NUMERICAL INVESTIGATION OF THE BEHAVIOUR OF BOLTED AND WELDED TOP AND SEAT ANGLE CONNECTION IN PROGRESSIVE COLLAPSE OF STEEL STRUCTURES

Numerical investigation of the behaviour of bolted and welded top and seat angle connection in progressive collapse of steel structures

After failure of a column in structure by an abnormal loading, undesirable performance and damage of connections of the beams connected to the top of this column, can lead to the local failure of floor and in turn result in progressive collapse in the structure.Accordingly, the best method for rehabilitation of the structure against this incident i

Direct nonlinear acceleration

Optimization acceleration techniques such as momentum play a key role in state-of-the-art machine learning algorithms.Recently, generic vector sequence extrapolation techniques, such as regularized nonlinear acceleration (RNA) of Scieur et al.[22], were proposed and shown to VITAMIN E CREAM accelerate fixed point iterations.In contrast to RNA which

Optical and MRI Multimodal Tracing of Stem Cells In Vivo

Stem cell therapy has shown great clinical potential in oncology, injury, inflammation, and cardiovascular disease.However, due to the technical limitations of the in vivo visualization of transplanted stem cells, the therapeutic mechanisms and biosafety of stem cells in vivo are poorly defined, which limits the speed of Napkin Set clinical transla
