An improved classification method based on KMeans using HSV color feature is introduced in this paper. It is implemented by extracting three color features (hue, saturation, value) for K-Means clustering. Compared with the traditional K-Means clustering, the experimental results turn out that our proposed method is better than K-Means in classification accuracy and performance.
This article expounds the working principle and the merits of performance of the library computer room intelligent high heat transfer heat exchanger, analyses the running effects of the heat exchanger in place of the air-conditioner of the library computer room, Analysis showed that the use of the heat exchanger can reduce the working hours of the original air conditioner, extend its life, reduce...
Against trusted share distributed center (SDC) maybe dishonest or hard to find a trusted one, a secret sharing scheme (SSS) based on Blakley without SDC is proposed for the first time. By using secure scalar product protocol in secure multi-party computation, a secure multi-party vectors rank with low communication and low computation complex is designed. The SSS is based on this protocol, and it...
Wireless sensor networks are distributed networks in the way to form wireless self-organization, using a large number of sensor nodes densely deployed in a specific area to monitor external data collection. Positioning accuracy of node becomes the determinants of the data reliability. In this paper, the node of wireless sensor network is located using the algorithm of distribution estimation to enhance...
The paper puts forward a new graphical representation of DNA sequences -- H curve, gives the definition of H curve and the relationship between H curves and represents mitochondrial DNA sequences by H curve for the first time. Through calculating the distance of H curve compressed to get the distance matrix of mitochondrial DNA of eight species, then use Kruskal algorithm to construct the DNA sequence...
As the existence of objective and subjective factors in developing software, changes in requirements is inevitable, often lead to changes in program modules also. Because of correlation among program modules, to modify a module may lead errors to related modules. Put forward to establish association diagrams of modules, and use methods of traversal of graphs, to fast track, positioning error or affected...
There are many problems in the present research of teaching and application of E-Learning, such as theories separated, theoretical basis indistinct, technique used indiscriminately, lack of interaction, knowledge extension short and reflection insufficient, etc. So the ideal effect of knowledge extension, based on modern instructional theories, could not be reached. Focused on these problems, combined...
This article analyses the basic concept of E-Learning instructional design, proposes the theoretical basis of E-Learning instructional design, indicates Four Different Learning Theories to provide favorable theoretical basis for E-Learning from different aspects and gets different functions, on the basis of the basic theory of instructional system design from the E-Learning concept. The learning theory...
Nowadays the various understanding of the concept of multimedia has a great influence on the study and application of multimedia. In order to improve the understanding of the concept of multimedia, this paper probes into the essential meaning of multimedia through the analysis of its word structure, the internal properties of its concept, historical background of its origin and its essential properties.
This article analyzes E-Learning teaching design's basic instruction, design principle and design core based on the acknowledge of E-Learning teaching design's concept and connotation, constructing a model of E-Learning teaching system, which takes Web curriculum instruction system as an example and guided by constructivism. And it points out interactive E-Learning web curriculum system usually contains...
In the present research of teaching and application of e-learning, there are many problems, like theories separated, theoretical basis indefinite, technique used indiscriminately, interaction lacked, extension of the knowledge and dialectical thoughts insufficient etc. Therefore the ideal effect of knowledge extension could not be reached based on modern instructional theories. Focusing on the problems...
