To improve the accuracy of calibration of C-arm, and overcome the space limitation in surgery, we proposed a new calibrator for online calibration of C-arm.After the image rectification by a polynomial fitting-based global correction method, the C-arm was assumed as an ideal pinhole model.The relationships between two kinds of spatial calibration e
Norovirus is one of the leading causes of gastroenteritis, acute vomiting, intense diarrhoea, acute pain in the stomach, high fever, headaches, and body pain.Conventional methods of detection gave us very promising results but had disadvantages such as low sensitivity, cost ineffectiveness, reduced specificity and selectivity, etc.Therefore, biosen
Situated within the context of a soft ground foundation at an iron ore mining site, this study investigates the impact of substantial surcharges on the settlement of such foundations and the adjacent infrastructure.By employing the finite-difference numerical software FLAC3D 6.0, a series of three-dimensional simulations were conducted to assess th
