this study investigates the prediction model of compressive strength of self–compacting concrete (scc) by utilizing soft computing techniques. the techniques consist of adaptive neuro–based fuzzy inference system (anfis), artificial neural network (ann) and the hybrid of particle swarm optimization with passive congregation (psopc) and anfis called psopc–anfis. their performances are comparativ...

Isolated FePt particles were fabricated by taking advantage of overgrowth of Fe on Pt particles and subsequent annealing at 873K. The annealing lead to the formation of ordered tetragonal (L10) FePt particles with three orthogonal variants. The average size of FePt particles could be adjusted to less than 10 nm and no significant grain coarsening occurred upon annealing due to the existence of ...

Practical application of superhydrophobic surfaces is limited by the fragility of nanoscale asperities. Combining chemical etching and anodization, microscale pits and nanoscale pores, instead of the micro and nano protrusions on traditional superhydrophobic surfaces mimicking Lutos leaves, were fabricated on commercially pure aluminum surfaces. After modified by FDTS, the surfaces were superhy...

The global demand of the heating and cooling applications gives a larger potential to study thermal energy storage system. Phase change materials (PCM) that are used charge, store, discharge heat inferior in transfer characteristics. properties PCM can be improved by adding nanoparticles, changing orientation enclosure or both. Two-dimensional transient numerical analysis on effect Grashoff num...

•Several materials have been investigated for use in nano-CMOS technology, such as ZrO2, TiO2, BST, HfO2, Al2O3, SiON, and Si3N4. •Intel has recently prototyped a processor called Penryn using such transistors of 45nm technology. •For compact modeling based study of high-K non-classical transistors using BSIM4/5, two possible options can be considered: (i) varying the model parameter in the mod...
