Therefore, it showed that the hybrid natural Luffa/GCW FRP has the potential in the engineering industry, such as lightweight furniture, household appliances, automotive parts, and other composite engineering applications.
Current research suggests that GCW has tremendous promise in a wide range of composite engineering applications, including automotive, packaging, and lightweight furniture [15].
The outcome of present work shows that this composite has the potential in many composite engineering applications, such as automotive, packaging, and lightweight furniture.

The issues of measurement in terms of engineering are based on a scientific discipline called metrology [10].
However, this can be difficult because the innovative environment is not prepared to absorb advanced innovative technologies.
The condition can be stable, resulting from the features of the manufactured goods that are assumed not to require advanced research.

Residual strains were calculated using: ε = (a - ao) / ao, where a is the lattice spacing measured across the centerline and ao is the "stress-free" lattice spacing measured at 60 mm away (on the advancing side) from the centerline for each scan setup.

Recently, this topic has received a considerable interest, because of the excellent thermal performances and the various benefits, of nanofluids, in several engineering applications such as microfluidics, microelectronics, pharmaceutical processes, etc.
In chemical engineering and geosciences fields where heat and mass transfer occur simultaneously in a binary fluid, the cross-diffusion effect caused by the coupling between the thermal and solute gradients is very significant.

Yunhui Yang Associate Professor of Construction Engineering Department, Kunming Metallurgy College,Kunming, 650033, China Keywords:Green building, Rating System, Development Abstract.China has the biggest building construction market in the world today and it is growing at an explosive rate.
So far, Chinese government invested heavily in the construction of the demonstration projects, as all the additional cost of green buildings is usually borne by Chinese government funding awarded to demonstration projects, such as the Office Building of Green Building Engineering Research Center of Shanghai in 2004, and Shanghai historic protection building Wenyuan Building in Tongji University in 2007.15 In 2008, the State Council put forward to organize the implementation of 30 energy-efficient green building demonstration projects.
China also lacks green building technology and knowhow, namely, lack of expertise of integrated sustainable building design and construction among engineers, designers and constructors.
