They also give recommendations for the starting and stopping of conveyors, such as the allowable maximum belt tension, minimum safety factor, and start-up time.
The main properties of the belt conveyor are as follows: the desired operational speed is 4 m/s, the centre-to-centre distance is 960 m, the number of belt elements is 60, the length of each belt element is 32 m, the tail pulley and the loading station are both at node 31, the discharge point and the tension device are both at node 1.
When the reflection of acceleration and deceleration waves in the belt arrive at motor 1, the nodal velocity at that location is affected, resulting in the ups and downs of the drive wheel slip and drive force.

The properties of organic polymers implanted with low-energy ions are of scientific and practical interest.
By ion-beam technology one can significantly improve the optical characteristics [14, 20–24], electronic properties [24–29], electrical conductivity [14, 25–27, 30], biocompatibility [31, 32], surface, mechanical and thermal properties [25–27, 30] of optically-transparent synthetic polymers, such as polymethylmethacrylate (PMMA) and polycarbonate.
As known, the carrier transport depends on various factors, on the interaction between the gate dielectric and the semiconducting active material, as well as on the morphology of the interfacial region between them.

Nonlinear elastic layers are considered to have different mechanical properties.
Since the structure of the plate is arbitrary in thickness and non-symmetric, this significantly affects the structure of the coefficients .
In the K0-3 approximation they have the following form: (); ; ; (11) ; , , steels depend on mechanical and geometric parameters.
All operators and functions depend on the mechanical and geometric parameters of the plate.

For the last few years investigations into parameters that affect velocity and temperature of several types of fluids, to include viscoelastic materials, have been investigated.
An investigation into how relaxation time affects the flow of viscoelastic material in a two-dimensional cavity was conducted by Khan et al. [10] using Galerkin’s Finite Element Method.
The spectral homotopy analysis method was used to determine how the viscoelastic parameter as well as viscous dissipation affected the fluid flow.
This could be attributed to the elastic properties of the viscoelastic material, which causes some internal vibrations.
Conclusions This paper examined the time-dependent MHD rotating Couette motion of Maxwell material with ramped temperature, with the aim of identifying the factors influencing the viscoelastic material’s velocity and temperature.

Nevertheless, PR must solve still some technological problems, as well as the problem of the distribution of the material properties [3]: small distributions of the orientation and of the anisotropy increase the transition parameter, while SNR varies opposite to the second power of this parameter.
The intergranular exchange coupling can affect the second step of the switching process, leading to a steeper hysteresis loop, but has poor effect on the first step [14].
If this interlayer is missing and the intragranular exchange coupling is strong, we talk about exchange spring media, proposed as a way to increase the quality factor of permanent magnets.
Such an increase of f0 facilitates the writing process but affects the archivability, as results form the equation [17] , (4) where t is the measurement time, H is the applied field and .
(The adjacent track erasure is today a key factor limiting recording density!)

However, one of the determining factors affecting the reliability of modeling results is the parameters of the finite element mesh.
In this case, using the Edge Sizing approach, the Number of divisions parameter was 30, but with the Bias Factor option for density in the center of the plate, where the bullet contacts the steel plate, as shown in the figure. 5.
This is explained by the physical properties of the plate material, since nonlinear steel is an isotropic plastic material characterized by significant plastic deformation before destruction.

As a result of these factors, the composites so-synthesized may attain inferior mechanical properties.
The wear resistance of dispersion-strengthened materials is dependent on several factors including the size, shape, quantity and quality of the dispersion.
Another influential factor is the wettability between the molten matrix and the solid reinforcement.
This factor may have prevented completion of the reaction to utilise the entire Ti-graphite.
Thus, the above mentioned factors jointly facilititate and sustain the Ti-C reaction bringing about more effective generation of finer TiC particles with improved degree of uniformity of their distribution in the matrix.

Two-factor central composite design Fig. 2.
The material and geometric properties are usually adopted as input features (parameters) in model updating.
The Young's modulus (E0=35.5GPa) and the density (D0=2400 kg/m 3) measured from the concrete specimen tests were used as the initial values of the material properties for the FEM.

Several methods can be used to process biomass into syngas, namely thermochemical, biochemical, and mechanical extraction.
This is because O2-based gasification agents will affect CO and CO2 products more as described by Basu, Phabir[4] in his research.
Likewise, what happens in the CO partial combustion reaction which has exothermic properties, with the high energy received, the reaction shifts toward the reactants.
In this simulation, with the operating conditions suggested by Antonini, Cristina.[8] in their research, making the ratio 2:1 mol MDEA/ CO2 can capture 99.9% of CO2 in the flow Fig. 10 Effect of MDEA Flowrate on CO2 In this simulation, the MDEA solution used is very large, this will affect the financial factor if it must continuously supply MDEA solution.
The temperature of the gasification reactor also affects the gas products produced, the increase in operating temperature helps gaseous products such as CO2 and H2 to form and removes gases such as CH4.
