In recent years, the demands for LED are increasing. For testing the quality of LEDs, a lot of LED probes are necessary, so the high precision and efficient methods are paid more attention by industrial applications. This paper is focused on the measurement of the angle and the radius of a LED probe by computer vision. In previous paper, we proposed an effective method based on Canny edge detection...
MicroRNAs (MiRNA) are small non-coding RNAs that regulate gene expression. Up to date, seventy miRNAs have been found differentially expressed in lung whole tissue between smoking patients affected by Chronic Obstructive Pulmonary Disease (COPD) and smokers. The aim of this study was to explore the associated miRNAs with emphysema severity of COPD. Firstly, we identified miRNAs differentially expressed...
A novel high quality semiconductor cross indictor is presented. Practical modular setup and the measurement results verify the theoretical deduction and optical design simulation. We have achieved the fine and sharp cross lines to the excellent result of 1.4 mm and even the best result of 1.2 mm in line-width, both in red semiconductor light source and in green semiconductor light source. What is...
This paper proposes an approach of dual-filtering messages. First the combination of KNN classification algorithm and rough set separates spam messages from messages. To avoid lowering precision for reduction, it needs to use KNN classification algorithm to re-filter some messages. This method not only improves the speed of classification but also retains high accuracy based on rough set of KNN classification...
