The range of measurements provides a large amount of experimental data on temperatures, flow rates and pressures in the engine cooling system.
Then we could simulation results in each individual combustion engine checked by the measurement data.
There is also good to see a reduction in temperature to the cooling channels.
The main point is to calculate the temperature of the exhaust valve seat using the FEM The range of measurements on the engine provides a large amount of experimental data on temperatures, flow rates and pressures in the engine cooling system and especially the effect of different configurations on the adjustment of temperature in the cooling mode of the temperature in the monitored areas of valve seats of the exhaust valves.
For temperatures of the valve seats is important (known) the observation that the temperature reduction is needed to ensure an increased flow rate of the coolant in the cylinder head parts, which are measured.

This paper argues that the key to LED industry develop in Jiangsu Province is establish a relatively sound government guidance mechanism, and put forward the system strategies from the angle of government subsidies, technological innovation, financial supporting, human resources training and international exchange, so that can promote LED industry development in Jiangsu Province, seize the top technology in domestic and international, foster the new economy growth in Jiangsu Province from long-term, achieve emission reduction target, and realize sustainable economy and society development in Jiangsu Province.
We can find in the data that lighting energy consumption has become an important component of national energy consumption.
(3) Industrial Chain Developed in Depth The proportion of LED used in commercial space has increased because of China increasingly stringent emission reduction requirements.
The resource sharing platform should integrate the LED standards, technical data, information, equipment, books and documents and other elements with external technical resources and form interconnection relying on businesses, universities, research institutions, libraries in the form of information networks.

The graphene uniformity can then be evaluated from the distribution of the data points making up this map.
The circled data points correspond to graphene grown on 3C-SiC.
a) and b) are modified from results presented elsewhere [5] in order to add data pertaining to 3C-SiC substrates.
In this case there is no distinguishable difference between cubic and hexagonal substrates, but this may also be due to insufficient amount of data for graphene grown on 3C-SiC.
Circled data points correspond to graphene grown on 3C-SiC.

The magnitude of thermal conductivity also increased with V doping at Mn site, but shows a reduction for V doping at Ca site.
However, V doping at Mn site sample shows a reduction of ZT at 0.0028 for CaMnO3 at 1000 K which is much lower than CaMnO3 at 0.08.
The calculated Seebeck coefficient as a function of temperature shows a good agreement with experimental data for CaMnO3 [14].
The ZT data are presented in Fig. 3(d).
Compound with V doping at A site shows enhanced ZT at 0.14 at 1000 K, but compound with V doping at B site shows reduction of ZT to 0.0028 at the same temperature due to much lower magnitude of Seebeck coefficient due to much higher effective mass of carriers.

The data-acquisition system is mounted in the transition piece.
The data-acquisition software allows the continuous monitoring of accelerations.
All data receive a time-stamp in order to be able to correlate them with the SCADA and meteo data.
In Fig. 3 the SCADA data for the monitoring period are shown.
In this paper a total of 2016 data sets have been analyzed.

The current-voltage characteristics of Al + implanted 4H-SiC p +n junctions show an important reduction of leakage currents with diode aging at room temperature.
The data are the average of the measurements of three diodes.
Each data of the plot is the average of three diodes measurements and the error bars are the standard deviations of this average.
Nevertheless a reduction in the diode reverse current of four orders of magnitude seems too high to be attributed only to the passivation of the diode periphery.
For justifying the trend of the data in Fig. 2 and 3 Fig. 4.

It was found that cold rolling with a reduction of 15% or equal-channel angular pressing (ECAP) up to a true strain of ~1 leads to acceleration of age-hardening response of this alloy.
In addition, experimental data on effect of this strain on a dispersion of the secondary phases are contradictory.
(ii) The plates were cold rolled with a reduction of 15% (ε~0.16) and finally artificial aged at 180°C for different times.
All misorientation maps were obtained with a sufficient level of indexing to provide reliable data.
Cold rolling with a reduction of 15% leads to fraction of LABs and density of dislocations of ~87% and ~2.2´1016 m-2 (Fig. 4a and b), respectively.

It leads to a reduction of machining time tero of 17 % due to an increase of the discharge frequency fe and thus to an increase of the MRR VW.
The displacement a and voltage U data were synchronically measured and saved to a computer by using the scope of the type PicoScope 3405D by Pico Technology.

Daily climatic data used in the studies were obtained from weather stations operating at each of the Centers (Fig. 1).
This roughly coincides with a 25% reduction in irrigation from the long-term net requirement.
The 25% reduction in net irrigation could translate into 35-55% savings when compared with sprinkler and furrow irrigation systems that typically operate at 85% and 65% application efficiencies, respectively.
The 25% reduction in net irrigation needs was associated primarily with the reduction of in-season deep percolation, a non-beneficial component of the water balance [4].
Higher irrigation water-use efficiencies were obtained with the longer 7 day frequency because of better storage of in-season precipitation and because of reduction in deep percolation below the root zone [5].

Data presented here were obtained at an engine speed of 1500, 2000, 2500 and 3000 rpm.
It is observed that a clear reduction in smoke emissions for all values of speed when biodiesel is used.
The reduction in CO emission of biodiesel mainly due to oxygen content of biodiesel which enhances the complete combustion in the cylinder [8].
CO2 emission was related with the carbon content in the fuel and from the Fig. 6 it shows that slightly reduction of CO2 for higher biodiesel blend was found especially for B10 biodiesel at all speeds.
(ii) The biodiesel fuels produce significant reduction in the CO, CO2, HC and smoke opacity compared to ordinary diesel fuel at both variant engine speed and engine loads.
