The DNS server will often be attacked through various means, which will lead to our DNS server's low efficiency or even make the DNS server not to provide service of DNS analysis normally and correctly. DNS detection is just to detect whether these accusations happen or not in time. There are many methods for anomaly detection of DNS server, for example, the method based on similarity, the method based on entropy and so on. We will research the combination of the two methods and then realize it. This will improve the monitoring effeciency.

In order to achieve the simulation of the external offshore environmental conditions in the wind power generation system, a wind speed model and a tower load module was built by simulink for calculating the wind load and current load on the wind rotor and tower load and introduce the ice load briefly. The simulation results show that the model can not only show positive responses to the actual wind speed, but also provide the correct source parameters for the study of wind power generation analog systems. Load model has directive significance for the calculations of the offshore wind turbine load.

The cab suspension system plays an important role in vehicle ride performance. In order to fully assess the ride comfort characteristics of a heavy vehicle with three diff erent structures of cab suspension system, Road tests under various conditions were carried out. And the vibration characteristics of the three diff erent structures of cab suspension system using front hydraulic and rear airbag with single height valve, 4-point airbag with single height valve and 4-point airbag with double height valve control were respectively analyzed. In additional, the test data was processed in frequency domain. The results show that the ride comfort of the cab suspension system of 4-point airbag with double height valve control is better than that of the other two cab suspensions.

In this paper, we apply the k-climax neighbors (k-CN) policy derived from the Bayesian Ying-Yang (BYY) learning framework to Viterbi decoding for Hidden Markov Model based large vocabulary mandarin speech recognition, to adaptively obtain a more precise state decision boundary in the decoding phase. When calculating the posterior probability for each state on a given frame, k Gaussian components from these states are selected by the k-CN policy as the most reliable descriptions, which make the decision boundaries among the competitive candidate states more precise. The experimental results show that a 2.1% relative reduction of the character error rate is achieved on Hub-4 test by adopting the proposed approach.

In order to solve the existing curriculum resource issues on the internet, such as lack of semantic, simple resource structure, the ineffective share of curriculum resources. Protégé tools are used to construct domain ontology of curriculum, and to put forward a curriculum resource management framework based on ontology. In this framework, the curriculum ontology is used to describe the curriculum resource, so as to make curriculum resources achieve the shared and mutually operation on the layer of semantic. Besides, with the help of the development tool “Jena”, ontology storage and query are supported, to ensure the quick finding of learning resources and to promote effective learning...

A novel image fusion algorithm based on wavelet lifting scheme is presented. The lifting scheme is a new idea of constructing wavelets and has several unique advantages over conventional convolution-based wavelet transform. It allows for an in-place implementation of wavelet transform and reduces computation time and memory requirement greatly. So in this fusion algorithm, the lifting wavelet transform is employed to decompose and reconstruct images to realize fast image fusion. Meanwhile, a new local feature-based fusion rule is put forward to improve fusion quality and extract all significant features from multi-source images. Extensive experiments on the fusion of registered SPOT Panchromatic/multi-spectral images, multi-focus digital camera images,and medical MRI/CT images have been performed. Finally, visual judgment and several objective evaluation criterions are taken as the means of assessing fusion performance. The experimental results show that the new approach is very effective and is able to fuse multi-source images.
