To make RFID technology assist people in their daily lives, a new technology called “Mobile-RFID” (mRFID) is being considered. The mRFID technology incorporates RFID-reader functionality into portable handheld devices. In a public zone (e.g., street, shopping mall) we can use our mobile phone as an mRFID-reader to scan tagged merchandize and quickly download information about that merchandize. ...

In this paper, we develop an empirical model of consumer usage and price uncertainty under a threepart tariff plan. Using this model, we study the effects of the recently proposed “Bill Shock” regulation in the mobile phone industry, a proposal that would inform consumers when they use up the monthly allowance of their mobile phone price plan. Using a rich billing dataset, we estimate an indust...

Mobile peer-to-peer (MP2P) networks refer to the peer-to-peer overlay networks superimposing above the mobile ad-hoc networks. Heterogeneity of capacity and mobility of the peers as well as inherent limitation of resources along with the wireless networks characteristics are challenges on MP2P networks. In some MP2P networks, in order to improve network performances, special peers, are called s...

Towards robust and convenient indoor shopping mall navigation, we propose a novel learning-based scheme to utilize the high-level visual information from the storefront images captured by personal devices of users. Specifically, we decompose the visual navigation problem into localization and map generation respectively. Given a storefront input image, a novel feature fusion scheme (denoted as ...

Background: One of the ways for effective communication between learners and instructional multimedia content in mobile learning systems is taking advantage of characters or pedagogical agents. The present study aimed to investigate the effect of the levels of realism in mobile-based pedagogical agents on health e-learning. Methods: The s...

e-learning model is examined of three major dimensions. and each dimension has a range of indicators that is effective in optimization and modeling, in many optimization problems in the modeling, target function or constraints may change over time that as a result optimization of these problems can also be changed. if any of these undetermined events be considered in the optimization process, t...

Immigrants gaining economic security tend to reinforce—not relinquish—their ethnic identification [Halter M. Shopping for identity: the marketing of ethnicity. New York: Schoken Books, 2000. p. 256.]. Shopping is one avenue where people affirm themselves. Mall shopping has become an expression of personal values. In this research, the authors investigate shopping values [J. Consum. Res. 20 (199...
