Globalization has integrated the world through interaction among countries and people with the help of information and telecommunication technology (ICT). The rapid mode of globalization has put a new life in ICT and economic sector. The key focus of this study is to examine the nexus among the globalization, ICT and economic growth. This study uses autoregressive distributed lag model (ARDL), vector error correction model (VECM) and econometric method spanning from 1990 to 2015. The empirical result highlights that the globalization stimulates economic growth of a country. In addition, both the internet penetration and the mobile phone usage contribute to the economic growth. Lastly, this article contributes important policy lessons on strengthening the economy by utilizing ICT with the rapid globalization.

Ximei Liu,Zahid Latif,Daoqi Xiong,Sehrish Khan Saddozai,Kaif Ul Wara 한국정보처리학회 2019 Journal of information processing systems Vol.15 No.5

Stock price is characterized as being mutable, non-linear and stochastic. These key characteristics are known tohave a direct influence on the stock markets globally. Given that the stock price data often contain both linearand non-linear patterns, no single model can be adequate in modelling and predicting time series data. Theautoregressive integrated moving average (ARIMA) model cannot deal with non-linear relationships, however,it provides an accurate and effective way to process autocorrelation and non-stationary data in time seriesforecasting. On the other hand, the neural network provides an effective prediction of non-linear sequences. Asa result, in this study, we used a hybrid ARIMA and neural network model to forecast the monthly closing priceof the Shanghai composite index and Shenzhen component index.

Average Consensus of Multi-agent System With Binary-valued Observations

Ximei Wang,Ting Wang,Changbao Xu,Yanlong Zhao 제어로봇시스템학회 2015 제어로봇시스템학회 국제학술대회 논문집 Vol.2015 No.10

This paper considers average consensus problem of a multi-agent system with binary-valued observations. The information network transfers binary-valued information and the control is a quantity of transportation between neighbors. We propose a two-scale average consensus algorithm with a constant gain and prove the convergence and convergence rate of the algorithm. In the first stage, each agent estimates the states of its neighbours based on binary-valued observations for a holding time. In the second stage, the system updates the states of agents by a control law which is designed as a quantity of transportation between neighbors with a constant gain. The algorithm is proved to be convergent and asymptotically efficient, meanwhile, the renewal of agents can lead to average consensus. Finally, simulations illustrate the effectiveness of the obtained results.

Stability of Reticulated Shell with Steel Panel as the Bracing and Time-varying Structure for LNG Tank During Concrete Dome Casting

Ximei Zhai,Yonghui Wang,Heng Wang 한국강구조학회 2017 International Journal of Steel Structures Vol.17 No.3

With the growing demand of energy for recent decades, liquefied natural gas (LNG) has become one of the most significant energy sources due to the high calorific value and performances, as well as the ease of transportation and storage. Hence, many LNG tanks have been constructed to store liquefied nature gas and the roof of a LNG tank consists of reticulated shell, roof panel and concrete dome. The ribbed-type reticulated shell welded to the roof panel, which is called roof panel enhanced (RPE) reticulated shell in this paper, can be treated as the template during concrete dome casting. In addition, it also sustains the gravity load of concrete dome before concrete hardening and works together with concrete dome as a composite structure after concrete hardening. It is of significance to study the response of RPE reticulated shell during the construction stage. In the first part of this paper, the nonlinear load–deflection complete process analysis was carried out to study the buckling behavior of the RPE reticulated shell under uniformly distributed load. The effects of beam section size, rise-to-span ratio and the initial geometric imperfection magnitude on the buckling resistance of the RPE reticulated shell were investigated to optimize the current design. In the second part of this paper, the buckling behavior of the RPE reticulated shell under non-uniformly distributed load induced by concrete dome casting was studied and the air pressures of each construction step were determined by considering the response behaviors of the time-varying structures composed of RPE reticulated shell, concrete dome and changing load. The safety factors of the RPE reticulated shell were calculated under the appropriate air pressure and initial geometric imperfections, based on which, the original optimized design of the RPE reticulated shell was improved to reduce the material consumption.

LIU XiMei,WANG ChangFeng,Shahid Rasheed,Muhammad Nawaz Tunio 보안공학연구지원센터 2016 International Journal of u- and e- Service, Scienc Vol.9 No.12

Oil, hailed as modern industrial blood, is of greater significance to a state, and is closely related to people's lives. Shadow price of the oil industry is a key evaluation parameter for the business of an economy. In this paper, the application of input-output method and linear programming theory has been sought to establish an optimization model for the oil industry and the shadow price of the oil industry has been calculated according to the 2007 China input-output table. The analysis concludes that among the agriculture, the industry, and the tertiary industry, the prices of oil industry products bear maximum influence on the prices of agricultural products.

Novel Load Disturbance Observer-based Global Complementary Sliding Mode Control for a Precision Motion Stage Driven by PMLSM

Hongyan Jin,Ximei Zhao,TianheWang 제어·로봇·시스템학회 2021 International Journal of Control, Automation, and Vol.19 No.11

In this paper, a novel load disturbance observer-based global complementary sliding mode control (NLDOB-GCSMC) method is proposed to achieve high servo performance of the precision motion stage driven by a permanent magnet linear synchronous motor (PMLSM). The global complementary sliding mode control (GCSMC) method incorporates an approach angle into the saturation function to realize the dynamic change of the boundary layer, which guarantees the asymptotic stability and improves the global robustness of the system. Besides, compared to hybrid CSMC strategies, the GCSMC method has a simpler structure and faster response speed. However, in practical applications, the load disturbance has a significant impact on system performance. Therefore, a novel load disturbance observer (NLDOB) capable of identifying the load variation is proposed. According to the model reference adaptive identification (MRAI) theory, NLDOB can identify the load disturbance on-line and realize compensation to further improve the robustness. The more accurate tracking performance and stronger robustness of the proposed control scheme compared to conventional approaches have been confirmed through comparative experimental studies.
