Call them handhelds, palm-tops, or personal digital assistants (PDAs), pocket-sized computers are becoming a common feature on the medical landscape. As the technology improves, more programs become available, and the demands of medical practice heighten, physicians are recognizing the benefits of having information available at the point of care. This article reviews the use of handheld comput...

I argue against trying to solve the problem of clustering objects into disk pages. Instead, I propose that objects be fetched in groups that may be specific to an application or user, and that can be computed at fetch time. I briefly describe crystals, which serve to record such groups statically. Finally, I speculate that object fetching may be particularly relevant for providing services to v...

Nowadays, the performance of mobile devices such as personal digital assistants (PDA) or cell phones are rapidly improving. This improvement increased the demand for various functions in mobile devices. Among them, embedded speech recognizers are one of the major research topics. To guarantee an acceptable performance, the efficient usage of the hardware resources is very important. In this pap...

Museums are playing a more active role in modern societies beyond preserving a society’s cultural heritage. They have become an important learning environment and some of them even a tourist attraction. Traditional storytelling aid for museums consisting of texts and labels may not be personalized to fit each individual personal taste and are static sources of information. This paper introduces...

This paper describes a project of providing digital assistants to support participants in an academic conference. We provided participants at the conference with a personal assistant system with mobile and ubiquitous computing technologies and facilitated communications among the participants. We also made online services available via the Web to encourage the participants to continue their rel...

The Palm OS operating system for Personal Digital Assistants (PDAs) and mobile phones has a weak security architecture, which introduces all sorts of security problems. This paper specifically targets the problem of malicious code. The main contribution of this work is the in-depth analysis of different vulnerabilities in Palm OS and the ways in which they can be exploited by malicious code. Fu...

Mobile handheld devices are becoming evermore affordable and commonplace in society. When they are involved in a security incident or crime, forensic specialists require tools that allow proper extraction and speedy examination of any digital evidence present. This paper gives an overview of forensic software tools for Personal Digital Assistants (PDA). A set of generic scenarios was devised to...

TCP/IP and World-Wide-Web (WWW) technology have become the universal standards for networking and delivery of information. Personal digital assistants (PDAs), cellular telephones, and alphanumeric pagers are rapidly converging on a single pocket device that will leverage wireless TCP/IP networks and WWW protocols and can be used to deliver clinical information and alerts anytime, anywhere. We d...

The house, office or warehouse environment is full of devices that make users’ life and work easier. People nowadays use personal computers, laptops, Personal Digital Assistants, mobile phones and many more devices with ease. The mechanism to connect, enable co-operation and exchange data between devices will help to use devices’ full capabilities. This paper investigates the usability of Commu...

To enhance scheduling efficiency and data security, we propose a Priority/MLS/AL framework for supporting transaction scheduling in wireless environments. In this framework, we divide users into three priority levels and data objects into four security levels. Mobile stations used in the experiments are cellular phones, personal digital assistants, laptops and personal computers. Altruistic loc...
