![]() The lectrocardiogram, which detects electrophysiological signals from the heart muscle, is considered a favourable monitoring method. Additionally, the main ECG abnormalities in these coal company workers were sinus bradycardia, non-specific intraventricular conduction delay, myocardial ischemia, and sinus tachycardia. ![]() Conclusions: The convolutional neural network model can accurately identify the main ECG abnormality types of coal workers. The test set accuracies of the sinus bradycardia model, nonspecific intraventricular conduction delay model, myocardial ischemia model, and sinus tachycardia model were 97.66%, 96.49%, 93.62%, and 93.02%, respectively sensitivities were 96.63%, 96.30%, 96.88% and 95.24%, respectively specificities were 98.78%, 96.67%, 86.67%, and 90.90%, respectively Brier scores were 0.03, 0.07, 0.09, and 0.11, respectively Calibration-in-the-large values were 0.026, 0.110, 0.041, and 0.098, respectively. Results: The number of abnormal ECG results was 849, and the rate of abnormal results was 25.02%. We use Python software and convolutional neural network to establish ECG images recognition and classification model.We usecalibration curve, calibration-in-the-large, Brier score, specificity, sensitivity, F1 score, Kappa value, accuracy, and area under the curve (AUC) of ROC to evaluate the performance of the model. Methods: Coal workers who underwent physical examinations at Gequan Mine Hospital and Dongpang Mine Hospital of Hebei Jizhong Energy from July 2020 to September 2020 were selected as the study subjects. This site includes each xWorks episode with technical demos, superhero bios, wallpaper downloads, a superhero personality test, and technical deeper dives into each role included within the latest SOLIDWORKS Cloud Offer.īe sure to subscribe to our SOLIDWORKS YouTube channel for more livestream content, and check out more information on previous and upcoming streams.Objective: To process and extract electrocardiogram (ECG, ECG, or EKG) features using a convolutional neural network (CNN) to establish an ECG-assisted diagnosis model. You can follow the xWorks superheroes on. These apps are constantly updated throughout the year, often based on user feedback, with multiple functional deliveries (FDs) featuring new capabilities. Finally, Brad talks a bit about some of the other apps available as part of the SOLIDWORKS Cloud Offer, such as xSheetMetal. With 3DEXPERIENCE SOLIDWORKS, you get access to SOLIDWORKS 3D CAD connected to the cloud. Brad notes that xDesign and xShape also come with 3DEXPERIENCE SOLIDWORKS (with 3D Creator at all levels, and 3D Sculptor available within Professional and Premium). The apps are also modular, so you can buy only what you need. Communication, collaboration, and task management tools are also accessible from the cloud-based platform.īrad also discusses why the SOLIDWORKS Cloud Offer is a logical way to bundle all the most common tools a designer or engineer needs. He accesses all his data via his PC, tablet, or smartphone when he travels. Jordon also extols the virtues of the touch interface and the fact that xShape models can be used downstream since you can automatically convert subdivision surfaces to NURBS geometry.īrad shares his real-life example of the importance and ease of the cloud for collaboration. XShape enables you to quickly create highly stylized, curvature continuous (C2) designs while leveraging subdivision modeling technology in an environment that makes concept modeling as easy as pushing and pulling shapes, just like with a clay model or Play-Doh. Just add geometry where needed and keep moving forward. Eliminate decisions about what features to create first or how to structure the feature tree. Jordan demonstrates how there is no better tool than xShape, which is part of the 3D Sculptor role, for conceptualizing an idea from scratch. Gian also talks about Super Features, the flexibility of the single modeling environment, and the benefit of built-in revision management controls on the 3DEXPERIENCE platform. ![]() And, because xDesign is in the cloud, it enables collaboration with your entire team.īe sure to watch the video of Gian’s favorite features, including Design Assistant, which leverages built-in AI that predicts the best logical next step to speed up subsequent actions. With xDesign, part of the 3D Creator role, our R&D team reimagined the traditional workflows in parametric design. Gian describes how xDesign functions as a core parametric capability for parts and assemblies.
