By using an intelligent measuring system, the necessary preparation and measurement of the deformation of the PCB during the separation of the module (board with mounted electronic components) from the panel was performed. An area of critical deformation is defined based on the standards for testing in surface mounting. The results of practical measurements of deformations after separation of modules from panels are presented. A conclusion is made on the basis of the obtained results with conclusions regarding the admissibility of the process according to the standard.

The paper analyses radon (222Rn) hazardous industrial facilities and dwellings in Ukraine. The importance of control and monitoring as well as integrity and accuracy of the 222Rn measurements at the radon hazardous facilities are highlighted. Development of the standard source of 222Rn based on the uranium ore is described including research of uranium ore samples, their specific activity and radon emanation rate and optimization of the construction. The developed primary standard source provides stable 222Rn emanation, effectiveness and reliability of operation, safety of environment, available and cost-effective material generating 222Rn. The operation of the standard sources as a part of the State primary standard of 222Rn volumetric activity is described in the paper. Options of the standard source applications for calibration of the measurement tools for 222Rn volumetric activity are also demonstrated including mobile radioecological monitoring stations required for development of effective actions minimizing 222Rn levels in the environment of radon hazardous industrial facilities and living premises.

The main purpose of research and development in the field of safe landing of aircraft is to increase the reliability of the assessment of the light signal system. The approach to increase the reliability of the system evaluation by measuring indicators of the light signal picture of airports due to the use of statistical methods is considered. The use of statistical approaches to assess the state of the light signal system of airports makes it possible to optimize the modes of their service and determine the stock of light signal lights. But the problem of reliability of system estimation on measuring indicators of a light signal picture of airports with use of the system approach is not solved at present. In the offered work as an indicator of quality to consider an indicator of brightness of separate components of a light signal system of the airport. Statistical methods were also used to process the measured luminance indicators to decide on the state of the light signal system of airports. The use of statistical approaches to assess the state of the light signal system of airports makes it possible to optimize the modes of their service and determine the stock of light signal lights.

The article presents the research results in the instruments and experimental techniques field and proposes the criterion-based assessment method of the probability of deviation of various objects from the normal state based on the measuring results of their parameters. The developed criterion can take values in the range from zero to one, the more the criterion numerical value approaches one, the less the object state probability of deviation from the norm. The results of the experimental studies and application of the proposed criteria-based assessment methodology are presented on the example of the occurrence of short-circuited turns in the winding of an asynchronous electric motor. The research results presented in the article can be used to assess the probability of deviation from the normal state of the different types of objects.

This paper presents a modification of objective PSNR metric for image quality measurement and evaluation. In the modified metric the MSE is substituted by 3 different distance measures: MAE, Euclidean distance and Canberra distance. All metrics were tested with 12 different 3-channels, 8-bits images. Every test image was distorted by 10 different values of dispersion of white Gaussian noise with zero mean. The experiments show that the dispersion of the PSNR with Euclidean distance has the lowest standard deviation and thus improved the original PSNR. It is also suggested that due to normality of the data and their deviation, the results has to be accepted with some standard uncertainty.

Different types of angular orientation and micro-positioning systems with flexures are used in different areas of precision mechanical engineering. Depend on the design, they can be assembly of different components or monolithic. The lack of friction gives them an advantage when they are used in different systems, where there is no possibility for maintenance or the environment is heavily polluted, but requires high accuracy and minimal deviation of the axis of rotation. This report presents the results of a study of different types of flexures based on the “butterfly” design. Based on the results an improved flexure design is introduced to reduce the deviation of the axis of rotation and to increase the working range of the micro-positioning elastic modulus.

The report presents the methodology and difficulties in developing a capacitive transducer for angular displacement. Experimental studies of the developed converter are presented, as the measurement of the capacity is performed by two independent methods. Mathematical models are derived giving the relationship between the value of the capacitance and the area of overlap and the distance between the electrodes.
