Abstract.
max: t As well as, t∈[0,1], Based on really statistical data of base year, the authentic benefit matrix BL and cost matrix CL are acted as the starting point of production; the neighboring year or period production will shift in the fuzzy factor direction from the origin.
To pick up data of base year 2010 from statistical yearbooks of Tianjin Binhai New area, production output layout of 37 industrial sectors is obtained and displayed in table 1.
Added value of carbon emission intensity per profits and taxes varies from minimum to maximum, so the new constrained conditions are shown as follows: xi>=1-si*t,i=1, 2, …, 37 The resulting shows that industrial layout is divided four sectors’ groups to estimate the industrial development depended on data of base year.
Optimal planning of renewable energy-integrated electricity generation schemes with CO2 reduction target.

Fig. 3 shows the PolyMAX stabilization diagram for the reference data set S0.
The available data for each damage scenario are split in two equal parts.
The variances in Eq. 1 are estimated empirically using the available data.
Online (thus, using validation data), at each sample, the current VAFs are computed.
In this case, 2 s of data were used to identify a new model.

The as-received samples were tested and used as baseline data.
The system is equipped with a specialized data acquisition, data reduction and data plotting software.
The fracture strain however, experiences an abrupt reduction in value that starts after ½ month of outdoor exposure (Fig. 1).
This reduction reaches 38% after an additional ½ month of exposure.
As fracture strain is generally thought of as measure of material toughness, its reduction is an indication of lower toughness.

SEM data show that the average MnO2 particle size is 482.80 nm.
Figure 2 illustrates the mechanism of metal ion reduction to form particles.
The activation phase is in which the reduction of metal ions and the nucleation of reduced metal atoms occur.
Thus, the XRD data confirmed the formation of both samples.
The performance comparative data of this work with the previously reported studies in AC/MnO2 Material.

Secondly, the bending strength of the panel structures was compared with the plain sheet steels to estimate the possibilities for weight reduction.
For example, in transportation business, the weight-reduction is directly utilized as increased payload or reduced operating costs.
The experimentally measured force versus displacement during three-point bending was recorded and compared with the simulation data.
(a) bending moment - displacement curves and (b) weight reduction estimation.
Results were compared against a conventional steel sheet, and approximations of weight reductions were made.

Data.
The land use data used in this study are from the Chinese Academy of Sciences.
uri=cn.csdb.soil, and the resolution of the data is 2km×2km.
The observed runoff data at hydrological stations are from 2006 to 2007, while the data at rainfall stations and meteorological stations are from 1961 to 2009.
Limited to the data available, the hydrological model is just validated using the observed runoff data of 2 years, although the validation results is good, more observed data including long series of runoff, evapotranspiration and groundwater table should be collected for more reasonable and comprehensive validation.
