The observed reductions in permeability are comparable to those produced by traditional methods such as cement and bentonite grouting.
Assessment of Permeability Reduction Due to Bio-Clogging Figure 3 presents the progression of permeability from the Test BC series.
Simultaneously, data from the BC’ series revealed that dextran concentrations began to increase exponentially between days 5 and 15, corresponding to the active growth phase of the bacterial population.
This two-order-of-magnitude reduction highlights the effectiveness of microbial activity in obstructing pore connectivity.

Table 1 Initial sample collection of 15 data No.
According to the rule set after reduction, we get 8 data.
In order to validate the need of attribute reduction, we let the reduction set R = {a2, a6, a7}, and pick up 150 data as training samples, 70 data as test data.
It toke fully advantage of data reduction features of rough set and excellent sample classification capabilities and high computing precision characteristics of SVM.

This model provides a relative simple description of hysteresis without needing a large amount of data in a lookup table.
The Bouc-Wen hysteresis model for an active suction block was determined using experimental data from ramp input increasing (0 - 10V) and decreasing (10 - 0V) by voltage rate 1 V/s major loop hysteresis curve sampled at 1 kHz.
The identified hysteresis loops initially appears to fit well to the measured data.
This suggests a 93.28% reduction in major hysteresis loop area.
This larger amount of data allows more accuracy in hysteresis model result.

Based on the comparative analysis on the low-noise road surface, noise reduction green belts, noise barriers and other noise reduction methods, the sound barrier is put forward as an important method for reducing the city road traffic noise.
The noise and vibration test and analysis system mainly includes multi-channel data recording instrument and front end, HPS IV Digital Playback System and so on.
Fig. 2 Data recording instrument and front end Fig. 3 HPSIV digital playback system Test point arrangement.
The result reflects the obvious noise reduction effect of the sound barrier.
The sound barrier has better noise reduction effect in the high frequency range.

Principle component of raw data is extracted by using improved KPCA.
Through Transmission Control Protocol, these data is transferred from Microprocessor to PC.PC process these data and determine the category of the motion.
When an unknown motion sequence is input, processing raw data with PC.
Dimension Reduction of Motion Data Vpnik etc present the learning method of SVM according to statistical learning theory and introduce the concept of kernel space.
It can map the linearly non-separable data residing in low dimension to high dimension and make data linearly separable.

The reduction jar, as a core device of the reduction furnace, has many disadvantages, such as easy to wear, short service life, and high cost accounting for about 25% of the total cost[4].
The thermodynamic data of the reactants and the resultants in Eq. 1 can be referred in relative data manual[21].

Methodology The methodology is divided into several stages includes preliminary stage of study, data collection and analysis, discussions and conclusion.
The review from the PLUS Expressway record on energy consumption for the energy usage had been carried out.The data collection is in the form of questionnaire survey.
All the data from questionnaire survey is analysed using SPSS (Statistical Package for the Social Sciences) software.
From the data gathered, the potential retrofits to reduce energy consumption at the RSAs have been identified.

In this study, the green synthesis using chemical reduction of Premna serratifolia linn leaf extract was used to produce ZnO nanoparticles.
One of the environmentally friendly methods is chemical reduction using plant extracts in the fabrication process.
These flavonoid and alkaloid compounds can provide a role as a bioreductor in the synthesis of ZnO via chemical reduction.
The XRD data was compared with The Joint Committee on Powder Diffraction Standards (JCPDS) card for hexagonal wurtzite ZnO (JCPDS 036-1451) to identify the crystalline phases present in the samples.
The analysis of the XRD data from the samples synthesized at different calcination temperatures indicates that the obtained peaks match well with the characteristic peaks of hexagonal wurtzite ZnO.

The storage and management of solar energy data are of good performance.
In the solar energy engineering, it is often to store the acquisition data, query and update the solar energy data.
