Under cloud environment, cloud service providers need to predict non-stationary workloads, and base prediction results to plan and execute fault-tolerance strategies in advance so as to ensure services' ability in fault-tolerance. High prediction precisions in services' workloads improve effectiveness of strategies such that service's fault-tolerance is advanced. In this paper, we propose a hybrid...
This paper proposes a novel approach for detecting groups of people that walk “together” (group mobility) as well as the people who walk “alone” (individual movements) using wireless signals. We exploit multiple wireless sniffers to pervasively collect human mobility data from people with mobile devices and identify similarities and the group mobility based on the wireless fingerprints. We propose...
We present here a browser-based application for visualizing patterns of connectivity in 3D stacked data matrices with large numbers of pairwise relations. Visualizing a connectivity matrix, looking for trends and patterns, and dynamically manipulating these values is a challenge for scientists from diverse fields, including neuroscience and genomics. In particular, high-dimensional neural data include...
In this paper , basing on the measurement of the innovations and the default risk indicators, we take default risk as the induced variable, and take R&DR, innovations, corporate size, system risk and asset-liability ratio as the dependent variable, to empirical analysis the correlation among the listed company's default risk ,innovation performance and other variables. By the empirical analysis...
Generally the surround space constant of Retinex's center/surround algorithm is an empirical value that is between 25 and 250, and it is of small images. For the larger engineering images, how much should the parameter value be? In addition, in this algorithm, convolution is an operation whose efficiency is very low. It is a bottleneck that has impact on this algorithm's application in image engineering...
In this paper, we study the routing and wavelength assignment (RWA) problem in a semi-dynamic scenario where rearrangements are conducted in a series of sessions after traffic demands vary. Unlike pure static RWA problems, each rearrangement scheme must consider established lightpaths in the previous session. A novel formulation of the WDM network rearrangement problem is used to minimize rejected...
