There are many problems in the current massive open courses (MOOC) platform construction, such as high cost, high energy consumption, long construction period and poor reusability. In order to solve the above problems, a new platform construction schema of MOOC+Small Private Online Course (SPOC) based on Internet Data Center(IDC) is proposed. This platform can help users to quickly create their own...
Bioelectrical impedance is a body's important parameter, which, to a certain degree, reflects the physiological state of the human body. According to the shortage that traditional five-segments model of human body impedance can't satisfy the needs of figuring out human trunk subdivision impedance, the exiting solution of eight-segments bioelectrical impedance module is premised on the basis of symmetrical...
The prediction model of existing human body composition based on measured bioelectricity has problems that include redundant influence factors and low prediction accuracy. To address these problems, this paper put forward a human body composition prediction model based on Akaike Information Criterion (AIC) and improved entropy method. First, combining with the AIC information principle, we selected...
Generally, well-constructed gene regulatory models can serve as a blueprint for researchers to understand the complex regulatory relationships among genes. Since the traditional models and methods for network construction are with low accuracy, and do not reveal detailed mechanisms among in-cell substances related to gene regulation, we present here a new dynamic model of gene regulation with reference...
Body composition analysis can not only reflect the state of health, but also can play a role in disease prevention. Aiming at many influencing factors, complex modeling issues of the existing bioelectrical impedance analysis algorithms, this paper draws information entropy theory into modeling the human body composition for the first time, establishes entropy evaluation criteria of physiological characteristic...
This paper used mixed logit model to predict credit risk of listed companies in China. In order to reduce the difficulty in dealing with the facts of correlation and multidimension of the financial indexes of listed companies and meanwhile to ensure that the data are not lost, we introduced factor analysis to the mixed logit equation and constructed a factor analysis mixed logit model. Fifteen factors...
To verify whether a compositional Web service is compliant to the specific requirements of users is one of important research issue for Web service. Most of existed work about Web service verification do not address the issue of how to model the requirements that the BPEL4WS processes are supposed to satisfy. The specifications are temporal relation based on actions or messages in essence. Distinguish...
As the change of power energy structure, the electricity markets are shifting gradually from sellers markets to buyers ones. Demand side management, which is one of the most important methods for energy management, plays an important role in power operation. However, the implement of DSM is a complicated market process which should keep the market effective and fair. From the views of economics, it...
In order to analyze the innovation capability in the complex multiple-attribute environment, a novel approach, used to evaluate the innovation capability of home appliance manufacturers, is presented. Furthermore, based on the assumption of a relationship between specific resources managed by manufacturers and their innovation capability, the authors suggested a reasonable evaluation indicator system,...
This paper considers practical stability of stochastic swarm systems. Taking a simple function of mutual attraction and repulsion between the individuals, a stochastic swarm model with and without perturbations is defined. The practical stability of the system is proved. Then, stochastic swarm models with some kinds of perturbations and their corresponding practical stability are discussed. Finally,...
Customer choice behavior, to a certain extent, determines the different mode types of Internet service provided by Internet Service Provider (ISP). But this aspect is often neglected by a majority of researchers. This paper introduced a simple customer choice model in which the probability of customer choosing a type of services was the function of service subset provided by ISP and therefore, the...
