In order to achieve the aim of the study, the soil was investigated with a
triaxial pressure apparatus, direct shear apparatus and oedometer testing apparatus.
These hulls are all hand laid multi-directional biaxial and
triaxial glass bonded to a uni-grid stringer system and carbon fiber reinforced.
Triaxial accelerometers are highly responsive motion sensors used to determine the magnitude and frequency of movement in three dimensions (mediallateral, anterior-posterior, and vertical), and have been previously used to assess energy expenditure, (21) step count, (21,22) physical activity levels, (23) and acceleration.
At the same time, many scholars believed that the physical and mechanical properties of sandy pebble soil of different coarse-grained content such as cohesion, internal friction angle and permeability had a great impact (Wei et al., 2008; Yasin et al., 2017).Most of them conducted studies on macromechanical properties of sandy pebble soil using the
triaxial test and direct shear test but lacking micromechanical parameters of the composite structure of sand and pebble particles.
[7] have developed a fall detection system based on a barometric pressure sensor and a
triaxial accelerometer located on the waist.
Rock reservoir in subsurface energy resources is under
triaxial stress condition, and hydraulic fracking is used to generate fluid transport path for the production of hydrocarbon and geothermal energy [1].
In general, direct shear tests and
triaxial compression tests are carried out to investigate the shear strength characteristics of fiber-reinforced soil.
The study, led by investigators at Brigham and Women's Hospital, investigated physical activity of women measured over seven days using a wearable device called a
triaxial accelerometer.
This is one of the first studies to investigate physical activity, and a clinical outcome, using the newer generation
triaxial wearable devices which have increased sensitivity to recognize physical activity and are capable of more precise measurements than the previously used uniaxial devices, or studies relying on self-reports only.
The MFL tools have
Triaxial Sensors and can be combined with Deformation Tools and an IMU to provide a full combo tool inspection.
