The problem of coordinating activities while developing large software systems is challenging. In this paper, we formulate a quantitative coordination model to analyze the optimal management policy for incremental software development. Then we develop an effective solution procedure with polynomial complexity to solve the model. Numerical studies show: (1) too large a team size is counter-productive...
This paper proposes a new construction method of binary sequence pair sets with zero correlation zone (ZCZ) in which the correlation functions of sequence pairs are zero, based on difference set pair, a new concept of combinatorial mathematics. With the extension of sequence length, the sets achieve the theoretical upper bound. These ZCZ sequence pairs can be applied to the generalized quasi-synchronous...
The co-occurrence of the name entities in sentences and documents usually implies some important relationships among them. This paper addresses relation extraction problem and proposes an unsupervised method of automatic discovering relations among entities based on community structure mining. After distilling all named entities pairs, a network is constructed to represent the semantic relationship...
Based on the integration of RS, GIS and GPS technologies in the study area during the 10 years from 1992 to 2002, we reached the following main conclusions. First, the areas of forestlands, grasslands and waters were reduced, whereas the areas of other land use types were enlarged. Second, the land of construction increased greatly, especially in the suburb of Baotou City and the environment of the...
