First, the energy consumption reduction effects based on the insulation performance of the developed insulator have been analyzed.
The energy reduction effect has been analyzed under the conditions as shown on Table 1, and the economic efficiency and carbon dioxide reduction effect has been analyzed during operation, based on the analyzed reduction effect.
Basic data regarding the possible range of unit cost has been used, when the unit sale price of the developed insulation plate was not yet calculated [7].
Conclusion The results of analyzing the energy consumption reduction effect as above, displayed a heating load reduction of 7.3% with the application of the developed insulation panel that has the same width as regulated by architectural standards.
However, only a reduction in carbon dioxide emissions occurred in the material production phase for Case 3, and there was no carbon reduction during operation.

Abstract.
The novel process control mechanism enables a 50% reduction in chemical consumption while achieving an at least equivalent TiN etch uniformity.
The TiN etch rates used are based on published temperature dependence data for an industry typical TiN material [6].
The achieved result for the chemical consumption reduction in this model was >50% while the etch uniformity stayed approximately the same (see summary of key data in Table I).
Alignment of experimental data (grey) with the modeled temperature profile (black) theoretically required for a 50% chemical cost saving on a TiN etch process (st.dev. <0.5°C).

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 system which adopted Delphi dynamic data binding technology and used Access as database was developed by Delphi7.0 visual tools.
According to the measured data in document[6], the initial proposal value for the settlement trough width parameter caused by underground excavation in parts of China was summarized and proposed.
Based on the model establishment and dynamic data binding used in Delphi technique, the visual operation results can be demonstrated to after obtaining the basic data.
Data Lots of date binding control is used in the system to realize the rapid data updates.
According to the basic properties of the region, building and distance reduction factor, the reduction factor values H and S is inputted into the system to calculate the extent of damage classification.

Pawlak’s rough set theory, as a supervised learning model, is only applicable for discrete data.
For the convenience of description, we introduce some new symbols as follows: In general, the partially labeled data are expressed as , where refers to the labeled data set, is the unlabeled data set, and the range of decision attribute.
The data that are transformed by is expressed as .
In the partially labeled data, the decision table which is composed by all correctly unlabeled data is represented as.
It’s helpful for classification in ship data.

Even though the link between air pollution and Covid-19 lockdown measures can be mapped by every available data on gaseous pollutant emissions from transportation and industrial engines, but this reduction can never be more sustainable in creating a greener environment.

In accordance with the XRD data, the unmodified sample matrix is austenite (γ- (Fe,C) phase) having a FCC lattice with an Fm3m spatial group.
The unmodified sample: а – optical metallography; b – histogram of grain size distribution As shown by the data of SEM there are nonmetallic inclusions inside the grains and along their boundaries observed in all unmodified samples at the horizontal section at a distance 10–15 mm off the lower boss surface (Fig. 2 а-c).
This is proved by the XRD data.
It was established by the XRD data that the introduction of the MM based on ultrafine particles of refractory metal oxides and cryolite did not lead to the formation of new phases.
It was established that the grain size reduction and decrease in the amount of nonmetallic inclusions results in the insignificant enhancement of mechanical properties.

The extraction data for the system macaúba oil + free fatty acids + ethanol + water was determined for oil:solvent mass ratios 1:1.
For equilibrium data comparison, the extraction and cooling processes was carried out for 24 hours.
From the statistical data in Pareto chart (Fig. 1) it can be concluded that temperature and water content in ethanol has not a significant effect (p < 0.05) in the FFA reduction.
As the stages number increased of 1 to 3, the FFA reduction increased of 20 to 60% (Fig. 3).
According literature data, the solubility of TAG in ethanol increases in direct proportion to their FFA contents [10].

Introduction
In the fourth generation (4G) wireless communication, Orthogonal Frequency Division Multiplexing is one of the standard multi-carrier attractive technology, here a high data rate stream is split into a number of lower data rate streams that are simultaneously transmitted over a number of sub carriers.
The average signal power of input data sequence is the peak value of the auto correlation [4-7,12].
When the DCT is applied to the data sequence, many zero elements appear in the DCT transformed sequence but the sequence structure is not changed.
In this system, the adjacent two input data symbols are jointly mapped to a single sub-carrier, and then the frequency separation between the sub-carrier is increased.
After DCT transformed , the peak power of input data sequence X DCT is expressed as (19) After DCT many data sequence values are very small and some zero elements will be appear in the DCT transformed sequence.
