Abstract

The symbolistic poetry of Alexander Blok is connected with the thinking of both philosophers and psychoanalysts about the world and the man inscribed in it by the phenomenon of “I”. When coming into contact with transcendence, the poet crosses the demarcation line dividing the rational and irrational world, consciousness and unconsciousness. In the first period of creativity, the Russian symbolist nourishes his imagination, infl uenced by the philosophy of Vladimir Soloviev, with longing for the ideal of femininity. The driving force of the Blok’s imagination becomes, understood after Freud, the desire to meet the ideal residing in the oneiric space, and then to unite with it at the dual level (physical and spiritual). From the psychoanalytic perspective, the cycle Verses about the Beautiful Lady is both an attempt to go beyond awareness and search for the sense of a poetic image, its original source in the unconscious, as well as entering into the mirror phase described by J. Lacan. Beautiful Lady plays a role of what the French psychiatrist appoints as an objet petit a: this object is essentially unreachable and that is why it raises a great desire in the lyrical subject. The mechanism of the transition from chaos to unity, though only apparent in Blok’s works, is identical to the psycho-physical experience of the child, observing himself in the mirror.

Abstract

The paper presents major issues associated with the problem of modelling change output accelerometers. The presented solutions are based on the weighted least squares (WLS) method using transformation of the complex frequency response of the sensors. The main assumptions of the WLS method and a mathematical model of charge output accelerometers are presented in first two sections of this paper. In the next sections applying the WLS method to estimation of the accelerometer model parameters is discussed and the associated uncertainties are determined. Finally, the results of modelling a PCB357B73 charge output accelerometer are analysed in the last section of this paper. All calculations were executed using the MathCad software program. The main stages of these calculations are presented in Appendices A−E.

Abstract

The mechanical state of broken surrounding rock during the construction of ultra-shallow buried high-speed railway tunnel is very complicated, seriously affecting the construction safety. Taking Huying Xishan tunnel on Beijing-Shenyang Line as engineering background, MADIS/GTS NX numerical simulation and field test methods are used to analyze the characteristics of stress field, overall displacement, horizontal convergence of tunnel sidewalls and vault settlement during construction. The main mechanical characteristics of ultra-shallow buried high-speed railway tunnel with broken surrounding rock include: (1) After the stress redistribution, the stress concentration occurs at the boundary of the tunnel sidewall and surrounding rock, and the vertical displacement of tunnel vault and bottom appears obviously. (2) The horizontal displacement on both sides of the initial lining is obvious, while the horizontal displacement on the upper and lower support is small. The maximum lateral displacement of the initial lining is 1.71 cm, while the maximum vault settlement of the lower invert is 9.3 cm. (3) Both the horizontal convergence and the vault settlement increase with time. The growth rate is large in the early stage and tends to be stable in the later stage. (4) Compared with exponential and hyperbolic functions, the logarithmic function is most suitable for regression analysis of horizontal convergence and measured vault settlement data, and its fitting accuracy is higher than 90%.
