Self-Motivated Multi-Agent Exploration [PDF]

open access: yesarXiv, 2023
In cooperative multi-agent reinforcement learning (CMARL), it is critical for agents to achieve a balance between self-exploration and team collaboration. However, agents can hardly accomplish the team task without coordination and they would be trapped in a local optimum where easy cooperation is accessed without enough individual exploration.

Space Exploration [PDF]

open access: yes, 2011
The use of outer space is of growing strategic and technological relevance. The development of robotic exploration to distant planets and bodies across the solar system, as well as pioneering human space exploration in earth orbit and of the moon, paved ...

Effect of Tilted Misalignment on Tribo-Characteristics of High-Speed Ball Bearings in Liquid Hydrogen

open access: yesTribology Online, 2010
When radial load applied to the bearings was high, ball excursion occurring in the retainer ball-pockets became large due to ball-speed-variation (BSV). Such BSV was also caused by inclination of the outer race to the shaft (tilted misalignment).

Toward Designing Social Human-Robot Interactions for Deep Space Exploration [PDF]

open access: yesarXiv, 2021
In planning for future human space exploration, it is important to consider how to design for uplifting interpersonal communications and social dynamics among crew members. What if embodied social robots could help to improve the overall team interaction experience in space?

Wide-address spaces [PDF]

open access: yesACM SIGOPS Operating Systems Review, 1993
In a recent issue of Operating System Review, Hayter and McAuley [1991] argue that future high-performance systems trade a traditional, bus-based organization for one where all components are linked together by network switches (the Desk-Area Network).

Improvement of Durability of Hybrid Ceramic Ball Bearings in Liquid Hydrogen at 3 Million DN (120,000 rpm)

open access: yesTribology Online, 2010
The durability of a hybrid ceramic 25-mm-bore ball bearing having a single outer land-guided retainer was evaluated and improved in liquid hydrogen at speeds up to 120,000 rpm (120,000 min-1) (3 million DN) by comparing the propagation of superficial ...

Cluster-Based Heuristic for High Level Synthesis Design Space Exploration

open access: yesIEEE Transactions on Emerging Topics in Computing, 2018
High Level Synthesis (HLS) frameworks allow to describe hardware designs in a high-level language (C/C++), without burdening developers with the error-prone task of specifying their implementation in detail.

Karst Cave as Terrestrial Simulation Platform to Test and Design Human Base in Lunar Lava Tube

open access: yesSpace: Science & Technology, 2022
Developing efficient approaches to building a suitable environment for humans on the moon play a key role in future long-term sustainable lunar exploration activities, which has motivated many countries to propose diverse plans to build a lunar base. The
