About the Role of the Hidden Text Equivalents in the Editions of the Poem “The Demon” by Mikhail Lermontov

The publication examines the role of the hidden text equivalents in the editions of the poem “The Demon” at the figurative, thematic, plot, compositional levels. In the editions of the poem “The Demon” by Lermontov there are various equivalents of the text: unrealized, unclaimed, having a variable character, replaced by previous and subsequent options, hidden. The listed types of text equivalents not only testify to the graphic features of Lermontov's verse, but also make it possible to identify encrypted information demonstrating the nature of the author's work in the poem, to emphasize their special productive role, indicating how “The Demon” gradually changed, how over time it turned from a romantic poem into a poetic story. This type of the text equivalents allows to emphasize the meaning of the fallen angel and the devil in love themes, the images of the main character, Tamara and the prince, to show how the plot of the poem gradually changed, to demonstrate the mirror structure of the composition, in particular, due to the motives of waiting, the kiss, death, the hand.

Design and Thermal Stability Analysis of Swing Micro-Mirror Structure for Gravitational Wave Observatory in Space

A kind of swing micro-mirror structure with high stability for gravitational wave observatory in space is proposed in this paper. As the key interface instrument in the gravitational wave observatory, the swing micro-mirror structure plays a very important role. Firstly, the 3D model of the mechanism is designed and established. Then, the solution method of the index of stability, pointing jitter, is researched. After that, the thermal stability and the first-order natural frequency of the mechanism are researched via finite element analysis. The first-order natural frequency of the mechanism is 247.55 Hz, which can meet the requirements of the design. It can be seen from the results of the simulation, the amplitude spectral density of the mirror angle deviation is 3.975 nrad/√Hz when the range of temperature variation is 0.1 °C, which is able to meet the requirements of the design. The thermal stability has a closed relationship with the structural stability around the X-axis. In addition, this article also studies the thermal stability of the mechanism in the case of temperature changes in different directions. It is found that the thermal stability of the mechanism around the Y-axis would be significantly affected by the temperature changes along the Y-axis.

REFLECTO – A SMART MIRROR STRUCTURE WITH A CONTEXTUAL ASSOCIATION OF INTERNET OF THINGS

Two of the most valued qualities in the modern-day society are punctuality and presentation. The mission helps to develop the above-mentioned personalities. We have developed an artificial intelligence-based smart mirror that helps in reminding the user about their day to day schedule while they spend their time in front of the mirror. This way the user is ensured of comfort in accessing the basic services with a minimum hinderance. The basic function that our prototype is assumed to carry out is to display user their personalised information like date, time, weather forecast, upcoming holidays or saved events and news bulletin. Face recognition feature is also added in order to identify the user using the camera placed behind the mirror. Because of the face recognition feature the mirror will be able to display personalised data that the identified user wants to know. Reflecto can be easily built by using a two-way mirror, concealed LED screen, microphone and camera to make it interactive. The mirror’s functionalities have been extended by integrating it with Google assistant to access IoT devices that have been enabled with home automation.
