Utilizing NIPGA,an experimental device for cement raw material analysis has been developed,with a 2.5 MeV D-D neutron generator,BGO detector and 2048 MCA.A linear regression was developed for calculating the data.A 6-month on-site application of the system showed that the CaO,SiO2,Fe2O3 and Al2O3 analysis results agreed well with chemical analysis,within 0.40%,0.40%,0.50% and 0.50%,respectively.

MicroRNAs are a class of small, single-stranded RNAs which are produced by non-protein-coding RNA genes with a length of 21-29 nt. They regulate the expression of protein-encoding genes at the post-transcriptional level and the degradation ofmRNAs by base pairing to mRNAs. Mature miRNAs are processed from 60-90 nt RNA hairpin structures called pre-miRNAs. At present, most of the machine learning computational methods for pre-miRNAs prediction are based on two-class SVM and use structural information of pre-miRNA hairpins. Those methods share a common feature that all of them need a negative dataset in the training dataset and feature selection in both training and testing dataset. In order to avoid selecting false negative examples of miRNA hairpins in the training dataset which may mislead the classifiers, we presented a microRNA prediction algorithm called MirBio based on miRNAs Biogenesis which is trained only on the information of the positive miRNAs class to predict miRNAs. It can predict both pre-miRNAs and miRNAs and get a relatively satisfying result in this study.

The road to a successful introduction of vehicular communications has to pass through the analysis of potential security threats and the design of robust security architecture able to cope with these threats. Ad hoc networks are a new wireless networking paradigm for mobile hosts. In this paper, we designed a framework of intelligent transport system. The main task of the road condition information transferring module is deal with the information exchange of the car inside, car to car and car to road. Vehicular networks are likely to become the most relevant form of mobile ad hoc networks. In the ITS of this paper, we concern the security issues of VANETs from some aspects and provide the appropriate solving measures. To make sure the ITS can be used under the security pattern.

In this work, a framework of multimedia retrieval system basing on the MPEG-7 standard as information schema will be proposed. It provides a content-based retrieval method which uses MPEG-7 Metadata description. The high efficient of multimedia retrieval as well as the data management is an important issue. Tending to query the multimedia data, the previous text-based retrieval system is too difficult for users to specify the data they want. So it is necessary to query multimedia itself or metadata based document Our retrieval system can accept multimedia examples or metadata-based documents. The annotation and feature extraction of multimedia data will be discussed in this paper, and the organization of source multimedia data as well as other data structure for managing and storing will be discussed too. At the end a new method of metadata representation is proposed.
