How does a search engine company decide which advertisements to display for each query to maximize its revenue? This turns out to be a generalization of the online bipartite matching problem. In this paper, search engines decide the strategy to allocate resources with an advertiser credibility factor under budget constraints. Based on the optimal algorithm, which is the notion of a trade-off revealing...
Utilizing graph analysis models and algorithms to exploit complex interactions over a network of entities is emerging as an attractive network analytic technology. In this paper, we show that traditional column or row-based trace analysis may not be effective in deriving deep insights hidden in the storage traces collected over complex storage applications, such as complex spatial and temporal patterns,...
A new time-delay estimation method based upon Cubic spline interpolation and Area bary center algorithm that is well suitable for determining the time-delay between two noisy band-limited signals is introduced. Unlike conventional correlation algorithm, the new approach has the ability to optimally estimate any non-integral sample delay only using Cubic spline interpolation and Area bary center algorithm...
Conventional methods used to analyze storage workloads have been centered on relational database technology combined with attributes-based classification algorithms. This paper presents a novel analytic architecture, GraphLens, for mining and analyzing real world storage traces. The design of our GraphLens system embodies three unique features. First, we model storage traces as heterogeneous trace...
We studied various psychiatric attributes in the categories of depression, anxiety and insomnia on 208 patients with liver cirrhosis, 61 patients with non-cirrhosis chronic diseases, and 60 healthy people. A set of psychiatric attributes were found to be uniquely associated with cirrhosis. Literature shows that these attributes are related to some mechanisms underlying liver cirrhosis, such as zinc/selenium...
Constructed wetlands (CWs) have proven to be a promising treatment alternative for developing countries. Recently attention has been focused on the ability of CWs to reduce human pathogens in wastewater. In this study, indicator microorganisms (Escherichia coli) and pathogens (Salmonellae) were analyzed from a full-scale surface flow constructed wetland situated in China. The results showed that for...
The adsorption of two dyes, namely, cationic red X-GRL and cationic brilliant blue RL onto natural attapulgite were studied, and adsorption mechanism was focused on from the view point of kinetics. Kinetic analysis showed that the adsorption processes of two cationic dyes on natural attapulgite obey the pseudo second-order model. The adsorption capacity of dyes was raised with temperature, but the...
