Preparing for such training data is very difficult and expensive.
It is a hard work and costs much to prepare those training data.
It learns from both labeled and unlabeled data, which can reduce dramatically the number of labeled data required.

The main targets to be met by 2020 also known as the “20-20-20” are: ü To reach a reduction of 20 % of greenhouse gas emissions in comparison with 1990 (30 % if agreed); ü To achieve a share of 20 % of energy consumption to be produced from renewable resources; ü To improve energy efficiency in order to reach a 20 % reduction in primary energy use in comparison to projected levels [4].
Nowadays cities should have clear vision of sustainable development including not only CO2 reduction but also urban planning, resilience and energy policy [15].
The improvement of energy efficient performance is well reflected in the following data: ü Reduced heat consumption: 3 520 MWh/year ü Reduced electricity consumption: 675 000 kWh/year ü Reduced natural gas consumption: 608 450 m3/year ü Reduced CO2 emissions: 1 680 tons/year ü Reduced water consumption: 8 400 m3/year[9] Conclusions Micro CHP contributes to EU energy and climate goals with the increase of energy efficiency and CO2 emission reduction.

Both the unfavorable state of external environment and the dissatisfying level of factors of internal environment lead to strategic solutions about reduction or liquidation of certain directions of HR-activity as well as to the decrease of expenses for the defined initiatives.

The next fifth stage is organizational ensuring of control of key performance indicators, i.e. determination of: ‒ terms of indicators calculation (every day, once per week, every month, once per quarter); ‒ ways of providing information about the state of the indicator (form of reporting, way of placing and presenting information – a printed report, electronic base, cloud resource); ‒ sources of output data (names of documents, tables that include data, necessary for calculations); ‒ a person responsible for calculations (employee of the HR-department, analytical department etc).

The effects of varying the CR from 14 to 18 was studied on CI engine fuelled with waste oil biodiesel blends resulting in significant increase of brake thermal efficiency and reduction of emissions.
The dual fuel mode reported higher ignition delay when compared to diesel mode which was due to the reduction of air fuel charge temperature.
All the sensors are connected to the signal conditioning unit and then to the data acquisition system provided on the control panel board.
The data acquisition system is National instrument powered electronic system where the engine parameters and values are recorded in the system.
At CR 17, the delay period was observed higher than CR 18 which could be owed to the reduction in the mixture temperature at the end of the compression stroke and subsequently the peak pressure was also observed to be low.

After freezing and thawing, concrete often happens internal cracking, surface sapling, its quality and intensity decreased significantly; seriously affect the structure of using safety reduction its serviceable life.
During the trial test is divided into three aspects: (1) All samples of the compressive strength of the standard conservation 28d; (2) freeze-thaw samples before freezing and thawing, after freezing and thawing 25 times the sample quality and strength; (3) the compressive strength of freezing and thawing test pieces. 2.3.2 Analysis of test data (1)Benchmark specimen strength of 28d 28d compressive strength of concrete was measured in each group (Table 2).
(3)Mass loss rate of freeze-thaw specimen Concrete due to freeze-thaw erosion by frost heave pressure cracking, spilling produce mass loss, while structural damage of strength reduction is to speed up, it seriously affects the use of structures security.
And antifreeze content is 6%, it increases after the mass loss reduction, quality, larger changes, the laws of different fiber content in the quality of 3 ‰ for the loss and the other two points of a large margin.
At the same time, according to analysis of relevant data, we can see that fiber content for the 5 ‰ (C1, C2, C3) and B3 Group compressive strength of concrete for 28d is lower, it is difficult to ensure that the structural strength of concrete to meet the requirements.

The data was interpreted using the work-ofindentation model, and suggests that the coating shows a considerable hardness increase compared to the bulk property of the same material, but also a moderate increase compared to the substrate.
The basis of new method rests with the investigations of the process of metal oxide reduction in various reducing mediums under impulsive mechanical activation conditions.
In particular, the intensification of the reduction process of some metal oxides in the medium of another active metal, organic solvent and hydrogen atmosphere has been reported in our earlier publications [6-7].
The data presented may be thought to constitute some representative cases of achievements to date, with highlights on some of the important practical results.
The second stage, coating deposition proper, is responsible for the in situ reduction of coating forming oxides (TiO2 and Cr2O3) leading to the formation of highly chemically active and cohesive pure metal powders and the eventual coating deposition.

The research work is aimed to provide scientific data on rheological behavior and fired properties of Ipoh clay from Perak, Malaysia and its application in ceramic tiles.
Firing temperature of 1050 °C – 1250 °C shows drastic increase in linear fired shrinkage from about 3.5% to above 10% together with drastic reduction in water absorption from about 19% to 5%.
Ipoh clay is considered as dimensional stable with range of linear fired shrinkage of 2.5 to 3.5% from firing temperature from 1000 – 1050 °C, which also shows slight reduction in water absorption that fall within 18 – 19%.
Fig. 4 also figured out that above firing temperature of 1050 °C, a drastic increase in linear fired shrinkage from about 3.5% to above 10% together with drastic reduction in water absorption from about 19% to 5%.

In the current study, grain-scale variant selection is described in terms of quantitative data analysis.
Instead of using conventional ODF's, here Rodrigues-Frank space is employed to represent the orientation data.
If each data point in the orientation map is considered as a "grain" with a specific orientation, the data can provide information about the "texture" of the scanned area.
The intensities were calculated from 1.3 million data points, of which about 96% were from the bcc and 4% from the fcc phases.
Here, a recent dislocation-based model [3, 9] is evaluated using the orientation data obtained from individual γ grains.

SVM supports small sample of data, but also has advantages as low computational complexity, high sparse model, support for multiple classification and class membership probability calculation and so on.
As shown in Fig.1, we choose high fidelity bullet pinhole type noise reduction micro sound listener to collect acoustic signal in circuit breaker operation.
Fig.3 Acoustic signal EEMD decomposition envelope 3 Experiment Analysis Data of this paper comes from the collection of data LW59-252 type SF6 circuit breaker, normal, institutional jam, lack of lubrication of the experiment data of acoustic data under three kinds of breaker status. 3.1 Feature Extraction According to the fault feature extraction method mentioned in section 2, calculate energy entropy IMF under various states as shown in Table 1.
Taking experimental data of high voltage circuit breaker were calculated energy entropy of EEMD decomposition as feature vector input support vector machine, half of the data which is used as the training data, the other half as the test data set which is used to test the correctness of diagnosis.
At the same time, the SVM method can be applied to the fault diagnosis of high voltage circuit breaker which is small sample data set, and construct more reliable model through choosing different kernel function. 4 Conclusion In this paper, the high voltage circuit breaker fault diagnosis based on acoustic data is mainly studied because of there is very strong sound signals when high voltage circuit breaker acts, the acoustic signal will change while the circuit breaker motion state changes.
