Contour Parametrization via Anisotropic Mean Curvature Flows
, 2018 We present a new implementation of anisotropic mean curvature flow for contour recognition. Our procedure couples the mean curvature flow of planar closed smooth curves, with an external field from a potential of point-wise charges.

Analysis of wedge penetration in clay [PDF]
, 1976 A variety of devices designed to penetrate soil is used in soil engineering practice to measure soil properties or to emplace instrumentation, although the mechanics of the steady state penetration process is not well understood.

Journal of Fish Biology, Volume 108, Issue 1, Page 128-163, January 2026.Abstract Recent molecular studies have advanced our knowledge of the taxonomic diversity and generic placement of the slender stonebashers, previously placed in the genus Hippopotamyrus, in southern Africa. These fishes were recently transferred to the genus Heteromormyrus whose range encompasses the Kwanza, Kunene, Okavango, Zambezi, Pungwe and Buzi ...

Journal of Robotics, Volume 2026, Issue 1, 2026.Trajectory planning and control of bionic dual‐arm underwater robotic manipulators (BDA‐URMs) are highly challenging due to the complex interactions between the manipulator’s base, its dual arms, and the nonlinear underwater dynamics. This study proposes a novel hybrid controller to enhance trajectory tracking and control of a BDA‐URM.

Base reaction optimization of redundant manipulators for space applications [PDF]
One of the problems associated with redundant manipulators which were proposed for space applications is that the reactions transmitted to the base of the manipulator as a result of the motion of the manipulator will cause undesirable effects on the ...
