Deformable or snake models are extensively used for medical image segmentation, particularly to locate tumor boundaries in brain tumor MRI images. Problems associated with initialization and poor convergence to boundary concavities, however, has limited t... see more

Image segmentation is regarded as the most crucial medical imaging process because it extracts the region of interest and thus helps upgrade medical diagnosis. The Geodesic deformable model is a curve that deforms within digital images to extract object s... see more

Semi-infinite targets of Ultra-High-Performance Fibre-Reinforced Concrete with various fibre volume fractions were subjected to the high-velocity projectile impact using in-service bullets. In this study, a variety of empirical and semi-analytical models ... see more

This paper presents a newly developed aero-servo-elastic platform for implementing smart rotor control and shows its effectiveness with aerodynamic loads on large-scale offshore wind turbines. The platform was built by improving the FAST/Aerodyn codes wit... see more

The dynamic process of an underwater explosion (UNDEX) bubble in the vicinity of deformable structures is a complex phenomenon that has been studied by many researchers. The dynamic process of a UNDEX bubble is a complex transient problem that results in ... see more

This paper presents a dimensionless model for the depth of penetration (DOP) of a projectile penetrating into a concrete target, based on the similarity theory involving intermediate asymptotics, complete similarity, and incomplete similarity. The calcula... see more

NUMERICAL SIMULATION PLAYS A CRUCIAL ROLE IN TODAY’S AVIATION INDUSTRY. MODERN COMPUTERS WITH THE LATEST COMMERCIAL FE CODES HAVE FUELED THE TRIUMPH OF ESTABLISHING SIMULATION AS A PREREQUISITE OF AEROSTRUCTURE PART DESIGN FROM MICRO MODELING OF MATERIALS... see more

Nowadays, explosive processes are widely used for the optimization of extraction minerals processes, in the buildings construction and industry. This practice allows to significantly increase the speed of the work and, at the same time, reduce it cost. Ho... see more

A model for the impact between a structurally deformable sphere and a rigid flat surface is presented. It includes a nonlinear contact element that accounts for energy loss due to local plastic deformation or flattening of the sphere, a viscous element th... see more
