In-plane compression of constrained preforms

Data Compression of Cutting Plane

We propose an efficient algorithm for compressing cutting plane of three dimensional Computational Fluid Dynamics (CFD) data set. Observing the cutting planes of large 3D CFD data set is an important method for examination of simulation result, and efficient compression algorithm of these cutting planes is important for good performance of visualization when the simulation is running in a remot...

Constrained Pursuit - Evasion Problems in the Plane

In pursuit-evasion problems, we are presented with one or more pursuers attempting to capture one or more evaders. We consider pursuers and evaders limited by a maximum speed moving in the two-dimensional plane with obstacles. We then investigate two problems in this domain. In the first, where we are given the starting configuration of pursuers and evaders, we identify all possible paths by th...

Maximum face-constrained coloring of plane graphs

Smoothness-constrained wavelet image compression

The uniform quantizers used in typical wavelet image compression algorithms can introduce perceptually disturbing artifacts by decreasing visual smoothness. In this paper, we use local Hölder regularity to quantify changes in visual smoothness and propose a modified quantization scheme which constrains local regularity decreases. The reconstructed images show a significant perceptual improvemen...

Buckling Behavior of Composite Plates with a Pre-central Circular Delamination Defect under in-Plane Uniaxial Compression

Delamination is one of the most common failure modes in composite structures. In the case of in-plane compressional loading, delamination of a layered flat structure can cause a local buckling in delaminated area which subsequently affects the overall stiffness of the initial structure. This leads to an early failure of the overall structure. Moreover, with an increase in load, the delaminated ...
