This temperature was chosen on the basis of thermogravimetric analysis, revealed both dehydration and reduction processes ranges [4].
According to the electron diffraction data iron particles in all the samples are coated with amorphous SiO2 layers with thickness of about 3 nm.
Thus the complete reduction at MM homogenization procedure has not been achieved.
Mossbauer spectra and corresponding phase contribution for nanocomposites, obtained in course of precursors reduction in hydrogen at 400oC.
It cannot be explained by iron concentration only in accordance with Mossbauer spectroscopy data.

The results are well consistent with that of the vibration tests which provide the basis for further study of vibration and noise reduction.
The vibration tests of the reducer have been done and the collected data were analyzed with the HEAD acoustics multichannel vibration test and analysis system.
The finite element model is correct and which can provide useful theoretical basis for further study of vibration reduction.
The results are well consistent with that of the tests which provide the basis for further study of vibration and noise reduction.

Moreover, SVM was modified by introducing wavelet function as kernel for mapping input data into feature space.
Input data were vibration signals acquired from bearings through standard data acquisition process.
In the training process, the data set was also trained using RBF kernel function as comparison.

Experimental details The material studied was made by direct reduction of extra pure quartz and carbon.
After tapping from the reduction furnace, the material was cooled down, etched and cleaned with DI water.
Compared to literature data, the EBIC contrast values of dislocations at 100K are quite high - we cannot exclude that in our measurements the dark spot visible in the map is due to more than one dislocation.
Summary In this work we reported a first study of solar grade silicon obtained directly by carbothermic reduction of very pure quartz and carbon.
The data and information obtained by these analysis are used for an optimisation of a solar cell process for this material which is currently in progress.

A simple chemical reduction method was brought to prepare PtSn particles on GO.
XRD peaks of PtSn/GO co-catalyst prepared by a chemical reduction method.
Reduction of Pt usage in CEs of better performed DSSCs was demonstrated.
EIS data of (a) Pt electrode and (b) PtSn/GO electrode.
Summary PtSn particles on GO prepared by a simple chemical reduction method are promising to replace Pt as counter electrode catalysts for the reduction of I-/I3-.

Average data of each national level department (mining, transportation, product manufacture and distribution etc.) were used in the analysis.
This method makes collecting data easier, has obvious advantage on analyzing macroscopic carbon footprint and was mainly used to calculate carbon footprint of city or national level. [10] 2.2 Calculating content of enterprise carbon footprint Enterprise carbon footprint means the emission volume of carbon dioxide directly or indirectly generated in the product life cycle which is from obtaining material, manufacturing, package, transportation, and abandonment to recover.
Documentary evidence means the information recorded by paper or electronic media, including construction organization design, construction diary, photos, site certificate and completion data.
The persuasion of witness evidence is much less than physical and documentary evidence. 3.3.2 Data treatment Treat data according to the following procedures: (1) state the project; (2) identify and choose the source of carbon emission GHG relevant to the project and determine the calculation boundary referring to the carbon footprint expression of enterprise; (3) take relative formula for reference, calculate the amount of carbon emission and get the total amount of carbon emission of the whole project; (4) estimate the carbon sink (carbon capture) capacity of landscape engineering in operation process; (5) obtain carbon footprint value of life cycle of landscape engineering after positive-negative comparison between carbon resource and carbon sink.
Carbon Footprint and Energy-saving Emission Reduction [J].

A reduction in the concentrations of exhaust gas emissions was notified.
Although some anomalies are observed to the data, but overall a reduction in CO emissions was found using W/D nanoemulsions compared to the neat diesel.
In spite of having some fluctuations in the data, the general observation was an overall reduction in CO2 emissions using W/D nanoemulsions compared to the neat diesel.
An overall reduction in NH3 emissions was observed using W/D nanoemulsions compared to the neat diesel.

Compared to the old control software on these machines, nearly 70% of functions are reused in the new one, which leads to a reduction of the research and development time eventually.
Introduction Additive Manufacturing (AM) is a group of techniques used to quickly fabricate a scale model of a physical part or actual part using three-dimensional computer aided design (CAD) data.
This part adopts a tree control to display fabrication data.
The corresponding data is a tree structure with height 3.
Application cases show that, the reconfigurable control software works well on two different AM machines, and nearly 70% of functions are reused, which leads to a reduction of the research and development time eventually.

In these methods, the vibration data are first pre-processed to obtain a reduced feature vector that contains the key characteristics of the original data.
Both techniques show that the spectral data for the repaired bridges are significantly different from the data for the undamaged structures, which is expected given the nature of the repair.
incoherent frequency shift The same ANN as used on the experimental data was also used to classify the simulated data, although it was retrained using a subset of the simulated data for the undamaged and fully damaged cases.
As in the experimental data there was no confusion when the ANN was used to classify test data from these two extremes.
The problem of identifying data sets that differ significantly from an original undamaged data set, the novelty detection problem, requires a different approach to training the ANN (unsupervised learning) and these methods are currently being applied to the data sets to achieve this.

Each alloy was prepared with two different cold rolled reductions.
Two different cold reductions (CR) were performed.
LCR 1020 is SAE 1020 with 39 pct cold reduction.
Figures 2a-2b show the reduction in pearlite band width with greater cold reduction.
The data in Table 1 also show that a slight decrease in Ac3 was observed in both LCR and HCR 15B25.
