3results about How to "Implement risk assessment" patented technology

The application discloses a bronze harmful rust risk assessment method based on hyperspectral imaging and belongs to the technical field of hyperspectral imaging. The method comprises the following steps: S1, hyperspectral data acquisition; S2, data preprocessing; S3, characteristic wave band extraction; S4, sub-index calculation and corresponding risk judgment; S5, comprehensive risk fusion; S6, environmental factor calculation and corrosion dynamic judgment; S7, risk grade judgment; and S8, prediction and evaluation. The method provides a quantitative, continuous, comparable risk score and discrete operation grade for cultural relic protection personnel, solves subjective dependence and experience difference problems, and realizes a leap from 'qualitative distribution' to 'quantitative risk assessment' and an upgrade from 'picture speaking' to 'digital decision-making'.

This invention provides a method and system for predicting the risk of preoperative condylar bone resorption, relating to the field of oral medicine technology. The method includes the following steps: acquiring and preprocessing small-field CBCT image data of the temporomandibular joint region of the patient to obtain the corresponding region of interest (ROI) of the condylar cancellous bone region; segmenting and extracting features from the ROI of the condylar cancellous bone region to obtain corresponding radiomics features; constructing a condylar bone resorption risk prediction model and inputting the radiomics features into the model for prediction to obtain the corresponding risk prediction results; generating patient risk grading information based on the risk prediction results to assist clinicians in making patient management decisions. This invention, by analyzing and modeling the radiomics features of the patient's preoperative condylar cancellous bone region, achieves the prediction of the risk of postoperative condylar bone resorption without using any postoperative images as prediction input.

The invention belongs to the technical field of safety vertical rods, and particularly relates to a safety vertical rod and method based on TMD vibration reduction and timely alarming. The safety vertical rod comprises a base which is fixed on the ground; the main vertical rod is arranged on the base; the spring reset system is connected with the base and the main vertical rod and is used for elastically limiting the swinging of the main vertical rod; the TMD damper unit is arranged at the top end of the main vertical rod and used for restraining the swing amplitude of the main vertical rod under the wind load; the telescopic safety belt reel is arranged at the top of the TMD damper unit and used for being connected with a safety belt; and the automatic alarm device is arranged at the top end of the retractable safety belt reel, is in signal connection with the TMD damper unit and is used for alarming. By arranging the TMD damper unit and the spring reset system, the inclination angle of the vertical rod under strong wind is reduced, and the wind resistance of the safe vertical rod is improved.
