Many stores are introducing tools for customer self-service, such as product searches and store navigation. Using mobile devices, such as the customers' smartphones and tablets, services of this kind can be enhanced to allow a customer to obtain product and store information more quickly. In such an environment, a history of customer queries can be stored daily in a database system maintained by the...
A construction method of the interval wavelet is proposed based on constrained variational principle, and a quasi-Shannon interval wavelet is constructed by this method. The linear, the conic, the quartic and the sine function are approximated using quasi interval wavelet, the affection of width parameter r and the number of external collocation points L on the computation precision is discussed,...
The idle speed control is one of the most important automotive control problems. In this paper, the engine idle speed control problem comes down to optimization problem with input and state constraints. The controller using model predictive control (MPC) methodology based on linear programming is designed to regulate the engine speed. The simulation results show that the approach is an effective and...
With increasing of the use of helicopters for transmission line inspection, the image processing technology is used to inspect the status of the transmission lines. In this paper, an algorithm of transmission line automatic extraction and recognition from natural complex background in aerial images is presented. A developed Marr-Hildreth edge detecting algorithm was used to enhance the linear features...
Concept hierarchies are important in many generalized data mining applications, such as multiple-level fuzzy association rule mining. Usually concept hierarchies are given by domain experts. However, it is extremely difficult and time-consuming for human experts to discover concepts and construct concept hierarchies from the domain. In literature, several representations of concept hierarchy are possible,...
A new model of Behavior Selection (BS) of Artificial Life (AL) based on the priority degree is presented. This paper studies the lax hierarchical model provided by the literature [ 1], fully considers the effects of action preference (AP) to BS, further adds the dodge action (DA) to the original hierarchical model. Emulation results prove that this developed model can make the AL’s behavior more reasonable...
We consider in this paper a class of stochastic team and nonzero-sum game problems with more than two agents who have access to decentralized information and may build their own subjective probability models to be used in the decision process. There is, in general, no compatibility between different models built by different agents, and this makes the available theory on teams and games inapplicable...
