This paper presents an optimal inventory policy under a given stochastic demand such as uniformly distributed demand, single-item, single period review inventory system. The optimal inventory control policy obtained in this paper is called four-point policy, that is, when inventory level of the entity is below an ordering point, the entity orders the stock level up to a fixed level (second point);...
Amplitude Modulation (AM) is a commonly used method in radio communication. Compared with analog AM, Digital AM (DAM) has the advantage of higher accuracy and better controllability. This article is dedicated to the analysis of the key issues in the implementation of DAM and its corresponding parameters based on the theories of amplitude modulation while carrying out simulations using Matlab, whereas...
Exploratory data analysis is a data analysis methods to analysis data and find the inherent law based on the actual distribution of data. This article explored the use of data analysis, aiming at a communication operator for a pseudo-family customer to identify customers to focus on customers and achieve targeted marketing.
Different noninvasive or minimally invasive therapeutic ablation procedures can produce tissue necrosis associated with local-stiffness increase. Although elastography has been proved as a potential evaluation tool for many kinds of ablation-induced lesions, the application of subtraction technique in elastography to enhance the visualization of the ablation lesions has rarely been reported. In this...
