The method of construction of confidential boundaries for probability density is suggested and its efficiency related to probability characteristics of procedure of decomposition of the range of random quantity variation is studied.

Examined the work principal of tracking system, based on technology of photogrammetry, researched mathematical apparatus, explored working algorithm for the system and software.

Describes how to install and method of determining the mode composition of radiation of laser diodes (LD) with quantum wells heterostructures separate restrictions. Method allows to determine taking into account the peculiarities of laser beams with a large divergence whether the mode of generation LD single-mode fibers. In the work of the first established that the radiation pattern of single-mode laser diodes can be set in elementary functions, which greatly facilitates the implementation of the developed technique.

The quastions of evalution of uncertainty of measurements at development of pulsating fluid flow systems for verification of non-invasive sphygmomanometers are considered. The results of experimental studies of accuracy of installation for complete verification of these measuring insruments are presented.
