The aim of Rasch analysis is to find the extent to which observed rating scale data satisfy the measurement [14].
A preliminary study was done to gather all the data on the current practice at Company X.
Data for analysis is captured from both the IATF 16949 and TPS internal audit checklist.
Data for both internal audit checklists were collected from the internal audit checklist at the same production plant.
The comparison is important for reasonable and practical data.

Although with the accumulation of technical data concerning the developed materials and structural elements obtained from the research programs, they are not systematically used in large scale in civil construction.
Baseline data, implementation records and progress reports are necessary to monitor and evaluate the achievement of the project’s objective.
% of effective cost reduction in implemented housing using NOCMAT.
It should reveal the effective changes observed by government action and relative advantages of the innovation to the users, improvements in warranty, reduction in complaints, new norms created or adopted for constructions, reduction of construction deficit.

Welding was done to the heat treated steel plates (6mm) using SMAW process and applying AWS-E11016 electrode and as a result an over-tempered region in the heat affected zone was formed with a significant reduction of the ultimate tensile strength of the welded joint.
Reduction of heat input resulted in an increase in the joint strength.
Fig. 3 Intercritical annealing process 2 Hardness test Hardness test was conducted using a Vickers hardness testing machine (United) with a 0.5 kg load and holding time of 17 sec for each measured point and the data were displayed on digital screen.
The increase in the heat input resulted in the reduction of the joint tensile strength as a result of more softening of the HAZ. 2.
Electron beam welding of dual phase steel in the heat treatment condition resulted in a formation of very narrow HAZ with a slight reduction of its hardness values.

Introduction Rough set theory is a mathematical theory of reasoning about data which can be also used to deal with vague and uncertain problems [1].
Computing core and attribute reduction are very important issues of rough set theory.
For many algorithms on attribute reduction, the core is usually calculated at first, and then heuristic knowledge is combined with core to find the reduction.
Decision table reduction based on information entropy [J].
A quick attribution reduction algorithm with complexity of max {O (|U| |C|), O (|C| 2 |U /C|} [J].

In this study, reduction-oxidation cycles under different temperatures were analyzed.
The kinetic of the reduction reaction for oxygen carriers has been carried out by using TGA.
Seen from the DTG curves, there were two obvious weight loss peaks at about 450 °C and 790 °C respectively during reduction stage.
TG curves Figure 2 (a) Non-isothermal reduction curves between Fe2O3/γ-Al2O3 oxygen carriers; (b) CO at different temperatures.
The non-isothermal kinetic data were analyzed by using Coats-Redfern equation.

Multi-staged combustion was demonstrated as a practical NOx reduction method in the late 1970s [1].
Nitrogen element in liquid fuel is converted to nitrogen gas molecule through gasification reaction in reduction condition.
As shown in the data, the peak temperature region is situated around center of the flame, which is around 1200℃.
As shown in graph, this new type of burner has two major advantages in NOx reduction over other conventional burners.
The new type multi-staged liquid burner with partial oxidation shows very good performance on pollutant formation and reduction.

The size and shape of damage zone greatly affects the reduction of the compressive strength.
This KC-100 aircraft adopted the whole composite structure concept for environmental friendly through low fuel consumption due to structure weight reduction as well as for a competitive aircraft market.
Fig. 2 Impact test machine and residual compression test after impact damage To obtain reliable test data, many specimens for each fabric and UD laminate are used.
Conclusions This work is to investigate impact damage behavior and the residual compressive strength after impact damage of carbon/epoxy fabric and UD laminates which will be used for certification data base for the development of KC-100 small scale aircraft.

Electronic Tongue Data Acquisition.
Fig. 3 Cyclic voltammetric curve (1-6 are Mixed oil that the proportion is 0%, 20%, 40%, 60%, 80%, 100%) Feature Extraction Due to the data of cyclic voltammetric curve is very huge, in order to reduce data redundancy and reduce data processing burden need to original data feature extraction [10], in view of the laboratory get volt-ampere curve characteristics, system extraction characteristic value try to select each voltammetric curve of the peak current, minimum current and second minimum current, these point can reaction every material itself characteristic and greatly reduce the amount of data to be processed.
Soybean Oil Data Processing and Results Kernel Principal Component Analysis.
Principal component analysis (PCA) [12] is based on multidimensional data dimension reduction processing, use research m space Y instead of p space X (m < p), and low dimensional Y space instead of high dimension space of X the loss of information is very small principal component analysis through this combination can be to transform the original data for a group of new data new data the biggest characteristics is a former several component contains the whole sample space most of the information, therefore, can use a few principal component contribution score to describe the whole sample space.
A dependent variable data, the independent variable data partial least square respectively in X and Y extraction and composition and must satisfy as many carry each data table variation information, and the related degree to maximize implementation of X and Y to return without the satisfaction of regression, then proceed to the next round of component extraction, until to achieve more satisfactory accuracy stop.

The color of gold complex disappeared after the reduction step, indicating the gold ions were reduced.
The TEM image of gold nanomaterials after the UV reduction shows that the gold nanomaterials have multilayer structure as shown in Fig. 2(a).
From the SAXS data of the gold complex, D3OTP and LiAuCl4, this hypothesis was confirmed.
From the 1H-NMR of the dispersed solution, the alpha protons (-CH2SCH2-) disappeared (data is not shown).
Coordination of gold cations with hydrophilic part in D3OTP induced the layer structure of D3OTP, then control the crytal growth direction during the reduction process.
