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...

Abstract The paper presents an experimental study on the effect of plastic fines content undrained behavior and liquefaction susceptibility sand-fines mixtures under cyclic loading. results triaxial tests conducted Hostun sand with varying amounts (0–20%) types (kaolin calcigel bentonite) are presented. specimens were prepared different initial densities using moist tamping method, consolidated...

An interlayer soil in ancient rail tracks was identified as a mixture of ballast grains and subgrade fines. As the permanent strain $${\varepsilon }_{1}^{p}$$ such affected by water content, cyclic triaxial tests were performed, under varying contents fines wf coarse grain fv. Comparison between present previous studies showed significant effect sample preparation method on . In study, constant...

One of the main issues in design bases and foundations on water-saturated soils conditions possible seismic impacts is geotechnical substantiation possibil-ity construction. Among influencing factors, one can single out assessment ability sandy soil to resist vibration liquefaction. The paper presents re-sults studying behavior samples under triaxial cyclic loading, which equivalent strength ac...

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...

In this paper, the possibility of using fine scrap tyre rubber to improve mechanical properties soil subjected cyclic loading is addressed. Ground (0.1–0.8 mm) in various proportions (0, 9, 33% and 100% by weight) was mixed with a uniform river sand lean clay. Cyclic triaxial tests bender elements were executed observe behaviour materials also determine damping shear stiffness parameters. The r...

We conducted GDS dynamic triaxial tests to study the change rules of hysteresis curve morphology, axial strain, elastic modulus, and damping ratio waste tire rubber-mixed sand-based subgrade model samples with different rubber particle sizes, mixing amounts, loading times. The research revealed developmental rule curves rubber-mixed-sand under cyclic loading. From analyses comparison stress–str...

The design of Municipal Solid Waste (MSW) landfills requires the selection of representative MSW material properties. The profession’s understanding of the mechanical response of MSW has evolved significantly in recent years, but many aspects of the response of MSW remain uncertain. A research project involving five organizations was conducted to systematically evaluate the factors that affect ...

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...
