The study of how to model the relationship between echoes and physical surrounding is relatively new, with scientists turning to the problem within the past decade.
It allows to predict the path loss by a statistical analysis of measurements in a given physical surrounding: mathrm{PL}(d)=mathrm{PL}left({d}_0right)+10eta cdot { log}_{10}frac{d}+{X}_{sigmasigma } (2 where PL(d 0) is the path loss for a reference distance d 0, η is the path loss exponent, and X σ is a Gaussian random variable with zero mean and a standard deviation σ.
This paper proposes a Context-Aware Driver Assistance System that links drivers with the physical environment surrounding them.
Personalized walkability index values will be calculated and constructed for adults and children based on the physical environment surrounding each participant's place of residence.
Forces shaping a person's identity, Veblen said, may often be genetic, cultural and social, but they can also include the surrounding physical environment.
Even in dreams, it generates a reality, replete with a functioning body that interacts with a surrounding physical environment.
An abrupt topographic elevation, such as a seamount, over a flat deep bottom produces profound effects on the surrounding physical environment (in the form of upwellings, turbulence, Taylor cones, eddies,.) and, in turn, on the local dynamics of plankton and benthos [2], [3], [4].
Cell adhesion is a critical process that mediates cell communication with its surrounding physical environment via many complex extracellular and intracellular interactions.
Consequently, parasitic plants have a tremendous impact on community ecology among plants, animals, microbes, and even the surrounding physical environment [ 7].
The novelties of this work are itemized as follows: (i) It is proposed a Bayesian approach for understanding the physical and non-physical surrounding areas of moving agents based on their nonlinear dynamics.
