A novel approach for observing band gap crossings using the SIMS technique in Pb_(1-x)Sn_(x)Te

This paper introduces a pioneering application of secondary ion mass spectrometry(SIMS)for estimating the electronic properties of Pb_(1-x)Sn_(x)Te,a compound categorized as a topological crystalline insulator.The proposed approach marks the first application of SIMS for such estimations and focuses on investigating variations in ionization probabilities and shifts in the energy distribution of secondary ions.The ionization probabilities are influenced by pivotal parameters such as the material's work function and electron affinity.The derivation of these parameters hinges upon the energy gap's positioning relative to the vacuum level for varying values of within the Pb_(1-x)Sn_(x)Te compound.The findings elucidate noteworthy alterations in SIMS signals,particularly near the critical point of band-gap closing.

Mathematical Modeling and Evaluation of Reliability Parameters Based on Survival Possibilities under Uncertain Environment

In this article,mathematical modeling for the evaluation of reliability is studied using two methods.One of the methods,is developed based on possibility theory.The performance of the reliability of the system is of prime concern.In view of this,the outcomes for the failure are required to evaluate with utmost care.In possibility theory,the reliability information data determined from decision-making experts are subjective.The samemethod is also related to the survival possibilities as against the survival probabilities.The other method is the one that is developed using the concept of approximation of closed interval including the piecewise quadratic fuzzy numbers.In this method,a decision-making expert is not sure of his/her estimates of the reliability parameters.Numerical experiments are performed to illustrate the efficiency of the suggested methods in this research.In the end,the paper is concluded with some future research directions to be explored for the proposed approach.

Analysis of the Heat Transfer Efficiency of an Automobile Engine under Different Grille Opening and Closing Conditions

Computational Fluid Dynamics is used to assess the thermal(heat transfer)performances of an automobile engine considering different grille opening and closing degrees.For this purpose the entire vehicle is modelled and three fundamental aspects are examined,namely,the open area of the air intake grille,the position of the upper and lower grilles and their shape.The results show that the opening area and position of the grille have some influence also on the aerodynamic characteristics of the automobile.With an increase in the opening angle of the grille,the CD(Drag Coefficient)value of the whole vehicle becomes higher.When the air intake grille of the car is fully open or closed,the CD value is 0.35434 or 0.31777,respectively,that is,the flow resistance in the engine compartment accounts for 10.32%of the CD value for the whole automobile.

Mother Tongue Interference in Japanese Passive Sentence Teaching —— Analysis Based on Functional Grammar

For foreign language learners, whether Chinese people are learning Japanese or Japanese learning Chinese, if they can eliminate the interference of basic knowledge of the mother tongue, the efficiency of foreign language learning will be greatly improved. This paper mainly analyzes the problem of mother tongue interference encountered by Japanese learners who use Chinese as their mother tongue in the study of "passive sentences". It focuses on introducing Japanese functional grammar on the basis of traditional grammar to eliminate these interference problems.

FUNCTION OF ADJECTIVE IN A SENTENCE

In English grammar, an adjective is used to depict, qualify or modify a noun. In doing so, it may refer to the noun either directly, or through the medium of a link verb. Take the adjective "diligent" for example. We can say, "a diligent student", or "The student is diligent." Thus,

Functional Equivalence and Translation of English Long Sentences

Since English long possess a lot of modifiers and their syntax structures are complicated, it is difficult for the Chinese readers to understand them, not to mention translating them. The paper adopts Nida's theory of functional equivalence as the guideline in the process of translation, since it bears the merit of facilitating the communication of information. In terms of concrete methods, the long sentence should be decomposed into kernel sentences and reconstructed according to the expression of the standard Chinese language. Only by doing that, the translation version can be faithful, correct and elegant.

A novel way for vibration control of FGM fluid-conveying pipes via NiTiNOL-steel wire rope

In this study,a coupling model of fluid-conveying pipes made of functionally graded materials(FGMs)with NiTiNOL-steel(NiTi-ST)for vibration absorption is investigated.The vibration responses of the FGM fluid-conveying pipe with NiTi-ST are studied by the Galerkin truncation method(GTM)and harmonic balance method(HBM).The harmonic balance solutions and the numerical results are consistent.Also,the linearized stability of the structure is determined.The effects of the structure parameters on the absorption performance are also studied.The results show that the NiTi-ST is an effective means of vibration absorption.Furthermore,in studying the effect of the NiTi-ST,a closed detached response(CDR)is first observed.It is noteworthy that the CDR may dramatically change the vibration amplitude and that the parameters of the NiTi-ST may determine the emergence or disappearance of the CDR.This vibration absorption device can be extended to offer more general vibration control in engineering applications.

The quantum spectra analysis of the circular billiards in wells

We use a recently defined quantum spectral function and apply the method of closed-orbit theory to the 2D circular billiard system. The quantum spectra contain rich information of all classical orbits connecting two arbitrary points in the well. We study the correspondence between quantum spectra and classical orbits in the circular, 1/2 circular and 1/4 circular wells using the analytic and numerical methods. We find that the peak positions in the Fourier- transformed quantum spectra match accurately with the lengths of the classical orbits. These examples show evidently that semi-classlcal method provides a bridge between quantum and classical mechanics.

On Liu Zhongde's Translation Principle in the Two Versions of Emma

This paper,based on the Eugene A. Nida' Functional Equivalence theory,tries to make a contrastive study on the two Chinese versions of Emma rendered in 80s and 90s by Liu Zhongde from the following three perspectives,that is differences on transmitting the three-character principle:faithfulness,expressiveness and closeness. Through a systematic comparison and contrast,the writer draws a conclusion that the version in 90s transcends over that one produced in 80s with a better mastery on the three-character principle which proposed by Liu Zhongde himself. In the end,the writer gives a comprehensive evaluation to the two Chinese versions in the view of translation principle,and suggests that we should learn from Liu's spirit in studying and conducting a study of Liu's thought and practice in translation as it is a treasure of Chinese translation.

Adaptive proportional integral differential control based on radial basis function neural network identification of a two-degree-of-freedom closed-chain robot

A closed-chain robot has several advantages over an open-chain robot, such as high mechanical rigidity, high payload, high precision. Accurate trajectory control of a robot is essential in practical-use. This paper presents an adaptive proportional integral differential （PID） control algorithm based on radial basis function （RBF） neural network for trajectory tracking of a two-degree-of-freedom （2-DOF） closed-chain robot. In this scheme, an RBF neural network is used to approximate the unknown nonlinear dynamics of the robot, at the same time, the PID parameters can be adjusted online and the high precision can be obtained. Simulation results show that the control algorithm accurately tracks a 2-DOF closed-chain robot trajectories. The results also indicate that the system robustness and tracking performance are superior to the classic PID method.
