A novel laminated piezoelectric transducer was mainly composed of the piezoelectric ceramics, metal bolt, rubber gasket, copper electrode, waterproof layer and output cable. The transducer finite-element modeling was built, separately in the air and water, with ANSYS10.0 to calculate the resonance frequency, conductance, transmitting voltage response and directivity. The simulation showed that the laminated structure effectively improved the sensitivity of the piezoelectric transducer. The maximum transmitting voltage respond of the laminated piezoelectric transducer can achieve more than 155 dB, compared with a traditional design by approximately 10%.

Appropriate locations for distribution centers benefit both distribution centers and their clients. Many location models of distribution centers base on the assumption that the companies that the distribution center serves are known. Few literatures touch on the issue that if the right companies have been found as the service objects for the distribution center. This paper believes the better way is to find the right service clients first, and then, build location model based on it. And this paper focuses on the identification of the service clients and other decisions can be made based on the identification result. In order to find the right clients for distribution centers a network which can reflects the transport relationships among companies is created first. Then the companies that should share logistics service are identified through community detection method. The companies belonging to a same community of the network may become the right service clients for a distribution center.

In this presented note, triangular norms are studied in the general setting of bounded partially ordered sets(posets). The sets of idempotent elements, zero divisors and nilpotent elements associated to a t-norm are introduced and related to each other. The Archimedean of t-norms is discussed, in particular its relationship to the diagonal inequality.

This paper describes a methodology to determine a set of optimum nonlinear system parameters for a passive suspension system (PSS) by using the evolutionary algorithms so that the best performance of the system can be achieved. The selected fitness functions are based on the desired performance such as sprung mass acceleration, suspension deflection, and tire deflection. A dynamic step-size operator is incorporated in the evolutionary algorithm for fine-tuning the mutation process. The simulation results show that the proposed method can provide better ride comfort and road holding ability in comparison with the commonly used passive suspension system.

In this study, a robust algorithm with a fuzzy sliding model controller (FSMC) is used to synchronization of a Duffing-Holmes system. The robust algorithm is an output factor of the fuzzy sliding model controller. The control rules of FSMC are based on the Lyapunov stability theorem. The objective of synchronization is to study a master-and-slave system to be synchronized with both uncertainties and disturbances added in the slave system. Simulation results show the effectiveness of the proposed method.

In MANETs, the scalability problem has been solved by the clustering mechanism. However, current clustering algorithms consider on the network stability only in terms of some metrics affecting innercluster structure's stability, and neglect some metrics affecting intercluster structure's stability which are more favorable to global stability. To solve this problem, a clustering algorithm is proposed in this paper. It gives a comprehensive measurement on stability metrics of the innercluster structure and the intercluster structure. For a better comprehension of our algorithm, an explanatory example is given. To compare the performance of our algorithm to that of clustering algorithms with clusterheads, we simulate the structural adjusting times and network overheads during the process of the cluster formation and maintenance. The conclusion shows that our algorithm is more favorable to the stability of the global hierarchical structure and reduces network overheads a lot, which improves the global network performance.

LPP (locality preserving projection), as a linear version of manifold learning algorithm, has attracted considerable interests in recent years. For real time applications, the response time is required to be as short as possible. In this paper, a new local image descriptor-LPP-HOG (histograms of oriented gradients) for fast human detection is presented. We employ HOG features extracted from all locations of a grid on the image as candidates of the feature vectors. LPP is applied to these HOG feature vectors to obtain the low dimensional LPP-HOG vectors. The selected LPP-HOG feature vectors are used as an input of linear SVM to classify the given input into pedestrian/non-pedestrian. We also present results showing that using these descriptors in human detection application results in increased accuracy and faster matching.
LPP (locality preserving projection)作为流形学习算法的一种线性版本，近年来引起了人们的广泛关注。对于实时应用程序，响应时间需要尽可能短。本文提出了一种新的局部图像描述符——定向梯度直方图(histograms of oriented gradients, lpp - hog)。我们使用从图像上网格的所有位置提取的HOG特征作为特征向量的候选。对这些HOG特征向量进行LPP处理，得到低维LPP-HOG向量。选取的LPP-HOG特征向量作为线性支持向量机的输入，将给定的输入分类为行人/非行人。我们还展示了在人体检测应用中使用这些描述符可以提高准确性和更快的匹配速度。
