In audio robust watermark algorithm, watermark is embedded in transform domain by using the speediness, simplicity and multi - resolution of wavelet transform. when extracting watermarking, the audio is decomposed by single - level discrete 1 - d wavelet transform, and watermarking is extracted by ica based on kurtosis maximization. this method ’ s computational cost is low
音頻水印利用小波變換快速、簡單和多解析度的特點來嵌入水印，提取的時候，先對觀測音頻文件進行一級小波分解，然後用基於最大峰值的ica方法進行水印提取，這種方法避免了其他盲源分離方法必需的求逆運算，所以計算量小。 -
A concept - based approach is expected to resolve the word sense ambiguities in information retrieval and apply the semantic importance of the concepts, instead of the term frequency, to representing the contents of a document. consequently, a formalized document framework is proposed. the document framework is used to express the meaning of a document with the concepts which are expressed by high semantic importance. the framework consists of two parts : the " domain " information and the " situation background " information of a document. a document - extracting algorithm and a two - stage smoothing method are also proposed. the quantification of the similarity between the query and the document framework depends on the smoothing method. the experiments on the trec6 collection demonstrate the feasibility and effectiveness of the proposed approach in information retrieval tasks. the average recall level precision of the model using the proposed approach is about 10 ? higher than that of traditional ones
為了獲取詞語在文章中的語義權重，解決詞語的同義、多義模糊問題，提升信息檢索的效率，提出了一種基於概念的檢索模型，模型中設計了一種形式化的文本內容表示框架，框架由2部分構成:文章的"領域"以及"情景與背景"信息，並由概念（形式化語義）加以表示.同時，提出了提取該概念框架的方法，給出了用於框架與檢索要求間匹配的兩階段平滑演算法.實驗表明，在trec6提供的小規模語料集下，採用所提出方法的信息檢索模型與傳統模型相比，平均召回準確率提升了約10 ? ，效果顯著，充分說明了基於本文描述方法構建的、以概念作為處理中介的信息檢索系統的有效性和可行性 -
The downstream processing conditions of g lucidum polysaccharides and flavone were studied and the extracting technique routes of these were set up. with the g lucidum polysaccharides and flavone as the " monarch drug ", feng shen ling capsules have been developed with radix astragali, radix salviae miltiorrhizae and radix scrophulariae as the " principal drug ". the capsule has been proved effective in enhancing human immunity function and decreasing the blood sugar level
