Background: Paediatric cancer and critically ill patients frequently require central venous catheters for prolonged intravenous therapy. The aim of this study is to compare the difficulty of catheter insertion and the morbidity related to this procedure in these two populations and to investigate risk factors for complications.
Methods: This prospective observational study was conducted at the Hedi Chaker University Hospital in Sfax, Tunisia, from July 2021 to July 2022.
Objectives: Introduced in his paper is a novel approach for the recognition of COVID-19 cases in chest X-rays.
Methods: The discrete Wavelet transform (DWT) is employed in the proposed system to obtain highly discriminative features from the input chest X-ray image. The selected features are then classified by a support vector machine (SVM) classifier as either normal or COVID-19 cases.
