Aeroelastic two-dimensional wing section with both trailing-edge (TE) and leading-edge (LE) was investigated in this paper through numerical simulation in time domain. Structural stiffness and damping in pitch degree of freedom were represented by nonlinear polynomials. Open-loop limit cycle oscillation (LCO) characters of two examples were studied, and flutter boundaries with initial condition...

The stability against crystallization of the amorphous phase‐change materials (CGT) exhibits an unusual behavior at low Cu concentrations with being most stable composition. Three CGT compositions , 15, and 25 are analyzed using extended X‐ray absorption fine structure (EXAFS) Ge‐K, Cu‐K, Te‐K edge 10 K. EXAFS analysis shows that average coordination number (CN) increases concentration from 2.8...

We are investigating the fusion of edge information into Markov Random Fields (MRF) region growing based image segmentation. Our goal is to segment the image in a way that would take edge information into consideration. This is achieved by modifying the energy minimization process so that it would penalize merging regions that have real edges in the boundary between them. Experimental results c...

We address the problem of detecting characteristic patterns in highly dynamic information networks (e.g., a retweet graph). We introduce a scalable approach based on set-system discrepancy. By implicitly labeling each network-edge with the sequence of times in which its two endpoints connect, we view an entire information network as a set-system. This view allows us to use combinatorial discrep...

Bermudagrass [Cynodon dactylon (L.) Pers.] is a perennial grass and has been long used as a medicinal herb in Iranian traditional medicine to treat varied ailments. Different parts of bermudagrass such as leaves, stolons, rhizomes and culms are rich sources of metabolites such as proteins, carbohydrates, mineral constituents, β-sitosterol, flavonoids, alkaloids, glycosides and triterpenoides. G...

The technique of counting cliques in networks is a natural problem. In this paper, we develop certain results on counting of triangles for the total graph of the Mycielski graph or central graph of star as well as completegraph families. Moreover, we discuss the upper bounds for the number of triangles in the Mycielski and other well known transformations of graphs. Finally, it is shown that th...
