There are theoretical teaching and practical teaching in this course. This paper introduces a new teaching method that is called an embedded teaching method. This method is applied to the data warehouse course successfully. Firstly, the ideas of this method are presented. Some associative knowledge in other courses is integrated to the data warehouse course. So teachers impart a whole knowledge structure and system to students in theory and practice. Then specific teaching steps are shown with examples. In the end of the paper, advantages of this teaching method are summarized.","PeriodicalId":393802,"journal":{"name":"2010 International Forum on Information Technology and Applications","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121835861","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Observed from the network layer and transport layer, these attacks may not contain significant malicious activities, and generate abnormal network traffic. However, traditional security techniques usually detect attacks from those two layers. Although some security techniques can detect some application layer attacks, these techniques can only detect some known attacks, and these techniques can’t detect the unknown or novel attacks happened on application layer. In theory, application layer anomaly detection can detect the unknown and novel attacks happened on application layer, so the research of application layer anomaly detection is very important. This paper presents a new application layer anomaly detection method which based on HSMM. The experimental results show that this method has high detection accuracy and low false positive ratio.","PeriodicalId":393802,"journal":{"name":"2010 International Forum on Information Technology and Applications","volume":"2015 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128581378","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Neglecting noise, the seismic record is changed from time domain to frequency domain with STFT in order to transform the common seismic model to the basic ICA model. By applying FastICA algorithm, reflectivity series and the seismic wavelet can be produced in frequency domain and changed back to the time domain subsequently. The model and real seismic data numerical examples all show the algorithm valid. The advantage of this new method is to inverse blindly the wavelet and the reflectivity effectively with no assumption of Guassality and whiten noise to reflectivity, and no assumption of minimum phase to seismic wavelet.

However, accurate instantaneous channel knowledge at the transmitter is costly and may be difficult to acquire. When the receiver side has the perfect channel state information, the capacity can be found with the transmit covariance which involves to find the optimum transmit directions and the optimum power allocation polices. Most recent work has been done on the MIMO capcity with channel side information, channel mean or channel covariance. But sometimes the trasmitter can get the channel mean and channel voariance simultaneously. this paper will study the optimum power allocation for maximizing the MIMO capcity both with the channel mean and channel covariance.
