Interseismic crustal deformation in the Taiwan plate boundary zone revealed by GPS observations, seismicity, and earthquake focal mechanisms Interseismic crustal deformation in the Taiwan plate boundary zone revealed by GPS observations, seismicity, and earthquake focal mechanisms, Tectonophysics This is a PDF file of an unedited manuscript that has been accepted for publication. As a service t...
As the depth of coal mining increases, rockbursts become more severe, and multiple rockburst accidents have previously occurred, seriously affecting mine production safety. With Hegang area as research object using field measurement numerical simulation methods, geological tectonic characteristics each impact in are analyzed to obtain stress distribution trend area. The maximum horizontal princ...
Shear-wave polarization analysis has been performed on data from twelve earthquakes recorded in central Italy. These data are part of a set of high quality seismograms recorded by a three-component digital network installed in Abruzzo region after a Ms = 5.8 earthquake on 7 May 1984. Analysis performed on 2 to 6 Hz bandpass-filtered seismograms reveals shear-wave splitting. In order to determin...
In this paper, a mathematical model is developed to simulate three-dimensional femur bone, taking into account the stress distribution and total displacement during horizontal walking. The principles of continuum mechanics, the field equations governing the displacement and stress fields in the femur bone including the stress equilibrium equations are used in the model. Realistic domain is crea...
On each trial of the primary task for the study, a pair of small circles appeared on a computer screen. Across trials, the circles appeared in an array of positions on the screen. The participant was required on each trial to indicate whether or not the test circles were two or fewer position units apart in terms of the horizontal dimension of this array. The discrimination that the task requir...
One of the most common errors of total knee arthroplasty procedure is a malrotation of tibial component. The stress on tibial insert is closely related to polyethylene failure. The objective of this study is to analyze the effect of malrotation of tibial component for the stress on tibial insert during high flexion using a finite element analysis. We used Stryker NRG PS for analysis. Three diff...
Introduction: Large volcanic edifices on Venus constitute a primary expression of the thermal evolution of that planet. Over 150 volcanic edifices with diameters > 100 km are distributed heterogeneously over the surface of Venus [1-4]. They are characterized by extensive radially oriented lava flow aprons and generally shallow flank slopes. The compositions of the lava flows that build such str...
BACKGROUND For Royal Marine recruits in training, the third metatarsal is the most common site for stress fracture. Previous evidence regarding biomechanical factors contributing to metatarsal stress fracture development is conflicting, possibly due to the lack of differentiation between the metatarsals. The present retrospective study compares static anatomical characteristics and dynamic biom...
