The article describes the method of abstract modelling of architectural plasticity. It includes the identification of its general compositional principles and artistic characteristics, united by the concepts of “natural” and “free” and correlated with the stylistic systems of modernism and postmodernism. The demonstration of how various electrical lighting techniques influence the architecture perception is also provided. The authors of this paper reveal peculiarities of the operation of lighting parameters and optical effects in relation to each type of model, including the interaction of external and internal spaces. They also formulate principles of creating dramaturgy and scenario of lighting solutions, and test methods of assessing the emotional perception of illuminated objects. The methodological material presented in this article provides the solution of such tasks as: the perception of architecture as an integral composition, acquaintance with the features of architectural plasticity of different times, the role of light in the perception of an architectural object, the evolution of the use of lighting techniques as a material for creating a work of art. It also describes how some masters work with electrical lighting and daylighting, as well what methods they use to create the dramaturgy of electrical light in experimental lighting solutions and to assess the emotional perception of objects under electrical lighting. The presented methodological approach allows the student to form a professional skill of working with lighting objects and spaces based on the formative properties of composition construction. This, in its turn, increases the quality of designing the architectural environment and reproducing its artistic features by means of electrical lighting.

The article describes the technical characteristics of the software-controlled power supply system for generation of second-long light pulses by means of INP‑16/580 xenon flash lamps. The amplitude-time characteristics of luminous emission in a quasi-arc mode of lamp operation are formed by computer control of temporal current pulse shape in case of large energy deposition overloads. Methods of optimisation of light and engineering characteristics were defined accounting for non-linearity of the load of the thyristor unit and ambiguity of the dependence of luminous radiation on discharge current. The data on maximum acceptable operation parameters of pulse lamps with mains supply and natural air cooling and the results of physical modelling of radiation pulses with complex shape are presented.

The analysis of the social and communicative conditions of maturation of young children actualizes the need for them to develop a special kind of personal qualities in the course of education, formed as a result of acquiring the ability to "think mathematically". The problem of teaching a growing personality to apply mathematical content to solving a wide range of problems is considered in the context of putting forward a new paradigm of the quality of education. According to it, the effectiveness of the functioning of the education system is established in accordance with the change of educational guidelines "From knowledge, skills, skills - to functional literacy". The practical solution to the problem of improving the quality of education, considered from the perspective of the formation of functional literacy, is due to the development of positive behavioral strategies in students in various life problem situations, the resolution of which can occur in the absence of a fully deterministic solution. The current stage of development of education encourages teachers in their professional activities to proceed from the targeted development of the students of the educational system of skills that allow them to resolve emerging problem situations on the basis of the functional literacy formed in the course of conducting an initiative research search. The problem of developing such skills is relevant at all stages of the educational development of a growing personality. The readiness of preschool teachers to develop functional mathematical literacy in their pupils deserves close attention from the system of additional professional education of teachers. The phenomenon of the lack of special developments aimed at implementing the strategy of education development on the basis of the designated paradigm directs the study to the problem of developing competently oriented tasks for the formation of functional mathematical literacy in pre-school students.
