New architectural guidelines to assist programmers develop wireless Internet services for 3G devices such as PDAs, camera-phones, data terminals, etc and overcome difficulties such as reduced screen sizes, varying bandwidth, handling mobility etc. were demonstrated by project WISE.
The main purpose of the architectural guidelines is to provide a unified and organised approach to the description of the software architecture. The architecture is described both from an abstract conceptual perspective and a detailed concrete one. “We use three iterations to produce a description,” says Maurizio Morisio, coordinator of this IST programme-funded project. “In each iteration we produce three papers: an abstract implementation of the service, an analysis of the processes to develop the services and architecture to support the services, and guidelines for devices. The latter specifies how to handle various characteristics that may impinge upon the services offered, such as variations in screens used, absence or presence of a keyboard or mouse, and so on.”
In practice, its quite complex having a generalised architecture, so WISE is using typical architectures. “We have two architectures,” says Morisio. “One corresponds to a J2ME Java Fat Client, and the other to a Thin Client which has a simpler user interface.”
In parallel with the work on architectures, WISE pilot trials have demonstrated two prototype services. “One is a game that uses mobile phone GPRS data connections, and which is played by more than one player,” says Morisio. “The second is an online trading application for high-volume share trading. It runs on a mobile phone, and is a reduced version of the RealTick service that provides a real-time display of current share prices.”

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
