The concrete design is to present a new solving model for the workflow exceptions by connecting ECA rules with transaction conception in database field, which analyses and utilizes the advanced transaction characteristics of workflow and is represented by nested transactions. This workflow exception handling model strengthens the connection with ECA rules and can effectively solve the workflow execution exceptions. The nested transaction workflow exception handling strategy and method based on ECA rules, compared to the traditional workflow exception handling frame, can better improve the effect of workflow exception handling.","PeriodicalId":393802,"journal":{"name":"2010 International Forum on Information Technology and Applications","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126473781","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 answer to a continuous query is continuously produced over time unless stopped artificially. During an executed continuous query, the run environment changes continuously, meanwhile some properties of data stream itself change too, such as input rate, selectivity of operators and execute time and so on. In order to adapt the continuity of queries and variability of system environment and date itself during continuous query, this paper presents a query plan optimization and migration strategy based on multi-factors and gives corresponding algorithm. Experiments have proved that this optimization and migration strategy ensures output results correctness and time sequence, meanwhile validly increases throughput and output rate and reduces output time latency.","PeriodicalId":393802,"journal":{"name":"2010 International Forum on Information Technology and Applications","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128876652","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 advent of Internet and Web technologies has enabled organizations and individuals all over the world to place enormous quantity of multimedia data on the Web. One approach to make use of these distributed, heterogeneous data and application systems is to apply the object-oriented technology and “wrap” them as distributed objects. These distributed objects can then be used as learning assets to compose learning objects for instruction and training purposes. This paper proposes how to aggregate and sequence of small granules of learning objects to form reusable composite learning objects, and a dynamic Learning Process for learning object registration, management, delivery and assessment.

With this way, concurrent product development process can be optimized, and product development cycle can be cut down. During research of overlapping coupling tasks, sequence of upstream and downstream is one of the most important factors to influence the number of iterations, the quantity of exchange information between tasks, the period of development, and the cost from development process. The process model of overlapping coupling tasks is built with structure design matrix. It can simulate the period of concurrent product development process, and get the duration of iteration process. Based on the process model, Gaussian elimination solution and iteration character of coupling tasks are taken into account, and the method to decide the upstream downstream sequence of overlapping coupling tasks is developed. Finally, the method is validated by an engineering example from a certain type of Turbochargers’ development project.","PeriodicalId":393802,"journal":{"name":"2010 International Forum on Information Technology and Applications","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124378686","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 noteworthy that the organization structure only influences the enterprise’s non-financial performance but not the financial performance. Besides, IT capabilities is one of the important factors which cause the change of the characteristics of organization structure. The conclusion indicates that the changes in organization structure should not only be taken seriously, but also be promoted actively.

Specially, we use two concepts: extension of T-meshes and spline spaces with homogeneous boundary conditions. In the dimension analysis, the important technique is linear space embedding with the operator of mixed partial derivative, which embeds the space of higher order into the space of lower order. Similar with the discussion of the dimension of biquadratic spline spaces over T-meshes, the necessary and sufficient conditions are described by the operator. Using the characteristic of T-meshes, we can reduce the number of conditions. With this method, a dimension lower bound of bicubic spline spaces over regular T-meshes can be provided. It is only depends on the topology of the T-meshes.","PeriodicalId":393802,"journal":{"name":"2010 International Forum on Information Technology and Applications","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116683007","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}
