The performance gasifier design will later be tested for performance and be used to measure data experimentally.
The postulated model is then derived to obtain an equation that will later be tested using data obtained from the experimental.
Experiments carried out to obtain data that is useful in determining the parameters of heat and mass transfer coefficients that are modeled in empirical equations.
The data that has been measured is used as a tool to validate the postulations that have been set.
The position of the thermocouple is placed at 4 heights to get temperature distribution data along the reactor height.

Based on the monthly datasets, including the number of traffic accidents, casualties and meteorological data, the relationship between the traffic accidents and meteorological conditions is studied.
Data and methodology 2.1 Meteorological data The monthly meteorological elements including relative humidity, atmospheric pressure, precipitation and visibility at Beijing observatory from Mar. 2007 to Feb. 2010 are taken in the study. 2.2 Traffic accident data The monthly traffic accident data are the numbers of traffic accident and casualty on BTT expressway from Mar. 2007 to Feb 2010.
The casualties increase with the reduction of surface pressure.
Based on the monthly datasets, including the number of traffic accidents, casualties and meteorological data, the relationship between the traffic accidents and meteorological condition is studied.
In addition, the correlation is much higher if the data in Oct. were deleted.

The numerical model has been validated by comparing the ABAQUS numerical results to the experimental data obtained by an ad-hoc campaign including mechanical tests under variable thermal conditions.
Each data acquired from the heat flux meters has been filtered and linearized.
In particular, in Figure 6 the strains at 3, 4, and 5 locations (according to Figure 2), as a function of the applied load are introduced and compared to experimental data measured during the first cold mechanical loading step.
It is worth to notice that, despite the incident heat flux has been extrapolated from few locations to the entire panel by the ABAQUS mapping function, the obtained numerical results show a good agreement with the experiment data.
Again, the agreement between numerical results and experimental data is very good.

The development of the Friction Stir Welding (FSW) process and its
application to aluminium alloys open new opportunities for obtaining high quality joints also on
particle-reinforced aluminium-based composites, but relatively few literature data are present on this
topic [2-4].
Fatigue life data and Manson-Coffin curves for the base and friction stir welded W6A10A and W7A10A MMCs. 0.001 0.010 10 100 1000 10000 24 Cycles ∆ε/2∆ε/2∆ε/2∆ε/2 W6A20A W6A20A FSW MC W6A20A MC W6A20A FSW W7A10A W7A10A FSW MC W7A10A MC WA710A FSW increases the strain hardening exponent and the elongation to failure.
The experimental results of the low-cycle fatigue tests and the interpolation of the data according to the classic Manson-Coffin model [6] are reported in Fig. 5.
The experimental data show a high dispersion both on the base and FSW specimens, which can be related to the intrinsic material in-homogeneity typical of composites produced by molten metal processes.
However, in general, the lower fatigue life of the FSW material could be related to the microstructural modifications induced by the process, which also led to a reduction in hardness and tensile strength, but probably the main influence in the fatigue life reduction is the high roughness induced by the FSW, mainly on the surface in contact with the tool (Ra=3.5÷5.5 µm).

The sample with molar ratio of Zr : Y : Ni = 100 : 4 : 30 was with
reduction temperature of 900 o
C.
Samples with molar ratio of Zr : Y : Ni = 100 : 4 : 10 were with reduction temperature of 900 o C and 850 o C.
This is interrelated to particle sizes, atomic mass of the reduced metal, and reduction mechanism, etc..
This means that tungsten-oxide is reduced more easily than nickel-oxide at lower reduction temperature.
in the brackets of the table represent the reduction temperatures in hydrogen for 1 hour.

The main idea is to approximate the machined surface using the inspection data and the basis functions of the nominal NURBS surface and to get the error distribution of the surface.
Many researches have been carried out on the compensation of machining errors using the OMM data.
Cho[1] presented an integrated machining error compensation method using OMM data to effectively reduce the machining error in the end-milling process.
The machined surface (Sm) can be approximated by adjusting the parameters of the nominal surface (Sn) according to the database measured by on-machine probing (the simulated data is used here).

In this context, analytic quantification of strength
and deflection characteristics of structural components with web openings must be developed through
research data collected through controlled laboratory testings.
A reduction factor 1α of 35% was found to be an effective tuning parameter for the deflection prediction as seen in Fig.6 to Fig.10.
A reduction factor 1β of 25% was found to be an effective tuning parameter for the deflection prediction as seen in Fig.6 to Fig.10.
A reduction factor, 1γ of 15% was found to be an effective tuning parameter for the deflection prediction as seen in Fig. 6 to Fig. 10.
Thanks are extended to Hume Concrete Product Research Centre (HCPRC) for several useful discussions and generously provided large collection of prestressed beam tests data.
