Singh et al. [4] described a case study to analyse the material removal rate (MRR) by the cryogenically treated zinc covered metal and cryogenic treated plain metal wire anodes.
Dhoe et al. [13] showed the effect of process parameter and effect of heat treatment on surface roughness of tool steel AISI D2 cut with CuZn37 master brass wire having 0.25mm diameter having tensile strength 900N/mm2 and De-ionized water (Ph value 12.5) was used as dielectric medium in WEDM with various input process parameters pulse on time(105-125units), pulse off time(40-60units), servo voltage (15-45 volt) and peak current (70-110 units) to minimized the surface roughness.

The works of Mustapha and al [4] are geared towards optimizing the effect of imperfect preventive maintenance actions on a redundant system.
While Maryam and al [5] dealt with the problem of optimizing maintenance by applying routine preventive maintenance interventions.
D and al [6] worked on the periodic planning of the three actions (simple service, preventive repair and replacement), the choice of the action to be applied is closely linked to the results of the inspections.
The study of the efficiency of the system in relation to the expected cost of the life cycle has been improved by Pascual and al [7], by proposing a maintenance model dedicated to production systems protected against demand fluctuations and failures with elements such as batteries and redundancy of production lines.

In some investigations, based on momentum and energy considerations, the forces were typically modeled as the rate of change of momentum of water as wave hitting the element (Wang,1970; El ghamry,1971; Tanimoto and Takahashi,1979; Broughton and Horn,1987; Kaplan,1992; Kaplan,1995).
Li et al. (1991) carried out a series of model tests for regular and irregular wave-current forces on piles.
Sundar et al.(1998) gave a detailed review on the hydrodynamics of slender piles and the variations of the hydrodynamic coefficients with the KC parameter.
For a large ocean structure, such as jetties and platforms, numerical models based on the perturbation-based potential theory in the frequency domain (Zhao and Faltinsen, 1988; Nossen et al. 1991; Teng and Eatock Taylor, 1995) were proposed.
Besides, numerical solutions based on directly solving the problem in time domain (Isaacson and Cheung, 1992; Kim and Kim, 1997; Jesper et al. 2000) has been obtained.

A review of the mechanistic design approach in pavement design was undertaken by Wardle et al. [7].
Mallela and George [11], Uddin and Pan [12] and Cho et al. [13] also employed ABAQUS in three dimensional pavement models.
Duncan et al. [18] first used the finite element approach in flexible pavements analysis.
To overcome this problem Duncan et al. [18] suggested a dimension of 50-times R (loading radius) in vertical and 12-times R in horizontal direction.

This antisymmetric gap was proposed as a qualitative measurement of the ionicity of the crystal, what confirms the proposal of Chelikowsky et al. [61] and affirms the results found by Bouarissa et al. [62].
Once again, this result for the ternary alloy is in agreement with the results found by Bouarissa et al. [68, 69], in their studies of the charge densities calculated for the valence bands for III-V alloys and in which it was found that the valence bands are affected by the presence of the disorder effect.
