Lately, distributed applications have been improved with the emergence of a great number of different terminals and networks. Adaptability has become a common approach to solve heterogeneity problems involved by the use of multiple devices. Indeed, we have introduced global adaptation to improve merging adaptability with distributed applications. Global adaptation allows dynamic, transparent an...

We discuss three interlinked issues: the natural pace of environmental change and adaptation, the likelihood that a population will adapt to a potentially lethal change, and adaptation to elevated CO2, the prime mover of global change. Environmental variability is governed by power laws showing that ln difference in conditions increases with ln elapsed time at a rate of 0.3-0.4. This leads to s...

Here we examine adaptation effects on pattern detection and position discrimination tasks in radial and rotational motion patterns, induced by adapting stimuli moving in the same or opposite directions to the test stimuli. Adaptation effects on the two tasks were similar, suggesting these tasks are performed by the same population of neurons. Global motion specific adaptation was then induced b...

the error of inertial navigation systems increase versus time, therefore for achieving higher accuracy specially in long time navigations we have to use an aiding system. global positioning system is the best aiding system in this case. in this paper we first simulate a gps and ins; then simulate tightly integration and finally review adaptation method of kalman filtering a fuzzy adaptive kalma...

The perception of speed is dependent on the history of previously presented speeds. Adaptation to a given speed regularly results in a reduction of perceived speed and an increase in speed discriminability and in certain circumstances can result in an increase in perceived speed. In order to determine the relative contributions of the local and global speed components on perceived speed, this e...
