The basic idea of exponential smoothing method is to calculate adaptive learning coefficient of the model by the minimum deviation between actual data and calculated data.
In this way the difference between actual data and calculated data will decrease significantly, and the presetting precision will improve accordingly.
Where actual data calculation step is the most important.
There are three kinds of actual data, including measurement actual data, backward calculation actual data, and model calculation actual data.
Therefore, they are called backward calculation actual data.

The data was considered ineffective unless the site of the fracture or the initiation of cracks was within the gauge length of the dynamic extensometer.
Effect on the reduction of area of Fatigue damage The reduction of area is one of plasticity index of metal material.
Fig.6 shows the relationship between the reduction of area and the cycles.
Compared with the reduction of area under static load, the increase in reduction of area of specimens subjected to fatigue cycles is shown in Fig.7.
Fig.6 Relationship between the reduction of area and the cycles Fig.7 Increase in the reduction of area Summary (1)The test material exhibited cyclic hardening, which contributed to improve its bearing capacity under high cyclic loading

Subsequently, Fast Fourier Transform (FFT) was used to transform the vibration data from time to frequency domain.
Table 2 shows the highest percentage reduction was observed also in run number 1.
This reduction was due to the damping effect of the magnets on the vibratory motion of the tool.
The best chatter reduction is showed by the side magnet, SM (1500 Gauss) with 97.19% vibration reduction at the cutting speed of 125m/min, feed rate 0.16mm/rot, and depth of cut 2.21mm.
At the condition of 1 kHz, the highest percentage reduction is by the big magnet (BM), with 4500 Gauss at run number 1 with cutting speed 125m/min, feed rate 0.16mm/rot, and depth of cut 2.21mm, which is approximately 90% reduction. 4.

It also reduces inventory costs by allowing lower WIP (Work-In-Process) quantity at any given time with the streamlined process.Generally a popular and simple way of cycle time reduction is to reduce WIP.
Coefficient of Variation (CoV) In most situations where data is presented, the reported indicators represent an average of the data points.
However, averages give no information about the distribution of the data.
CoV is a good measure of variation: (3) CoV can be used for any data set, as long as there are enough data points, typically more than 30 to have statistical validity.
With easy access to arrival and departure rate data, the factories now have one more data tool, besides CT, to pinpoint flow issues through the process.

In this mode, the audience is not just simply as a map service users, more importantly, it's the provider of the data or information at the same time.
As the profound application of geographic mark services, the data volume provided by the receiver must be increasing exponentially.
On content analysis, the main form of annotation is the word or value of structured data.
If the present category is not detailed, it can be referred to other classification data for a fine classification. 3.2 Emplacement region based on Voronoi k-order Adjacency.

Therefore, the method could provide necessary support for quantitative use of HJ_1A HSI data.
Since the quality of HSI data products is poor and the random additive noise disturbance is serious.
The greater its value is, the more sparse of the wavelet representation in the noise reduction model.
Data processing and results analysis The experimental data is HJ_1A satellite HSI secondary product obtained on October 30, 2010, which is after radiometric calibration and system geometric correction.
Therefore, the method could provide necessary support for quantitative use of HJ_1A HSI data.

The validation process involves comparing the numerical results with test data from relevant literature.
Previous Test Data Was Used for Model Validation The punching shear resistance of flat slabs with openings in this research is based on experimental data conducted by A.
There is a reduction in ultimate load by about 14% compared with the control specimen.
There is a reduction in ultimate load by about 15% compared with the control specimen.
Results Discussion The model used for validation in this research is based on experimental data from previous research.

Moreover, the reduction amplitude of Fz and θ corresponding to the four cutting speed are about 11.0%, 10.9%, 10.8%, 7.6% and 17.5%, 15.4%, 13.1%, 6.6%, respectively.
Besides, the reduction amplitude of Fz and θ is closely related to the hydrogen content, the reduction amplitude is just maximum only for optimum hydrogen content.
Therefore, reduction of E after hydrogenation is adverse to reduce Fz and θ.
The μ value reaches minimum when w(H) are 0.26%, which can reduce θ thanks to reduction of friction heat between chip and rake face.
Besides, the reduction amplitude is closely related to the hydrogen content, and the reduction amplitude is just maximum one only for optimum hydrogen content.

Collecting basic data on the object (its space-planning decisions, technical condition, current level of resource consumption, financing sources of resource-saving solutions realization).
Comprehensive assessment of the efficiency various RSS realization 3.1 Resource unit This stage involves the calculation of the expected level of energy resources consumption by the building for each option and its comparison with the actual (current) data.
Collecting basic data about the object and formation of the project requirements Step 2.
To simplify the calculations of LLC it seems logical to apply the resource-technological models and data on operating costs in the similar objects. 3.4 Calculation of the integrated indicator of building’s sustainability Stage 3.4 involves the assessment of sustainability that the building achieves through the implementation of resource-saving solutions.
This stage involves the calculation of ratio of the project life cycle cost to the indicator of its sustainability LLC/Sust for each variant and the search for the minimum value from the received data.

The reduction was greater in green gram than common bean [11].
Monthly mean maximum temperature data for Sokoto was used for determining the monthly crop water requirement (CWR).
Much of the reduction in biomass of the canopy was due to reduced leaf area.
Even though the irrigation amount was halved, there was no significant reduction in yield due to 50%PRD treatment.
