We demonstrate a procedure of contaminant-related failure analysis, which identifies where the contaminant sources are by looking for the matched characteristics in a contaminant library. As a result, an expandable contaminant library with over a half thousand of samples is created along with an indexing searching engine to largely reduce the time-consuming identification. With this system, we can...
In order to overcome """"semantic gap"""" between bottom features and high-level semantic in the image retrieval, this paper introduces the echo state network to strengthen the mapping between the high-level vision content and the bottom visual feature and designs a feedback category screening strategy. We extract the feature of the queried image and get the...
It is the basic way to enhance service ability to predict customer behavior in the process of E-commerce activities. Through applying temporal description logic (TL-ALCF) in describing the rules of time-dependent customer behavior change, this article puts forward a method in acquiring algorithms through improving the temporal correlated rules of the FP-tree(frequent pattern tree), and further constructs...
Description Logic is the logical basis of Semantic Web knowledge representation and reasoning, it has strong capacity of expression, but it is not applicable to uncertain knowledge representation and reasoning. Horn rule is a proper subset of first-order predicate logic, which can be determined, its implication expression makes the description closer to a natural description of the problem, but it...
At present, the Database Application System Interface and access logic are all auto-generated by dragging the data table object from the database server view in the database application system development environment, or by linking the well-designed interface controls with the fields of the table in the database. A new direction of Interface Controls Descriptions (ICD method) is proposed, which is...
The traditional role-based access control mechanism controls the user to access the resources based on the roles, simplifying security management. However, it cannot effectively provide semantic understanding and reasoning due to lack formal mechanisms. A new Description Logics-based access control model is presented, it applies Description Logics to realize a formal description of the relationship...
Cache utilization is critical to performance in a chip-multiprocessor(CMP) system. A typical cache hierarchy in a CMP contains per-core private cache and a large shared last-level cache. How to schedule tasks to improve cache utilization is challenging. In this paper, we propose a cache-aware scheduling policy which improves cache performance by considering data reuse, memory footprint of co-scheduled...
In past twenty years, as the rapid growth of Internet application, network education has grown a main part of current education. At the same time, semantic-based network educational resource became an important research field in computer education technology and AI. So far, however, there is a serious of bottlenecks in the progress of their applications, e. g. the criterion of web resource is not...
