For an undirected complex network made up with vertices and edges, we developed a fast computing algorithm that divides vertices into different groups by maximizing the standard "modularity" measure of the resulting partitions. The algorithm is based on a simple constrained power method which maximizes a quadratic objective function while satisfying given linear constraints. We evaluated the performance of the algorithm and compared it with a number of state-of-the-art solutions. The new algorithm reported both high optimization quality and fast running speed, and thus it provided a practical tool for community detection and network structure analysis. © 2014 Wenye Li.

While pursuing high economic growth, policy makers must be ready to bear the high economic risk accompanying that growth. The best policy is to find a realistic combination where the needed economic growth is pursued with controllable financial fluctuation. © 2014 University of Durham and John Wiley & Sons, Ltd.

Single portal association used in current WMN has bottleneck problem to make WMN potentially inefficient and bad-user-experienced. Even the existing multiple path solutions cannot tackle such problem well. In this paper, we propose MR-TBMPA (Multipath Routing using Tree-Base Multi-Portal Association) to reduce the impact brought by WMN's bottleneck problem by allowing low-work-load nodes to participate in packet forwarding through multi-portals. This work is evaluated with OMNET++ simulation and it can be found that MR-TBMPA is able to bring down the number of packet dropped by up to 70% and reduce the impact of bottleneck effect. © 2011 IEEE.

Macau's casino sector has been expanding rapidly, particularly targeting mainland Chinese gamblers. The novelty and under-researched nature of this market is a challenge for Macau's casino and destination marketers. This study explores the characteristics of the mainland market and compares this with the second placed and more mature Hong Kong market. The profiling of visitors from Macau's main source markets including demographic, region of origin, trip behaviour and motivation characteristics provides insights into the future success of the destination. Adaption theory is used to explain the implications of differences between Gambling and Non-Gambling visitors from the two source markets. © 2012 John Wiley & Sons, Ltd.

This paper presents a few design considerations in implementing building block-based Computer Aided Design (CAD) for analog switched circuits. The considered synthesis include four independent levels: 1) system level, 2) building block level, 3) circuit simulation level, and 4) layout generation, which multistage can separate a larger size circuit into a few major basic building blocks. The aim of this paper is to show how to integrate a few existing programs to shorten the design period, from the user friendly interfacing to the corresponding building blocks. A CAD tool for Switched Capacitor (SC) analogue circuit is shown briefly. © 2012 IEEE.
