During the last decade communication technology has changed rapidly. Due to its decreasing costs and rising expansion, IP (Internet Protocol) technology has found its way to areas that have long been the domain of publicswitched telephone networks (PSTN). Voice over IP (VoIP) applications are widely used not only for phone calls or common Internet conferences, but also tend to be used for safet...

Increased processing power and connectivity enable an integration of mobile devices into enterprise applications. The de facto standard for an enterprise integration is Web Service technology. Notifying devices of business events requires establishing an inbound connection to the devices. While establishing connections from mobile devices to enterprise systems is straight forward, the inverse w...

The real-time ECG signal processing system based on mobile phones is very effective in identifying continuous ambulatory patients. It could monitor cardiovascular patients in their daily life and warns them in case of cardiac arrhythmia. An ECG signal of a patient is processed by a mobile phone with this proposed algorithm. An IIR low-pass filter is used to remove the noise and it has the 55 Hz...

Today VoiceXML is the standard scripting language for rendering web pages over the telephone. Developing costs of an interactive phone application have changed dramatically with the new markup language. VoiceXML builds on the basic concept and rules set by XML. Interactive applications contain synthesized speech, pre-recorded audio, grammars defining words that could be recognised, and DTMF key...

Voice-over-IP (VoIP) technology has come of age and is quickly gaining momentum on Broadband networks. VoIP packetizes phone calls through the same routes used by network and Internet traffic and is consequently prone to the same cyber threats that plague data networks today. These include denial-of-service attacks, worms, viruses, and hacker exploitation. In addition to these traditional netwo...

Voice over IP (VoIP) is the technology allowing voice traffic transmission as data packets over a private or a public IP network. VoIP allows significant benefits for customers and communication services providers. The main are cost savings, rich media service, phone and service portability and mobility, and the integration with other applications. Nevertheless, the deployment of the VoIP techn...

OBJECTIVE To determine the potential of opportunistic glycated haemoglobin (HbA1c) testing of pathology samples to detect previously unknown diabetes. DESIGN Pathology samples from participants collected for other reasons and suitable for HbA1c testing were utilised for opportunistic diabetes screening. HbA1c was measured with a Biorad Variant II turbo analyser and HbA1c levels of ≥6.5% (48 m...

IP telephony has long been one of the most widely used applications of the peer-to-peer paradigm. Hardware phones with built-in peer-to-peer stacks are used to enable IP telephony in closed networks at large company sites, while the wide adoption of smart phones provides the infrastructure for software applications enabling ubiquitous Internet-scale IP-telephony. Decentralized peer-to-peer syst...

Transport layer mobility management is proposed as an alternative to network layer methods like Mobile IP for realising seamless mobility in the Internet. Mobility management in the transport layer is purely accomplished by use of SCTP (Stream Control Transmission Protocol) and some of its currently proposed extensions. With Mobile SCTP seamless hand over even crossing physical, link and networ...
