This paper describe the relationship between C++ templates and partial evaluation. In C++, templates were designed to support generic programming, but not deliberately provided the ability to perform compile‐time computations and code generation. These features are completely deliberate, and as a result their syntax is ill at ease. After a review, these features in terms of partial evaluation, a much simpler syntax can be achieved. In C++, it may be regarded as a two‐level language in which types are first‐class values. Template instantiation resembles an offline partial assessor. In this paper, we explain groundwork in the direction of a single mechanism based on Partial Evaluation which unifies generic programming, compile‐time computation and code generation. The language Catat is introduced to demonstrate these ideas.
In the present work we studied the fabrication of ferroelectric film as PLZT by the sol-gel technique, and the birefringence optical property induced by the external voltage is measured by the electro-optic modulated ...

Identification and detection of the community structure is fundamental and important problem for the analysis of complex network. To detect community structure precisely, a new community detection algorithm was designed based on genetic algorithm and modularity density D. The algorithm does not need any prior knowledge about the number of communities, requires no arbitrary convergence or abruption criteria, and can generally find the global optimal solution. Genetic algorithm for detecting communities in complex networks, based on optimizing network modularity density was presented here. The algorithm was illustrated and compared with GN algorithm by using classic real world networks. Optimizing modularity density D not only can resolve detail modules but also can correctly identify the number of communities. Experimental results show the method can reveal community structure more precisely than traditional approaches. According to the definition of community in a strong sense, the nodes in experimental result which have more connections within the community than with the rest of the graph are more than the other partitions.
