We show that the number of tropical curves of given genus and degree through some given general points in the plane does not depend on the position of the points. In the case when the degree of the curves contains only primitive integral vectors this statement has been known for a while now, but the only known proof was indirect with the help of Mikhalkin’s Correspondence Theorem that translate...

The Dante project is developing walking robots to explore inside volcanic craters. These robots face many challenges including generating a walking gait in rough, obstaclefilled terrain. For the walking robot Dante II, we implemented a gait controller to address this situation. Our approach is embodied in a network of asynchronous processes that establish a fundamental gait cycle while maintain...

Time series analysis of interferometric synthetic aperture radar data reveals coseismic and postseismic surface displacements associated with the 2007 M5.5 earthquake along the southern Ghazaband fault, a major but little studied fault in Pakistan. Modeling indicates that the coseismic surface deformation was caused by ~9 cm of strike-slip displacement along a shallow subvertical fault. The ear...

It is more common than not, for mineral processing studies to proceed via the examination of model flotation systems with the resulting data often lacking statistical verification. The resultant concentrates and tails may then be subjected to a restricted range of analyses, for diagnosis of the flotation behavior variations observed, that themselves bias the outcomes. For instance surface analy...

Seeking to accurately detect and localize fruit of any color in 3D space for selective agrobotical operations, we exploit data given by Time-of-Flight or RGB-D cameras and propose a novel shape-based fruit detector using a fruit pose reference frame relative to the viewer. Surface normals, which are shaped-based local features, are accumulated into bins of different shapes along the reference f...

As abrasive water jet (AWJ) starts to be used in industry, especially in aerospace and automotive industries extensively, getting high quality surface has become a major requirement. Being a promising non-traditional cutting process, AWJ is holding several deficiencies, which limits its extensive applications dramatically. One of the deficiencies is striation marks presented on AWJ cutting surf...

Most hole filling approaches use techniques to fill up a hole first and then to smooth it. Very few tries rebuild features on the filled surface of the original 3D model. We propose an efficient hole-filling methodology which preserves sharp features of the geometry of the original model. The main idea is that we reconstruct feature curves in the missing parts of the given mesh before filling t...

We show that outflow rates in jets directly depend on the spectral states of black holes. In particular, in soft states, when the Comptonized electrons are cold, outflow rate is close to zero. In hard states, outflow could be steady, but the rate may be very small – only a few percent of the inflow. In the intermediate states, on the other hand, the outflow rate is the highest – roughly thirty ...

The conventional K-Ar dating method was applied to the 1986 dacite flow from the new lava dome at Mount St. Helens, Washington. Porphyritic dacite which solidified on the surface of the lava dome in 1986 gives a whole rock K-Ar “age” of 0.35±0.05 million years (Ma). Mineral concentrates from the dacite which formed ins 1986 give K-Ar “ages” from 0.34±0.06 Ma (feldspar-glass concentrate) to 2.8±...
