This research is connected with the expansion of global satellite navigation systems application. All the experiments conducted were devoted to the development of the algorithm of obtaining the mobile objects orientation angles using satellite signals. For obtaining and processing of experimental data adaptive filters were used. The results obtained can be applied for solving a ...

In the paper authors compare additive manufacturing processes that use wire and processes that use metal powder. Also, there are new results of author’s investigates in Electron Beam Free Form Fabrication process.

This work describes a method and apparatus designed to combat AFS, whose operating principle is based on the temperature regulation in the well. Also, the paper presents a demonstration of physical and mathematical formulas for the software to implement the full automation in the management of the developed device.

Currently, all methods of permanent connection materials mainly used is welding. It is less time consuming and saves a lot of metal. In particular, the replacement of riveted joints welded allows to reduce the weight of the structure of carbon steels are 10 to 25% by reducing the cross-sectional areas of the connection. In addition, welding provides a particularly high degree of ...

Diffuse reflectance spectra were studied sample forage corn, turf various moisture in the wavelength range 1000-2700 nm. Were constructed calibration equation using two-factor regression model, factors which favor the optical density at the absorption bands of 1445 nm and 1934 nm, respectively.

The present paper addresses the general problems which have to be faced with while sampling and definition of properties of formation fluid as a result of PVT trials. The most important questions here are sampling of clean and representative samples of plutonic formation fluid and rapid and relatively easy way to receive valid and accurate data of fluid extracted for the moment ...

The paper includes development process of software tools applicable to aviation technologies. The development is made by the use of the software system IDE. Usage environment of operative aeronautical equipment is simulated by means of represented software tools.

In the paper is presented the analysis of the possibilities of achievements in power supply systems with digital monitoring and control system. Are described the possibility of implementation in digital system. Caused the improvement of the quality of electricity, increasing availability and decreasing labor costs for maintenance. Also are provided requirements for the construction ...

As a result of modeling of influence of laser radiation at soldering of terminating connections of integrated microcircuits optimum parameters of process are defined: power of radiation, beam radius, influence time.

Under the rainproof shelter and pot cultivation conditions, we use two oat varieties, rietyan5’ and‘ Baiyan2aiyanesns, we effect of two water (45%, 75% field water capacity (FWC)) and spraying humic acid water soluble fertilizer at different growth stage on drought resistance, yield formation and quality. We hope to reveal the mechanism of water and humic acid water soluble ...
