Test data and analysis Water content test data.
The test data of water stability.
With the further reduction of water content, the bond strength between asphalt and aggregate begins to be restored, making the splitting tensile strength increase.

This methodology initially gathers data in the plant to enable detection of critical tasks, through a primary examination of the resources assigned to the workstation, its location and use, together with the opinion of the operative carrying out the work.
For 3D design, the following types of data are needed: measurements of work machines, equipment and tools, lay-out of the workstation and set of tasks or activities which the operative performs there during the manufacturing process, as well as the nature of the material being handled.
The majority of ergonomics projects include, amongst other costs: personnel, equipment and material and the possible reduction in productivity due to implementation and study phases.
Together with these costs are the benefits which may be gained: reduction of compensation costs, increase in productivity and resource life-cycle and improvement in company image and working atmosphere.
The methodology described not only gathers technical data on workstations, but also the opinion of the operative who performs the tasks in the plant, thus providing a real insight into carrying out the process.

Corrosion Test: Table 1 shows the potentiodynamic polarization test data for the composites in different media.
The data indicate that the composite corrodes faster than the base metal/alloy in all three solutions.
According to these observations, it can be deduced that in aqueous solutions, TiB2 serves as an inert electrode for hydrogen and oxygen reduction and therefore acts as a cathode.

Moon et al. [3] showed the effect of combined hot die and cold punch on the reduction of springback of aluminium sheets experimentally.
“Table 1” shows the data used in the simulations.
Data Used For Simulation Fig. 3.The finite element meshes used in U bending.
According to recorded data in tables in U-die bending there isn't any springforward and all defects are springback.

The main objective of this paper is to evaluate the thermal comfort conditions by using a CPMV model and an adaptive model based on on-board cabin environmental measured data.
The reduction of cabin pressure and very low RH at cruise altitude will affect several terms in the bio-heat balance equation.
Because the RH will decrease quickly below to 30% in aircraft cabin, hence the following linear model is proposed to create a depedency of wb on cabin RH: (4) (2) Clothing vapour resistance ISO 7933 suggests to use Fpcl for the calculation of clothing vapour resistance (Re)[3]: (5) where L is Lewis ratio, ℃/Pa; hc is the convective heat transfer coefficient, W/(m2℃); Fpcl is the reduction factor for evaporative heat loss with clothing compared to the nude person and is defined as: (6) where Icl is intrinsic clothing insulation, m2℃/W; hr is radiant heat transfer coefficient, ±5W/(m2℃); fcl is clothing surface area factor
The assessment results of CPMV model for 25% RH level, 30% RH level and uncontrolled RH are shown in Fig. 2 by using the measured data of Flight 1and Flight 2.
A CPMV model was applied to assess the thermal comfort in the civil aircraft by using the in-flight measured data.

Among many other things, the cost reduction plan of a power system depends on the reliability of an optimized system.
First part: Load the ‘forecasted load profile’ sample data according to minimum and maximum load variation at the required hour (1 to 24 hours). 2.
The datasheet containing data related to the LCOE calculation can be referred from Table 1 taken from [4].
fitnessmaximum=fitnessminimum (5) As soon as the termination criteria is met (refer to: Eq. 5), the data of most suitable generation size for each generator is determined and the sum of each generator sizing (which is within the search space set) should be enough to generate the required load demand power for the specific hour while minimizing the cost of generation.

Simulation of the implanted profiles after all epi steps, model is based on internal SIMS data.
Spots with localized avalanche were observed for all samples and these may be related to local barrier reduction due to material defects.
As suggested in [4], the VHE data for the 0.018 cm-2 die are close to expectation.
The data in Figure 7, show that the Rsp values rise with a quadratic dependence on temperature.
Overall, the use of channeled implant offers a reduction of the number of process steps needed to fabricate the structure and makes for a viable alternative to a traditional device architecture.

Experimental data obtained from MGID-sin2y method can easily be treated if the measured interplanar spacings are converted to equivalent lattice parameters, i.e., {hkl} = {hkl}.
Sample Reduction in the first rolling (%) Time of annealing at 250°C (min) Final reduction after first and second rolling (%) A not treated initial sample B - - 92 C 61 120 92 D 61 60 92 The X-ray measurements were done in two directions (f = 00 and f = 900, see Fig. 1b) and for two incidence angles (α = 50 and α = 150, Fig. 1a) in the case of MGID-sin2y method.
Exemplary {hkl} vs. sin2y plots presented in Figs. 4 and 5, show a very good adjustment of the theoretical data to the experimental one.
Using the same data treatment as for Al powder, we have determined two components of the stress tensor, i.e., σ11 (in RD- rolling direction) and σ22 (in TD-transverse direction) for two depths (5.18 μm and 14 μm) in the case of MGID-sin2y method and for the approximate depth of 18-34 μm when the standard sin2y method was applied.
