The application provides an explainable analysis method and system for burn prediction results, and belongs to the technical field of intelligent burn analysis. The method is to set a target result, continuously adjust biomarkers corresponding to the burn prediction result, obtain improved biomarkers, use a random forest model to predict the improved biomarkers to obtain improved results, continuously adjust the biomarkers corresponding to the burn prediction result until the improvement target is reached, and then explain and analyze the burn prediction result according to the improvement target. The technical problem that the existing technology cannot perform explainable analysis on the grading and typing prediction results by using the machine learning method is solved, a clinically understandable decision basis is formed, and systematic computing support is provided for burn diagnosis and treatment.

The invention relates to a device and method for adjusting the height of a rigid protrusion of a nuclear fuel assembly grillwork strip. The device comprises a height reducing male die punch, a height reducing female die punch, an upper die frame, a height increasing male die punch, a height increasing female die punch and a lower die base. The height reducing male die punch and the height increasing male die punch are embedded in the inner side of the upper die frame in a module mode. The height reduction female die punch is embedded in the position, right opposite to the height reduction male die punch, of the inner side of the lower die base in a module mode. The heightening female die punch is embedded in the position, right opposite to the heightening male die punch, of the inner side of the lower die base in a module mode. By designing the device for synchronously and reversely adjusting the heights of the rigid protrusions on the same side of the strip, the technical problems that when a nuclear fuel assembly grillwork G factor is unqualified, the efficiency of the processes of rigid protrusion height adjustment, measurement judgment, readjustment and the like in the grillwork is low, and batch production is not facilitated are solved, and meanwhile the problem that after the strip rigid protrusion height is adjusted, the production efficiency is low is solved. The appearance, the size, the crack and the like of the rigid bulge are inconvenient to detect.

The application discloses a kind of active front wheel steering time delay feedback controller parameter time delay feasible region's calibration method, and include steps: 1) the vehicle system model of active front wheel steering feedback controller including time delay is established;2) by constructing Lyapunov-Krasovskii functional, time delay independent stability parameter region is solved;3) by Laplace transform solving system characteristic equation, obtain stability discriminant polynomial;4) it is solved to the minimum critical time delay that can be tolerated under time delay independent stability region and time delay related stability zone under different control parameter combinations of system.This application can provide reference for controller stability design, compared with traditional active front wheel steering controller without considering time delay, can more effectively judge whether system meets stability requirement, and reduce control parameter adjustment range, so as to reduce test cost in actual engineering, guarantee the stability of vehicle control system.

A tubing end cutting tool includes conveying tracks, positioning assemblies and clamping assemblies. The conveying tracks are two and are arranged in sequence along the conveying direction of the conveying tracks and are used for conveying the tubing. The positioning assemblies are two and are arranged above the conveying tracks and include two support plates arranged on the two sides of the conveying tracks and moving along the vertical direction. A plurality of pressing blocks are arranged above the support plates along the length direction of the support plates and are used for limiting the tubing. The clamping assemblies include a lifting frame arranged between the conveying tracks and moving along the vertical direction. A plurality of baffle plates are arranged on the two sides of the lifting frame along the circumferential direction of the lifting frame and move along the radial direction of the lifting frame synchronously. The baffle plates are provided with clamping blocks on the side away from the center of the lifting frame. The clamping blocks located below move along the thickness direction of the lifting frame and are used for clamping the end of the tubing. The end of the tubing is clamped, the end of the tubing is conveniently transferred and the tool has strong practicability.

The application relates to the field of light and shadow projection equipment, and discloses an automatic adjustment method for a projection area of a projector. Through the cooperation of a projection offset module and a projection zoom module, the projector can automatically correct the position and size of a projection image by using a start-up image during a start-up process, so that the projection image of the projector is clearer, the visual effect during watching is better, the adjustment process is automatic, personal participation is not needed, the use of the projector is more convenient, and the cooperation of a grid division module divides the projection image into regions, so that the position of an occlusion and the distance that needs to be adjusted by the projection image can be clearly known. Therefore, the adjustment process is more rapid and smooth, the trial and error times of the equipment are reduced, the projection image can be maximized in the case of avoiding occlusion, and the best visual effect is reserved.

The embodiment of the present application provides a kind of LED screen brightness adjusting method, device, system and electronic equipment.In the present embodiment, the screen brightness of LED screen is adjusted by target current gain and target Gamma value together, reduces the Gamma value adjustment range, reduces the situation that the contrast of screen is lost caused by the method of adjusting only Gamma maximum value to the brightness of LED screen, realizes the adjustment to screen brightness in the case where the contrast of screen is basically unchanged, improves screen display effect.
