Now that the number of cellular phone subscribers is over 1.6 billion in the world and over 180 million in the United States, it is an appropriate time to consider Asia, the “new” wireless economy, with respect to mobile telephony. Several major cellular phone service providers chose Korea as a testing ground to assess the effects of third generation (3G) technology and deployment. Several Kore...

The cell phone is one of the potential Information Communication Technologies (ICTs) in agricultural development especially in developing countries like Bangladesh. Thus, this paper deals with the farmers’ communication with the agricultural extension agents using mobile phone. The study was conducted in Mymensingh District in Bangladesh. Data were collected from a sample of 110 farmers while b...

The place of information in addressing market access and participation limitation, which hinders farmer’s welfare and poverty reduction efforts in many developing countries, cannot be over-emphasized. This study therefore examined the use of mobile phone in the marketing of food crops among farming households in rural south east, Nigeria. A multi stage sampling procedures was used in the select...

Somatic crossing over in flies heterozygous for a dominant Minute mutant may result in two cells, homozygous for wild type and Minute, respectively. If both cells took part in development, a twin spot of two genotypes, different from the rest of the body, would result. Two-hundred wild type spots were found, none of which was accompanied by an adjacent twin spot homozygous for Minute. The absen...

To my parents iii ACKNOWLEDGEMENTS I would like to express my sincere gratitude to my advisor, Prof. Edward J. Coyle, for his invaluable advice and persistent support during my Ph.D. study. Without his guidance, I would not have been able to successfully complete my dissertation. Moreover, his guidance in both my research and life has pretty much reshaped my way of thinking and working in the p...

The growing popularity of portable and mobile computing and communication devices along with the introduction of wireline broadband networks is fueling demand for wireless broadband networks. Since ATM has been accepted as the standard for broadband integrated service networks we consider the problem of providing \ATM-like services" to mobile devices. In this paper, we discuss the fundamental i...

In this paper, the performance of the uplink of a WCDMA Radio over Fibre access network during Macrodiversity mode is investigated. We propose a novel Macrodiversity scheme in the uplink, based on Maximum Ratio Combining (MRC) of the received symbols by different BS receivers of a WCDMA mobile cellular system with RoF. Our simulation results demonstrate that, for a given service, the coverage e...

The Radio over Fiber (ROF) communication technology combines the technical blessings of each fiber communication and wireless Cellular communication to unravel the issues of information measure, flexibility and magnetic attraction interference. Future generation of cellular Communication system should be capable of serving prime quality and broadband services even in extremely dense urban area....

results the prevalence of excessive mobile phone use was 36.7% on the students. there was a significant relation between the prevalence of excessive mobile phone use and mental health status in general (p > 0.05), and also somatization (p < 0.05), anxiety and depression specifically (p < 0.05), but no significant relation was found between the excessive mobile phone use and social dysfunction (...

We live in a networked age. Always-on technology now links people together in a myriad of ways that was inconceivable just a few decades The social impact of these technologies – especially over the last twenty years or so – has been massive. Networking has changed the ways we communicate, how we write, how we stay in touch with friends, how we conduct our day to day affairs, and even how we at...
