The process is tolerant to using lossy bit-rate reduction based formats such as mp3 as well. To extract digital watermarks, we propose to use cepstral transformation and correlation receiver that differs from canonical models known from the communication theory. We use modeling techniques to calculate errors frequency and to optimize watermarks embedding parameters. 002:004.056 steganography digital watermarks information security reverberation https://infocom.spbstu.ru/article/2012.30.5/

Problems of software acceptance testing automation in behavior driven development Paper is focused on problems of acceptance tests automation in behavior driven development (BDD). We illustrate basic ideas of BDD by some development and testing examples. Special attention is being paid to difficulties of converting customer-side test stories into executable unit tests. We analyze process of marking up of test stories by a QA engineer for their subsequent automated conversion into the corresponding test classes and test methods. We define tasks for developing further tools aimed to support acceptance tests automation and to improve BDD based test story language. 004.413:004.414.3:004.415.53 software engineering software testing agile practices quality analysis https://infocom.spbstu.ru/article/2012.30.13/
