In this paper, the dynamic characteristics of two types of electromagnetic repulsive force actuators are compared using the simulation of finite element method. The two electromagnetic repulsive force actuators are equipped with a single-sided coil and a double-sided coil respectively. Initially, the construction and theory of each of the electromagnetic repulsive force actuators are discussed. Subsequently,...
The solid-state transfer switch is composed of thyristor valves and vacuum switches in parallel, and thyristor valve series grading is one of important technologies to ensure the normal operation of solid-state transfer switch. Based on the study of static blocking and dynamic switching characteristics of series-connected thyristor and the mathematic model for thyristors, the main causes of voltage...
Objective To get better recognition of central neurocytoma and diminish misdiagnosis. Methods A retrospective review identified 15 cases of central neurocytoma. All cases of central neurocytoma were analyzed for their clinical symptoms, pathologic changes, immunohistochemical staining, prognosis and differential diagnosis. Clinical follow up was performed. Results There were 8 males and 7 females...
