چکیده

0' ABSTRACT Ten volunteers were exposed to high intensity double pulse light flashes with flash fields subtending l-, 3?, 50, 10P, and 15q of visual angle. Flashblindness recovery times for several aircraft instruments were measured for each flash field diameter, Countermeasures including looking around the afterimage and body movement were permitted on some of the trials. Recovery time increased as the adapting flash visual angle was increased from 10 to 15!. Instruments requiring a greater visual acuity, to be read had substantially longer recovery times than instruments requiring less. The two countermeasures 'listed above were found' to be helpful in reducing recovery time.

The effect of composition on flash sintering parameters of varistors based on ZBS

Flash sintering is one of the latest sintering processes of ceramics, which has recently attracted the attention of researchers due to its high sintering speed and significant energy reduction. An essential feature of successful flash is negative temperature coefficient (NTC) semiconductor behavior. In this research, the flash sinter process of ceramic varistor based on ZnO-Bi2O3-Sb2O3 (ZBS) ha...

A General View on Hardware of Full Fligh Simulator

A simulation is an imitation of some real thing, state of affairs, or process. To simulate something physical, you will first need to create a mathematical model which represents that physical object. Simulation of a system can be done at many different levels of fidelity so that whereas one reader will think of physics-based models and output, another may think of more abstract models which yi...

Effect of Current Density, Temperature, and Contact Paste on Flash Sintered 8YSZ

Flash sintering has been investigated as a modern sintering method through examining the effect of processing parameters such as current density, temperature, and contact paste on the flash sintered 8YSZ characteristic. 95% of theoretical density was achieved at 800°С in 30sec with a field intensity of 100V.cm-1 and a current density of 160mA.mm-2. Such relative density in conventional sinterin...
