A 3D coupled model to simulate vehicle–bridge interactions (VBI) estimate its structural responses and impact factors (IMs) was developed in this study. By health monitoring (SHM) of a real concrete bridge, several data were collected calibrate the bridge by finite element method (FEM). These models provide response terms vertical displacements accelerations. VBI reliable outputs without signif...

BACKGROUND a large proportion of falls in older people occur when walking; however the mechanisms underlying impaired balance during gait are poorly understood. OBJECTIVE to evaluate acceleration patterns at the head and pelvis in young and older subjects when walking on a level and an irregular walking surface, in order to develop an understanding of how ageing affects postural responses to ...

objective: to compare the effects of two auditory methods by mother and fetus on the results of nst in 2011-2012. materials and methods: in this single-blind clinical trial, 213 pregnant women with gestational age of 37-41 weeks who had no pregnancy complications were randomly divided into 3 groups (auditory intervention for mother, auditory intervention for fetus, and control) each containing ...

Numerical simulations of self-gravitating flows evolve a momentum equation and an energy that account for accelerations gravitational releases due to time-dependent potential. In this work, we implement fully conservative numerical algorithm flows, using source terms, in the astrophysical magnetohydrodynamics framework Athena++. We demonstrate properly evaluated terms are when they equivalent d...

The problem of transient dynamics of highly flexible three-dimensional space-curved beams, undergoing large rotations and stretches, is treated. The case of conservative force loading, which may also lead to configuration-dependent moments on the beam, is considered. Using the three parameters associated with a conformal rotation vector representation of finite rotations, a well-defined Hamilto...

Accelerations and braking of vehicles can be measured and analyzed with different systems and software. In our case, we used the system G-Tech Pro Performance Meter RR w and Performance Analysis System Software (PASS). This system enables measurements of longitudinal accelerations, lateral accelerations and braking. PASS software has two options, the first is Drag Runs, which is designed for th...

In this paper, we present two main results. First, by only one conjecture (Conjecture 2.9) for recognizing a vertex symmetric graph, which is the hardest task for our problem, we construct an algorithm for finding an isomorphism between two graphs in polynomial time O(n). Second, without that conjecture, we prove the algorithm to be of quasi-polynomial time O(n ). The conjectures in this paper ...

Engineering efficiency is paramount for the introduction of novel systems and formats analysis. This work extends an accessible efficient analysis platform by combining kinematic equilibrium approach limit with single degree freedom nature a hinge-controlled masonry arch to perform dynamic modelling applied two-dimensional acceleration vectors. Utilising ideal conditions, minimum work-paths are...
