A zero-forcing (ZF) receiver has a quite simple structure and relatively good performance at high SNR. This paper studies the performance of a Multiple-Input Multiple-Output (MIMO) ZF receiver over continuous flat fading channels in the presence of practical channel estimation errors. We derive the bit error rate (BER) of MPSK for the MIMO ZF receiver considering the practical effects of channel estimation...
Mobile commerce, has become a significant topic in IS research community and it is a key concept for many businesses, However, it has not fulfilled the expectations. This paper tackles the issue of mobile commerce in three different ways. First, it emphasizes the relative importance of customer relationship management and its relationship with mobile commerce. Second, it illustrates the ways to enhance...
Fuzzy entropy and similarity measure were used to measure the information of data as real value. In order to calculate the certainty or uncertainty fuzzy entropy and similarity measure are designed and proved. Obtained measures were applied to the calculating process and discussed. Extension of data quantification results to decision making and fuzzy game theory were also discussed.
With the progress and ubiquitous features of Internet technologies, searching for the requisite information through internet has become a popular solution for information exchange. In addition, getting the required information through web query is becoming the most effective way for users due to the promotion of remote sensing image retrieval and popularity of image provision. However, how to make...
This study reviews target features, facilities, and open source software applications in libraries; inclusive is paid to evaluation of Libraries Open Source Software (LOSS)-as known YABANA-in University of Isfahan (UI). In this study research method is a descriptive survey and the results are presented in two main sections. First section includes comments experts worked with UILOSS about its technical...
By adding the trading volume, this paper extends the three-factor model (Fama and French, 1993) to study cross-section returns based on the upstream and downstream markets. The aims are to overcome the negative influence of using pre-period returns to substitute expected returns, and test whether explanatory powers of the trading volume and book-at-market ratio result from the overreaction of the...
The primary purpose of this study is to develop a Loyalty-Based customer relationship management (LBCRM) model and to propose the 3 As quality indices for its measurement. Currently corporate response to multiple stakeholders has been a trend in business strategic literatures. However, most of the CRM researchers are still exploring factors internal to the organization. Therefore, present study employs...
Open source software (OSS) is quickly becoming a reality in the software industry. Despite the increased proportion of OSS usage in software business, the software industry is still struggling with how to cope with this emerging paradigm. The author analyzes the patterns of OSS adoption in software business. Also, the author discusses the organizational transition stages that are encountered when...
Knowledge-intensive and collaborative environment becomes more significant in the modern product development. To realize a true knowledge-based product design environment, however, the complexity of design constraint is still cumbersome issue to tackle. Typically, product design information comes from various sources and rapidly changes; design is evolutionary. Thus, a minimal set of rules is required...
Constraints, diversity and evolution characterize mobile data services. These factors provide persistent challenges to the development of mobile data services. Recent challenges from Apple AppStore and Google Android also provide a new cornerstone for the construction of mobile ecosystems. Mobile data services continue to change their business models to cope with technological and business model evolution...
In the production of PVC gloves, there are 15 procedures which bring many difficulties to process control and diagnosis. In order to solve the problem, multivariate quality control method based on Principal Component Analysis was proposed. This article discusses the application of Principal Component Analysis in multivariate quality control of plastic products after summarizing the theories and methods...
The phrase, 'convergence technology,' refers to the synergistic combination of conventional industry and IT (Information Technology) including advanced computing and communications. The growing recognition of the urgency to reduce risks and production costs is motivating the development of improvements in the traditional manufacturing industry using IT convergence. This paper describes the IT convergence...
Collaborative product development has become important business strategy. In this paper, a framework for autonomous collaborative product development, in which a set of intelligent agents handle major interact tasks based on ontology, is presented. By wrapping engineering applications using agents, the framework applies generalized knowledge repository to leverages relative resources, knowledge and...
As manufacturing process technology enter into nano-phase, integrate billions of transistors on a single chip has become a reality. By combining pre-designed and configurable SoCs as complementary and independent resources, a new concept of embedded HPC system named as PRSoC was proposed. HPC architectures, MPI parallel programming specification, IPC mechanism of multi-core / multiprocessor system,...
As digital publishing is becoming the next mainstream trend, the traditional publishing industry must undergo transformation to cultivate talents and accelerate the switch to digital publishing. This study explores what professional abilities that digital publishing industry employees must possess. In this study, a literature review was conducted to collect information on the current development of...
The end effects of Hilbert-Huang transform are produced in the Empirical Mode Decomposition(EMD) and the Hilbert transform for Intrinsic Mode Functions(IMF), which have a badly effect on Hilbert-Huang transform. In order to overcome this problem, the multi-objective allocation Genetic Algorithm (GA) to solve the kernel parameters selection of Least Squares Support Vector Machine (LSSVM)(GLHHT) is...
Mobile computing devices are increasingly making use of multiple network technologies to provide seamless connectivity across changing operational contexts. Reliable delivery of video to mobile devices is particularly challenging in these dynamic and multi-network environments. This paper provides a report on our experience in applying Partially Reliable Stream Control Transmission Protocol (PR-SCTP)...
This is the part of the research of Korean cultural contents design creator that can build Korean folk villages of Chosun Dynasty, 1392–1910. From the sixteen villages preserved by government, all stone fences were observed and measured for database of Korean stone fences. The data sets are useful reference for digital contents producers who make games and films with old period Korean environment...
Simple genetic algorithm has many defects, such as premature and slow speed of convergence. This paper researches the frame and performance of four combination algorithms based on dynamic self-adaptive genetic algorithm (DSGA-SVM, DSGA-Logistic, DSGA-C4.5, DSGA-BPNN). In order to classify the customers into two groups representing low and high credit risk, the proposed algorithms are tested using...
Double gate devices, especially FinFETs have emerged as a superior alternative to conventional bulk MOSFETs to continue scaling down to sub 32 nm regime. According to the specified scaling length, a FinFET structure is superior in controlling short-channel effects (SCEs). Independent control of front and back gate in double gate (DG) devices reduces the effective switching capacitance and, hence,...
