Limb ischemia reperfusion (LIRI) injury is associated with serious local and systemic effects. Reperfusion may augment tissue injury in excess of that produced by ischemia alone. Calcium overloading and inflammation are considered to be two of the pathological mechanisms of limb ischemia/reperfusion (I/R) injury. Tao‐Hong‐Si‐Wu decoction (THSWD) is a traditional Chinese herbal medicine with a powerful...
According to the tire inflation pressure changes leading to tire vertical stiffness variation, formulas including tire inflation pressure, load, rolling radius and tire footprint width are deduced. And determine wheel speed sensor numerical value as the critical parameter of predicting tire pressure change. The tire pressure monitoring test is designed and carried out, and the correctness of the algorithm...
A scale parameter of a Gaussian kernel relevance vector machine (RVM) directly determine a result of the RVM regression. Because this scale parameter interval is from zero to positive infinite, it is difficult to choose the proper scale parameter for the Gaussian kernel function. This paper introduces a differential approximation method (DAM) to determine a scale parameter interval for a Gaussian...
A segmentation method comprising gray projection, discrete wavelet transform and adaptive segmentation was proposed to realize automatic failure recognition for trouble of moving freight car detection system (TFDS). The correlation between distribution of gray scales and their location were considered when segmented the objects. Calculate the vertical gray projection. Fit the centerline accordingly...
In order to calibrate camera-with-filter in structured light system, we propose a calibration method using projected features and construct an assistant camera based model. According to the filter being used, we can project feature points with corresponding wave length to the target which can pass through the filter. The camera-with-filter as well as assistant camera is used to photograph the target...
For non-single viewpoint catadioptric omnidirectional camera composed of a smooth rotational surface and a common camera, a simple model is provided by using a moving point on the optical axis and a space vector to represent the nonlinear mapping between pixels and space points and relationship of motion and rotation. A flexible calibration procedure which uses Taylor approximation is provided. This...
This paper developed a framework to analyze the performance gain in multiple-input multiple-output (MIMO) systems together with cognitive radio (CR) interference communication systems based on average channel state information (CSI). Because of interference between the cognitive user and the licensed user, the cognitive user must optimize its power to ensure the licensed user's transmission stability...
Fingerprint based personal identification is becoming more and more popular in everyday life. Designing an accurate real time automatic fingerprint identification system is of great importance in many circumstances, and this question has attracted lot of scholar's attention. In this paper we present a new real time fingerprint recognition system based on a novel fingerprint minutiae matching algorithm...
The performance of an automatic fingerprint identification system is essentially determined by its fingerprint matching algorithm. In this paper, a novel improved fingerprint image matching algorithm based on vector matching method with variable weight modification is proposed. That is features are extracted from fingerprint image as "vector points" and an improved vector matching method...
