Ubiquitous Commerce - Always On, Always Aware, Always Pro-active
The development of the infrastructure for ubiquitous computing is progressing rapidly, yet the applications that will be built on this new infrastructure remain largely ill defined. What will we do with these emerging capabilities? Stock quotes in 3-D on your heads-up display? Sports scores in stereo sound? We believe that the new kinds of services will result from three primary capabilities of...
متن کاملGrowing older does not always mean moving slower: examining aging and the saccadic motor system.
Although humans typically move more slowly as they age, one exception may be the saccadic motor system. To fully determine whether the execution of saccades is affected by age, the authors examined detailed kinematics of vertical and horizontal saccades across a range of saccadic amplitudes (4 degrees, 8 degrees, and 12 degrees). Ten younger and 20 older adults participated in each experiment. ...
متن کاملInvestigation of Always Present and Spectrum Sensing based Incumbent Emulators
Cognitive radio (CR) technology has been suggested for effective use of spectral resources. Spectrum sensing is one of the main operations of CR users to identify the vacant frequency bands. Cooperative spectrum sensing (CSS) is used to increase the performance of CR networks by providing spatial diversity. The accuracy of spectrum sensing is the most important challenge in the CSS process sinc...
متن کاملIs the Detection of Odontoma Always Comfortable? A Case Report
Abstract Odontomas are the most common type of odontogenic tumors, which are often discovered by routine radiographic images or after taking films to determine the main cause of the tooth failure eruption or malocclusion. The present study aimed to describe a case of misdiagnosis and similarity of foreign body density in the radiographic appearance to odontoma in a 13-yea...
متن کاملGroup Knowledge Isn't Always Distributed (neither Is It Always Implicit)
In this paper we study the notion of group knowledge in a modal epistemic context. Starting with the standard de nition of this kind of knowledge on Kripke models, we show that this de nition gives rise to some quite counter-intuitive behaviour. Firstly, using a strong notion of derivability, we show that group knowledge in a state can always, but trivially be derived from each of the agents' i...
