The harmonic motion of the actuator was controlled by Instron system, while data acquisition was done by multi-channel system „MCG Plus” of Hottinger.
The material data of plexiglass are as follows: density r = 1318.7kg/m3 and Young modulus E = 4.51 GPa.
Beam with two stiffness reductions.
α1 α2 α3 Real stiffness reduction 0.85 0.70 0.55 Detected stiffness reduction 0.86 0.67 0.54 Fig. 5.
For the three segment stiffness loss, beam reconstructions gave the best results using only rotational vibration data (Table 1).

The data error between the calculated result and the original experiment one is less than 5%, so the calculation precision meets the requirements.
Especially for the latter, if used properly, can be obtained the data by computer simulation which are usually only need to use complicated and expensive measurement.
In which, Calculate / animation parameter is single point calculation, Data storage space is 1440deg, The calculation time step control is 30ms, Output data between is 5CA °, The calculated maximum regional is 14400CA °, Hybrid external mixing style, Gasoline calorific value is 43500KJ/kg, theoretical air fuel ratio is 14.7, 燃烧模型韦伯模型 The combustion model is Weibull model, and the Webb constant is 6.5.
As can be seen, the calculation results error does not exceed 5% with test data, simulation results and test results are good agreement, indicating that this model can be used for parameter optimization calculation of the engine.
shut angle and small exhaust advance angle makes its power and torque reduction.

The possibility of the reduction of the maximum and average error by means of the little changing of the value of the arc’s lateral deformation for a fixed traveling time is shown in this article.
There are the reserves to reduce the errors using the sigmoidal functions of specifying load’s path of motion with PID-regulators, which provide reduction of high-frequency load’s oscillations [4].
Fig. 1) the path of motion of point of suspension and cargo for raw data sx=5 m (sx k=sx); TP=25 s; l = 12 m; lx = 10 m, with a gradual increase in scaling and examples of the shortest distance li short determination is shown.
In Fig. 4, b the graphs of two separate functional dependencies Δmax(sx k) and Λ(sx k) for initial data sx=5 m; TP=25 s; l=12 m; lx=10 m were shown.
The parameters of input data [sx; TP; l; lx] in each experiment received the fixed values sx=5 m; TP=25 s; l=12 m; lx=10 m, with the exception of cases when any one of these parameters was being changed.

With this software we can open scan data from any scanner (mesh or point cloud files), then convert it into a surface or solid model.
So by increasing the number of points will increase the profile accuracy, but also will increase the processing time of data.
Functional model which can be designed For a better understanding of scanned file transformation, the procedure was split into three main steps: open data, prepare data and convert to solid (Table1).
Open or scan Data Open Cloud Point II.
Prepare Data Run Mesh Preparation to: a.

The results show that the higher annealing temperature, the larger oxidation/reduction peak separation.
The phase formation and transition temperatures observed in this work are in a good agreement with the literature data [31,32].
Their reduction- oxidation peak separation was approximately 0.273V and 0.697V, respectively.
However, reduction-oxidation peak separation of TNT/500ºC electrodes was approximately 1.905V.
The results of cyclic voltammetric tests show that a pair of oxidation/reduction peaks was observed and the higher annealing temperature, the larger oxidation/reduction peak separation.

M. showed that heat treatment modified the chemical composition of the wood, resulting in reduction of water absorption by the cell walls due to the reduction of hydroxyl groups [5].
As a result of processing of experimental data the dependence of the equilibrium moisture content of wood by temperature treatment was obtained (Fig. 2.).
Based on these data it is concluded that the increase of temperature of wood treatment leads to the release of the cavities of the vessels, causing them to become hollow.
As a result of the investigations of thermally modified oak wood the data about the content of extractives soluble in water and depending on temperature processing of timber were obtained (Fig. 6).
In addition there is a significant reduction in equilibrium moisture content of wood with increasing temperature of treatment.

However, when the percentage of residue added to the mixture increases to 35%, a large reduction in apparent density is observed.
This sharp reduction is reflected in all the volumetric parameters and may be a result of changes in the granulometry of the mixture at this percentage.
However, the mixtures containing 35% and 40% of residue showed a reduction in stability.
This behavior does not agree with the data obtained for Marshall stability.
The addition of residue to the mixtures studied caused an increase in stability and a reduction in tensile strength.

One additional goal of the study is to obtain a consistent reference data basis - by using the developed tools to analyze existing aircraft - prior to use these tools in new designs with the features of low speed, low wing loading and low power.
Regarding this, an overall picture of the flight power reduction, since the first successful aircraft designs is the point of interest.
Airfoil data from [17] are taken as additional information.
The tool to obtain propeller thrust and power coefficients Ct and Cp is based on the “blade element” and the “momentum change” theories [16]; the main input are the geometric data and presumed airfoil shapes of each aircraft.
It can be noticed through this figure the reduction in the drag coefficient CD from 1890-1910 aircraft to Condor and Solar Challenger.

The surfaces were sputtered by Ar ion sputtering for 5 nm before the data collection in order to eliminate surface contaminants.
The data of hardness and elastic modulus were the average values from three repeated indentation tests.
When MoDTC is added, both of the average frictions are declined because of the friction reduction property of MoDTC.
So this lubricating system has both excellent friction reduction and wear resistant properties.
So the Mo film has excellent wear resistant property and good friction reduction property under ZDDP lubrication.
