Model-based object clustering is a very challenging unsupervised learning problem in computer vision, which involves both high dimensionality and hidden variables inference issues. In this paper, we will study object pattern clustering problem by using the Active basis model, which is a sparse representation model for object patterns. We fit a mixture of active basis models, which leads to an object...
In this paper, aiming at the water-consuming of the circulating water system in the petrochemical enterprises, the stage-wise super structure model of the heat exchanger network is established. And the model can be solved by using the MINLP programming method. Considering the characteristics of no-shunt and shunt, the simultaneous optimization of heat exchanger networks is implemented, which is based...
Boron lined gaseous detector is one of the alternative detector types that possibly replace the helium-3 counter. The most important problem in the realization of boron-lined gaseous detector is how to plate thin boron film on the surface of large area substrate. Though methods of PVD (physical vapor deposition) can plate B4C layer effectively with good thickness uniformity and adhesion, they suffer...
A design of a broadband circularly-polarized (CP) slot antenna is proposed in this paper. The CP radiation of the slot antenna is excited by the proximity coupling of a microstrip line. To obtain a broad CP bandwidth, three CP modes contained in the CP band are excited. The results show that the proposed antenna can provide a CP operating bandwidth of 56% (3.17 GHz–5.65 GHz) within an impedance bandwidth...
Innovation resource utilization is closely related with the capability of transforming regional innovation resource into innovation income. While the issue of industry cluster innovation network and its performance becomes a hot topic in recent research, we posit that innovation network structure could influence the capability of network's innovation resource utilization and thus enhance performance...
Extenics is a theory to solve the contradiction problem, it will be a new way to look for and find knowledge through analysis the contradiction and transformation the result of the data mining using the extension methods. In this paper, introduced the matter-element and extension set that is the base of the extenics, researched the way to find out and generate the new knowledge that help by the divergence,...
The optimization of coagulant dosage in drinking water treatment has become an issue of particular concern for utility managers. We studied the shortage of the operational control methods. And this paper presents the application of ANN to model the prediction of coagulant dosage. The model is constructed based on the database of operating parameters and water quality. The structure and the parameters...
In this paper, a kind of adaptive control based on fuzzy hierarchical approach for the permanent magnet linear synchronous motor (PMLSM) is proposed. According to different hierarchy of error state, one of the traditional fuzzy controller and integrator is applied. The servo control system can switch from traditional fuzzy controller to integrator smoothly when the control system is close to stable...
