Complex products are increasingly consisting of both software and hardware components which are closely interacting. Thus, modeling tools and processes need to support co-design of software and hardware in an integrated way. Currently, UML is the dominant graphical modeling notation for software, whereas Modelica is the major object-oriented mathematical modeling language for component-oriented modeling of complex physical systems, e.g., systems containing mechanical, electrical, electronic, hydraulic, thermal, control, electric power or process-oriented subcomponents. Here we present the first comprehensive UML-Modelica-SysML integrated modeling environment as a ModelicaML profile integrated in Eclipse. The profile reuses artifacts from the System Modeling Language (SysML) profile, and combines the major UML diagrams with Modelica graphic connection diagrams. Requirement, equation, and simulation diagrams are also supported in an integrated way. Moreover, the availability of the UML-style internal class diagram view for Modelica classes may also ease the understanding of modeling with Modelica for software developers with a UML background.

In order to support the development of complex products, modeling tools and processes need to support co-design of software and hardware in an integrated way. Modelica is the major object-oriented mathematical modeling language for component-oriented modeling of complex physical systems and UML is the dominant graphical modeling notation for software. In this paper we propose ModelicaML UML profile as an integration of Modelica and UML. The profile combines the major UML diagrams with Modelica graphic connection diagrams and is based on the System Modeling Language (SysML) profile.
In this paper we present the ObjectMath language, a hybrid language integrating object-oriented constructs with features for symbolic and numeric computation. Complex mathematical models may be implemented in a natura...

Completely annotated lambda terms (such as are arrived at via the straightforward encodings of various types from System F) contain much redundant type information. Consequently, the completely annotated forms are almost never used in practice, since partially annotated forms can be defined which still allow syntax directed type checking. An additional optimization that is used in some proof and type systems is to take advantage of the context of occurrence of terms to further elide type information using bidirectional type checking rules. While this technique is generally effective, we show that there exist bidirectional terms which exhibit asymptotic increases in the size of their type decorations when sequentialized into a named-form calculus (a common first step in compilation). In this paper, we introduce a refinement of the bidirectional type system based on strict logic which allows additional type decorations to be eliminated, and show that it is well-behaved under sequentialization.
