Simulation results have shown that the proposed model has merit and agrees with published experimental data.
However, the results they got were deviated from the experimental data.
Therefore, modal reduction is practical when calculations effort and noise rejection is crucial, for example when the model is used for switch vibration control purposes.
Modal reduction is based on excluding modes with lowest Hankel norms [8].
The technique allows for modal-model reduction based on Hankel norms of individual modes.

(2) According to the model, if we only consider the circuit losses, Formula (3) stands for the energy consumption when receiving k bits of data, and Formula (4) represents the energy consumption when a node applies data fusion on k bits of data, wherein Esb means the energy consumption of data fusion per bit of data
Improvement Based on Data Redundancy.
(7) Set a similarity threshold ρt, if ρ ≥ ρt, we take the data collected in the nth round as redundant data which have no impact on the final data fusion.
So the data does not need to be sent to the cluster head, and the cluster head can use the data collected in the mth round when performing data fusion.

It may not only bring reductions in CO2 emission, but also may lead to savings in expenditure on energy.
The reduction of costs via energy saving could be the first purpose instead.
These data can teach all those involved how much energy is consumed uselessly and how they can reduce it.
Among the group members, from data analysis, essential problems for reducing energy consumption will be discussed, and their countermeasures are to be proposed and implemented selectively.
In this case power reduction rate was 30 percent and return on investment (ROI) was 2.7 years[6].

The test data was recorded using an HFFB with a 1:400 scale rigid lightweight foam model mounted on it.
Each test lasted 250 seconds (approximately 4 hours in full-scale) and data were sampled at a rate of 116 hertz.
Applying the site-specific meteorological wind climate model to the test data gives base moments that are used for calculating the GWF.
Three TLD systems with varying water mass are designed and evaluated using data from HFFB tests conducted at the BLWTL at Western University.

Comparison of the calculated and technological data shows that the melting ends in conditions close to chemical equilibrium.
The initial data concerning the chemical composition of the phases were treated using a mass balance equations and data concerning the mass fraction of each phase.

The methodology involves analyzing technical and operational data from Canada, Finland, Zambia, and South Africa, adapting it to Ukrainian conditions, and modeling the integral economic effect.
The dependence is described by a saturating Hill function, with parameters determined via the least squares’ method using empirical and calculated data.
For the first time, global operational data have been integrated with modeling for Ukrainian open pits, producing a tool adaptable to various mining and geological conditions.
Practical data indicate that the effect increases nonlinearly: the largest gains are achieved when electrifying the most energy-intensive segments, after which the rate of growth declines.
The first year of operation should be conducted as a "pilot phase" with detailed data collection on fuel savings, emission reductions, changes in trip times, and maintenance costs.

Active noise reduction method has low frequency noise control effect is good, can be selectively noise elimination and other advantages, has become the focus of attention.
This paper establishes the simulation model of the active noise reduction system in the MATLAB/Simulink environment, the simulation analysis of a large number of the relevant parameters of active adaptive control algorithm; in a light bus was constructed in the active noise control system in vehicle, the implementation of active noise reduction test, has achieved a good result.
When the engine speed and stable operation in 1080rpm and 2400rpm, the experiment data are analyzed, comparison of the test results of active control system of driver's right ear before and after the opening time curve and frequency curve are shown in Figure 3 and Figure 4
Sound pressure level of each noise peak value was synthesizing, get the overall sound pressure level of interior noise, it can calculate noise reduction amount of vehicle active noise reduction test.
According to this method, calculates noise reduction amount of adaptive active noise control test under two different speed of engine, as shown in. table 2.
