Chao Yuen Ren (1892–1982)
No full textY. R. Chao is easily the most famous linguist to have come out of China. Born before the end of the last dynasty in China, he received a traditional Confucian education, but was also one of the first Chinese people to be sent to the West for training in modern Western science (under the Boxer Indemnity Fund). The remarkable breadth and scope of his studies included physics, mathematics, linguistics, musical and literary composition, and translation, and he was a pioneer in many of these fields

Uncertainty Analysis for In-situ Fan Curve Calibration in Variable Air Volume Systems
No full textIn order to obtain in-situ fan performance curves for variable air volume (VAV) air handling units (AHUs) with predicted uncertainties, airflow measurements for an extended time and a tailored calibration procedure were proposed and validated in this work.
To obtain airflow measurement for an extended time, traverse measurements through the Equal-Area method were first conducted to select 3 sampling points (3-P) that represented the average velocity at a measurement plane. Next, through statistical analysis, additional uncertainty generated when reducing the number of sampling points was accounted for in terms of sampling time, reduced number of sampling points, measurement location, and comparison to common airflow measurement stations (AFMS). As a result of these analyses, it was found that for sampling times of 60 seconds, uncertainties below 5% can be expected from 3-P measurements when airflow velocity is above 800 fpm. Analysis showed that for return air (RA) measurements where velocities below 800 fpm are common, more than 3-P would be necessary to comply with 5% accuracy per ASHRAE Standard 111 [2008] requirements.
Next, it was demonstrated through comparison of measurement conditions and uncertainties for supply air (SA) that a relationship between measurement location and uncertainty of the 3-P measurement exists. Finally, the results showed that AFMS utilized more sampling points than necessary to achieve 5% accuracy in every test case. Performing airflow measurements with a tailored selection of sampling points was more effective than following cross-sectional area-based industry guidelines.
Upon the completion of the airflow uncertainty analyses, a calibration procedure for VAV AHUs was also produced and tested to obtain in-situ fan performance curves. In addition, based on the ANSI/ASHRAE Standard 51 [1999], an uncertainty analysis was performed on adjusted measurements by fan laws to build in-situ fan performance curves. Uncertainty bands at 95% confidence showed that previously defined airflow measurement uncertainty is the most sensible variable. Results showed that while application of fan laws can be applicable to return fans (RFs), higher uncertainties can be expected as airflow velocities below 800 fpm are common. Nevertheless, since SA average velocities were generally above 800 fpm, narrow uncertainty intervals were observed.
In conclusion, a practical and reliable approach for in-situ fan performance curves calibration was explored using statistical analysis and uncertainty propagation of airflow, fan head, and fan power uncertainties. Airflow measurements for extended sampling times were successfully achieved after developing a prototype holding bracket design for reducing field technician dependency. Finally, a VAV AHU calibration procedure for obtaining in-situ fan performance curves with actual range and visible system effect impacts was successfully applied and validated through this thesis work

Magneto-optical Kerr effect in ferroelectric antiferromagnetic two-dimensional heterostructures
No full textWe study the magneto-optical Kerr effect (MOKE) of the two-dimensional
heterostructure CrI3/In2Se3/CrI3 by using density functional theory
calculations and symmetry analysis. The spontaneous polarization in the In2Se3
ferroelectric layer and the antiferromagnetic ordering in CrI3 layers break the
mirror symmetry and the timereversal symmetry, thus activating MOKE. We show
that the Kerr angle can be switched by either the polarization or the
antiferromagnetic order parameter. Our results suggest that ferroelectric and
antiferromagnetic 2D heterostructures could be exploited for ultra-compact
information storage devices, where the information is encoded by the two
ferroelectric or the two time-reversed antiferromagnetic states, and the
read-out performed optically by MOKE
A Consistent Nonparametric Test for Causality in Quantile
No full textThis paper proposes a nonparametric test of causality in quantile. Zheng (1998) has proposed an idea to reduce the problem of testing a quantile restriction to a problem of testing a particular type of mean restriction in independent data. We extend Zheng’s approach to the case of dependent data, particularly to the test of Granger causality in quantile. The proposed test statistic is shown to have a second-order degenerate U-statistic as a leading term under the null hypothesis. Using the result on the asymptotic normal distribution for a general second order degenerate U-statistics with weakly dependent data of Fan and Li (1996), we establish the asymptotic distribution of the test statistic for causality in quantile under ß-mixing (absolutely regular) process.Granger Causality, Quantile, Nonparametric Test
Developing students' awareness of Global Englishes
No full textAlthough research on Global Englishes (GE) has demonstrated the potential for a new perspective of ELT, studies of GE in an Asian ELT context are relatively rare. As current mainstream ELT practice in China still largely emphasizes 'native English', university courses related to GE are scarce. This paper aims to unpack the influence of a course on English as a World Language in Chinese university students' awareness of their own English and GE. Data were collected from students taking the optional course at a university in southeast China. After reporting the findings, the paper further discusses the pedagogical implications of integrating GE into English learning and teaching. It also argues for raising students' GE awareness and applying critical pedagogy in ELT for GE-oriented instruction.</p
