We study the controllability of the linear and nonlinear systems with constant control, where the matrices are continuous, the nonlinear function is a vector function and continuous.
Customer knowledge management emphasizes collecting, storage, analysis and use of customer knowledge. This is closely related to customer relationship management. This paper, by analyzing the connection between the customer relationship management and customer knowledge management, constructs the model of customer knowledge management based on CRM, to help enterprises to track the whole process of...
The central pattern generator(CPG) is used to control robot very well. But the adjustment of CPG parameters and it's interaction with the external inputs are still open problems. Based on biological knowledge, the central nervous system rules the switch of the CPG modes. In this paper we focus on the coupling relationship between the cerebral cortex and the CPG and establish the mathematical model...
Virtual experiment by creating virtual experiment laboratory instruments and laboratory scene to simulate the real experiment, is a process through a computer interface operation of virtual instruments and systems, and to complete the experiment. This paper first analyzes the specific content of human-computer interaction in virtual experiments design. Then put forward five principles on human-computer...
A brain-computer interface (BCI) is a system for direct communication between brain and computer. The P300 BCI system relies on an oddball paradigm to elicit the P300. With the aim to extract different P300 feature information from different subjects and reduce the data amount of electroencephalogram (EEG) in P300 classification, a P300 feature extraction algorithm is proposed, which is based on independent...
This paper proposes a modified version of opinion communication based on naming game to simulate the formation of opinion in real society. In the version, freshness is brought in to measure memory level of one opinion for each agent, when various opinions exist in social population. Main researches are devoted to new opinion replacing old opinion after system already convergences to an opinion, revealing...
With the continuous development of network, the damage of the public opinions spreading is expanding. It is researched that under the effect of the herd instinct, how does the process of the individuals in the network cognize the public opinions evolve, uses the coordination game with the factor of non-rational to building the model of interaction among the neighbors. It has been studied that individuals'...
Adaptive boosting (AdaBoost) can boost a weak learning algorithm with an accuracy slightly better than random guessing into an arbitrarily accurate strong learning algorithm. It has been applied to target recognition with single feature classifier. However, the poor discriminative power of extremely weak single feature classifier limits its application. In this paper, we present a novel comprehensive...
A new search algorithm for phased array radar which is based on radio frequency stealth is proposed in this paper. When there is no indication information, parameters including the dwelling time and the average power are optimized by sequential quadratic programming (SQP), and a minimum energy cost model is set up by using Grey Relational Grade (GRG). The surveillance area is divided into several...
Travelling salesman problem (TSP) is one of the famous discrete optimization problems. Due to its NP-completeness, the exact methods are not found till now. Here we use a nearest neighbor method to search the approximations with a frequency graph. The frequency graph is computed with a set of local optimal paths derived from a weighted graph. The frequencies on the edges represent the number of edges...
Combustion process in utility boiler is very complicated and not fully understood until now. One operating challenge in boiler operation is the unreliable oxygen sensor could result in flame extinction of burners. An on-line virtual sensor is desirable for the unreliable oxygen sensor. This work elaborates how to build a Neural Network-based oxygen virtual sensor by make full use of the mass data...
In the SINS swing base initial alignment process, the filtering model is nonlinear error model because of the large azimuth misalignment angle. The alignment adaptivity can be improved efficiently with the combination of strong tracking theory and UKF. In this paper, the fuzzy logic adaptive controller is applied to confirm the tracking factor, which can enhance the adaptivity of the strong tracking...
This paper discusses the structure of the Java EE platform firstly, and then analyzes and introduces the framework of Strust2, Spring and Hibernate. This three kinds of framework plays a different role in different layer of the Web application. The solution of the remote health service system is put forward through the integration of the three framework. This system provides a convenient interactive...
In order to optimize the human-computer interaction technology of 3D interface, and solve the problem of realizing the three-dimensional moving operations via two-dimensional plane by controlling the mouse, after achieving the target of model can move freely in 3D space, it has researched the algorithm of models move intelligently in 3D space, by introducing the thought of bounding box and using improved...
Lung disease is often performed as nodules. Pulmonary nodule is one of important symbols of lung disease. Characteristics of pulmonary nodules always indicate the nature of lung disease. Detection of pulmonary nodules has great significance in diagnosing lung cancer. Study of pulmonary nodules is now a hot research. CT is a new type of medical imaging equipment with a high density resolution and adequate...
The purpose of the spare parts inventory is used to maintain the normal operation of the equipment, the best metric to measure the merits of the spare parts inventory levels is the use of security equipment. Therefore, Under the constraint of the total supply of spare parts cost, based on spare parts of marginal utility analysis, here propose maintenance waiting time as the objective function of optimization...
This paper presents the design and evaluation of an intelligent tourist guide system that runs on Android tablets with GPS feature. The main steps of system design and implement are described in detail. The results of a follow-up user study show that the intelligent tourist guide system is very helpful for tourists, particularly enhancing self-guided tours and improving tourists' experience in their...
The complex network theory is applied to manufacturing, manufacturing of complex networks have been proposed fault model construction methods. According to the four different manufacturing network, based on the performance of a large number of experimental data of successive failure model is analyzed.
Breast cancer is the most common malignant tumor for women. In the past twenty years, the incidence of breast cancer continues to rise. Then, the diagnosis and treatment of the breast cancer have become an extremely urgent work to do. In this study, we intend to build a diagnostic model of breast cancer by using data mining techniques. A feature selection method, INTERACT is applied to select relevant...
