A hierarchical model is presented for the implementation of a qualitative assessment of the system's operability. The system consists of objects. Objects are characterized by their parameters. The estimation is based on the determination of the state of the parameters. The procedure is carried out by introducing intermediate scales of numerical estimation. Qualitative assessments are aligned with...
Currently, ground-based cloud images taken by using a whole-sky imager are especially popular in the field of meteorology because of their high resolution and accurate cloud information. Cloud images are natural texture images, and thus texture features based on local binary patterns (LBPs) are widely used to analyze texture images. However, the high-computation cost of extracting LBP features from...
Parametric statistical tests (e.g., t-tests) can sometimes return highly significant results in cases that would be considered uninformative, such as when the individuals’ accuracies are just above chance. This paper demonstrates that permutation tests can produce the expected non-significant results in these datasets. The properties of null distributions underlying this difference in significance...
OBJECTIVE: To measure the kinetic parameters of pushing manipulation with one-finger, and provide quantitative evidence for the evaluation of PMOF manipulation. METHOD: The trajectory images and the manipulative force of the point-pressing manipulation were tested and recorded by a multi-film pressure measurement system. RESULTS: The average maximum force of PMOF was maintained at 11.75±0.88N substantially,...
In this paper a sign-based or semiotic formalism is considered. Neurophysiological and psychological researches indicate sign-based structures, which are the basic elements of the world model of a human subject. These elements are formed during his/her activity and communication. In this formalism it was possible to formulate and solve the problem of goal-setting, i.e. generating the goal of behavior.
Smart distribution grid(SDG)is the focus of the future smart grid construction, it will have a profound impact on the operation of power system protection and control. In this paper, the concept and characteristics of SDG are systematically introduced, then brief introduce SDG background, significance, as well as overseas and domestic research status. The key technologies of SDG are discussed, including...
Teaching management, central in education and teaching, has a significant influence on the implementation of education work and the improvement of teaching level. This article takes the teaching management of universities as its study object, and briefly analyzes the problems regarding IT application in the teaching management of universities and corresponding solutions. It first briefs the meaning...
Permutation tests are widely used for significance testing in fMRI MVPA (multivariate pattern analysis) studies, but the precise way in which the tests are carried out varies, and test design is non-trivial because of complex, auto correlated, and stratified dataset structures. Previously, we described permutation tests for single-subject datasets, recommending adoption of "dataset-wise"...
Aiming at neural network structure designing problems, a new hybrid pruning algorithm was put forward. The algorithm consists of three steps. Firstly, it uses cooperative co-evolutionary genetic algorithm (CCGA) and back propagation algorithm (BP) to optimize the number of neural nodes and the weight values; Secondly, it calculates the significance of the hidden layer neurons; Thirdly, in order to...
An Automated Recognition Technique for Lung Vessel Tree (ARTLVT) was proposed. ARTLVT was a one of 3-dimensional processing techniques, and had a recognition engine named Successive Region Growing (SRG). ARTLVT automatically found a cross-section of trachea from multi-slice CT images of hundreds. ARTLVT applied SRG to the cross-section and extracted trachea, bronchi and both lung fields. Based on...
Permutation tests are widely used for significance testing in classification-based fMRI analyses, but the precise manner of relabeling varies, and is generally non-trivial for MVPA because of the complex data structure. Here, we describe two common means of carrying out permutation tests. In the first, which we call the "dataset-wise" scheme, the examples are relabeled prior to conducting...
By integrating different radio technologies, the heterogeneous wireless network is excepted to support end-to-end QoS and provide the “best” user experience. However these integrated networks have different access technologies and complex designed parameters. Current researches on the uncertain relationship among those parameters in such a dynamic and complicated system made it difficult to optimize...
Practical teaching is the key to the development of vocational education, is the “core” and “breakthrough” of higher vocational education personnel training mode reform. And the construction of practical training base is the premise and guarantee of training education, China's higher vocational education training base construction after years of groping, what problems still exist, what new problems...
To begin with the origin of low-carbon economy, the thesis, aiming at promote sustainable development of Chinese economy, makes an analysis on the strategic significance and realized access and puts forward the possible means to achieve this. By employing documentary method, the thesis analysis the essential differences between Chinese low-carbon economy development and that of western developed countries...
Mining web traffic data has been addressed in literature mostly using sequential pattern mining techniques. Recently, a more powerful pattern called partial order was introduced, with the hope of providing a more compact result set. A further approach towards this goal, valid for both sequential patterns and partial orders, consists in building a statistical significance test for frequent patterns...
Faced with a deluge of data, an analyst must ask ``what data records are important?'' This paper answers that question by first defining a continuous spectrum of data record significance: ``known'', ``anomalous'', ``interesting'', ``novel'', and ``noise''. The definition has a geometric interpretation in that the significance of a data record in a predictor system is inversely proportional to it's...
Liaoning province, as the earliest industrial base in China, has been the major heavy industry center since the founding of the country and thus its economic development highly relies on energy utilization. Now confronted with the approaching exhausting of primary energy, the economic development of Liaoning province faces its bottleneck. With statistical analysis, this paper selected the panel data...
Augmented Reality (AR) is a branch of Virtual Reality (VR). With the development of this novel technology, the applications of the AR based education are attracting more and more attention. This paper points out the significance of AR-based experiment in education and illustrates the applications and effectiveness of AR-based experiment. We hope this can become a hint for the educators and researcher...
Today, computer is spreading from cities to villages. The building of socialism new villages is very important to modernization of China. Especially the financial management in country relates with the modernization of village. Because of this, using computers in rural financial management is necessary. However, the status quo of using computers in villages is not satisfactory. We will set some examples...
The colleges and universities should focus on improving their innovative ability of science and technology to be successfully transferred into a research university. This paper made a discussion on what the establishment of colleges and universities scientific and research team means to a research university, and pointed out the characteristics of the team and the focal point of work when establishing...
