To simulate user's behaviors more realistically, this paper proposes a novel hierarchy testing framework and method for Web applications performance. It extracts the access information from Web log files and builds a hierarchical structure model (HSM) by statistical analysis, obtains the test path with higher probability based on HSM model, and tests Web applications performance by using this path...
Studies on quality evaluation of coordinate transformation have not yet to comprehensively investigate the simulation ability and reliability of a transformation. This paper presents a comprehensive quality evaluation system (QES) for coordinate transformation that includes the testing of reliability and simulation ability. The proposed QES was used to test and evaluate transformations using typical...
This paper deals with the simulation problem of crystallization processes. The dynamics of crystallization processes are governed by hyperbolic partial differential equations. We propose to simulate the processes in the one-dimensional size case using the method of characteristics. We observe that the method of characteristics has no numerical diffusion compared with the finite difference method....
For the given multiple patterns and a text string, firstly, a perfect hash function is constructed, the patterns are transformed into the unique pairs of integer values in parallel by the perfect hash function, the corresponding integer values are stored in a global hash table, and a recursion expression for computing hash function value of the signatures of each sub-string of text is also proposed...
