A system of N navigating vehicles, each associated with a start position and a goal position, may involve a large number of potential conflicts that grows exponentially with N and calls for a distributed rather than centralized control approach. This paper investigates the feasibility of a total field sensing approach for collision avoidance as an alternative to previously published techniques ...

We examine the issue of high energy scattering in generic d-dimensional quantum field theories admitting an ultraviolet fixed point. We find that the total cross section behaves asymptotically as s1−d/2(a + b/sδ), with δ ≥ (d − X)/2, X being the scaling dimension of the least relevant operator responsible for the renormalisation group flow. PACS numbers: 11.10.Jj The set of ideas which commonly...

Recently, the processing of aeromagnetic data to account for leveling has developed into the use of gradients. Utilizing multiple magnetometers allows for the measurement of magnetic gradients and minimizes the diurnal variation and other common-mode noise. We extend the use of these data to quantitative interpretation through 3D inversion. We make use of a well-known relationship between the d...
