A balance platform setup was defined for use in the determination of the center of gravity in the sagittal plane for a wheelchair and patient. Using the center of gravity information, measurements from the wheelchair and patient (weight, tire coefficients of friction), and various assumptions (constant speed, level-concrete surface, patient-wheelchair(More)
Experiments have been conducted on the UHF v/ave interactions between a plasma and an electron stream (Refs, 1 and 2), and comparisons made between the measured and calculated values of frequencies and wavelengths. The apparatus consists of a plasma source producing a plasma column 1 cm in diameter with n adjust9 13 -3 e able between 10 and 10 cm ; an(More)
