The energy before the improvement is expressed as (3) where Epre is energy before the improvement (kWh/year) Ppre is power before the improvement dt is 15 minutes interval of data record period (min) r is date of data record (Monday – Sunday) n is the number of days of data record The level of energy consumption after the adjustment can be calculated as (4) where Epost is energy after the improvement (kWh/year) Ppost is power after the improvement dt is 15 minutes interval of data record period (min) r is date of data record (Monday – Sunday) n is the number of days of data record Research Methodology In the procedure, energy was measured before and after the improvement of voltage level at four electrical control panels which are lighting control panel, motor control panel, heating control panel, and chiller control panel respectively.
The data acquisition was uninterruptedly recorded every 15 minutes within 7 days by considering energy consumption in 24 hours [6] in an industry.
In spite of those dissimilarities, this paper shows results from the both techniques in order to be useful in selecting data as alternative sources for energy conservation.

In this purpose, the data acquisition of all recorded data would be further analyzed according to the following information.

They may use Hive, Pig, ZooKeeper, Cascading and other module to solve serious problems in TB/PB magnitude data storage, extensible computing, and data analysis processing, and so on.
Experiment proved that when the data volume increases, the memory overflow of MR_CD and MR_DD will occur.
As to the above deficit, scientific reference [6] and reference [7] have made equivalent improvement, the idea is to add in a Combiner prior to Map output, used to reduce the local data reduction, similar to the local Reduce function, reducing data transmission in the network and I/O reading in the disk.
Map scans every recorded sectional K candidate item sets in data subgroups, each candidate item set counted as 1, then output the intermediate result by Combiner reduction.
Then we will use the present existing TB/PB grade gigantic data sets to undertake simulated test to this algorithm.

The thermodynamic data of the compounds in the article are from the literature[11].
The required initial temperature of the reduction reaction can be decreased to avoid the unfavourable influence on the nitridation process.
So it is necessary to select appropriate additives for the reduction reaction.
The mechanism of the effects of additives on the carbothermal reduction nitriding to synthesize the vanadium nitride is still unclear.

A few formulae, commonly used to predict the coefficient of friction from forward slip measurements of a rolling process, have been evaluated according to forward slip measurements and coefficient of friction data.
At the same time, the contact arc increase due to the large reduction and the roll flattening.
It is this variation that poses severe difficulties for researchers to secure reproducible forward slip data and that perhaps well explains the scatter found in many forward slip measurements.

It is believed that this variation poses severe difficulties for researchers to secure reproducible forward slip data.

Then the concepts of synchronization edge, process, synchronization process, base process, process tree, data type and trace-set of types is given.
Process model and data model are two essential aspects in workflow management system.

The experimental results indicated that the in-situ carbon dioxide generation technology could be used to produce enough carbon dioxide and get good efficiencies of oil expansion, reduction of viscosity and enhancement of oil displacement.
This can generate gas mixtures can be given preferential access to the high permeability layers in the formation of a chemical exothermic reaction of CO2, the expansion of crude oil viscosity reduction.

In this paper, we propose a new method of data repairing based on Anatomical CAD.
Generally, Reverse Engineering refers to the process of reconstructing CAD models from existing parts, which consists of data acquisition, data pre-processing, incomplete data repairing and CAD modeling [1].
When capturing data, measured data of a product can be incomplete because of the inaccessibility or invisibility of the surfaces for the measure tools, which need to take data post-processing and repair the model.

After operations of the point cloud Noise Reduction, Sub Sample, and Mesh Data, an STL file is obtained, as shown in Fig. 4.

In addition, the three types of shelters are functional uniform that is urban green space shelter for emergency shelter also can be used for temporary and long-term shelters if possible. 2.3 Landscape pattern index and disaster reduction function of greenbelt of urban The landscape pattern is a set of landscape elements, which are arranged from a series of different sizes and different shapes landscape elements [6, 7].
The performance of landscape patterns determine the various ecological processes, as well as determine effective green space for disaster reduction and shelter (Table 1).

Dimensionality reduction is the mapping of high-dimensional data into some representation of lower dimensionality.
We apply GPLVM method for dimensionality reduction on the data set which is in high-dimensional form, and then we evaluate the quality of the resulting low-dimensional data representation by comparing the results attained to those we got when using intrinsic dimensionality estimation techniques, and lastly compare the performances of GPLVM and PCA on the same data set.
The data set consists of 53 data points with a dimensionality of 87 features.
Now, our data set has been successfully downsized using the above illustrated dimensionality reduction techniques, the next step is to make use of this outcome for effective and fast clustering.
Fig. 3 shows the resulting data clusters.
