Because the static equation before and after the growth of venation cell is both satisfied, and the global stiffness matrix is increased, the global displacement is decreased, we can get
(8)
where u0 is the global displacement before the growth of venation cell, Δu is the reduction of displacement vector.
That is, the reduction of total strain energy can be measured by the strain energy of the growing beam element equally by the last FE result.
The material constants are referenced as the data measured in [11]: E = 6 Mpa and Poisson’s ratio v = 0.365.
Strain energy proportion before and after mainvein growth is Einit / Eopt = 1.188 which is smaller than the data in [12], because the rib there lay in the two sides of plate.
The mainveins grow as to minimize the total strain energy and subveins are generated by the reduction of shear stress.

A specific database has been constructed for easily managing the whole data.
The Italian seismic catalogues have very poor quality and incomplete data for these events associated with the Montello thrust, leaving room for different interpretations as, for example, the possibility that these earthquakes were generated by nearby secondary structures.
The out-of-plane mechanism of masonry façades implies the reduction of the viable connection infrastructures’ width, influencing road functionality during the immediate post-earthquake emergency operations.
The procedure is able to evaluate the network link functionality reductions caused by building damages, through the estimation of the residual road width.
The procedure allows to identify possible criticalities in relation to specific earthquake scenarios, providing useful information to Institutions and organizations with civil protection tasks and giving useful elements for the identification of mitigation interventions to be carried out for seismic risk reduction in historical urban centers.

However the laser system has many subjects to be solved, the
examination is starting in several western countries with the emphasis on substantial reduction of
weight and multipurpose application in space [5].
Solid laser system is the base of this modeling, based on the small-scale experimental data of the Institute for Laser Technology (ILT).
The oxidation reduction potential of H2S is 1/4 lower than water.
Adaptation for structures aimed at the epoch-making reduction of weight is as follows, huge heat exchanger, huge heat pump, huge truss etc.
At last, I wish to acknowledge every person offered data for preparation of this paper.

Geological disaster hazards are extremely serious, a great loss, according to the latest natural disasters statistics of the United Nations International Strategy for Disaster Reduction (UNISDR) and the Disaster Research on the Epidemiology Center (CRED) released in Geneva on January 28, 2010, between the years 2000-2009 ,3852 disaster events occurred in the world between the years 2000-2009, more than 78 million people were killed, and all kinds of material losses of up to $ 960 billion, which the earthquake led to the casualties up to the first major disaster threat.
Investigation appraisal method bases on the survey, according to some intrinsic link or trends between the disaster data, to infer the loss of the year which is no quantitative data.
Geological Disasters Indirect Economic Loss Assessment The indirect economic geological disasters loss includes stop and reduction production loss and associated loss.
Stop and reduction production losses can not be quickly restored production to get rid of the post-disaster economic "shock" state [2]; associated loss refers to it can’t quickly adjust the layout and get rid of the production capacity disequilibrium [2] which caused by disasters.

Peraha-Videa international poential of chilopsis linear is for gold phytomining: Using XAS to determine gold reduction and nanoparticle formation within plant tissues[J].
Data processing and mapping.
SPSS17.0 and Excel 2003 were used in the study to analyze the experimental data.
Thus obtained that, when the incineration temperature was set at 400°C, the samples had a larger weight loss, lesser amount of arsenic volatilization; comply with the requirement of treatment and postproduction:"quality reduction, arsenic volatilization harmless".
But at the mean time, it will also reduce the reduction rate of the biomass and increase the quality of residual ash.

The recorded and calculated data of the test series are evaluated in a software application for data analysis and graphical representation and then displayed graphically.
By reducing the curing pressure from 5 bar to 1 bar, it is possible to save 87 kWh of energy, which corresponds to a reduction of 36 %.
Fig. 7: Energy saving potential by reducing the curing temperature It can be clearly seen that at a curing pressure of 1 bar a reduction of 71 % in energy consumption can be achieved by lowering the curing temperature from 180 °C to 80 °C.
However, since low-curing matrix systems require longer holding phases, the advantage lies in the reduction of the temperature and longer holding phases.

The results obtained by these electrochemical methods and the application of a complex body specimens may provide available data for evaluating the corrosion properties of the embedded steel bars.
Furthermore, the complex body specimen may serve as good reference data in the design and for successful maintenance of the concrete structures in marine environments.
Generally, the cathodic polarization curve measured in neutral seawater solution would exhibit nearly concentration polarization caused by reduction reaction of dissolved oxygen(O2 + 2H2O+ 4e→4OH-), thus, diffusion limiting current density would vary with thickness of diffusion layer.
However, dissolved oxygen, water and chloride ion penetrate continuously from surface of the specimen to embedded steel bar, and anodic oxidation reaction (Fe → Fe2++ 2e)by chloride ion and reduction reaction(O2 + 2H2O+ 4e→4OH-)by water and dissolved oxygen would happen on the surface of the embedded steel bar during immersed for long years.
However, during drawing of the cathodic polarization curve, the reduction reaction(O2 + 2H2O+ 4e→4OH-)by water and dissolved oxygen would only happen on the surface of the embedded steel bar.

The linking between C# and MATLAB is done using COM automation server and the data in the client C# program passes it to MATLAB and vice versa.
The Interface Free Controller Cards (IFC) is a set of IFC controllers used in the project to exchange the sensing and actuating data.
The brush motor card (IFC-BH02) is a slave card and it is used to supply power and getting data from encoder.
The DIP input data is coming from IFC-BL02.
IFC cards were used as the embedded controller to transfer and receive the data between the electronic and mechanical parts of the platform.

Initial Rv: 25 % Rv: 40 % Rv: 60 %
Fig.4 Progressive deformation patterns in equal-biaxial compression
Rv: Reduction in volume
Testing Conditions of 4-point Impact Bending Test
The mechanical property of the biaxially compressed wood is evaluated by the 4-point bending test as shown in Fig.5.
The mean Young’s modulus was estimated under the assumption of linear elasticity using the data both in loading and unloading.
The Young’s modulus of compressed wood with 64 % reduction in volume was more than 4 time of the uncompressed one under impact and quasi-static test conditions.

For the composite containing voids, the spatial autocorrelation function and statistical parameters are used to describe the large scale heterogeneity from the composite matrix and the small scale heterogeneities of elastic fluctuations from random voids, the values of which are determined by statistical data from microscopic observations of voids morphology.
For instance, for every 1% increase of void volume fraction, the reported inter-laminar shear strength reduction of 5–15% was reported in different works [18].
