Simulation of Weightlessness

open access: closed, 1986
The phenomenon of gravitation is characterized by the mutual attraction of any two bodies. The universal character of gravitation was first recognized by Isaac Newton who found the well-known law for the attraction force F acting between two mass points or homogeneous spherical bodies $$\rm F\, = \,\gamma Mm/R^2 $$ (3.1) M, m are the masses ...

Computational simulation to understand vision changes during prolonged weightlessness

open access: closed2013 35th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2013
A mathematical model of whole body and cerebral hemodynamics is a useful tool for investigating visual impairment and intracranial pressure (VIIP), a recently described condition associated with space flight. VIIP involves loss of visual acuity, anatomical changes to the eye, and, usually, elevated cerebrospinal fluid pressure. Loss of visual acuity is
