Lighting of interior spaces on buildings
No full textThe bachelor thesis is focused on artificial lighting of interior spaces, evaluation and comparison of electric light sources and description methods of controlling appropriate of lighting. In the first chapter the author focuses on the description of electromagnetic radiation, artificial lighting with a description of the basic quantities of lighting technology that characterize artificial light and area of lighting. He also describes the construction and parameters of electric light sources and methods of controlling stratification of lighting. In the last part, the author presents a comparison of the parameters of the electric light sources and in conclusion he proposes an algorithm of choice the light sources, based on the parameters of the area
MANAGEMENT OF INVESTMENT PROJECTS PERFORMANCE
Get PDFThis article deals with the problems of the investment projects management effi ciency. We have analyzed specifi c risks that should be considered in the course of development of performance indicators of the investment project. Approaches to solving this problem have been identified and substantiated. On the basis of the research the author offers a number of methods for evaluating the stability and effi ciency of the project, as well as the procedure of calculating the expected project outcome; the author has also formed the stages of simulation modeling, which allows estimating the possible range of effi ciency variation for different project environments

Low-Temperature Uniaxial Orientation Effect on the Structure and Piezoelectric Properties of the Vinylidene Fluoride-Tetrafluoroethylene Copolymer Films
No full textThis paper considers the uniaxial orientation effect on the structure and piezoelectric properties of vinylidene fluoride-tetrafluoroethylene copolymer ferroelectric films. The films were exposed to uniaxial orientation stretching in a temperature range from 20 °C to 60 °C; then, they were contact polarized under normal conditions. The temperature dependence of the electric strength was determined. The longitudinal piezoelectric coefficient d33 values were measured by the quasi-static Berlincourt method. The piezoresponse force microscopy (PFM) method was used to investigate the film domain structure before and after polarization, and the local piezoelectric coefficient values were also calculated. Phase composition was studied using differential scanning calorimetry and infrared spectroscopy with the Fourier transform. It was found that uniaxial orientation stretching contributed to an increase in the piezoelectric coefficient d33 from 5 pC/N to 16–20 pC/N. The results obtained indicate the importance of the amorphous phase contribution to the formation of the piezoelectric properties in polymeric materials
