Mobile Learning has become another very important complement to the traditional ways of learning after digital-learning. The development of the third generation mobile communication technology 3G provides a more adequate technical basis for mobile learning. How full and effective use of the third generation mobile communication technology to assist any kind of teaching and learning become an important research part of mobile learning. This article describes the 3G-based mobile learning project, where mobile device is used for educational activities. The main perspective in this article is in teacher training. We present strategies how mobile technology was used in teacher training and exerted the advantages of 3G mobile phones. The goal of these innovative pilot projects is to create flexible teaching solutions, which will enable the accessing of information with all kinds of devices, and to support learning in a variety of situations.","PeriodicalId":6397,"journal":{"name":"2011 Fourth International Conference on Information and Computing","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80722853","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}

The simulation results show that the strong shearing sections are concentrated in the zone between the top of wing and mixing chamber wall and the zone between long wing and short wing. The dispersive index is increased with the shearing action, directly proportional to the rotate speed. The axial distribution law of shearing is foundationally the same under different initial relative positions, but the shearing strength is different for that. The experimental results are fit to the simulation results. The dispersion degrees of carbon black are different by ±1 level for two rotors placed in different initial relative positions.","PeriodicalId":6397,"journal":{"name":"2011 Fourth International Conference on Information and Computing","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81130810","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}

Thus the accuracy and the generalization performance of the IKMRA can not be satisfied. In order to improve the precision and the generalization performance of the IKMRA, we proposed that each sample regression error be constrained besides the total regression error. We introduced the norm-r loss function and the slack variables in order to constrain each sample regression error, derived the iterative formula of corresponding gradient decent method and devised the corresponding algorithm. Experimental results show that our improved indefinite kernel machine regression algorithm (IIKMRA) is effective and feasible.","PeriodicalId":6397,"journal":{"name":"2011 Fourth International Conference on Information and Computing","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78050468","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}
