Upon cooling, instead of direct expansion from ES1 to an equilibrium shape 2 (ES2), the gel (ES1) folds into tighter zig-zags and then unfolds to ES2 (Supplementary Movie 1). For hydrogels with higher PVA content, the swelling ratio undergoes a more remarkable decrease. , and T. For articles published under an open access Creative Common CC ...

Be careful not to remove any ofthese items from this folder. You’ve seen plenty of work done by EI artists on broadcast television and featurefilms. Radiocity is a special program that calculates how light and color bounces fromsurface to surface in a very realistic way. 3D animation always impresses and captivates an audience and IR...

Half of the specimens were tested at room temperature to determine punching shear strength. 75 vRd,c + 1. The slab was concreted on layer-compacted gravel with a thickness of 0. u = the length if the basic control perimeterThere are numerous design techniques to mitigate against punching shear. The punching resistance of column bases should ...

. Using this model, it was possible to assess the contribution of each input variable to the compressive strength of the tested concretes. The results indicate an excellent performance of the ANN model developed to predict compressive strength from the input parameters studied, with an average error less than 5%. Several artificial neural n...

The registered experimental results have been compared to the ultimate loads intended by Eurocode 3 for empty columns and by Eurocode 4 for compound columns. LE / ry = 138. 646 x 2175 x 103 x 10-6 = 253. On the other hand, by comparing the results between the square and rectangular cross-sections, it can be found out that eliminating the symm...
