It is based on the tangent spaces of data points that HLLE defines and calculates the Hessian matrices of data points. However, the proof presented in this paper shows that the space commonly used to calculate the Hessian matrix of a data point in HLLE algorithm is not the tangent space of the data point, but the tangent space of the midpoint of the data point's neighborhood. When a data point is far away from the midpoint of its neighborhood, HLLE will break down. This defect of HLLE algorithm has never been pointed out in previous literatures. Based on this fact, an improvement to the original HLLE algorithm is proposed in this paper. The main idea of the improved HLLE algorithm is that the neighborhood of a data point must be chosen so as to make the midpoint of the data point's neighborhood as close to the data point itself as possible. The experimental results presented in this paper show that the improved HLLE algorithm outperforms the original HLLE algorithm on the manifolds such as Punctured Sphere, where the data are often unevenly sampled.","PeriodicalId":373152,"journal":{"name":"2012 IEEE International Conference on Automation and Logistics","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132507648","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}

For the 3IPFN, a novel weights-and-structure-determination (WASD) algorithm is presented to solve data approximation and prediction problems. With the weights-direct-determination (WDD) method exploited, the WASD algorithm can obtain the optimal weights of the 3IPFN between hidden layer and output layer directly. Moreover, the WASD algorithm determines the optimal structure (i.e., the optimal number of hidden-layer neurons) of the 3IPFN adaptively by growing and pruning hidden-layer neurons during the training process. Numerical results of illustrative examples highlight the efficacy of the 3IPFN equipped with the so-called WASD algorithm.","PeriodicalId":373152,"journal":{"name":"2012 IEEE International Conference on Automation and Logistics","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134322162","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}

In this article, the TMS320VC5416 is used to design and realize the encoder and decoder of LT codes. In order to improve the decoding efficiency, the redundancy process is introduced to remove the redundancies of code signals. As the computational burden and memory usage of the encoder and decoder increase rapidly with the encoding length, the feedback control signal is introduced to control the length of code signals. Positional coefficient storage mechanism of neighbors' list of the code signals is built to ensure the optimal use of DSP chip's memory resources. The simulation results show that the LT codes encoder and decoder based on DSP have good performance.","PeriodicalId":373152,"journal":{"name":"2012 IEEE International Conference on Automation and Logistics","volume":"114 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116447353","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}

It is shown that the time of estalishing output voltage is very short, and the recovery time of the output voltage is also short under sudden adding load and sudden unload.

Empirical mode decomposition (EMD) can decompose the nonstationary and nonlinear signals by sifting into a few intrinsic mode functions (IMFs) which represent a simple oscillatory mode of local data. However, the traditional bidimensional EMD (BEMD) has two drawbacks of the gray spots in IMF image and the slow computation speed. WEMD can solve such problems. Based on the characteristic of WEMD and local time/space-frequency analysis of structure multivector, the renovate technique of texture segmentation is also presented. Characterized by the local amplitude and the local frequency of every IMF component, the texture image can be segmented by k-means clustering algorithm. The subsequent experimental results indicate this method's effectiveness.","PeriodicalId":373152,"journal":{"name":"2012 IEEE International Conference on Automation and Logistics","volume":"303 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124327629","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}

Then we discuss how to deploy Hadoop in virtual machines which can be obtained from CloudStack by some means, then an algorithm to solve the problem that all the virtual machines which are created by CloudStack using same template have a same hostname. After that we run some Hadoop programs under the virtual cluster, which shows that it is feasible to deploying Hadoop in this way.
