Presents the front cover or splash screen of the 2013 Fifth International Conference on Measuring Technology and Mechatronics Automation proceedings record.
Though many varieties of recommendation systems have been developed to greatly promote the intelligent level of E-commerce websites for recent years, IEEE Internet Computing points out that current system can not meet the real large-scale e-commerce demands", "and has some weakness such as low precision and slow reaction. The personalized recommendation system model based on case intelligence...
In prediction of dam safety monitoring, single models such as mathematical model and neural network model are established according to different modeling mechanism. The effective combination of these single models can make full use of all useful information and improve the fitting and forecasting precision. The most commonly used combination method is weighted arithmetic averaging combination forecasting...
The paper presents a detailed methodology for dynamic modeling of ROV with a robotic manipulator using Kane's dynamic equations. This methodology allows construction of the dynamic model simply and incrementally. The generalized active forces and the generalized inertia forces were deduced. The forces which contribute to dynamics were determined by Kane's approach. The model developed in this paper...
The conventional K-harmonic means is tend to be trapped by local optima. To resolve this problem, a novel K-harmonic means clustering algorithm using enhanced differential evolution technique is proposed. This algorithm improves the global search ability by applying Laplace mutation operator and logarithmically crossover probability operator. Numerical experiments show that this algorithm overcomes...
The median filtering algorithm has good noise-reducing effects, but its time complexity is not desirable. The paper proposed a new median filtering algorithm. The algorithm uses the correlation of the image to process the features of the filtering mask over the image. It can adaptively resize the mask according to noise levels of the mask. The statistical histogram method is also introduced in the...
The braking situation is important information in vehicle-pedestrian accident responsibility identification. In order to distinguish the braking situation, the relation between the post-braking distance and the throw distance on slope roads were studier firstly, and then the Pc-Crash and those existing research results were used for validating the proposed relation, finally a method used for analyzing...
In this paper, a method is established, using finite difference method, to predict the longevity function. This method can effectively deal with non-linear, shock, non-convergence data. The method can get a longevity function by poly-fitting the data, in the situation that common fitting method cannot work well. The result of one experiment is used as an example, in which the data are analyzed and...
The quality of the image is one of the important influential factors in the process of defect evaluation of weld radiographic image. To improve the brightness and contrast of digital image of weld radiographic film, a new quality enhancement method in accordance with human visual system is proposed. The human visual resolution ability of the gray and the imaging model of digital system are introduced,...
This paper is intended to apply the spatial impulse response method to simulate the acoustic field of a line phased array transducer. The focus laws of ultrasonic linear phased array and the expressions of the acoustic field are obtained utilizing the impulse response of rectangular transducer. Simulations are carried out for a linear phased array transducer in different focusing angles. It is shown...
Logistics customers and service agents share the service order and resource information in cloud-network system which can cause the collaborative operation, reduce costs and improve efficiency. This paper studies on the price determining model in intelligent system, which is important to the operation maintenance of logistics cloud-network system after the technical achievement. The paper studies...
This paper proposes a two-step system that uses practically obtainable channel state information. We will show how a two-step MMSE MIMO estimator can be used to facilitate packet detection as well as to provide superior bit error rate performance. A pre-filter is used to improve synchronization performance. a secondary filter will estimate the originally transmitted signal.We will show how this approach...
