Statistical analyses of transmission vibration patterns from an AH-1 Cobra helicopter were previously reported. Fourteen steady-state maneuvers were analyzed using multi-factor analysis of covariance. Based on triaxial recordings, it was found that only two maneuvers displayed reliably stationary time-series: low and high power forward climb. Principal Components Analysis of the triaxial RMS da...

Sample wafers of compounded dental gutta-percha and uncompounded dental-grade gutta-percha were compression tested to 20,000 pounds in uniaxial and triaxial systerns. Unrestrained flow in the uniaxial series prevented development of stress levels sufficient to produce molecular compression. Negligible molecular compression did occur in the triaxial series but only above a stress level of approx...

A nonlinear isotropic elastic block is subjected to a homogeneous deformation consisting of simple shear superposed on triaxial extension. Two new relations are established for this deformation which are valid for all nonlinear elastic isotropic materials, and hence are universal relations. The first is a relation between the stretch ratios in the plane of shear and the amount of shear when the...

In this review we examine the dynamics and gravitational wave detectability of rotating strained neutron stars. The discussion is divided into two halves: triaxial stars, and precessing stars. We summarise recent work on how crustal strains and magnetic fields can sustain triaxiality, and suggest that Magnus forces connected with pinned superfluid vortices might contribute to deformation also. ...

in the present investigation, the cyclic load deformation behaviour of soil-fly ash layered system isstudied using different intensities of failure load (i = 25%, 50% and 75%) with varying number of cycles (n =10, 50 and 100). an attempt has been made to establish the use of fly ash as a fill material for embankments ofhighways and railways and to examine the effect of cyclic loading on the lay...

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 ...
