Including preparation activities, training intermittent time, recovery training, relaxation method, and pre competition training and other rational assessment, can also include the assessment weight reduction or gain weight training and other non-improved special skills training methods and means
The conceptual structure is a common basis of all kinds of data model, the data model is more than the machine-independent, more abstract, and thus more stable.
Logical Structure Design Results of logical database design is not unique, in order to further improve the performance of database application system, should also be appropriate to modify the structure of the data model to improve query speed [6,7].

The utility industry across the world is trying to address numerous challenges that occur in exsiting electrical grid, including generation diversification, optimal deployment of expensive assets, demand response, energy conservation, and reduction of the industry’s overall carbon footprint.
The control center uses computer-based monitoring and control system, called Supervisory Control and Data Acquisition (SCADA) system.
They also connect local Data Aggregation Nodes (DANs) to the core network through the backhaul network.
The smart meter collects data from smart devices and invokes certain actions depending on the information it retrieves from the grid.

It means that the usage of products with thinning we can get a reduction of the volume of material needed in production process of amount . (7) Additionally, the longitudinal microchannels in the wall (in number of , each of them has circular cross section with radius ) reduce the cross sectional area of the channel of the value .
Empirical data is presented in the table below.
Specific data of investigated ducts Typ of sample Wall thinning, mm Force Q in 3% displacement, N Stiffness value, kN/m2 Duct sample 4 5,1 500,28 17,49 Duct sample 3 2,6 200,16 7,21 Duct sample 2 2,1 168,35 6,07 Duct sample 1 1,1 16,96 0,61 Using the linear regression based on the given data we obtain the form of the regression equation . (9) In the specific case, this means that for a given value of the wall thinning the force can be calculated from (9).

In order to obtain experimental data on the bearing capacity, crack resistance and deformation, 24 prototypes were manufactured and tested.
In addition, to expand the experimental data, "numerical experiments" were carried out, which allowed to perform a joint analysis of its results and experimental data to assess the degree of influence of various factors on the bearing capacity, crack resistance and deformability of compressed concrete elements with an increased protective concrete cover and without transverse reinforcement [8-11].
However, the degree of reduction in the bearing capacity depends on the percentage of reinforcement and the thickness of the protective concrete cover.

Load and displacement data was recorded automatically by the Instron testing system under the displacement control mode.
The elongation data of the extensometer was recorded by a strain gage measuring system.
Joint damage can be indicated through joint stiffness reduction or hole elongation.
From the data presented in this paper, the following results are concluded: (1) The ultimate bearing stress of the composite joint is around 745MPa

One of the effective ways to increase the fuel efficiency is the weight reduction of these transportation systems.
The purpose of this report is to investigate the research trends of lightweight alloy welding technologies including the high quality advanced welding technology such as laser beam welding, friction stir welding, and laser-arc hybrid welding process which is based on the published research works in the welding and/or joining technology of aluminum alloys and magnesium alloys with high specific strength and low density, obtained from the KISTI's database, COMPENDEX DATA BASE SYSTEM, and also deals with the detailed background data of the welding process technology of the lightweight alloy.
COMPENDEX DATA BASE SYSTEM covers the trend of the volume of annually published papers concerning welding technology of lightweight alloys, including the contents of those papers which were mainly experimental and theoretical.

Data of 2D seismic exploration show that the structure of this block is simple and the general form is an anticlinorium trending near NS direction.
According to the drilling data of this block, the coal beds of Shanxi formation and Taiyuan formation in southern Qinshui Basin are six to eleven layers.
(Table 1) The high vitrinite content reflects reduction sedimentary environment and this is very good at forming complex coal reservoir blended of fractures and matrix pores.
The correct measurement and explaination of experimental data is very important to understand and predict the gas producing performance of coal reservoirs.

Agglomeration of particles in specifically designed machines is one of the ways to obtain such reduction.
Compressive strains of a brittle porous material vs. its relative strain [6] The literature does not provide sufficient data concerning the mechanical properties of agglomerated carbon dioxide.
The sample data are presented in Table 2.1.
For data acquisition during the test the Test Work 4.0 software program was used with the frequency of acquisition pre-set at 10 Hz.
