In this work, a task was set to study the rheological properties of zircon-based alloys with a modified chemical composition of the Zr-Nb and Zr-Nb-Sn systems with respect to the conditions of different processes of pressure metal treatment during manufacturing of pipes and rods. For this purpose, complex plastometric tests of new grades of alloys were carried out to obtain experimental data on the deformation resistance value σp and maximum permissible plasticity Λр of these materials. The tests were carried out on a modern plastometric apparatus in a wide range of thermal mechanical conditions of deformation according to different forms of loading. On the basis of the experimental data on the mechanical properties of the materials under study, pressure metal treatment processes were developed using the Forge 2008 computer modeling software package Normal 0 false false false RU X-NONE X-NONE /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Обычная таблица"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin-top:0cm; mso-para-margin-right:0cm; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0cm; line-height:115%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin;}

The influence of content of cryptocrystalline graphite of Kureysk Field, activated in a planetary centrifugal mill AGO-2, on the technological properties of mold coatings used for low-pressure die casting and castability of AK12 alloy are researched. It was found that the optimum properties of coating are achieved by the introduction into their composition 15 wt.% of activated graphite. Also it was found that with increasing content of graphite, the castability of AK12 alloy and roughness of castings are decreases.

Landsliding dynamics during recent decades within larch-dominant permafrost zone of Mid Siberia was analyzed. Studies were based on high and medium resolution data (QuickBird, WorldView, Landsat) and gravimetric measurements (GRACE). The landsliding occurrence increased since 2006 yr. Landsliding were located on southwest and southeast slopes only, and its number exponentially increased with slope steepness increase. The elevation limit of the landslides corresponded to the upper tree line. Landslides occurrence correlated with August precipitation (R 2 = 0.6) and drought index (SPEI: R 2 = 0.49), and with June-July-August gravimetric data (equivalent water thickness anomalies, EWTA: R 2 = 0.47–0.49). SPEI and EWTA are correlated (R 2 = 0.38). The significant increase of temporal divergence between maximal and minimal values of EWTA was observed.

This paper proposes a method to reduce the dimensionality of feature space for recognition of hyperspectral images. The method consists of dividing the spectral channels into blocks with high in-block correlation and the subsequent application of principal component analysis. It is shown that the proposed method allows to reduce the number of channels used in the classification by an order of magnitude with no significant degradation of recognition quality.

The technology of construction of vector fields of natural objects spatial displacements (ice fields, water masses, cloud formations in the atmosphere) at different times multispectral satellite data is discussed. The technology is based on finding the maxima of mutual correlation coefficient between two neighboring objects in a series of sequential images.
