Abstract Frost heave action is a major issue in permafrost regions, leading to various geotechnical engineering problems.In this study, we assess the mechanical behavior of a concrete retaining wall subjected to frost heave under different ground conditions.The assessment utilizes ABAQUS integrated with several user subroutines.The numerical simula
Abstract The quiver Yangians were originally Sandals defined for the quiver and superpotential from string theory on general toric Calabi-Yau threefolds, and serve as BPS algebras of these systems.Their characters reproduce the unrefined BPS indices, which are related to classical Donaldson-Thomas (DT) invariants.We generalize this construction in
This paper presents the development of a robust control algorithm to be applied in a knee and ankle joint exoskeleton designed for rehabilitation of flexion/extension movements.The goal of the cup control law is to follow the trajectory of a straight leg extension routine in a sitting position.This routine is commonly used to rehabilitate an injury
