As the Universe expands, redshift of distant sources changes with time. Here we discuss gravitational lensing phenomena that are consequence drift between lensed source, lens, and observer. When source is located very close to drifting caustics, a pair images could occur (or disappear) because cosmological expansion. Furthermore, systems act as signal converters drift. The angular position, mag...

plan irregularity causes local damages being concentrated in the irregular buildings. progressive collapse is also the collapse of a large portion or whole building due to the local damages in the structure. the effect of irregularity on the progressive collapse potential of the buildings is investigated in this study. this is carried out by progressive collapse evaluation of the asymmetric mid...

Modern detectors such as ATLAS use pressurized drift tubes to minimize diffusion and achieve high coordinate accuracy. However, the coordinate accuracy depends on the exact knowledge of converting measured times into coordinates. Linear spacetime relationships are best for reconstruction, but difficult to achieve in the E ∝ 1 r field. Previous mixtures, which contained methane or other organic ...
