Network education has been developing rapidly, but there is always a problem that learners' motivation is not high. This paper is based on incentive theory and motivation theory, according to four stages of teaching process: stimulate, guide, maintain and evaluate, the corresponding incentive measures are put forward, the structure of the network teaching incentive measures is formed. Then, on the...
This paper proposes an adaptive image denosing method. Conventional non-local means(NLM) method is not able to adaptively choose filter parameter. According to the characteristic value of different image patch, we build a prediction function, which is used to choose a suitable NLM parameter for the image, thus realize the adaptive non-local means filtering. Experimental results illustrate that the...
Cardiomyopathies are a group of genetically heterogeneous myocardial diseases. In primary cardiomyopathies, hypertrophic cardiomyopathy (HCM) and dilated cardiomyopathy (DCM) are usually autosomal dominant inherited. Network modules are often used to analyze biological insights of some diseases. In this article, we firstly collected pathogenic proteins of HCM and DCM from the PubMed database using...
A green method for separating and enriching trace chlortetracycLine (CTC) in river by phase-separation floatation(PSF) spectro-photometry has been proposed, the principium was discussed. In this paper, the hydrophobic complex composed of Fe(III) and CTC was floated into organic phase under the optimal conditions: ultraviolet detector setting at 398 nm. Phase-separation reagent using 1.5 mol•L-1 sodium...
For the last-stage blades of super-critical steam turbine, the problem of water erosion is serious. Using the design parameters of the last stage static and moving blade of a SC 600MW steam turbine, two-dimensional and three-dimensional numerical simulation of the flow field are carried out in this paper. And the distributing situation of the mach number, pressure, liquid density, nucleation rate...
How to acquire proper prior distribution is a key problem in Bayesian analysis. Aiming at the over-reliance on expert's information currently in multiple information fusion, a new method based on the second maximum likelihood estimation theory to determine the weight of the prior distribution is proposed. According to the method, prior information is combined with field test data which is seen as...
Stress is a main prosodic feature; it becomes more and more important in speech recognition, speech synthesis and understanding, especially in the spontaneous speech. This paper is intended to analyze whether the semantic stress has effect on pitch and durational pattern of prosodic word in broadcast presenters' speech. The research results shows that the stresses will not make a fundamental difference...
The interrelation between prosody and syntax becomes more and more important in speech processing. This paper is intended to analyze the syntactic correlations of prosodic phrase in broadcasting news speech. The research results in the followings: Firstly, the C-PP, which there is a stable prosodic pattern of pitch contour within its rhythmic chunking, has a flexible syntactic structure and stable...
We present an approach to recognizing sentiment polarity in Chinese reviews based on topic sentiment sentences. Considering the features of Chinese reviews, we firstly identify the topic of a review using an n-gram matching approach. To extract candidate topic sentiment sentences, we compute the semantic similarity between a given sentence and the ascertained topic and meanwhile determine whether...
In this paper, ANSYS finite element analysis software is used to simulate the twisted state of turbine integral rotor's discs. For various stepped shaft structure, the formula of ??-stiffness influence coefficient is fit by changing the geometric parameters of the equal-thickness disc, then equivalent diameter of stiffness is obtained. For the cone-shaped disc, the equivalent diameter of stiffness...
This paper presents the finite element analysis (FEA)-based surgical planning for the distraction osteogenesis of the maxilla with severe midface hypoplasia induced by a cleft palate. Based on the three dimensional FEA model of the craniofacial bone complex built from 2-D CT images for a patient with cleft palate, the maxillary advancements corresponding to LeFort I, LeFort II and LeFort III distraction...
At present, more and more enterprises gradually realize that the employee is valuable wealth. It is important to improve employee's satisfaction for human resources investment and value-added human resources. Based on the satisfaction research of salesman in department and analysis, summarize some common problems in terms of counter sellers satisfaction at present. Put forward the corresponding solution...
In order to improve and convey the semantic information perfectly and vividly through synthesized speech, a special prosodic phrasing in broadcasting news programs, namely complex prosodic phrase (C-PP), is proposed in this study. Empirical results show that the C-PP, which there is the pitch declination trend within it, a stable syntactic structure and whole semantic chunk, has a very important role...
Compared with the written word, few experts pay more attention to the spoken word because of the difficulty of obtaining spoken corpora. In order to develop and improve the spoken words research, this paper proposes a novel method for automatic extraction spoken words in broadcasting language, and the result is impressive. From analysis of the result, we extracted 3009 spoken words by the model on...
In order to extract catchwords, new words and other kinds of words for language monitoring, this paper propose the temporal-spatial modeling, which seemed the sort of words as the representation of the different word's distribution in a uniform temporalspatial system. The steady and dynamic features of the different distribution are given. Therefore various kinds of words could be identified and extracted...
As regards life insurance product of unit linked types, considering all the insuredpsilas expectant unit linked type products. Then no matter what their theories return and insurerpsilas expectant solvency can gravely affect to design the premium and its frame, the corresponding works is done in this research. The ideology sense of individual equity principle is assimilated, and the decision objectives...
Nowadays various mobile platforms from PDA, smart phones to iPhones can deliver road warriors or trippers much mobile information. However, most mobile applications are lacking the "social intelligence" of real companionship. One reason is that community context and spatiotemporal context information are not well taken into consideration. In this paper we propose an ontology-based context...
