Attention to Effects of Different Cross-Cultural Levels in User Research Method’s Interface: Discipline or Nationality – Which Has Stronger Force?
No full textIn the recent years, design research have developed a long way in investigating about the users and their contexts. It was aimed to challenge the way ‘cross-culture influence’ has been considered in design research field: should there be better way than profiling users solely based on nationality in multinational research project for product specification. Major findings through this research included (1) Nationality factor influenced remarkably on user performance but not much on user attitude. In contrast, discipline factor influenced significantly on every elements of user participation. (2) The gaps of user attitude and performance with nationality as the function maintained same levels while the effects from discipline factor intensified upon the increase of task complexity and change of ask characteristic. Overall, Discipline factor dominated Nationality factor, insisting on the importance of considering different levels of participants’ cultures in designing the interface of user experience research methods

Contributions to the asymptotic study of Hermite driven processes
No full textThis thesis consists of two parts.
Part I is an introduction to Hermite processes, Hermite random fields, Fisher information and to the papers constituting the thesis. More precisely, in Section 1 we introduce Hermite processes in a nutshell, as well as some of its basic properties. It is the necessary background for the articles [a] and [c]. In Section 2 we consider briefly the multiparameter Hermite random fields and we study some less elementary facts which are used in the article [b]. In section 3, we recall some terminology about Fisher information related to the article [d]. Finally, our articles [a] to [d] are summarised in Section 4.
Part II consists of the articles themselves: [a] T.T. Diu Tran (2017): Non-central limit theorem for quadratic functionals of Hermite-driven long memory moving average processes. Stochastic and Dynamics, 18, no. 4. [b] T.T. Diu Tran (2016): Asymptotic behavior for quadratic variations of nonGaussian multiparameter Hermite random fields. Under revision for Probability and Mathematical Statistics. [c] I. Nourdin, T.T. Diu Tran (2017): Statistical inference for Vasicek-type model driven by Hermite processes. Submitted to Stochastic Process and their Applications. [d] T.T. Diu Tran (2017+): Fisher information and multivariate Fouth Moment Theorem. Main results have already been obtained. It should be submitted soon

APPENDIX: AUTHOR'S PUBLICATIONS LIST 79DoctoralOne of the most important component of integrated photonics is a class of devices known as light modulation devices, which allow us to modulate and manipulate the flow of light, similar to the role transistor played in electronics. Only recently introduced, but graphene have shown incredible promises as a "miracle" material in electronics, with properties ranging from zero band gap, very high electrical mobility, ultra broadband optical responses, and the ability to drastically modify its optical properties through chemical or electrical doping.
In this dissertation, the author presented several unique nanostructures to exploit the aforementioned graphene characteristics to create light modulation devices with superior performance characteristics. Novel effects including wide angle extraordinary reflection causes by epsilon near zero effect and wide angle extraordinary transmission causes by coupling of plasmonic supermodes, phase modulation with near unity amplitude transmission with all pass filter, and graphene perfect absorber with a coupled system of dual mode/single mode resonator was thoroughly investigated, theoretically and numerically. The effects was also presented in practical nanostructures better suited for applications, which are also numerically investigated with various numerical methods
