Based on the cost and efficiency consideration, the bioaerosol reduction using a diluted water-soluble chitosan solution for a long-term treatment was practical.
Some studies have reported the use of chitosan as coagulant or fl˚Cculant for the removal of suspended colloids and as bactericides for bacteria reduction [5].
The removal efficiency ranged from 99.97-100% (data not shown).
The size of the inhibition zone caused by water-soluble chitosan was equal to that caused by 10 ppm of Streptomycin (data not shown).
Based on the cost consideration, the bioaerosol reduction using a diluted water-soluble chitosan for a long-term period was practical.

Meanwhile, we take imbalanced data into consideration in the paper.
Nathalie [7] systematically investigated the challenges posed by imbalanced data in the classification problem and pointed out that data skew would affect various classifiers.

Economic costs and loss reduction and energy saving should be taken into account when choose a transformer.
Accurate energy savings can be obtained by this algorithm without data collection during baseline period, all the need are parameters of transformer and energy loss during reporting period, thus the measurement and verification procedure has been simplified.
(3-1) After renovation or replacement, energy loss of original transformer under new load situation can be calculated with original transformer parameters and new load data, as shown as formula (3-2)
(3-2) As for energy loss of new transformer during reporting period, it can be obtained via data from meters or other measurements, or can be calculated by formula (3-3)
Loss reduction and power efficiency improvement of distribution transformer [J].

It means that welding process may lead to a great reduction in fracture toughness and the fatigue property for titanium alloy.
The fatigue crack growth data is important for an assessment of reliability and safety of structures containing crack-like defects.
This means that the welding process may lead to a great reduction in the fatigue property of the Ti-alloy.
It means that welding process may lead to a great reduction in fracture toughness and the fatigue property for titanium alloy.

In order to get more reduction of viscous drag, edge effect's influence is researched in this paper.
Fig. 3 Turbulent kinetic energy in central-axis cross-section structure of the rotor The stimulation data are processed using the methods of numerical analysis.
At steady state, fillet structure has a lower average drive current, a 19.6% reduction relative to the sharp edge structure.
The 0.5 mm curvature sample has already reached 19.6% reduction of drive current.
Drag reduction of Newtonian fluid in a circular pipe with highly water-repellent wall.

The current mainstream digital information integration methods can be generally divided into three types: (1) materialization method, also called as data warehouse method, is used for storing the integrated data sourcing from all data sources; (2) virtual method, also called as middleware method, applies a structure completely different from data warehouse; (3) materialization+ virtual method, also called as mixed method, makes compromise optimization on materialization method and virtual method, and then buffers important, less-changed, or commonly-used information locally with information buffer pool technology, but still acquires other information directly from information sources.
Conclusion First, compared with the traditional way of acquiring natural disaster monitoring and forecast information, the comprehensive information platform for the prevention of natural disasters based on ocean ships has attained a qualitative leap in the improvement of disaster prevention and reduction aid decision making.
Certainly, it is expected that the newest-generation ocean ship disaster prevention and reduction aid decision information system can be sooner born.

The experimentally collected data of this study provides the basis for further studies including tribometer tests and advanced friction modelling.
Figure 8 Optical data for the lubrication system pickled - dry at a stroke rate of 9 min**(-1) Figure 8 shows the optical measurement data of the lubrication system pickled – dry at a stroke rate of 9 min**(-1) that shows no sign of slippage based on the geometric data, given in Figure 4.
Data of the workpiece rotation confirms this (Figure 8, right).
Data of a specimen with sufficiently formed grooves shown on the left side and one with insufficiently formed grooves shown on the right side.
Lubrication system: zinc phosphate - dry Looking at the data for the lubrication system pickled-polymer these observations can be confirmed (Figure 11).

The percentage of biofilm reduction was 30%.
The percentages of biofilm reductions at 24 h and 48 h were presented in Figure 1.
A 30% reduction was noticed in 0.5% vanillin incorporated group at 48-h incubation.
Regarding the safety of vanillin, data from the Toxicology and Environmental Health Information Program (TEHIP) indicated that in closed-patch on human skin, vanillin (20% concentration) caused no primary irritation.

The experimental data showed variations in specific surface area, microstructure, pore size distribution, and amounts of iodine adsorbed by the activated carbon fibers.
KOH changed to K2O at activation temperature, and subsequently K2O changed to metallic K+ ions by reduction process.
As mentioned above, the reduction of silver ions on the surface of ACFs involves two stages: the first stage is the adsorption of silver ions on ACF surface, and the second stage is the reduction of Ag+ on ACFs.
Therefore, the creation of crystal nucleus has closely (a) (b) (c) (b) (a) relation to the oxygen-containing group on ACF, and the growth speed of crystal grain is determined by the reduction potential of ACFs.

It also reduces inventory costs by allowing lower WIP (Work-In-Process) quantity at any given time with the streamlined process.Generally a popular and simple way of cycle time reduction is to reduce WIP.
Coefficient of Variation (CoV) In most situations where data is presented, the reported indicators represent an average of the data points.
However, averages give no information about the distribution of the data.
CoV is a good measure of variation: (3) CoV can be used for any data set, as long as there are enough data points, typically more than 30 to have statistical validity.
With easy access to arrival and departure rate data, the factories now have one more data tool, besides CT, to pinpoint flow issues through the process.
