Each of the process requires inputs such as energy and raw materials, and outputs such as products and emissions.
However, such methodology may not be applicable for Philippine scenario due to its unique raw material supply-chain and its environmental constraints.

The development of functional materials PEM has been focused a lot on organic-inorganic hybrid materials that blend the properties of the two components [17].
Biopolymer matrixes are often filled with inorganic materials as support.
Materials studies on polymer electrolytes membrane including filler usually utilize heteropoly acid or inorganic material with highly delocalized electrons in the anion.

Introduction
High hardness and high strength cutting materials, such as hardened steel, have become an important research topic in industry and academia.
One type of cutting tool suitable for difficult materials is ceramic cutting tool.
Yi et al [21] prepared self-lubricating ceramic materials with nano-calcium fluoride (CaF2) as solid lubricant by vacuum hot pressing process.
Workpiece material.

The singularity may result in anomalous amount of energy release or material accumulation within a narrow spatial-temporal interval.
A high gravity value indicates the presence of geological objects with higher average density than the materials surrounding them.

An analytic solution could be got by this method, and the physical meaning is clear, but the compression strain in collision is not considered, therefore, the material behavior and geometric changes cannot be represented accurately.
Zhu Ping etc. took material overlap into account and developed a 3D contact-friction collision model on the base of the contact theory of point to surface [9].
The friction coefficient between concrete materials was selected as 0.5.

For example, in Table 1 consider the potential levels for the first item “Intelligent Materials”, which varies from one (passive material) to four (totally adaptable material), four being the maximum potential for this trend.
Case Study Currently, optical fiber products have small dimensions (160x130x55mm) and some are manufactured with thermoplastic materials, which have a lower cost when compared to metallic materials.
To understand the data shown in Table 2, consider that for the first TE – “intelligent materials”, the product received a grade equivalent to 1/4.
This means that it was classified as a “passive material”, that is, grade one, considering that the maximum potential would be four if it was classified as “totally adaptable material”.
