Abstract
Standardization is a prerequisite for creating an optimal order in the economy and social life of each country. It is an integral part of science, as any science to manufacture certain products is based on standardized terminology, technical safety requirements and test methods for assessing the conformity of the quality characteristics of the products. Without standardization it cannot be achieved advanced technical guidance on the production and marketing of products.

Model-Based Fault Diagnosis in a Waste-Processing Industrial System via Causal Graphs
The paper describes a Casual Graph (CAG) approach to fault diagnosis of industrial systems, based on logical and qualitative methodology for modelling the diagnostic aspects of a system structure and behaviour. The main...
Simulation of Double Acting Pneumatic Cylinder Control
Implementing optimal control in a pneumatic driven system is not a very cheap or easy process. The control subsystem of a pneumatic driven system has to distinctive direction: the control from pneumatic point of view and...
Modelling and Simulation of Pressure Limiting Valve Based on Input and Output Data
The article presents an original mathematic model of a direct drive pressure limiting valve, establishing the status of each variable as input or output data, respectively, underling the two stages of the valve: before a...
Space Vector PWM Signal Generation for Twelve-Level Inverter Using Reference Signals
A refined space vector modulation scheme for a twelve-level inverter system for dual-fed induction motor drive, using only the instantaneous sampled reference signals is presented in this paper. The dual-fed structure is...
Evolution of the Solid Fraction at the Solidification of a 0.1 %C Steel
To achieve mathematical models and software for solidification simulation casted pieces it is necessary to know the fraction of the solid variation at solidification. In the case of the alloys form solid solution by soli...
