It was extended to considering thermal effects by Nowacki [4,5], and Eringen [6] et al.
Recently, Kumar [9],Deswal[10],Othman et al.[11,16],El-Karamany[12],Singh[13,15,17],Song,et al.[14], Kumar and Sharma[18,19] have studied various problems on wave propagation at interface between different half-spaces with microstructure by micropolar elasticity theory, micropolar generalized thermoelasticity theory or micropolar generalized thermoviscoelasticity theory.
It coincides with the results of Ewing et al.[20] for elastic case.

El Faouzi, Lesort [1] and Sethi and et al. [2] presented that an actual traffic and transport problem can be positioned as a data fusion problem in their early papers, and the information fusion technology had become a reality with the development of Intelligent Transportation System (ITS) as the representative of intelligent and systematic applications in the field of transportation.

The mechanical properties of the PFRP material were provided by Boonsuan et al. [4].
Five tensile coupons cut from the test specimens were tested in accordance with ASTM D3039, in order to determine EL.
From the coupon test, it was found that the average values of EL and GLT were 35.20 GPa and 2.18 GPa, respectively.
Since the PFRP material is usually considered as orthotropic and homogeneous material, characterized by two independent elastic constants: the longitudinal tensile modulus of elasticity (EL) and in-plane shear modulus (GLT).
Also, the orthotropic effect of the material with EL/GLT ratio of 16.1 does not play an important role on the critical buckling moment of the beam.

The scheme proposed by Ortega et al was shown to perform adequate for the torque control problem but when applied to the speed tracking problem, it requires the very rigid assumption that the load torque is a known smooth and bounded function with known bounded first derivative [4].
PBC can be applied to systems described by Euler-Lagrange(EL) equations, so consider the DFIG model(1) and (2) described by the EL equations of motion (3) where ,,, ,, , ,, , ,,.
In the DFIG model EL equations(3), the first term in the left side is the control force, the third term in the right side is the dissipative force, and the second term in the right side is the configurable ‘workless forces’, in which is skew-symmetric and satisfied
It can be concluded that the workless forces , which appear in the EL equations of the DFIG, have no effect on the energy balance function.
Conclusion Based on the analysis of EL system model of the DFIG in wind power systems, a PBC method for solving the output feedback global tracking problem is developed.

Recent work of El Mrabet et al. classified tribological behavior of the magnetron sputtered W-C coatings co-doped with carbon into three regions: adhesive wear region when COF >0.8 and C content is low, intermediate behavior characterized by an abrasive wear (COF = 0.3-0.6) and self/lubricated wear for COF< 0.2 and excess of free carbon [9].
Thus, no obvious correlation was observed among COF, nanohardness and wear behavior despite direct correlation is assumed from the analysis of El Mrabet [9].

Two different types of substitution were considered: (1) Al substitutes for Ti, and (2) Al substitutes for N.
In order to conclude which sites may be occupied by small amount of Al in TiN with NaCl structure one of Ti or N atoms in the expanded cubic supercell was substituted by Al.
The obtained energies allow us to determine the site occupied by Al atoms in Ti-Al-N.

CeO2 Ce1−X 4+ CeX 3+ O2−X/2VoX/2+X/4 O2 (Vo: oxygen defect, 0al. [9] suggested that the evolution of oxygen from ceria would be depressed by doping with metal ion possessing larger ionic size to stabilize fluorite structure and/or lower valence metal ion to shift the equilibrium of Eq. (1) to the left hand side by forming oxygen defect.
