Authentication and roaming are two critical issues for the integration of heterogeneous networks, such as the integration of WLAN access networks and mobile cellular networks. Due to the strong points of mobile cellular networks, it is favorable to integrate the authentication mechanism ofWLAN access networks into that of mobile cellular networks. For GSM/GPRS networks, the subscriber identity ...

Normally, the multimedia content provider and network service providers are separated in mobile TV systems. The TV programs are broadcasted from the content provider to the mobile terminals through Digital Video Broadcasting Transmission System for Handheld Terminals (DVB-H), and the access information is unicasted from the service provider to the user via General Packet Radio Services (GPRS) n...

BACKGROUND Termination of pregnancy (ToP) is currently illegal in Ireland. In 2010, more than 4000 women travelled from Ireland to the UK for a ToP. OBJECTIVES The aims of this study were to assess the attitudes and clinical experiences of Irish General Practitioners (GPs) and GPs-in-training (GPRs) towards ToP. METHODS A postal survey was sent to 500 GPs in Ireland. An internet-based surve...

This paper proposes and implements a low cost object tracking system using GPS and GPRS. The system allows a user to view the present and the past positions recorded of a target object on Google Map through the internet. The system reads the current position of the object using GPS, the data is sent via GPRS service from the GSM network towards a web server using the POST method of the HTTP pro...

Objective Dilated cardiomyopathy (DCM) can cause structural and functional changes in the left ventricle (LV). In this study, we evaluated whether cardiac magnetic resonance tissue-tracking (MR-TT) can be applied to the detection of LV abnormalities in patients with DCM. Methods We used MR-TT to analyze the global peak radial strain (GPRS), global peak circumferential strain (GPCS), and global ...

We present the results of a series of experiments used to characterise the performance of a GPRS (General Packet Radio Service) wireless data network, hence highlighting issues that software architects should consider when designing applications to run over this soon to be widely-deployed service. In summary, we show that packet Round Trip Time (RTTs) are large ( 1000ms) and can be highly varia...

In this work a new type of device is introduced: a bi-processor SmartPhone equipped with a network interface GSM/GPRS/EDGE/UMTS. The architecture used, with two processors, is introduced to take advantage of the subdivision of the functionalities provided by the two processors. A better distribution of various functions is achieved, all above when multi-media traffic is considered. Moreover, th...

With a shortage of GPs in England, there is a need to consider the career development for new GPs to ensure that they remain in post. This study examines, by means of a postal questionnaire survey, the views of GP registrars (GPRs) about their future careers in Yorkshire, England. The response rate was 59%. One hundred and eighteen (60%) responders were female, of whom 80 (39%) were planning to...

Reducing electricity consumption and integrating renewable power generation sources represent two of the main drivers of the so-called Smart Grid. Machine-to-Machine (M2M) communications will play a key role on making such a Smart Grid a reality, since they will enable the required bidirectional real-time bulk information exchange. However, communications for the Smart Grid present specific req...

Today’s fast growing world needs fast communication, either it may be voice or data .This calls for a new technology which is faster than all existing technologies in mobile communication and hence can replace technologies like GPRS .Enhanced Data for Global Evolution (EDGE) is such a technology .EDGE is a member of global system for mobile communications(GSM). In short EDGE is a technology whi...
