In this paper the influence of materials properties on resonance frequencies is researched. It is shown how resonance drive and sense frequencies depend on material property.
Recently all CAD analysis and optimization techniques are moving from single or uncoupled problem solving in single domains to multi-disciplinary, multi- physics and multi-problem solving. This is the main reason why many commercial tools include modules for distributed collaborative design. Following article presents the review of the basic components and requirements to realization of different...
Collaboration between designers in different disciplines is an increasingly important aspect for the designing of complex objects and systems. Modern CAD systems have possibilities to handle this complexity, but regular modelling and designing technology supports only single product model and single user. This paper presents an analysis of different solutions for developing a real-time collaborative...
There is proposed the method of forming the stable criteria of radar compound object identification in the microwave band. This method is based on distraction of interference interaction of local reflection areas of the object shaping surface.

In this paper the coordinate method for aim direction angle and additional turn angle computation in Grad- and Uragan-like JVFS has been proposed. Accuracy characteristics have been analyzed. A navigation subsystem structure has been proposed. The introduced additional navigation equipment for JVFS allows march firing from unprepared locations in the view of topology. The firing location can be changed...
MEMS design flow should take in account every measure to include key steps involving in designing of MEMS device, but there are many variables which cannot be taken in account. Thus in this paper authors presented mathematical model of electrostatic microresonator in which mechanical and electrical parameters are used. Such model could be used during statistical analysis of electrical and mechanical...
In this paper the bus of PCI was developed for application in the personal computers. However lately the bus of PCI in one or another form all more frequent finds application in the embedded systems. Different methods allowing to make multitreatment in the real time with the use of the so-called bridges of PCI-PCI are presently used (PPB). It is needed expressly to differentiate the devices with symmetric...
A new inhibitory analogue WTA (winner-take-all) neural circuit which identifies maximal among N unknown input signals is proposed. As a building block the second order analogue globally stable neural network of Hopfield type is used. The connection matrix belongs to the class of diagonally stable block diagonal matrices and the activation functions are piecewise linear or sigmoid. The mathematical...
