Rubber asphalt pavement has the performance advantages of noise reduction, anti-rutting, and anti-cracking. In this paper, the deformation recovery ability, stress sensitivity, dynamic mechanical performance, and chemical components of a warm mix styrene-butadiene-styrene (SBS)/rubber asphalt before and after aging were analyzed. The results showed that the high-low temperature performance of the asphalt was improved, and the ratio of the viscoelastic component was changed by adding the LKW-II warm mix additive to the asphalt. The high-temperature performance of the warm mix SBS/rubber asphalt was improved after short-term aging. At a proportion of the warm mix additive of 0.1%, the high-temperature rheological performance was substantially improved, the anti-rutting ability was enhanced, and the stress sensitivity was the lowest. At high temperatures, the improvements were relatively small at warm mix additive proportions of 0.3% and 0.5%. The low-temperature performance was significantly improved at a proportion of 0.3%. The Burgers model was used to evaluate the low-temperature mechanical behavior and confirmed the low-temperature performance results. The Fourier transform infrared spectroscopy results showed that no new substances were produced after adding the LKW-II warm mix additive to the SBS/rubber asphalt, and the viscosity was reduced by changing the intermolecular force. Key words: warm mix SBS/rubber asphalt, LKW-II warm mix additive, multiple stress creep recovery test, Burgers model, high-low temperature performance. Le revetement d'asphalte en caoutchouc presente les avantages de performance suivants : la reduction du bruit, l'antiornierage et l'antifissure. Dans le present document, on a analyse la capacite de recuperation de la deformation, la sensibilite aux contraintes, les performances mecaniques dynamiques et les composants chimiques d'un melange tiede de styrene-butadienestyrene (SBS) et d'asphalte en caoutchouc avant et apres le vieillissement. Les resultats ont montre que le rendement a haute et a basse temperature de l'asphalte a ete ameliore et que le rapport de la composante viscoelastique a ete modifie par l'ajout de l'additif tiede LKW-II a l'asphalte. Le rendement a haute temperature du melange tiede SBS et d'asphalte en caoutchouc a ete ameliore apres un vieillissement a court terme. A une proportion de 0,1 % de l'additif melange tiede, la performance rheologique a haute temperature a ete sensiblement amelioree, la capacite anti-ornierage a ete amelioree et la sensibilite aux contraintes a ete la plus faible. A des temperatures elevees, les ameliorations etaient relativement faibles a des proportions d'additif melange tiede de 0,3 et 0,5 %. La performance a basse temperature a ete significativement amelioree a une proportion de 0,3 %. Le modele Burgers a ete utilise pour evaluer le comportement mecanique a basse temperature et a confirme les resultats du rendement a basse temperature. Les resultats de la spectroscopie infrarouge a transformee de Fourier ont montre qu'aucune nouvelle substance n'a ete produite apres l'ajout de l'additif tiede LKW-II a l'asphalte SBS/caoutchouc, et que la viscosite a ete reduite en changeant la force intermoleculaire.

In view of the effect of random uncertain factors such as the material properties of the turning shaft and different load conditions on its performance, and reduce its weight to improve fuel economy.Through the finite element modeling of the dump truck, the load analysis of the turning shaft is carried out according to the limit force under the actual working conditions, the first-order second moment method is used for reliability analysis, and the reliability index is used to reflect the influence of uncertain factors. The stiffness and dynamic characteristic values under static multi-conditions are set as objective functions, and the volume fraction and reliability index are used as constraints. A comprehensive objective function is established based on the normalized sub-objectives of the compromise programming method, the weight coefficients of the sub-objectives are determined by the analytic hierarchy process, and the multi-objective topology optimization design based on reliability constraints is carried out on the flip-axis structure. The results show that, compared with the deterministic topology optimization, the stiffness of the turning axis and the natural frequencies of each order obtained by the reliability topology optimization are more significantly improved, and the mass is reduced by 28.96% under the condition of satisfying the reliability. The experimental test and theoretical analysis results are basically consistent, verifying the feasibility of multi-objective reliability topology optimization design.

Journey to the West (西游记; Xi You Ji) is one of the best-known classic novels in Chinese literature, and it has been translated into English by various notable translators. This study compares the retranslation of the novel by Julia Lovell published in "Penguin Classics" in 2021 with Arthur Waley's translation in "Penguin Classics" in 1973. Employing a stylometric approach to compare the styles of the two translations, it uses the corpus tools of word lists, keyword analysis, and function word analysis. The results reveal distinct stylistic differences in the translators' styles, including lexical density, sentence length, and function words, which point to different translation strategies employed by the two translations of this classic Chinese novel. The book reviews published so far indicate that Lovell's version has been well received by contemporary Anglophone readers and that the changes in this retranslation may have helped to explain the recanonization of the original classic. This study provides new insights into the understanding of the differences between translation and retranslation, and thus has implications for the fields of translator style studies and stylometry research.

Fluency is an important yet difficult-to-measure criterion in interpreting assessment. This empirical study of English-Chinese consecutive interpreting aims to identify fluency parameters for a machine-learning-based automated assessment system. The main findings include: (a) empirical evidence supports the choice of the median values as the cut-offs for unfilled pauses and articulation rate; (b) it informs the selection of outliers as particularly long unfilled pauses, relatively long unfilled pauses, particularly slow articulation and relatively slow articulation; (c) number of filled pauses, number of unfilled pauses, number of relatively slow articulation, mean length of unfilled pauses, mean length of filled pauses can be chosen to build machine-learning models to predict interpreting fluency in future studies as they can explain the variance of established temporal measures and show stronger explanatory power than dependent variables when predicting scores. The study identifies assessment rubrics on an empirical basis and provides a methodological solution to automate the labour-intensive tasks in interpreting assessments. [ABSTRACT FROM AUTHOR]

In order to quantitatively analyze characteristics of the hinge joint loads under actual working conditions,and provide basis for compiling the load spectrum of key components,a medium-sized excavator XE215 G was taken as the research object,whose hinge joint loads was obtained by two methods. The first is using the three-dimensional pin-shaft force sensor to measure the positive load,lateral load and offset load at the hinge joint of stick and bucket,and using the link rod force sensor to measure the link rod force,and then the other hinge joint loads could be calculated by the mechanical equilibrium equation; The second is using the measured pressure and displacement of the boom cylinder,stick cylinder and bucket cylinder to calculate all hinge loads indirectly by a kinetic model. Simultaneously,the stress-time histories of the large stress measure points on the boom and the stick were recorded. The hinge joint loads obtained by the two methods were in good agreement with each other,indicating that the test is reliable. For method 1,the relative deviations of fatigue damage of each measure point between including and excluding lateral load and offset load is less than 6. 98%,except for a measure point whose fatigue damage is obviously smaller than other points,which indicates that the lateral load and the offset load have little effect on fatigue damage. For method 2,the calculated stress of each measure point obtained by the load-stress transfer coefficient was compared with the measured stress of the corresponding point. The results show that they are in good agreement with each other and the most relative deviation between the calculated damage and the actual damage is 8. 33%,which indicates that the hinge load obtained from the method 2 can reproduce the stress and damage of each measuring point well. Under normal working conditions,the hinge joint load of theexcavator working device can ignore the lateral load and offset load approximately,while can be obtained by the simple and feasible method of measuring the cylinder pressures and displacements.
