Compared with traditional HOG and the improved PHOG, the proposed SMS_HOG algorithm acquires 5% recognition rate improvement and 50% processing time reduction.
Method “L-O-Sap-O” is able to select every image’s data as sample to make sure every image’s features are considered, contributing to a better reality.
Maybe the cause is that background edge information will take more effect and leads to the reduction of recognition rate.
The origin of the classification time reduction is from the smaller feature dimension.
Compared with traditional HOG and the improved PHOG, the SMS_HOG acquires 5% recognition rate improvement and 50% processing time reduction.

The result is the inclusion of the remaining best practices into one of four categories: (1) Ideal – high reduction of emissions can be achieved at low costs or even cost savings; (2) Economic – only limited reduction of emissions can be achieved at low costs or even cost savings; (3) Ecological – incurring high costs will achieve a high reduction of emissions; (4) Ineffective – incurring high costs brings only a limited reduction of emissions.
The information and the data necessary for determining the indicators are collected during this stage.
Given the extent of the assessment and the sensitivity of the used data, this section will present only a simplified version of the performed evaluation.
There are the following main outcomes of the preliminary analysis: (1) Purpose of evaluation – the objective of the case study is to evaluate the current GT level and to determine the potential for its improvement; (2) Scope of evaluation – inbound transport was selected as the system with the highest occurrence of emissions; (3) Availability of information – the data were collected by means of questionnaires and interviews with the employees of the company involved in this issue.
The main objective is Emission Reduction.

The alloy was rolled at room and cryogenic temperatures, and uniaxially compressed at room temperature and temperatures of 600-1100°C with different height reductions.
Extensive refinement of the microstructure occurs as the result of rolling with reduction of 80%.
The compression was performed to height reduction of 75% corresponding to true strain of ≈1.4.
At least 10 measurements per each data point were performed.
Rolling to 80% reduction at room temperature after forging increases yield strength to 1320 MPa but decreases ductility to 13%.

An overall reduction of defects was observed with decreasing growth pressure while the surface roughness increased.
Another issue is 4H-SiC epilayers grown on 4°off-axis substrates at high rates usually suffer from step-bunching and triangular extended defects [12,13] even though 4° off-angle substrates have attracted much attention because of the reduction in basal plane dislocations (BPDs) density and waste of ingots, especially for the large diameter ones.
An overall reduction of defects was observed with decreasing growth pressure.

As a consequence, it enables to individuate the combination of parameters that optimize the output avoiding misinterpretation that can be due to the singularity of the experimental data.
A full two level three-factorial design (23) was completed, three-way interaction was not considered for the lack of data.
The available experimental data, which was representative, did not fulfil the input to the 23 design.

The information monitoring center receives real-time data from all list subsystems through the GSM/GPRS network, function in the original data storage, statistics and analysis.
The gateway collects real-time data from each sensor node through the ZigBee network, gathers the original data for data encapsulation and protocol conversion, and then uploads data to the information monitoring center through the GSM/GPRS network.
CC2430 controls the MC35i terminal and transports data via RS-232 interface.
Next, the gateway packages the original data according to TCP data format and then establishing a TCP connection to send the data packets to the monitoring center database.
The application management software receives the original data from each subsystem, realizes the function of user management, data management, system parameters configuration, search, printing and etc.

Obviously, the reduction of test data would cause the reduction of data accuracy rating, and some quality problems and potential safety hazard would be disregarded at the same time.
In addition, this paper adopts test data based on tire laterodeviation characteristic, and chooses UA tire model which considers tire laterodeviation characteristic of sideslip[3].
In addition, we can also throw countertorque in main speed reduction gear to reduce the speed.
In the experiment, V1 are got 1, 1.05, 1.1, and 1.15 to proceed gradually, and we overlay every obtained test results data curve.
From Fig. 8 to Fig. 11 are repeated test data overlay speed, course angle, deceleration and lateral displacement curve graph.

Comparison of the top structure of the noise reduction effect of sound barrier, while taking into account the sound-absorbing material is added in the structure based on the common.
In the test of the same kind of structure by using different sound barrier sound absorbing materials were tested to obtain data, sound absorption properties of different absorption materials; insertion loss by replacing the top structure to test different, get the curves of different structure influence on insertion loss.
And the measured data and the front of the theoretical calculation results are compared, validate the theoretical results.

However, its potential needs to be validated using experimental data, especially when new combustion regimes are investigated, as in the case of flameless combustion.
In addition, Mancini et al. have performed the steady state numerical simulations operated in flameless combustion mode and compared with experimental data.
Conclusion Flameless combustion offers a practical solution for the reduction of pollutant emission such as NOX.
In this work, a short review of the numerical work in flameless combustion was summarized and the reduction of NOX emissions were discussed.
Studies showed that most of the numerical results are in agreement with experimental results in term of reduction of NOX emission.

Of them, 500°C isotherm method has been applied, relatively easy applicable and the simple method being able to use data by a test.
The estimate on the strength reduction ratio and loading ratio of the doubly reinforced concrete beam exposed to a high temperature has been limited only to the general strength concrete.
For a result of the fire resistance test for 180 minutes, the effective cross section area and effective cross sectional area ratio have been also listed up as per 500°C Isotherm method based on measured temperature data as shown in Table 3.
For the fire resistance performance, maximum 38% strength reduction factor has been also confirmed as per the effective sectional area
In other words, the strength reduction factor of reinforcement has an impact on flexural capacity of beams and also the section is correlated to an variation of the reinforcement temperature.
