In classifying samples by Gaussian clas-siier, the covariance matrix estimated with a small number sample set becomes unstable, which leads to degrading the classiication accuracy. In this paper , we discuss the covariance matrix estimation problem for small number samples with high dimension setting based on Kullback-Leibler Information Measure. A new covariance matrix estimator is developed, ...

We present a fast automatic reproducible method for 3d semantic segmentation of magnetic resonance images of the knee. We formulate a single global model that allows to jointly segment all classes. The model estimation was performed automatically without manual interaction and parameter tuning. The segmentation of a magnetic resonance image with 11 Mio voxels took approximately one minute. Our ...

in the procedure of designing an underwater vehicle or robot, its maneuverability and controllability must be simulated and tested, before the product is finalized for manufacturing. since the hydrodynamic forces and moments highly affect the dynamic and maneuverability of the system, they must be estimated with a reasonable accuracy. in this study, hydrodynamic coefficients of an autonomous un...

Train passenger door is the key system for operation and maintenance on urban rail train. In this paper, we analysis passenger door system of urban rail train working process and establish the mathematical model. Firstly, we use the method of parameter estimation to get physical parameters of doors on different working condition. Then fault diagnosis experiment is done to train passenger door w...

This paper introduces a method for predicting the likely behaviors of continuous nonlinear systems in equilibrium in which the input values can vary. The method uses a parameterized equation model and a lower bound on the input joint density to bound the likelihood that some behavior will occur, such as a state variable being inside a given numeric range. Using a bound on the density instead of...

The effects of rice harvest moisture content (HMC) on pasting properties were investigated. One medium-grain and nine long-grain rice varieties were plot combine harvested at different intervals from three locations in 2002. Rough rice samples were dried and milled under controlled conditions, the head rice yield was recorded, and the rice flour was analyzed for pasting properties. The peak vis...

The use of low air temperatures (79 to 93 °F) and relative humidities (19% to 68%) to dry thin-layer samples of rough rice to the desired 12.5% moisture content was investigated. Drying rates and durations and their effects on the quality parameters of head rice yield, color, and pasting viscosity of longand medium-grain rice cultivars harvested at 19.6% and 17.5% moisture contents, respectivel...
