Most trackers can hardly top the performance and work in real time. This paper presents a tracking framework based on the SiamFC network, which can be taught online from the beginning of tracking and is real time. SiamFC network has a high tracking speed but cannot be trained online. This limitation made it unable to track the target for a long time. Hybrid-Siam can be trained online to distinguish target and background by switching traditional tracking and deep learning methods. Using the traditional tracking method and a target detector based on saliency detection has led to long-term tracking. Our method runs at more than 60 frame per second during test time and achieves state-of-the-art performance on tracking benchmarks, while robust results for long-term tracking.

In this context, AlSi10Mg (wt%) alloy was produced by gravity die casting method, and then, air cooling, quenching, and T6 treatment were applied. The microstructure of the alloy was investigated using an optical microscope, SEM, and EDS. Additionally, thermogravimetric analysis (TGA) was used to determine the effect of processing parameters on the oxidation behavior of the samples. The friction and wear properties of the alloy were investigated using a ball-on-disk wear test device. It was founded that the as-cast AlSi10Mg alloy's microstructure contained phases of α(Al), Si, and β-Mg₂Si. It has been observed that the microstructure of the cast AlSi10Mg alloy gradually turns into a spherical form when quenching and air-cooling heat treatments are applied. Also, T6 heat treatment led to further spheroidization of Si particles, formation of β-Mg2Si precipitates, and elimination of the Chinese script morphology of the β-Mg₂Si phase. It was observed that the yield strength of the AlSi10Mg alloy in the as-cast state decreased negligibly compared to the air-cooled state, while there was an increase of up to 70% in the aging-treated condition. The results show that the tensile strength of the as-cast AlSi10Mg alloy increased by 115% after aging. Additionally, it was found that the AlSi10Mg alloy's wear resistance increased with the aging process.</p></div>","PeriodicalId":54354,"journal":{"name":"Arabian Journal for Science and Engineering","volume":"49 11","pages":"15335 - 15346"},"PeriodicalIF":2.6,"publicationDate":"2024-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s13369-024-08971-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140695768","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These green MWFs have often been evaluated for their tribological behavior and machining performance under various operating conditions. However, very few studies have analyzed the green metalworking fluids' ecological and eco-toxicological characteristics. With an aim to explore the potential impact and the related concerns of the developed green MWFs on the environment and eco-life, ecological and eco-toxicological experimental studies were performed in this research. This research study offers a comprehensive analysis of the biodegradability, soil eco-toxicity, cell viability, corrosion responsiveness, and reusability characteristics of the in-house developed nanoparticles-modified vegetable oil MWFs (MVO-MWFs). The findings from biodegradability studies demonstrate the inherent and readily biodegradable nature of the developed MWFs. Subsequently, soil eco-toxicity tests reveal the non-harmful nature of developed MWFs to the ecological organisms at the tested concentrations. Furthermore, during the cell viability assays, no evidence of cell death was observed in normal and cancer-affected cells under tested conditions. Additionally, the reusability studies on MQL imply that a considerable amount of MWF can be collected and reused to enhance the sustainability of the MWF system. This study established a decision-making approach to identify the optimal NP-based MWF combination by correlating multivariate data. Based on this work, a step-by-step methodology is recommended with four decision points to conduct a series of ecological and eco-toxicological protocols for the new or existing NP-based MWFs.

One of the most effective methods for separating these particles is a cyclone separator, which can quickly and efficiently remove hazardous particles from the air. In this research, the separation of silica particles using a cyclone separator was investigated and analyzed using artificial neural networks (ANNs) and response surface methodology. The influence of process parameters, including flow rate, particle size, and speed, on cyclone efficiency was investigated. The cyclone experiments were carried out with varying rotation speeds ranging from 0 to 1900 rpm, as well as different particle sizes (15, 25, and 40 μm) and flow rates (30, 50, and 70 m³/hr). Based on the research findings, it was discovered that the ANN model that utilized the multilayer perceptron (MLP) algorithm outperformed the one that used the radial basis function (RBF) algorithm. The findings showed that a neural network with a multilayer perceptron (MLP) architecture performed well in predicting efficiency. Specifically, this MLP had one hidden layer consisting of 10 neurons, and its topology was defined as 3-10-1. The accuracy of the efficiency predictions was high, with a coefficient of determination of 0.998.

The base fluid chosen for this study is water (H₂O), while the nanoparticles iron oxide (Fe₃O₄) and cobalt ferrite (CoFe₂O₄) are utilized to create the hybrid nanofluid. An appropriate method of similarity transformation is executed along a set of partial differential equations (PDEs) that were reduced to a system of nonlinear ordinary differential equations (ODEs). Numerical outcomes were then obtained via bvp4c in MATLAB software, with the influence of various parameters such as nanoparticle volume fraction, homogenous/heterogenous reaction strength parameters, suction, shrinking/stretching parameters, and radiation parameter. Additionally, asymptotic analysis was conducted to show that the concentration boundary layer on the disk can be performed subject to a large number of suctions. The present findings reveal that a rise in the volume fraction of nanoparticles results in a reduction in radial velocity profiles, temperature profiles, and tangential fields. As thermal radiation levels rise, a notable reduction in the local Nusselt number is evident.
