Abstract A representative and most commonly used ballistic target system consisting of a 93W ball Q235 steel plate is investigated for its limit fast calculation engineering model. The basic data on the material projectile was obtained through quasi-static compression tests mechanical properties materials. Using Φ12.7mm gun ten shot v50 method, were carried out with balls positively penetrating...

conclusions despite the widespread use of 2d lvef and its good agreement with ventriculography, strain analysis seems to be more reliable as a quantitative tool for ventricular assessment. results the lvef values obtained by the two methods of ventriculography and echocardiography were not significantly different. the highest correlation regarding the echocardiographic lvef was obtained in the ...

In the semiconductor industry, hydrogen is used with many other hazardous and dangerous substances flammable, toxic, corrosive properties. order to safely handle them, convenient-to-use gas cabinets are often required. As known well, highly flammable explosive, risk analysis needs use in cabinets. this study, overpressure impact according various cabinet conditions were measured when leaks cabi...

As a generalization of the 2D Fourier transform (2D FT) and 2D fractional Fourier transform, the 2D nonseparable linear canonical transform (2D NsLCT) is useful in optics and signal and image processing. To reduce the digital implementation complexity of the 2D NsLCT, some previous works decomposed the 2D NsLCT into several low-complexity operations, including 2D FT, 2D chirp multiplication (2D...

We describe a case of abrupt cardiac arrest in an 80 year old woman. Emergent transoesophageal echocardiography (TOE) helped clarify the diagnosis of pulmonary embolism, and guide management and ongoing resuscitation. This case highlights the utility of TOE in the peri-arrest setting and in the diagnosis of massive pulmonary embolism. TOE can also be useful in providing prognostic information a...
