Published: August 2023

One of the most significant challenges of the mining industry is resource yield estimation from visual data. An example would be identification of the rock chunk distribution parameters in an open pit. Solution of this task allows one to estimate blasting quality and other parameters of open-pit mining. This task is of the utmost importance, as it is critical to achieving optimal operational efficiency, reducing costs and maximizing profits in the mining industry. The mentioned task is known as rock fragmentation estimation and is typically tackled using computer vision techniques like instance segmentation or semantic segmentation. These problems are often solved using deep learning convolutional neural networks. One of the key requirements for an industrial application is often the need for real-time operation. Fast computation and accurate results are required for practical tasks. Thus, the efficient utilization of computing power to process high-resolution images and large datasets is essential. Our survey is focused on the recent advancements in rock fragmentation, blast quality estimation, particle size distribution estimation and other related tasks. We consider most of the recent results in this field applied to open-pit, conveyor belts and other types of work conditions. Most of the reviewed papers cover the period of 2018-2023. However, the most significant of the older publications are also considered. A review of publications reveals their specificity, promising trends and best practices in this field. To place the rock fragmentation problems in a broader context and propose future research topics, we also discuss state-of-the-art achievements in real-time computer vision and parallel implementations of neural networks.

Authors: Du Xiongxiong , Han Xiaoling , Lei Ceyu
Published: August 2023

In this paper, we investigate a nonlinear discrete prey-predator system with fear effects. The existence, local stability and boundedness of positive equilibrium point are discussed. Using the center manifold theorem and bifurcation theory, the conditions for the existence of flip bifurcation and Neimark-Sacker bifurcation in the interior of $ \mathbb{R}_{+}^{2} $ are established. Furthermore, the numerical simulations not only show complex dynamical behaviors, but also verify our analysis results. A feedback control strategy is employed to control bifurcation and chaos in the system.

Authors: Chen Chao-Fu , Wang Shu-Fan , Shen Xing-Xing , Liu Lei , Wu Hui-Ju
Published: August 2023

The purpose of this study was to examine the effect of neuromuscular electrical stimulation (NMES) immediate intervention training on the countermovement jump (CMJ) height and to explore kinematic differences in the CMJ at each instant. A total of 15 male students who had never received electrical stimulation were randomly selected as the research participants. In the first test, the CMJ performance was completed with an all-out effort. The second experiment was best performed immediately to complete the CMJ operation after NMES for 30 min. Both experiments used a high-speed camera optical capture system to collect kinematic data. The results of this experiment revealed that after im-mediate NMES training, neuromuscular activation causes post-activation potentiation, which increases the height of the center of gravity of the CMJ and affects the angular velocity of the hip joint, the velocity and acceleration of the thigh and the shank and the velocity of the soles of the feet. The use of NMES interventional training based on the improvement of technical movements and physical exercises is recommended in the future.

Published: August 2023

This study sought to investigate the role of local and regional authorities in inclusive, resilient and green recovery for sustainable development using Greece as a case study. A questionnaire was used to collect data from 190 local and regional leaders in different authorities in West Macedonia - Greece from private and public sector. The study found a positive and significant relationship between green, resilient, and inclusive recovery practices and sustainable development. It would be less successful to attack the socioeconomic, climate change, and biodiversity issues separately than to develop a coordinated strategy to address their interrelated consequences. The underlying economic deficiencies would not be addressed by maintaining existing growth patterns. The trade-offs from ignoring the links increase in cost every day as the loss of forests, seas, and other natural resources worsens, and often the poor and vulnerable are those who suffer the greatest disadvantages.

Authors: Renugadevi P. , Maheswari R. , Pattabiraman V. , Srimathi R.
Published: August 2023

Electrification is a primary concern in the recent years because of new emerging technologies in day-to-day life. Therefore, to run a variety of devices, you need an uninterrupted power supply, and equipment that is powered as well. There are various reasons such as natural disasters, transmission, and distribution issues that prevent 30% of residents in rural and isolated areas from accessing basic electricity. This lack of electrification has an adverse effect on people's survival on radical level in many circumstances. It may be possible to reduce both current and future power constraints by improving the microgrid concept so that standalone microgrids in remote locations work well. Especially when isolated from main grids and unable to receive regular electricity, standalone microgrids present many difficulties and problems. Formerly, diesel generators were considered indispensable to off-grid microgrids, as they provide electricity for the entire system. Power losses can be reduced by employing power optimizers with a maximum power point tracking approach.

In this study, activation energies required for the static recrystallization behavior during the annealing process after cold deformation of Al-Mg-Si alloy to which zirconium was added in various proportions were investigated. Depending on the zirconium content, the activation energies of the alloys were found and compared both experimentally and by calculation. For this purpose, alloys containing 0.1, 0.2 and 0.3 wt-% Zr were cold rolled after taking into solution and quenching. And then, the alloys were annealed at 375 °C and 500 °C for different annealing times. After the alloys were prepared metallographically, their grain structures were examined microscopically. Depending on the temperature, recrystallization-% was found by image analysis and experimental recrystallization-% curves were drawn. The time taken for recrystallization-50% to experimentally find the activation energy required for recrystallization to occur was found from the curves. These values were replaced in the relevant formulations and the required activation energy was experimentally found from the slope of the Arrhenius equation and the ln t50% and 1/T graph. In order to find the recrystallization-% by calculation, the nucleation rate and growth rate of the new recrystallized grains were found by image analysis. By substituting these values in Johnson-Mehl-Avrami equation, the calculated recrystallization-% curves of the alloys were found. From here, using the relevant equations, Arrhenius equation was passed and the activation energy was calculated from the slope of ln k and 1/T graph. The results showed that the activation energy increased with the increase of the zirconium ratio, and even the most effective zirconium ratio was between 0.1-0.2% by weight in increasing the activation energy. Therefore, this ratio should be considered in processes where recrystallization, which also affects other properties of the alloy, is not desired.

Deterioration of metals and alloys due to corrosion has been observed to be a serious challenge in coastal or marine environments. Exposure of mild steel to marine environments often results into dilapidation of physical structure over time. This study addresses the quick response of mild steel failure using NiZnP modified Al2O3 functional composite by electrolytic process. The deposition was done with stable pH of 4.5, heated bath temperature of 95°C, stirring rate of 200 rpm and deposition time of 20 min. The materials chemistry of the developed alloy was examined using open circuit potential and linear polarization technique. The structural mechanism and crystal phase formation was characterized using scanning electron microscope (SEM) equipped with energy dispersive spectrometer (EDS) and X-ray diffraction analyzer. The corrosion results under 3.65% saline environment reveals improved corrosion rate of NiZnP modified Al2O3. The surface site of the crystal formation evolves perfectly with hexagonal structure seen along the grain boundaries.

This study develops an absorber containing abaca fiber (Musa Textiles) and epoxy resin as a binder. The ability to absorb sound energy is related to the pore’s size present in the absorber. One of the methods to create porosity is to vary the length of fiber, which is 1, 10 mm, 15 mm and 20 mm. Before the fiber is cut to be certain length, it is treated employing NaOH alkalization and acetic acid hydrolysis. The characterization carried out includes density, morphology and absorption coefficient measurement using impedance tubes. Moreover, the fibers are measured for the density, then continued to determine the porosity and air flow resistivity using the Konzeny-Carman equation. The air flow resistivity parameter is utilized to determine the absorption coefficient using Delany-Bazley model. The value of the absorption coefficient from experiments using impedance tubes and based on theoretical analysis shows a similar trend curve. The results show that the fiber with the length of 20 mm exhibits the highest sound absorption coefficient.

The population growth and the industrial revolution caused severe environmental pollution, especially pollution of clean water availability. Several ways have been conducted to overcome the pollution of clean water availability, one of which is by the adsorption of metal and cellulose-based waste materials as a hybrid catalyst. This study aims to fabricate and modify a hybrid catalyst composed of cellulose in the form of nanosized fibrils. Cellulose can be used as a catalyst by incorporating Fe from magnetite (Fe3O4) and can work effectively as an adsorbent for methylene blue (MB) dye waste. The method used in this research is a modified coprecipitation method by combining cellulose and Fe3O4 nanoparticles. Hybrid Catalyst of Fe3O4/Cellulose Nanocomposite-Base has been successfully characterized by using XRD, SEM-EDX, and UV-Vis, respectively to determine the particle structure, morphology, and adsorption capacity of the sample. The results of data analysis showed that Fe3O4/Cellulose could purify MB solution depending on the ratio of Fe3O4 and the mass of cellulose used. The higher the mass ratio of cellulose to Fe3O4, the absorbance value of the Fe3O4/Cellulose nanoparticle sample increases.
