Sliding Mode Momentum Observers for Estimation of External Torques and Joint Acceleration

IEEE International Conference on Robotics and Automation, 2019
Interactions between robots and their environment give rise to external wrenches acting on the robot structure. The estimation of the resulting torques in the joints is fundamental in human-robot interaction to detect/identify collisions and perform ...

Remote Assessment of Ataxia Severity in SCA3 Across Multiple Centers and Time Points

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Spinocerebellar ataxia type 3 (SCA3) is a genetically defined ataxia. The Scale for Assessment and Rating of Ataxia (SARA) is a clinician‐reported outcome that measures ataxia severity at a single time point. In its standard application, SARA fails to capture short‐term fluctuations, limiting its sensitivity in trials.

Longitudinal excursion and strain in the median nerve during novel nerve gliding exercises for carpal tunnel syndrome [PDF]

, 2007
Nerve and tendon gliding exercises are advocated in the conservative and postoperative management of carpal tunnel syndrome (CTS). However, traditionally advocated exercises elongate the nerve bedding substantially, which may induce a potentially ...

Sliding Joints And Soil-Structure Interaction

, 2011
Use of a sliding joint is an effective method to decrease the stress in foundation structure where there is a horizontal deformation of subsoil (areas afflicted with underground mining) or horizontal deformation of a foundation structure (pre-stressed foundations, creep, shrinkage, temperature deformation).

Elevated Connectivity During Language Processing Is Associated With Cognitive Performance in SeLECTS

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Self‐Limited Epilepsy with Centrotemporal Spikes (SeLECTS) is associated with language impairments despite seizures originating in the motor cortex, suggesting aberrant cross‐network interactions. Here we tested whether functional connectivity in SeLECTS during language tasks predicts language performance.

Dual-Arm Coordinated Control Strategy Based on Modified Sliding Mode Impedance Controller

Sensors, 2021
To meet the high-accuracy position/force control requirements of dual-arm robots for handling a target object, a control algorithm for dual-arm robots based on the modified sliding mode impedance controller MSMIC(tanh) is proposed. First, the combinative

Volume changes of concrete in interaction with sliding joint

Modern Building Materials, Structures and Techniques (MBMST), 2019
The paper describes volume changes of cement plain concrete and steel fiber reinforced concrete with strength class C 30/37 in interaction with sliding joints. In the research experiment was performed large-dimensional specimens, on which volume changes were measured using string strain gauges.
