Because EDM is heat energy machining, the reduction of the magnetic flux density must be considered.
On the other hand, when the nonmagnetized material was machined using EDM, the inversion of the polarity did not occur at any machining depth, and the reduction of the magnetic flux density depended on the hole depth.
Therefore, the measured values were lower than the surface data shown in Fig. 1.
The data from the Tesla meter was logged at a sampling interval of 0.5 s during machining.
However, clearly identifying the source of the variation based on the limited data is not possible.

The lines drawn refer to the best fit of the experimental data to a numerical solution of the continuity equation with sf as unknown parameter.
The symbols refer to the data measured, the lines drawn to fits with the simple model explained in the main text.
As the treatments used act only on the surfaces (with a possible exception for the deposition of Si3N4) the change of the decay behaviour is due to changes of s: The largest reduction of s is observed in a I2/ethanol solution, a somewhat smaller reduction after Si3N4 deposition at both surfaces and the smallest reduction after a HF dip.
This yields: HF dip 2.5*103cms-1 < s < 3.5*103cms-1 Si3N4 covered 7*10 1cms-1 < s < 3.5*102 cms-1 In I2/ethanol solution 0 < s < 2.5*10 2cms-1 It is clear that a HF dip does not suffice to reduce s and increase τs enough to neglect (τs)-1 in Eq.3 so that the measured decay time τeff corresponds to τb: If this is assumed the data in Fig.3 give τb=6.5µs, although the measurement in I2/ethanol solution shows that τb is at least 50µs.

Because of the unreasonable exploitation method and technology, many oil resources are difficult to be exploited, and the waste of resources is also very serious.According to the data provided by Swiss bank's recent global oil status report, the proven oil reserves on earth are about 1.8×1012 barrels.Converted into the service time corresponding to the consumption level, the world oil can be exploited for about 46 years.Therefore, improving the way of oil exploitation is a subject that all countries need to face.In China's oil reserve structure, with the reduction of conventional oil resources, the proportion of low-efficiency reserves and low-grade reserves that are difficult to recover in the long-term development of old oilfields is increasing, and more scientific exploitation technology is paid more and more attention in the current oil situation.For heavy oil resources with large specific gravity and high viscosity, it is necessary to study its recovery technology.For China, heavy
This method has good viscosity reduction effect, but the treatment capacity is small.
Upgrading and viscosity reduction technology is relatively mature in heavy oil recovery technology.
(4) Combined with steam huff puff, Steam flood, SAGD and in-situ combustion technology, horizontal well and multiple medium well technology can make heavy oil reservoir obtain better development effect, which should be paid attention to in the future heavy oil thermal recovery technology. 4 Expectation (1) The development of heavy oil viscosity reduction technology is diversified: physical viscosity reduction includes thermal recovery method, thin oil blending method, ultrasonic method, etc., chemical viscosity reduction includes upgrading viscosity reduction and emulsification viscosity reduction, etc., microbial viscosity reduction can also play a certain role, and composite viscosity reduction is a comprehensive application of a variety of principles
(3) The evaluation method of heavy oil viscosity reduction is not perfect, and the dynamic viscosity reduction flooding evaluation based on static viscosity reduction evaluation is developing gradually.

The measurement from the test model verified the predicted data and a yearly potential from nocturnal cooling in this region was established.
The calculated value of Two inherit certain amount of uncertainty due to the uncertainty of input data into the mathematical model such as the actual wetted area of the roof, climatic data such as cloud cover, wind speed and ambient air temperature, relative humidity and dew point.
Measured and calculated temperatures shown together with climatic data for night cooling on 28th May 2015 in Kuching, Sarawak.
The data was input to the model to simulate the 7pm-7am night sky cooling for each month.
Monthly prediction of final Two at 7am in the morning for a year was established from the 5 years climatic data of the this region.

To obtain required accuracy of data transfer between scale levels, 3 windows (0.5×0.4 mm with 100 elements) were included to mesh the rod cross section.
At this point, in the real production at OJSC "MMK-Metiz" reduction of 1-2 mm and die angle of 18 degrees are used.
RVE shows the theoretical possibility of 1.5 time’s increase of reduction with relatively homogenous deformation of the whole rod cross-section.
Influence of reduction degree on the distribution of compressive radial stresses and strains in the central layer Fig. 10.
Therefore, the SSRVE concept was applied in the present paper and the following goals were reached: 1) simplifying and automating the process of creating a microstructure model; 2) reduction of the computing time; 3) reduction of the required computational resources.

Fig. 2 shows reduction currents obtained from Sb-SPCE and Bi-SPCE electrodes.
It was found that increasing pH value caused a decrease in the reduction peak.
However, the reduction peak current was highest at pH 4.0 as shown in Fig. 5.
Briefly, 100 mg.L-1 MT in BR (pH 4.0) containing 12 mg.L-1 of Sb as a catalyst with a selected deposition potential of 1 V (data not shown) was carried out to examine the effect of deposition time on Sb-SPCE.
However, increasing deposition time over 90 s caused a decrease in the reduction peak current.

However, this approach results it difficult separation of catalyst and the reduction product.
There are two reasons to explain these data.
Secondly, annealing can remove some functional groups, but it is not a complete reduction.

Data obtained by this method are of use only in predicting the behaviour of these pipes under condition of temperature, time, method of loading and stress situation.
A notable reduction in elastic modulus occurred at 100% of UEWS (180MPa), when possibly cracks start to develop parallel to the fibres, the reduction was approximately 14% of the virgin pipe.
Reduction in elastic modulus of the filament wound pipe under 2H:1A stress ratio during UEWS test .
At 65°C the strength is generally reduced, with the greatest reduction occurring in the axial load sector, which was about 10%.
This reduction has shrank the failure envelope towards the origin (see fig. 5).

TPST Piyungan encountering problem when the quantity of the incoming waste was not proportional to the reduction of the waste in its final processing.
The WtE technology gives additional uses of decreasing need for landfill area, waste quantity reduction, the reduction of the long distance transportation cost to the integrated waste management site, and the reduction of environmental pollution resulting from the waste processing [9].
Knowledge of Proper Waste Processing Method (left), Opinion of the Best Waste Processing Method (right), Perception of Advanced Waste Processing (Below) (Source: Primary Data, 2019) The majority of the waste pickers in many countries are females, children, and elderly people [12], as well as in TPST Piyungan.
Thermal technology were proposed as alternative in waste processing because of its economic feasibility and require less area with optimal waste reduction percentage [17].

Synthetically, short term experiment data and long term simulated results were considered to decide the optimum air injection position. 2.
In accumulated data, ambient temperature can present the temperature of the lysimeter inside.
This can also be demonstrated by comparing the TOC reduction data in the three lysimeters.
Results shows that the data of simulation meet the experiment data very well, which prove the model is qualified to predict longer period data for reviewing optimum air injection condition.
The initial conditions were given according to previous experiment sampling data.
