Making Casts in Gelatin Molds

AIR PRESSURE SIMULATION IN CASTING MOLDS

During mold filling, molten metal can only advance as quickly as the air inside thecavity is expelled. In this work an analytical model describing air flow is developed based on aincompressible flow theory. Air pressure has serious effects upon the filling behaviour such assurface profile and filling time. In this work a new mathematical model is proposed for calculationthe air pressure during ...

Coping with Type Casts in

The use of type casts is pervasive in C. Although casts provide great exibility in writing code, their use obscures the meaning of a piece of code, and can present obstacles during maintenance. Casts involving pointers to structures (C structs) are particularly problematic, because by using them, a programmer can interpret any memory region to be of any desired type, thereby compromising C's al...

Analysis of Arterial Casts

In the region from arterial trunks to pial arterioles anatomical characteristics of the cerebral artery as revealed by quantitative treatment of the arterial cast consist in the predominance of the length of large arterial branches over that of the arterioles. Theoretical analysis of blood pressure drop based on the above result demonstrates a large pressure drop in the region of large arterial...
