In order to automatically extract the main melody contours from polyphonic music especially vocal melody songs, we present an effective approach based on a Bayesian framework. According to various information from the music signals, we use a pitch evolution model describing how pitch contour changes and an acoustic model representing the acoustic characteristics when the pitch is a hypothesized one,...
With the increase of science project in size and complexity, it is necessary to integrate and share global research resources for distributed experimentation and simulation. This paper presents an architecture of Cooperative Remote Laboratories (CRLab) with scalability, flexibility and heterogeneity. It consists of a central Web server, simulation servers, instrument servers and experiment devices,...
This paper has applied systematic ideology, inductive and deductive methods to analyze the regional science and technology policy of the EU and its inspiration for China. The regional science and technology policy of the EU is closely related to the regional policy of the EU and it has played very important role in solving the regional problems of the economic recession regions in the EU. The successful...
High speed machining technology is used in a broad range of applications to machine ferrous metals and nonmetallic material. Based on its application, a motorized high speed, high power/torque spindle is the key technology that drives high speed machining. Performance monitoring determines if the equipment is operating as expected. This paper presents a new motorized spindle performance monitoring...
This paper studies the forming process of customer value based on grounded theory. Through mining the factors and analyzing the relationship between them during the customer value formation, the model of customer value is constructed in a business to customer market. At the same time, the paper build the measuring model and propose four types of customer measurement: the measurement of each factor...
Along with the computer technology developed soon, the software scale enlarged continuously, and the complexity raises continuously, the software crisis is also emerged obviously more and more, so it's necessary that make the mode of software produce conversion from the handicraft workshop production of personal and group to the large-scale socialization production of profession division of labor,...
