible object-oriented structure in the ThermoFluid library. Model libraries provide an excellent way to package engineering knowledge of systems to be reused by non-experts. READ MORE

6. 4. Situated Embodiment : Studies in the emergence of spatial meaning

   Author : Jordan Zlatev; Chris Sinha; Stockholms universitet; []
   Keywords : HUMANIORA; HUMANITIES; Languages and linguistics; Språkvetenskap; General Linguistics; allmän språkvetenskap;

   Abstract : What does it mean to know a language? How do children acquire language, seemingly spontaneously? How is intersubjective linguistic meaning made possible? How are people able to understand utterances which they have not heard before? General questions such as these are of primal concern for modem theoretical linguistics. At the same time the dominant theoretical approach to answering them, generativism, has given rise to persistent anomalies and confusions. READ MORE

7. 5. Meta-Languages and Semantics for Equation-Based Modeling and Simulation

   Author : David Broman; Peter Fritzson; Jeremy Siek; Thomas Schön; Björn Lisper; Walid Taha; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Meta-language; semantics; EOO; Modelica; equations; modeling; simulation; MKL; Computer science; Datalogi;

   Abstract : Performing computational experiments on mathematical models instead of building and testing physical prototypes can drastically reduce the develop cost for complex systems such as automobiles, aircraft, and powerplants. In the past three decades, a new category of equation-based modeling languages has appeared that is based on acausal and object-oriented modeling principles, enabling good reuse of models. READ MORE
