The ultrasonic attenuation shows the rate of sound energy reduction when an ultrasonic wave is propagating in a medium which is the lithium niobate tellurite glasses.
As the sound beam propagated through the material, there will be a reduction in sound intensity known as attenuation.
Fig. 1: Schematic diagram of experimental method. 2.3 Data Analysis Fig. 2 shows the typical time domain signal of ultrasonic wave propagation in a sample.
All the data calculated and gain from experiment have proved that the attenuation coefficient increased due to absorption (UV-Vis absorption) and scattering (TEM images) phenomena in the glass system.

All these data were used to determine the anisotropic coefficients.
The results were compared with experimental data.
It was found that the Yld2000-2d model precisely predict well with experimental data than the other models.
Furthermore, anisotropy coefficients of the anisotropic yield functions, Hill’s 48 and Yld2000-2d, were calculated using the data from Table 1.
Obviously, In Fig.3b) the predicted yield points and yield locus for Yld2000-2d model precisely predict well with experimental yield stress data.

Estimated thrust values by the derived models showed a good fitting with actual thrust data for both models, which validated each model’s accuracy.
For both engines, the estimated values of the engine thrust by the derived GA model and the actual thrust data were compared.
A good fitting between the estimated values and actual data is achieved as depicted in this figure.
The actual data obtained from engine manufacturers were also utilized in the development of the neural network (NN) propulsive model.
Figure 2 Comparison of GA and NN model results with the actual cruise thrust data of TF-30 turbofan engine.

The results were compared with the simulation data of the 2D model.
Meanwhile, with the increase of gap width, fluid velocity decreased, the throttling effect between labyrinth gaps is reduction.

The data indicates the feasibility and practicability of this algorithm.
The gradient substituting formula (12) is : (13) Simulation and analysis Using the model of motor is BCL-36.71.24.93.B.C.01, its technical parameter is: extra power 150W,extra voltage 24V,extra rotate velocity 6650rpm,reduction ratio 32,the maximal driving torque 16.2N.m.

A new technology of titanium metal powder production by means of two stages reduction of titanium dioxide, using magnesium and calcium, has been developed and patented by VELTA, Ukraine.
In addition to the grades of pure metal titanium, the proposed technological scheme makes it possible to obtain various titanium alloys powders by joint reduction of titanium dioxide with oxides of alloying elements.
Taking the example of China, according to data from the largest titanium powder manufacturer in China Jiangsu Jinwu New Material Co, the growth of titanium powder for AM in 2023 was approximately twice that of the previous year, while the demand for MIM powder more than quadrupled that of 2022 [2].
VELTA Ti process allows manufacturing alloys directly during the reduction of titanium containing raw materials (solid solution of alloying element oxides in technical titanium dioxide).
Summary A new technology of titanium metal powder production by means of two stages reduction of titanium dioxide, using magnesium and calcium, has been developed and patented by VELTA, Ukraine.

Calculation results and analyses 3.1 Electric field distribution In a light coupling tapered fiber, owing to the reduction of the core and cladding diameters, the fundamental mode spreads out the cladding region being a dynamic evanescent fields surrounding the fiber waist.
SPR transmission spectra of the tapered optical fiber with different thicknesses of gold-film. 3.3 Investigation the diameter of the waist of tapered fiber-optic In a light coupling tapered fiber, the reduction of the diameters of the core and cladding leads the fundamental mode coupling to the cladding region and eventually beyond the external sample.
Furthermore, the reduction of the waist core of the tapered fiber-optic leads to the evanescent wave vector changing.
Using the MATLAB R2012a to fit and analysis the calculation datum of the resonance wavelengths and the refractive index we conclude that the SPR wavelength variation complies with linear variation with the refractive index changing, and the correlation coefficient=0.9992.

One of advantages of magnesium alloys consists in mass reduction of mobile technology, what contributes to a significant reduction of fuel consumption and thus also to reduction of combustion products [1].

The testing data will be marked by the feeding cutting depth L; upon each feeding of 10mm, the data of the sensors X and Y will be saved, which are named as the sensor X01, Y01~X09,Y09.
During each test, 18 data sets will be recorded.
Data comparison and test conclusion.
As is shown in Fig. 11-14, we can draw following conclusions: Fig. 11 Test data comparison of cutters 1, 2, 3 Fig. 12 Test data comparison of the cutter 2 Fig. 13 Test data comparison of cutters 3, 5 Fig. 14 Test data comparison of cutters 2, 4 (1) General rules of the cutting vibration of the tap cutter.
Due to the cutter wear, the vibration data value is slightly increased.

The Y-doped films exhibit an elevated electron Fermi level,which may enhance band bending to lower the density of empty trap states.Because of this Y-doping, the Dsscs can alleviate the decay of light to electric energy conversion efficiency due to light intensity reduction.
X-ray photoelectron spectroscopy data were obtained with an ESCALab220i-XL electron spectrometer from VG Scientific using 300 W Al Kα radiation.
