All sorts of Malwares severely threaten users in Internet. These malwares do share some common characteristics, despite malware and its variants may vary a lot from content signatures. The common characteristics they shared can be used to reveal the real intent of malware. In this paper, we study on the behavior characteristics of malwares in Internet, and based on which we present the method to extract...
Malware, such as Trojan Horse, Worms and Spy ware severely threatens Internet. We observed that although malware and its variants may vary a lot from content signatures, they share some behavior features at a higher level which are more precise in revealing the real intent of malware. This paper investigates the technique of malware behavior extraction, presents the formal Malware Behavior Feature...
This study selected aquatic vegetation in BaiYangDian Wetland Nature Reserve in Hebei Province. Measuring the spectral reflectance of typical aquatic vegetation included stonewort, reed, lotus and typha, involved high-resolution GeoEye-1(GE) remote sensing image, based on spectral reflectance of different species simulating bands of GE, calculated the simulated bands, educed better bands or band combinations...
In the scenario of a disaster in the downtown area, an evacuation plan should be considered to move anyone out of the disaster area as soon as possible. In the mean time, emergency rescue crews brought from the suburban or other areas also need to respond to the disaster as soon as possible. Both the inbound emergency vehicle response time and outbound evacuation time are critical to save lives. Evacuating...
The present financial tsunami has brought credit risk into a main focus. Dynamic credit scoring tools is highly demanded by commercial banks with products like credit cards. However, till now practitioners almost only employ statistical scoring models such as regressions. Thus the purpose of this paper is to provide for a new direction of attempts in modeling consumer credit risk and behavioral scoring...
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);...
A heterogeneous fuzzy Markov model is built for modeling and forecasting credit behavior dynamics of credit card users in this paper. This model brings together a fuzzy rule-based inference system and the Markov chain. The credit migration rate matrix of the fuzzy Markov chain is obtained by the inference system based on reasonable setting of rules for each consumer, and updated at each time interval,...
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...
