This paper describes the development and experimental study of a software and hardware complex designed for studying the conductive tracks of printed circuit boards. In the course of this development, a subminiature eddy-current transducer and a measuring system capable of performing measurements using the newly developed transducer were created. The paper contains descriptions of the main parameters of the developed measuring system, and also presents the results of experiments conducted with various printed circuit boards, both with defect-free and those with artificial model defects. These experiments made it possible to confirm the possibility of using the developed measuring system and eddy-current transducer for controlling the conductive tracks on printed circuit boards and determining their quality.

The ship electric field has become a new physical field which is widely concerned at home and abroad in recent years. For the research of ship electric field, one of the most effective methods is to measure it underwater. According to the analysis of ship electric field signal’s characteristics, the ship electric field measurement system based on MSP430F149 was designed and the key technologies of software and hardware were also presented in this paper. The results of experiment demonstrated that the system could effectively measure the ship electric field signal in a low SNR. Meanwhile, it has the advantages of low power consumption, high accuracy and credible.

A numerical study with FLUENT software has been carried out as to air performance in the slope solar energy power plant. The velocity field, temperature and pressure fields in the solar chimney, and the simulated result were compared with the simulated result of traditional solar chimney power generating equipment. The simulation results show that distribution of the temperature field and the velocity field in slope solar energy power plant and traditional solar chimney power generating equipment. In the case of the same height, the velocity of traditional is slightly larger than the slope style's, but there is little difference. In order to achieve the same power generation effect, the overall height of slope style is more than the traditional style, but the vertical chimney height of traditional style is greater than the slope style. The cost of construction of vertical chimney is expensive, and many problems have been considered, like radix saposhnikoviae and earthquake prevention, the heat collector also need to be cleaned on time. The slope style can take full advantage of land, the height of vertical chimney will be reduced, so the construction of the chimney will be relatively easy. Rainwater can clean the heat collector when it runs down from it. All things considered. The slope solar energy power plant has more development prospects.

Aim. To study the effectiveness and benefits of blood pressure (BP) remote monitoring in outpatients with hypertension.Material and methods. The study included 100 patients with a verified diagnosis of hypertension, who didn’t achieve target BP pressure levels. The patients measured their BP twice a day over 6 months with facilities with automatic data transmission over GSM-channel to a remote monitoring center. BP parameters were being transmitted online to the remote monitoring center, where they were being processed and transferred to the personal account planner (created by the Web interface based on the software and hardware complex) of the attending physician and operator of the remote monitoring center. It is important that doctor received information only on clinically significant measurement results, based on which he determined the urgency of contact with the patient and the further tactics of his management.Results. No malfunctions in the work of communication facilities, technical failures in the software and hardware complex were registered over the entire period of the study. After 6 months of the monitoring it was possible to achieve target BP levels less than 135/85 mm Hg in 70% of patients. The proportion of patients with a high level of normal BP increased from 10% to 19%, while the proportion of patients with grade 1 and 2 of hypertension decreased significantly (from 33% to 7% and from 54% to 3%, respectively). At the beginning of telemedicine monitoring 3% of patients had stage 3 of hypertension, at the end of the study – 1%.Conclusion. The technology of telemedicine monitoring has shown itself as a simple, affordable and reliable way of management of outpatients with hypertension in conditions of real clinical practice. It was possible to achieve BP levels less than 135/85 mm Hg in 70% of patients by the method of remote outpatient monitoring. BP remote monitoring changed fundamentally the decision-making strategy of the patients management: it was not the patient who independently determined the need for consultation with a medical professional, but the attending physician made a decision on the method and urgency of contact with the patient on the basis of the data of objective monitoring indicators.
