Aiming at the shortages of the existing data-mining model for classification of customer's credit sale risk, a new classification model based on rough sets and support vector machine presents is put forward in this paper. First, the theory of rough set is applied to pick up and reduce the index attributes. Then, the training samples are sent to the support vector machine to train and learn. After...
Disasters, both natural and manmade, of colossal proportions have continued to beleaguer Pakistan especially over the last 3 decades. Response of the government agencies and that of the general community has improved with time but still can be best described as “reactive”. In the aftermath of the devastating 2005 earthquake corporate sector played its role as a key partner in disaster management....
In this paper a modified Offset Min-Sum decoding algorithm for Low-Density Parity Check Codes is presented. In this modified algorithm, the offset factor in the original Offset Min-Sum algorithm is adjusted iteratively with the assistance of the check-node computation outputs of the Normalized Min-Sum algorithm. As a result, the offset factor in our modified algorithm can be calculated adaptively...
Grid computing is increasingly being viewed as the next phase of distributed computing. Built on pervasive Internet standards, grid computing enables organizations to share computing and information resources across department and organizational boundaries in a secure, highly efficient manner. Grid computing originates in e-Science and its early development was driven to a large extent by the requirements...
This paper pairs of comprehensive survey of government Web sites of Handan, sums up the existing major problems, generates the analysis of reasons, puts forward ways and measures to improve it: step up publicity; strengthening the service capacity; establish and improve related security system; emphasis on the government Web sites performance evaluation; encourage the public to participate in government...
The prevalence of chronic diseases is increasing at an alarming rate. Among them the incidence of Type-2 Diabetes is rapidly increasing globally. Although genetics could play an important role in the higher prevalence of this disease, it is not clear how genetic factors interact with environmental and dietary factors to increase their incidence. In the current study, Gene Expression Analysis was performed...
This paper initiates a novel simple mathematical model for exploring the mysterious dynamical mechanism of synchronized clapping. Based on this model, we set up an experimental platform of emergent computation for simulating many hands clapping. We find that there exists a critical region from the disorder applause to the emerging rhythmic clapping. Moreover, the clapping intervals obviously slacken...
In order to solve the problem of BP neural network, genetic support vector regression is presented to predict the lifetime of cylinder. Support vector regression (SVR) is a novel prediction algorithm based on structure risk minimization principles, which can lead to great generalization ability. In the genetic support vector regression model, the genetic algorithm is used to optimize the parameters...
This paper summarizes the internationalization characteristics of EIFs (early internationalizing firms) and discusses their internationalization drivers based on a literature survey. We propose an analytical framework for the internationalization of EIFs which embraces factors of entrepreneurs, firms and their external environments as antecedents and internationalization behaviors as intermediate...
This paper provides a solution for ERP software selection & elimination. ERP is a way to integrate data and processes of an organization into a centralized system that aims to have a single software solution where the information needed for decision making is shared across different departments. The selection or elimination of technology is a multi-criteria, multi-attribute, decision making problem,...
The modeling and simulation of lightning discharge are very important for the lightning protection engineering and lightning research. In this paper, with the thundercloud electrostatic model and potential equation in the space, a three-dimensional(3-D) numerical simulation of lightning discharge at 50-m resolution was presented. The dielectric breakdown model(DBM) based on fractal theory and bidirectional...
With the emergence of e-books, especially the invention of e-book reader, e-books has formed one industry; people's reading custom is changing quietly. This article mainly aims at four series of e-book reader, best-selling both domestic and international today, to do a comparative study. That is Amazon Kindle series, Sony PRS series, Hanwang “electronic paper book” and WeFound of Founder Group. The...
The development of future more electric aircraft systems is a challenging process: The respective subsystems are highly integrated to achieve an optimum efficiency and performance both at aircraft and at systems level. For master this multi-disciplinary challenge, the use of powerful modeling and simulation technologies such as Modelica in all phases of the system development process is a key success...
This study proposes to analyze morphological characteristics of electroencephalogram (EEG) signals in order to define a representation of epileptiform events that can distinguish them from other events occurring in the signal. Despite the existence of several studies on parameterization of EEG signals, particularly for automatic detection of paroxysms related to epilepsy, it was necessary to create...
Increasing IP based infrastructure of wideband and networks from one side and furthermore, the competitive atmosphere of business in terms of covering the consumers' expectation with raising the quality of their services, are leading to make IPTV pervasive. Consumer behavior on the web has been the subject of considerable research in the last few years, but understanding it is made difficult by the...
Online shopping is the process whereby consumers directly buy goods, services etc from a seller interactively in real-time without an intermediary service over the Internet. Nowadays, online shopping has become increasingly popular. However, affected by many factors, the purchase activities of consumers in online shopping is different from that of consumers in traditional shopping. This essay involves...
The aim of our research is to find a suitable RE process to be applied in our organisation for the development of software projects. We identified the actor and their roles through the relation practice while implementing the RE process. In order to redefine the RE process, good analysis skill is needed besides having a good understanding of the RE process itself. We believe that our experience can...
Service innovation is fundamental competitiveness to service enterprise. Researches on domestic service enterprise shows that organization support and emotional labor, Psychological empowerment, learning commitment, internal social capital are the key variables to significantly affect employee's service orientation and further service innovation. So managers should strengthen organization support,...
The Quadrature Mirror Filter (QMF) basically is a parallel combination of of a High Pass Filter (HPF) and Low Pass Filter (LPF), which performs the action of frequency subdivision by splitting the signal spectrum into two spectra. Thus QMF finds wide applications in many signal processing tasks such as transmultiplexing, equalizing wireless communication channels; sub-band coding of speech and image...
Sparse signal approximations have become a new tool in signal processing with wide ranging applications from source separation to signal acquisition. Recently, many algorithms for sparse signal reconstruction have been developed, however, greedy algorithms, such as Orthogonal Matching Pursuit algorithm, can have better performance than the other algorithms. Approximate orthogonal matching pursuit...
