Design and Research of High Precision Dynamic Torque Measurement System

In this paper, through the FPGA technology and torque measurement system design method for analysis and research, through the use of photoelectric coding circurling measurement function and the difference between the multi-channel code disk torque measurement. In this paper, the characteristics and state of the output signal of the multi-channel code tray are classified, and the principle of torque measurement is analyzed and studied. In this paper, the logic control, data statistics, latch and other contents involved in hardware FPGA technology are analyzed and studied, so as to effectively simplify the system circuit. When the counting data, status signal and other contents are uploaded to the master computer for processing, it is convenient to monitor the vibration of torque signal in real time. By using the upper computer part of the virtual instrument to receive the relevant data of the microcontroller, so as to store, call and process the data, it not only improves the intelligence of the system, but also reduces the use cost of hardware resources.

DEVELOPMENT OF 3D PIN-BY-PIN CORE SOLVER TORTIN AND COUPLING WITH THERMAL-HYDRAULICS

Currently, safety analyses mostly rely on codes which solve both the neutronics and the thermal-hydraulics with assembly-wise nodes resolution as multiphysics heterogeneous transport solvers are still too time and memory expensive. The pin-by-pin homogenized codes can be seen as a bridge between the heterogeneous codes and the traditional nodal assembly-wise calculations. In this work, the pin-by-pin simplified transport solver Tortin has been coupled with a sub-channel code COBRA-TF. The verification of the 3D solver of Tortin is presented at first, showing very good agreement in terms of axial and radial power profile with the Monte Carlo code SERPENT for a small minicore and with the state-of-the-art nodal code SIMULATE5 for a quarter core without feedback. Then the results of Tortin+COBRA-TF are compared with SIMULATE5 for one assembly problem with feedback. The axial profiles of power and moderator temperature show good agreement, while the fuel temperature differ by up to 40 K. This is caused mainly by different gap and fuel conductance parameters used in COBRA-TF and in SIMULATE5.

Reproducing Meaning: A Dialogic Approach to Sports and Semiotics

The wide variety of the components of signs stems from verbal communication to visual gestures, ciphers, images, music, and Morse code. Barthes’ Semiotic Theory restructured the theory of analyzing signs and allowed for a new understanding and interpretation of signs through seeing diverse cultures and societies. Saussure’s definition of the sign as a combination of signifier and signified led Barthes to further elucidate sign as connotative (cultural) and denotative (literal) processes. Semiotics can be applied to all aspects of life, as meaning is produced not in isolation but in totality, establishing multiple connotations and denotations. In the article “The World of Wrestling” published in Mythologies (1957), Barthes focused on images portrayed by the wrestler resulting in understanding of the wrestler’s image and the image of spectator. In Morse code, gestures can make any sport a spectacle of suffering, defeat and justice, representation of morality, symbols, anger, smile, passion etc., from which derive denotative and connotative meanings. Similarly, Thomas Sebeok identifies sign as one of six factors in communication, and which makes up the rich domain of semiotic research. These are message, source, destination, channel, code, and context. The present paper will focus on a dialogic relation between semiotics and sports, thus making it a text that reproduces meaning and represents certain groups. It focuses on various aspects of semiotics and their relation to sports. The paper also contemplates the versions and meanings of signs in sports that establish sport as an act of representation.
