Reduction of rate of failure (ROROF) in order to enhance operational efficiency.
Let f be the distribution function corresponding to our experimental data (X) and G be the distribution function corresponding to data (Y) from industrial machine.
Furthermore table 1 shows the comparative performance data for pilot and industrial nut/fibre separators.
We shall use the Asymptotic Relative Efficiency (A.R.E) test, which is the most universally accepted method of comparison, to analyze our data.
And p - value is the minimum significance level at which the null hypothesis would be rejected for the given data.

There was 50% reduction in CO emissions due to use of improved cookstoves as compared to traditional stove.
The authors found that at high secondary air flow rate there was reduction in CO and PM emissions whereas there was increase on NO emissions.
Houshfar et al. [28] reported about 85% reduction in NOx emissions with staged air combustion while conducting experiments on a reactor using demolition wood pellets as a biomass fuel.
· Field studies on both the cookstoves will be conducted in more number of families and the real time data on fuel consumption and pollutant emissions will be analysed and changes in design of the cookstoves will be modified to make them user-friendly.

A slight reduction in strength was anticipated for some concretes between 105 °C and 320 °C, which was also accompanied by the appearance of micro cracks [8].
By exceeding 300 °C, PP fibred concrete can become more highly porous than plain concrete, thus causing durability issues and probable reduction in the mechanical proprieties [12-15].
At this range of temperature, literature indicated a reduction of tensile properties of SF and peeling off of cement matrix from its surface.
Another NDT process that doesn’t necessarily involve the compressive strength data in its evaluation is the resonance frequency method, which uses its measurements to directly predict the degree of thermal damage.
Although all specimens showed significant reductions of UPV values at 800 °C, the results confirmed the greater positive effect of SF than PP in retaining higher velocities of FRCs since UPV reduction in SFRC was around 10%, 15% and 5% lower than that of NC, PPFRC and HFRC respectively.

DIMS-CS system itself still needs to do data and business exchange with other systems.
Its architecture is shown in Fig. 2: Fig. 2 Architecture of the DIMS-CS While the explanation of each layers is as follows: (1) Data acquirement: includes the current basic data of the disastrous area (such as spatial geographic data, population, juridical person information, socioeconomic data, etc.); data collected in the live site and uploaded by mobile equipment or Internet; data acquired by data mining from the Internet, including web portals, social network, and the business data from other systems, such as delivery status of relief material, in-time location of medical rescue teams, etc.
(2) Database: manages various kind of data, including the existing basic data of the disastrous are, various disaster information (UGC-DI, PGC-DI, M-DI), users information (profession and public) and management data of system (such as log)
(3) Platform: deploys the primary platform management functions, including GIS platform (digital map update, disaster information labeling and spatial analysis), data merging (PGC-DI and UGC-DI), data exchange (with other systems), and data mining
All these data is merged on the platform and released to the public users, professionals and SNS websites through the data release module.

The real rotating speed fluctuation solution could be obtained after the data of signal acquisition post-processing by the methods of frequency spectrum analysis and modal analysis.
Based on data of signal acquisition, using the methods of fourier phase frequency spectrum, logarithm amplitude frequency spectrum, and self-power spectrum, the quantitative expression under the quantitative analysis stable state was obtained.
Using these testing data, the appraisal of the shafting fatigue life should be analyzed and the torque amplification factor could be calculated.
