A Tentative Analysis of English Film Translation Characteristics and Principles
Yan Chang
Theory and Practice in Language Studies , 2012, DOI: 10.4304/tpls.2.1.71-76
Abstract: Film is a kind of audio-visual art, where dialogues work together with visual images, sound tracks and music. Film translation, as a kind of mass multimedia translation, is a new field of art and translation. Based on detailed analysis of the characteristics of film translation compared with general translation, two prevalent methods of film translation: dubbing and subtitling, and the constraints of each method, this paper attempts to categorize some feasible principles and requirements that account for successful film translation, which can be used to guide film translation practice.
Optimized Algorithm for Clustering Routing for Wireless Sensor Networks  [PDF]
Tieyuan Chang, Weina Liu, Yan Zhang
Journal of Computer and Communications (JCC) , 2018, DOI: 10.4236/jcc.2018.611001
Abstract: LEACH protocol randomly selects cluster head nodes in a cyclic manner. It may cause network to be unstable, if the low energy node is elected as the cluster head. If the size of cluster is too large or too small, it will affect the survival time of the network. To address this issue, an improved solution was proposed. Firstly, the scheme considered the average and standard deviation of the nodes’ residual energy and the distance between the node and the base station, then considered the distance between the node and the cluster head and the energy of the cluster head to optimize the cluster head selection and clustering. The performance analysis results showed this scheme could reduce premature deaths of the cluster heads and too high energy consumption of some clusters. Thus, the proposed algorithm could prompt the stability and prolong the lifetime of the network.

Chang-jun Zheng, Zhou Yan, Li Wei
Journal of Service Science and Management (JSSM) , 2008, DOI: 10.4236/jssm.2008.12018
Abstract: With the development of reform of stock system among Chinese commercial banks, more and more listed banks are coming forth to the market, so it is important to analyze the relationship between the equity structure and its perform-ance of Chinese listed bank. For representatives, this article selected 6 banks from the total of 14 listed banks, and then made the demonstration analysis about the relationship between the performance and equity structure, according to their different equity structures. The result shows the first major shareholder is significantly relative to banks’ perform-ance, by contract, there’s no notable correlation between the big five /ten and bank’s performance, but square sum of equity by the ten big is correlate to the performance.
Optical Microstructure Design Optimization for Display Backlighting  [PDF]
Chi-Chang Hsieh, Yan-Huei Li
Modern Mechanical Engineering (MME) , 2013, DOI: 10.4236/mme.2013.34027

This study proposes an innovative design method for functional optical film microstructures used in displays and applies this design to LCD backlighting to replace multi-layer optical film functional integration with composite optical film. We design a novel optical film microstructure based on light uniformity and wide-angle lumination distribution and determine the optimal optical microstructure parameters by combining the global optimization of a genetic algorithm with ray tracing. The purpose of this study is to develop substitutes for traditional multi-layer prism brightness enhancers and light-diffusing film stacks and to examine the structural changes during calculations and summarize the characteristics. In this study, we focus on determining the optimal light uniformity of new optical film microstructures. The seven-inch LED backlight module of the method proposed in this study achieved 94.59% uniformity and 168° lumination distribution while reducing thickness by 66% to 82% compared to a traditional multi-layer optical film stack.

Open Journal of Fluid Dynamics (OJFD) , 2017, DOI: 10.4236/ojfd.2017.73029
Plate heat exchanger can obtain higher thermal performance because of its advantages in high heat transfer coefficient, small scale, and can realize pure counter current flow. It has been widely applied in HVAC industry. In this paper, the numerical research of plate heat exchanger in solar heating system has been proposed. Aimed at the type of herringbone corrugated plate which has better thermal performance and been widely used, the three dimensional model is established by Gambit software. Using FLUENT software for numerical calculation, by studying the effect of corrugated inclination angle, corrugated depth, corrugated spacing and inlet velocity of heat exchanger on internal temperature, pressure, velocity distributions of domains, the relationship between the above parameters and the Nusselt Number and the pressure drop was obtained by simulation data. Heat transfer coefficient and pressure drop correlations used to measure the overall performance of the heat exchanger. The result shows that the optimal structure parameters is corrugated angle 60°, corrugated depth 4 mm and corrugated spacing 16 mm.

Abstract: Sox8 gene is one of important transcription factors in developments of many tissues and organs. In this article, The Sox genes of P. dabryanus were amplified by degenerate primers within HMG-box. Three amplification bands with the length 220,550 and 1500bp respectively were observed in all individuals. A novel gene fragment was obtained from the 550bp band. It coded 53 amino acid residues, the other part of the fragment may be a intron. The identity of possible amino acid sequence to mouse Sox8, 9 and SRY is 96%, 94%, and 47% respectively. The identity to human SOX8, 9 and SRY is 64%, 94%, and 40% respectively. So, it was named PdSox8. Northern blotting result showed that it overexpresses in adult liver and brain.
BCS-BEC crossover of Spin Polarized Fermi Gases with Rashba Spin-Orbit Coupling
Chang-Yan Wang,Yan He
Physics , 2015,
Abstract: We study the BCS-Bose Einstein Condensation (BEC) crossover of a three dimensional spin polarized Fermi gas with Rashba spin-orbital-coupling (SOC). At finite temperature, the effects of non-condensed pairs due to the thermal excitation are considered based on the $G_0G$ pair fluctuation theory. These fluctuations generate a pseudogap even persistent above $T_c$. Within this framework, the Sarma state or the spin polarized superfluid state and polarized pseudogap state are explored in detail. The resulting $T_c$ curves show that the enhancement of pairing due to the SOC roughly cancels out the suppression of pairing due to the population imbalance. Thus we observed that in a large portion of the parameter space, the polarized superfluid state are stabilized by the SOC.
The $Z_2$ Classification of Dimensional Reduced Hopf Insulators
Chang-Yan Wang,Yan He
Physics , 2014, DOI: 10.1088/0953-8984/27/7/075603
Abstract: The Hopf insulators are characterized by a topological invariant called Hopf index which classifies maps from three-sphere to two-sphere, instead of a Chern number or a Chern parity. In contrast to topological insulator, the Hopf insulator is not protected by any kind of symmetry. By dimensional reduction, we argue that there exists a new type of $\mathbb{Z}_2$ index for 2D Hamiltonian with vanishing Chern number. Specific model Hamiltonian with this nontrivial $\mathbb{Z}_2$ index is constructed. We also numerically calculate the topological protected edge modes of this dimensional reduced Hopf insulator and show that they are consistent with the $\mathbb{Z}_2$ classification.
The electrical parameters measurement system for electrotome output based on Labview  [PDF]
Shengjie Yan, Yu Zhou, Bowen Yan, Dianli Li, Chengli Song, Zhaohua Chang
Journal of Biomedical Science and Engineering (JBiSE) , 2013, DOI: 10.4236/jbise.2013.66081

An accurate detection of the effective values of electric voltage and current from high frequency power generators is a precondition for the development of smart electrotomes. In this light, an energy detection system based on personal computer (PC) is developed hereby. It senses voltage and current in isolation from generators with transformers, and then the measured values are amplified, filtered, transformed into single-ended signals and converted to RMS. The detected signals are transformed into digital signals through Data Acquisition Card (DAQ) and the data are processed with quadratic fit in Labview. Finally, the controller completes constant power output. The experiment results indicate that the energy detection system can measure the output parameters precisely and the controller can achieve constant power control.
