Design of a hybrid free space optical and visible light communication system for indoor wireless data broadcasting

Autor: M Y Cheong, W L Pang, G C Chung, I E Lee, S S Anas

Publikováno v: Journal of Physics: Conference Series. 1432:012065

The continuous development of online social services and the ever-increasing number of devices demanding high-speed and ubiquitous broadband wireless access have resulted in severe bandwidth congestion, such that the radio frequency (RF) spectrum wil

Multi-user access interference suppression for UWB system

Autor: G. C. Chung

Publikováno v: 2012 International Conference on Computer & Information Science (ICCIS).

In Ultra Wideband (UWB) multi-user environments, the existence of severe multi-user access interference (MAI) can cause significant performance degradations. In this paper, we propose an adaptive least bit error rate (LBER)-Rake receiver for synchron

Compositional Dependence of Segmental Dynamics in a Miscible Polymer Blend

Autor: G.-C. Chung, Steven D. Smith, Julia A. Kornfield

Publikováno v: Macromolecules. 27:5729-5741

The segmental motion of each species in polyisoprene/poly(vinylethylene) (PI/PVE) miscible blends is studied at three different compositions using two-dimensional deuteron exchange NMR (2D ^2H NMR). The individual species exhibit widely different mea

Component Dynamics Miscible Polymer Blends: A Two-Dimensional Deuteron NMR Investigation

Autor: Julia A. Kornfield, G.-C. Chung, Steven D. Smith

Publikováno v: Macromolecules. 27:964-973

The dynamics of individual components in 1,4-polyisoprene/poly(vinylethylene) miscible blends are studied using two-dimensional deuteron exchange NMR. The rate of the backbone reorientation process near the glass transition is quantitatively determin
