This study aims to develop a system for extracting crucial information from tire sidewalls using Optical Character Recognition (OCR). Initially, images of tire were captured manually by smartphone cameras, including Redmi 9T, iPhone 11, and Galaxy S23 Ultra. The captured images are then transferred to a computer for storage. Subsequently, these images were cropped according to the boundaries identified by Hough Circle Transform (HCT). The cropped images were then further pre-processed. During the pre-processing phase, geometrical transformation and image sharpening techniques are applied to enhance the clarity and readability of the text images. The text is then extracted using Google Vision, with the extracted text categorized by size, DOT, brand and pattern. The results indicated that the effectiveness of image pre-processing was constrained by the accuracy of circle detection, which reached a maximum rate of 87.1%. This causes parts of the text to be cut out inaccurately, leading to a suboptimal extraction accuracy of 55.65%. It is also observed that the Redmi 9T camera produced inconsistent results compared to other devices. Specifically, the iPhone 11 and Samsung Galaxy S23 Ultra demonstrated superior extraction accuracies of 69.71% and 66.37%, respectively, whereas the Redmi 9T achieved a lower extraction accuracy of 37.76%.

We study the variability of vertically stacked gate-all-around silicon nanosheet (GAA Si NS) complementary field-effect transistors (CFETs). The process variation effect (PVE), the work function fluctuation (WKF), and the random dopant fluctuation (RDF) of CFETs are statistically estimated using an experimentally validated device simulation technique. Among five factors of PVE, the channel thickness (T Nch /T Pch ), the channel width (W ch ), and the gate length (L G ) are significant. Owing to superior GAA channel control and increased effective gate area, both WKF and RDF are suppressed. Notably, the PVE on both N-/P-FETs of GAA Si CFET induce the largest off-state current fluctuations of 80% and 278%, respectively, because the device characteristic is very sensitive to the layer thickness and width of channel.

Alzheimer's disease (AD) is a type of dementia that leads to memory loss and impairment, which afects patients’ lives badly. It is not curable yet, but its progression can be slowed down if detected at earlier stages. In this research study, we propose a transfer learning-based convolutional neural network (CNN) model to classify magnetic resonance imaging (MRI) into one of four stages of Alzheimer's disease. One of the major limitations of the deep learning-based classification model is the non-availability of healthcare datasets related to AD. The widely used Alzheimer's Disease Neuroimaging Initiative (ADNI) dataset has a major class imbalance issue. We propose a generative adversarial network (GAN) based data augmentation technique to overcome the data imbalance. This promotes the investigation of applying GANs to generate synthetic samples for minority classes in Alzheimer's disease datasets to enhance classification performance. The results show the progression in the overall classification process of AD.

Enhancing thermo-physical properties of thermal interface materials (TIMs) is important for efficient cooling of electronic devices. To eliminate air pockets between silicon (Si) die and copper (Cu) heat spreader/sink, TIMs can fill the voids at the interfaces and reduce the contact resistances. In recent, gallium (Ga)-based liquid metals (LMs) have drawn much attention due to their high thermal conductivity and maintained fluidity at room temperature. Previous works have tried to further increase the thermal conductivity by adding conductive fillers to Ga-based LM matrix; however, it is challenging to attain a solder-level thermal conductivity (>60 Wm⁻¹K⁻¹) while maintaining the fluidity. The fluidity gradually decreases due to the solid additives with high volume fraction (>10%) of fillers and significant oxidation, which is a critical issue for applying the LM TIMs to real-world application. To address the issues mentioned above, we incorporated Cu nano-fillers into the Ga-based matrix, excluding the oxidation issues. Through our suggested method, the fabricated LM composite shows over 64 Wm⁻¹K⁻¹ of thermal conductivity at only 4 vol% of copper nano-fillers. The fluidity can be maintained because of the low vol% of additives, which leads to wetting characteristics for the interface between Si and Cu substrate. The mechanism of thermal enhancement is demonstrated by the cluster visualization test, calculating a nanoparticle clustering model. Through the liquid-cooled test vehicle, the thermal performance of synthesized LM composites is assessed. Approximately 33% lowe

In Korea, Chinese cabbage harvesting is insufficiently mechanized and automated, and this task is typically carried out using manual labor. Thus, research on Chinesee cabbage harvesters is required. However, the terrain in cabbage fields is generally rough and comprises many obstacles. Consequently, problems such as overcutting, missed cutting, and side cutting occur while cutting cabbages using a cabbage harvester. Therefore, it is necessary to study the cutting mechanism of the harvester to perform accurate cutting, considering the terrain in the fields. To this end, a three-axis attitude control mechanism was designed in this study;this mechanismm controls the cutting device of the Korean cabbage harvester with three cylinders. In addition, an accelerometer, a gyro sensor, and a rotary encoder were designed for sensor fused. The cylinders were controlled such that the measured roll () and pitch (θ) were level with the ground. In addition, the angle of the guide in the cutting device (θe), driven by grounding to the ground, was calibrated using the height data. The cylinder in the sliding (x) axis was controlled to maintain the target height. Further, a proportional-integral-derivative controller was integrated to reduce overshoot and improve stability. To assess the performancee of the algorithm, a 2:1 scaled-down model of the cutting device of the Korean cabbage harvester was produced, and the attitude control mechanism was installed on its driving platform and tested. Attitude measurement was performed using a motion capture device (OptiTrack). For quantitative evaluation, data with and without the attitude control system were compared by estimating their root mean square error (RMSE). The RMSE values for the level and height were 0.89° and 2.23 cm, respectively, for attitude control with the posture control system;however, those for attitude control without the posture control system weree 2.15° and 4.05 cm, respectively. In addition, improvements of 58% in th

Abstract: In this study, we investigate blood flow in a small artery with a constriction using gold nanoparticles (Au) in the presence of microorganisms, mass, and heat transfer. The non-Newtonian behavior of blood fluid in slight arteries is quantitatively inspected by simulating blood flow using the Carreau fluid model. Momentum equations incorporating magnetohydrodynamics (MHD) and Darcy–Forchheimer porous media are used to model the fluid flow. Heat transfer properties, including thermal radiation, joule dissipation, and bio-convective microorganisms, are investigated. Blood serves as the base fluid for the nanofluid, which contains gold nanoparticles. The system's nonlinear partial differential equations are transformed into nonlinear ODEs through suitable transformations. To obtain numerical solutions for these ODEs, the homotopy analysis method is used. The physical implications of flow restrictions are compared with fictitious fluid flow using physical interpretations. Additionally, investigations into the interpretations of blood flow based on drag force and heat transfer are being conducted. ANOVA, or analysis of variance, is a dependable statistical tool used to evaluate regression models and a variety of statistical tests. These investigations include error assessments, total error evaluations, F-values, p-values, and model fit assessments. These statistical investigations were applied to the dataset at hand, with the goal of achieving a robust 95% level of confidence. We investigate the effects of minute adjustments in parameters on both the heat transfer rate and the friction factor rate using these analyses. The study intends to dive deeper into the potential effects of minor changes in one or more factors on the overall effectiveness of surface friction rate and the larger domain of thermal energy transfer. This will be performed by employing sensitivity analysis approaches. This strategy allows us to obtain a better understanding of how minor change

Humans rely increasingly on sensors to address grand challenges and to improve quality of life in the era of digitalization and big data. For ubiquitous sensing, flexible sensors are developed to overcome the limitations of conventional rigid counterparts. Despite rapid advancement in bench-side research over the last decade, the market adoption of flexible sensors remains limited. To ease and to expedite their deployment, here, we identify bottlenecks hindering the maturation of flexible sensors and propose promising solutions. We first analyze continued...challenges in achieving satisfactory sensing performance for real-world applications and then summarize issues in compatible sensor-biology interfaces, followed by brief discussions on powering and connecting sensor networks. Issues en route to commercialization and for sustainable growth of the sector are also analyzed, highlighting environmental concerns and emphasizing nontechnical issues such as business, regulatory, and ethical considerations. Additionally, we look at future intelligent flexible sensors. In proposing a comprehensive roadmap, we hope to steer research efforts towards common goals and to guide coordinated development strategies from disparate communities. Through such collaborative

WCO is a second-generation biofuel made up of accumulated free fatty acids, which can be used as feedstock for biodiesel production. The review aims to: (a) evaluate the sustainability of waste cooking oil (WCO) for biodiesel production in Indonesia using life cycle sustainability assessment (LCSA) methods;(b) explain the challenges, development, recommendation, and industrial potential of WCO for biodiesel production in Indonesia;and (c) determine the sustainability concept of WCO for biodiesel production. This study was carried out by reviewing papers related to LCSA which include Life Cycle Assessment (LCA), Life Cycle Cost Analysis (LCCA), and Social Life Cycle Assessment (SLCA). The review found that the WCO collection, pretreatment, and transesterification processes have the biggest environmental impact caused by the use of chemicals, catalysts, and electrical energy from fossil fuels. According to the LCCA results, WCO-based biodiesel production has a high economic potential and is more practicable due to lower raw material and production costs than biodiesel from edible and non-edible plants. Meanwhile, the SLCA aspect emphasizes that the WCO-based biodiesel industry must consider social indicators such as employment provision, human rights, human health impact, working conditions, local community impact, cultural heritage, socio-economic repercussions, governance, and large accident risk. There are several recommendations that can be made to develop WCO-based biodiesel, namely the government must demonstrate political commitment by promoting WCO as a national energy source feedstock. The sustainable concept has three pillars: environmental, economic, and social. These pillars must simultaneously direct every stage of the WCO production process. To produce high-quality biodiesel, the government must support all of these stages, establish regulations and governance for WCO supply and the WCO processing industry, and provide implementable R&D, adequate funding
