An iterative computation method for interpreting and extending an analytical battery model

Battery models are of great importance to develop portable computing systems, for whether the design of low power hardware architecture or the design of battery-aware scheduling policies. In this paper, we present a physically justified iterative computing method to illustrate the discharge, recovery and charge process of Li/Li-ion batteries. The discharge and recovery processes correspond well to an existing accurate analytical battery model： R-V-W＇s analytical model, and thus interpret this model algorithmically. Our method can also extend R-V-W＇s model easily to accommodate the charge process, The work will help the system designers to grasp the characteristics of R-V-W＇s battery model and also, enable to predict the battery behavior in the charge process in a uniform way as the discharge process and the recovery process. Experiments are performed to show the accuracy of the extended model by comparing the predicted charge times with those derived from the DUALFOIL simulations. Various profiles with different combinations of battery modes were tested, The experimental results show that the extended battery model preserves high accuracy in predicting the charge behavior.

介观超导环中的电荷分布

The charge distribution in thin mesoscopic superconducting ring is studied by the phenomenological GinzburgLandau theory. In the giant vortex states we find that the mesoscopic rings may present three kinds of charge distribution while the disk only owns the first two kinds. The charge near the inner radius may change its sign from negative to positive with increasing applied field. In the multivortex state we find that there exist saddle-point states and stable multivortex states. The distribution of charge and the superconducting electron density in the （0：2） saddle states and the （0：4）, and （1：5） stable multivortex states has also been studied. The contour plot of the charge distribution and the Cooper pair density distribution are given.     

Peanut-Like Hematite Prepared by a New Facile Hydrothermal Process for Removal of As(V)

Peanut-like hematite has been prepared by a new facile hydrothermal method and applied in the adsorption removal of As(V). The structural features of the as-prepared hematite were characterized systematically by X-ray diffraction, X-ray photoelectron spectroscopy, Brunauer–Emmett–Teller, scanning electron microscopy, energy-dispersive X-ray spectroscopy mapping, Fourier transform infrared spectroscopy, and transmission electron microscopy. Results showed that the morphologies of hematite could be tuned to spindle-like, oval-like, and cantaloupe-like shapes by adjusting the hydrothermal conditions. The peanut-like hematite formation followed a five-step route. At pH = 3, the adsorption amount of As(V) over peanut-like hematite reached 13.84 mg/g, and the adsorption kinetic process corresponded to the pseudo-second-order kinetic model. The peanut-like hematite also showed partial selectivity over As(V) in the hydrosphere. This method can be a reference for the preparation of other architectural metal oxide materials.     

The Imagined Other——Image of China in Kubla Khan

Said’s Orientalism points out that the Occident is the interpreter and the Orient is the interpreted. The Occident has the privilege to interpret at will the history, culture, character and tradition of the Orient, in which the Occident finds its legitimate excuse in dominating and seizing the Orient. The paper presents an analysis of Coleridge’s Kubla Khan in which China has been constructed as the ’Other’. In addition, it also demonstrates that cultural hegemony participates in the process of colonizing the world.     

Empirical Studies on the Community＇s Education for the Aged ——Investigations to the 12 Cities

The text discusses the problem of form of organization and security system of old-age education in community from theoretical and practical aspects. From the practical analysis, we find that the main form of old-age education in community is school education. The statistics of the research shows that the level of old-age education in community is in primary stage. The teaching form, the teaching content, the mechanism of organization, and fundamental facilities need to be strengthened. The analysis in different areas shows that the teaching activities and fundamental facilities of old-age school in eastern cities are obviously better than that of cities in middle region. In theoretical analysis, it expounds the relationship between old-age education and the education in communities, old-age education and life long education. And it also raises the problem of the confusion of definition in the studying course of the old-age education＇s theories such as attribution, characteristic, and definition. Its content has been renewed. The theoretical framework has been raised in the research of security system.

Evaluation of the teaching guide as an instrument for adaptation to the new European credit system： Case analysis

This paper presents the evaluation of the teaching guide application for the subject of management control in the Business Management and Administration Degree. The evaluation began with the analysis of a questionnaire which aimed to collect the perceptions of learners who have studied this subject in two groups （morning and afternoon） during the first semester of the current academic year. The intention of this analysis was to obtain information that would meet two objectives： to continue upgrading the teaching-learning process and to revise and improve all the components in the teaching guide. There is an analysis of the degree of difficulty involved in the activities proposed and the degree to which specific objectives for different competencies have been attained. Likewise, we have carried out a global assessment of the different methodologies applied in the teaching-learning process, and an assessment of the evaluation system as well as of other aspects that could have hindered reaching the objectives stated in the guide. Furthermore, the relevance of this questionnaire has been vindicated for obtaining the information necessary to adjust the learner＇s workload to the European credit.     

Exothermic process of cast-in-place pile foundation and its thermal agitation of the frozen ground under a long dry bridge on the Qinghai-Tibet Railway

A number of dry bridges have been built to substitute for the roadbed on the Qinghai-Tibet Railway, China. The aim of this study was to investigate the exothermic process of cast-in-place （CIP） pile foundation of a dry bridge and its harm to the stability of nearby frozen ground. We present 3D heat conduction functions of a concrete pile and of frozen ground with related boundaries. Our analysis is based on the theory of heat conduction and the exponent law describing the adiabatic temperature rise caused by hydration heat. Results under continuous and initial conditions were combined to establish a finite element model of a CIP pile-frozen ground system for a dry bridge under actual field conditions in cold regions. Numerical results indicated that the process could effectively simulate the exothermic process of CIP pile foundation. Thermal disturbance to frozen ground under a long dry bridge caused by the casting temperature and hydration heat of CIP piles was substantial and long-lasting. The simulated thermal analysis results agreed with field measurements and some significant rules relating to the problem were deduced and conclusions reached.

New design of sense amplifier for EEPROM memory

We present a new sense amplifier circuit for EEPROM memory. The topology of the sense amplifier uses a voltage sensing method, having low cost and low power consumption as well as high reliability. The sense amplifier was implemented in an EEPROM realized with an SMIC 0.35-μm 2P3M CMOS embedded EEPROM process. Under the condition that the power supply is 3.3 V, simulation results showed that the charge time is 35 ns in the proposed sense amplifier, and that the maximum average current consumption during the read period is 40 μA. The novel topology allows the circuit to function with power supplies as low as 1.4 V. The sense amplifier has been implemented in 2-kb EEPROM memory for RFID tag IC applications, and has a silicon area of only 240 μm^2.     

Performance of Methanol-to-Olefins Catalytic Reactions by the Addition of PEG in the Synthesis of SAPO-34

SAPO-34, a silicoaluminophosphate zeolite, has been synthesized by the hydrothermal method with the addition of different molecular weights of polyethylene glycol(PEG), and has been characterized with XRD, SEM,N_2 adsorption–desorption, FT-IR, and NH_3 temperatureprogrammed desorption(NH_3-TPD). We studied SAPO-34 as a catalyst in the methanol-to-olefins(MTO) reaction, in a fixed-bed reactor. The results show that the chain length of PEG has a great influence on the particle size and morphology of SAPO-34. PEG acts as inhibitor in the crystallization process. With the increase of the chain length of PEG used in the synthesis, from a relative molecular weight of 400-6000, the morphology of SAPO-34 changes gradually from cubic to nanoplate-like and then changes to cubic again. The particle size decreases markedly at first and then increases to some extent. The catalytic stability in the MTO reaction also increases first and then decreases, with all the catalysts having almost the same selectivity to olefins. When the sample is synthesized with PEG800, the particles become nanoplate-like with a thickness of 46 nm on average, and the catalytic stability is appreciably prolonged, which is attributed to the shorter diffusion paths of the reactants in the zeolite.

Distinct Element Modelling of Unreinforced Masonry Wall Under Seismic Loads with and without Cable Retrofitting

To retrofit and strengthen existing unreinforced masonry (URM) structures to resist the potential earthquake damages has become an important issue in Australia. In order to secure the performance of URM under seismic loading in the future, a research project was carried out aimed at developing a simple and high strength seismic retrofitting technique for masonry structures. A series of experimental testing on URM walls retrofitted with an innovative technique by cable system have been conducted. The results indicated that both the strength and ductility of the tested speci-mens were significantly enhanced with the technique. An analytical model which is based on Dis-tinct Element Method (DEM) has also been developed to simulate the behaviour of URM walls be-fore and after retrofitting. The model is then further developed by applying a seismic wave to the wall to simulate the wall behavior under earthquake loads before and after retrofitting.     

Oxidation Characteristics of the Reactivity Between Pyrite and Aqueous Arsenate

Natural pyrites contain high levels of adsorbed and structurally incorporated arsenic(As),which may simultaneously result in the release of As and affect the oxidation process of pyrite.However,the oxidation and electrochemical behaviors of As on the oxidation reactivity of pyrites are still not clear.In this study,pyrite was prepared by a hydrothermal method and applied to study the oxidation mechanism between pyrite and aqueous arsenate.Analyses of X-ray diffraction,X-ray photoelectron spectroscopy,and scanning electron microscopy demonstrate that the as-prepared sample is an octahedron-like pyrite with high purity and crystallinity.The interaction between As(V)and pyrite as well as the electrochemical behaviors of pyrite oxidation in the presence of aqueous arsenate were investigated under acidic conditions by an ion analysis method,cyclic voltammetry(CV),Tafel,and electrochemical impedance spectroscopy(EIS).The results of the chemical reaction indicate that electrons are transferred from S _2~(2-)to dissolved oxygen with the formation of SO _4~(2-)in the initial As(V)concentration range of 0–0.3 mmol/L.In the initial As(V)concentration range of 0.4–1.2 mmol/L,electrons are transferred from S _2~(2-)to As(V)with the formation of elemental S ~(0 )and As(III).The CV,the Tafel plot and EIS analyses indicate that aqueous arsenate in an electrolyte promotes oxidation reactivity and passivation of the pyrite electrode.Moreover,the electron transfer rate increases with increasing aqueous arsenate concentration in the electrolyte.     

The Spread of English as a Global Language and its Implication for Classroom Teaching in China Context

The status of English in today’s world has been established definitely.It is not only embodied in the increasing numbers of speakers,but also embodied in the role which English has played in some non-English speaking countries.English is spread as an International language in worldwide and which is no longer belonging to any English speaking countries but belonging to those who use it(McKay,2002).The consequences of English spreading are:on one hand,English as an international lingua franca status has been further consolidated;on the other hand,different regional variants appear in English.These changes lead to the debate between Standard English and varieties of English.All of these in turn generate a profound impact on English language teaching.China as one of non-English speaking countries has also been the impact of globalization in English.The English teaching in China is facing challenges and innovation.     

Two-order Hermite vector-interpolating subdivision schemes

INTRODUCTION Along with the great progress in 3D data meas- urement device and the popularization of complex solid modelling, recursive subdivision has been a research focus in CAGD and CG (Wang et al., 2001). However, most interpolating subdivision schemes are Lagrange-type schemes whose smoothness is not easily verified. The geometric features of this kind of subdivided curves and surfaces are difficult to be generated, which restricts the application of subdivi- sion methods. From a…
