The main problem is the multiplicity of parameter estimation solutions arising from using spatially sparse and noised-polluted data.
Almost all feature extraction procedures perform some form of data reduction.
The measured data is compressed into small dimension feature vectors.

Heavy vehicle cooling fan is seen as one of the main means of vehicular fuel efficiency reduction.
Therefore, in this research, the performance data of motor is to make use of measured data of Dynamo.
Motor efficiency in equation 1 is obtained from the measurement of motor performance data.
When we apply algorithm for taking account of CFD analysis and test data of motor, starting from random rotating speed, torque of motor testing data and torque of CFD analysis will converge to the same value following enough time of calculation.
Figure 8 demonstrate graphs for linking CFD of axial flow fan with testing data of motors.

This paper is based on the data taken from a typical engineering educational institution in India with a population of about 3500 peoples [4].
The data are collected for a period of year (May, 2012- April, 2013) and the following calculations are obtained
Table 1: Conversion factors Materials Kg of CO2 emitted /unit consumption Grid Electricity 0.446/ kWhr Diesel 2.34/ltr LPG 1.493/ltr Petrol 2.214/ltr Results and Discussion The assessment was made by accounting the data from the electricity department, administration department and some measured data and then the calculations were made by using conversion parameters.
This indicates the reduction of CO2level by 1.27%.
We express our sincere thanks to transport department, maintenance team, electricity department of SSN College and hostel for providing necessary data.

The present data have revealed the presence in the deformed substructure of a crystallite volume that has rotated towards the {311}<136> component in the interior of <110>//RD fibre grains as a result of a grain fragmentation process.
In total there were 12 rolling passes with an average reduction per pass of 7%.
They depicted the existence of different substructures within the a-fibre type based on different reductions in IF steel.
More extensive data gathering is required in combination with a more fundamental theoretical analysis on the basis of crystal plasticity model.
The present data do not seem to indicate that this is a major source of strain localization here, although not many GBs between misoriented rotated cube grains could be observed.

Keywords: Methane reduction.
Facultative methanotrophs reported recently could only utilize a few of C2, C3 and C4 compounds, which limited the application of methane oxidation in the engineering of greenhouse gas reduction due to the difficulty of cells propagation.
These data would suggest that methane is the more preferred substrate for M. sp.
Metabolic and biochemical characteristics of the strain open up a new possibilities for environmental biotechnology, such as some potential applications in methane reduction emitted from soil or landfills.

Summary of Background Data Kyphoplasty (KP) involves placement of inflatable bone tamp via unilateral and bilateral approaches.
Results Both unilateral and bilateral kyphoplasty resulted in significant pain reduction.
After reduction of the fracture bone, cement is deposited into the cavity created by the IBT to repair the fracture.
The two groups of KP resulted in marked and sustained pain reduction.
Chung et al[8] compared the outcomes of unilateral and bilateral KP and found out that bilateral group had a greater advantage in the reduction of kyphosis and the loss of reduction was less than the unilateral group.

On - line monitoring and state reduction
The focus of the overall concept is the on-line state space reduction allowing dynamical system monitoring.
Fig. 3 The state space reduction on the example of a tank In the second step of the concept, on-line state space reduction was carried out.
In the third and last step, the reduction was evaluated. 3.
It represents the loading and processing analyser data.
Within the on-line state space reduction, qualitative model components are reduced based on dynamic models and on data obtained from sensors and actuators.

On the basis of similarity conditions, laboratory model parameters were determined so that data acquired for the model may be referred to real-world structure.
Steel slender structures usually have small internal damping ratios and that is why they are frequently equipped with vibration reduction systems.
It is very important if model to be built will serve as a basis for synthesis of active or semiactive vibration reduction control system.
Considering the fact that the model will be used for study of vibration reduction system placed at tower’s tip, the proposed solution will be satisfactory.
