The temperature data was transferred through Ethernet to remote computer, and was displayed on the screen of remote computer.
When the system was set as automatic made, computer could regular steam supply based on temperature data.
Functions such as dynamic temperature display, controlling of steam and data backup could be achieved by the monitoring and controlling software based on Delphi which could not only monitoring and controlling remote usage of steam but also supporting data to build module for studying steam consumption.
It includes 16 Kbytes internal buffer for data transmission.
Serial Peripheral Interface mode used only four pins for data communication between the W5100 and the MCU.

Data was collected in the 2θ range of 5°– 90° with a step size of 0.0167° and exposure per step of 27 sec.
Because the raw diffraction data contain some noise, the background during the analysis was subtracted using the Sonneveld and Visser algorithm.
The data were then smoothed using a cubic polynomial function.
The activity of the catalyst was estimated by the number of produced products of the CO2 reduction reaction (mainly methanol CH3OH) per unit mass of catalyst per unit time recorded by a flame ionization detector of a gas chromatograph.

The CCT diagram of the high strength D6AC steel was plotted using the dilatometer data, microstructure investigation, and hardness measurements.
The increase of the cooling rates up to 1 °C/s led to the reduction of the bainite amount in the microstructure of the steel under consideration (Fig. 1, c) and to the increase of the hardness values up to 60.0 HRC.
The obtained data was implemented during the design process of the heat treatment technology for the drill bits being operated in severe conditions of impact loads and abrasive media [18, 19].
After the heat treatment the following mechanical properties of the drill bits were obtained: hardness 45,0 HRC; yield strength σ0,2 1360 MPa; tensile strength σB 1470 MPa; relative elongation δ5 12,5 %; reduction of area RA 24 %, impact toughness KCV 0,21 MJ/m2.

The offset reduction with CDS technique
enhances the sensitivity of winner-take-all (WTA) circuit and shows a sharp selectivity which makes
it possible to pick up only one winner pixel from each thermal object.
In particular, detection of important features reduces a large amount of image data and hence facilitates higher level processing tasks carried out on a host computer.
Architecture of Thermopile Array with WTA The offset reduction of our proposed design is based on an addition of CDS circuit which improves the comparison capability of WTA circuit and resolve more little temperature difference.
One is the previous research work without CDS noted as APS+WTA and the other is offset reduction with CDS noted as APS+CDS +WTA.

In the case of both steel grades is presented the reduction of the hysteresis, classical and excess losses, that occur after the applied treatments, using the concept of energy loss separation.
1.
This alloying permits the reduction of the effect of non-magnetic inclusions and to increase the grain size by metallurgical treatments [3].
This device can perform fast measurements, offers an AC frequency characterization and provides the hysteresis cycle, the relative magnetic permeability and the total power loss data.
The electrical resistivity increases with the temperature and for 700 °C the velocity diffusion of the Si atoms, dissolved in the Fe matrix is maximum, which determines the reduction of the hysteresis losses and the improvement of overall the magnetic properties, except for the magnetic saturation point, which decreases.
This is result of grain growth by annealing at high temperature, which generates a reduction of the number of domain walls and of the intensity of the micro-eddy currents [10, 11].

The influence of the curing age on the chloride permeability of HPC will decrease with the reduction of the water-binder ratio of HPC.
However,the reduction of water-binder ratio can result in the lower influence of the standard curing age on the chloride diffusion coefficients,no matter how many freeze-thaw cycles are applied.Under the identical condition of freeze-thaw cycles,the chloride diffusion coefficient of concrete is nearly suitable to a power function of curing age,the fitting functions are in Table 4.

Introduction
Nowadays, it can not only reduce natural resources consumption, but also avoid environmental effects due to solid waste treatment when beneficial using solid waste as secondary raw material to produce silicate cementitious materials, which plays an important role in energy saving and emission reduction.
Fig.1 System boundary of LCA for calcium carbide sludge cement clinker production Data Source Data collection of production processes.
The data of production process of using calcium carbide sludge to substitute limestone was obtained from one cement factory in Shan Dong province that uses the coal-fired pre-drying process and the coal consumption of pre-drying stage is 50.4kg.
The life cycle inventory related to Limestone is derived from the Sinocenter material life cycle data of Beijing University of Technology, while the inventories of clay, sandstone are from Ecoinvent database.
AP, POCP, HT and EP have declined by 5.2 %, 5%, 3.5% and 3.8%, mainly due to the reduction of electricity consumption.

Two sensors were used for location data acquisition.
Results and discussion Transverse loading tests During 3-point loading of specimen, acoustic emission data is recorded.
The AE data give a much clearer picture of progressing damage.
For highly damaged specimens the load reduction is significantly higher than to low damaged or virgin specimens.
Also this technique can find the relation between the severities of damages with the recorded AE data.
