Formation shape control for a collection of point agents is concerned with devising decentralized control laws which ensure that the formation will move so that certain interagent distances approximate prescribed values as closely as possible. Such laws are often derived using steepest descent of a potential function which is invariant under translation and rotation, and then critical formation...

The Yilgarn Banded Iron Formations of Western Australia are topographical features that behave as terrestrial islands within the otherwise flat, semi-arid landscape. The formations are characterised by a high number of endemic species, some of which are distributed across multiple formations without inhabiting the intervening landscape. These species provide an ideal context for phylogeographic...

This study examines the transformation of dalan (building-covered walkway), a distinctive historic structure found in Herat Old City, at three time points (1977-78, 2005-06, and 2019-20). The results show number dalans has been decreasing rate decrease is accelerated. Of 59 exsiting dalans, 44 were built more than 100 years ago. Most are relatively good condition, except 16 need urgent repair d...

Methods for the determination of star formation rates (SFR) from integrated populations are reviewed. We discuss the assumptions and underlying uncertainties (e.g. IMF slope, Mup, metallicity, SF history etc.) used in the calibrations of UV, FIR, Hα, and [O ii] λ3727 indicators. The “universality” of empirically calibrated indicators such as [O ii] is examined. We also present preliminary resul...

This paper presents a Lie group setting for the problem of control of formations, as a natural outcome of the analysis of a planar two-vehicle formation control law. The vehicle trajectories are described using the planar Frenet–Serret equations of motion, which capture the evolution of both the vehicle position and orientation for unit-speed motion subject to curvature (steering) control. The ...
