New Nissan to feature complex aluminum castings The new Nissan GT-R features aluminum inner-door and rear-seat structures made from Alcoa’s proprietary vacuum die casting process (AVDC) at the company’s plant in Soest, Germany. Both components also feature new proprietary alloys developed by Alcoa. The new C-446 alloy, in combination with the unique advantages of the AVDC process, enabled Alcoa...
متن کاملExplaining complex metals with polymers.
Analogies and metaphors are widespread in science. We use them to convey difficult concepts to colleagues or when popularizing science to communicate with the general public. Analogies also form an integral part of the scientific process itself (1). Some may even say that science is all about finding analogies between seemingly different phenomena, organizing them using unifying abstract concep...

متن کاملThe surprisingly high human efficiency at learning to recognize faces
We investigated the ability of humans to optimize face recognition performance through rapid learning of individual relevant features. We created artificial faces with discriminating visual information heavily concentrated in single features (nose, eyes, chin or mouth). In each of 2500 learning blocks a feature was randomly selected and retained over the course of four trials, during which obse...
