The research mainly focuses on water resources allocation plans of northern China. By applying multi-attributes decision-making method, it can help...

In CNC machinery, the industrial products and machinery parts are often represented by circular arcs. A new method for representing circular arc based on parametric complex functions is presented in the paper. Since cross ratio is an invariant of the group of all Möbius transformations, and a Möbius...

The image low level features have a gap with the high level semantic feature which human understand, the researches begin to focus on automatic semantic annotation image retrieval rather than on content image retrieval. The previous methods mostly base on single kernel learning, which has some limitations,...

Genetic algorithm(GA) is a powerful tool for the analysis of the mechanism and dynamic responses of the fermentation process,and for process optimization and automatic control.In this research,the structured and unstructured mathematical models and computer simulation of MT production and RFP fluorescence...

The government wants to achieve the goal put forward in the eighteenth Congress of the Chinese Communist Party. It needs to improve efficiency. Therefore, the efficiency of agricultural information is particularly important for a large agricultural country like China in the information age. Through constructing...

With drug finished-parts storage area increases, the control system of fan increases, interactions among multiple fans is inevitable. It is difficult to meet the requirements of the new GMP for finished-parts storage temperature and humidity. Multiple draught fans coordinated fuzzy PID control strategy...

Construction of university Data Center is the requirement of higher education to adapt to information society, is also an important part of the construction of universities. At present, due to the informationization construction of universities lacking of unified planning and deployment, as well as the...

This study investigates the numerical simulation and theoretical modeling of longitudinal compressive failure in fiber reinforced composite materials. Firstly the numerical simulation of longitudinal compressive failure is conducted. The simulated results show that at one moment of the loading, the localized...

Geometry based knot tying simulation of rope was implemented. The rope was modeled as a series of rigid links and FTL (Follow the Leader) algorithm was used for its deformation. Cylinders were drawn as the rigid links and also as detecting units for the rope’s collision detection. The radius of cylinders...

Whether there is a feasible flow of ventilation network that meets the demand of fixed airflow and the balance of airflow, when the number, quantities of fixed branches are all uncertain. It is called fixed airflow distribution problem, which was transformed into flow distribution problem. All branches...

Against the incomplete information in the basin hydropower cascade system and bounded rationality of the behaviors of market subjects and through the analysis of competition and cooperation between the different interest groups of the river basin cascade hydropower stations, the dynamics model of evolutionary...

The traditional bag-of-visual-words(BOV) model only uses one single feature to classify objects, which is difficult to achieve good results when dealing with many object categories. To solve this problem, in this paper, we proposed an object recognition method based on BOV model and fusing multi-feature....

Small and medium-sized enterprises (SMEs) are the engines of global economic growth. In the today competitive environment consumers demand a more personalized treatment and products andor services that better meet their needs. SMEs can successfully remain in the global market if they can respond to the...

With the number of 3D shapes has risen sharply, a fast and robust matching technology suitable for large 3D shape databases is one of the key technologies to enhance the retrieval performance. We proposed a general novel matching algorithm for 3D shape retrieval: SRRSM, based on sparse representation...

Conventional multi-view theory fails to explain underwater stereo vision because of the refraction bends light rays. This paper focuses on one of the most common scenarios of underwater vision, a stereo vision system of two cameras with a flat housing, in which the light ray refracts twice, once at the...
