We present fully nonparametric estimates of the frequency function of elliptical galaxy intrinsic shapes under the axisymmetric and triaxial hypotheses. If elliptical galaxies are assumed to be oblate or prolate, the frequency function of intrinsic shapes is negative for axis ratios near unity due to the lack of apparently round galaxies. Both axisymmetric hypotheses are found to be inconsisten...

A triaxial alveolar gas diagram to depict fractional concentration of oxygen, carbon dioxide and nitrogen is described, in which the R = 1 line is always implicit. Although it is not claimed that this representation leads to new insights into respiratory physiology, a method of plotting on a triaxial coordinate system has been found to be well suited to many applications when a direct display o...

STUDY OBJECTIVE To determine the reliability, validity, and stability of a triaxial accelerometer for walking and daily activity measurement in a COPD sample. DESIGN Cross-sectional, correlational, descriptive design. SETTING Outpatient pulmonary rehabilitation program in a university-affiliated Veterans Affairs medical center. PARTICIPANTS Forty-seven outpatients (44 men and 3 women) wit...

This paper studied the method for motion tracking of arm using triaxial accelerometer, triaxial gyroscope and electronic compass. The motion model of arm is established. The hardware of tracking system of arm is designed. The track method of arm gesture based on multi-sensors data fusion is analyzed. The compensation algorithm for motion accelerations is researched. The experimental results dem...

We show that a triaxial atomic force microscopy probe creates a noncontact trap for a single particle in a fluid via negative dielectrophoresis. A zero in the electric field profile traps the particle above the probe surface, avoiding adhesion, and the repulsive region surrounding the zero pushes other particles away, preventing clustering. Triaxial probes are promising for three-dimensional as...

We developed a three-dimensional finite-difference codes which can simulate the fully triaxial induction tool in a stratified, cross-bedded anisotropic formation. The sensitivity of the fully triaxial induction measurements in cross-bedded anisotropic formation is studied for the first time. The results show that the tensor measurements are sensitive to the formation resistivity anisotropy, for...

The true shapes of the globular clusters (GCs) in M 31 have been derived from observed ellipticities. The nonparametric kernel estimates for the axis ratios distributions in the case of oblate or prolate spheroid hypothesis and the parametric estimates in the case of triaxial ellipsoid hypothesis have been used. The cluster shapes are inconsistent with the oblate/prolate hypothesis and only the...

SYNOPSIS Results of unconsolidated-undrained triaxial tests, field vane shear tests and cone penetration tests have been used to develop correlations between undrained shear strength and cone resistance for a soft to medium alluvial clay in the Lopez Canyon area of San Diego. When comparing uu triaxial results with cone resistance, the average cone factor was 11 with a standard deviation of 1.5...

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...
