Over 50 percent of CO2 emissions come from coal-fired power in the power sector[3], implementation of the energy-saving and emission-reduction policy in power sector has an important significance to the whole society’s energy saving and emission reduction.
Model for calculating pollution reduction and its value after power generation exchange The reduction of the kth kind of pollutant from power generation: (3) The value of the kth kind of pollutant’s reduction from power generation: (4) The total value of various pollutants’ reduction from power generation: (5) In the formula: is the emission reduction of kth kind of pollutant after power generation exchange, is the add-value brought by the kth kind of pollutant’s reduction after power generation exchange, is the total value of various pollutants’ reduction from power generation, is kth kind of pollutant’s emission coefficient of per unit of coal consumption, is the price of kth kind of pollutant of power purchasing side, is the price of kth kind of pollutant of power supply side.
Basic data This paper collected basic power generation information about area A and area B to start the case analysis; details as shown in table 1.
According the data above, we can see a significant benefit for inter-regional power generation exchange.
In order to deal with this situation, the energy-saving and emission-reduction measures are necessary to be applied in the power industry.

Reverse engineering has been used to gather dimensional data in order to model the actual wiper as datum.
Advantages of compliant mechanism are cost reduction and increased performance.
The cost reduction includes the part-count reduction, reduced assembly time and simplified manufacturing processes with it align with Design For No Assembly (DFNA) concept.
Designing Compliant Wiper Reverse engineering concept has been adopting to gather the dimensional data of current wiper.
Then by using CATIA V5, the actual wiper model has been modeled with dimensional data for actual size and shape, as in Fig. 2.

The differential scanning calorimetry and the method of cooling curves are used to obtain data on liquidus temperatures of oxide-chloride systems Gd2O3 – K Cl - GdCl3.
Alloys of gadolinium with cobalt and iron possess unique magnetic properties and, therefore, are applied for the production of data storages with high recording density.
The recorded melting temperatures (603 and 763 оС) and enthalpies (150 and 339 J/g) are in good agreement with the literature data [18, 19].
Results and Discussion We received data on liquidus temperatures of chloride-oxide systems Gd2O3 - GdCl3 - KCl, with the content of gadolinium oxide up to 0.09 mol. fraction.
This fact is consistent with the available literature data [6, 20] on the solubility of certain rare-earth oxides in molten mixtures of alkali metal chlorides.

Data showed that the total acidic number (TAN) value for crude B met the PETRONAS requirement for the TAN value below one using 1500 mg/L of DEA-PEG assisted by Cu/Ca (10:90)/Al2O3 catalyst.
Different concentrations of DEA-PEG (100-1500 mg/L) were considered to determine its effectiveness towards the reduction of NA content in crude B.
Data showed that the TAN values of crude B of 0.39, 1.1 and 0.84 mgKOH/g were obtained when as loaded from 10 to 30% (w/w) on the Ca catalyst surface.
The Ca/Cu(10:90)/Al2O3 catalyst calcined at temperatures of 900, 1000 and 1100°C was used to aid the removal process and, the data is portrayed in Fig. 3.
Elevation of calcination temperatures from 900-1100°C gave a significant effect on the reduction of TAN value for crude B from 0.65 to 0.39 mgKOH/g.

Data analysis The amplified DNA fragments for each accession were scored as present (1) or absent (0).
So it was reasonable that tissue culture population held 1/5 (RAPDs data) or 1/3 (ISSRs) genetic diversity of the source population.
But based on RAPDs data, tissue culture materials held more genetic diversity than the source population.
Lo declining sharply because this population only contained five different genets (RAPDs and ISSRs data).
Lo because this population contained over 20 different genets (ISSRs data).

The interval of the statistics was 30 minutes. 470 experimental data was collected which formed an original traffic time series. 4.1 Simulation experiment 430 data are selected as the training set, the last 40 data is test set.
The figure 5 shows the before and after the noise reduction.
Obviously, the prediction method mentioned in this paper can get the most approximate prediction value with the real network traffic data compared with the three methods mentioned above.
(1) Table 1 shows the prediction error correlation data of the prediction methods mentioned above.
It is revealed in the simulation result that the data fitting effect and the model prediction accuracy mentioned in this model is better than using LSSVM, chaos model or LSSVM-Chaos singly.

In the end 0.6ml of 0.02M sodium borohydride (NaBH4) was added to initiate the reduction process.
The catalytic reduction of these dyes was monitored by the recording UV–Vis spectral changes with time. 3.
Diffraction data inferred to the formation of pure crystalline phase Cu metal nanoparticles with face centered cubic (FCC) crystal structure having characteristic diffraction peaks at peaks (111), (200) and (220).The data obtained is in strong co-relation with previous reports concerning Cu nanoparticles [19, 20].
Noticeably very small reduction was observed with the passage of time.

The maximum punch load increases with drawing ratio, and maximum 5.5% of load reduction was measured when DR=1.74.
The research papers reveal that the reduction of forming load can be attributed to the various mechanisms; stress superposition, acoustic energy absorption in local regions(vacancies, dislocations and grain boundaries), reduction of interfacial friction, and thermal effect.[8] However, the load reduction in sheet forming might be only surface effect by the reduction of interfacial friction because ultrasonic energy is not enough to cause acoustic softening in the material.
Mechanical properties were obtained from uniaxial tensile tests of the SPCC and the results were characterized to use as input data for finite element simulations.
The relationships between anisotropy parameters and Lankford coefficients are as follows, ; ; ; (3) Mechanical properties and the parameters to describe hardening and anisotropic behavior are listed in Table 1, and those were used as input data in finite element simulations.
By comparing the experimental results when LDR=1.74, 5.5% reduction of forming load is attributed to 16.7% reduction of interfacial friction by ultrasonic vibration.

Furthermore, the integration of the measurement data into a process control system is intended.
The paper is structured in the following order: First, there is an introduction leading to the target, energy savings regarding the reduction of the annealing processes for valve solenoids.
Geometry deviations and manufacturing tolerances result in a reduction of the reluctance force due to unwanted air gap formation.
A further reduction occurs after the drop in radial force, which is due to the elastic deformation of the housing components.
After the reduction of all process forces, an increase in effective flow is maintained compared to the initial level.
