In order to increase the efficiency of raster image storage, a block file directory tree (BFDT) framework is introduced in this paper as a new index structure of raster blocks. Through changing the container of raster blocks from the database to the file system, and depends on the file system's storage advantage of high efficiency, the BFDT framework improves the storage method used by GeoRaster....
Performing the function of encapsulating the whole discourse, discourse topic is usually considered as the center of the discourse. However, the representation form of discourse topic has not been agreed upon due to the elusive nature of the notion per se. Some people view discourse topic as an entity; others regard it as a question; still others as a proposition or even as an unnecessary form. This...
Van Kuppevelt's approach to discourse structure emphasizes that topicality is the general organizing principle. His discourse structure consisting of MAIN STRUCTURE and SIDE STRUCTURE has been applied to conversations and discourse segmentations rather than expository essays. In this paper two discourse structures of expository essays are proposed in Van Kuppevelt's framework. The proposed structure...
In large-scale distributed systems, runtime monitoring is an important means to check whether the system complies with its intended behavior. This paper proposes a framework named Mega that supports the development and running of monitoringenabled distributed software systems. In our framework, a dedicated language is introduced to describe where and what should be monitored at runtime, which can...
In order to explore whether the Chinese retrospective labels demonstrate the same features as the English counterparts, this study has compared 30 Chinese newspaper articles with 30 English ones, all of which are argumentative essays. The results show that different from the English counterparts, the Chinese retrospective labels usually convey non-evaluative old information and appear in pre-verbal...
COTS component evaluation is one of the most important steps in component-based development. Enforcing the coding standard within the coding phase is one important aspect for the quality of safety-critical software. This paper addresses the problem of carrying out COTS component evaluation of its compliance to the coding standard in case when only the executables with neither source code nor debugging...
Large-scale distributed monitor networks are in face of the challenge of tremendous data communication costs due to the resource restriction. Prediction models can be used to reduce communication cost over the networks. A framework is proposed which provides a mechanism to maintain adaptive prediction models that significantly reduce communication cost over the distributed environment while still...
This paper discusses the teaching innovation of the college physics under the network circumstance in three facets, such as the teaching materials, a multifunctional teaching platform and the teaching ideas and methods. The college physics teaching under the network circumstance is one of good ways to improve the quality and efficiency of teaching in the modern times.
In this paper, we have investigated the magnetic properties of non-doped 4H-SiC surface by using density functional theory (DFT) calculations. For polar pure surface (0001) direction , there will be spin-polarized, and C-terminated or Si-terminated surface have no spin-polarized. We also check the kinds of defect intrinsic properties. This study of defect states suggests the existence of defect-induced...
