According to the noise and overlapping characteristics of agricultural irrigation water quality monitoring data for the comprehensive evaluation may bring about the boundary fuzzy problem. This paper proposes an improved Genetic Algorithm (GA) to avoid premature convergence, the global optimal solution of the function of the Projection Pursuit (PP) function is used as the comprehensive evaluation...
With the rapid increasing of smart phones and their embedded sensing technologies, mobile crowd sensing (MCS) becomes an emerging sensing paradigm for performing large-scale sensing tasks. One of the key challenges of large-scale mobile crowd sensing systems is how to effectively select the minimum set of participants from the huge user pool to perform the tasks and achieve certain level of coverage...
With the rapid increasing of smart mobile devices and the advances of sensing technologies, mobile crowd sensing (MCS) becomes a new popular sensing paradigm, which enables a variety of large-scale sensing applications. One of the key challenges of large-scale mobile crowd sensing systems is how to effectively select appropriate participants from a huge user pool to perform various sensing tasks while...
Special Treatment (ST) is a particular regulation for the exchange to prompt the risk to investors. Since ST count data are discrete, traditional Orthogonal Least Square method cannot get better goodness of fitting. However, Poisson regression is appropriate to be used to analyze discrete data. In addition, once it is over-dispersed, Negative Binomial (NB) regression model is more suitable. In this...
Spatial data warehouse has the ability of integrating the mining geological hazard data, and gives the support of complex data analyzing and high-level decision-making. In order to construct such a mining geological hazard multi-dimensional data warehouse, based on the introduction of several concepts of data warehouse, the paper proposed the formal definitions of the dimension, the dimension hierarchy,...
Based on the tunable diode laser absorption spectroscopy (TDLAS) gas detection system, simulation models are built up using the dynamic simulation tool. The second harmonic signals of CO with six different concentrations are obtained depending on the simulation models. Regression coefficient is obtained by overall second harmonic least squares fitting of standard second harmonic spectrum signal of...
The concept of batch processing in workflow is to model and enact the batch processing logic for multiple cases of a workflow in order to optimize business processes execution dynamically. To achieve this goal, it is important to define a dataflow operation language to compose and decompose the data in multiple cases of a workflow vertically. Though our previous work has preliminarily investigated...
A method of fault location is presented which is based on the traveling-wave scheme for rural MV power networks. There are two steps in this method, the first step is to determine the fault section, and the second is to find the fault point. When a single-phase-to-earth fault happened, injecting a narrow pulse signal with high voltage and detecting the wave signal returned back from the line, we analyze...
