Challenges and Potentials of Assembly Process Data in Flexible Order Production
Fig. 3 shows selected manufacturing organizations and the resulting material stream.
For an entire assembly process, every data set has to be linked to another via specific key attributes.
The extraction and data linkage is performed by individual queries and regular expressions in combination with general key attributes.

The aim of this article is to explore state of art discussion of various techniques and materials involve in cell encapsulations.
Materials in Cell Encapsulation The materials used in cell encapsulation must be of constant quality and be biocompatible with the host and the enclosed cells.
A number of alginate composite materials have also been explored for cell encapsulation [118].

Abstract.
Schmid [9] defined the multiferroics as single phase materials which simultaneously possess two or more primary ferroic properties.
It should be noted here that in many reports on various orthorhombic materials, the T3/2 and T2 magnetic terms were not resolved [58, 62].
Room temperature as well as temperature dependent Raman spectra for RMn2O5 family of materials have been reported by various groups [44, 64].

The key to the patent was addition of a small amount of bismuth oxide which resulted in very attractive slag detachment.
However, the first constitution diagrams, beginning with that developed by Strauss and Maurer [2] in 1920, were developed for wrought materials, not weld metals.
Schaeffler [5] in 1947 developed the first constitution diagram for weld metal based on the modified Strauss and Maurer Diagram for wrought materials and the chromium and nickel equivalents that had evolved to date.
This was an important contribution providing guidance to the welding engineer in filler metal selection for a host of dissimilar metal joints.

Keywords: semisolid, near-eutectic, ADC12 alloy, rheo-diecasting
Abstract
It is demonstrated experimentally that by using the mechanical rotational barrel processing system combined with high pressure die casting machine, the near-eutectic ADC12 alloy is possible to be rheo-processed.
Introduction Developed from the study on the behaviors of alloys in the semisolid state pioneered by Spencer et al. [1], it has been well recognized that semisolid processing (SSP) exhibits significant advantages over the traditional material processing techniques, such as good net shape capability, low energy cost, less entrapped air, fine grain size, porosity and segregation [2, 3].

Keywords: Brushless Doubly Fed Machine, magnetic field moudation, rotor stucture, pole numbers
Abstract.
Common salient pole reluctance rotor is composed of iron magnetic material (Fig. 2(a)), which completes rotor magnetic field modulation for two stator windings by producing harmonic field for magnetic field asymmetrical distribution.
Conclusion At present, BDFM has not been used in industrial and agricultural production, the key reason for having not rotor with higher magnetic field modulation effect.
