Co-firing Refuse Derived Fuel (RDF) from Municipal Solid Waste (MSW) with coal presents a promising approach to urban waste management and reduction of fossil fuel dependency.
The exhaust gas treatment system incorporated a series of components: a gas filtration unit (10) for particulate removal, a cooling box (11) for temperature reduction of the exhaust gases, and a gas analyser (12) for continuous monitoring of emission products.
Temperature measurements throughout the combustion process were recorded using K-type thermocouples (13) connected to a data acquisition system, enabling real-time monitoring and analysis of the combustion characteristics.
Temperature profiles and combustion duration were recorded at 1-second intervals using a data acquisition system.
Similar findings were reported by [27] in their comprehensive study of emission control in RDF-coal co-firing systems, where they observed a 35% reduction in CO emissions when excess air was optimally regulated.

The routers can not only collect, process, and analyze data such as temperature, humidity, light, infrared, ultrasonic, audio, image data and so on, but also fuse and transfer data.
For the sensors using TWI interface, they are in sleep mode when the data acquisition is not need, and turn to normal working mode only when the data request arrives.
Each device transport image data to the parent node, namely the next hop router.
The adjacent frame differencing algorithm can reduce data redundancy and make the image transmission more efficient, controlling the amount of image data efficiently.
Firstly, the energy-saving of data acquisition module is evaluated separately.

Marx Avenue, 20, Novosibirsk, Russia, 630073 zed_92@bk.ru, it@pfk-obnovlenie.ru, temlikova@edu.nstu.ru Keywords: asynchronous motor, numerical simulation, electromagnetic field, electrodynamic processes, squirrel-cage rotor, electrical motor design, experimental data, equivalent circuit Abstract.
The comparison with the experimental data obtained for the asynchronous motor with two squirrel-cage windings of the rotor is given.
Experimental data match the manufacturer’s test reports SPA “ELSIB” Inc.
Analysis of the investigation results of the ADKV asynchronous motors with squirrel-cage rotor shows the good agreement between the calculated and experimental data.
This fact, in turn, leads to the reduction in the number of prototypes in the process of preparing electrical machines for the mass production. 2.

A reduction of 150 mW/kg for a reduction of the A-parameter with 1° is possible.
The texture data were obtained by OIM measurements since the texture throughout the thickness of the samples is quite heterogeneous.
Shear bands have been observed after hot rolling from values as low as 15% of reduction and ending at relatively high temperatures of 800°C [2].
(b) ε-fiber intensity for: A) three different substrates after ICR (70% reduction) and DA at 1100°C for 30 min, B) FeSi with 2.4 m.-% Si, ICR reduction 40% and different DA treatments [7] Concentration profiles were measured by SEM-EDS, the resulting texture by means of EBSDSEM.
Fig. 4b compares the intensities of the ε fiber for different reduction and annealing.

This model was used to analyze the dynamic response considering dry friction damper by Griffin[3], Oden [4][5] which fits the experiment data.
Same operation is required for all corresponding nodes on contact surface Firstly, normal forces of nodes on contact surface is computed by static analysis and an array is defined to store the data; shear and normal contact stiffness formulas are deduced based on Greenwood-Williamson Model and Hertz contact whose equations show closely relationship with normal force [13].
Simulation Results and Comparison with Experimental Data The test system [14] for measuring the dynamic response of blade with assembled dovetail attachment is shown in Fig.6.
In addition, maximum reduction ratio (51.16%) is obtained when f=77Hz according to peak value of green curve (0.518mm).
In Fig. 9, numerical frequency (red with rectangle) fits experimental data (blue with circle) well, while maximum error is 1.43% at centrifugal force equaling 0.95KN.

Some data shows that 80% of purchase cost of an enterprise is concentrated at 20% of purchased products and varieties.
Meanwhile, the data sharing between buyers and sellers can be realized by relying on network platform.
A part of carbons is utilized in the production of methyl alcohol, in which carbon emission reduction relative to power generation by direct coal burning is realized, but still not enough.
To further make use of carbons and realize more emission reduction, carbon use can be more highly realized by using carbon capture technology or developing the organic products such as containing coal-made ethylene glycol and olefin longer carbon chain.
Realization of data consistency can promote all branches of a group to efficiently share data, improve customer service, and speed up capital turnover, save communication cost, and increase work efficiency and economic benefits.

The recovery data is summarized in Figures 1a and 1b.
The activation energy, Ua, and activation volume, Va, for the recovery process were adjusted to fit the experimental data.
The experimental data was fitted to the Verdier et al model [11] using Ua = 175kJ/mole and Va = 24.5b3.
Data was fitted using Ua = 155kJ/mole and Va = 20b 3.
The second pre-recovery treatment was of 65hr duration and resulted in a 50% reduction of the stored energy.

Then the sample was suffered from a strain rate of 0.01/min until the fibers broken completely, so as to collect the load-displacement data of the fiber bundle when the stress exceeded 10N.
Tab.1 Average value of carbon fiber bundle tension test sample length 5cm 10cm 15cm 20cm Fb(N) 0.08481 0.08070 0.07939 0.07830 L(mm) 50.4 100.3 149.2 199.9 The dimensions of the statistic data were removed and the reference scale was assumed to be 1cm.
Take the logarithm of the data so as to obtain the fitting line equation by least square method.
Length will lead to the reduction of strength, so fiber rope is unfit for bearing members which is too long.
The strength discreteness of fiber bundle in experiment is much greater than the calculated value, so strength reduction should be made in designing.

Among the different methods for reduction of moisture in solids we can cite the drying.
The values of the parameters hm, kl and kv were obtained by agreement between numerical and experimental data of average moisture content, using the least square error technique, as follows: , (11a-b) where ERMQ is the least square error, is the variance, n is the number of experimental points and is the number of estimated parameters [13].
The numerical values of the mean moisture content of lentil obtained in this study were validated by comparing with the experimental data reported by Tang and Sokhansanj [17], as shown in Fig. 2.
We can see that there is a good agreement between experimental and numerical data.
Excessive localized drying and heating for a certain amount of time reduction grain quality.
