Recognition of the initial position of weld based on the image pattern match technology for welding robot
The application of recognition for the weld seam and its initial position in a complicated environment based on the image pattern match technology has been discussed.
According to adopting the two-step pattern match method, the recognition speed and accuracy have been improved, and the error points have been wiped off during the global pattern match stage by using the area analysis method.
The initial position can be accurately recognized by using the method that dynamically adjusts the search area during the local pattern match stage in the area that is near the end of the weld.
It first performs a database pattern match and then ranks candidates on the basis of their similarity to the query peptide.
The required degree of laser and interferometer mode matching is estimated and the effect of the output mode cleaner is revealed.
Fiber optics resolves the mode matching problems in conventional optics and provides mechanically stable optical circuits.
The dispersion characteristics of a class of closed dielectric waveguides are investigated by the method which combines the building-block approach of multimode network theory with the rigorous mode matching procedure.
Analysis of monopole antenna on circular disc by mode matching
Mode matching is used for the analysis of monopole antenna on circular disc, which is achieved by developing a novel model consisting of two artificial ground planes above and bellow the monopole antenna.
The proposed model was used to solve the problem of schema matching between data source schema and database schema.
A survey of approaches to automatic schema matching
Schema matching is a basic problem in many database application domains, such as data integration, E-business, data warehousing, and semantic query processing.
In current implementations, schema matching is typically performed manually, which has significant limitations.
We intend our taxonomy and review of past work to be useful when comparing different approaches to schema matching, when developing a new match algorithm, and when implementing a schema matching component.
