Diaphragmatic injuries are relatively rare and as such frequently missed, particularly if they occur as a rare event on the right-sided dome. Even if detected in the early phase, the concomitant injury of other organs may delay the time to repair. The delay in surgical correction may aggravate additional adherences between thoracic and abdominal organs and cause the diaphragmatic muscle to retr...

Considering backlash, time-varying mesh stiffness and radial clearance of bearing, nonlinear dynamic model of gear bearing flexible shaft system is established taking into account breathing crack in shaft and tooth wear. Nonlinear dynamic equations are solved by Runge-Kutta method. Effect of backlash, crack in shaft and tooth wear faults on the nonlinear dynamic behavior of gear-shaft-bearing s...

We show how to implement an`1 nlog n-processor EREW PRAM work-optimally on a 2-dimensional n-sided mesh of trees, consisting of n processors, n memory modules, and O(n 2) nodes. Similarly, we prove that an`2 n 2 log n-processor EREW PRAM can be implemented work-optimally on a 3-dimensional n-sided mesh of trees. By the work-optimality of implementations we mean that the expected routing time of...

We present a finite element approximation for the one-sided Stefan problem and the one-sided Mullins–Sekerka problem, respectively. The problems feature a fully anisotropic Gibbs–Thomson law, as well as kinetic undercooling. Our approximation, which couples a parametric approximation of the moving boundary with a finite element approximation of the bulk quantities, can be shown to satisfy a sta...

We focus on the programming aspect of the treatment of digitized geometries for subsequent use in mesh-free and mesh-based numerical solvers. That perspective includes the description of our C/C++ implementations which use OpenGL for the visualization and MFC classes for the user interface. We report on our experience about implementing with the IGES interface which serves as input for storage ...

We present a novel and efficient technique to generate a high quality mesh that approximates the outer boundary of a swept volume (SV). Our approach comes with two guarantees. First, the approximation is conservative, i.e. the swept volume is enclosed by the output mesh. Second, the one-sided Hausdorff distance of the generated mesh to the swept volume is upper bounded by a user defined toleran...

objectives: indicators of oral health-related quality of life (ohrqol) in children are widely adopted to evaluate the effects of oral problems. recently, the scale of oral health outcomes for 5-year-old children (soho-5) was developed based on the children’s self-reports. this study aimed to evaluate the validity and reliability of the persian version of the questionnaire in a sample of iranian...

Conccpts and techniques for thc construction of spline surfaces over irregular meshes are developed and made concrete by exhibiting a family of 0 2 surface splines. These splines extend the B-spline paradigm for the construction of parametric piecewise polynomial surfaces to control_meshe9 with non quadrila.leral cells and mOre or fewer Lhan four cells meeting at a point. In particular, the mes...

To fill an N-sided hole on a NURBS surface and to blend a corner formed by NURBS surfaces, we propose a regular N-sided open uniform quadratic subdivision surface derived by applying the open uniform quadratic subdivision scheme to a regular N-sided control mesh which is confined to the hole or to the region of the vertex blend. Boundary conditions such as C and G-continuity required for the ho...
