With the rapid development of big data analytics in online marketing, real-time bidding (RTB) has emerged as a promising business model in recent years, and now becomes one of the major online advertising channels. Based on analysis of Web Cookies, RTB platforms are able to precisely identify the features and preferences of target audiences visiting publishers' websites, and forward the generated...
Correlated double sampling(CDS) operation is generally used in CMOS imaging systems, implemented by switched capacitor(SC) circuits, to get rid of reset noise and decrease flicker noise. This paper presents an optimization method for the noise performance of a CDS circuit, the advantage of which is its ability of canceling the offset of the OP involved. The structure of the CDS circuit is analyzed...
As the important factors affecting the economic growth, system innovation and technological innovation have been widely attended. But there is little quantitative research on them. According to the theory of grey correlation analysis, this paper calculates the contribution degree to the economic growth through 10 indexes which can measure the system and technological innovation from 2005 to 2014....
Cyber-Physical Systems (CPSs) as advanced embedded systems integrating computation with physical process are increasingly penetrating into our life. Modeling and analysis for such systems closely involved with us are actively researched. A current challenging problem is how to take advantages of existing technologies like SysML/MARTE, Modelica and Statistical Model Checking (SMC) through effective...
Although many theoretical methods were developed to price various derivatives, pricing deviation still remains very high. This paper provides a pragmatical option pricing method by combining skew ness and kurtosis adjusted Black-Scholes model of Corrado and Su, time series analysis and Artificial Neural Network (ANN). The empirical tests in FTSE 100 Index options show that pricing deviation calculated...
Business models are widely referred as the ‘logic of the firm’ —how it operates and creates value for its stakeholders. The paper, based on the CR Framework of business models, identifies the components of business models and models the value creation relationship among them by demonstrating business models of two world famous cosmetics companies. The results of the empirical analysis exhibit fully...
Vitamin C has value in treatment or prevention of scurvy and it can be obtained from vegetable and fruit. Vitamin C is usually determined by traditional chemical methods which are destructive, time-consuming. This paper was conducted to study the vitamin C (VC) content estimation in chilies using quantitative analysis technique based on visible/near infrared (Vis/NIR) diffuse reflectance spectroscopy...
Fast-flux based service network is first introduced as a technique used to improve the reliability and quality of a service system. But recently, this technique is also adopted by cyber-criminals and Internet miscreants to evade identification and to frustrate law enforcement and anticrime efforts aimed at locating and shutting down the illegal service. Previous work on this topic focuses mostly on...
Enterprise training is a very useful method to improve comprehensive quality of staff and to enhance the enterprise's core competitiveness, so the effect of training is the emphasis for an enterprise. In the paper, the multilevel comprehensive gray evaluation model is proposed to analyze training effect quantitatively in enterprises. Through case analyses, a reliable quantitative conclusion be get...
