Oral squamous cell carcinomas (OSCC) is the most common head and neck cancer worldwide, with more than 300,000 new cases being diagnosed annually. Studies have shown that miRNAs are involved in the process of growth, differentiation, apoptosis, invasion and metastasis of OSCC tumor cells. How miRNAs work together to contribute to this process is still largely unknown. The goal of our study was to...
In this paper, a novel non-integer times frame rate up-conversion (NIFRUC) algorithm using reliable analysis of time-domain motion information is proposed. The proposed method can realize frame rate up-conversion (FRUC) of any fractional multiples based on double FRUC. In addition, in order to eliminate motion jerkiness and motion blurring, the proposed method makes full use of motion information...
To alleviate the adverse effect of the multipath fading, we need to estimate the required fading margin for the link budget analysis. Compared with the Monte Carlo simulations, the theoretical analysis can estimate the system performance more rapidly and precisely. This paper studies the outage performance for selection combining based on the generalized correlated Weibull distribution with arbitrary...
This paper proposes a novel method of fusing different matching cost for dense depth map recovery in a global optimization framework. Two simple classical cost functions, NCC and SAD, are combined to make a complementary costs fusion, which is robust against noises and weak radiometric difference. We address complicated difficulties as texture-less region and occlusion in a multi-view energy based...
Complexity cohesion and coupling have been recognized as prominent indicators for software quality. One characterization of software complexity is the existence of dependency relationship. Moreover, degree of dependency reflects the cohesion and coupling between software elements. Dependencies on design and implementation phase have been proven as important predictors for software bugs. We empirically...
Image mosaic is an important branch in the field of image processing. This paper designs and realizes an image mosaic technique based on the information of edge. The technology is suitable for engineering application. First of all, two images of the adjoining frames are processed by convolution operation, get the edge images. And then we cut edge image into pieces and compute their spatial frequency...
This paper presents a geo-statistical method to study the spatial relationship between landslides and their inner-factors on the regional scale in order to predict the regional susceptibility of landslides. The approach is based on digital databases, along with such methods as statistics, spatial analysis based on Geographic Information System, and interactive mapping. The prediction map of study...
Filtering is an essential step to image processing, at present, a lot of filtering algorithm will damage the detail information of an image when they were used to remove noise that distribute over the image, in such circumstances, attaining an ideal effect is very difficult. The improved filtering algorithm based on gray correlation degree makes use of gray correlation analysis to find out random...
Requirements evolution is one of critical problems influencing software engineering activities. Despite there is much research on requirements evolution, there still lacks quantitative understanding of requirements evolution. In this paper, we quantitatively analyze requirements evolution across multiple versions of an industrial software product. Based on data of requirements evolution and defects,...
The kinetics and thermodynamics characteristics of Pb(II) and Cu(II) adsorption onto fly ash of a oil shale-fired power plant was investigated by using batch adsorption method. The results showed that Langmuir and Freundlich adsorption isotherms were applicable to the adsorption process, while Freundlich equation is more applicable. The mechanistic steps of the adsorption process was studied through...
The kinetics and thermodynamics characteristics of Cd(II) and Zn(II) adsorption onto fly ash of a oil shale-fired power plant was investigated by using batch adsorption method. The results showed that Langmuir and Freundlich adsorption isotherms were applicable to the adsorption process, while Freundlich equation is more applicable. The mechanistic steps of the adsorption process was studied through...
This paper presents a novel depth recovery technique of bifocus imaging system which may produce two focus images by independent focal lengths. Depth information can be extracted from the disparity between two focus images. This paper will propose the depth recovery formula and related algorithms such as feature extraction, sub-pixel matching, and center estimation. Experiments on real scene images...
K-means is a widely-used clustering algorithm in data mining. In traditional algorithm, each feature is treated equally and each one gives the same contribution to K-means. In fact, redundant and irrelevant features may disturb the clustering result. This paper proposes a improved K-means algorithm based on a fuzzy feature selection strategy. The method is based on measuring 'feature important factor'...
Distribution of effort in software engineering process has been the basis for facilitating more reasonable software project planning. This paper reports empirical results on activity effort distribution patterns of a series of industrial software maintenance projects. The results show that with respect to different influencing factors, the projects demonstrate large variations in their activity effort...
