This paper presents an extension of our Mathematica- and MathCode-based symbolic-numeric framework for solving a variety of partial differential equation (PDE) problems. The main features of our earlier work, which implemented explicit finite-difference schemes, include the ability to handle (1) arbitrary number of dependent variables, (2) arbitrary dimensionality, and (3) arbitrary geometry, as well as (4) developing finite-difference schemes to any desired order of approximation. In the present paper, extensions of this framework to implicit schemes and the method of lines are discussed. While C++ code is generated, using the MathCode system for the implicit method, Modelica code is generated for the method of lines. The latter provides a preliminary PDE support for the Modelica language. Examples illustrating the various aspects of the solver generator are presented.
Pythagorean fuzzy sets have a lot of applications in the field of engineering and scientific problems. Also, besides, the power averaging (PA) operator can reduce the influence of evaluating extreme data from some bia...

The standard IEC/EN 61508 defines the requirements for safety systems to be applied to industrial plant safety independently of the application. It is not only intended as a basis for the development of future application orientated standards, but also as a basis of all safety related electrical, electronic and programmable electronic systems, in order to apply it to safety critical applications. The purpose of this paper is to describe the SILCas tool which enables the user to determine the Safety Integrity Level (SIL) and the probability of failure on demand (PFD) for entire SIFs (consisting of sensor, signal processing, actuator) and for different system architectures.
When dealing with complex systems design and application the notion of ontologies helps the process of application integration. To solve the problems with discover, interpret and reuse data we have to recognize ontolo...
