Schupp, Eleen (author)When a person suffers from severe to profound hearing loss, a cochlear implant (CI) can aid in restoring auditory perception and speech comprehension. To obtain good speech comprehension, fitting of a CI to the user’s specific characteristics is crucial. Fitting can be a time-consuming process which requires the cooperation of a CI user and is...master thesis 2023

Wu, Yike (author)Background: Kidney failure, also called end-stage renal disease, means the kidney has lost its function to remove waste from the blood. Patients with kidney failure usually need hemodialysis, which uses a machine to replace the function of a healthy kidney, to keep them alive and prolong their lives. In order to begin hemodialysis, it is crucial...master thesis 2023

Liu, Shurui (author)This article presents a novel wide operational range reconfigurable regulating rectifier for wireless power transfer. The proposed 1X/2X/3X rectifier achieves wide range voltage regulation without global loop control to minimize the area occupation. Compared with previous work, more working modes and greater magnification allow the proposed...master thesis 2022

Karim, Tawab (author)Treatment of diseases, illnesses or disorders are always sought without any undesired side-effects and complications. Neurological disorders, such as Epilepsy and Parkinson’s, are currently treated using pharmaceuticals. However, drugs have a low specificity and lose their effectiveness after several years. In addition, prolonged drug usage...master thesis 2022
