Kaohsiung, Taiwan

National Sun Yat-sen University is a leading public research university located in Gushan District, Kaohsiung, Taiwan. It is considered as one of the most prestigious universities in Cross-Strait Economic Zone, 4th best ranked higher education institution in Taiwan, and one of 40 best universities under the age of 50 worldwide.Named after Dr. Sun Yat-sen, NSYSU was founded in 1980 as a re-established version of the original Sun Yat-sen University. This re-establishment has been made possible through the efforts of alumni of both the original Sun Yat-sen University and the historical Moscow Sun Yat-sen University.NSYSU comprises six colleges and is well known for its oceanography, cutting-edge technologies, business management, political science programs and strong ties with government officials. It presently receives funding from the "Aim for the Top University Project" of Taiwan’s Ministry of Education and is one of the four universities that make up Taiwan's Public Ivy, the Taiwan Comprehensive University System.The NSYSU campus is a natural fortress, it's surrounded on four sides by sea and mountain.

This technical note concerns robust stability analysis of discrete-time linear-time-invariant (LTI) systems with varying time delays. The stability problem is tackled under the integral quadratic constraint (IQC) framework. The time-delay system in question is viewed as feedback interconnection of an LTI stable operator and the so-called delay-difference operator, for which IQC characterizations are required in order to apply IQC analysis. One of the main contributions of the technical note is to derive novel IQC characterizations for the delay-difference operator, based on the assumption that the time-varying delay parameter and its variation are bounded. A set of new stability criteria emerges as the result. Numerical examples are given to illustrate the effectiveness of the new stability criteria. Another distinct contribution is the idea of introducing bounds on the so-called $m$-step total variation and $m$-step average variation of the time-varying delay parameter, which is proven to be useful in stability analysis. © 2012 IEEE.


This work theoretically studies the transmission performance of a DML-based OFDM system by small-signal approximation, and the model considers both the transient and adiabatic chirps. The dispersion-induced distortion is modeled as subcarrier-to-subcarrier intermixing interference (SSII), and the theoretical SSII agrees with the distortion obtained from large-signal simulation statistically and deterministically. The analysis shows that the presence of the adiabatic chirp will ease power fading or even provide gain, but will increase the SSII to deteriorate OFDM signals after dispersive transmission. Furthermore, this work also proposes a novel iterative equalization to eliminate the SSII. From the simulation, the distortion could be effectively mitigated by the proposed equalization such that the maximum transmission distance of the DML-based OFDM signal is significantly improved. For instance, the transmission distance of a 30-Gbps DML-based OFDM signal can be extended from 10 km to more than 100 km. Besides, since the dispersion-induced distortion could be effectively mitigated by the equalization, negative power penalties are observed at some distances due to chirp-induced power gain. © 2012 Optical Society of America.

A tung(sten) twister: Heating 1 in chlorobenzene affords 2, 3, C 6Ph 6, and C 60, and involves C-H bond activation and C-C bond formation of the ligands, as well as chlorine atom abstraction from the solvent. C 6Ph 6 is presumably generated from insertion of the benzylidyne ligand into the C 5Ph 5 ring. Compound 3 is an air-stable, 17-electron species, with the phenyldichloromethyl ligand having a unique η 3-allyl-type bonding motif. Copyright © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
