We demonstrate an extension to the SHARPER (Sensitive Homogenous and Refocussed Peaks in Real Time) NMR experiment which allows more than one signal to be monitored simultaneously, while still giving ultra-sharp, homo- and hetero-decoupled NMR signal

Pure-shift NMR enhances spectral resolution, but the optimal resolution can only be obtained at the cost of acquisition time. We propose to accelerate pure-shift acquisition using optimised ‘burst’ non-uniform sampling schemes [I. E. Ndukwe, A. S

Packet forwarding with source verification

Publikováno v: Computer Networks. 52:1567-1582

Routers in the Internet do not perform any verification of the source IP address contained in the packets, leading to the possibility of IP spoofing. The lack of such verification opens the door for a variety of vulnerabilities, including denial-of-s

PMD and PDL Behavior of Aerial Fiber with the Accelerated Jones-Matrix Eigenanalysis

Publikováno v: Optical Fiber Communication Conference.

Polarization characteristics of aerial SMF were examined with the accelerated Jones-Matrix Eigenanalysis, comparing to interferometric method. PMD shows strong correlation with environmental changes but PDL doesn't. Both instantaneously increase howe

Positive and negative correlation between ambient temperature and DGD on buried field fiber

Autor: Takao Naito, A. Lee, Youichi Akasaka, Matthew Davy, Inwoong Kim

Publikováno v: OECC/ACOFT 2008 - Joint Conference of the Opto-Electronics and Communications Conference and the Australian Conference on Optical Fibre Technology.

Positive and negative correlations between ambient temperature and DGD values were observed on 160 km buried field fiber with long term measurements. The strong correlations tend to be on wavelengths of local maximum and minimum DGDs.
