A detailed theoretical analysis of properties of non-contact system for deformation measurement of industrial and engineering structures with digital image method is described in the article. The relations allowing to calculate all parameters of the measuring system are derived and the process of calculation is shown using commercially available components. and V článku jsou podrobně teoreticky analyzovány vlastnosti bezkontaktního systému měření deformací průmyslových a inženýrských objektů zobrazovací metodou. Jsou odvozeny vztahy umožňující výpočet všech parametrů měřicího systému a na příkladě je ukázán postup výpočtu s použitím komerčně dostupných prvků.
The extraordinary advancement of the ethnological research in the twentieth century that aims to describe and explain the modalities of human existence brought also some important practical results. For example, ethnology has demonstrated the nonexistence of fundamental dijferences among the peoples of this planet and through this contributed especially to the struggle against racial theories. It also fomented a more profound study of the roots that give rise to basic consciousness of morals and of moral conduct in individual cultures. According to SigmundFreud, similarities exist in the psychic of allpeople, because we allpass through the universal experience of childhood and our life in adulthood is,for the main part, resultingfrom theprocesses oflearning and socialization in a concrete environment. The majority of things that man has to do doesn ’t stemm from the immediate experience and observation, but from the constant sifting and refming of the tradition that asks for individual acceptation and observation of moral principles which are impossible to justify through usual theories of racionalization. The Nobelprize holder, the Austrian economist Fr. A. Hayek, has stated that the selective process that had formed the cusíoms and morals, could háve responded to more factual realities then the individuals could possibly perceive, and owing to this, the tradition is “wiser ” then the human intellect. Moral attitudes and moral conduct don ’t emanate from the the books of ethics, but mainly from the traditions we were born to, and from the education that is based on these traditions. The principles of moral conduct, encoded in customs, songs, rhymes, stories and other expressions of family, national or ethnic traditions, háve a marked importance even in contemporary desacralized society, in čase we accept their historical conditionality. The current intense technical and economical processes, accompanied by the development of globál communication, influence the contacts of various cultural patterns and result in a difficult acculturation process. This could lead to the rise of a qualitatively new cultural systém, but at the same time these processes contains in themselves the inclination towards the defence of one ’s own systém and refusal of other influences, regardless of the fact that the conditions for the existence of isolated local cultures in reál cease to exist A human individual acquires his evaluative judgements through the processes of learning and experience to such extent that he comprehends the conduct that is incompatible with good morals as something impossibble. The contemporary ethnological research confirms that this is the essence o and f the ethical consciousness and conduct, albeit modified in different cultures, and that the precondition of peaceful development of the modem multicultural society is the comprehension of the sources of moral principles of the past generations.
