Virtual labs are valuable educational resources in control education, and are widely used in the process industry as tools for operator training and decision aid. In these application domains, virtual labs typically rely on the interactive simulation of large-scale hybrid-DAE models with components of different engineering domains, whose descriptio...

... communication framework is based on the TCP protocol and a multiple client server architecture. There is one model simulation and multiple views, that are connected to the model simulation using a peer to peer centralized network, as is shown in Fig. 2. The communication engine is embedded in each view and the model, which are always synchronized in the same model state. The model simulation stops at regular time steps to exchange TCP messages with each view, a process explained ...

The paper considers various technologies for creating virtual laboratories used for teaching in the natural sciences and technical disciplines in schools and universities. Particular attention is paid to technologies for creating laboratories using visual modeling environments: Matlab-Simulink, LabView, OpenModelica, MapleSim, System Developer, AnyDynamics, SimInTech. It is proposed to start a discussion of the project "Public Virtual Libraries" on the pages of the journal "Computer Tools in Education"
Printed circuit boards (PCBs) are essential modules which are incorporated in a wide range of industrial equipment in order to control or signal manipulation applications. Printed circuit boards are subjected to various types of loads, such as vibrations, shocks and static loads. This paper discusses the development and use of an analytical approach for predicting the dynamic response of a flexible printed circuit board (PCB) at an early stage of design. The main contribution of this research work is to reduce the designing time and to increase efficiency, computer simulation (modeling) commonly used. As an application, the dynamic response of a simply supported circuit board, during the drop test, to an impact load applied to its support contours is presented and discussed using the modeling software tool Modelica/Dymola. An overview of the desired system behavior can be performed and the effects of some parameters on the system response can be analyzed. The model can be helpful in the analysis and the design of PCB structures experiencing dynamic loading in the preliminary vibrational design. For validation purpose, the obtained results are compared with those reported in the literature.
