We propose a novel problem to simplify weighted graphs by pruning least important edges from them. Simplified graphs can be used to improve visualization of a network, to extract its main structure, or as a pre-processing step for other data mining algorithms. We define a graph connectivity function based on the best paths between all pairs of nodes. Given the number of edges to be pruned, the problem...
Based on the test about compression-rebound properties of material bed, there are three zones in roller mill. The movement of material bed between two rollers in roller mill has been analysed. The pressure distribution equations in every zone on the roller's surface have been derived. The stress in roller is important for roller's failure analysis and the life estimation. But it depends on load, structure...
This paper is aimed at studying the marketing intelligence that affect customerpsilas experiential value in the restaurant chain industry. A structural equation model is proposed, incorporating customer characteristics, productspsila features, service quality, environmental ambience, traffic profile, and reputation as antecedents and components of consumer experience, to measure experiential value...
T-wave alternans (TWA) is a variation in the amplitude or morphology of the T wave of the beat-to-beat ECG which provides a noninvasive and clinically useful marker for the risk of sudden cardiac death (SCD) caused by life threatening arrhythmias. Detection of beat-to-beat microvolt fluctuation of the T wave has been made possible with the use of advanced signal processing techniques and high-resolution...
Based on the fuzzy classifying approach, the paper puts forwards a diagnosis algorithm of Back-propagation Neural Network. For some complexity environments, the traditional Back- propagation Neural Network has some limitations on classification. The paper applies fuzzy model on Neural Network structure, by using classifying variance and energy function to adjust the convergence of the Neural Network...
Knowing type of an uncharacterized membrane protein often provides a useful clue in both basic research and drug discovery. With the explosion of protein sequences generated in the post genomic era, determination of membrane proteins types by experimental methods is expensive and time consuming. It therefore becomes important to develop an automated method to find the possible type of membrane protein...
With the establishing of the idea that enterprises center on customers and development of the network technology, building an effective CRM system will be very important. CRM through data mining can get more efficiency in acquiring new customers, increasing value of existing customers and retaining good customers. At the same time, the data of data warehouse will offer the best data resource for the...
