Since the reduction of petroleum production by Organization of Petroleum Exporting Countries (OPEC), the research on alternative fuel for diesel engine has gain interest.
The use of DHW Emul can give significant reduction of NOx and Smoke emissions without deterioration of CO emission.
Engine performance and emissions data are obtained under stable operating conditions at engine speed of 1500rpm.
Hydraulic oil content in DHW Emul give good effect of CO emission reduction, however, the chemical reason of this result is still under investigation.
DHW Emul show simultaneous reduction of NOx and Smoke compared with diesel fuel.

For these points, reusing knowledge from historical data becomes a natural option.
Based on company's sales records and product documentations, the links between customer needs and purchased products related to which product satisfies which customer can be identified and they are represented as {( * * ,s tr v )|∀s∈[1,S],t∈[1,T]}, which acts as the original data of knowledge discovery to product family planning in this research

In addition, a coordinate transformation is introduced to simplify the three-dimensional guidance law and reduce training data for the neural network.
The optimal trajectories obtained for various terminal flight-path angles are no longer needed for the training data when the difference between the OC and the TC is small.
The vertical flight-path angle of the velocity in the TC is ref fγ , those of optimal trajectories for training data.
The neural-network guidance law and the got estimator are designed using missile data [4].
Both the neural networks for guidance and the got estimator are trained using these data.

For CCUS technology to be widely used, more accurate evaluation work based on geological, geophysical, geochemical, rock mechanical, and other data should be done. 
Illustrated Case Study The CTS-PTA is tabulated using secondary data from a variety of sources.
Table 1 shows the CO2 data sources (S) and demands (D).
The algebraic targeting approach was used on secondary data to assess the potential CO2 utilisation management by meeting CO2 demands at different purities.
The use of this innovative approach resulted in a 47% reduction in CO2 storage.

The impedance data can be collected over a broad frequency range.
This part of the electrochemical impedance data interpretation was critical since several equivalent electrical circuits can be used [12-14].

In this research, PdCoNi nanocomposites supported on graphene were prepared by chemical reduction reaction with a strong reducing agent.
Experimental Synthesis of metal nanocomposites supported on graphene The metal nanocomposites were synthesized using simple reduction of metal catalysts and graphite oxide (GO) using NaBH4 as the reducing agent.
The reduction was performed by adding an excess of NaBH4 into the mixture and stirred to obtain a black slurry.
This peak can be used to calculate the electrochemically active surface area (EASA) of the catalysts by determining the columbic charge for the reduction of palladium oxide [6].

Electron back-scatter diffraction (EBSD) measurements were carried out on the QUANTA FEG SEM, with TSL data acquisition software.
A close observation of the α and β fibres indicate the weakening of Cu and Bs texture components with increase in the cold rolling reduction.
In order to understand the texture development in the three types of alloys, ф2 sections of the ODFs for similar cold reduction (70%) were compared.

Reduction of Power Grid Losses by Using Energy Efficient Distribution Transformers Themistoklis D.
As a result, the reduction of no-load loss of distribution transformers has attracted in recent years the interest of researchers, transformer manufacturers, and electrical utilities [6].
The reduction of no-load losses and the consequent minimization of operating and manufacturing costs of transformers can be achieved by methods of forecasting no-load losses during the design phase of the transformer.
The specific experimental setup involves the usage of search test coils, a sampling card and appropriate computational analysis of measured data using LabVIEW software [9]-[12].
The development of the proposed methods has led to the reduction of the manufacturing and operating costs of wound core distribution transformers.

Based on the presented data, a possible growth model is proposed to clarify AIC mechanism.
The reduction of agglomerations on the a-Si surface is due to the diffusion of Al agglomerates into silicon.
From the XRD data, XRD signals at Si(111), (200), (311), Al (111) and Al (200) were detected which indicates the formation of nanocrystalline material.
Inspection of the data of Fig. 2 reveals that the AIC process has produced crystalline fraction at temperature above 500oC, with a peak centered at around 514 cm-1.
There is a clear tendency of reduction of resistivity as the annealing temperature increases.
