In this short paper, new properties of transition matrix were introduced. Eigen values for small order transition matrices are calculated in flexible method. For benefit of these properties applications of these properties were studied in the solution of Markov's chain via steady state vector, and information theory via channel entropy. The implemented test examples were promised for usages. Ke...

In this paper a new electromagnetic nondestructive system for inspection of train hollow axle is presented. The system allows to observe changes of vector AC fields in order to enhance the probability of proper classification. The performance of the system is verified using hollow axle sample with artificial notches of different depths. The experimental results are presented and discussed. Keyw...

We present a case study of a difficult real-world pattern recognition problem: predicting hard drive failure using attributes monitored internally by individual drives. We compare the performance of support vector machines (SVMs), unsupervised clustering, and non-parametric statistical tests (rank-sum and reverse arrangements). Somewhat surprisingly, the rank-sum method outperformed the other m...

BACKGROUND AND PURPOSE One of the reasons for the failure of trials of neuroprotection in stroke may be the lack of white matter (WM) protection. However, whether patients entered into typical neuroprotection trials have WM involved in the ischemic process is unknown. We studied patients who were enrolled in neuroprotection trials at our center and used a neuroimaging coregistration approach to...

This paper presents a concept of voltage-vector in three-dimensional space vector modulation for four-leg active filter which are developed based on Euler angle rotation method, and its produces a skewed rod shape consisting of twelve-pairs of asymmetrical tetrahedron nonzero switching vector in which voltage-vector reference is determined by four-pairs of its tetrahedron. Voltage-vector refere...

We propose a method based on the support vector machine to assess a set of clinical parameters for MCG diagnoses. By using this method, we can conclude whether the parameters are suitable for classifying a specific disease, and we can extract the dominantly working parameters from the set. In this study, we test a well-known set of the field-map parameters for ischemia detection by using our me...

In this paper, an adaptive motion vector smoothing scheme based on weighted vector median filtering is proposed in order to eliminate the motion outliers more effectively for improving the quality of side information in frame-based distributed video coding. We use a simple motion vector outlier reliability measure for each block in a motion compensated interpolated frame and apply weighted vect...

|In this paper, a novel lter structure is introduced for multispectral image processing, the vector median-rational hybrid lter's (VMRHF's), which constitute an extension of the nonlinear rational type hybrid lters called medianrational hybrid lter's (MRHF's) recently introduced for 1-D and 2-D signal processing. The VMRHF is a two-stages lter, which exploits in an e ective way the features of ...
