Perspectives The Global Polio Eradication Initiative, established in 1988, has led to the immunization of 2.5 billion children against the disease. In 2014, only 359 cases of poliomyelitis (polio) were reported worldwide, which is a fraction of the estimated 350 000 children in 125 countries who were paralyzed annually by the poliovirus before 1988. There are only two remaining countries where ...

In this paper we analyze a large-scale comprehensive dataset from a major European Mobile Phone Provider (EURMO). This dataset allows us to study the diffusion of the iPhone 3G. We provide evidence of contagious adoption. We show that the propensity for iPhone 3G adoption increases with the number of individuals within the social network that have previously purchase the iPhone. We bound the im...

New and increasingly advanced data services are driving up wireless traffic, which is being further boosted by growth in voice applications in advanced market segments as the migration from fixed to mobile voice continues. Meanwhile, difficult market conditions have caused a number of operators to delay making substantial investments in upgrading their networks to higher capacity technology. In...

With exponential growth of mobile subscribers , mobile data traffic has been projected to experience, with increasing demand for the bandwidth. To support the rate of growth there will be need for the device & standard capable of providing next generation mobile network that require high data rate to obtain video streaming, live gaming, voice over Wi-Fi ,database search, file transfer & other f...

Wireless location has received considerable attention over the past few years. Many techniques, such as time-based methods (TOA and TDOA), AOA based methods, and Assisted-GPS, have been proposed. Time-based methods such as TOA and TDOA, are particularly exciting since they are sufficiently accurate for E911 under ideal conditions. However, several error sources, such as NLOS (Non-Line-Of-Sight)...

In next-generation wireless systems, one of the major features that is different from the current personal communication service systems is the seamless global roaming. The mobile subscribers will be allowed to move freely across different networks while maintaining their quality of service for a variety of applications. To meet this demand, the signaling protocol of mobility management must be...

The ability to analyze and reproduce specific-person facial expression is an important multimedia content service for mobile communication. In this paper, a novel three-layer facial animation model is presented for generating the personalized facial sketch animation, and the three layers are motion sequence layer, the reference shape layer, and the painting shape layer. Based on the model, a fa...

INTRODUCTION Online social networking services such as Facebook (www.facebook.com) have continued to increase in popularity , likely due to the accessibility of mobile internet on smart phones and tablets. Between 2010 and 2011 alone, the number of mobile Internet subscribers increased by 45% (7). Among consumers aged 16 and over in the UK and US, it is estimated that 95% own mobile devices (8)...

IP Multimedia Subsystem (IMS) has resulted from the work of the Third Generation Partnership Project (3GPP) toward specifying an all-IP communication service infrastructure (24.229 2009). Mainly looking at the needs and requirements of mobile operators, the 3GPP first specified IMS as a service architecture combining the Internet’s IP technology and wireless and mobility services of current mob...

Let us know how access to this document benefits you. The number of wireless mobile communication service subscribers has reached 4.6 billion worldwide in 2009, and mobile revenues are expected to be over $1 trillion around 2012 number of studies have been done to forecast the growing market and evaluate the new generation technology, the Beyond 3 Generation (B3G). However, there is no study fo...
