DESIGN Cross-sectional studies in Russia (n = 502) and Macedonia (n = 205), with fluorochrome-stained sputum examined by 1) the new Lumin light emitting diode (LED) fluorescent attachment on a light microscope, and 2) conventional fluorescent microscope (CFM) available in each laboratory, and compared to 3) Ziehl-Neelsen (ZN) restaining/reading of the same(More)
Two operational-and-tactical factors had the main influence on organization of the surgical care rendered to the casualties on the Northern Caucasus: the fulminant and maneuverable nature of combat operations at the beginning of both armed conflicts and rather small territory of war theatre. The main special features of organization of surgical care to the(More)
Detection of motion with parallel plate capacitors is commonly used in MEMS; small amplitude of motion is typically assumed. In this paper, we derive precise and constructive equations for the case of parallel plate capacitive detection of arbitrary amplitude of motion. These equations are solved in closed form without using a small displacement assumption.(More)
— We report a new approach for improvement of the long term in-run bias stability of Coriolis vibratory gyroscopes. The approach is based on utilization of the mechanical quadra-ture error in gyroscopes to compensate for variation in system parameters. The proposed approach was validated by a silicon Quadruple Mass Gyroscope, with the natural frequency of 3(More)
This paper analyzes energy dissipation mechanisms in vacuum-operated in-phase and anti-phase actuated micromachined z-axis vibratory gyroscopes. The type of actuation is experimentally identified as the key factor to energy dissipation. For in-phase devices, dissipation through the die substrate is the dominant energy loss mechanism. This damping mechanism(More)
201 INTRODUCTION Innovation projects are dealt with in a variety of areas that are studied separately (technical, technoo logical, organizational, economic ones, knowledge management) and employ various management mechanisms that are typical of these systems. This is why the theory and practice of innovation managee ment were previously developed by solving(More)
We report vacuum packaging procedures for low-stress die attachment and versatile hermetic sealing of resonant MEMS. The developed in-house infrastructure allows for both high and moderate-level vacuum packaging addressing the requirements of various applications. Prototypes of 100 µm silicon-on-insulator Quadruple Mass Gyroscopes (QMGs) were packaged using(More)
Keywords: MEMS gyroscope Angle measuring Whole angle Rate integrating Quality factor Bandwidth a b s t r a c t We report detailed characterization of a vacuum sealed rate integrating silicon MEMS gyroscope. The new gyroscope utilizes geometrically symmetric, dynamically balanced quadruple mass architecture, which provides a combination of maximized quality(More)
Existing electrooptical experimental techniques applied to a colloid solution allow the determination of different particle parameters, such as rotary diffusion coefficient, size, polarizability anisotropy and others. If the solution is polydisperse, numerical methods can be used to determine the distribution of particles in the solution on their(More)
