As verified by literature, heat-treatments of as-atomized Al-alloy powders before cold spraying, result in microstructural homogenization and deposition efficiency increment. So far, a straightforward correlation between powder strength consequences for the performance spraying deposit properties is still missing. This work thus provides reliable analyses strengths annealed states to calculatio...

Abstract Turbines are core components in jet engines for flight propulsion, power plants, and other important energy conversion processes. They composed of successive rows blades so that wakes upstream reach subsequent where they perturb the flow an unsteady manner. At point a wake reaches downstream blades, perturbation forms so-called negative jet. In this work, we show partially fulfills con...

This paper presents a novel hierarchical shape segmentation method based on splats for 3D shapes. The major contribution is to propose a new similarity metric based on splats, which combines patch-aware similarity and part-aware similarity adaptively. An optimized L metric for VSA (variational shape approximation) method is used to get splats first, and such adaptive similarity metric is used t...

This paper presents a system for self-plagiarism detection, SPLAT. The system uses a WebL web spider that crawls through the web sites of the top fifty Computer Science departments, downloading research papers and grouping them by author. Next a text-comparison algorithm is used to search for instances of textual reuse. Instances of potential selfplagiarism for each author are reported in an HT...

An overview will be given of some recent results of microstructural electron microscopy studies on martensitic systems. The precursor structure observed in a ternary Ni-Mn-Ti alloy and its correlation with the ensuing stacking sequence is presented. New types of materials of a well known alloy, in casu splat-cooled and nanoscale thin films of Ni-A1 are investigated revealing particular morpholo...

The thermal cyclic behavior of self-healing barrier coatings (SH-TBC) is analyzed numerically to develop a lifetime prediction model. Representative microstructures are studied adopting unit cell based multiscale modeling approach along with simplified evolution model for the thermally-grown oxide layer (TGO) study damage and healing in TBC system. fracture process modeled using cohesive zone-b...
