This will be able to compare the data obtained in
Nigeria with that of Germany and validate the results for the two different regions.
Statistical Analysis The data collected for rainfall, sediment yield and infiltration would be subjected to two-way analysis of variance (ANOVA) in accordance with the procedure of Steel and Torrie.
Interception is increased as foliar development in treatments A and C, which leads to reduction in runoff in the case of treatment A and C.

The special case of orthotropy, where two main directions have the same material properties leads
to a further reduction
Herein assumptions like perfect fibre matrix connection are made, which lead to differences in comparison to experimental data especially in high fibre volume contents.
Another example for a semi-empirical approach is the rule of Halpin-Tsai [6]: ηφ ξηφ − − = 1 1 Rp p (25a) ξ η + − = RF RF pp pp / 1/ (25b) The p stands for the property that has to be homogenized and ξ is a factor that depends on experimental data as well as fibre package and fibre geometry.

It should be noted that a small amount of research has been conducted in the sector of noise reduction applications.
In order to determine the transfer function between the two microphones, a data acquisition system was also used to process and record signals.
For interpreting sound waves to digital signals MATLAB software was utilized to save the output signal data.

The data intuitively showed the temperature drop of the narrow gap between wafer and heater was 15~30K when the outlet pressure of the chamber was in the range of 1~10Torr.
Twt decreases when the height of the gap H1 increases, and the reduction degree are roughly equal under the same pressure, that is to say, Twt is almost negative linearly related to H1.

The scarcity of historical data has limited the widespread use of fibers in concrete applications.
By utilizing data from previous research, a comparative analysis will be conducted between hybrid reinforced concrete containing a blend of fibers and conventional concrete without fiber admixture [7]. 3.
• Hybridization in reinforced concrete pavement enables a thickness reduction of up to 30% through enhanced compressive and tensile strengths.

When iron is difficult to diffuse into the coating through the Cu interlayer, the reduction of Cu content in the coating is beneficial for achieving higher hardness.
The relevant fitting data by Tafel method [32] is listed in Table 4, where Ecorr is the corrosion potential and Icorr is corrosion current density.

This process of data sharing, between ANSYS structural and CFX fluid field, continues until these fluid forces and the structural displacements fall below a prescribed convergence criteria.
All the physics and data are shared with this window.
Fin's deflection results in flow velocity reduction in fluid domain over it which affect in pressure increase.

The aforementioned reduction of the magnetic interactions due to Co doping is triggered by a Mn content exceeding yMn=30.
In order to provide a consistent outline we considered the mean values of the DV/V data in a restricted range of the transformation, i.e. by taking into consideration the diffraction patterns which returned a refined phase fraction in the range ≈15-85%.
The overall consequence of this complex situation, together with the isotropic thermal expansion of austenite occurring at a different slope, gives rise to a certain degree of scattering of the DV/V data with temperature (Fig. 8); nevertheless, a mean DV/V value (being for this sample slightly higher than ≈0.9%) can still be reliably estimated.
