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.

Carbon fiber, because of its superior features like strong mechanical strength, elasticity, low density, and excellent fire resistance, is widely used as reinforcement materials [5].
Jute fiber is a natural fiber which is used to manufacture composite materials by many researchers throughout the world from the last few years.
Experimental Procedure and Methodology Materials and specimen preparation: Carbon fiber (T 700, unidirectional, 300 GSM) and jute fiber (unidirectional, 504 GSM) were used as the core of the composite material.

Shrinkage performance test of Semi-rigid base material does not have uniform standard In our country[6] .Through the analysis of of all kinds of test method combined with the actual conditions of the laboratory.In this article,we use bracket method when we do the dry shrink test on Cement stabilized gravel base materials;and we use Strain gauge measurement when we do temperature shrinkage test on Cement stabilized gravel base materials[7].
So, we can see that, cement stabilized gravel materials of dry shrink is lagging, and it also showed that the decrease of the early loss rate will inhibit dry shrink.
Every 1% increase on cement dose, and average dry shrinkcoefficient of materials increase 35×10-6 / % or so.
(3) Cement stabilized gravel materials of dry shrink is hysteretic.

Material structures from nature could be an inspiration to optimize the DRC coatings.
Some bio-inspired material structures for radiative cooling are developed as well.
These distributed Bragg stacks are formed from similar materials, but with layers of different effective refractive indices.

RP system integrates mechanical manufacturing, CAD, laser technology, and material science technology.
As the material used by RP system to produce work piece differs from the industrial material in actual manufacturing, it cannot be reckoned as manufacturing equipment.
During the process of modeling, the temperature of molten material has to be kept around the melting point in order for the layers of molten material to adhere properly and harden instantly.
