Driver sleepiness is a hazard state, which can easily lead to traffic accidents. To detect driver sleepiness in real time, a novel driver sleepiness detection system using support vector machine (SVM) based on eye movements is proposed. Eye movements data are collected using SmartEye system in a driving simulator experiment. Characteristic parameters, which(More)
In this paper, we propose a feasible tool that uses a terahertz (THz) imaging system for identifying wheat grains at different stages of germination. The THz spectra of the main changed components of wheat grains, maltose and starch, which were obtained by THz time spectroscopy, were distinctly different. Used for original data compression and feature(More)
Outlier detection is an important research problem in data mining and image analysis. In this paper, the ideas in the PageRank algorithm are borrowed to construct a novel outlier detection method. In this method, three detecting stages are performed to detect three different types of outliers by using different detecting strategies. The whole process is(More)
An effective prediction for stored grain pests contributes significantly to pest control at the right time, and thereby reduces control cost and environmental pollution. In this paper, aiming at the deficiencies of the existing prediction models, a new prediction method for grain pests based on Cellular Automaton (CA) combining with environmental factors(More)
Terahertz (THz) spectroscopy and multivariate data analysis were explored to discriminate eight wheat varieties. The absorption spectra were measured using THz time-domain spectroscopy from 0.2 to 2.0 THz. Using partial least squares (PLS), a regression model for discriminating wheat varieties was developed. The coefficient of correlation in cross(More)
The field of grain logistics transport vehicle route has seen the development of a variety of mathematical techniques, and the practical application of these techniques has depended on the use of spatial information, such as regional allocation information of road network. Vehicle Routing Problem (VRP) is regarded as the key of grain logistics distribution.(More)
With regard to the distribution of the grain logistics, to analyze the structure and the function of the grain logistics information platform based on GIS. To provide an ideal solution according to the problem of the distribution of the grain logistics, the core modules were studied in this paper, such as the transportation vehicles and goods real-time(More)
A new method of grain moisture content measurement in granary is developed; it is based on the measuring principle and characteristics of microwave moisture content determination techniques. According to the relationship between the power attenuation, signal parameter variation and moisture content of grain when the microwave penetrates the grain, a model(More)
