Therefore regularization techniques are applied, yielding solutions that are robust against noise and that are correct for a limited class of curve velocity fields. It is shown in the paper that regularization problems, such as the smoothest velocity field computation and the computation of the ...
An efficient, scalable parallel implementation of any process requires that both the computation and the required data be evenly distributed across the available processors while minimizing the communication between processors. The movement of the grids and the time variation in the holes being cut, as...
In this equation, K1and K2are some fixed factors. Under these assumptions the speedup curve is shown in the following figure. It is interesting to note that in this case the speedups peak out. After a certain point adding more processors is detrimental to performance as shown in the following...

Stream surfaces can reveal complex flow behaviors that are not available on streamlines, but their construction algorithm is also more sophisticated. A common strategy is to sample a series of streamlines from a seeding curve and stitch the neighboring streamlines to form surfaces. To maintain a ...
During this period, it drives through the uphill and downhill sections, curve sections, and Y-shaped sections with heavy loads, and avoids conflicts with other trucks. When the unloading site is reached, the truck backs up approaches the designated unloading berm, and automatically lifts the ...
Supports C, C++, Fortran; For a given run of a PVM program, users can select the group of machines; It is a message-passing model, Process-based computation; Supports heterogeneous architecture. Data Parallel Programming The major focus of data parallel programming model is on performing operatio...
A smooth curve γ⊂M is called a geodesic if its velocity vector is parallel along the curve: (4)∇γ.γ.=0. This means that the tangent, γ., does not turn with respect to itself along the path, i.e., γ is a straight path with respect to the Riemannian metric. Indeed, ...
