The semantic description of remote sensing image is a useful and meaningful task, which can help us to get a better understanding of the scene depicted in the remote sensing images and make better use of the remote sensing images. Nature language provides good solution for describing the semantic information of remote sensing images. Nature language description of a remote sensing image is to generate...
The reasons for the electromagnetic interference of the intelligent pole mounted switch controller were analyzed and its sources of electromagnetic interference were classified. Secondly, some common electromagnetic interference issues were introduced and intelligent controller EMC design principles were proposed from the circuit design, PCB board layout and routing aspect. Finally, testing principle...
This paper introduces an incremental closed frequent item sets mining algorithm, which is based on a shadow prefix tree to get closed frequent item sets. By the use of shadow technology this algorithm can avoid the cost of generating and testing of candidate subsets. Shadow prefix tree can find nodes by virtual node without generating all nodes. The experiment results show that this algorithm can...
A new psychological evaluation method was studied in personnel selection - drawing projection test, control test method was applied in this paper. In the simulation of recruitment scene, both drawing projection test and normal psychological evaluating scale were adopted to do psychological test for experiment group, and the test results were compared and analyzed. Analysis founds that drawing projection...
A Time Division Duplex (TDD) approach is demonstrated for voice communication in the environment of wireless sensor networks. The architecture of the Voice Wireless Sensor Networks (VoWSN) is presented and the hardware designing of Voice Node and Gateway Node are described in detail. Voice quality of different scenarios such as indoor, corridor, corner and outdoor are tested. It is resulted that good...
Today is the era of information and knowledge-based economy, the task of experimental education is to train talented persons with innovative spirit and high ability, packaging engineering experimental teaching platform is to meet this demand, which is supplement and perfection to the traditional laboratory teaching. Interaction design is the basis to built the experimental teaching platform, the quality...
It is a key factor for classifier-guided topical crawler to obtain labeled training samples. Recently, many such classifiers are trained with Web pages which are labeled manually or extracted from the open directory project (ODP), and then the classifiers judge the topical relevance of WebPages pointed to by hyperlinks in the crawler frontier. Though one can obtain labeled WebPages with comparative...
Contingency planning generates a preventable mechanism to maintain continuity of support for IT field. Several steps are needed in the process of constructing contingency planning to ensure the effectiveness and precise. These steps are organized not separately but logically and systematically. Method of software engineering is available for use. Rational unified process (RUP) is adopted and developed...
POSC4.5 is a one-class decision tree classifier with good classification accuracy which learns from both positive and unlabeled examples. In order to further improve the classification accuracy and robustness of POSC4.5, in this paper, we ensemble POSC4.5 trees by bagging, and classify testing samples by majority voting. The experiment results on 5 UCI datasets show that the classification accuracy...
