The acquired data presents that the roughness exceeds the tolerance during the processing by tool made of H10F alloy later than by tool made of VK6 alloy.
Reduction of hard alloy grain is the main trend in structure changing.

Recently, micro-computed tomography has made it possible to obtain two-dimensional and three-dimensional data of trabecular microstructure without destruction of bone samples.
The microstructure showed deterioration in the osteoporosis group, as expressed by significant reduction in the bone volume, the bone volume fraction and the trabecular number and an increase in trabecular separation when compared with those of non-osteoporosis group.

By considering grain growth as a dissipative process that is driven by the reduction of the Gibbs free interface and junction energy a general grain evolution equation is derived that separates into nine types of possible growth kinetics.
Figure 2 (left) shows the GSDF Eq. (10) in comparison with numerical data resulting from Monte Carlo Potts model simulations of grain boundary energy-triple line mobility limited 3D grain growth in the scaling state [10].
Figure 3 (left) shows that Eq. (12) describes, for D = 3, the numerical data of large MC simulations of grain boundary energy-quadruple point mobility limited three dimensional grain growth in the scaling state very well [10].

Introduction
Marine grade alloys are extensively being used in high speed vessels such as patrol crafts, ferries and crew boats, where a reduction of the structural weight is critical to achieve higher speeds [1].
Holden et al. [11] who derived empirical formula for the propeller pulse load from full scale data.
Using the formula supplied by ABS and the vessel data [8] the propeller pulse load was calculated at multiple locations perpendicular to the vessels centreline (in plane with the propeller), at vessel speed of 18 knots.

We find that the clean surfaces are semiconducting with surface states
in good agreement with experimental data.
Experimentally, Hollering et al. find an even weaker reduction of the intralayer spacing z12 of 16%.
Nevertheless, the surface states and the observed resonances are in good agreement with experimental data.

This model was tested on the crime data of India.
During the early days of technological development, Data mining arose as a powerful method for extracting usable information as data from enormous datasets to determine the relations between the data and its features.
Decision trees are built associated with the selected data points.
Data cleaning is done by filtering out the missing values, duplicate data, and error values from the dataset.

The obtained electrical properties confirmed the suitability of the surface-coating to provide simultaneous oxidation-reduction driven reactions under the photoinduced catalytic activity.
(Pantaroto et al. 2018) examined the antimicrobial effect of titanium discs coated with different types of TiO2 (anatase and rutile) and concluded that when these were subjected to UV-A for one hour, A-TiO2 (anatase) and M-TiO2 (mixture of anatase and rutile) exhibited an antibacterial action by 99.9% and 99% respectively, whereas R-TiO2 (rutile) did not exhibit significant bacterial reduction.
A cubical function curve fit was added to the data, shown as dotted blue and black lines in Figure 5(a), to assist in understanding the general trend of the photoelectric reaction to be essentially different, and it appears to be in favor of the UV illuminated discs (the more negative the current the higher the photogeneration).

This stage is based on reliability growth of equipment that is indicated the deterioration process of failure components, it can be build from maintenance data history or condition data monitoring..
Research publications have shown that the timing of expected lifetime of an equipment obtained by several stages (Figure 3): · Reliability growth can be done by monitoring the maintenance history data or the condition monitoring data
Maintenance history data Maintenance history data is document recorded of every failure that have done on machine.
Condition monitoring data Data Condition monitoring is a document about the current machine degradation and its evolution.
Reliability growth can build from the kind input variable such as maintenance history data or condition monitoring data.

All background removal and data analysis was performed using the JADE 9 software from Materials Data, Inc.
The data were obtained using three different instrument configurations for each sample, yielding SANS data for a scattering vector (Q) range of approximately 10-3Ǻ-1 to 1Ǻ-1.
Subsequent analysis of the SANS data was performed using the Irena package [10], which also operates within the Igor Pro software.
The measured electrical resistivity data and the corresponding JMA fits are given in Fig. 1.
SEM images of the evolving precipitate microstructure in Waspaloy upon aging at 800°C under increasing aging time The microstructural data needed for Eq. 4 was obtained from the volume distributions fitted to the SANS data.

Also technology of trajectory reconstruction is presented by using limited measurement data of target.
But it could only acquire vehicle’s trajectory data.
Reentry vehicle trajectory data have three sources, separately are seismic system measurement data on board, GPS measurement data and earth station measurement data.
In nature technology of trajectory reconstruction is one of processing method of measurement data.
We could record telemeter data and retransmits without adapting any ways to alleviate interrupt.
