摘要:
The present invention provides a unique wave-trigon transformation (WTT) method for performing transformation process over a wave signal. The present invention also provides a pitch detecting method and apparatus for detecting pitch based on the WTT process as well as a sentence detecting method and apparatus for detecting a sentence in a sound signal based on the WTT process. The pitch detecting method and apparatus can effectively detect pitch in a sound signal. In the WTT process, an inputted wave signal (such as a sound signal) is transformed into a series of trigons, and an energy-width spectrum is formed using these trigons. For a sound signal containing voice, the distribution of trigons transformed from the sound signal has a certain pattern. By analyzing the pattern, whether a pitch is contained in the sound signal can be determined. In particular, existence of a pitch can be determined by determining and evaluating the periodicity of trigons in a candidate chained peak in the energy-width spectrum.

A method and device for clustering virus files is provided. The method involves statically analyzing binary data of virus files to be clustered, so as to obtain PE structure data of the virus files. Further, based on a comparison of the PE structure data, those virus files with PE structure data meeting a specific similarity may be categorized into the same category. The device may include a first data analyzing module configured to extract PE structure data of virus files to be clustered by static analysis of binary data of the virus files. A first clustering module of the device may compare the PE structure data and cluster the virus files having the PE structure data meeting a specific similarity into the same category. The solution may improve efficiency of clustering computer virus files, reduce resource consumption, and avoid the risk of virus infection caused by dynamically running the virus files.

A method for determining a suspect memory leak, including: sampling the throughput and memory usage of an application server; based on the sampled throughput, monitoring whether the throughput decrease continually, and based on the sampled memory usage, monitoring whether the memory usage remains stable within a predefined range; in response to a continual decrease of the throughput and the memory usage remaining stable within the predetermined range, determining that the application server is suspected of having a memory leak. Using the solution of the present invention can free an administrator of the burden of artificially identifying suspect servers, can identify a suspect server during runtime and further determine whether it actually has a memory leak.
