A liquid spherical droplet impulsively accelerated by a gaseous flow is simulated in order to investigate the drag force and the deformation. The dynamics of the droplet immersed in a gaseous flow are investigated by solving the incompressible Navier-Stokes equations using a finite volume staggered mesh method coupled with a moving mesh interface tracking scheme. The benefit of the current sche...

The Arbitrary Lagrangian-Eulerian (ALE) methods are becoming very popular for simulations of laser-plasma simulations. A typical ALE method consists of three steps: a Lagrangian solver, advancing the solution to the next time step; a rezoner, improving geometrical quality of the computational mesh; and a remapper, interpolating conservatively all fluid quantities from the Lagrangian to the rezo...

Larval and adult bullfrogs, Rana catesbeiana (Shaw), were exposed to 28 days of normoxia (PO2 150 mmHg), hypoxia (PO2 70-80 mmHg) or hyperoxia (PO2 greater than 275 mmHg) at 20-23 degrees C, after which the following morphological measurements were made: (1) mass, thickness, capillary mesh density and blood-water barrier of the skin; (2) mass, volume, cava density and blood-gas barrier of lungs...

  Purpose: Mesh technique is the standard for inguinal hernia repair because of less recurrence,   but it is inferior or equal to sutured technique in case of other post-operative complications   such as chronic pain. This clinical trial set out to compare these two techniques.   Materials and Methods: A total number of 322 cases of unilateral inguinal hernia in participants   older than 18 yea...

The problem of defining a model for deformable objects which allows the user to perform cuts is still open. Generally speaking, the reason is that such a task affects the connectivity and the topology of the mesh, while the assumption that they never change is the basis of most algorithms for both computation of deformation and collision detection. The drawback of approaching this problem as on...

Recent work in voice synthesis has implemented two-dimensional digital waveguide-mesh models of sound propagation in the vocal tract. The present work explores whether extending the models into the third dimension using data from MRI scans increases the accuracy of the model, and whether the new model is computationally feasible for real-time simulation. It is found that when using an existing ...

403 Fig. 4. The response of the performance function J(u). function has almost only one peak. This means that the decreasing direction for the entropy is toward having a narrow shape of the output probability density function. This is in line with the theoretical analysis as a small entropy means the uncertainty of the output is small, which indicates that the shape of the output probability de...

We describe a simple and effective coding scheme for insertion/deletion channels. It is based on runlength coding which converts a class of insertion/deletion channels that have infinite memory into memoryless channels, which are much easier to handle. Runlength coding is then combined with powerful error correction low-density parity-check (LDPC) codes designed for memoryless channels. We cons...

This paper studies the feasibility of acquiring the multiple source-receiver transfer functions for the prediction of pass-by noise Sound Pressure Level (SPL) of vehicles with the Fast Multipole Boundary Element Method (FMBEM). Employing measurements and simulations, the influence of frequency resolution, mesh density, mesh accuracy and solver accuracy on the computation time and on the overall...

In this paper, a novel hole-filling algorithm for triangular meshes is proposed. Firstly, the hole is triangulated into a set of new triangles using modified principle of minimum angle. Then the initial patching mesh is refined according to the density of vertices on boundary edges. Finally, the patching mesh is optimized via the bilateral filter to recover missed features. Experimental results...
