The settlement behavior is a common problem on the railway structure that can be optimized by applying cement-treated soil as ground restoration. However, application of high cement mixing content needs proper estimation achieved adjusting element testing. strain measurement devices estimate deformation characteristics, such secant modulus, Poisson ratio, and shear modulus describe stiffness so...

This paper presents an accelerometer-based pen device for online handwriting recognition applications. The accelerometer-based pen device consists of a triaxial accelerometer, a microcontroller, and an RF wireless transmission module. Users can hold the pen device to write numerals in air without space limitations. The accelerations generated by hand motions are generated by the accelerometer e...

In this paper we contribute a novel linear-time method for extracting features from acceleration sensor signals in order to identify human activities. We benchmark this method using a standard acceleration-based activity recognition dataset called SCUT-NAA. The results show that the described method performs best when the training and testing data are from the same person. In this context, a li...

The BRST treatment of triaxial systems rotating at high spins is used to solve perturbatively the γ-independent Bohr collective hamiltonian.

Box orbits in triaxial potentials are generically thin, that is, they lie close in phase space to a resonant orbit satisfying a relation of the form lω1 +mω2 + nω3 = 0 between the three fundamental frequencies. Boxlets are special cases of resonant orbits in which one of the integers (l,m, n) is zero. Resonant orbits are confined for all time to a membrane in configuration space; they play roug...

Cone penetration resistance in sands with fines contents up to 35% is explored through drained cylindrical cavity expansion simulations with a modified MIT-S1 constitutive model. The constitutive model is calibrated to sands with 0%, 10%, 20%, and 35% low-plasticity fines with data from constant volume direct simple shear, drained and undrained triaxial compression, shear wave velocity, and 1D-...

This study investigates an application of genetic programming (GP) for modeling of coarse rotund sand– mica mixtures. An empirical model equation is developed by means of GP technique. The experimental database used for GP modeling is based on a laboratory study of the properties of saturated coarse rotund sand and mica mixtures with various mix ratios under a 100 kPa effective stresses, becaus...

This study examined the potential relationship between participation in physical activity (PA) assessed by triaxial accelerometry and physical fitness testing, including health-related and skill-related parameters of fitness, in 136 Japanese preschoolers (65 girls and 71 boys, 5.5 ± 0.6 years). In partial correlation analyses, grip strength and 20m shuttle run test were positively correlated w...
