Abstract The voltage is unstable due to the influence of load demand and other factors. In order ensure stable operation power system, this paper proposes a method system stability margin prediction based on gradient lifting decision tree. On basis, sampling grid established by using data mining solved. combined with simulation curve grid, characteristics are analyzed, analyzed CNN model propos...

INTRODUCTION: Diffusion Weighted Imaging (DWI) techniques have improved due to increased magnetic field strength and improved Radio Frequency (RF) and gradient coil performance[1]. Improved gradient performance is used to shorten the echotrain duration and increase the number of echoes in the same duration, thereby reducing susceptibility artifacts[2,3]. In this study, we combine a home-built i...

objective: the aim of this study was to examine the efficiency of ha-binding test and sperm gradient processing method for the selection of sperm with normal protamine, intact dna and normal morphology. materials and methods: the study was conducted on 29 patients undergoing icsi. semen analysis was carried out according to who criteria. semen samples were divided into three equal portions. one...
