Introduction The rapid exhaustion of fossil resources and environmental concerns has significantly impacted the adoption of renewable feedstocks for the long-term progress of polymeric materials in recent decades.
On the other hand, the crosslinked functionalized oils cannot match the qualities of petroleum-based materials employed in industrial applications [8].

In a unique approach, we are also exploring flat surfaces of doped nanocrystalline diamond films that have been studied as candidate materials for field emitters.
Thus these flat surfaces have materials properties that lead to field enhanced emission from the nanoscale sites.
These materials could also be candidates for the thermionic emitters in an energy conversion system.
The experimental results have been analyzed with the Richardson expression to determine the materials related constants, A and φ.

In the other part of the paper, the influence of the welding process on the structural modifications and grains’ size in the heat affected zone (HAZ) of both base materials (BM) has been described.
Filler material deposition was also simulated.
HAZ width of a structural steel is the region heated from lower critical temperature (i.e. 996K) to the temperature just below the melting point temperature of welded materials (i.e. 1742K).

The key to the present optimization problem is to determine the relative contributions of solute Nb and Nb(C,N) precipitates to the retardation of static recovery and recrystallization.
At the other extreme, when the solute content is very low, or when the driving force is large, the alloy behavior approaches that of the pure material and a small increase in driving force results in a large increase in boundary velocity.

Architecture is indeed a highly integrated, and almost an all-inclusive set of practical, engineering and artistic as one of the disciplines.
The development of new technologies and new materials continues to emerge in contemporary context.
It involves its own objective status”(Eisenman,1978)We call it the autonomous realm of inquiry.[5] The concerns of the autonomous realm of inquiry are the building construction, materials, structure, and spatial modeling system.
Technological logical thinking corresponds to the construction, relates to the technology, materials, structures and devices.
For example, in late 1990s’ a variety of new materials and new technologies are applied to building skin.

The maximum not unusual place methods that humans have used to put in force diverse advice structures are the collaborative filtering, classification and primary content material models.
Additionally, those well-known and installed on-line carrier carriers use personalization as a key a part of their pointers, as generalization can't be greater correct with described parameters.
Learning Objective The learning objective of the music recommendation project was the first to become familiar with machine learning and its key concepts as well as the different data mining techniques and the algorithms [5].
Learning the algorithms on my own does not make you an engineer, the actual assignment is getting to know the which set of the rules is the proper one to use for a selected project.

The biogas is obtained from organic materials decomposition; mainly the methane has energetic potential, especially for the combustion process in internal combustion engines.
The development of this sector is confronted with its competition with the food processor in semi-arid countries like Algeria, which limits its potential to respond to national energy demands to the use of various waste materials in order to produce biofuels.
