The use of underwater dynamometry to evaluate two space suits [PDF]

open access: yes
Four Astronauts were instrumented and donned one of three extravehicular activity (EVA) suits: the currently in use shuttle suit (STS), the Mark III (MK3), and the AX5. The STS was used as the comparison suit because of approved status.

Application Possibilities of Orthophoto Data Based on Spectral Fractal Structure Containing Boundary Conditions

open access: yesRemote Sensing
The self-similar structure-based analysis of digital images offers many new practical possibilities. The fractal dimension is one of the most frequently measured parameters if we want to use image data in measurable analyses in metric spaces. In practice,

Motion Control of Siro: The Silo Cleaning Robot

open access: yesInternational Journal of Advanced Robotic Systems, 2015
Both the principle of operation and the motion-control system of a suspended robot for surface cleaning in silos are presented in this paper. The mechanical design is a reasonable compromise between basically contradictory factors in the design: the ...

More About N2O-Based Propulsion and Breathable-Gas Systems [PDF]

open access: yes
A concept was evaluated of using nitrous oxide as (1) a monopropellant in thrusters for space suits and spacecraft and (2) a source of breathable gas inside space suits and spacecraft, both by exploiting the controlled decomposition of N2O into N2 and O2.
