Human observers easily recognize complex natural phenomena, such as flowing water, which often generate highly chaotic dynamic arrays of light on the retina. It has not been clarified how the visual system discerns the source of a fluid flow. Here we show that the magnitude of image deformation caused by light refraction is a critical factor for the visual system to determine the perceptual cat...

A widely used method for hot forming steels and alloys, especially heavy forging, is the process of multistage forging with pauses between stages. The well-known effect which accompanies multistage hot forging is metal plasticity recovery in comparison with monotonic deformation. A method which takes into consideration the recovery of plasticity in pauses between hot deformations of a billet un...

abstract: mustard is a natural multi-functional additive with strong hot flavor. in this research, powdered yellow mustard (sinapis alba) was heated by 21 different thermal processes, statistically designed by response surface methodology to evaluate the effects of combinations of heating media (hot air, hot water and steam) and heating time (0-20 min) on residual myrosinase activity, the minim...

Among the titanium alloys, Ti-6Al-4V is the most widely used. In the present work, the uniaxial hot compressive behavior of Ti-6Al-4V has been investigated under constant strain rates. A series of dilatometery experiments were carried out to determine the transformation temperatures at different cooling rates. Specimens were homogenized at 1050 °C for 10 minutes followed by fast cooling to dif...

Exotic-deformation effects in 46 Ti nucleus were investigated by analysing the high-energy γ-ray and the α-particle energy spectra. One of the experiments was performed using the charged-particle multi-detector array ICARE together with a large volume (4 " ×4 ") BGO detector. The study focused on simultaneous measurement of light charged particles and γ-rays in coincidence with the evaporation ...

The large deformation effects in the light-mass nuclei have been studied over last years, using both gamma and charged-particle spectroscopy. In particular the very elongated prolate or triaxial shapes were observed from the spectra of the Giant Dipole Resonance (GDR) decay for 46Ti* [1] and 45Sc* [2]. The results were consistent with the predictions of the LSD (LublinStrasbourg Drop) model [3,...

Titanium alloys exhibit high specific strength and stiffness that fit structural applications demanding lightweight. The microstructure of the alpha-beta titanium alloys can be changed by thermomechanical processes such as heat treatments and pre-forging to achieve a certain ductility. Ceramic reinforcements can improve specific strength and stiffness, and also the wear resistance. In Situ part...

In this paper, properties of slab deformation in sizing press mill as one of the slab reduction processes in hot rolling mills have been evaluated using the elastoviscoplastic finite element method with explicit formulation. Effect of prarameters such as initial slab width and thickness, reduction, feed pitch, and anvil speed on factors such as dogbone formation, head and tail fishtail profile,...
