To improve customer satisfaction in innovative product design, a topology structure of customer requirements is established and an innovative product approach is proposed. The topology structure provides designers with reasonable guidance to capture the customer requirements comprehensively. With the aid of analytic hierarchy process (AHP), the importance(More)
Results on finite-gain L ∞ stability from a disturbance to the output of a time-variant delay system are presented via a delay decomposition approach. By constructing an appropriate Lyapunov-Krasovskii functional and a novel integral inequality, which gives a tighter upper bound than Jensen's inequality and Bessel-Legendre inequality, some sufficient(More)
Driven by the development of high-performance piezoelectric materials, actuators become an important tool for positioning objects with high accuracy down to nanometer scale, and have been used for a wide variety of equipment, such as atomic force microscopy and scanning tunneling microscopy. However, positioning at the subatomic scale is still a great(More)
The manufacturing industries dealing with machining and tools' manufacturing generate a large amount of data concerning the machining process. However, in most cases, this information is not used in an advantageous strategy as there is no system dedicated for storing and manipulating such data. In order to Use these data to improve efficiency and increase(More)
We report here the complete genomic sequence of the porcine parvovirus (PPV) N strain, isolated in 1989 from the viscera of a stillborn fetus farrowed by a gilt in Guangxi, southern China. Phylogenetic analyses suggest that the PPV-N strain is closely related to attenuated PPV NADL-2 strains. The PPV-N strain has good immunogenicity, genetic stability, and(More)
To reduce cutting time and costs, an optimization model of cutting parameter is proposed. Constraints like lathe and cutting tool are fully considered. The objective function is aiming at the target of profit margins. Some empirical indexes are used in the constraints and the objective function since the special properties of cutting process. The Fuzzy(More)
Enterprises face increasing challenge in the designing stage which needs to turn the customer's needs into technical characteristics. In order to enhance the competitiveness of products, a demand-oriented innovative design model was proposed. This model integrates user demand accessing, technology feature mapping, quality function deployment and innovative(More)
