Objective Evaluations of the Manner and Effect for Artificial Hail Suppression Operation in the Middle Region of Inner Mongolia

[ Objective] The research aimed to conduct objective evaluation on manner and effect of the artificial hail suppression operation in central Inner Mongolia. [ Method] Depending on analyses of the radar observation data, hail shooting data and artificial hail suppression operation data in the middle region of Inner Mongolia （ represented by Huhhot） from 1990 to 2007, and combining capability of the artificial hail suppression operation tool （＂ 37＂ anti-aircraft gun）, nucleation rate of the catalyst and suitable catalyst volume in hail cloud per unit volume, objective evaluation of the manner and effect for artificial hail suppression operation in the area was obtained. [ Result] It was exacter to distinguish shape and intensity of the hail cloud, but it was uncertain to distinguish height of the hail cloud, when selecting operation target cloud. Operation height was still lower, and perfect seeding height couldn＇t be attained. Operation occasion was controlled well, but there still were phenomena of the late operation. Shell amounts of the operation were few obviously, needing to increase shell amount or to improve nucleation rate of the catalyst. [ Conclsion] Syntheti- cally, manner of the artificial hail suppression operation in central Inner Mongolia was suitable, and total efficiency was about 85%.

Pilling Image Acquisition method for Complicated Texture Fabric

In order to solve the problem of complicated fabric texture interference on the pilling segmentation during the objective evaluation of fabric pilling, a new method of pilling image acquisition was proposed. Firstly, multi-direction lights were projected on the pilled fabric surface and its pilling images were captured, which mixed with invariant fabric background texture and pilling profile information modulated by the variant light projections. The captured fabric pilling images were analyzed by independent component analysis method. Using the spectrum feature analysis method, the independent components belonging to the complicated fabric background texture were separated and the pilling images are reconstructed with the left components. The experimental results showed that this method can effectively separate the pilling image from complicated fabric texture, which provides one possibility for colored fabric pilling objective evaluation.

A procedural study of building up a performance evaluation indicator system of intellectual property protection

The intellectual property protection, whether judicial or administrative, is evaluated through a performance evaluation indicator system. To building up such a system, we must follow certain working procedures which usually consist of four steps： to determine the performance objectives, to design the structure of indicator system, to specify the indicators and to set up the weight of indicators. Each step plays a different role in performance evaluation indicator system and has its own impact on the realization of performance evaluation objectives respectively. So the scientifically building up a performance evaluation indicator system is the key to determine whether the intellectual property is protected well or not.

Episodic Learning and Memory in Prodromal Huntington’s Disease: The Role of Multimodal Encoding and Selective Reminding

This study investigated episodic memory in prodromal HD. Three groups were compared (N = 70): mutation carriers with less than 12.5 years to disease onset (n = 16), mutation carriers with 12.5 or more years to disease onset (n = 16), and noncarriers (n = 38). Episodic memory was assessed using the Fuld Object Memory Evaluation, which included multimodal presentation and selective reminding, and the Claeson-Dahl Learning Test which included verbal repeated presentation and recall trials. Both carrier groups demonstrated deficient episodic memory compared to noncarriers. The results suggest deficient episodic memory in prodromal HD, and that inconsistent retrieval contributes to these deficits. Multimodal presentation attenuates the deficits.

Evaluating quality of motion for unsupervised video object segmentation

Current mainstream unsupervised video object segmentation(UVOS) approaches typically incorporate optical flow as motion information to locate the primary objects in coherent video frames. However, they fuse appearance and motion information without evaluating the quality of the optical flow. When poor-quality optical flow is used for the interaction with the appearance information, it introduces significant noise and leads to a decline in overall performance. To alleviate this issue, we first employ a quality evaluation module(QEM) to evaluate the optical flow. Then, we select high-quality optical flow as motion cues to fuse with the appearance information, which can prevent poor-quality optical flow from diverting the network's attention. Moreover, we design an appearance-guided fusion module(AGFM) to better integrate appearance and motion information. Extensive experiments on several widely utilized datasets, including DAVIS-16, FBMS-59, and You Tube-Objects, demonstrate that the proposed method outperforms existing methods.

Objective Image Fusion Quality Evaluation Using Structural Similarity

Objective evaluations of fused images are important in comparing the performance of different image fusion algorithms. This paper describes a structural similarity metric that does not use a reference image for image fusion evaluations. The metric is based on the universal image quality index and addresses not only the similarities between the input images and the fused image, but also the similarities among the input images. The evaluation process distinguishes between complementary information and redundant information using similarities among the input images. The metric uses the information classification to estimate how much structural similarity is preserved in the fused image. Tests demonstrate that the metric correlates well with subjective evaluations of the fused images.

Objective visual performance evaluation with visual evoked potential measurements based on an adaptive optics system

An objective visual performance evaluation with visual evoked potential （VEP） measurements was first inte- grated into an adaptive optics （AO） system. The optical and neural limits to vision can be bypassed through this system. Visual performance can be measured electrophysiologically with VEP, which reflects the objective func- tion from the retina to the primary visual cortex. The VEP ts without and with AO correction were preliminarily carried out using this system, demonstrating the great potential of this system in the objective visual performance evaluation. The new system will provide the necessary technique and equipment support for the further study of human visual function.

Objective evaluation of cleft palate speech based on analyzing plosive consonants

An objective method, using a multi-band analysis technique, was proposed for analyzing plosive consonants in cleft palate speech. At first, the speech signal is decomposed in frequency domain using an auditory filter-bank. Then, the sample-based features, namely cumulative energy and its increment speed, in each band were computed. Finally, using principle component analysis, these features were fused into one combined feature vector for assessment. Since the algorithm is based on perceptual properties of human auditory ear using non-uniform and multi-band analysis, the improvements of the consistence between the proposed approach and subjective evaluation are obtained.
