Chaotic phenomena in the trajectory control of redundant manipulators [PDF]

, 1999
Redundant manipulators have some advantages when compared with classical arms because they allow the trajectory optimization, both on the free space and on the presence of obstacles, and the resolution of singularities. For tihs type of manipulators, the

High Precision Prediction Model of Wind Speed for Underground Mine Tunnel by Using ASTF Net

Energy Science &Engineering, EarlyView.
This paper proposes an Adaptive Spectral‐Temporal Fusion Net (ASTF‐Net), which features a novel decomposition‐ensemble framework with adaptive feature fusion. This design deliberately balances spectral and temporal features and effectively boosts prediction accuracy in complex ventilation environments. ABSTRACT An Adaptive Spectral‐Temporal Fusion Net (

Computer Aided Design of a Hyper-redundant Manipulator

Advances in Electrical and Computer Engineering, 2013
Bioinspired solution can support significant improvements across various fields of robotics, offering solutions to basic problems such as locomotion and manipulation in unstructured environments. This paper deals with the problem of using a bioinspired solution in building a hyper-redundant robotic arm. In the recent period, were developed an important

A fractional perspective on the trajectory control of redundant and hyper-redundant robot manipulators

The manuscript develops a new perspective for studying the trajectory control of planar manipulators using the Moore–Penrose pseudoinverse. Different mechanical structures are compared, namely redundant and hyper-redundant robots.

Development and Preliminary Validation of a Modified Thyroid Symptom Questionnaire (TSQ)

Head &Neck, EarlyView.
ABSTRACT Background This study aimed to modify and validate the Thyroidectomy Voice and Symptom Questionnaire (TVSQ) to serve as a symptom screening tool in benign thyroid disease. Methods A 32‐item modified TVSQ was developed and administered alongside a symptom checklist to outpatients; controls were recruited to determine discriminative validity ...

JOINT DESIGN FOR A HYPER-REDUNDANT SERIAL MANIPULATOR

Proceedings of the Canadian Engineering Education Association (CEEA), 2011
We propose a joint design for a low-cost, light-weight, hyper-redundant serial manipulator. The proposed design consists of two rigid end plates connected by a universal joint; two sets of agonist/antagonist linear actuator pairs allow independent 2-DOF control.

On the optimal configuration of redundant manipulators [PDF]

, 1998
Redundant manipulators have some advantages when compared wih classical arms because they allow the trajectory optimization, both on the free space and on the presence of obstacles, and the resolution of singularities. For this type of manipulators, the

Pursuing Leadership on One's Own Terms: A Human Resource Development Perspective on Leadership Aspiration, Identity, and Organizational Influence

Human Resource Development Quarterly, EarlyView.
ABSTRACT Leadership aspiration is not simply a product of ambition or capability, but a dynamic, context‐sensitive phenomenon shaped by how individuals understand leadership and whether pursuing it feels feasible, meaningful, and sustainable. Using phenomenographic analysis of semi‐structured interviews with 23 employees and drawing on Leadership ...

Large-Scale Multiobject Emulation Platform for Noncooperative Target Missions in Space

International Journal of Aerospace Engineering
On-ground emulation is crucial to cutting-edge space technology involving the rendezvous and maintenance of noncooperative objects. However, existing systems are restricted to two objects and have a limited range of motion, and they cannot emulate some ...

The Efficiency Trap of Agentic AI in Human Resource Management

Human Resource Management, EarlyView.
ABSTRACT Agentic AI transforms HRM from data‐driven support to autonomous execution. Organizations deploy these recursive workflows to eliminate human implementation variance, yet we challenge the assumption that such alignment remains optimal. Drawing on Weick's theory of loose coupling, we argue that delegating HR execution to agentic AI creates ...
