Method of Selecting the Speed of Jack Pump Driving Motor Based on Reservoir Flow Rate

The sucker-rod oil pumping unit productivity is influenced by lots of factors, including the operation mode of the jack pump electric drive system. Settings of the electric drive system affect the system’s energy indicators, overhaul period and oil production volume. Therefore, an effective operation of oil production units is an important factor influencing the cost of the produced oil. The paper proposes a method of selecting the speed of the driving motor of the jack pump electric drive that allows balancing the sucker-rod oil pumping unit productivity and the reservoir flow rate.

Intellectual angle sensor for antenna systems and its metrological analysis

The design and electron-optical scheme of intelligent opto-electronic sensor of absolute angular position are proposed. The sensor is completed by microconverter for data processing to implement the detection and compensation a number of errors that caused by mechanical nodes of rotating mechanisms. The principle of the operation of proposed angle sensor are based on themethod of determining the absolute angular position using a code disk with one track. Pseudorandom code sequence of track is composed of different widths sectors.

Measurement method of electrical parameters of large dimension antenna systems

The method of measurement and evaluation of electrical parameters a larg antenna systems for ultra-high frequency bands is developed, that were not provided for the use of such antennas by their design. For ensure the necessary radio parameters in professional antenna systems (AS) use parabolic antenna reflectors with large diameters of 5 to 12 meters or more. The creation of such antennas require large expenditures for their production and metrological support by parameters setting.

Моделі оптимальних інформаційних систем на двовимірних комбінаторних конфігураціях

This paper belongs to the field of systems engineering and is aimed at improving the qualitative indices of vector data information technologies (e.g. 2D vector data coding design) with respect to reliability, precision and other significant operating characteristics of the systems based on the combinatorial configurations theory, namely the Ideal Ring Bundles (IRB)s.
