چکیده

We describe our work in progress aimed at implementing a multi-hat PDA. Our current prototype is based on SELinux and KDE and accepts a proximity token, in the form of a Bluetooth cellphone, as an alternative authentication method. We analyse in detail the suitability of several alternatives for the graphical environment and underlying OS and we discuss a variety of interesting implementation issues that arose

One User, Many Hats; and, Sometimes, No Hat: Towards a Secure Yet Usable PDA

How can we design a PDA that is at the same time secure and usable? In current implementations the two properties are mutually exclusive. Because normal users find password entry inconvenient, the balance usually shifts away from security, leaving the PDA vulnerable if lost or stolen. We begin by envisaging what an ideal PDA authentication mechanism might look like and by carefully examining al...

A PDA Interface for 3D Interaction with an Outdoor Robot

When looking at a coarse map of an unknown area, it is difficult to quickly orient and get a good feeling for the surrounding environment. This is especially true on a tiny Portable Digital Assistant (PDA), where it is difficult to grasp the extent of the entire map due to the small format. I therefore got the assignment to develop a Graphical User Interface (GUI) for a larger PDA and to take a...

Distributed probabilistic data association detector with turbo base-station cooperations in multi-user multi-cell MIMO systems

We address the severe interference condition with unity frequency re-use factor in each cell and propose a novel distributed receiver for reliable detection of the uncoded data transmitted in multi-user multi-cell multiple input, multiple output (MIMO) systems. The new algorithm employs distributed probabilistic data association (PDA) with turbo base-station (BS) cooperations (PDA-TB). From a B...

Factors influencing implementation of a patient decision aid in a developing country: an exploratory study

BACKGROUND Most studies on barriers and facilitators to implementation of patient decision aids (PDAs) are conducted in the west; hence, the findings may not be transferable to developing countries. This study aims to use a locally developed insulin PDA as an exemplar to explore the barriers and facilitators to implementing PDAs in Malaysia, an upper middle-income country in Asia. METHODS Qua...

Patron‐Driven Acquisition Practices of U.S. Research Libraries: East vs. West

During the past few years, Patron Driven Acquisition, or PDA, has become the catchword at library conferences, increasingly promoted by some as the answer to shrinking budgets and the new normal for developing library col‐ lections. On one level, the debate over PDA is just an extension of the old question of just in time versus just in case collecting; however, technological developments have ...
