Objective: This investigation aimed to compare the effect of neuromuscular, strength and combined training on dynamic balance and sports performance including sprint, agility and power abilities in female basketball players. Method: In this semi-experimental study, 42 female professional basketball players (age 19-25 years) were assigned to three groups (neuromuscular (NM), strength (ST), and ...

Abstract The orthometric height has an essential role in a variety of civil engineering projects and it is defined as the length curved plumbline from point (on earth surface) to its intersection with geoid surface. Leveling process considered most accurate technique for obtaining these heights. However, regardless potentials, tedious, costly, time consuming. Recently many organizations researc...

using tidal potential, the effect of tide on the gravity field, crustal deformation due to tidal force, and gravity variations resulted from the crustal deformation are presented. tidal potential is divided into constant and periodic (diurnal and semi-diurnal) constituents, and for each constituents crustal displacements in radial, south-north, and east-west directions are computed. the aforeme...

The differences between gravity anomalies and gravity disturbances are numerically investigated in this study. In particular, we demonstrate how the topography, atmosphere and mass irregularities enclosed within the geoid contribute to these differences. The numerical analysis is conducted at the area of study in the Canadian Rocky Mountains. Results reveal that the dominant contributions due t...

The 2-point function is the natural object in quantum gravity for extracting critical behavior: The exponential fall off of the 2-point function with geodesic distance determines the fractal dimension dH of space-time. The integral of the 2-point function determines the entropy exponent γ, i.e. the fractal structure related to baby universes, while the short distance behavior of the 2-point fun...

precise geoid determination on islands suffers from the lack of accurate gravity data on the open seas. nowadays, sub-microgal accuracy for the land gravity observations is obtainable. but the sea gravity data which are collected via shipborne techniques, due to the measuring environment at sea area, are usually highly noisy and are contaminated with various systematic errors. on the other hand...

gravity acceleration data have grand pursuit for marine applications. due to environmental effects, marine gravity observations always hold a high noise level. in this paper, we propose an approach to produce marine gravity data using satellite altimetry, high-resolution geopotential models and harmonic splines. on the one hand, harmonic spline functions have great capability for local gravity ...

The satellite gravity mission GOCE measured the second-order derivatives of the Earth’s gravitational potential with high accuracy. The GOCE data enrich our gravity field knowledge especially at spatial resolutions from 750km down to 80km. In this paper we carry out regional gravity field analysis using radial localising basis functions that permit the combination of different data types tailor...
