    Researchers from School of Intelligent Manufacturing Discuss Findings in Robotic s (Fixed-Time Sliding Mode Control for Robotic Manipulators Based on Disturbance Observer)

    47-48页
    查看更多>>摘要:By a News Reporter-Staff News Editor at Robotics & Machine Learning Daily News Daily News – Research findings on robotics are disc ussed in a new report. According to news reporting from the School of Intelligen t Manufacturing by NewsRx journalists, research stated, “A novel controller usin g fixed-time sliding mode (FTSM) and fixed-time disturbance observer (FTDO) is p roposed to achieve trajectory tracking control of robotic manipulators.” Funders for this research include West Anhui University. Our news editors obtained a quote from the research from School of Intelligent M anufacturing: “First, the mathematical model is established for robots with dyna mic model uncertainties and external disturbances. An FTSM control strategy is p resented where the integral terms of position errors are introduced into the exi sting sliding mode surface (SMS) to reduce the steady-state error of the system. The exponential form in the integral terms can provide an appropriate control f orce for tracking systems when the position errors are far from the sliding surf ace for a long time. Then, an FTDO is designed to obtain a precise estimation of lumped disturbances which can be used to weaken the impact of disturbances on t he control accuracy. Finally, the fixed-time convergence properties of the track ing control system are demonstrated using Lyapunov stability theory.”

According to news reporting ori ginating from Astana, Kazakhstan, by NewsRx correspondents, research stated, “Th e COVID-19 pandemic highlighted the need for accurate virtual sizing in e-commer ce to reduce returns and waste. Existing methods for extracting anthropometric d ata from images have limitations.” Our news editors obtained a quote from the research from Astana IT University, “ This study aims to develop a semantic segmentation model trained on synthetic da ta that can accurately determine body shape from real images, accounting for clo thing. A synthetic dataset of over 22,000 images was created using NVIDIA Omnive rse Replicator, featuring human models in various poses, clothing, and environme nts. Popular CNN architectures (U-Net, SegNet, DeepLabV3, PSPNet) with different backbones were trained on this dataset for semantic segmentation. Models were e valuated on accuracy, precision, recall, and IoU metrics. The best performing mo del was tested on real human subjects and compared to actual measurements. U-Net with EfficientNet backbone showed the best performance, with 99.83% training accuracy and 0.977 IoU score. When tested on real images, it accurately segmented body shape while accounting for clothing. Comparison with actual meas urements on 9 subjects showed average deviations of -0.24 cm for neck, -0.1 cm f or shoulder, 1.15 cm for chest, -0.22 cm for thallium, and 0.17 cm for hip measu rements. The synthetic dataset and trained models enable accurate extraction of anthropometric data from real images while accounting for clothing. This approac h has significant potential for improving virtual fitting and reducing returns i n e-commerce.”

    New Robotics Study Results Reported from University of Sao Paulo (Ankle Torque E stimation Based On Disturbance Observers for Robotic Rehabilitation)

    New Findings from Mayo Clinic in the Area of Machine Learning Reported (Computat ional Flow Cytometry Accurately Identifies Sezary Cells Based On Simplified Aber rancy and Clonality Features)

    52-52页
    查看更多>>摘要:By a News Reporter-Staff News Editor at Robotics & Machine Learning Daily News Daily News – Data detailed on Machine Learning have been presented. According to news reporting originating in Rochester, Minnesota , by NewsRx journalists, research stated, “Flow cytometric identification of cir culating neoplastic cells (Sezary cells) in patients with mycosis fungoides and Sezary syndrome is essential for diagnosis, staging, and prognosis. Although rec ent advances have improved the performance of this laboratory assay, the complex immunophenotype of Sezary cells and overlap with reactive T cells demand a high level of analytic expertise.” The news reporters obtained a quote from the research from Mayo Clinic, “We util ized machine learning to simplify this analysis using only 2 predefined Sezary c ell- gating plots. We studied 114 samples from 59 patients with Sezary syndrome/ mycosis fungoides and 66 samples from unique patients with inflammatory dermatos es. A single dimensionality reduction plot highlighted all TCR constant b chainrestricted (clonal) CD3+/CD4+ + /CD4 + T cells detected by expert analysis. On receiver operator curve analysis, an aberrancy scale feature computed by compari son with controls (area under the curve = 0.98) outperformed loss of CD2 (0.76), CD3 (0.83), CD7 (0.77), and CD26 (0.82) in discriminating Sezary cells from rea ctive CD4+ + T cells. Our results closely mirrored those obtained by exhaustive expert analysis for event classification (positive percentage agreement = 100% , negative percentage agreement = 99%) and Sezary cell quantitation (regression slope = 1.003, R squared = 0.9996).”

According to news reporting originating from M ecca, Saudi Arabia, by NewsRx correspondents, research stated, “In the electroni c era, the demand for efficient storage systems has rapidly increased, making th e health and durability of batteries crucial. This research investigates the per formance of distinct Machine Learning (ML) techniques-namely, Logistic Regressio n (LR), Convolutional Neural Network (CNN), and CNN performance tuning using Par ticle Swarm Optimization (PSO)-for Battery Health Analysis (BHA).” The news reporters obtained a quote from the research from Umm Al-Qura Universit y: “The dataset comprises various parameters related to battery health, with Rem aining Useful Time (RUL) as the target variable. The proposed work is evaluated using Root Mean Squared Error (RMSE), Mean Absolute Error (MAE), and R-squared ( R2) scores. Initially, the basic LR Model is employed for BHA, followed by the C NN Model to capture complex data patterns. Subsequently, the CNN Model’s perform ance is optimized using the PSO algorithm, aiming for improved performance. Expe rimental results demonstrate that the CNN Model significantly outperforms the LR approach in terms of accuracy, lower RMSE and MAE, and higher R2 scores. The co nventional CNN model significantly outperformed the LR approach, resulting a low er RMSE of 20.11, MAE of 15.26, and higher R2 score of 0.996; whereas, the PSO-O ptimized-CNN further enhanced the performance metrics with RMSE of 14.97, MAE of 8.03 and R2 score of 0.998.”
