Predicting the movements of mobile cell phone communications systems, thus providing a guarantee of the quality of service (QoS) and offering locating services, as well as recognising imperfect texts on a dictionary basis, are two of the applications demonstrated by José Javier Astrain Escola, engineer in the Public University of Navarre. The tool that makes this task possible is one that employs fuzzy state automatas with empty chain transitions.
At the beginning of the study, this engineer found that there was very little literature on the subject: “As regards the theory fuzzy state automatas with empty chain transitions, there was no work in the literature. Regarding the classification of chains, they were presented as the most common techniques, as probabilistic types although in this PhD, we have shown that fuzzy techniques enable improved final recognition rates than these”.
It is in the mobile cellular communications systems that, “currently great efforts are being made to provide locating mechanisms, quality of service and recognition of the mobility of users with latest–generation systems such as UMTS”.

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...
