The Anatomical Record, EarlyView.Abstract Macaws are renowned for processing dry, mechanically resistant fruits, yet the species‐level anatomical and functional correlates of this performance remain incompletely resolved. We examined the feeding apparatus of the Blue‐and‐yellow Macaw (Ara ararauna) using an integrated approach that combines osteology, myology, and bite‐force estimates

Kinematic modeling and redundancy resolution for nonholonomic mobile manipulators
, 2006 We consider robotic systems made of a nonholonomic mobile platform carrying a manipulator (nonholonomic mobile manipulator, NMM). By combining the manipulator differential kinematics with the admissible differential motion of the platform, a simple and ...

Model based analysis of kinematic redundancy for increased chatter stability in robotic milling [PDF]
, 2019 Robotic milling is exposed to varying dynamic response at the tool tip due to varying serial kinematics and related dynamic properties of the robot. Therefore, stable milling conditions vary throughout the workspace based on the feed direction, as well ...

Similar locomotor patterns across Quarter Horse disciplines inform lameness assessment
Equine Veterinary Journal, EarlyView.Abstract Background Lineage‐based selection is central to the Quarter Horse industry and is often justified by the assumption that morphology determines locomotor function. However, objective evidence linking static conformation to discipline‐specific locomotor behaviour under standardised conditions remains limited.

Novel Kinematically Redundant (3+1)-DOF Delta-Type Parallel Mechanisms
RoboticsAlthough parallel mechanisms are used in various fields, their application is often limited by singularities and a restricted workspace. Kinematic redundancy is a promising approach for mitigating these issues while also extending the functionality of ...

A Review of Automatic Measurement of Learning Engagement Using Body Clues
Future in Educational Research, EarlyView.ABSTRACT Learning engagement is an overarching multifaceted construct that includes behavioral, cognitive, and emotional dimensions. The static subjective measurements may lead to inaccurate results. Considering the authenticity and reliability of body signals, this study investigated the types of body cues used in measuring learning engagement and ...
