Nevertheless, the dominant memory occupier is the first term, which still uses relatively big table. An improved method based on differential decomposition was brought forth aiming at relieving the problem, and hyperbolic tangent sigmoid function was implemented on FPGA using the improved algorithm. Experiment results showed that 17% to 30% of memory was saved after improvement.","PeriodicalId":293382,"journal":{"name":"Proceedings of 2nd International Conference on Information Technology and Electronic Commerce","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122388600","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}

However, the authentication of this protocol just derives from HTTP digest authentication, which has been demonstrated insecure in the open network. Recently, Arshad et al. proposed an improved mutual authentication scheme based on ECC and claimed that it's secure enough. In this paper, however, we point out that their protocol still could not resist offline password guessing attacks. Furthermore, we propose an ECC-based mutual authentication and key agreement scheme to overcome such a security problem. Also, an analysis of it is provided to indicate that compared to Arshad et al.'s scheme, this scheme reduces twice hash operation and is more secure with reasonable computation cost.","PeriodicalId":293382,"journal":{"name":"Proceedings of 2nd International Conference on Information Technology and Electronic Commerce","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132828523","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}

This model first makes dimensional normalization of the behavioral residue data of the users and uses the decision tree ID3 algorithm to characterize the behavioral residue data of the users to check such data against the behavior authentication sets, so as to determine the credibility of the compliance of the user behaviors with the contract. User behaviors are dynamic and random, so this paper proposes the status deduction function of the random Petri network to analyze the credibility of the compliance of user behaviors with the contract. Then the credible degree is calculated to make quantitative assessment of the user behaviors' credibility. The simulation experiments indicate that this model is able to reliably assess user behaviors' credibility in the cloud computing environment and is a certain improvement in terms of accuracy and efficiency of credibility authentication compared with the traditional models.","PeriodicalId":293382,"journal":{"name":"Proceedings of 2nd International Conference on Information Technology and Electronic Commerce","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114027396","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}

This approach builds on linear prediction: calculating the mean of the fourth power of prediction error of backscattering amplitude. By analyzing the IPIX radar datasets, it is found that the prediction error's mean and variance of the range bin containing a small target is much smaller than that of other range bins containing only sea clutter. The range bin, in which a small target is contained, gets smaller prediction error than those bins in which only pure sea clutter is occupied. Upon this point, we detect the small target in sea clutter with small amount of priori knowledge. The experimental results show that the proposed method can effectively detect small target in sea clutter with better performance.","PeriodicalId":293382,"journal":{"name":"Proceedings of 2nd International Conference on Information Technology and Electronic Commerce","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123314216","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}

Because of the complexity of existing development tool and difficulty of implementing pen-based user interface, pen-based e-form only can be designed and implemented by the professional developers, which make it difficult to adapt to the changing user requirements. It is a good method to solve the above problem to develop a software programming tool which supports end users to design their own software. Therefore, the paper systemically searches the end-user programming tool for pen-based e-form software, and details its software structure and component.

Although this technique can provide rich and accurate environment information, however, it is too time consuming and not practical. To solve that problem, a local SURF based 3D reconstruction algorithm for mobile robot is proposed, which includes three main steps: first, the posture variations were captured from posture sensor and milemeter, and then the initial transition matrix was established; second, when finishing extracting features of the previous frame, searching areas were computed from the initial transition matrix and search radius; last, final transition matrix was computed according to the matching points.
