Enabling Astronaut Self-Scheduling using a Robust Advanced Modelling and Scheduling system: an assessment during a Mars analogue mission
Michael Saint-Guillain, Jean Vanderdonckt, Nicolas Burny +14
Human long duration exploration missions (LDEMs) raise a number of technological challenges. This paper addresses the question of the crew autonomy: as the distances increase, the…
Euler's and the Taxi Cab relations and other numbers that can be written twice as sums of two cubed integers
Vladimir Pletser
We show that Euler's relation and the Taxi-Cab relation are both solutions of the same equation. General solutions of sums of two consecutive cubes equaling the sum of two other cu…
Annular structures in perturbed low mass disc-shaped gaseous nebulae I : general and standard models
Vladimir Pletser
Abstract This is the first of two papers where we study analytical solutions of a bidimensional low mass gaseous disc slowly rotating around a central mass and submitted to small r…
Annular structures in perturbed low mass disc-shaped gaseous nebulae II : general and polytropic models
Vladimir Pletser
This is the second of two papers where we study additional analytical solutions of a bidimensional low mass gaseous disc rotating around a central mass and submitted to small radia…
Congruence Properties of Indices of Triangular Numbers Multiple of Other Triangular Numbers
Vladimir Pletser
It is known that, for any positive non-square integer multiplier , there is an infinity of multiples of triangular numbers which are triangular numbers. We analyze the congruenc…
Closed Form Equations for Triangular Numbers Multiple of Other Triangular Numbers
Vladimir Pletser
Triangular numbers that are multiple of other triangular numbers are investigated. It is known that for any positive non-square integer multiplier, there is an infinity of multiple…
