Exercise Rate Estimation using a Triaxial Accelerometer

In this paper, we propose an algorithm for the estimation of exercise rate during a variety of exercises by using measurements from triaxial accelerometry. The algorithm involves the detection of the periodicity of the body’s accelerations, and the detected periods are then fused to form an estimate of exercise rate. Experimental results demonstrate that the algorithm is effective in different ...

Standing Stability Evaluatioin Using a Triaxial Accelerometer

A triaxial accelerometer is placed at the back of the subject at the height of the center of mass. Force plate data are collected simultaneously. Subjects stand in a comfortable position with eyes open, eyes closed and doing cognitive tasks; and with feet together with eyes open and closed. The cognitive tasks are: mathematical, auditory Stroop and memory. The force plate data are processed to ...

Triaxial Galaxies with Cusps

We have constructed fully self-consistent models of triaxial galaxies with central density cusps. The triaxial generalizations of Dehnen's (1993) spherical mass models are presented, which have densities that vary as r −γ near the center and r −4 at large radii. We computed libraries of ∼ 7000 orbits in each of two triaxial models with γ = 1 (" weak cusp ") and γ = 2 (" strong cusp "); these tw...

Triaxial Black-hole Nuclei

We demonstrate that the nuclei of galaxies containing supermassive black holes can be triaxial in shape. Schwarzschild’s method was first used to construct self-consistent orbital superpositions representing nuclei with axis ratios of 1 : 0.79 : 0.5 and containing a central point mass representing a black hole. Two different density laws were considered, ρ ∝ r−γ , γ = {1, 2}. Only non-chaotic o...
