The incorporation of fibers did not cause any change in the amount of water added to the mortar, however there was a slight reduction in the diameter obtained for the mortars doped with microcapsules A and B.
The introduction of these materials had as main objective the reduction and control of shrinkage.
The transducers are connected to a data acquisition system, where the values of shrinkage of mortars in time were registered.
The addition of 40% gypsum allows a reduction in the shrinkage of about 60%.
Moreover, the reduction of shrinkage observed with the addition of gypsum, is connected to the expansion which occurs with its hydration.

We get the critical value “a” and “b” of carbon management performance and economic and social performance by analytical calculation of the indicator data.
Two general P indicators of the sample observation data has extracted.
is determined by the data of the discriminant matrix.
And we can get discriminant value B in the same way after getting the data of economic and social performance of the enterprise.

Data collection and analysis
Plant growth was measured as plant height, stem diameter and dry matter.
Data on plant height and stem diameter was collected every week.
Most of this data was collected at the final harvest.
We are also grateful toDesmond Ofosu, ChantallKwizera, Mark Boateng,KwakuAdjei and the laboratory group for their assistance in the analysis of the samples and data handling for providing excellent facilities for conducting the field experiment.

The undesirable changes in liner thickness have explicit effect on the liner density which is translated into reduction in energy absorbing potential.
For the experimental test, a drop test machine Instron Dynatup 9250HV, a standard headform size M equipped with triaxial accelerometer, a hemispherical anvil and a data acquisition system were employed (Figure 1).
Among the data recorded were the headform centre of gravity peak resultant acceleration against time (in terms of gravitational acceleration, g), the impact speed and components deformation/crack status.
Nevertheless, the test proceeded to gauge the effect of these cracks on the headform acceleration data.
There was limited data to relate the result with the shelving conditions.

During earthworks designing can be used these new data.
The basic documentation for the elaboration of the project documentation is the quality geodetic data, including the elevation data of the locality.
Because a designer needs for designing data from vast space (square kilometers), it is appropriate to use this elevation data.
But there are many other areas of use of these elevation data.
This solution leads to a reduction in their budget.

This paper presents the effect of nitrogen interaction on the reduction of austenite grain growth during vacuum carburizing and on the mechanical properties (fatigue strength, impact resistance) of the layer treated in this way in relation to conventional carburizing methods.
Considering economical reasons, the most effective carburizing process requires a maximal reduction in its duration, especially when the point is to obtain layers with greater thicknesses.
Fig. 1 a) Structure of surface layer of steel 16MnCr5 after the low pressure carburizing (LPC) in temperature 920°C and b) after the low pressure carburizing in temperature 1000°C with the prenitriding - PreNitLPC® These tests confirm the effect of nitrogen on the reduction in the grain size of the primary austenite in the carburizing process.
Taking into account cost data and the furnace processing capacities, the unit costs of the carburization of a 1 kg charge were determined and compared.

Same as the conclusion got from export coefficient model, the nitrate nitrogen concentration distribution map drawn by the field survey data indicated that planting was the main nitrogen load source of Damintun town.
The amount of soil chemical fertilizer and farmyard manure used in this area was calculated by a field investigation combined with the data of "Shenyang Rural Statistical Yearbook".
Thus combined with those data the cattle, pig, sheep and poultry excrement output coefficients in Damintun town were 10.21 kg·ca·a-1, 0.74 kg·ca·a-1, 0.40 kg·ca·a-1 and 0.04 kg·ca·a-1 respectively.
So rational fertilization is the key of reduction nitrogen pollution load.
Rational fertilization is the main way to reduction nitrogen pollution load in Damintun town.

An excellent agreement with measured data is obtained using this model, making it more suitable for predictive device simulation using TCAD tools.
We present a revised channel mobility model that is well calibrated and shows an excellent match with the available measured data from lateral 4H-SiC MOSFETs.
We performed an extensive recalibration of the SR and SP model parameters against measured hardware data, which leads to a different set of parameters developed for 4H-SiC.
As evident from these results, we obtain an excellent match with the measured data across a wide range of P-well doping concentrations and across the multiple temperatures (ranging between 25-175 °C).

The software of the system introduces Producer/Consumer pattern to improve data sharing and buffered communication between data collecting and data storage processes, by this means, data missing and iteration are avoided, although these two processes run at different rates.
The data management module answers for data storage.
There are two loops representing different process, one performs data acquisition and the other is responsible for saving them in data file.
The data acquisition process acts as the producer and the data storage acts the consumer.
It ensures data transmission process against data missing.
