A virtual viewpoint generation method is proposed to address the problem of low fidelity in viewpoints for images with overlapping pixel points. Virtual factors such as overlaps, holes, cracks, and artifacts are analyzed preprocessed. When background hole a simple texture, pheromone information around used support, at edge detected, predicted same time, so that area filled blocks. has relativel...

Multi site damage is one of the important aspects to be studied to ensure the safety of the aircraft structure. The rivet hole locations are one of the stress concentration regions. The current study includes a panel which represents the fuselage splice joint. The fuselage splice joint is a location where it experiences the uniform stress field at many rivet locations in a row. This study has r...

By a combination of geometrical and configurational analysis we study the properties of absolute minimal and equilibrium states of general Mumford-Shah functionals, with applications to models of quasistatic brittle fracture propagation. The main results concern the mathematical relations between physical quantities as energy release rate and energy concentration for 3D cracks with complex shap...

A new scheme for adaptive reenement of tetrahedra based on an edge criterion is presented. This scheme guarantees consistent subdivision without cracks without the necessity for checks between neighboring tetrahedra of a mesh, allowing a recursive algorithm with low space requirements and parallel implementation.

By applying a filter this algorithm can reduce the number of polygons generated by subdividing a mesh dynamically. This algorithm is designed especially for real-time engines where the geometrical complexity is critical. It also avoids edge cracks and is generally more efficient than a general-purpose polygon reduction algorithm.

Creating models of real objects is a complex task for which the use of traditional modeling techniques has proven to be difficult. To solve some of the problem encountered, laser rangefinders are frequently used to sample an object ́s surface from several viewpoints resulting in a set of range images that are registered and integrated into a final triangulated model. In practice, due to surface ...

The purpose of this research was to present a simulation modelling crack propagation trajectory in linear elastic material subjected mixed-mode loadings and investigate the effects existence hole geometrical thickness on fatigue growth life under constant amplitude loading. For various geometry thickness, (I/II) studies were carried out utilize single edge cracked plate with three holes compact...

The miniaturization and three dimensional die stacking in advanced microelectronic packages poses a big challenge to their non-destructive evaluation by acoustic micro imaging. In particular, their complicated structures and multiple interfaces make the interpretation of acoustic data even more difficult. A common phenomenon observed in acoustic micro imaging of microelectronic packages is the ...
