Evaluating condylar distraction potential: a comparison between patients with unilateral disc displacement without reduction and asymptomatic volunteers [PDF]

BMC Oral Health
Purpose This study aimed to evaluate and compare the condylar distraction potential and joint space dimensions between patients with unilateral disc displacement without reduction (DDwoR) and asymptomatic individuals, using dynamic jaw tracking and MRI ...

Discrete Unilateral Constrained Extended Kalman Filter in an Embedded System [PDF]

Sensors
Since 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.

The Existence Problems of Solutions for a Class of Differential Variational–Hemivariational Inequality Problems

Mathematics, 2023
In this work, we used reflexive Banach spaces to study the differential variational—hemivariational inequality problems with constraints. We established a sequence of perturbed differential variational–hemivariational inequality problems with perturbed ...

Modelling and Numerical Solution of the Problem with Unilateral Constraints and Friction under Dynamic Action of the Load

Наука и техника, 2021
Problems with unilateral constraints are not uncommon in the practice of calculating  building construction and structures. Certain difficulties in solving them arise during contact friction, as well as the dynamic action of the load.

Optimal Control Problems for Set-Valued Quasivariational Inequalities with Applications

Mathematics, 2022
In this paper we investigate the optimal control problem for set-valued quasivariational inequality with unilateral constraints. Under suitable conditions, we prove that the solution to the current optimal control problem converges to a solution to old ...

Frictional contact problem in building constructions analysis

Magazine of Civil Engineering, 2020
The article discusses the contact interaction of deformable building constructions or their parts. Such interaction is realized for example at: hydraulic structures; suspension pile foundations, girder, raft, sheet piling; friction bearings and kinematic

Modelling of contact interaction of structures with the base under dynamic loading

Инженерно-строительный журнал, 2019
Constructively nonlinear problems with unilateral constraints are frequent in the calculation of various structures. At the same time, certain difficulties cause problems with the contact friction, as well as with the dynamic action of the load.

A Multivalued Variational Inequality with Unilateral Constraints [PDF]

, 2016
The present paper represents a continuation of [3]. There, we studied a new class of variational inequalities involving a pseudomonotone univalued operator and a multivalued operator, for which we obtained an existence result, among others. In the current paper we prove that this result remains valid under significantly weaker assumption on the ...
