For the products that provide not only intrinsic value from their functions but also stylish consumption experience, there often exist both Veblen and network effects. Some customers are more likely to purchase the product if fewer customers can afford it, while others might appreciate the existence of more peers. Focusing on these products, we study the market equilibrium under rational expectations...
With the rapid development of technology, more and more products tend to both meet customers' functional needs and provide stylish consumption experience at the same time. In this paper, we define these products as “fashion tech” products. In practice there exist two opposite consumption externalities associated with “fashion tech” products: some people are more likely to purchase the product if fewer...
The dynamic fluid level of oil well is essential for the submersible motor. The prediction of dynamic fluid level is a popular research direction. This paper describes an approach to short-termly determine the dynamic fluid level by using the algorithm which combines the state space reconstruction and black hole least squares support vector machine (BH-LSSVM) algorithm together. The chaotic time series...
Introduces the basic concept of data mining technology and the commonly used methods of it, and describes the function of data mining technology and its application in general industrial production. Respectively summarize the application status of the data mining technology to production operation process in oil field, around production operation control, production operation parameter prediction,...
As a novel semi-structured language, XML has become the de facto standard of data exchange over the Internet, due to that XML is characterized by self-described, scalable and convenient for exchange. In order to filter the XML publishing events, a novel filtering method is presented with the optimized rewriting method and then, the proposed algorithm is proved by the algorithm analysis.
Set the date range to filter the displayed results. You can set a starting date, ending date or both. You can enter the dates manually or choose them from the calendar.
