Sm(CobalFe0.1CuxZr0.03)7 (x = 0.0–0.25) ribbons have been prepared by melt spinning. The effects of annealing parameters on coercivity and its temperature dependence have been studied systematically. It is found that the melt-spinning technique remarkably improves the magnetic properties and simplifies the annealing process. The high-performance precipitation-hardened magnets can be obtained by...

We developed a new method for deriving the onset date, end date, duration and spatial extent of snowmelt using satellite passive microwave measurements. Our method exploits the fact that apparent edges are present on the brightness temperature (Tb) time series curve corresponding to sharp and abrupt meltinduced transitions of brightness temperature. Through a wavelet transform of daily Tb obser...

Modelling and simulation of injection moulding process is an important technique that could shorten production cycle time with improved productivity for defect-free parts. This technique is more suitable for micro-injection moulding (μIM) process as likely defects during production can be predicted. Therefore, this study aims to investigate the effect of runner dimensions on quality of moulded ...

ÐA novel mesoscopic modeling technique has been developed to simulate the unsteady growth of multiple equiaxed dendritic grains into a supercooled melt of a pure substance. In the model, the numerical calculation of the temperature ®eld in the supercooled melt between the grains is coupled with a stagnant®lm model for dendrite tip growth, such that without resolving individual dendrite arms the...

Composition, mean pressure, mean melt fraction, and crustal thickINTRODUCTION ness of model mid-ocean ridge basalts (MORBs) are calculated Comparison of observed basalt compositions with the using MELTS. Polybaric, isentropic batch and fractional melts predictions of polybaric mantle melting models places from ranges in source composition, potential temperature, and final important restrictions...
