ABSTRACT: Fracture tests on two high-performance concrete for pavements were performed using the wedge-split test. The results allowed perceiving same specific fracture energy both concrete. However, crack opening during as well characteristic length of materials resulted in roundly distinct behaviors terms brittleness. Previous fatigue studies concretes are then fairly readdressed pointing out...

We present a simple, yet highly accurate, spam filtering program, called SpamCop, which is able to identify about 92% of the spams while misclassifying only about 1.16% of the nonspam e-mails. SpamCop treats an e-mail message as a multiset of words and employs a na’fve Bayes algorithm to determine whether or not a message is likely to be a spam. Compared with keyword-spotting rules, the probabi...

With the development of economic construction, underground space development continues to move towards the deep. "More, long, big, deep," will be the general trend of the development of underground engineering in the 21st century. Rock burst is a kind of sudden geological disasters with a higher frequency in deep tunnel construction. Rock burst prediction has very important significance for the...

Previous work on speech-to-speech translation has su ered from problems of brittleness and low quality (rule-based approaches), or from excessive data requirements and linguistic ine ciency (analogical or example-based approaches). In this paper, we present a probabilistic approach to analogical speech translation, and describe its integration with linguistic processing. The evaluation results ...
