This paper presents an overview of recent research into a new method of providing fault tolerant actuators for high-integrity and safety-critical applications. The High Redundancy Actuator (HRA) uses a large number of small actuation elements to make up a single actuator. It provides superior reliability and efficiency over current technology, by configuring and controlling the elements so that...

This work aims to pave the way for high availability in high-performance computing (HPC) by focusing on efficient redundancy strategies for head and service nodes. These nodes represent single points of failure and control for an entire HPC system as they render it inaccessible and unmanageable in case of a failure until repair. The presented approach introduces two distinct replication methods...

With the deployment of larger and larger distributed storage systems, data reliability becomes more and more of a concern. In particular, redundancy techniques that may have been appropriate in small-scale storage systems and disk arrays may not be sufficient when applied to larger scale systems. We propose a new mechanism called delayed parity generation with active data replication (DPGADR) t...

In this letter, we present a novel inverse kinematics (IK) solution for robotic arm-hand system to achieve precision grasp. This problem is kinematically over-constrained and address the issue solve problem, propose new approach with three key insights. First, human-inspired thumb-first strategy consider one finger of hand as “thumb” narrow down search space increase success rate our algorithm....

BACKGROUND The redundancy hypothesis predicts that the species redundancy in a plant community enhances community stability. However, numerous studies in recent years questioned the positive correlation between redundancy and stability. METHODOLOGY We explored the relationship between the species redundancy, functional redundancy and community stability in typical steppe grassland in Northern...
