Simulation results were validated against experimental data by comparing surface roughness values obtained from simulations with those measured experimentally.
Increased pressure (up to 80 bar) led to a significant reduction in roughness, with further pressure increase showing diminishing effects due to saturation in media-workpiece contact area.
Experimental results confirmed that increasing extrusion pressure and cycle count contributed to a significant reduction in surface roughness, enhancing the biocompatibility and longevity of the implants.

Graphene oxide is electrically insulating material due to its discrupted sp2 bonding networks and aliphatic sp3 – hybridized domain but the electrical conductivity of graphene oxide can be recovered by restoring the π – network via reduction process [7].

We used a structured questionnaire to collect data concerning the characteristics of the farms and the practices in the rubber plantations.
We did not observe a reduction of tapping frequency during the leaf fall season as we did in a previous survey conducted in 2008 in the South.
And in the North and Northeast, the long dry season induces a reduction of the tapping period.

Introduction Exhaust gas recirculation (EGR) is a commonly used technique for the reduction of nitrogen oxide (NOx) emissions from internal combustion engines which attracts more attention around the world[1,2].
However, with the reduction of NOx emissions, the application of EGR technology will also produce some disadvantages, such as the enhancement in brake specific fuel consumption and particulate matter emissions[5].
Fig. 3 Agglomeration number-size distribution Fig. 4 Number concentration and mean aggregate as functions of EGR rate particle size as functions of EGR rate In consequence, the resulting number concentrations, as well as mean aerodynamic of diesel particulates were shown in fig. 4 by means of statistical methods using measurement data in fig. 3.

The strains on main bar and concrete and vertical deflection were measured using LVDTs and connected to the data logger to record the reading (Fig. 2).
It can be seen that the rate of deflection per unit load is higher after the initial crack appear which is an indication of the reduction in the stiffness of the cracked beam.
It can be noted from the results that increased in number of cracks caused the reduction in cracking spacing.

Introduction With China's laws and regulations to further improve energy saving and emission reduction, the society has pay more attention to reduce fuel automobile tail gas.
In general, the energy reduction for storage battery is beneficial to the improvement of the system efficiency.
Specific simulation parameters are as follows: vehicle drag coefficient 0.30, effective cross sectional area 2.3㎡, car weight 1500 kg, the engine displacement 1.4 L, maximum power 65kw, motor power 33kw, battery capacity 20ah, rated voltage 168v, SOC theoretical value 0.7, gearbox for five speed shift, the rest of the parameters comes from the literature [6] data.

(4) i) Terminal power consumption The minimal received power of base station is , to ensure data transmitted normally, the minimal transmission power can be given by:
The slight reduction of throughput is because of network blocking, when number of users increases.
The reduction of cost effectively demonstrates the advantage of multi-access algorithm.

There is a lot of bibliographical data concerning the diffusion chromizing process, in particular, problems connected with hard carbide layers produced by the pack powder method, which are quite well expounded [6–9].
Chromium is transferred to the steel surface by one or more of several possible deposition reaction (of interchange, of reduction, or of thermal dissociation types) and then it diffuses in it to create a layer.
Reduction of chromium concentration in the layer was associated with the simultaneous increase of iron concentration, while the concentration of carbon remained at the same level of about 9 wt. %.

However, conventional photolithography requires size reduction technique or process to achieve nano-scale devices [4-5].
Based on experimental data, in order to achieve the target gap size of 0.98μm, an optimization was made due to produce semiconductor chip biosensor.
