Data temperature from a confine room space, showed that the temperature would constantly drop from 31 ̊ to 28 ̊C from 12 am to 8 am.
The focus time for data logging is from 12 am till 7am where the expected temperature drops from 32°C to 27°C.
The average power consumption plotted hourly on 4 consecutive days dataas in Fig. 6(b) & 6(c) was at 4.1 kW and0.35 kWh from 9 pm – 9 am.The total estimation saving per month calculatedbased on current tariff is between ranges RM0.85 - RM1.34 cents for the prices below 200 units consumption and above 200 units consumption calculated as shown in Table 2.The controller could result in approximately 27% bill reduction vs the manual mode which given a constant power consumption over the hours.

Since metal acetabular cups rarely fail, clarification and control of the loosening behavior of acetabular cups may directly contribute to the reduction of revision rates[1-3].
Statistical analysis utilizing revision repository data in Europe and the U.S. showed that although hydroxyapatite coatings reduce the revision rate in the short term [4], their effectiveness is not statistically significant in the long term (>15 years) [5], and may even increase the revision rate.
Summary Displacement data successfully confirmed the viability of cantilever-based measurement by observing rotational movement on the X axis and cup migration toward the top region of the acetabular cavity, corroborating the displacement phenomena described by Nguyen et.al..

Because of the long control channel, the magneto-rheological fluid can generate congestion, which leads to the reduction of control flexibility.

Data is also presented on the post-moulding
shrinkage.
Part shrinkage is a geometric modification (can be a reduction or an expansion) in the size of the part.
All signals were recorded with a Kistler data acquisition system.

Single slope ADC with half-period counter
Conventional counter taking use of the rising or falling edge of the clock only generates one data within a clock circle.
It means that two data will be generated in one period.

As countermeasures against the springback, Yoshida [2] suggested the introduction of partial bead on die and width reduction of part geometry.
Both methods required experimental data for validation.
In the statistical approach [1,4] methods such as Design of Experiment (DOE) and multi-regression are to used derive a predictive model based on historical data.

Introduction
With the increasing environmental consciousness, further vibration reduction is needed to meet the requirements of living environment and the relevant national laws and regulations [1].
These data are stored in a database, which are interpolated in calculations.
The vibration acceleration signal of transformer core is collected by a triaxial vibration transducer, Kistler Group, and data are processed and analyzed by SQLab II vibration and noise test system, HEAD Germany GmbH, were used to measure no-load transformer core vibration.

When the vibration compensation is switched on, a reduction in the disturbance movement of the fringe pattern is clearly observed.
The data were retrieved as the original measurement and illustrates that the compensation vibration can be used to overcome environmental disturbance.
The measurement speed is only restricted by the frame rate of the CCD camera and the data processing speed.

After neatening these data, single factor evaluation matrix can be determined.
In the secondary risk, the design quality risk, basic data risk, site condition risk, design changes risk, financing risk and operating equipment risk also have a great influence on the subway engineering.
The decision-maker can make the right judgments in risk control, risk reduction and risk transfer through determining the level of these risks
