INVESTIGATION INTO STRESS WAVE PROPAGATION IN METAL FOAMS

Investigation into stress wave propagation in metal foams

The aim of this study is to investigate stress wave propagation in metal foams under high-speed impact loading.Three-dimensional SUBLIME CURL CURL RITUAL CREAM Voronoi model is established to represent real closed-cell foam.Based on the one-dimensional stress wave theory and Voronoi model, a numerical model is developed to calculate the velocity of

Paradoxical thinning of the retinal nerve fiber layer after reversal of cupping: A case report of primary infantile glaucoma

The circumpapillary retinal nerve fiber layer (RNFL) thickness was assessed by spectral domain optical coherent tomography (SD-OCT) before and after surgical reduction of Bowls intraocular pressure in an eye with primary infantile glaucoma.In this case, a postoperative reduction of cupping and a subsequent increase in neuroretinal rim area is assoc

Improving the circuitry of high-precision high-speed acousto-optic laser interferometers of displacements with frequency matching of component blocks and double heterodyning at phototransformation stage

The article discusses the development of the circuitry of acousto-optic (AO) laser displacement interferometers (LDI) and the values of resolution and speed of controlled displacements achieved by them.The issues of frequency matching of blocks of AO LDI are discussed: AO modulator, photodetector device (FDD) and frequency generator.The features of
