Opinions exist that Lean Six Sigma should be implemented in the large number of areas of the life, and its effects (essential improvement in financial results through the reduction of poor quality costs) are hard to overrate.
The cost reduction of poor quality in the 7th, 14th and 24th month (Fig. 1) is not relatively higher than the waste discovered almost in the whole range of the testing period.
Data collection based on assumed control limits used for quality assessment come from control charts designed for monitoring of process quality according to Statistic Process Control [6].
CTQ data, the technical and financial condition of a product development are used as the input to application of Theory of Inventive Problem Solving (TRIZ) [9].

Numerical simulations of the damper rig with a simple macroslip damper model were performed during the preliminary design, and a comparison to the measured data highlighted the ability of the basic implicit model to capture the resonance frequencies of the system accurately.
The modelling approaches developed must be validated against experimental data to ensure the correct prediction of the nonlinear behaviour.

Subsystem of data input and process: The quantity and quality of data are important to the accuracy of assessment and decision-making.
Some approaches of data pre-processing are as follows:The graphics digitizer or scanner is used to deal with the maps or remote sensing images, and transform the data form to a vector form, then store them in database.All kinds of attribute data can be input and stored in the attribute database by keyboard.The data of statistics reports, testing and analysis and investigations can be input into the attribute database using the same methods as the attribute data input.

According to the production data of a rolling H-beam factory, the FE model of hot continuous rolling process of H-beam is built.
In which ——Datum deformation resistance, that is resistance in condition of =1000℃, and s-1 ——the degree of deformation (logarithmic strain); ——the deformation speed; , ——the regression coefficient, whose value depends on the steel grade For the 25 steel, =150.6MPa，，，，，，。
In order to produce the proper size of the product, in the universal rolling mill, flange reduction will increase, which is bigger than that of web.
But the vertical roll on both sides rolles flange, the reduction direction is contrary to the direction of web spread.

Seismic Assessment of a Historical Tower with Advanced Numerical Model Tuned on Ambient Vibration Data D'AMBRISI A1, a, MARIANI V 1,b and MEZZI M 2,c 1 Università di Firenze, Firenze, Italy 2 Università di Perugia, Perugia, Italy a adam@dicos.unifi.it, bvalmariani2@yahoo.it, cm.mezzi@unipg.it Abstract This paper deals with the dynamic characterization and the evaluation of the seismic response of the medieval civic tower of Soncino (Cremona, Italy).
Ambient Vibration Data Historical constructions can not be tested with destructive methods; for this kind of structures the dynamic identification by ambient vibration data is the most appropriate test.
In particular, the stress level has been defined at the most critical sections of the tower: at the base, at the height of 12 m where the constrain effects of the surrounding constructions are negligible, and at the height of 19.1 m in correspondence of the first reduction of thickness of the walls.
In the examined case the dynamic identification tuned on ambient vibration data gave important information about the material properties and the boundary constraints.

In addition to the numerical works presented here, an experimental investigation on variation of values of strength parameters with time for a full process of setting for nitrogen foamed cement will provide solid foundation to the input data of the numerical model used here.

Therefore, improving the vibration performance of the printing press and designing the structure of anti-vibration and noise reduction to improve the quality and speed of printing presses is an important issue in the press product development.
Testing and analyzing related physical quantity can not only provide objective assessments to products’ quality but also reliable data of producing and researching.
Through vibration sensor, signal acquisition, analytical equipment and PC it obtain a series of data at all stage of rotary-machine-operation such as values of system input and output, vibration elimination, vibration isolation and vibration controlling.
Therefore, improving the performance of anti-vibration of the printing press, design of anti-vibration and noise reduction to improve the quality and speed of printing are critical issues in press product development.
The principle is it obtains the mechanical parameters, transformed into electrical data in proportion to it then.

The WPO10+4H2 blend at 25 °CA bTDC demonstrates an 8.7% BTE increase, a 10.5% BSFC reduction at full load, and substantial decreases in HC and CO emissions compared to diesel.
Data is logged for 15 minutes using 'Engine soft' software, with results averaged for accuracy.
The introduction of hydrogen in WPO blends results in a noteworthy reduction in BSFC, particularly with WPO10+4H₂ at 25°CA bTDC, showing 10.5% and 8.1% lower BSFC, respectively, at full load.
While hydrogen itself may elevate UHC emissions, its overall reduction is notable due to its higher concentration and efficient fuel utilization [15].
