Experimental Section Materials. N-Isopropylacrylamide (NIPAM, 97%, Tokyo Kasei Kagyo Co.) was purified by recrystallization from a mixture of benzene and n-hexane (1/3, v/v). Styrene (St, 99.5%, Beijing Chemical Factory) was successively washed with aqueous NaOH (5.0 wt %) and water, then distilled over CaH 2 at reduced pressure.(More)
— Aiming at the problems of the traditional feature selection methods that threshold filtering loses a lot of effective architectural information and the shortcoming of Bagging algorithm that weaker classifiers of Bagging have the same weights to improve the performance of Chinese architectural document categorization, a new algorithm based on Rough set and(More)
Aiming at the problem of the traditional feature selection that threshold filtering loses a lot of effective architectural information and to improve the precise of Chinese architectural document classification, a new algorithm based on rough set and C4.5Bagging is proposed for Chinese architectural document categorization. Firstly the cores of attribute(More)
—In this paper, we present a pseudo-stochastic variation of the Metropolis dynamics for combinatorial optimization in concrete CT image classification using Markov Random Fields. The method is a modified version of the Metropolis (MMD) algorithm: at each iteration, the new state is chosen randomly, but the decision to accept it is purely deterministic. This(More)
In recent years, the architecture quality problem has been getting more and more attention. Concrete is a sort of savageness disfigurement material and is abroad in architecture industry. But concrete meso-structure has not been more analyzed. In this paper, we present a pseudo-stochastic variation of the Metropolis dynamics for combinatorial optimization(More)
Based on Geography Information System and Virtual Reality technology, a new system of collaborative urban planning and design is established by publishing the future urban developing and planning information in the urban government Website. With the help of the plug-ins supplied by the system, the citizens concerning with public affairs can interact easily(More)
