The buckling failure of the afterburner cylinder is a serious safety concern for aero-engines.To tackle this issue, the buckling simulation analysis of the afterburner cylinder was carried out by using finite element method (FEM) software to obtain the buckling mode and critical buckling loads.It was found that the afterburner cylinder was suscepti
The continued development of intraocular lens (IOL) technology has led to a dramatic improvement in refractive outcomes.New and innovative ways of achieving the desired postoperative refractive goals continue to be developed.This article aims to review the currently available IOL modalities for correction of presbyopia at the time of cataract surge
If territory is part of the problem in the quest for peaceful relations, it should also be part of the solution.This is the core argument in the present text, where the work of international lawyer Louis Sohn during Baseball the Cold War and efforts towards territorial disarmament across time and space are used as starting points for the exploratio
Questions of the quality of computer-based models and the formal processes of model testing, involving internal verification and external validation, are usually given only passing attention in engineering reports and in technical publications.However, such models frequently provide a basis for analysis methods, design calculations or real-time dec
The graphene based metal-insulator-metal (MIM) metamaterial is numerically investigated to realize an active and adjustable multi-band perfect absorber, which is composed of an asymmetric double T-shaped cavity on the top layer.As the symmetry of T-shaped cavities is broken, the previous dual-band absorption will be converted to tri-band absorber.T
