Statistical measurements of fast changing electromagnetic fields
The present works aims at describing important statistical indexes such as the field uniformity, the field inhomogeneity and the statistics near the cavity walls for a special case of fast changing random electromagnetic
fields. We generate this kind of electromagnetic environment by means of a vibrating intrinsic reverberation chamber. The use of several, fast, in-house, 3-axis field sensors allows for extensive, "real-time" measurements inside such a chamber.
On Excitation Periodicity in Continuously Stirred Reverberation Chambers
Reverberation Chambers (RC) provide a particularly robust environment for immunity tests by generating a statistically uniform field. The duration of such tests can be reduced for fast-responding equipment under test (EUT) by using fast, continuous stirring methods as opposed to the more common stepwise mode-tuned operation. However, continuous stirring methods, such as the Vibrating Intrinsic Reverberation Chamber (VIRC) or other flexible stirring systems, may experience periodicities in the mechanical excitation that limit the number of uncorrelated field distributions that can be generated. In contrast to the use of a conventional tuner, where the periodicity is defined by a full revolution, this is not always clear with non-rotating stirring systems. In this work the problems concerning periodicities in continuous stirring methods without rotating tuners are investigated. Using a textile flexible wall stirrer in a conventional chamber with rigid walls, possibilities are investigated to generate a maximum number of independent field distributions by breaking periodicities in the excitation.
Transnational variation in linguistic politeness in Vietnamese : Australia and Vietnam
Over the past three decades, the Vietnamese language has undergone substantial changes, both in Vietnam, and in diasporic contexts such as Australia. Yet the nature of the variation resulting from those changes at the sociopragmatic level in expressing politeness is little researched. 
The question of whether there are differences in the politeness expressed by Vietnamese speakers living in Vietnam and Australia is the focus of this research.
