Meanwhile, the slump of concrete could be controlled by addition of water reduction agent as far as it did not bleed

As the rough set theory can fully reflect the objectivity of the data, without providing any prior knowledge other than the data information, many scholars have studied the weight determination method based on rough set theory.
Knowledge Reduction.
Knowledge reduction is the core of rough set theory.
To calculate the attribute importance of indicators in above procedure, the discrete data processing, the selection of discrete values refer to reference 5, the discrete data table is shown in table 2; then the simplified data table is shown in table 3.
Rough sets: theoretical aspects of reasoning about data.

Experimental data for multiple cracking are analyzed showing that linear approximation of crack density versus applied strain may have sufficient accuracy.
The properties reduction with increasing crack density is linear.
According to Fig. 2 the shear modulus reduction slope is identical for CF/EP and GF/EP composites.
Fig 3. presents experimental data on cracking in CF/EP cross ply laminates.
The effective stiffness reduction in (0/903)s laminate, see Fig. 4, is much faster even if the crack density is lower.

The performance of the system was verified through experiments where it acted as a component of a vibration reduction system.
The damper and the generator are the key components of a developed vibration reduction system with energy harvesting.
Description of the system Underlying the prototype of the conditioning system are the research data summarised in [1].
The microcontroller block, incorporating a PIC16LF1827 chip, generates steering signals to analogue relays: q (AS_C), qGB (AS_GB) and qBC (AS_BC) and transmits the measurement data to the computer via a RS232 interface.
Summary The paper briefly outlines the operating principles of the system for conditioning signals from an electromagnetic generator that are used to power supply an MR damper and summarises the laboratory test data.

The input signal shows the original data for MP1 and MP2, characterized by significant multipath effects.

In the meantime, there have been fewer studies on sediment-reduction mechanism on the earth road.
As a result, it would show that the sediment-reduction mechanism of herbaceous plants on the earth road thus laying down a foundation for setting up sediment-reduction models for plant-growing road.

It can be seen from Table 4 that compared with the sediment reductions on the bare earth road there were remarkable sediment reductions as high as 76% on the plant-growing roads, which is very similar to the research results obtained by Grace (2000).
It follows that planted on earth-road surface, herbaceous plants are capable of water and soil conservation but the sediment reductions were remarkably higher than runoff reductions on the plant-growing roads.

In practice, the measured response data are mixed with inevitable input and output random noise, which causes inequality in the equation of motion and thus ill-conditioning of the inverse problem, distorting the identified stiffness and damping matrices.
In fact, in this method of noise reduction, the part of U(ω) which is almost noise-free is saved.
Comparison of the identified value with the actual damping value shows a substantial reduction in the error.

We compare the experimental data provided by EBSD at the early stages of abnormal grain growth where the first nuclei become distinguishable with the existing theories on secondary recrystallization of ferritic steels.
The plate was cold rolled up to 90% reduction and annealed in vacuum from 200oC up to 800oC for 1 h.
These features repeat themselves for the other two reductions, except by the corresponding volume fractions and onset temperatures.
As a general comment, by increasing the cold rolling reduction, the textures become stronger.
Summary (1) None of the existing theories of AGG in silicon steels are able to explain our experimental data in an indisputable manner.

In view of this, when processing the economic data, the data completeness should be ensured, the internal differences not destroyed, the hierarchical relationships highlighted and the dynamic development trend of the data focused.
Secondly, it uses the principal component analysis to realize the dimension reduction of the indicators, eliminate the data overlapping information and re-examine the index weight so as to make the indicator system level and weight clear.
Dimensionless data processing Economic system index data often belongs to different dimensions.
Let be the original data matrix， be the dimensionless processing of a data matrix, where .
Because larger data yield more stable communication, then 3.

Quality control tools are the means for Collecting data, analysing data, identifying root causes and obtaining the results.
It helps to categorize data.
Histogram is graphical representation of numeric data used to shows how often each different value in a set of data occurs.
Histogram is used to determine shape of data set.
Histogram works best when the amount of data is less but when there is huge data we go for Pareto chart as Pareto chart also arrange data in descending order.
