Computing the diameter of nanometer wood powder is the key step of intelligently acquiring wood powder mesh during processing and production in the wood powder manufacturing industry. To obtain the micro image of nano wood powder, the method of hole filling is adopted to fill the binary image of wood powder particles. The contours of wood powder particles are extracted with the use of the edge detection operator, and the control experiment is carried out accordingly. The shape line method is adopted while fitting the geometric shape of wood powder particles, and the longest side or diameter of the figure is solved so as to obtain the diameter. In addition, based on the conversion standard, the mesh number of particles is calculated. The method presented in this study is expected to facilitate the automation of wood powder pellet processing industry, whereas the method is also found to have optimal applicability and reference significance for the measurement of other sorts of particles.

The significant difference in the level of economic development of Russian regions allows us to consider their interaction as a relationship between the «center» and «periphery». The article highlights the factors that contribute to and hinder from production density in the «center». The author defines how economy digitalization influences these factors. To analyze the process of manufacturing industry density in Russia, we used regional data on employment and production volume in this industry from 2000 to 2016. The concentration level was estimated using the Herfindahl-Hirschman, Krugman, and CRN indices. The article demonstrates that there is an increase in geographical density of people employed in manufacturing industry in Russia. It is noted that labor productivity in manufacturing industry in the «center» consistently exceeds this indicator in the «periphery».

Rizal Ramli, a prominent national figure, senior technocrat and economist, argues that the government must reverse the logic built so far: Indonesia must first increase its economic growth to above 7%, then investment will surely come again. This paper is a his view of the economic conditions of the Jokowi era and how to rebuild Indonesia's economy going forward to rise from an alarming slump So far, he argues, deindustrialization has accelerated in the Joko Widodo era. The setback is marked by growth in the manufacturing industry sector until the third quarter of 2018 was 4.3% slower than the growth in the same period in 2017 at 4.8% and the processing industry growth rate is 4.3%, lower than the economic growth rate of 5%.
