On the basis of general pivot method for paraphrase extraction which might introduce much noise in extracted paraphrases, this paper proposes a syntactic knowledge-enhanced method to extract higher-quality paraphrases to further improve the quality of statistical machine translation. Firstly, the syntactic knowledge is acquired and added to paraphrase extraction algorithm as constraints to obtain...
Feature model is an important model of capturing domain requirements. The traditional feature modeling methods extract the characteristics from the extension of the system. However, the methods fail to describe feature in details especially for embedded software product line engineering. As for these deficiencies, this paper combines the characteristics of the embedded products, with the domain ontology...
A virtual prototype model of wall finishing robot is developed and the force situation in the working process has been analyzed. Applying SolidWorks and its CAE packages, operating characteristics under the real project condition are shown by simulation analysis so as to provide a reliable basis for the design and manufacture of the prototype.
By analyzing stress bear and distribution of wall finishing robot guide rails, this thesis puts forward a measuring method based on PSD measurement circuit to measure robot lift rail tilt angle. Meanwhile, wall finishing robot tilt automatic correction servo system is completely designed and simulation analysis is carried out on the servo system and the servo correction results.
This paper proposes a novel algorithm for parking motion of a Car-like mobile robot. The algorithm presented here addresses calculating equations for planning a parking path in real time. Moreover, by incorporating the constraints of the mechanical and kinematical characteristics of the car and the geometry of the parking lot in the path planning, we can turn a parking problem into solving algebraic...
