“…Marking process was conducted via several passes to form two elements (substrate and code itself). To create the image which absolutely provides efficient QR code scanning, it is necessary to get this image with maximal contrast effect [15][16][17]; it is determined by correct selection of laser marking parameters. Thereby optimal parameters of marking application by laser device using experimental design method were determined in this work [18,19].…”

Laser marking of products and details is used more and more wide in different production areas, because it has undisputable advantages in comparison with other marking methods. Action of laser beam on the surface of marking product is the principal feature of laser marking. It is accompanied with local heating of this surface and its partial melting together with material evaporation from the surface contact point. Influence of laser impulse action on efficiency of marking on the surface of machine-building details is examined in this work. The samples of 08Kh18N10 steel were used as material. Marking was conducted by the system "MiniMarker 2-20A4", QR code was used as a marker. The marking parameters were optimized via the method of experimental design. The optimal marking procedure for getting maximal contrast of QR code was calculated and experimentally confirmed. Steel surface roughness was analyzed using profilograms. Contrasting effect and roughness of code were determined and relationship between these parameters was revealed. Contrast effect of marking increases with elevation of roughness. However, roughness has less input in increase of contrast effect comparing with colour hue of the surface of an information block and substrate. The link between surface roughness and contrast effect of marking is shown. Possibility of contrast effect assessment of QR code using profilometer is suggested.

The article examines the influence of global and local factors on the planning and implementation of large investment projects in the field of tourism in St. Petersburg. Analyzed the current and long-term political and economic factors that must be taken into account when developing a marketing concept for a cruise tourism project with a point of departure and end of routes in the city. The project includes the creation of an international cruise tourism center and a marine passenger shipping company, including the construction of a sea vessel. The negative influence of such factors as: political and economical confrontation with Western countries, aggravated in the period after 2014; restrictions on cross-border movements; increase in the audience of tourists from Southeast Asia. On the other hand, the implementation of the project can be favorably influenced by such factors as: internal political factors of competition between regional elites, the prevailing culture of cruise shipments on the Baltic Sea in the “ferry” format; the effect of replacing “shortfalls in foreign expenditures”; integration with the opening of the “Lakhta Center” and the direction of cinema tourism. An assessment was made of the degree of influence of these factors on the marketing concept of the project for the development of a cruise message and the terms of its payback.
