In the submarine oil pipeline inspection, the magnetic flux leakage data may exist some abnormal values. In order to obtain the true value, the magnetic flux leakage data should be preprocessed. One of the important parts of data preprocessing is to discriminate the abnormal values, and predict and compensate its true value reasonably and effectively. In this paper, it combines threshold segmentation...
Automatic Target Recognition (ATR) technology is of great significance in security inspection, while traditional object detection methods are proved not efficient in human body millimeter-wave images. In this paper, we propose a synthetic objection detection method for millimeter-wave images. We choose saliency, SIFT and HOG features to form image descriptors. According to sparse representation, the...
Nutrient allocation and usage plays an important part in regulating the onset and progression of age‐related functional declines. Here, we describe a heterozygous mutation in Drosophila (dFatp) that alters nutrient distribution and multiple aspects of physiology. dFatp mutants have increased lifespan and stress resistance, altered feeding behavior and fat storage, and increased mobility. Concurrently,...
Through summing up the research of other scholars, the definition of multilevel teaching was given. As an example, the implementation and outcomes of computer fundamental course of Business College of Beijing Union University was deeply studied. This paper introduces the background, the scheme, and the specific process for classified teaching. Different objectives were determined, different teaching...
The performance of automatic fingerprint identification system relies heavily on the quality of the captured fingerprint images. A novel method for fingerprint image quality analysis has been presented, which overcomes the shortcoming most of existing methods have, considering the correlation of each quality feature as linear and paying no attention to the clarity of local texture. In this paper,...
Aerial in-situ test is an important constituent of modern aerial maintenance and repairing technology, which can detect the performance of aircraft structure quickly. Aiming at the low efficiency of the present in-situ test methods, the paper proposed a novel method named PSO-SVM which combined the improved particle swarm optimization (PSO) with support vector machine (SVM). The method could classify...
