China city Planning Review 2012年第2期21卷 40-51页

作者： ZHOU Jiangping, Assistant Professor, College of Design, iowa State university, iowa, the United States. Research area: urban morphology, urban transportation and sustainable urban development.

Detailed financial information of a rail rapid line project is often unavailable to the general public until a project has been completed for a couple of years and even for decades. This is especially true in the Chinese context. Based on available information, this paper compares four aspects of the financing of two rail rapid lines that were built almost simultaneously in Shanghai of China and Chicago of the US. The author finds: first, the central governments had the greatest impact on the capital investment in both lines; second, the formation of transit and financial plans in two cities both involved complicated political processes which were shaped by certain political figures and unforeseeable events; third, in the longer term, it was more expensive to maintain a rail rapid line than to build a new line in both countries; and finally, mainly depending on foreign loans and bonds, Shanghai faced greater challenge in offsetting the financial deficit. But this situation was improved as the Shanghai rail rapid system expanded and matured.

Wireless Mesh Network （WMN） has been recognized as one of the promising technologies to provide wireless broadband *** addition to the multi-radio multi-channel network architecture often seen in WMNs,employment of directional antennas on each mesh node could further improve the system throughput via alleviating the interference between nearby nodes thus allowing more concurrent transmissions in the *** this paper,we describe a novel algorithm to produce joint decisions on routing and channel assignment with practical implementation considerations for WMNs with directional *** particular,we formulate this joint optimization problem as a Mixed Integer Programming （MIP） problem with all practical considerations modeled explicitly as MIP *** example,our scheme only considers dual-path routes and oneto-one association between access points and gateway nodes,so as to facilitate its deployment with commercial wireless networking devices such as IEEE 802.11 compliant *** objective is to maximize the aggregate system throughput and to provide fair and satisfactory services to all access *** results show that our scheme （i.e.,the solution to the MIP problem） fully exploits the multi-radio multi-channel network architecture and directional antennas in WMNs,and is able to achieve the design objectives with significantly reduced implementation complexity.

To realize the internationalization of Chinese contemporary academic has long been one of the most weighty concerns and wishes of Prof. Zhang Longxi. With his personal experience in the western academic circles,Prof. Zhang believes that other humanities scholars in China also have the possibility to enter into the academic frontline of humanities and social sciences of world,and to create a dialogue with scholars from English and American academic circles on an equal footing. Furthermore,Prof. Zhang points out that this academic dialogue between the West and China is very important for both sides,so Chinese academics should try to view this dialogue in a rational attitude,and take an active part in this work. Finally,Prof. Zhang gives some perspectives and proposals for the reform of cultivation pattern to the students from the School of Foreign Languages of domestic universities or colleges.

Point Sources and Gaussian beams are used frequently as fundamental building blocks for developing ultrasonic beam models. Both these models have different weaknesses that limit their effectiveness. Here, we will show that one can develop a Gaussian Beam Equivalent Point Source （GBEPS） model that removes those weaknesses and combines the accuracy and versatility of the point source models with much of the speed and well-behaved nature of Gaussian beam models. We will demonstrate the efficiency and versatility of this new GBEPS model in simulating the beams generated from ultrasonic phased arrays, using as few as one Gaussian beam per element of the array. A single element GBEPS model will be shown to be as accurate as a point source model even when substantial beam focusing or steering is present in the array or where the array beam is transmitted through an interface. At the same time the GBEPS model will be shown to be several orders of magnitude faster than the point source model.

Coutsourides (1980) derives an ad hoc nuisance parameter removal test for testing the equality of two multiple correlation coefficients of two independent p variate normal populations, under the assumption that a sample of size n is available from each population. He also extends his ad hoc nuisance parameter removal test to the testing of the equality of two multiple correlation matrices. This paper presents likelihood ratio tests for testing the equality of k multiple correlation coefficients, and also k partial correlation coefficients.

An iterative nonoverlapping domain decomposition procedure is proposed and analyzed for linear elliptic problems. At the interface of two subdomains, one subdomain problem requires that Dirichlet data be passed to it from the previous iteration level, while the other subdomain problem requires that Neumann data be passed to it. This procedure is suitable for parallel processing. A convergence analysis is established. Standard and mixed finite element methods are employed to give discrete versions of this domain decomposition algorithm. Numerical experiments arc conducted to show the effectiveness of the method.
