AB  - This paper considers the method of determining the initial orientation of the navigation and measuring complexes of mobile objects. The method is based on analytical gyrocompassing, using angular velocity sensors whose measurements are distorted by additive noise, with a priori uncertain statistical characteristics. The proposed approach requires small computational costs and can be effectively used in the development of high-precision systems of initial orientation of navigation-measurement systems of various mobile objects.

AB  - This invention is relevant when working as part of optoelectronic systems, including non-destructive quality control of forest seeds. The possibility of synthesis of the ultrafast optical analog-to-digital converter (ADC) providing conversion of analog information to digital in the sub-GHz range is considered. The functional scheme of the optical ADC, containing technologically well-developed optical elements is given; the principle of operation is described in detail. The possibility of increasing the speed of the ADC to make it potentially possible for optical data processing schemes is shown.

AB  - Research Highlights: One of the ways to improve the quality of a seedlot used in the forest nursery is the grading of seed by colour. Background and Objectives: The study is intended for forest's engineers and owners because it offers an alternative solution for forest seeds improvement before sowing. The success of forest establishment program mainly depends on the quality of Forest Reproductive Material. At this time usual practices during the seed processing is seed grading on size. This causes a lot of controversy about the possible reduction of genetic diversity through directional selection. Materials and Methods: Aiming to study the effect of seed coat colour on seedling performance, a one-year old container seedlings of Pinus sylvestris L. were planted at the post-fire site. Seedlings were produced from three fractions, previously graded in the visible wavelength range on a standard optical separator, plus control obtained without separation by colour. Results: Seedlings from different seed fractions performed differently in the first growing season after planting on the field. Seedlings from light seed fraction grow better in height, but those from dark seed fraction resulted with the highest survival rate. Light-dark seeds, which constitute the largest group in the initial sample by absolute weight, resulted with seedlings of the lowest growth rates and survival. The good results showed by seedlings from the control, for both growth rates and survival, indicate the weak effect of seed colour grading on seedlings field performance, but also the need for the more comprehensive studies in the future.

AB  - The study is intended for engineers and small-scale forestry owners because it offers a simple solution for acorns quality improvement by machine grading before sowing. Visible diffuse reflectance spectra of single whole acorns (Quercus robur L.), damaged acorns, acorns pericarp, whole and damaged acorn seeds were scanned with spectrometer USB 4000 (Ocean Optics Inc., USA) from 450 to 900 nm at 1 nm intervals. Near infrared reflectance spectra of single acorns material were scanned with spectrometer NirQuest512 (Ocean Optics Inc., USA) from 900 to 2100 nm at 1 nm intervals. English oak acorns cannot be divided from damaged acorns and acorns pericarp in the visible wavelength range. Hard-to-release damaged acorns with shell cracks are eliminated in the NIR-reflectance at a wavelength range from 1400 to 1500 nm or from 1900 to 2000 nm. After the elimination of damaged acorns, good whole acorns can be grading from the acorns rotten seed and acorns pericarp (only one the inner side of a shell) at a wavelength range from 1600 to 1700 nm. The results of this study are limited to these specific samples and cannot be interpreted for acorns of all Quercus species.
