Schematic illustration and specification of residential SOFC-CGS
Building data and input loads.
The input load data at 1-minute intervals of the SOFC-CGSs simulation programs [4] includes occupant-related electricity, thermal load by air-conditioning, and the domestic hot water demand for the winter calculation period (from November to next March).
Finally, input load data by power and heat (at one minute intervals) was created based on obtained data for calculating period of winter.
Result and discussion The output data of the SOFC-CGS simulation program is energy demand of electricity and natural gas bought from the company, which can be converted to primary energy by conversion factors.
It claims that primary energy demand reduction is increased with air temperature decrease.

Each pair of tracks are installed with a data collector and all data collectors carry out a two-way data exchange with the same measurement controller.
The measurement controller is used to receive and deal with both the weight data from the data collector and the video data from video server.
The equipments required reduce a lot which lead to a greatly reduction of investment costs.

It follows from the obtained
data that the hot working with the following accelerate cooling under industrial conditions does not
develop a tendency toward corrosion cracking in 3% agueous NaCl solution.
This is confirmed by experimental data for the effect of steel chemical composition and heat-treatment schedules on its tendency toward ICC.
With an increase in dislocation density a tendency is observed toward a reduction in corrosion rate (Table 2).
In contrast to data obtained in [9] for a similar steel given TMP, the grain size and overall amount of carbide phase in this case has almost no effect on ICC.
It follows from data in Table 2 that steel TMP-worked under industrial conditions practically does not develop a tendency toward corrosion cracking in 3% aqueous NaCl solution.

In that sense model reduction based simulation appears to be a very
promising alternative.
Indeed, by no more considering the initial condition of a transient problem as a static input data but as an extra- coordinate similarly to space and time, we demonstrate that it is possible to parallelize efficiently the computation and even reach real-time in some cases.
More details regarding the PGD method and other model reduction methods are given in [1, 2, 5, 7].
Instead of considering it as a static input data, it can be introduced as an extra-coordinate of the model, similarly to space and time.

The data were collected in the range between 10 and 90° in steps of 10°/min.
Conclusions The LiFe0.98Ni0.01Nb0.01PO4/C composite was synthesized carbon reduction route using FePO4·2H2O as precursor.

This approach can also be used to target recognition based on radar data.
Moreover, without dimension reduction, the model’s complexity is high and the learning speed is low.
Assume the original input data has been normalized.
The spectral data come from http://www.ucl.ac.be.
The dimension of the mass-spectrometric data for building mode is 1000.

And assessment data acquisition difficulties, the assessment field dependence and confidentiality are strong; Assess needs more and more.
Node conditional probability can be determined by learning a large number of sample data or the knowledge of experts in the field.
Attribute Reduction Algorithm attribute dependence progressive genetic reduction based design method.
For building assessment model, we compare SASR with CTR data table in literature [5], setting that fitness function is calculated based on the dependence and genetic algorithm takes optimal preservation strategy.
When the number of instances of the data sets and the number of original attributes are less, the advantage of SASR on the time complexity is not yet clear, but when increasing the number of instances of the data sets and the original number of attributes, the advantage of SASR on the time complexity gradually shows up.
