This paper investigates the relationship between various types of spectral clustering methods and their kinship to relaxed versions of graph cut methods.This predominantly analytical study exploits the closed (or nearly closed) form of eigenvalues and eigenvectors of unnormalized (combinatorial), normalized, and random walk Laplacians of multidimen
Abstract Background Retroaortic innominate vein is a rare anomaly.It has been reported in patients with congenital anomalies such as Tetralogy of Fallot or right aortic arch.However, isolated retroaortic innominate vein is quite rare.Case presentation A 63-year-old 30x24x24 wall cabinet man was transferred to our institution because of Stanford typ
The detection of the impurity rate in machine-picked seed cotton is crucial for precision agriculture.This study proposes a novel Cotton-YOLO-Seg bostik roll-cote cotton-impurity instance segmentation algorithm based on the you only look once version 8 small segmentation model (Yolov8s-Seg).The algorithm achieves precise pixel-level segmentation of
The flow-induced vibration characteristic of the U-section rubber outer windshield structure of high-speed train is the key factor to limit its high-speed movement.Accurate and effective flow-induced vibration analysis of windshield structures is an important topic.In this paper, a hybrid modeling method for the analysis of flow-induced vibration o
