In order to reconstruct the all-in-focus image from a conventional camera, a spatially-varying defocus deblurring approach based on blur map and TV/L2 regularization was proposed. Firstly, lenticular defocus model was studied and analyzed, and the principle, characteristic and applicability of disk defocus model and Gaussian defocus model were generalized; Secondly, we modified the local contrast...
Energy overconsumption and greenhouse gas emission have been contributing to air pollutions and the global warming for years. The unceasingly increasing number of fossil fuels based vehicles around the world is considered as one of main factors making to the situation worse year by year. Electric vehicles (EV) are promoted as a viable and promising alternative transportation means for customers. However,...
Ontology as a concept and model description way, is widely used in various fields, and achieved good effect. Ontology based on intelligent Agent how to realize its definition of the concept in Meta search engine, help system realize the personalized, still need further research. This paper put forward a meta search engine personalized mechanism based on ontology with the use of the Agent technology,...
In order to promoting products development period and improving production quality, all enterprises have found the digital factory is a good comprehensive solution approach. However, for complex products, there is still lack of open integration possibilities among products and production manufacturing process modeling, simulation, analyzing, visualizing and optimizing systems tools on a multi criteria...
Flash-based Solid-State Drives (SSDs) have become a promising alternative to magnetic Hard Disk Drives (HDDs) thanks to the large improvements in performance, power consumption, and shock resistance. An accurate SSD performance model will provide the important research tools for exploring the design space of flash-based storage systems. While many HDD performance models have been developed, architectural...
Digital factory is a new technology to construct a virtual plant environment to implement integration between process planning and manufacturing execution. Object-oriented technology is introduced to simulate complicated discrete-events system with constructing four basic objects including product, process, planning and resource in digital factory environment. Especially manufacturing resource library...
Collaborative design and simulation is the key technique for complex product development, which is a highly complicated multidisciplinary process. The information sharing and model transferring among different disciplinary domains are the bottleneck of complex product collaborative design and simulation. To solve this problem, this paper proposes the complex product collaborative design and simulation...
