Ni-powder is obtained by the reduction of nickel nitrate in hydrogen.
After reduction, 2% paraffin dissolved in alcohol is introduced, followed by a homogenization for 90 minutes.
Before utilisation Cu-powder was deoxygenated through reduction into hydrogen.

Results indicated that salinity caused significant reduction in germination vigor (GV), relative percentage of germination (RGP), relative radicle length (RRL).
Furthermore, salt induced adverse effects at the germination and early seedling growth stages cause a substantial reduction in growth and yield.
GV reduction ranking for four species was oil sunflower > rape > soybean > false flax when saline concentration increased from 0 to 3g/L.
But, more insects caused damage to false flax when it was grown in saline soil in north of China compared with soybean, rape and oil sunflower (the data is not shown).
But, after droughty spring in north of China, it grew so quick so that its height of growth, development and yield were much better than other four species (data did not be shown here).

Thermally coupled cold forging analysis requires thermal conductivity, specific heat, heat transfer coefficient between the workpiece and the tool, and many other data, in addition to the temperature dependence of flow stress and friction coefficient.

Heat source calibration was carried out using two sets of data: (i) cross-weld macrographs, taken at specimen mid-length to ensure steady-state conditions had been reached; and (ii) thermocouple data, acquired during welding at several locations along the specimen.
Thermocouple data permits long-range calibration of the heat source (i.e. overall weld efficiency).
Short-range temperature distribution is calibrated using cross-weld macrographs (left), while long-range thermal history is calibrated using thermocouple data (right).
Complementary diffraction and stress relaxation measurement techniques were used to ensure confidence in the accuracy of the measured data.
In both cases, it is evident that the solutions from the mechanical model are in good agreement with measured data, thus validating both FE models.

For analyzing the transient behavior due to thermal effects, a series of projections were taken from two consecutive data scanning using the same number of projections.
Simulated CT data: (a) reconstructed sphere with total displacement of 10 mm and (b) with total displacement of 0,1 mm; (c), (d) representations of the circumferential line extracted from (b) Correction of thermal drift effects on CT measurements Projection based correction.
It can be observed a significant amplitude reduction of the 3 UPR harmonic for the corrected profile.
With the correction, a reduction of approximately 60% on the average RONt value can be observed.
Comparison between RONt values obtained from original and corrected profiles Conclusions This paper described the effect and an approach to minimize the influence of thermal drifts during the data acquisition with CT systems.

Software Reliability Demonstration Testing Plan Based On Bayesian Theory Qiuying LI1,a, HaonanTong1,b 1 School of Reliability and Systems Engineering, Beijing University of Aeronautics and Astronautics, China ali_qiuying@buaa.edu.cn, btonghaon@163.com Keywords: Bayesian; Demonstration testing; Software reliability; Plan; Zero-failure data Abstract.
To address this problem, by introducing the construction method of multilayer prior distribution function into the software reliability demonstration testing plan, this paper put forward a new Bayesian software reliability demonstration testing plan with zero-failure data, which can be used for highly reliable software reliability demonstration testing.
This paper put forward a new Bayesian SRDTP by constructing multilayer PDF with zero-failure data, whose main idea is to select the decreasing function of reliability parameter as the kernel function of PDF, which appropriately describes the characteristics of highly reliable software with the probability that failure probability takes a large value is low and failure probability takes a small value is high.
Compared to TBSRP , the test case number’s reduction is 2156 (72%). 2) TBSRP chooses Beta function to depict PDF, but when the corresponding PDF is , namely failure probability obeys uniform distribution, which obviously violates the characteristics of highly reliable software.

Air permeability tests showed a moderate reduction in air flow rate due to surface coating, while maintaining acceptable breathability for filter applications.
The crystalline structure were conducted using data analysis software provided by Rigaku Corporation.
The diffraction peaks observed at 2θ values of 25.31 °, 37.0 °, 48.03°, 70.28 °, 74.22 ° and 27.41°, 54.28° correspond to TiO2 P25 comprising the (101), (103), (200), (220), and (107) crystal planes of the anatase phase and (110) and (211) crystal planes of the rutile phase, in accordance with the standard data from the ICDD database (PDF Card No. 00-064-0863 and No. 00-064-0863, respectively).
When chitosan content was increased (TiO₂-P25 fixed at 10 wt%), a significant reduction in air permeability was observed.
Although a slight reduction in air permeability was observed due to surface coverage by the coating, the material maintained sufficient breathability for use in air filtration systems.

In detail network configuration, power consumption, data acquisition and data aggregation, signal analysis and data reduction as well as reliability and robustness are discussed.

Data Aggregation and Signal Analysis.
Such data aggregation and data reduction methods are also in general needed to minimize the data traffic that is of interest if the monitoring system consists of a high amount of motes.
The next steps are to look for efficient data reduction methods as well as for sufficient algorithms for signal analysis, so that the great amount of measured data is reduced to only a few relevant data.

Different strategies have been developed to fabricate oxygen deficient TiO2 photoanodes, such as hydrogen treatment, thermal annealing, electrochemical reduction, flame reduction, and chemical reduction.
Flame Reduction Method.
Other Chemical Reduction/Oxidation Methods.
The probe beam can also be in the form of a white light to allow multiple probe wavelengths at the same time, significantly reducing data acquisition time [160, 165, 166].
The two-dimensional false-colored TA data of the H-TiO2 and TiO2 with UV (380 nm) excitation indicate the spectral location of the maximum transient bleach (TB) features (Figure 15b and c).
