Micro fluidic system holds promise for many novel applications where rapid mixing is important and has lead to number of developments. Despite of major developments no systematic study has been carried out so far to understand the effect of flow mechanism and geometry on microfluidic mixing. This work focuses on mixing analysis of low Reynolds number (<;25) fluids in T-shape passive micro mixer...
This paper presents the derivation of the state equation of projects that incorporates project size, project duration, project total effort, team size, team productivity and project difficulty. In contrast to existing bottom-up methods of project presentation in the form of statistical relationships between project parameters this new top-down methodology is not a data driven and therefore is more...
In this paper the transient heat conduction problem for a semi-infinite layer with a coating that is heated changing in time and uniformly distributed over its lateral surface of the heat source is discussed.
The method of building of thermal models based on the study of features of design and technological solutions of technical objects, thermal relations and design tasks was developed.
Iii the paper VHDL-AMS model for computer- aided design of MEMS tuning fork gyroscope has been created. The created model allows to model drive and sense vibrations, variations of Coriolis acceleration, capacitance and current changes of the device depending on the applied angular velocity, and also to make its functioning analysis on the schematic level of computer- aided design.
In this paper, a model for computer-aided design of the micromechanical z-axis gimbaled gyroscope has been created using VHDL-AMS. The created model allows to model drive and sense vibrations, current changes, output voltage, sensitivity of the device depending on the applied angular velocity, and also to make the functioning analysis of such device on the schematic level of computer-aided design.
In this paper, the mathematical model of vibrations of the micromechanical gyroscope and the design algorithm of the constructive parameters of its working elements are proposed.
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 mathematical model of the basic constructions of fluidic micropump with piezoelectric actuator for design on a component level is presented. The method of eventual differences is used for solve of task for determination of displacements and tensions. Resulted results of dependences of initial characteristics from the enclosed the voltage.
