Since material is subjected to shear and friction action between the screw and the sleeve, as well as between the material and the material, so large amounts of heat is produced that the water in the materials is transformed into overheat water steam in a very short time, and in the compression chamber the high pressure is formed.
During the process of screw rotationally promoting materials, the force is large on the pressure surface of the helix, and the force is small on the non-pressure surface, so the load mainly was applied on the pressure surface.
According to the relation curve between materials compression ratio and pressure in the extrusion chamber, we applied load on the sleeve and the nozzle.

Introduction Self-Organizing Maps have been used in many science areas: as a tool for organizing large amounts of data, as a tool of speech recognition differing between several groups of people, for process monitoring in engineering and natural science, and for classification of data in different fields like finance and social science.
Piezoelectric materials are used as sensors and actuators for the generation and measurement of ultrasonic waves for inspection of structures and involve many advantages like applicability for high frequencies as well as being able to cope with only a small amount of energy.

Introduction Nowadays explosive welding is one of the most widely used technologies for the production of composites from various pairs of materials.
Depending on solubility of elements into each other materials can be classified as materials forming intermetallics, materials are completely soluble into each other and materials with no mutual solubility.
In many of studies [3-11] it was noted that during welding of dissimilar materials, an intermetallics thin layer was formed at the interface.
In this case the size of new grains originated at the most intensively deformed regions of materials is 6 µm.

Some kinds of resources can be employed over the internet without actual materials transport, but there are still some kinds of resources must be employed with materials logistics.
In most cases, several unparalleled sub-tasks are assigned to several individual virtual resources, and the materials need to be transported among several individuals, so a full consideration of the impact of logistics costs must be taken. 2.
