Towards Autonomous Mobile Robots for the Exploration of Steep Terrain
Steep, natural terrain offers excellent opportunities for scientific investigations into the composition and history of Mars and other planetary bodies. In this paper, we present a prototype tethered robot, vScout (vertical scout), capable of operating in steep, rugged terrain. The primary purpose of this vehicle is to support field geologists conducting research on cliffs, in canyons, and on c...
متن کاملQuasiplanar steep water waves.
A unique description for highly nonlinear potential water waves is suggested, where weak three-dimensional effects are included as small corrections to exact two-dimensional equations written in conformal variables. Contrary to the traditional approach, a small parameter in this theory is not a surface slope, but it is the ratio of a typical wavelength to a large transversal scale along the sec...
متن کاملThe Host Galaxy of GRB 990712 ⋆ , ⋆ ⋆
We present a comprehensive study of the z = 0.43 host galaxy of GRB 990712, involving ground-based photometry, spectroscopy, and HST imaging. The broad-band UBVRIJHKs photometry is used to determine the global spectral energy distribution (SED) of the host galaxy. Comparison with that of known galaxy types shows that the host is similar to a moderately reddened starburst galaxy with a young ste...
متن کاملThe Host Galaxy of Grb 970508
We present late-time imaging and spectroscopic observations of the optical transient (OT) of gammaray burst (GRB) 970508. Imaging observations roughly 200 and 300 days after the burst provide unambiguous evidence for the flattening of the light-curve. The spectroscopic observations reveal two persistent features which we identify with [O II] 3727 Å and [Ne III] 3869 Å at a redshift of z = 0.835...
متن کاملAntidunes on steep slopes
16 When increasing the rates of subcritical flow on gentle slopes, the bed successively produces 17 ripples, dunes and flat beds. Antidunes (defined here as all bed undulations for which the 18 surface gravity waves are in phase with the bed profile) appear only in high flow rates and 19 may be found in some extreme natural flow events. Inversely, on steep slopes flume 20 experiment (S≥1% appro...
