A new language called Modelica for hierarchical physical modeling is developed through an international effort. Modelica 1.0 [http://www.Dynasim.se/Modelica] was announced in Septem-ber 1997. It is an object-oriented language for modeling of physical systems for the purpose of efficient simulation. The language unifies and generalizes previous(More)
Applications in scientific computing operate with high-volume numerical data and the occupied space should be reduced. Traditional compression algorithms cannot provide sufficient compression ratio for such kind of data. We propose a lossless algorithm of delta-compression (a variant of predictive coding) that packs the higher-order differences between(More)
Applications in scientific computing operate with data of complex structure and graphical tools for data editing, browsing and visualization are necessary. Most approaches to generating user interfaces provide some interactive layout facility together with a specialized language for describing user interaction. Realistic automated generation approaches are(More)
ObjectMath is a high-level programming environment and modeling language for scientific computing which supports variants and graphical browsing in the environment and integrates object-oriented constructs such as classes and single and multiple inheritance within a computer algebra language. In addition, composition of objects using the part-of relation(More)
The complexity of mechanical and multi-domain simulation models is rapidly increasing. Therefore new methods and standards are needed for model design. A new language , Modelica, has been proposed by an international design committee as a standard, object-oriented, equation-based language suitable for description of the dynamics of systems containing(More)
1. ABSTRACT Computational resources can be used with higher efficiency if the CPU load is distributed on many computers. A flexible system for task distribution has been designed. Multiple tasks are organized into a queue, and when possible, are sent for execution to idle computers on the network. The CORBA standard is used for control and data sending over(More)
