Transducer for Measuring the Flow Rate of Fuel in the Manned Transport Spacecraft Soyuz
Measurement Techniques. 2016. Vol. 59. No. 5. P. 500-504.
Balakin S.
A fuel flow rate transducer design for a manned transport spacecraft is proposed. It is based on the principle of measuring the phase of the useful signal carrier frequency. This scheme significantly improves the stability of the instrument against mechanical interactions and provides more accurate measurements of the amount of fuel consumed by the spacecraft.

Layers of germanium (Ge) microrods with a core–shell structure on titanium foils weregrown by a metal-assisted electrochemical reduction of germanium oxide in aqueous electrolytes.The structural properties and composition of the germanium microrods were studied by means ofscanning and transmission electron microscopy. Electrochemical studies of germanium nanowireswere carried out by impedance spectroscopy and cyclic voltammetry. The ...

The article describes one of the powerful tools for the signals analysis while transmission – complex mathematics. Here the basic concepts (complex numbers, complex signal as expansion of a real signal to a complex-valued function) and some operations (exponentiation, absolute value and angular phase representation) are introduced.
As an example complex mathematical methods are used for ...

This handbook presents a set of calculated analytical formulas for determining the basic electrophysical parameters of electronic equipment: electrical capacity, inductance and wave impedance. These parameters play an essential role in ensuring the signal integrity and power integrity of electronic equipment and its electromagnetic compatibility. It is especially important to have design ratios when designing ...

Application of impedance spectroscopy for analysis of BeWo clone b30 human choriocarcinoma cell line
Nikulin S., Knyazev E., Gerasimenko T. et al., Placenta 2019 Vol. 83 P. e21
Objectives: BeWo cells are used for the construction of in vitro models of placental barrier. Only the early placenta possesses multiple trophoblast layers whereas third-trimester placenta consists of a single trophoblast layer. BeWo cells do not undergo contact growth inhibition and form multilayer structures. It is important to control the cell state for transport experiments. Impedance ...

A method of antenna element coupling control using a readjust of the surface impedance of the plane, it is mounted, is shortly described. A construction of a tunable frequency-selective metamaterial-made surface, which is designed to be a patch antenna element ground plane, is presented. Results of antenna VSWR measurements, which show the coupling change correspondingly ...
