Abstract — the counting efficiency of a three-layer diamond detector of gamma radiation based on single-crystal diamond is considered. The paper specifies the of measurements of the absolute effective charge counting rate of a single-layer, two-layer, and three-layer diamond detector are presented. The use of a three-layer structure of a diamond detector, makes it possible to enhance the amplitude of charge output spectrum, to expand the detector dynamic range, as well as to improve the accuracy and information content of radiation monitoring systems.
A radiation-resistant diamond-based detector for registration of fluxes of particles of cosmic radiation with low linear energy transfer is developed and investigated. The device may be used to register gamma radiation of water-moderated, water-cooled nuclear energy reactors. The characteristics of a detector when exposed to beta radiation are determined and modeling of the signals of the device when exposed to beta and gamma radiation is performed. The use of a multi-layer diamond structure makes it possible to increase the signal-to-noise ratio and expand the dynamic range of measurements of the linear energy transfer of cosmic radiation particles.
Theoretical approaches to the construction of a spectrometric diamond detector of fluxes of ionizing radiation are considered. The device is intended for continuous monitoring of the radiation conditions onboard space vehicles for quickly arriving at decisions as regards active protection and prediction of the remaining life of space transportation systems.
The review highlights the parameters of multilayer diamond detector for monitoring space radiation based on CVD diamond technique. The paper specifies the results of measuring charge output spectrum of single and double layer diamond detectors. Diamond detector serves to on-board radiation monitoring systems of spacecraft having lifetime increase in up to 20?25 years. The use of a diamond detector multi-layer structure makes it possible to enhance the amplitude of charge output spectrum, to expand the detector dynamic range, as well as to improve the accuracy and information content of radiation monitoring systems.

Описывается созданный макет манипулятора с биоэлектрическим управлением. Манипулятор сделан в форме человеческой ладони, движение пальцев которой управляется через электромиосигналы оператора. В среде LabVIEW разработан виртуальный прибор, позволяющий с помощью дискретного вейвлет-преобразования осуществить анализ электромиосигналов оператора, определить моменты мышечной активности и сформировать по результатам анализа сигналы управления манипулятором.

The paper provides a number of proposed draft operational guidelines for technology measurement and includes a number of tentative technology definitions to be used for statistical purposes, principles for identification and classification of potentially growing technology areas, suggestions on the survey strategies and indicators. These are the key components of an internationally harmonized framework for collecting and interpreting technology data that would need to be further developed through a broader consultation process. A summary of definitions of technology already available in OECD manuals and the stocktaking results are provided in the Annex section.
