Buckling versus unilateral constraint for a multistable metamaterial element
Philosophical Transactions Series A, Mathematical, Physical, and Engineering Sciences, 2022 A structural element is designed and investigated, forming the basis for the development of an elastic multistable metamaterial. The leitmotif of the structural design is the implementation of a strut characterized by a bifurcation occurring at either vanishing tensile or compressive load.

Discrete Unilateral Constrained Extended Kalman Filter in an Embedded System [PDF]
SensorsSince its publication in the 1960s, the Kalman Filter (KF) has been a powerful tool in optimal state estimation. However, the KF and most of its variants have mainly focused on the state estimation of smooth systems.

Realization of the brachistochronic motion of Chaplygin sleigh in a vertical plane with an unilateral nonholonomic constraint [PDF]
Theoretical and Applied Mechanics, 2023 The paper considers the procedure for determining the brachistochronic motion of the Chaplygin sleigh in a vertical plane, where the blade is such that it prevents the motion of the contact point in one direction only.

A Control Structure for Unilateral System with Communication Rate Constraint
SICE Journal of Control, Measurement, and System Integration, 2018 This study proposes a design method for unilateral control systems with communication rate constraints. In the case where it is necessary to control under a communication rate constraint, the effect of the quantization noise should be minimized using ...

On the motion of mechanical systems with unilateral constraints
Vietnam Journal of Mechanics, 1984 The motion of the system with unilateral constraints being imposed may be divised into positions, so that in certain positions the constraint is taut and the motion occurs as if the constraint was bilateral and in other positions the constraint is not ...

Geometric representation of detachment conditions in systems with unilateral constraint [PDF]
Regular and Chaotic Dynamics, 2008 Summary: Mechanical systems with unilateral constraints that can be represented in the contact mode on the phase plane are considered. On the phase plane we construct domains that satisfy the following conditions 1) a detachment from the constraint is impossible; 2) the sign of the constraint reaction corresponds to its unilateral character.

Constraint Therapy with and Without Virtual Reality for Children with Unilateral Cerebral Palsy: A Randomized Trial [PDF]
ChildrenBackground/Objectives: Cerebral palsy (CP) is the most common childhood motor disorder, with unilateral cerebral palsy (UCP) presenting with asymmetrical motor function that can cause decreased upper limb function.

Theoretical Study of a Multidimensional Pressureless Model with Unilateral Constraint [PDF]
SIAM Journal on Mathematical Analysis, 2017 Summary: The aim of this paper is to extend to multidimensions the study of a pressureless model of a gas system with unilateral constraint. Several difficulties are added with respect to the one-dimensional case. Indeed the geometry of the dynamics of blocks cannot be conserved and to solve this problem, we approximate the motion of each block by ...
