A major trend in the computing industry is the move towards computers in portable products. This can be seen as the sales of laptops now surpass desktops, the emergence of a new class of devices known as Personal Digital Assistants (PDA’s), and the growth in the sale of consumer electronics devices such as pagers, cellular phones, viewmen. For a large number of these products, battery life is a...

In a few short years, we have witnessed a massive uptake in the use of cell phones, personal digital assistants and hybrid devices that integrate phone, computer and Internet services. These devices communicate with one another and with traditional computers. Along with the Internet, they have transformed our computational environments into communication spaces. The goal of our research is to s...

Java applications are becoming increasingly popular for embedded devices, like cellphones or personal digital assistants. The reasons for this success are the properties of the Java language and environment: portability, type safety, automatic memory management and easy network downloading of code. In this context, writing a complete operating system in Java is interesting because the whole exe...

This study presents the design and development of a novel mobile wireless system to be used for monitoring seismic events and related electromagnetic signals, employing smart mobile devices like personal digital assistants (PDAs) and wireless communication technologies such as wireless local area networks (WLANs), general packet radio service (GPRS) and universal mobile telecommunications syste...

Security in email systems involves computationally expensive public key cryptography operations. This makes it difficult to deploy secure email systems for computationally weak environments, such as personal digital assistants. To solve this problem, we have developed a secure framework in which computationally weak clients can use a trusted server to perform difficult cryptographic operations ...

This paper compares two possible scenarios for mobile Internet surfing according to the Personalised Access to Local Information and services for tOurists (PALIO) Project (IST-1999-20656). In particular, we consider WAP phones with Short Message Service (SMS) and Personal Digital Assistants (PDA) with General Packet Radio Service (GPRS). Suitable round robin scheduling schemes are analyzed for ...

In their day-to-day practice, pharmacists, graduate (pre-registration) pharmacists, pharmacy technicians, dispensing assistants and medicines counter assistants use widely available office, retail and management information systems alongside dedicated pharmacy management and electronic health (ehealth) applications. The ability of pharmacy staff to use these applications at home and at work, al...

Advances in handheld computer technology are making data collection faster, easier, and more accurate. In this article, the use of personal digital assistants (PDAs) to collect data for a study on elder neglect is described and evaluated. Methods for integrating this technology into a research study are discussed as are suggestions for increasing the performance of data collectors using these d...
