These images clearly indicate an improvement in quality by a reduction in the occurrence of large cracks in the through and rib sections of the casting, comparing injection profile B (Figs. 3b & 3d) to injection profile A (Figs. 3a & 3c).
Modelling and simulation of die filling would be useful but the lack of shear rate dependence on temperature data of semi-solid Al-Zn-Mg-Cu precludes its usefulness.

Statistical analysis of quantitative data to ± s, the number of groups were compared by analysis of variance, comparison of rates with chi-square test.
Because metabolic syndrome is not exactly the same as a single disease such as diabetes, while in the presence of multiple risk factors, should be integrated application of antihypertensive, lipid-lowering, hypoglycemic, and weight reduction programs.

Rotter type A has its greatest reduction to the carrying capacity of the cylinders.
Meanwhile, the measured data is close to halfway between Rotter type A and B [6].

However, only a few data of the oxidation behavior of the conventional Co-Cr alloy is available.
In contrast with former published results [8], the maximum reduction didn’t achieve because the Cr content content was not enough to support the growth of a dense, stable Cr2O3 layer.

At present these resources are most used for refractory raw material, but the records which short mullite fibers are manufactured by the andalusite mineral resources have not been seen in the literature data.
The value of interplanar spacing lessens with reduction of lattice parameter [7], in other words, the lattice parameter of mullite is the smallest under 1450˚C.

Multi-pulse converter (MPR) is one of the most powerful tools for harmonic reduction because of is robustness, efficiency, and simplicity in control [4~6].

Because of the excursion of fractal parameters (see chapter III) caused by the difference of SNR (signal to noise ratio) of input signals, the classifier trained by the data obtained through PD experiment in laboratory, only applies at some certain noise level.
And the excellent performance of the fractal theory in feature reduction makes it widespread used in pattern recognition.

Introduction Die casting industry has developed rapidly in China in recent decades, castings are widely employed in aviation industry, machinery industry and other domain. especially in the automotive industry, 65%~75% of the total die casting is used in the automotive industry , this data is upto 80%~90%[1] in America and Japan. die casting industry development match the requirements of energy conservation and emissions reduction. conversely, to achieve this goal further, Automobile lightweight technology represents high standards about design and manufacturing of parts. this paper carried out the numerical simulation study for crankcase based on AnyCasting, adopting process of local extrusion for structure weakness after Die Casting Forming so that obtain high-quality die castings.

Depth image data acquired by Kinect It needs to collect a great number of human posture images for training to recognize and test the common postures.
From the research status of the depth image in the pattern recognition and application in the human recognition, combining with the Kinect camera and imaging principle and the performance reduction of visible light under illumination, posture, shielding and the like, a method for distinguishing the human parts and postures by the local gradient characteristic combining the comprehensive point characteristic and the gradient characteristic is suggested.

Atherosclerosis is a progressive chronic inflammatory disease which can be haracterised by a gradual thickening and hardening of arteries that ultimately leads to a reduction in the lumen diameter and potentially to ischemia.
These data are in agreement with the model which has two short intracellular segments (residues 1-6 and 461-471) and two transmembrane domains (residues 7-28 and 439-460).
