A µBRDF goniospectrophotometer has been developed at LNE-CNAM. This device performs traceable BRDF measurement with a measurement surface of 30 µm of diameter. All angular configuration of measurement belonging to the hemisphere are possible. The spectral range is the visible. This device intends to help to progress in the effort to extent the BRDF metrological scale from the centimetre size to micrometre size. Traceable µBRDF measurement are requested today to validate physical based rendering models used in virtual prototyping and to progress in the comprehension of the appearance of natural material like wool, wood, or leather.

Results of experimental studying radiation spatial structure of atmosphere background nonuniformities and of an unmanned aerial vehicle being the detection object are presented. The question on a possibility of its detection using optoelectronic systems against the background of a cloudy field in the near IR wavelength range is also considered.

Business Process Analysis can be used to eliminate or reduce a waste cost caused by non value added activities that exist in a process. This research aims at evaluating activities carried out in the natural material procurement process in the PT XYZ, calculating the effectiveness of the process cycle, finding a way to improve the process management, and calculating the cost reduction that can achieved by activity management. A case study was the approach of this research. The researcher obtained research data throughout deep interviews with the staff who directly involved in the process, observation, and documentation of natural material procurement. The result of this study show that the effectiveness of the process cycle of natural material procurement in the factory reached as much as 87,1% for the sand material and 72% for the crushed stone. This indicates that the process still carry activities with no added value and still contain ineffective costs. Through the Business Process Mechanism, these non value added activities can be managed so that the process cycle becomes more efficient and cost effectiveness is achieved. The result of the effective cycle calculation after the management activities implementation is 100%. This means that the cost of natural material procurement process has become effective. The result of calculation of the estimated cost reduction as a result of management activity is as much as Rp249.026.635,90 per year.

The article examines the impact of digitalization on human life and intellectual experience. The development of computer technology demands an understanding of new aspects of human development and requires a capability to overcome not only external conditions but also ourselves. Entering a new level of development cannot imply a complete rejection of previous dispositions, but should be accompanied by reflection on personal experience and by the quest for new forms of interaction in society and with nature. Communicative and cognitive activity of a person has an ontological basis and relies on processes that actually evolve in nature. Therefore, the creation of new objects is always associated with the properties of natural material and gives rise to new points of support in the development of man. The more audacious his projects, the more important it is to preserve this connection to nature. It is always the human being who turns out to be the initiator who knows how to solve problems. The conformity of complex technical systems to nature is not only a goal but also a value of meaningful construction of development perspectives. The key to the nature orientation of the modern digital world is the human being himself, who keeps all the secrets of the culture of his natural development. Therefore, the proposed by the Russian philosopher V.S. Stepin post-non-classical approach, based on the principle of “human-sizedness,” is an important contribution to contemporary research because it draws attention to the “human – machine” communication, to the relationship between a person and technological systems he created. The article concludes that during digital transformation, a cultural conflict arises: in an effort to solve the problems of the future, a person equips his life with devices that are designed to support him, to expand his functionality, but at the same time, the boundaries of humanity become dissolved and the forms of human activity undergo simplification. Transhumanism engages society in the fight against fears of vulnerability and memory loss and ignores the flexibility and sustainability of natural foundation.
