Analysis of Relative Motion between Femoral Head and Acetabular Cup and Advances in Computation of the Wear Factor for the Prosthetic Hip Joint

Acta Polytechnica, 2003
The amount and type of wear produced in the prosthetic hip joint depends on the type of relative motion between the femoral head and the acetabular cup.

Simulation of landslide movement characteristic with PFC3D and exploration of the key parameters

Shuiwen dizhi gongcheng dizhi
The accumulation layer landslide mainly composed of the slope deposits of the fourth system collapse is currently the most common type of landslide. The movement characteristic of after instability such as movement velocity and accumulation range are two

Fin stabilizer control strategy based on adaptive sliding mode

Applied Ocean Research
Ships are typically equipped with fin stabilizers to effectively weaken ship’s roll and enhance the voyage's safety. To achieve better anti-roll performance, this study proposes an adaptive sliding mode control (SMC) method for a roll reduction ...

Adaptive Fault-Tolerant Sliding Mode Control for Itô-Type Stochastic Time-Delay Markov Jump Systems with Partly Unknown Transition Probabilities

Mathematics
This study addresses the challenge of designing an adaptive sliding mode controller for a class of nonlinear Markov jump systems. These systems are characterized by unmeasurable states, partially unknown transition probabilities, and uncertainties ...

Human kinesin-5 KIF11 drives the helical motion of anti-parallel and parallel microtubules around each other

The EMBO Journal
During mitosis, motor proteins and microtubule-associated protein organize the spindle apparatus by cross-linking and sliding microtubules. Kinesin-5 plays a vital role in spindle formation and maintenance, potentially inducing twist in the spindle ...

Iterative Learning with Adaptive Sliding Mode Control for Trajectory Tracking of Fast Tool Servo Systems

Applied Sciences
To address the tracking control problem of the periodic motion fast tool servo system (FTS), we propose a control method that combines adaptive sliding mode control with closed-loop iterative learning control.

A sliding mode approach to visual motion estimation [PDF]

, 2005
A Sliding Mode Approach to Visual Motion Estimationby Burak YılmazAbstractThe problem of estimating motion and structure from a sequence of images hasbeen a major research theme in machine vision for many years and remains oneof the most challenging ones. In this work, a new approach to this problem ispresented; using sliding mode observers to estimate

Stateczność Ruchu Pewnego Mechanizmu Płaskiego z Parami Postępowymi

Engineering Transactions, 1959
The problem discussed is that of critical velocity of elements in sliding junctions. The author discusses di plane mechanism with one sliding junction, and solves the problem of local disturbances of the motion by transversal vibration of the elastic ...
