Data source: Yole Power SiC 2016: Materials, Devices, Modules, and Applications report , [1].
There is no available data to track production and capacity of power modules.
Most data from industry members and equipment manufacturers are collected via interview, and data from material suppliers are obtained via request for quotes or interviews.
Often, this can be achieved by collecting data from many different sources and providing only aggregated anonymized information.
However, in cases where only a small number of data points (or only one data point) can be obtained for a given input, and thus the data cannot be sufficiently anonymized, we are unable to publish specific input assumptions.

However, about 9% and 37% reduction in compressive strength in HVS cement pastes is observed due to use of 80% and 90% slag, respectively.
However, significant reduction in compressive strength is observed in higher slag-fly ash blends with increasing in fly ash contents.
Mass and differential temperature data were acquired with respect to furnace temperature.
These significant reduction can be attributed to the slow pozzolanic reaction of fly ash and slag in these HVSFA cement pastes.
However, the nano silica used in this study was synthesized by a chemical precipitation method confirmed by the manufacturer whose CO2 emission data is still not know.

In article the structural analysis of power consumption of the building of house series 1-528 KP is carried out, on the basis of the analysis of actual data of heat consumption and the carried-out tool energy audit the data, allowing to estimate a condition of systems of heating, power supply, water supply are obtained.
The calculation of the specific thermal value of the building Based on the data shown in Tables 1, calculation is made of the basic value of the required resistance to heat transfer of exterior enclosing structures .
The comate of Leningradskaya has been chosen as the initial climatic data for design (the calculation is based on climatic variables of Kolpino town (Table 1)).
The number of degree-day of heating season for residence buildings situated in the territory of Leningradskaya area is 5221 °C·day (see data in Table 2).
Then the operations expenses reduction (loss of the heat power in 1 m2 within one heating season) after the thermal insulation of the outer walls will be: ΔO = (U1 –U2) ∙ 0.024 ∙DDHP∙CТ/1163 = (1- 0.31) ∙ 0.024 ∙ 5221 ∙ 1351.25/1163≈ 97.1 (rur/m2).

E-mail fangruishaqiu@163.com Keywords: Grass brick house, Village house, Energy conservation and emission reduction Abstract.
To make this new type energy saving and emission reduction technology on grass brick building can improve, promote to the more rural, and provide the reference which can better service for new countryside construction on using building materials.
Through the questionnaire survey, field measurement, communication methods to understand the practical living situation of grass brick building and to collect the data, and then provide reference for the construction of grass brick building which is counted in low-cost housing promotion in rural area of northeast China.
These data show that the grass brick house is economic and environmental green building.

This article addresses mainly on the basis of rough set theory the prediction on medium and long term loads of power distribution network that is affected by uncertainty of historic data.
Suppose for Suppose attribute subset, if ,so we call is Reduction for .
Preprocessing For this case, the load data for certain territory for 1998~2005 and relevant economic data will be used as data sample to make prediction on power load and energy for such territory in 2006.
Reduction results can trade as the grey GM (1, n) model input variables, thus we can get prediction results and error analysis
Grey prediction requires less sample data and does not consider the rule of distribution and variation tendency.

The AR films were subjected to reflectivity inspections, a 5.5% reduction in reflectivity was obtained.
Raman data is widely used for the characterization of diamond films due to its ability to distinguish between the sp3 and sp2 bonding types.
For samples derived from oxalic acid, an average of about 5.5% reduction in reflectivity was obtained.
As for phosphoric acid, only a reduction of about 1.6%.

The Data Mining technology brought forward.
Data mining, also popularly referred to knowledge discovery from data (KDD), is the automated or convenient extraction of patterns representing knowledge implicitly stored or captured in large databases, data warehouses, the Web, other massive information repositories, or data streams.
Through data mining technology, we can solve these problems to some extent, so that soldier's result data can be used in the greatest degree and more information for the organization of training can be provided.
In the aspect of data integration, we make forces’ soldier as research object, to get the fitness and skills survey data of related soldiers through statistics on results, to get the basic situation information and result data according to existing "Military Information Management System".
Before data mining, we preprocess the data with data cleaning, conversion, reduction and so on.

Density and open porosity of the NiO/SDC ceramics before and after reduction were tested by the Archimedes method.
Single cell test was performed on a SOFC based on Ni/SDC anode supporting SDC electrolyte (50µm) with a homemade data acquisition device, using H2-3% H2O as fuel gas and air as oxidation gas.
Table1 Open porosity and relative density of the NiO/SDC cermets before and after reduction Sintering temperature /°C Relative density /% Open porosity /% Before H2 reduction After H2 reduction Before H2 reduction After H2 reduction 1250 75.32 54.90 24.23 38.50 1300 84.00 63.00 13.40 36.76 1350 88.00 66.00 10.54 33.65 1400 89.99 68.70 10.00 30.42 Results and Discussion Phase composition and structure of the NiO/SDC powders are shown in Fig.1.
Table1 lists relative density and open porosity of the NiO/SDC ceramics before and after reduction at different temperatures.
Open porosity of the Ni/SDC cermets is higher than that of the NiO/SDC ceramic, this can be ascribed to the reduction of NiO into Ni, remaining pores in the structure [2].

This extension of the file, type - 3D mesh data, divides the object into triangles with respective points and normal vectors (Fig. 2).
In Fig. 4 is shown how rude and inaccurate will come out the object texture if we make the file reduction to the 3000 points from the 385,976 initial points (a reduction of 99.27%).
So by increasing the number of points will increase the profile accuracy, but also will increase the processing time of data.
Object reduction to 3000 points and real object picture Careful analysis of grid meshing process led to the reduction to 198,080 points (a reduction of ≈51.3%), a value sufficient to maintain the real values of the profile (Fig. 5).
Object reduction to 198080 points Fig. 6.

The improve method of airspace filtering has the advantage of eliminating this drawback to get the ideal effect of noise reduction.
The results from the experiment have established that this method has a better effect of noise reduction than mid-value filtering and its improved methods, with the retention of the image details in an effective way. 2.
The mid-value filtering is to a large extent subject to the size of the filtering window in terms of the performance of noise reduction, with the existence of the contradiction of checking the image noise and protecting the image details.
In Document 1, the mid-value filtering of central weighting is presented, in which the image element in the window is rendered different value to adjust the contradiction between the noise reduction and details protection, resulting in the sacrifice of noise reduction capability.
The video data from the CCD TV camera is transmitted after SAA7113 decoding to FPGA which will make a treatment of filtering and compressing on it, after which the data shall be transmitted to the monitoring host machine through the Ethernet.
